Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question.  The Urban Gardener Cities are home to skyscrapers and apartment buildings, and it's rare to find wide, open spaces within them. With limited space for parks and gardens, architects and city planners often find it challenging to incorporate greenery into neighbourhoods.  One creative solution is to grow plants on unused areas like walls or rooftops. It's a popular idea, and now rooftop gardens and green walls have been spouting up in cities around the world. There are many benefits to having green spaces to the urban landscape. Adding gardens to rooftops or walls can create a pleasant environment - what was once a grey cement wall can become a colourful, blooming garden. The CaxiaForum art gallery in Madrid, Spain, is a famous example - one of its walls is covered with 15,000 plants from over 250 different species.  In other cities, green walls are being used more functionally, to cover up construction sites and empty buildings and to prominently decorate the lobbies of office buildings. Using plants to cover walls and rooftops can also keep cities cooler in the summer. Buildings and roads absorb the sun's heat and hold it, causing a building or neighbourhood to stay warmer longer. Plants, on the other hand, provide an enormous amount of shade. There is evidence that growing a roof or wall garden can lowe Many cities offer tax discounts to businesses with these features.  In New York City, public schools plant rooftop gardens that can reduce heating and cooling costs. In addition to saving the school money, teachers and parents love the gardens because of their educational value - it's a fun and healthy way for their kids to investigate the world around them. “For the children, it's exciting when you grow something edible," said Lauren Fontana, principal of a New York public school.  These green spaces are also used to grow food. In recent years, rooftop gardens have slowly been included in the "local food movement". This is based on the concept that locally grown food reduces pollution since it does not have to be transported far. Vegetables are being grown in rooftop gardens by schools, churches, neighbourhoods and even restaurants. Chef Rick Bayless serves “Rooftop Salsa” at his restaurant in Chicago, USA, using only ingredients grown in his rooftop garden. Rooftop gardens and green walls may require a bit more effort to grow and maintain. However, hard work always brings rewards, and with green spaces, the rewards are plentiful.    What is this passage mainly about?

Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question.  REALITY TELEVISION Reality television is a genre of television programming which, (it is claimed), presents an unscripted dramatic or humorous situation, documents actual events, and features ordinary rather than professional actors. It could be described as a form of artificial or "heightened" documentary. Although the genre has existed in some form or another since the early years of television, the current explosion of popularity dates from around 2000.  Reality television covers a wide range of television programming formats, from game or quiz shows which resemble the frantic, often demeaning programmes produced in Japan in the 1980s and 1990s (a modern example is Gaki no Tsukai), to surveillance-or voyeurism-focused productions such as Big Brother.  Critics say that the term "reality television” is somewhat of a misnomer and that such shows frequently portray a modifies and highly influenced form of reality, with participants put in exotic location or abnormal situations, sometimes coached to act in certain ways by off-screen handlers, and with events on screen manipulated through editing and other post-production techniques.  Part of reality television's appeal is due to its ability to place ordinary people in extraordinary situations, For example, on the ABC show, The Bachelor, an eligible male dates a dozen women simultaneously, traveling on extraordinary dates to scenic locales. Reality television also has the potential to turn its participants into national celebrities, outwardly in talent and performance programs such as Pop Idol, though frequently Survivor and Big Brother participants also reach some degree of celebrity.  Some commentators have said that the name “reality television" is an inaccurate description for several styles of program included in the genre. In competition-based programs such as Big Brother and Survivor, and other special-living-environment shows like The Real World, the producers design the format of the show and control the day-to-day activities and the environment, creating a completely fabricated world in which the competition plays out. Producers specifically select the participants, and use carefully designed scenarios, challenges, events, and settings to encourage particular behaviours and conflicts. Mark Burnett, creator of Survivor and other reality shows, has agreed with this assessment, and avoids the word “reality" to describe his shows; he has said, "I tell good stories. It really is not reality TV. It really is unscripted drama."   In the first line, the writer says "it is claimed” because __________

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.      Have you ever entered a tropical rainforest? It’s a special, dark place completely different from anywhere else. A rainforest is a place where the trees grow very tall. Millions of kinds of animals, insects, and plants live in the rainforest. It is hot and humid in a rainforest. It rains a lot in the rainforest, but sometimes you don’t know it’s raining. The trees grow so closely together that rain doesn’t always reach the ground.        Rainforests make up only a small part of the Earth’s surface, about six percent. They are found in tropical parts of the world. The largest rainforest in the world is the Amazon in South America. The Amazon covers 1.2 billion acres, or almost five million square kilometers. The second largest rainforest is in Western Africa. There are also rainforests in Central America, Southeast Asia, Northeastern Australia, and the Pacific Islands.        Rainforests provide us with many things. In fact, the Amazon Rainforest is called the “lungs of our planet” because it produces twenty percent of the world’s oxygen. One fifth of the world’s fresh water is also found in the Amazon Rainforest. Furthermore, one half of the world’s species of animals, plants, and insects live in the Earth’s rainforests. Eighty percent of the food we eat first grew in the rainforest. For example, pineapples, bananas, tomatoes, corn, potatoes, chocolate, coffee, and sugar all came from rainforests. Twenty-five percent of the drugs we take when we are sick are made of plants that grow only in rainforests. Some of these drugs are even used to fight and cure cancer. With all the good things we get from rainforests, it’s surprising to find that we are destroying our rainforests. In fact, 1.5 acres, or 6,000 square meters, of rainforest disappear every second. The forests are being cut down to make fields for cows, to harvest the plants, and to clear land for farms. Along with losing countless valuable species, the destruction of rainforests creates many problems worldwide. Destruction of rainforests results in more pollution, less rain, and less oxygen for the world. (Adapted from Reading Challenge 2 by Casey Malarcher and Andrea Janzen) Câu 36.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.     In the early 1800s, less than 3% of the world's population lived in cities; today, more than half of the global population is urban and by 2050, the proportion will rise to three quarters. There are thousands of small and medium-sized cities along with more than 30 megacities and sprawling, networked metropolitan areas — conurbations — with 15 million residents or more. Yet despite these massive transformations in how people live and interact, our international affairs are still largely dictated by nation states, not cities.     Cities are beginning to flex their muscles on the international stage. They are already displacing nation states as the central nodes of the global economy, generating close to 80% of global GDP. Cities like New York and Tokyo are bigger in GDP terms than many G-20 countries.     Metropolitan regions and special economic zones are linking global cities through transnational supply chains. A growing number of mega-regions, such as those linking cities in Mexico and the US, transcend borders. In the process, cities are collectively forging common regional plans, trading partnerships, and infrastructure corridors. The spectacular rise of cities did not happen by accident. Cities channel creativity, connect human capital, and when well governed, they drive growth. That many cities and their residents are rolling up their sleeves and getting things done — where nations have failed — are grounds for optimism. In the future, we hope that it is our proximate, accountable, and empowered city leaders who will define our fates. Câu 31. What is the passage mainly about?
