2、 corresponding letter on the Answer Sheet with a single line through the centre. Questions 21 to 25 are based on the following passage: We can make mistakes at any age.

3、n I got that great job, did Jim really feel good about it, as a friend? Or did he envy my luck?” “And Paul why didnt I pick up that he was friendly just because I had a car?” When we look back, doubts like these can make us feel bad. But when we look back, its too late. Why do we go wrong about our

4、friends or our enemies? Sometimes what people say hides their real meaning. And if we dont really listen, we miss the feeling behind the words. Suppose someone tells you, “Youre a lucky dog.” Is he really on your side? If he says, “Youre a lucky guy” or “Youre a lucky gal,” thats being friendly. But

5、 “lucky dog”? Theres a bit of envy in those words. Maybe he doesnt see it himself. But bringing in the “ dog” bit puts you down a little. What he may be saying is that he doesnt think you deserve your luck. “Just think of all the things you have to be thankful for” is another noise that says one thi

6、ng and means another. It could mean that the speaker is trying to get you to see your problem as part of your life as a whole. But is he? Wrapped up in this phrase is the thought that your problem isnt important. Its telling you to think of all the starving people in the world when you havent got a

7、date for Saturday night. How can you tell the real meaning behind someones words? One way is to take a good look at the person talking. Do his words fit the way he looks?

There are several different stages of sleep, and they

13、too occur in cycles. If you are an average sleeper, your sleep cycle is as follows. When you first drift off into slumber (安睡), y our eyes will roll about a bit, your temperature will drop slightly, your muscles will relax, and your breathing were slow and become quite regular. Your brain waves slow

14、 down a bit too, with the alpha rhythm of rather fast waves predominating for the first few minutes. This is called stage 1 sleep. For the next half hour or so, as you relax more and more, you will drift down through stage 2 and stage 3 sleep. The lower your stage of sleep, the slower your brain wav

15、es will be. Then about 40 to 60 minutes after you lose consciousness you will have reached the deepest sleep of all. Your brain waves will show the large slow waves that are known as the delta rhythm. This is stage 4 sleep. You do not remain at this deep fourth stage all night long, but instead abou

16、t 80 minutes after you fall into slumber, your brain activity level will increase again slightly. The delta rhythm will disappear, to be replaced by the activity pattern of brain waves. Your eyes will begin to dart around under your closed eyelids (眼皮) as if you were looking at something occurring i

17、n front of you. This period of rapid eye movement lasts for some 8 to 15 minutes and is called REM sleep. It is during REM sleep period, your body will soon relax again, your breathing will grow slow and regular once more, and you will slip gently back from stage 1 to stage 4 sleep only to rise once

In chess a player tries to trap h

21、is opponents king in a series of moves. In creating a lens a lens designer attempts to “trap” light by forcing all the rays arising from a single point in the subject to focus on a single point in the image, as a consequence of their passing through a series of transparent( 透明的) elements with precis

22、ely curved surfaces. Since in both cases the ultimate goal and the means by which it can be attained are known, one is tempted to think there will be a single best decision at any point along the way. The number of possible consequences flowing from any one decision is so large, however, as to bevir

23、tually, if not actually, infinite. Therefore in lens design, as inchess, perfect solutions to a problem are beyond reach. Although this article will be concerned only with the design of photographic lenses, the same principles apply to all lenses. The lens designer has one enormous advantage over th

24、e chess player: the designer is free to call on any available source of help to guide him through the staggering number of possibilities. Most of that help once came from mathematics and physics, but recently computer technology, information theory,chemistry, industrial engineering and psychophysics

25、 have all contributed to making the lens designers job immeasurably more productive. Some of the lens es on the market today were inconceivable a decade ago. Others whose design is as much as a century old can now be massproduced at low cost. With the development of automatic production methods, len

26、ses are made by the millions, both out of glass and out of plastics. Todays lenses are better than the best lenses used by the great photographers of the past.Moreover, their price may lower, in spite of the fact that 19thcentury craftsmen worked for only a few dollars a week and todays lenses are m

27、ore complex. The lens designer cannot fail to be grateful for the science and technology that have made his work easier and his creations more widely available, but he is also humbled: it is no longer practical for a fine photographic lens to be designed from beginning to end by a single human mind.

These chapters are followed by one on Mechanics, covering matters of form that are peculiar to technical writing or else crop up in it with abnormal fr
