第9题
听力原文: We are now living in a world in which robots are taking over much of the work.Robots make our cars, fly our planes and work out wages.
But these robots are not mechanical men and women.They do not look like us.They are machines specially built to do some of the things that human beings can.
Although they may not look like us,robots need some human features in order to be able to do human work.First of all they need some kind of brain.Their "brain" is a computer,which has a memory to human member instructions and ability to control other equipment.Another essential feature of many robots is an arm that can do the kind of things that human beings can with their arms.One-armed robots are now coming into widespread use in industry.They are being used,for example,on car assembly lines.
The great advantage of robots over human workers is that they can work non-stop for long periods. They never get tired,and always work with the same accuracy.They can also work in conditions that humans could not bear.Last but not least,as more robots are built,their cost will come down.
Although robots are rapidly taking over many jobs in industry, they seem a long way from taking over in the home. The problem is that it would take a very complex and costly robot to perform. half the tasks involved in housework.
According to the speaker,what can the present-day robots do?
A.Drive cars.
B.Fly planes.
C.Pay wages.
D.Repair machines.

回答题。
Robots
1. The 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.
2. 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.
3. 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.
4. It has been calculated that a robot uses on average about 100 times more energy than a human to do an equivalent job.
5. 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.
6. The reliability of robots is measured in their M.T.B.F. 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.
7. The biggest single benefit of introducing robots claimed by Japanese companies is that they increase quality control. Once programmed, the robots can work more accurately and consistently than humans, who can get tired and bored.
