30. The Effect of Decoding the Human Body
The Human Genome Project will revolutionize the detection, prevention and treatment of conditions of certain diseases. Genes help early detection of diseases and fix health problems, not just to predict them. Genetic medicines will be aimed at the causes of disease rather than the symptoms and doctors will start prescribing different treatments for different patients, depending on their genetic profiles. Many potential diseases will be cured before they arise.
But decoding the book of life poses moral dilemmas. It threatens to undermine privacy and bring on genetic discrimination in marriage, insurance and employment. With knowledge of our genetic code, those who have got certain undesirable genes may be discriminated when choosing their spouses. If genetic tests predict mental dullness, short stature or other undesirable traits before babies are born, the society may look down upon children whose parents let them be born , the society may look down upon children whose parents let them be born with those traits. Employers may take your genetic profile before they offer you a job.
In my opinion, the completion of the Human Genome Project is a great breakthrough in human history. It will change the way we live and even the way we think about who we are to prevent genetic discrimination, in insurance and in employment based on genetic tests.

31. The Orientation of China's Cross-Century Economic Reform
The economic reform in the past 20 years has brought us tremendous changes in every way. China ranks No 9th according to its GNP in the world.
Nevertheless, we are still facing serious challenges. A too large population and lower educational level still prevent us from more successful development. So, we should ask ourselves what we should do to promote our reform more fruitfully.
To this problem, my answer is to strengthen the reform of our education and economic management to improve the qualities of our young people and our material products after joining WTO. At the same time we have to establish better laws of labor or distribution systems to arouse people's working enthusiasm.


32.The Information Age and the Best Way to Use Information
It is often said that ours is the information age.
'Computers are playing a more and more important role in modern society. They are already widely used in industry and in universities to do extremely comp1icated work in all branches of learning. They can solve the most complex mathematical problems or put thousands of unrelated facts in order. Because they work accurately and at high speeds, they save research workers years of hard work. They play a key role in automation. Besides, they have found applications in business, transportation, education and other fields. Computers have brought important social consequences.
Computers are also entering ordinary families. As computers are being made small, cheap , and at the same time easy to use, more people buy computers for their homes. We
use computers to control the work of washing machines, TV sets, electrical cookers and other electrical appliances. We use computers to process and store all kinds of information. We also use computers to entertain ourselves by playing games on them. There is no limit to the application of computers in our lives. Despite all the advantages t computers can never take the place of human brains. Although computers work much faster and much more accurately than human beings, they can not “think". They need detailed instructions from human beings in order to be ab1e to operate. They can never lead independent lives, or “rule the world” or "rule the would "by making decisions of their own. No matter how capable they are, they are our servants, not our masters.

33. Why Governmental Workers also Have to Go abroad?
More and more people want to go abroad for academic advancement or business exchanges. So do the government leaders and middle-level governmental workers to improve their public services.
Some people, however, keep an critical eye in this problem, saying this is "a kind of making a tour on public money". Others say it is a kind of extra pay for their over-service. I don't agree with them because they fail to see the importance to be open and progressive in running governmental affairs by exchanging and learning experience from the outside world. "Seeing is believing" can be very useful for the governmental workers to improve their own work. And in many cases, it can even bring about a major change in their working style.

34. The Problem in Using Water
Water is indispensable to life. It is used for drinking and washing every day. We also need water in great quantity in industry and agriculture. However, not everyone is aware of the importance of water. They tend to think since there is plenty of water, it does not matter if we waste a little of it. They don’t know or they don’t want to know that water shortage has become more and more and serious in many cities, even in Beijing. If blind consumption of water is allowed to continue, the problem will become worse and worse.
In order to cope with the shortage of water, the government has to take more effective measures. On the one hand, fines are to be imposed on those factories units that use water lavishly. On the other hand, the government should carry on intensive education among the people. For us ourselves, we should economize on water conscientiously.

35. Compare with the domestic hen and the duck
The domestic hen and the duck both belong to the bird category. They have some features in common such as wings, feet, beak, flight, nest, migration, food and eggs.
The domestic hen has short wings which it rarely uses because it has a heavy body and lives on the ground. It is clumsy in flight and can cover only short distances. Its feet are designed for scratching the ground to find seeds and worms. It will also eat almost any other kind of food. Hens nest on the ground. They have been bred for egg production and can lay up to 300 eggs a year.
A duck has webbed feet so that it can swim easily and walk on soft ground. It has a long, flat beak which it uses to search for food in river and pond mud. It has powerful wings which enable it to fly long distances. It nests in grass at water’s edge. Ducks migrate long distances. A duck lays 5 to 12 eggs at a time and may lay twice a year.
In conclusion, although there are something different among these two birds, the basic features are quite similar.
