(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.

(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.

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)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

(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.
