(3)Like TV, computers benefit people hugely. (4)With the computer, the home will become a library, a school, an office and an entertainment center. (5)All transactions, from banking to shopping, will be performed electronically and all information, from train schedules to discount-price goods, will be as close as the press of a key. (6)In addition to providing us many of the facilities and services we now must  , with the Internet, the computer will even let us communicate directly with other homes and with information sources worldwide. (7)Despite the increase in efficiency and convenience generated by the computer, the changes it brings could very well lead to potentially adverse consequences. (8)For example, as nearly all activities could be conducted in the comfort of our homes, we could all become hermit-like, never feeling any need to leave the house. (9)This would be unfortunate because our children especially will become so addicted to computers that they might never be exposed to social interaction.

(3)Some think of them as a sign of economic progress and a miracle of modern architecture.

(5)Yet others, speak of the problems skyscrapers have brought. (6)They complain that the monstrous edifices interfere with television reception, blot out the sun and create many dark sunless streets. (7)Besides, excessively large masses of human beings working in a single gigantic building overburden public transportation. (8)Lighting, heating, and air conditioning strain energy supplies, to the extent that skyscrapers become lavish consumers, and wasters, of electric power.

Should Euthanasia Be Legalized?

1． 有的人贊成安樂死
2． 有的人安樂死的合法化
3． 我的看法

(1)Euthanasia, a quiet and easy death, or “mercy killing” as we call it recently has made the headlines frequently. (2)Many people applaud it and argue that euthanasia should be legalized.
(3)As is pointed out, to practice euthanasia can benefit both the patient and his family. (4)To a terminally ill person who is suffering excruciating pains day and night or living “ like a vegetable”, to be allowed to end his life painlessly is a good release. (5)To his family it is also a big relief considering the financial and emotional drain on them that having to sustain his life entails. (6)However, the legalization of euthanasia may also bring with it problems our society has not previously faced. (7)Is it humane, for example, that a terminally ill patient is thus caused to feel guilty for remaining alive because he does not want to die? (8)Is it wise that a patient is killed alive simply because of a mistaken terminal diagnosis? (9)And is it possible that euthanasia could be taken advantage of for some ulterior or even criminal purposes?
(10)Since the legalization of euthanasia will raise serious moral and social issues, the decision our society makes about euthanasia will undoubtedly have tremendous consequences in society.

The Development of a Private Car

1． 小汽車開始進(jìn)入中國的普通家庭
2． 小汽車帶來的方便和舒適
3． 小汽車帶來的交通和污染問題

(1)With the increase in the general standard of living, some ordinary Chinese families begin to afford car. (2)Yet opinions of the development of a private car vary from person to person.
(3)Some claim that there are many advantages in possessing a car. (4)It gives a much greater degree of comfort and mobility. (5)The owner of a car is no longer forced to rely on public transport, and hence no irritation caused by waiting for buses or taxies. (6)With a car he can go where he likes and when he wants, so much so that he can enjoy his leisure to the full by making trips to the country or seaside on the weekends, instead of being confined to his immediate neighbourhood. (7)However, others strongly object to developing private cars. (8)They maintain that 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. (9)In fact, private cars contribute to traffic congestion so greatly that the advantages gained in comfort and freedom are often cancelled out by the frustration caused by traffic jams
(10)Whether private cars should be developed in China is a difficult question to answer, yet the desire for the comfort and independence a private car can bring won’t be eliminated.

Rural Workers: A Mixed Blessing for the City

1． 20世紀(jì)90年代以來，大批民工流入沿海大城市

(6)They have become an indispensable part of urban life to a point where the machinery of a city connot operate without those cogs, though small and unnoticed. (7)Yet an anti-migrant attitude runs consistently through the mainstream of urban consciousness. (8)City residents complain that migrant workers have worsened traffic and sanitation problems and have threatened to take already scarce urban jobs. (9)They also blame them for the sharp rise in the urban crime rate.
(10)Despite the problems posed by migrants, one thing is certain: a grand, prosperous edifice of the city is based on the work of millions of migrant workers.
