C.1. The answer is yes. But the question is open to discussion. Impulse can not stay long without careful thinking. Writing is also an art and art is cultivated

3. In most cases a good story is rewritten. But there are writers who think very carefully about the story to be written before they start writing. Careful thinking and rewriting are of the same nature here.

C. 1.The author's hypothesis is based on the following facts: the growth rate of the world

population is now only one percent a year; 44 percent of the world's people live in countries where fertility has already fallen below the replacement rate, and fertility is falling almost everywhere else. The reason is that population changes depend on the values people hold. As long as the modern value of saving efforts and money by raising fewer children remains widespread, the world population will not stop declining.

(Of these views, you may have your own judgment, discuss with your partners.)

2.The author suggests that human values is one of the determining factors of population fluctuation. Modern way of life has led to the declination in population in the modernized counties, and whether the world population will grow or dwindle depends on the values people hold in the future. You may agree, partly agree or disagree to the author's view. Still you may also put forward new views regarding the relation between human values and population.

C．1. Genetically modified food is made from crops and vegetables genetically changed by scientists. GM food has aroused great dissentions among governments, scientists, farmers, and consumers. On one hand are the high quality crops due to the gene technique, on the other hand are the potential risks.（While giving your ideas, consider the interests of different peoples.）

3. From the text we can see that the food fight between the U.S. and the E. U. comes as much

from the concern for their own interests as from safety considerations. While the E. U. banned the non-proved GM food from the U.S., France is still churning out GM crops. Anyway, it shows that people are more alert to the potential dangers of the GM food. （Your comments can be positive or negative. Consider that while the consumers' attitudes determine the popularity of the GM food, the government, scientific research, media propaganda and other factors can influence the consumers' decisions.）

C. 1. It doesn't take a genius to work out why advertisers try hard to market directly to children.

British children aged four to fourteen spend an average of ￡2.49 each week. This makes the pocket money market worth more than ￡1.5 billion a year, according to a recent report from management consultancy Datamonitor. In the US the pocket money market is worth a massive $64 billion a year. Selling to children has become big business.

2.Many measures have been taken to achieve this purpose. For example, Winthrop Publications in London has just launched the International Journal of Advertising and Marketing to Children. One article reports that 60 per cent of children aged two to eleven know by the end of October what they want for Christmas, and that for girls under seven the biggest deciding factor is what they see on television.
