【正文】 m Beijing University to MIT, universities congregate a lot of preeminent scholars and professors whose main jobs are the academic research. They are responsible to impart the academic knowledge to the young generation. In summary, from what has been discussed above, we may safely arrive at the conclusion that the theoretical courses are not as obsolete, profitless and unimportant as some people believed. And our universities should be responsible to provide the theoretical knowledge 15. What Should Governments Do to Help Prevent Global Warming? 政府如何防止全球變暖 The earth’s temperature is rapidly changing. As a result there has been a lot of climate change such as heat waves, droughts and floods. Scientists believe that this is the result of human activity, which is polluting the Earth’s atmosphere. This could bee a disaster if governments do not act to help prevent global warming. They can act in three ways。s population will approach its peak by the middle of the next century, with the percentage of the people aged beyond 60 making up percent of the total. That means one out of every four people will be elderly. As for the issue of aging, its situation has been growing increasingly severe in spite of the fact most people are still ignorant of the problems it brings about. Firstly, with families being smaller and living pace escalating, it is even graver for families to care for aged members adequately. Secondly, aging causes a relative decline in working force in that fewer people have to support the increasing aged people. Consequently, the productivity of the whole society is affected to some extent. Thirdly and most importantly, the aging of population in China resulted from the successful implementation of family planning has not been synchronized with national economic progress. The rapidity of the population39。s aging has made it more urgent for the adoption of countermeasures. No doubt they key is to build a solid economic foundation. Meanwhile, importance shall be attached to overall social progress by changing the backward situation in social security, welfare and service. What39。 by supporting research, by making laws and by keeping the general public informed. Firstly, governments can support research. For example, they should encourage panies to develop vehicles that cause less pollution. They should also support alternative sources of electricity from wind and water rather than from oil and coal. As well, they should sponsor conferences to discuss the effects of greenhouse gas emissions and possible solutions to the problem. Secondly, they should make laws that limit the amount of greenhouse gases that panies can emit. Private panies should be rewarded for following these laws. They should also be punished for 6 creating pollution. Finally, everybody is affected by global warming. Therefore, it is important that governments involve individuals in the problem solving process. For example they should encourage households to save as much energy as possible by using more efficient light bulbs or less hot water. They should also encourage the public to recycle, and this should be pulsory for everyone. Another way of saving energy is by public transport systems. Governments should spend money on public transport to make it as easy as possible for the public to save energy. In summary, it is clear that there are a lot of things that governments can do to prevent global warming. They should involve panies, support scientists and encourage individuals to protect the pla. 16. Advantages and disadvantages of private cars. 私家車的優(yōu)缺點(diǎn) With the fantastic spur both in industry and in economy in China, the number of people who own private cars is on the rise. Some people have bought cars of their own, and others are planning to buy cars. But there have been two quite different views on this phenomenon. Some claim that there are many advantages brought about by cars. First, the automobile industry provides jobs for countless workers and strong support for other industries. Second, if conditions permit, owning a car can make us work more efficiently. Finally, life will bee more convenient. A car allows one to move freely and with a car there is no need to wait for the bus in the cold or under the burning sun. However, others strongly object to the increase in developing private cars. They hold that automobiles will give rise to a series of problems. In the first place, as more and more cars are produced and run in the street, a large volume of poisonous gas will be given off, polluting the atmosphere and causing actual harm to the health of people. Next, private cars contribute to traffic congestion so greatly that the advantages gained in fort and freedom is often cancelled out by the frustration caused by traffic jams. The last problem is the increasing number of car accidents that have killed and will kill a lot of people in a friction of a second. In my opinion, although automobiles have been playing a vital part in the daily activities of our society, they also bring us numerous troubles such as more serious environmental pollution, more traffic accidents and more energy consumption. They drink up huge amounts of fuel and throw out huge amounts of pollutants. Traffic accidents kill thousands and thousands of people each year and cripple more. Jams waste our precious time. Therefore I am against developing private cars. 17. Nowadays we are producing more and more rubbish. Why do you think this is happening? What can governments do to help reduce the amount of rubbish produced? I think it is true that in almost every country today each household and family produces a large amount of waste every week. Most of this rubbish es from the packaging from the things we buy, such as processed food. But even if we buy fresh food without packagin
