听力原文：M: Hi, mum!
W: Ah, there you are, I was getting worried about you. It's late.
M: Yes. I bumped into Lyn and went to the pub for a drink. She was telling me about a funny thing that had happened to her yesterday.
W: Oh, what was that？
M: Well, she was driving home from work when suddenly she saw an old lady on her hands and knees in the middle of the road.
W: Oh, her hands and knees in the middle of the road？
M: Yes, in front of her car. She was so shocked that she stopped without warning, and the car behind crashed into hers.
W: Oh! Was she hurt？
M: No, she wasn't, fortunately.
W: And what was the old lady doing on her hands and knees？
M: I'm just coming to that -- so Lyn got out of her car. Then the old lady picked up something, and walked away without saying a word.
W: Well. I never! She was lucky, Lyn didn't run her over.
M: Well, yes. Then a policeman came but he didn't believe the story.
W: Oh？
M: Luckily there was a witness, a man waiting for the bus. He saw it all. Guess what the old lady was doing？
W: I haven't the faintest idea.
M: She was looking for a false tooth.
W: A false tooth？
M: Yes, it fell out as she was crossing the road. The witness heard her mumbling, "Oh, my gold tooth."
W: I don't believe it.
M: It's true. Ask Lyn.
Why was the old lady on her hands and knees in the middle of the road？

听力原文：M: Doctor, I just don't know what's wrong with me. I always feel tired and rundown. My wife finally persuaded me to visit you to find out what the trouble is.
W: Looking at your case history I see that you had pneumonia four years ago and that you also had a minor operation last year. Did you have any long after effects？
M: Well. I don't remember so...
W: For instance, how long did you stay at home each time？
M: Just a couple of days. But about six months ago I was at home for about two weeks with a cold or something.
W: Did you see a doctor at that time or did you just stay at home？
M: No, I didn't see a doctor. The symptoms were about the same as this time. When I began to feel better, I returned to work.
W: And when did you start feeling so tired again？
M: It must have been about ten days ago. When I came home from work one night there just didn't seem to be any reason to go back the next day.
W: Well, it sounds as if your problem may be the kind of work you do. The tests I just made really don't show anything wrong. But I would like to make some further tests in the hospital.
M: That's fine with me.
W: All right, you can check in tonight, and I'll make the test tomorrow morning.

Although 【21】______ circuits made computers smaller, the processing units still consisted 【22】______ a number of circuits on separate chips. In 1971, an engineer working for Intel realized that a 【23】______ of circuits commissioned for an electronic calculator could all be put 【24】______ one chip, and that the resulting device could be used 【25】______ a general-purpose "computer on a chip". The result was the Intel 4004 -- the world's first microprocessor. Physically, it consisted of a silicon chip in a protective ceramic capsule, with a set of metal pins sticking 【26】______ that connected it to other components in whatever 【27】______ it controlled. It 【28】______ 2,300 transistors, 【29】______ 60,000 operations per second, and could be used for any device -- including computers and robots -- that required a "brain" for accepting 【30】______ and following a program of 【31】______ to produce an output. Within five years, many very powerful microprocessors had 【32】______ .The invention of microprocessors 【33】______ the stage for the arrival of the microcomputer, or personal computer (PC)-- an affordable machine for 【34】______ The first PCs, in kit form, appeared in the mid 1970s, and by the mid-1980s machines such as the Apple Macintosh and those based 【35】______ a PC first 【36】______ by IBM in 1981 were popular throughout the world. The success of these machines led to an explosion of software, in 【37】______ a range of spreadsheet, word-processing, graphic, educational, and games programs. Since the 1980s, a number of strong-intertwined themes have 【38】______ the computer revolution forward, including a continuing increase in the processing power and decrease in the size and cost of PCs; a switch of emphasis from 【39】______ to linked machines, as evidenced by the growth of local area networks and the Internet; and the spread of computer applications into virtually every 【40】______ of home and business life.
