　　The Role of Migrant Workers

　　Migrant workers have made a great contribution to the prosperity of cities. They leave their home-land for better chances. Some want to change their destiny, some want to make a fortune. Whatever the purposes they cherished when millions of them streamed into big cities, they have promoted the development of cities.

　　Most of the migrant workers are hard working and unafraid of hardships. They take up the dirtiest, the most strenuous or dangerous jobs which city laborers are unwilling to do. With lots of building they have set up and streets they have kept clean, they have helped modernize and beautify cities. Not only have they become the main work force in the construction sector, they also have helped liberate city women from heavy housework chores by taking care of the babies, cleaning houses or providing any other services citizens need.

　　Although some of the citizens complain about the increasing number of the problems such as theft, robbery a few of migrant workers have committed, most of the citizens agree that their contribution is obvious, and with better management, their role in the construction of cities will definitely be greater.

　　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.

　　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.

　　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. Weuse 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.
