1、New Product Will Save LivesDrinking water that looks clean may still contain bugs, which can cause illness. A small company called Genera Technologies has produced a testing method in three stages, which shows whether water is safe. The new test shows if water needs chemicals added to it, to destroy anything harmful. It was invented by scientist Dr. Adrian Patton, who started Genera five years ago. He and his employees have developed the test together with a British water company.Andy Headland, Genera\'s marketing director, recently presented the test at a conference in the USA and forecast good American sales for it. Genera has already sold 11 0fits tests at $42,500 a time in the UK and has a further four on order. It expects to sell another 25 tests before the end of March. The company says it is the only test in the UK to be approved by the government.Genera was formed five years ago and until October last year had only five employees; it now employs 14. Mr. Headland believes that the company should make around $19 million by the end of the year in the UK alone.The British government is helping Dr Parton to sell the tests abroad.【单选题】

B.Wrong

C.Not mentioned

正确答案:C

答案解析:本题的意思是：英国政府正帮助Parton销售这种产品。原文根本没有提到这一信息，故选C。

2、Woman workThough some people have suggested that women should return to housework in order to leave more jobs for men, the idea has been rejected by both women and men in public ____ polls.Lately some union officials have suggested that too many women are employed in types of work more suitable for men and that women should step aside to make way for unemployed young men. They argue that women, especially women in their childbearing years,actually delay economic development and result in productivity, poor quality and inefficiency.To solve the problem, they suggested that working women stay at home while their husbands or brothers were given double wages. They argue that under these circumstances, families would remain their same level of income, and women could run the house and raise children much better,The suggestion, however , has been flatly rejected by 9 0ut of 10 people polled .Some other people have suggested another way called "phased employment" theory. The theory suggests that a woman worker take leave from her job when she is seven months pregnant and stay off the job until her baby reaches the age of 3. It suggested that women on leave receive 75 percent of their normal salary and be allowed to return to work after the three-year period. This will benefit children, women, their families and the society and it definitely seems to be more acceptable than the suggestion that women return to their homes forever.【单选题】

A.attitude

B.reaction

C.idea

D.opinion

正确答案:D

答案解析:poll的本意是“民意测验”，它的修饰词只能是opinion，其他选项在此则读不通。

3、A Bad IdeaThink you can walk, drive, take phone calls, e - mail and listen to music at the same time? Well, New York\'s new law says you can\'t. And you\'ll be fined $ 100 if you do so on a New York city street. The law went into force last month, following research and a shocking number of accidents that involved. people using electronic gadgets (小巧机械) when crossing the street.Who\'s to blame? Scientists say that our multitasking (多任务处理) abilities are limited. "We are under the impression that our brain can do more than it often can," says Rene Marois, a neuroscientist (神经科学家) in Tennessee. "But a core limitation is the inability to concentrate on two things at once."The young people are often considered the great multitaskers. ____ A group of 18 to 21 years old and a group of 35 to 39 years old were given 90 seconds to translate images into numbers, using a simple code. The younger group did 10 percent better when not interrupted. But when both groups were interrupted by a phone call or an instant message, the older group matched the younger group in speed and accuracy.It is difficult to measure the productivity lost by multitaskers. Jonathan Spira, chief analyst at Basex, a business - research firm, estimates that the cost of interruptions to the American economy is nearly $650 billion a year, The estimate is based on surveys with office workers. The surveys conclude that 28 percent of the workers\' time was spent on interruptions and recovery time before they returned to their main tasks.【单选题】

A.Talking on a cell phone while driving brings you joy anyway.

B.The estimate is based on surveys with office workers.

C.The younger group did 10 percent better when not interrupted.

D.However, an Oxford University research suggests this perception is open to question.

E.Scientists say that our multitasking (多任务处理) abilities are limited.

F.And you\'ll be fined $ 100 if you do so on a New York city street.

正确答案:D

答案解析:本题有一定的难度。可用排除法和代入法。本题的上一句谈到了年轻人常被认为是能同时兼顾多个任务的，下一句又谈到了一项试验表明年轻人和年纪大的没有多少差别，所以可以推断此处应该表达转折的意义。回来看选项，把D代入文中，符合逻辑，答案是D。

4、U. S. to Start $3. 2 Billion Child Health Study in JanuaryA study that will cost $3. 2 billion and last more than two decades to track the health of100,000 U. S. children from before birth to age 21 will be launched in January, U. S. health officials said on Friday.Officials from the U. S. government\'s National Institutes of Health said they hope the study, to be conducted at 105 locations throughout the United States, can help identify early-life influences that affect later development, with the goal of learning new ways to treat or prevent illness.The study will examine hereditary and environmental factors such as exposure to certain chemicals that affect health.Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air, water, dust and materials used to construct their residences, the NIH said.Officials said more than $200 million has been spent already and the study is projected to cost$3. 2 billion."We anticipate that in the long term , what we learn from the study will result in a significant savings in the nation\'s health care costs," Dr. Duane Alexander, who heads the NIH\'s Eunice Kennedy Shriver National Institute of Child Health and Human Development, told reporters.The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up pregnant women whose babies will then be followed to age 21.Some of the early findings will be about factors behind pre-term birth, which has become more common in recent years, according to Dr. Peter Scheid of the NIH, who heads the study.The people taking part will be from rural, urban and suburban areas, from all income and educational levels and from all racial groups, the NIH said.The aim of the study is to find new ways to ____. 【单选题】

答案解析:短文的第2段提到了此项研究的goal，即aim，这便是“learning new ways to treat or prevent illness. ”

5、RobotsThe most sophisticated (先进的) Japanese robots, which have vision systems and work at very high speeds, are still based on American designs. Studies of robots, particularly computer control software, are considered to be generally less advanced in Japan than in America or Europe.Although industrial robots were originally developed as devices for simply handling objects, today their commonest uses are for more skilled work like welding (焊接), spray-painting and assembling components.In Britain robot sales appropriately peaked in 1984, but have been declining ever since. This is partly because British wage rates are too low to make robots financially attractive and partly because engineers now have more experience with robots and are more aware of the difficulties of introducing them effectively.It has been calculated that a robot uses on average about 100 times more energy than a human to do an equivalent job.It is estimated that 20% of all comic book heroes in Japan are robots. This is an enormous number because comics are so popular that they make up a third of all material published in Japan. The reliability of robots is measured in their MTBF or mean time between failures. This has risen from about 250 hours in the mid-1970s to about 10,000 hours today (equivalent to working 18 hours a day for two years). One way robot manufacturers have increased reliability is to test every single component they buy, instead of the normal procedure of just testing a small .sample.The biggest single benefit of introducing robots claimed by Japanese companies is that they increase quality control. One programmed robots can work more accurately and consistently than humans, who can get tired and bored.Robots are less popular in Britain today partly because________.【单选题】

A.too much energy

B.based on American designs

C.they are too costly

D.they are not reliable

E.quality control

F.free of charge

正确答案:C

答案解析:根据题干中的线索词in Britain可定位到第三段，该段共两句，第一句讲述了自1984年后英国的机器人销量就一直下降，第二句说明了其原因。原因之一便是英国人工资水平偏低，使机器人成为可望而不可即的高消费品。选项C与其意思相符，故C为正确答案。
