Passage 2 Questions 6 to 10 are based on the following passage:(77) Much unfriendly feeling towards computers has been based on the fear of widespread unemployment resulting from their introduction. Computers are often used as part of automated (自动化) production systems requiring a least possible number of operators, causing the loss of many jobs. This has happened, for example, in many steelworks.On the other hand, computers do create jobs. They are more skilled and better paid, though fewer in number than those they replace. Many activities could not continue in their present form without computers, no matter how many people are employed. Examples are the check clearing (交换) system of major banks and the weather forecasting system.When a firm introduces computers, a few people are usually employed in key posts (such as jobs of operations managers) while other staff are re-trained as operators, programmers, and data preparation staff. (78) After the new system has settled down, people in non-computer jobs are not always replaced when they leave, resulting in a decrease in the number of employees. This decrease is sometimes balanced by a substantial increase in the activity of the firm, resulting from the introduction of computers.The attitudes of workers towards computers vary. There is fear of widespread unemployment and of the takeover of many jobs by computer-trained workers, making promotion for older workers not skilled in computers more difficult.On the other hand, many workers regard the trend toward wider use of computers inevitable. They realize that computers bring about greater efficiency and productivity, which will improve the condition of the whole economy, and lead to the creation of more jobs. This view was supported by the former British Prime Minister, James Callaghan in 1979, when he made the point that new technologies hold the key to increased productivity, which will benefit the economy in the long run. According to Paragraph 2, without computers（）

Passage 1 Questions 1 to 5 are based on the following passage:I hear many parents complain that their teenage children are rebelling. I wish it were so. At your age you ought to be growing away from your parents. You should be learning to stand on your own feet. But take a good look at the present rebellion. It seems that teenagers are all taking the same way of showing that they disagree with their parents. Instead of striking out boldly on their own, most of them are holding one another’s hands for reassurance (放心).They claim they want to dress as they please. But they all wear the same clothes. They set off in new directions in music. But they all end up listening to the same record. Their reason for thinking or acting in such a way is that the crowd is doing it. They have come out of their cocoon (茧) into a larger cocoon.(76) It has become harder and harder for a teenager to stand up against the popularity wave and to go his or her own way. Industry has firmly carved out a market for teenagers. These days every teenager can learn from the advertisements what a teenager should have and be. This is a great barrier for the teenager who wants to find his or her own path.But the barrier is worth climbing over. The path is worth following. You may want to listen to classical music instead of going to a party. You may want to collect rocks when everyone else is collecting records. You may have some thoughts that you don’t care to share at once with your classmates. Well, go to it. Find yourself. Be yourself. Popularity will come—with the people who respect you for who you are. That’s the only kind of popularity that really counts. The author’s purpose in writing this passage is to tell（）
第三篇" Salty" Rice Plant Boosts Harvests British scientists are breeding a new generation of rice plants that will be able to grow in soil containing salt water. Their work may enable abandoned farms to become productive once more. Tim Flowers and Tony Yeo, from Sussex University’s School of Biological Sciences, have spent several years researching how crops, such as rice, could be made to grow in water that has become salty. The pair have recently begun a three-year programme, funded by the Biotechnology and Biological Sciences Research Council, to establish which genes enable some plants to survive salty conditions. The aim is to breed this capability into crops, starting with rice. It is estimated that each year more than 10m hectares(公顷) of agricultural land are lost because salt gets into the soil and stunts(妨碍生长)plants. The problem is caused by several factors. In the tropics, mangroves(红树林) that create swamps（沼泽） and traditionally formed barriers to sea water have been cut down. In the Mediterranean, a series of droughts have caused the water table to drop, allowing sea water to seep(渗透)in. in Latin America, irrigation often causes problems when water is evaporated(蒸发) by the heat, leaving salt deposits behind. Excess salt then enters the plants and prevents them functioning normally. Heavy concentrations of minerals in the plants stop them drawing up the water they need to survive. To overcome these problems, Flowers and Yeo decided to breed rice plants that take in very little slat and store what they do absorb in cells that do not affect the plants’ growth. They have started to breed these characteristics into a new rice crop, but it will take about eight harvests before the resulting seeds are ready to be considered for commercial use. Once the characteristics for surviving salty soil are known, Flowers and Yeo will try to breed the appropriate genes into all manners of crops and plants. Land that has been abandoned to nature will then be able to bloom again, providing much needed food in the poorer countries of the world. The word "affect" in Paragraph 6 could be best replaced by（）
