2009年职称英语考试理工类(C级)试题及答案
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.
23. Paragraph 2 _____________
24. Paragraph 3 _____________
25. Paragraph 5 _____________
26. Paragraph 6 _____________
27. Even the most sophisticated Japanese robots are __________.
28. Robots are less popular in Britain today partly because ________.
29. One disadvantage of using robots is that they consume ___________.
30. The use of robots increases ___________.
A too much energyB based on American designsC they are too costlyD they are not reliableE quality controlF free of charge

第一篇 Eta Carinae
As possibly the galaxy’s (银河) most massive star, Eta Carinae is now engaging in some very unusual behaviour. Australian astronomers, being in the Southern Hemisphere (半球), are able to observe it clearly.
In the 19th century, Eta Carinae was for a time the third brightest star in the sky. It has now become less bright so that binoculars (双筒望远镜 )are needed to see it. “It seems to be brightening and becoming less bright over a period of many years”, said Dr Bob Duncan from the Australia Telescope National Facility.
While it is not unusual for stars to vary in brightness, the period is usually much shorter. “Since 1992 it has become four times brighter, and then last year it began to drop dramatically,” he said.
The problem in observing Eta Carinae is that it has been surrounded by a cloud of gas and dust, making it hard to see the star directly. However, radio waves and infrared light (红外线)can pass through this cloud, so telescopes that receive these wavelengths can observe what is occurring.
Eta Carinae is of particular interest to astronomers because it seems to be in its death throes(剧痛). Being so large it will end up as a supernova (超新星). There has not been a supernova in our galaxy since the invention of the telescope. While a 1987 explosion in a nearby galaxy gave astronomers plenty of valuable data, they are hungry for an even closer look.
