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.D.abcd bddb aaFast readingUnit 2ExerciseA. aB. bbc bdb abac C. 1. The authors 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 worlds 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 authors view. Still you may also put forward new views regarding the relation between human values and population.D.baa aba cdcFast readingPassage one 1-5 acdabPassage two6-10 caddbpassage three1-15 dccdbUnit 3ExerciseA aB bab cdb abb 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.）D aad bac cad bcc adFast readingPassage one 1-5 cbbab Passage two 6-10 badbbPassage three11-15 bbdad Unit 5ExerciseA. aB. bcadb caC. 1. It doesnt 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. Conferences and consultancies abound. Pay2000 and you can attend Kid Power 99 at any one of a string of European venues. The meetings offer workshops on what works with kids and why, peer group1 marketing and how to think like a kid. Consultancy firms will tell you how to build a wall of communication to influence your core consumer lifestyle from the moment said consumer is two years old. 3. From psychologists experiments about childrens response to ads, we can learn that children are not as gullible as they are thought to be. They become more cynical and sophisticated. Children are brand literate and they can see through marketing hyperbole. Either children are getting wise to the advertising game, and at an earlier age than in the 1970s and 1980s, or in the past psychologists underestimated their young subjects ability to work out other peoples motivation. From article reports we know that 60 per cent of children aged two to eleven know by the end of October know what they want for Christmas, and that for girls under seven the biggest deciding factor is what they see on television. Children are notoriously fickle, and advertisers have a hard job keeping up with their capricious tastes. Children are aware of the purpose of ads, those aimed children are no more sinister than those aimed at adults.
