A Case StudyDesertification around the Gobi Desert THE PROBLEMS The GOBI Desert, in the north of China, is now seven times bigger than Britain. China has large desert areas and much of its agricultural land is being threatened by desertification, which is getting worse. In addition, soil erosion has led to a huge loss of farmland and the drying up of rivers. Consequently, the livelihoods of 35 million people are being threatened. Furthermore it is even affecting cities. The nearest sand dune is less than 100 miles from Beijing, where unpleasant sandstorms are becoming more frequent. The worse the situation, the more pressure there is on the government to take action. The Causes The reasons for the changes are complex. It is clear that pollution of the air and water by factories is affecting the environment. Trees and other vegetation die, and so soil is eroded. The more trees that die, the less water is held in the earth. The need for wood for fuel and buildings leads to further deforestation, which causes further soil erosion. Local farmers find it more and more difficult to make a living. They end up using inefficient farming methods, which again leads to soil erosion. The Solutions The Government is carrying out anti-desertification projects, including the creation of a forest belt around deserts. The tree-planting campaign, known as the Great Green Wall, is meant to protect Beijing from sandstorms. China hopes to control the expansion of desert land by the year 2010 and plans to establish a protected eco-system in desert areas by 2050. 操作提示、通过题干后的下拉框选择题目的正确答案。 1.According to this passage, the Gobi desert is  {}.

GLOBAL FOOD “Mum, can we go to McDonald’s, please?” Some people might ask, “Where would we be today if we did not have fast food?” and “Where would parents take their children out to eat?’ It has been reported that approximately 30% of meals consumed by families in the USA are eaten at one of the big chains like Burger King and Taco Bell, though probably none is more famous than McDonald’s. The distinctive “golden arch” can now be seen in most major cities in the world. In 2002, McDonalds had approximately 25,000 restaurants in over 120 countries and served 29 million people a day. Apparently, the secret of their success is a marketing strategy of “think global, act local”. McDonald’s learnt that if they adapted their “Mac” meals to different cultures, it was more successful than having a standardized set of products that taste the same everywhere. So now, around 80% of McDonald’s restaurants are franchised to local people who serve food with a “local” flavor. For example, in Hong Kong, food called “Shake Shake Fries” and “Red Bean Sunday” can be found on the menu, while in Switzerland, “Vegi Macs” are served. However, fast food is not popular with everyone. It is often called “junk” food because it is said to be unhealthy and full of fat. Furthermore, many people claim that fast food chains produce enormous amounts of waste, while millions of people in developing countries go hungry. At the same time, more and more people no longer cook fresh food at home. “Convenience” food is just too convenient! It is so easy for people with busy working lives to call into their local branch of Marks and Spencer, or some other supermarket chain, to buy ready-made meals on their way home from work. It is even easier to buy a “take-away” from a local restaurant or pick up the phone and order a pizza to be delivered to your home. 操作提示、通过题干后的下拉框选择题目的正确答案。 1.The secret of fast food chains’ success is {}.

WEDNESDAY, JUNE 26, HORNS REV, DenmarkIn the lead up to the Earth Summit in Johannesburg in August, the Greenpeace ship, the Rainbow Warrior, today began the first part of a global journey to support the development of renewable energy around the world. Offshore wind in the North Sea alone can produce nearly twice the electricity needs of the North Sea countries. Using only 20% of that would supply one-third of these countries’ electricity. Greenpeace are going to challenge governments and industry to make this happen. The Rainbow Warrior sailed today to Horns Rev, the world’s largest offshore wind park, which is being built off the coast of Denmark. Another Greenpeace ship, the Arctic Sunrise, will begin the second part of the global tour in Southeast Asia next month. “During these weeks, Greenpeace will be conducting this global tour with two ships to show that renewable energy is ready and able to replace dirty coal, oil, gas and nuclear power – not only in the future, but today”, said a Greenpeace spokesperson. Wind energy is reported to be competitive with coal and gas power generation and clearly beats costly nuclear power. The UK government’s energy review claimed that wind energy will be the cheapest energy source by 2020. Next month, the Arctic Sunrise will be visiting the Philippines and Thailand, where communities are rejecting dirty, old-fashioned energy technology like coal-fired power stations and demanding clean, renewable energy. 1.The purpose of the global tour was{}.

WILL ENGLISH ALWAYS BE THE MAIN INTERNET LANGUAGE? The Internet’s ability to connect a wide range of cultures encourages variety. However, for the time being, English dominates online because from the start it was the lingua franca of cyberspace. Will this always be the case? Currently about 70% of Internet is in English, but only about 44% of Internet users are native English speakers. Worldwide, native Spanish speakers outnumber native speakers of English online, and the number of native Chinese speakers is greater than both those groups put together. Statistics show that the situation is changing. For instance, three years ago 75% of web pages were in English, but that number has dropped to 50% today. Furthermore, Internet use among non-native speakers of English is growing at a faster rate than that of native English speakers. By 2003, the number of native English-speaking web users will have dropped to 29%, according to one estimate. As a result, some researchers say that the early predominance of English is going to decline. They say that English will keep a special role in connecting communities whose native languages are different, but in about 20 years’ time, Spanish, French, Arabic and Chinese will also have taken on this connecting role. If this is true, then monolingual native English speakers may be more likely to learn another language and also become bilingual, or even multilingual. 1. English became the dominant Internet language because {}.

76、

Which of the following is NOT true according to the passage?{}

77、

The number of English web pages has{}in the recent 3 years.

78、

{}is NOT mentioned in the passage to have the possibility to take on the connecting role of English.

According to this passage, which of the following statements is true about the future of English?{}

80、

Two hundred years ago, it took several weeks for the news of the important Battle of Trafalgar to reach London. Nowadays, you can watch a terrorist attack as it happens anywhere in the world. The communications revolution means that we are constantly bombarded with instant news. This has great advantages, but it also raises important questions. Satellites have enabled immediate reporting worldwide. A reporter can send the news to a network like CBS News and within seconds it can be all over the world. They send electronic reports that go straight into the newspaper or onto the TV screen. Reporters can now also transmit images through their mobile phones. Consequently, live, “on-the-spot” reporting has become the norm and TV viewers can get a much better idea of what a natural disaster, a conflict or an interesting scientific discovery is like. In recent years, several changes have occurred in the ownership of news media. Networks owned by large companies and governments have become bigger and very powerful. These networks – such as BBC News 24 – are hungry for news and have huge audiences. However, there can only be a limited number of such networks and their ownership is a big issue. Some companies not only own TV and radio networks but newspaper groups as well. Who decides what news to publish and what sort of “spin” to put on it? Is it always objective? There are now “spin doctors” who manipulate the news, emphasising certain parts and not others – and as a result, much of it is not neutral. Therefore, the question of control of the media matters very much. In some cases, the media companies are more powerful than governments. They can even influence elections. So the question is – should they be controlled and if so, by whom?  操作提示、通过题干后的下拉框选择题目的正确答案。 1.Immediate reporting has become possible all over the world because of  {}.

{}has become the norm.
