The diagram below shows how one type of coal is used to produce electricity. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words. (ảnh 1)

Sample 1:

The provided diagram illustrates how electricity is generated from coal.

Overall, the process includes several key stages, beginning with coal mining and culminating in power delivery to households and industries, with waste heat being a by-product at various stages.

The first step involves coal being mined at extraction plants. The mined coal subsequently undergoes crushing, breaking it down into finer pieces. These crushed coal fragments are then transported to a gasifier, inside which combustion occurs at elevated temperatures in order to convert the coal into gas.

After this phase is complete, the produced gas proceeds to a separate facility for cooling, with excess heat released as waste. Once cooled, the gas undergoes a cleaning stage whereby any impurities are removed. The purified gas then becomes the input for a gas power plant. Within the power plant, electricity is generated and distributed for domestic and industrial use. It is worth noting that even at this final stage, additional waste heat is still discharged as a by-product.

Sample 2:

The illustration demonstrates the generation of electricity by utilizing a particular type of coal. Overall, there are eight steps in the production, beginning with mining the coal, followed by various processes to the raw material, and ending with distributing the electricity to final uses.

The first five steps involve the conversion of coal into gas, which begins with coal being excavated from a mining plant. After that, it goes through a crushing machine and is delivered by trucks to another factory, where a gasification process transforms the crushed coal into gas. Subsequently, another facility is responsible for lowering the temperature of the gas and releasing the waste heat.

The remaining steps produce electricity. Cool gas is transported to another unit for cleaning and then becomes the input for a gas power plant. While electricity is generated, excessive heat is released as a source of waste. Finally, the electricity produced from the power plant is supplied for both household and industrial uses.

Sample 3:

The diagram illustrates the process of generating electricity from a particular kind of coal.

Overall, this process comprises multiple steps occurring at different facilities: starting from the mining of the coal to the production of gas, and eventually the generation of electrical power used for various purposes.

To begin with, coal is extracted from a mine, after which it is ground down by a crusher. The pulverized coal is then put into a mine cart before being loaded onto a truck for transportation. Once this material has been transported to the factory, it is heated to produce gas.

The process continues with the gas being sent to a separate facility, in which it is cooled while waste heat is discharged. After the cooling process is complete, the gas will be directed to a facility where it is purified. It is thereafter transferred once again to a power plant which uses the gas to generate electricity and expel any excess heat waste. Finally, the electricity produced is distributed via transmission lines to homes and industries.

Sample 4:

The drawing demonstrates how electricity is generated from a type of coal.

Overall, it can be seen that there are eight stages included in this procedure, commencing with the extraction of coal and completing with production of electricity. Also, the process takes place at a coal mine and several treatment facilities.

In the initial stage, coal is collected from coal mines. After undergoing a crushing stage, the coal is transported by trucks to a gasifier. This is where high temperatures are introduced, and the pulverized coal is heated and turned into gas, ready for the next steps.

The subsequent stage involves gas being delivered to a cooling plant from the gasifier. Following this, some of this gas is transported to another factory for cleaning, while waste heat is disposed of. After being cleaned, the gas is moved to a power plant to be converted into electricity. Finally, the generated electricity is distributed to households and factories, with waste heat being removed.

Sample 5:

The diagram illustrates how to generate electricity from coal.

Overall, the process comprises several stages, starting with the mining and crushing of coal, followed by the heating and cleaning of gas, and culminating in the generation and allocation of electricity.

At the start of the process, coal is extracted from a mine before being transported to a crusher, where it is broken down into smaller pieces in order to burn more efficiently. The coal lumps are then subjected to high temperatures in a gasifier, triggering a combustion reaction as gas and other by-products are produced. Subsequently, the gas is cooled down while the waste heat is released.

The process continues with the gas being cleansed to remove impurities, after which it is pumped into a gas power plant where electricity is generated. During this stage, more waste heat is discharged into the atmosphere. Finally, electricity is distributed to various households and industries.

Sample 6:

The diagram illustrates the various steps involved in the production of electricity from coal.

Overall, the procedure consists of six primary steps, beginning with the extraction of coal from mine and culminating in the distribution of electricity to the grid.

The process initiates at a coal mine, where coal is extracted and then transported to a crusher to be pulverized into small pieces. Following this, the crushed coal is conveyed to gasifiers, where it undergoes heating to transform into gas, followed by a cooling phase. During this phase, the waste heat generated in the gasifier can be later extracted and managed.

Once gasified, the coal-derived gas is cleaned to remove impurities, rendering it suitable for efficient power generation. The purified gas is then directed into a gas power plant where it fuels turbines to produce electricity. Finally, this resulting electricity is distributed to the grid and for consumer use.

Sample 7:

The given picture illustrates how a certain type of coal is used to generate electricity. Overall, there are three main stages in this process. It starts with the extraction of coal, continues with processing this material to generate electricity and culminates with distributing electricity to various locations for household and industrial purposes.

Regarding the material preparation stage, a specific type of coal is mined from coal mines using specialised equipment. It is then ground by crushers and dumped into crates. Finally, the crushed coal is delivered by trucks to thermal power plants.

Concerning the production and delivery stages, the coal received at the plant is first gasified using heat. The gas produced is subsequently pumped into a cooling system where waste heat is released. The following step involves cleaning the gas to remove any impurities before it is utilised to produce electricity in a power plant. At this plant, another volume of waste heat is also released, and the electricity is finally distributed to households for domestic use or to industrial areas.

Sample 8:

The diagram delineates the sequential stages involved in generating electricity from coal.

Overall, the process encompasses six primary stages, commencing with coal extraction from mine and concluding with electricity transmission to the grid.

The procedure starts by excavating coal from mines, followed by transportation to a crusher for pulverization into small fragments. Subsequently, the crushed coal is conveyed to gasifiers, where it undergoes heating to convert into gas before a cooling phase. Throughout this phase, the residual heat generated in the gasifier can be harnessed and managed.

Following gasification, the coal-derived gas goes through purification to eliminate impurities, ensuring optimal efficiency in power generation. The refined gas is then channeled into a gas power plant where it drives turbines to generate electricity. Ultimately, the produced electricity is distributed to the grid and made available for consumer use.

Sample 9:

The diagram illustrates the sequential phases involved in harnessing electricity from a specific type of coal.

To commence with, the coal extraction process begins with mining deep underground, followed by crushing to facilitate combustion. Following this initial phase, the crushed coal is transported via lorry to the factory, where it is introduced into a gasifier for combustion, transforming coal into raw syngas. Subsequently, after the syngas undergoes cooling, eliminating excess heat, it undergoes a purification process to remove impurities and pollutants, including carbon dioxide, mercury, and sulfur, ensuring minimal environmental impact. The purified gas is then utilized to drive a gas turbine within a power plant, generating electricity while waste heat is efficiently managed. Ultimately, the electricity generated is distributed across residential and industrial sectors through the national grid.

Overall, the process of generating electricity from coal involves several crucial stages, starting from coal mining and culminating in electricity distribution. This method boasts environmental friendliness by minimizing harmful emissions into the atmosphere.

The plans below show a bookstore in 2000 and the bookstore now.  Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words. (ảnh 1)

Sample 1:

The maps show changes in the layout of a bookstore between 2000 and the present. 

In general, the layout of the bookstore has been significantly changed, especially on the left-hand side of the room. A number of features have been moved and modified, while other facilities have been added. 

In 2000, there was a large section dedicated to fiction books on the left-hand side of the store. However, that section has been divided into four new sections, in which books on art, hobbies, cookery, and fiction are now displayed.

The area for fiction books in the rear left corner of the store is now used for non-fiction books, while the old non-fiction section has been transformed into a new cafe. The central area of the room, which used to be for art, cookery, and hobby books, is now occupied by tables and chairs. Meanwhile, the space for travel books, new books, and the service desk, has remained unchanged over the years. 

Sample 2:

The maps depict the layout changes of a bookstore from 2000 to the present. Overall, the bookstore has undergone significant modifications, including the relocation of several book sections, the introduction of a seating area, and the addition of a café.

In 2000, the bookstore’s central area was occupied by the art, hobbies, and cookery sections. These sections have now been moved to the top left corner, next to the fiction area. As a result, the fiction section, which previously spanned across two large areas, has been reduced in size. The central space, once home to art, hobbies, and cookery, now accommodates three tables for customers to sit and read.

Additionally, the non-fiction section, originally located at the bottom of the store, has been relocated to the top right corner, where the larger fiction area once stood. The space formerly used for non-fiction has been transformed into a café, providing customers with refreshments. Despite these transformations, some areas have remained unchanged. The travel section, new books, service desk, and entrance have all stayed in their original positions throughout the period.

Sample 3:

The two maps depict the transformation of a bookshop over the course of two decades, from the year 2000 to the present.

Overall, the layout of the store has undergone significant changes over time, particularly with regard to the arrangement of the different sections. While the centre of the store is now fully occupied, the relocation of the cooking, hobbies, and art units to the north has resulted in a more balanced distribution of content throughout the store. The addition of a café has also enhanced the shopping experience for customers, offering a comfortable space for reading, relaxing, and enjoying a cup of coffee.

In the year 2000, the central area of the bookshop was primarily occupied by cooking, hobbies, and art units, while the northeast and north edges were dominated by large fiction units. The west and east west corners housed travel, new books, and a service desk, and a non-fiction section was situated on the east side of the store.

Fast forward to the present, and the bookshop has undergone a significant transformation. The central tables are now completely occupied, forcing the cooking, hobbies, and art units to be relocated to the north. The previous large fiction unit in the northeast corner has been replaced by a non-fiction section, and a café now occupies the south side of the store, where the non-fiction department once stood.

Sample 4:

The two maps show the evolution of a bookshop from the year 2000 to the present. Overall, the tables in the centre have been totally occupied, pushing the units for hobbies, literature, and cooking to the north. Also, a café has replaced a non-fiction section in the present bookstore.

The centre of the bookshop included cooking, hobbies, and art areas in 2000. Large fiction units were occupying the northeast and north edges. After the entry area, on the west and east west corners were travel, new books, and a service desk. A non-fiction section was also located on the east side of the bookstore.

The present bookshop has three attached circular tables with four chairs surrounding each one in the centre, displacing the cooking, hobbies, and art units to the north side where there used to be a huge fiction arrangement. Additionally, a non-fiction section has taken the place of the other fiction unit that was in the northeast corner. In fact, the south side of the bookshop, which is currently home to a café, used to house the nonfiction department.

Sample 5:

The two maps depict the changes that have taken place in a bookstore from 2000 to the present day. Overall, the central area has been completely packed with tables, pushing cookery, hobbies, and fiction units on the north side. Meanwhile, at the expense of a non-fiction unit, a café has appeared in the current bookstore.

In 2000, there were cookery, hobbies, and art sections at the centre of the bookstore. Both the north and the northeast sides were occupied by large fiction units. Travel, new books, and service desk were on the west and east west corner right after the entrance area. Moreover, there was a non-fiction unit on the east side of the bookstore.

In the current bookstore, pushing cookery, hobbies, and art units to the north side, where previously there was a large fiction setup, the central space is packed with three round tables attached with four seats around each one. Furthermore, the other fiction unit, which was located at the northeast corner, is now replaced with a non-fiction area. In fact, the nonfiction section was previously on the south side of the bookstore, which is now occupied by a café.

Sample 6:

The maps below show a bookstore in 2000 and now.

Overall, several scattering book sections have been consolidated to make space for the introduction of some new services.

In 2000, fiction was the most dominating genre, occupying the largest L-shaped shelves running along the top wall and half of the right-side one. Hobbies, cookery, and art took up a modest space in the middle of the bookstore.

Currently, the area right after the entrance has been kept intact with space dedicated to the travel and new book sections. The L-shaped area has been divided into four nearly equal sections to accommodate art, cookery, and fiction at the top, and non-fiction on the right, which has allowed the removal of the four separate display areas. The non-fiction section from 2000 has been removed to establish a café, enhancing customers' experience.

Sample 7:

The maps illustrate the reorganization of a bookstore at present in comparison to its arrangement in 2000.

According to the floor plan of the store, the area right at the entrance has been kept intact with space dedicated to the travel and new books sections. Also, in the near right-hand corner after the front entrance, still stands the service desk.

However, after reshuffling, the fiction section stretching along the left wall in 2000 has been reduced to only a quarter of its original size in the back corner of the store. This leaves room for the art, hobbies, and cookery sections which have been removed from the middle of the store to make way for three sets of tables and chairs. At the back of the store, people now keep non-fiction books where there used to be fictions. Meanwhile the non-fiction section in 2000 has been removed to establish a café which customers can reach when they walk past the service desk on the right of the store.

Overall, the maps demonstrate the resizing and relocation of the same sections of books in the store to accommodate a new in-house café.

Sample 8:

The map illustrates the evolution of a bookstore's layout from the year 2000 to the present day. A comparative analysis reveals a significant reconfiguration of various sections, notably a reduction in the area allocated to fiction, which has been supplanted by new facilities and sections.

Commencing with the left side of the entrance, the original fiction area has undergone a notable transformation, segmenting into four distinct categories: Art, Hobbies, Cookery, and Fiction. This diversification enhances the variety available to customers. Furthermore, the upper right section, which initially housed a dedicated fiction area, has now been occupied by a Non-Fiction section. In contrast, the Travel section, located directly opposite the entrance, has remained unchanged over the years, indicating a stable demand for this genre.

On the right side of the entrance, the sections for New Books and the Service Desk have retained their original positions. However, a Non-Fiction area that existed in 2000 has been converted into a café, reflecting a shift towards a more leisure-oriented experience for patrons. Additionally, the middle section, which previously included Cookery, Hobbies, and Art areas, has transitioned into a cluster of tables, providing customers with spaces to sit, relax, or read while enjoying their visit to the bookstore.

Sample 9:

The changes which occurred to the physical layout of a bookstore since 2000 are portrayed in the given maps. Overall, it is clear that there have been done significant alterations in the store for the introduction of a Cafe and a reading area.

In 2000, the bookstore was a square-shaped building with its entrance at the West. The service desk was there towards its extreme right, crossing the sections for travel and new books. Most area of the store was occupied by books on fiction: at the North and towards the North-east. Non-fiction books were arranged to the South, towards the East of the service desk. At the centre, there were books on cookery, hobbies and art.

The first major change as a part of re-arrangement is seen at the centre, when the area is seen cleared up for reading. The area for fiction at North is seen shrunken by a quarter of its previous size. Books on art, cookery and hobbies occupied the other three portions. The area in the North-east, where fiction books were there in 2000, is seen occupied by non-fiction books now. At the place where the non-fiction books were seen, a café came to existence.

Sample 10:

The two maps illustrate the layout of a bookstore in 2000 and the present day.

Overall, while the core structure of the bookstore remains the same, there have been some noteworthy changes in the arrangement of bookshelves and the addition of a café and tables.

In 2000, the largest section in the bookstore was allocated to fiction books, located on both sides of the store. Non-fiction books occupied the space at the bottom right corner, while genres such as travel, art, hobbies, and cookery were arranged in the middle part of the store. A section labeled “new books” was placed near the entrance, along with a service desk on the left-hand side.

In contrast, the current layout has undergone several modifications. The fiction section has been reduced in size, and the space previously occupied by non-fiction books is now a café. The non-fiction section has been moved to the top right corner, replacing part of the old fiction area. In the center of the store, three tables have been introduced, creating a more communal space. Additionally, the sections for travel, art, hobbies, and cookery books have remained in the same area, but their positions have been slightly adjusted.

The line graph shows the number of people who used different communication services in the world.  Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words. (ảnh 1)

Sample 1:

The line graph gives data about the number of users of five different communication services worldwide from 1998 to 2008.

Overall, all services experienced some growth over the 10-year period, with cell phone and Internet services experiencing the most growth and becoming the most popular forms of communication.

In 1998, the figures for cell phone and Internet users started at around 5% of the population. They both increased over the remaining years, with cell phone service gaining the highest position in 2008, with more than 60% percent of the population using this type of service. This number was approximately three times as much as that of Internet service in the same year.

Meanwhile, throughout the 10-year period, little change was seen in the use of landline services, at about 15% of the population. Also, the use of mobile and fixed broadband services was minimal before 2002. The figures for these two services rose slightly to roughly 5% of the population by the last year.

Sample 2:

The line graph gives data about the number of users of 5 different communication services worldwide from 1998 to 2008.

Overall, cell phone and Internet services became more and more popular, and others similarly experienced minimal growth over the years.

In 1998, the figures for cell phone and Internet users started at around 5 per 100 inhabitants. They both increased over the remaining years, with cell phone service gaining the higher position in 2008, at more than 60 users per 100 in habitants. This number was approximately three times as much as that of Internet service in the same year.

Meanwhile, throughout this 10-year period, little change was seen in the use of the landline service, with about 15 users per 100 inhabitants. Also, mobile and fixed broadband had yet to be introduced by 2002. The figures for these two services rose slightly to roughly 5 users per 100 inhabitants in the last year.

Sample 3:

The line graph illustrates the number of people in the world who used five categories of communication services at two-year intervals from 1998 to 2008.

Overall, although all kinds of communication services tended to grow during the entire time period, only the increase in popularity in cellular phone service was significantly higher than the rise in that of other means of communication.

In 1998, the figure for cellular phone service was round about 500 people, as same as Internet service’s. From 1998, the number of individuals using cellular phone services increased dramatically to exactly 6000 people and became the most common means of communication in the year 2008. Additionally, the figure for Internet service was about five times higher than during the period of 10 years.

With 1500 people used, the figure for landline service was the highest number in 1998. However, that figure had a minor increase to 2000 people in 2006 before it dropped slightly to approximately 1800 people in 2008. The figure for mobile broadband and fixed broadband remained nearly 0 throughout the first six-year period. They were also the least popular kinds of communication services despite rising up to 500 people in 2008.
