单选题Directions: Read the following passages and choose the best answers to the questions. Third World Countries often mistakenly decide to permit rapid industrialization. When this industrialization occurs, many new factories open, and workers get jobs. Unfortunately, many of these new jobs are not permanent. The leaders of an industry want their factories to be as productive as possible, and they will do anything to achieve that goal. Whenever they can, they take advantage of automation, which means that workers are replaced by a more efficient machine. As a result, a worker trained for a specific factory job becomes unemployed, and the profits of the factory owners are maximized. Many experts in Third World Economics are concerned about rapid industrialization because it brings problems as well as progress. Citizens of these countries need jobs that will last, not jobs that are temporary. In the opinion of these economists, the leaders of Third World Countries should be aware of the dangers as well as the advantages of rapid industrialization.

单选题 Man finds living together with his own species (物种) difficult enough and living together with other species almost impossible. Our usual solution is to kill off anything that get in our way. Even on those rare occasions when we do enter a relationship with other species, it is heavily biased (带有倾向) in our favor. The other species benefit only when they suit our own interests. Our attempts to communicate with another species are concerned mainly with giving orders in our own language and having them obeyed. Probably our best attempt has been the whistle language that is used in the shepherd-sheepdog relationship. This is a system that is natural to neither species, but one that both can under stand. Its only fault lies in fact that the bias is still there—the dog cannot whistle for the man. But now comes news of a piece of research that promises for the first time, to open up two-way communication between man and another species. At the University of Nevada in the western United States, animated (活跃的) conversations are being held with a young female chimpanzee (黑猩猩) called Washoe. Allen and Beatrice Gardener have succeeded in doing this because they have used an entirely new approach, an approach based on the natural abilities of the champanzee. Past attempts to communicate with chimpanzees have failed because the researchers tried to make their animals use a local language.
