It is true that acquiring new language skills is by no means an easy task. Language learners might encounter several challenges such as unfamiliar accents or grammar structures in the learning process of a foreign language. However, in my opinion, such difficulties can be tackled by a well-rounded education system.

When it comes to languages, it is undeniably crucial to get used to a native accent and intonation for effective communication. However, picking up an accurate accent can be enormously difficult, especially for adult learners because of their lack of language learning ability. If a language learner has an unrecognisable accent and intonation, they would not be understood by native speakers. On top of that, each language has different grammar and typical grammatical sequencing of words. For example, Korean sentences always end with verbs whilst English does not, which means that a Korean English-learner should consider about the correct order of

words.

Despite the aforementioned difficulties, I strongly believe that everyone can master a foreign language when a couple of feasible steps are taken. Firstly, it is more important than anything to start learning a new language at a young age. By incorporating foreign language programmes in the primary school curriculum, children can easily be exposed to languages of the world and eventually acquire language skills without difficulties. Secondly, the government can financially subsidise schools to run student exchange programmes that help adolescents to get experiences abroad and make friends overseas while improving their foreign language in a delightful way.

In conclusion, I believe that individuals can have difficulties in learning a new language because of different accents and unfamiliar grammar, however, these problems can be overcome by a good quality of education system subsidised by governments.

It is argued that to become competent in another nation’s language is a quite difficult job. This essay will suggest that finding a partner for practice is the main difficulty that people face and the best way to overcome this is by joining a group of people who are learning a particular language.

The primary problem that people have to tackle while they start learning a foreign language is a lack of practice. This is because there are very few people around their vicinity who have a keen interest in becoming proficient in another language. Without practice, they will not have enough command on the language which they are learning. For example, a recent survey by Cambridge University found that 55% of people admitted that they were not able to practice a newly learned language because they did not find anyone to practice with.

The best solution to this problem is to join a group where people are already practising the same language which they intend to learn. The members of the group share their experiences of how they are able to master a new language and the group discussions in a community enable them to have enough practice. This will make people fluent in the language. To illustrate, I was struggling a lot in learning English and my friend suggested me to join a local English learners group which I did. After a few weeks, I saw a drastic improvement in my language ability.

In conclusion, the main issue that people face while mastering a foreign language is a lack of sessions for practice. The best way to solve this is on joining a group of language learning enthusiasts.

Learning a new language is indeed a herculean task for many, especially when it comes to adults. This essay will explore the factors which make learning a new language challenging and will also suggest some potent solutions to deal with the same.

To begin with, grown-ups particularly find it difficult to learn foreign vernaculars because as they grow, their brains lose that flexibility to adapt to any language and become hard-wired to specific languages that they speak or know since childhood. Moreover, the level of intelligence in an individual also matters as some people are blessed with superior cognition and hence are better equipped for learning an alien language. Also learning coherence and cohesion is the hardest part as one can learn vocabulary and rules of a language but putting them in order to make a grammatically correct sentence comes with a lot of struggle and practice. People also tend to apply their native tongue’s grammar and characteristics to make sense of an identically structured foreign language. Research conducted by Mark Pagel, an evolutionary biologist at the University of Reading in the U.S.A. states that the brain affects one’s thoughts and perceptions and it alters the way one thinks, hence our mother tongue tends to dominate our neural system which makes adhering to other languages an ambitious task.

To cope with this, firstly, although people may feel silly when they make mistakes while learning and practising a language, they must not feel bad about it or pretend to be perfect as everyone learns by making mistakes. An excellent approach is to uptake some other activity or skill and take instructions in the language to be learnt. For instance, in California ‘apprentice’ programmes are run in which apprentices pair up with the speakers of native American tongue to learn a traditional skill such as basket weaving, with instructions exclusively in the native language. After a certain time, learners become well-versed with that language. Furthermore, aspirants must also naturally try to get used to listening and understanding the language by watching foreign movies with descriptions in the form of subtitles in a known language through applications like Netflix as by doing so they come across various slangs, range of vocabulary and grammatical structures of sentences. It is an interesting way to grasp a language.

In summary, one needs to be motivated enough to get used to and memorize foreign languages. The advent of social media has eased this process as folks can converse with the native speakers and gain a lot of knowledge by making friends with them. Travelling overseas can also be of great help for becoming familiar with the international language.

It is believed by many people that learning a different language is not easy. There are numerous factors that increase the difficulty of acquiring a foreign language, and this essay will discuss a couple of them and present some effective ways to learn a new language.

To begin with, a number of things can make learning another language difficult, and the primary ones are a lack of cultural knowledge and personality. With regard to the former, as its speakers’ culture and lifestyle are all inextricably bound up in one language, it is not possible to master it without an understanding of its culture. A good example of this can be seen in the case that many English speakers make a mistake with having conversation in Korean, where a variety of respective expressions are developed. Those who do not use respective words to the elderly, are sometimes considered to be very rude. As for personality, those with an outgoing character are usually likely to communicate more fluently than introvert people. As they put more emphasis on fluency than accuracy, which results in getting more chances to practice the language, consequently leading to a faster learning.

To combat this trouble, two solutions can be suggested to improve proficiency of a foreign language. Above all, one’s target language’s culture should be assimilated. This is because language can be acquired better through understanding its speakers’ way of thought, custom and even history, not to mention its linguistic properties. This can be easily achieved through books, movies, and internet blogs. On top of that, it is necessary to lessen worries about making mistakes. For this, not only are individual efforts inevitable, but also language instructors ought to create a relaxing learning atmosphere, so that learners can practice regardless of mistakes. All these can have a long-lasting effect on improving one’s language ability.

To conclude, a lack of cultural background knowledge and personal learning style are mainly responsible for the difficulty in learning a foreign language. Along with individual learners’ understanding of the target culture, language tutors’ efforts for comfortable learning atmosphere can be effectively implemented to overcome the problem.

Sample 1:

The issue of addressing the global challenge of feeding a rapidly expanding population has spurred discussions about potential solutions, including the adoption of Genetically Modified (GM) foods. While some proponents argue that GM foods present a viable answer to this problem, I fundamentally disagree. The potential risks associated with GM foods and the availability of alternative sustainable approaches make me skeptical about their efficacy as a long-term solution.

To begin with, Genetically Modified foods often involve the manipulation of organisms' genetic makeup to enhance desirable traits, such as increased crop yield or resistance to pests. While this may seem promising in theory, the unintended consequences of genetic modification could pose significant risks to human health and the environment. For instance, allergens or toxins could be inadvertently introduced into GM crops, leading to adverse effects on consumers. The release of genetically modified organisms into the environment could also disrupt natural ecosystems and harm biodiversity.

Additionally, the push for GM foods detracts attention and resources from more sustainable and holistic agricultural practices that have the potential to address food security challenges without compromising safety. Agroecological approaches, such as crop rotation, agroforestry, and integrated pest management, offer environmentally friendly alternatives to intensive monocultures and chemical-based farming. These methods promote soil health, water conservation, and biodiversity, all of which are crucial for ensuring the long-term sustainability of food production.

In conclusion, while the growing global population necessitates innovative solutions for food security, I am opposed to the idea that GM foods offer a viable remedy. The potential risks to human health and the environment, coupled with the availability of more sustainable agricultural practices, make me doubtful about the long-term efficacy of genetically modified foods. Instead of relying solely on GM foods, it is imperative to explore diverse and sustainable approaches that prioritize both human well-being and the planet's health.

Sample 2:

To tackle food shortages, many scientists recommend genetically modified (GM) food as a solution. Despite some concerns regarding this solution, I strongly believe that this is the future for food security.

The first benefit that GM foods offer is that it has significantly higher yield compared to traditional crops. GM foods have their genes altered to reproduce their cells quicker, leading to faster crop productions. Also, GM foods are capable of withstanding harsh environments, such as during winters and dry summers. Another benefit of consuming more GM foods is that they require fewer pesticides, contrary to popular belief. Because scientists design GM foods to be resistant to common pests, farmers do not need to spray pesticides as regularly as they would growing traditional crops.

However, despite these benefits, there are some concerns that researchers should revisit before populating GM foods. The first concern is the impact GM crops have on the ecosystem. Because these crops are known to be resistant to pests, it could lead to the eradication of pest species. As a result, this can disrupt the ecosystem’s balance. The second concern is that, due to GM crops’ high efficiency and rapid growth, they can easily become an invasive species with unhealthy farming practices. This problem, aside from damaging the ecosystem, also has adverse effects on the economy. For example, if one plot destined to grow a certain plant gets invaded by another species, farmers will experience a loss of income.  

In conclusion, although admittedly, there are some legitimate concerns for GM foods, I still strongly agree that GM crops are the most feasible solution to the global food shortage.  

Sample 3:

Feeding the ever-growing world population is undoubtedly a significant challenge that needs to be addressed. Some individuals argue that genetically modified (GM) foods could provide a viable solution to this problem. In my opinion, while GM foods may offer certain benefits, they also come with potential risks and drawbacks that need to be carefully considered.

Proponents of GM foods argue that they can help increase crop yields, improve nutritional content, and enhance resistance to pests and diseases. This, they claim, would enable farmers to produce more food on less land, ultimately helping to feed a larger population. Additionally, GM foods have the potential to withstand harsh environmental conditions, such as drought or extreme temperatures, making them more resilient and reliable sources of food.

However, it is important to acknowledge the concerns surrounding GM foods. Critics argue that the long-term health and environmental impacts of consuming and cultivating GM crops are not yet fully understood. There are also ethical considerations, such as the potential for corporate control over the food supply and the loss of biodiversity. Furthermore, the introduction of GM crops into natural ecosystems could have unforeseen consequences, disrupting delicate ecological balances.

In conclusion, while GM foods may offer some potential benefits in addressing the challenge of feeding a growing world population, the risks and uncertainties associated with their widespread adoption cannot be ignored. It is crucial to conduct thorough research and risk assessments to ensure that the benefits outweigh the potential drawbacks. Ultimately, a balanced approach that takes into account the needs of both current and future generations is necessary to tackle this pressing issue.

Sample 4:

Whether GM foods are the ultimate answer to address the need to feed the ever-growing global population has been a topic of fierce argument recently among intellectuals across the world. However, I fully agree with the statement that such foods are an effective remedy to worldwide food scarcity.

One obvious advantage of GM foods is better production in lesser time which will ensure food for more people that too utilizing a few resources. In addition, these foods and their cultivation are a lot more environmentally-friendly than normal foods because the former are highly resilient to diseases, pests and insects which reduces the need to use harmful herbicides, pesticides, insecticides and so on. This also ensures that people get pure fruits and grains, for example, free from chemicals.

Better texture, varied flavors and improved nutritional values are some other qualities which make genetically modified foods a viable solution to shortage of food. When such high-quality foods are made available at cheaper prices, it will sure save governments and individuals substantial sums of money, not to mention the obvious health benefits for people. Further, longer shelf-life makes bioengineered foods easier to transport to distant places and store them. Last but not least, their potentially non-allergenic nature makes them Manna from heaven for the hungry millions.

In short, GM foods are the need of the hour. Therefore, the authorities across the world need to spring to action to mass-produce genetically-engineered foods and make them available to people thereby saving hundreds of thousands of lives from malnutrition and starvation.

Sample 5:

As the population is increasing at a fast rate across the world, a shortage of food is becoming a perplexing problem. Some individuals suggest that this can be addressed by genetically modified foods. In my opinion, I totally disagree with the statement since engineering genetic foods have a high risk of potential problems and negative environmental impacts.

The main issue of genetic modification organism is a risk of potential problems after having the food for a long-term. This is because scientists or nutritionists are not sure about the long-term effects and safety as it is a relatively new practice. For example, food allergic reactions have risen in the last decade such as nuts or dairy products, which resulted from consuming GM foods. In addition, there are also a large number of people who hold concerns about the potential risks to human health affected by GM crops such as inducing mutations in human genes. Therefore, numerous people have an inclination toward eating organic food rather than GM foods.

Another thing to consider is that the agricultural method of GMOs brings harmful effects on the environment and ecosystem. Firstly, the changes in the agricultural practice affect on the farming and where weeds or other harmful factors become stronger. This results in overuse of the toxic sprays such as pesticides and herbicides. Secondly, the new cultivation method is harmful for non-GMO crops and also insects or animals, which can lead to loss of biodiversity. To illustrate this, bees play an important role in the pollination of various food crops, but they are vulnerable from the sprays.

In conclusion, I am strongly opposed to the opinion that genetically modified foods can deal with

a shortage of food due to the world demographic growth. This is for the reason that it has potential problems affecting people’s health and it has negative effects on environmental impacts and biodiversity.

Sample 1:

Distance learning through an online platform is provided for students as an option to replace traditional classroom at many universities. In my view, such a development, although detrimental at some point, could be seen as an essential step forward.

On the one hand, this way of learning remotely without being in regular face-to-face contact with teachers in the classroom is negative in two aspects. First, online students cannot develop comprehensively like the way other students who attend classes at school do. During online courses, students can barely make friends or even compete with their peers. This is often linked to the fact that those learners seem to undervalue the significance of interaction and rivalry with classmates in an educational environment which, actually, are great stimuli for scholastic success. Second, participants of online learning programs tend to procrastinate and poorly allot appropriate amounts of time to complete assignments. This form of studying requires tremendous self-discipline as well as organization and time management skills while students usually struggle with balancing their coursework other priorities and easily get demotivated without direct guidance from instructors.

On the other hand, online learning proves to be a great alternative although traditional universities are still widely considered as the best way to acquire knowledge and a diploma. Access to all resources of a traditional course is offered, which empowers learners to freely choose a wide range of different subjects, from science to economics. Furthermore, lower costs and the widespread presence of the Internet allow unlimited numbers of participants regardless of not only their financial background but also current living places. For example, Coursera is a website that offers a variety of courses at reasonable prices and presents legal degrees for participants upon completion of each course.

In conclusion, though there are some drawbacks of courses delivered on websites, I believe the aforementioned online studying method is revolutionary in contemporary tertiary education systems.

Sample 2:

The growing trend of universities offering online courses as an alternative to traditional classes has sparked debate on whether this is positive or not. While some consider it as a revolutionary step forward in accessibility and flexibility, others express concerns about its ability to eliminate the irreplaceable value of traditional classes. In my opinion, while the rise of online education presents double-edged implications, it is a largely positive progression.

On the one hand, online learning presents potential drawbacks. One inevitable disadvantage of these courses is that the absence of face-to-face interaction can hinder the development of critical thinking and communication skills, both of which are crucial for learners. Online platforms may also struggle to encourage the dynamic exchange of ideas that thrives in a physical classroom setting. Additionally, the absence of structured supervision and peer interaction can lead to issues such as lack of motivation, self-discipline, and time management for some students.

On the other hand, I contend that online courses offer superior advantages. They eliminate distance between students and teachers, allowing individuals from remote locations to pursue higher education. This is particularly beneficial to those who face financial and geographical constraints in attending an offline class. Another benefit is that the self-paced nature of many online courses enables flexible learning, catering to different learning styles and maximizing individual potential. Furthermore, online education can be more cost-effective for universities, reducing infrastructure and operational expenses. This can potentially translate into lower tuition fees or increased scholarship opportunities for students.

In conclusion, the rising popularity of online education presents a multifaceted challenge for universities. While there are potential drawbacks related to social interaction and self-discipline, I believe that the various benefits in terms of accessibility, flexibility, and cost-effectiveness make online learning a positive development in current life.

Sample 3:

The idea of providing distance education by numerous universities has become quite fashionable. Whilst I believe online courses to have great benefits in several cases, I presume that this trend may give rise to some downsides.

On the one hand, I believe that this tendency is likely to be profitable. One noticeable advantage is an increase in academic chances for social members. The adoption of video-conferencing technologies and free-to-use group chats in Internet-based courses may serve to facilitate the study of busy workers without leaving their current jobs. Furthermore, students can get access to academic lectures by prominent professors from world-famous universities via e-learning classes. Another point in favour of is convenience. Online distance education enables students to not only take the initiative to plan their study schedule but also review lectures, discussions, comments or share notes on demand.

On the other hand, there appear to be potential shortcomings stemming from this trend. One disadvantage is the lack of interaction with the instructor and fellow classmates in the light of the internet disconnect. This procrastination may discourage learners from meeting their deadlines and completing their assignments. Students’ plagiarism and dishonesty are areas of concern as well. Some critics feel that it is easier to plagiarize or share answers owing to reduced surveillance and increased connectivity. Consequently, this copyright infringement could drive them to the verge of being expelled from the course of study.

Overall, based on what has been discussed above, it seems to me that learning activities through the medium of the internet have both favourable and adverse effects.

Sample 4:

Several tertiary educations indeed provide opportunities for students to get involved in online courses as a replacement for offline courses. In this essay, I am going to pinpoint the advantages and shortcomings associated with online learning at college.

On the one hand, there are some demerits related to online platform classrooms. First and foremost, there is a lack of face-to-face interaction between students and teachers. In fact, online courses rely on virtual communication systems; as a result, learners cannot show vivid facial expressions or body language as compared to traditional classes. Hence, they feel sleepy and exhausted due to sitting in front of a screen for hours, leading to not concentrating on the lessons. Another shortcoming is that online classes limit practical experiences. For example, medical university students are required to absorb a wide range of theories and put them into practice. Due to online courses, they cannot carry out the experiments in the labs as well as in the operating theatres.

On the other hand, although this trend has numerous disadvantages as mentioned above, I strongly believe that the advantages are more dominant. Firstly, online courses can make education more accessible to individuals. For instance, during the COVID-19 pandemic, all schoolers are unable to go to school for a long time, thus some virtual classes such as Zoom meetings, Google Meet, Teams, and so on have come up to support students can continue gaining knowledge as class delivered on campus. Secondly, online education can also be cost-effective. By eliminating expenses related to accommodation and commuting, students save an amount of expenditure each month. Moreover, some websites offer a variety of reasonable prices and legal certificates, like Coursera, for participants.

In conclusion, while the proliferation of online courses offered by universities presents both positive and negative aspects, the benefits of this alternative mode of education outweigh the drawbacks. 

Sample 5:

In recent years, the advent of online courses as an alternative to traditional on-campus classes has sparked debates about the impact of this transformation on education. From my perspective, this shift is undeniably a positive development, bringing forth numerous advantages.

One key advantage of distant learning is the introduction of interactive learning. Online courses leverage forums, virtual discussions, and collaborative projects to foster engagement among students. This not only enriches the learning environment but also creates a dynamic digital experience, transcending the limitations of a physical classroom. For example, Kahoot, an interactive learning platform, allows students to participate in quizzes and games in real-time, turning the educational experience into an engaging and enjoyable competition.

Moreover, online courses facilitate the development of practical skills. Through collaborative projects, students can enhance teamwork and communication skills, preparing them for the demands of the professional world. Additionally, the integration of digital tools in online learning equips students with technological proficiency, a crucial aspect in today's technology-driven society.

Online courses also champion the cause of independent learning. By allowing students to tailor their study schedules to their pace and preferences, these courses empower individuals to take control of their education. This flexibility is especially beneficial for those with diverse learning styles and commitments beyond academia. For instance, a working professional pursuing an online MBA can seamlessly integrate coursework into their busy schedule, balancing career responsibilities with educational pursuits.

In conclusion, the integration of online courses offers a harmonious blend. It not only embraces the advantages of interactive learning, practical skills development, and independent learning but also reflects the evolving needs of students in a technologically advanced era.

Sample 6:

Education - specifically tertiary one - has long been a matter of public concern for its profound impacts on people’s lives. Being provided with various technological breakthroughs, universities around the world have come up with the idea of granting students to take part in a new form of course, distant learning courses in particular. In my point of view, this newborn type of education will bring both benefits and detriments to both participating undergraduates as well as the society in general.

There is no denying that having the ability to learn over a far distance is beneficial in many ways. To commence with, learners can enjoy obtaining knowledge at their convenience, whenever or however they feel like since online courses can provide them with valuable lectures over the Internet. One simply just has to schedule their study time in accordance with their daily timetable, not the other way around, which is very likely to be suitable for nowadays fast-paced, flexible lifestyle. Moreover, online courses participants do not have to commute to their classrooms at all, but instead turning any room in their house into one, as long as electronic devices are present. Society, in addition, will thank this contemporary approach for saving a variety of unnecessary cost namely travel, facility and other anonymous ones, thus benefiting the economy as a whole.

On the other hand, there remain several obvious hassles to this advanced method. Highly promising as it seems, but learning process will never be integral, not without a true face-to-face communication between lecturers and lecturees. There will always be questions that need answering during the lectures, and with online courses there has not been any really efficient solution to this problem. Another point worth considering is the proliferation of unqualified alternative courses, which offer no real help apart from fraud lessons to scam money from learners, thus hindering the country’s development.

In conclusion, although over-the-Internet courses can provide people with ample blessings, their limitations should never be overlooked. One should implement suitable curriculum to yield best results and hamper such disadvantages.

Sample 7:

The advent of widespread internet access has made it possible for students to study online as opposed to face-to-face in a traditional university setting. While this option brings with it attractive benefits, it also has some potential drawbacks that must be kept in mind.

The appeal of studying via one’s internet connection is that it is flexible. In the modern world, many people are forced to juggle their studies with work, which means they are often not free to attend classes during daytime hours. By being able to study at their leisure, they can advance their education without suffering in other areas. Moreover, the worldwide coverage of the internet means that people who do not live within the vicinity of a university can also access vital educational resources which can make a massive difference in their lives and the lives of those in their communities.

On the other hand, the benefit of university extends further than being able to learn directly from a lecturer. College campuses are places where young people can develop their teamwork and group skills, while also being the place where people establish relationships that will help them find jobs and be successful in their future careers. As the old saying goes – “It’s not what you know. It’s who you know.”

Overall, the existence of online studying provides an exciting opportunity for people to learn who would otherwise not be able to. Nevertheless, it must be remembered that the advantages of attending a university campus reach far beyond the academic knowledge that one learns there.
