4、 should spend about 40 minutes on this task.（分数：2.00）_解析：2.Should animals be used in testing new drugs and procedures?（分数：2.00）_正确答案：(正确答案： Every year, millions of animals undergo painful suffering or death in the name of scientific research into the effects of drugs, food additives, cosmetics and o
5、ther chemical products. While most people think animal testing is necessary, others are upset by what they see as needless suffering. This essay looks at some of the positive and negative aspects of animal testing. Many medical treatment and procedures have been developed from experiments on animals
6、. Since animals share many features with humans, scientists use animals to test the safety and effectiveness of newly developed drugs before pilot testing on small groups of patients. Medical teams practice new operating techniques such as transplants on animals. Without animal testing, many procedu
7、res or new drugs would be extremely unsafe. However, many people are concerned that animals are suffering unnecessarily They do not believe that every new drug needs to be tested on animals, especially with the huge database of knowledge we have, and modern computer models. They are also worried tha
8、t many animal tests are ineffective, pointing out that many drugs have had to be withdrawn from the market despite extensive testing. They particularly feel that animal testing should not be used for non-essential products such as cosmetics, cleaning products etc. Furthermore, some campaigners would
9、 like to see certain tests replaced and more humane methods used. We need to make sure that the millions of animals that are used for testing new products are guaranteed a minimum of suffering Although some animal testing may be unavoidable at present, treating our fellow creatures as mercifully as
10、possible will demonstrate our humanity.)解析：3.The importance of biodiversity is being increasingly recognised as more species come under threat. What can be done to maintain biodiversity?（分数：2.00）_正确答案：(正确答案： As natural resources come under increasing pressure, the list of endangered plants and anima
11、ls continues to grow. The causes are many: developments in agriculture, mining, forestry and transport. Some would argue that the loss of biodiversity is a price we must pay for progress. In my view, however, there is much that governments can and should do to protect the worlds plants and animals.
12、Governments could promote greater understanding of plants and animals by investing in the research and preservation efforts of universities, zoos and botanical institutes. This may ensure the survival of individual species and produce tangible benefits in the form of new medicines and products. Howe
13、ver, this strategy alone would do little to protect whole ecosystems that are under threat. An alternative strategy would be to protect natural habitats by expanding nature reserves. This would have immediate positive consequences for those areas by preserving delicate ecosystems. However, this stra
14、tegy also has limitations. It does not protect from phenomena such as acid rain and water pollution, which can cross boundaries and affect large areas. The most effective solution is to limit the damage at source. Companies that engage in practices that harm the environment should be required to dem
15、onstrate that they have taken all reasonable efforts to minimise the damage. Public contracts for roads and buildings should only be awarded to firms that haVe a good environmental track record. The strategies outlined above: preservation, protection and, above all prevention, can do much to reverse
16、 the destruction that threatens the worlds plants and animals. The aesthetic and practical benefits of doing so are well worth the cost.)解析：4.Fossil fuels (e.g. coal, oil, natural gas) are the main sources of energy in many countries, but in some countries the use of alternative sources of energy is
17、 encouraged. Is it a positive or negative development?（分数：2.00）_正确答案：(正确答案： I think that the focus on alternative, renewable sources of energy in some countries is an excellent idea and that countries that concentrate on fossil fuels seriously need to consider what they are doing. In this essay I sh
18、all explain why. One simple point is that fossil fuels are bad for our environment. The use of fossil fuels leaves behind particles in the air which can cause breathing disorders and pollute the natural world. The environment is naturally able to deal with a certain amount of pollution, but humans a
19、re now so numerous and our use of fossil fuels is so vast that this has now become impossible. As a result, we are faced with choosing renewable forms of energy or destroying our natural environment. Another point is that fossil fuels will eventually run out. This is a simple matter of logic. It tak
20、es millions of years for fossil fuels to form, yet it takes us far less time to use them. The problem is that nobody is sure about exactly when fossil fuels will run out. This is largely due to the fact that we dont know where it all is. Some people claim that we can start using alternative energy s
21、ources when the fossil fuels run out, but this is not a real option. When fossil fuels really start running out, there will almost certainly be wars over the remaining supply and, perhaps more importantly, we will need a good supply of fossil fuels to create the energy required to construct wind tur
22、bines, solar panels and other equipment that alternative energy requires. To conclude, it seems obvious to me that we need to start developing alternative energy oh a large scale now, rather than waiting.)解析：5.Differences between countries are becoming less evident nowadays. People tend to have the
23、same films, music, brands, TV channels, etc. To what extent do you think the disadvantages outweigh the advantages?（分数：2.00）_正确答案：(正确答案： As a result of the accelerating process of globalisation in various aspects, young people in different countries are more likely to enjoy the same music, films or
24、television programmes, which inevitably result in some similarities between different countries. Some people may claim that it is more a curse than a blessing for the world. One argument commonly raised is that this process will be damaging to the globes diversity. When locals are bombarded with for
25、eign products or culture, they may gradually abandon their traditional values or ways of life, so this would have a negative impact on their national or cultural identities in the long run. They even quote numerous examples such as the Eskimo in Iceland and the Mosuo ethnic group in Southwest China
26、to illustrate their points of view. While this is particularly true of some minority cultures, I want to point out that they are still special cases instead of the general rule. Generally speaking, sharing something across the globe can contribute to a deeper mutual understanding between different n
27、ations. For example, a piece of country music by John Denver may well shed light on the peaceful daily life of Americans while a pop song by Cui Jian (one of the first great pop musicians in China) may introduce to Westerners a much more familiar China. What is more, an experience of some alien cult
28、ures may encourage more appreciation of the local ones, rather than assimilation or malfunction. There is overwhelming evidence on this when we consider Japan, or China, or even the US, which tend to incorporate the international elements into the local. To conclude, I am quite optimistic about the prospect of an increasingly similar world. Of course, some minority groups may be put at a disadvantage for they cannot receive equal attention as the superpowers. So I also advocate that governments or other bodies should make efforts to bring these minorities into the international horizon.)解析：
