W: Did you know it was going to rain todayM: Absolutely not. This comes as a big shock to me, especially since the paper says mostly sunny.W: Well, I guess the paper must have meant mostly sunny somewhere else. But since we’ve come out this way, why don’t we just move the blanket under that treeM: That’s a good idea. It looks like it’s still dry there, as long as it doesn’t start to come down any harder.W: You didn’t happen to bring us a spare blanket, did you Because this one is all wet now.M: No. But I do have some folding stools in the car. Will they doW: They’ll be just fine. I’m really hungry. So while you’re there, how about bringing out the foodM: I thought you were bringing the food.W: This is unbelievable. If I weren’t so hungry, this would be really funny. So what nowM: What’s the name of the restaurant which you like so much What will the speakers probably do next().
Andrena Gravida is the name of a wild bee declining in the United Kingdom and the Netherlands. A (31) of months ago the recent drop in migratory bird populations was known, based on a study (32) in the Netherlands. Now there’s more troubling news from that part of the world: a study released today by the journal Science reports that there’s been a dramatic loss of (33) among wild bees over the past 25 years in Holland.There’s (34) to a 70% decline in the variety and (35) of bee (36) in some areas in Britain. A loss of biodiversity is more subtle (37) an overall drop in absolute numbers of (38) or plants, but it’s still (39) a problem because the (40) species in an ecosystem, the more the system (41) on each one of them, and if disease or some other (42) wipes out a species, its function could go unfilled. In the (43) of bees, that (44) is to pollinate plants, both wild and crop plants. And (45) the authors of the study show, there’s been a (46) decline in plants that were once pollinated (47) the disappearing bees. Indeed, it isn’t clear (48) came first, the plant decline or the decline in bees. It’s also not clear (49) any crops are in trouble, only that there’s a potential for it if this trend continues. It’s also not clear (50) it’s happening. Climatic changes caused by global warming are a possibility, but so is the destruction of wild habitat in both countries, as population and industry both expand. 31().
During the Christmas shopping rush in London, the intriguing story was reported of a tramp who, apparently through no fault of his own, found himself locked in a well-known chain store late on Christmas Eve. No doubt the store was filled with last-minute Christmas shoppers and the staff were dead beating and longing to get home. Presumably all the proper security checks were made before the store was locked and they left to enjoy the three-day holiday untroubled by customers desperate to get last-minute Christmas presents.However that may be, our tramp found himself alone in the store and decided to make the best of it. There was food, drink, bedding and camping equipment, of which he made good use. There must also have been television sets and radios. Though it was not reported if he took advantage of these facilities, when the shop re-opened, he was discovered in bed with a large number of empty bottles beside him. He seems to have been a man of good humour and philosophic temperament—as indeed vagrants very commonly are. Everyone else was enjoying Christmas, so he saw no good reason why he should not do the same. He submitted, cheerfully enough, to being taken away by the police. Perhaps he had had a better Christmas than usual. He was put into prison for seven days. The judge awarded no compensation to the chain store for the food and drink our tramp had consumed. They had, in his opinion, already received valuable free publicity from the coverage the story received in the newspapers and on television. Perhaps the judge had a good Christmas too. What action did the tramp take().
W: Hi! Paul. All set for your speech club presentation this eveningM: Yes, I’m going to discuss robots.W: Robots You mean, those machines that walk and talk like in the moviesM: No, industrial robots, like those used in the automotive and electronics industries.W: I saw an article about that kind of robot the other day. There were pictures of robots welding cars, but they certainly didn’t look the way I thought robots should look.M: The robots we usually imagine are made up in science fiction. In industry, robots are designed to do a specific set of operations such as welding car frames. They are rarely built to resemble humans.W: Actually, all they need is a kind of brain to give signals and a mechanism such as an arm to carry out instructions, rightM: Right! Tiny computers become the brains of these robots. The computer sends signals in the form of electrical impulses that move an arm and a claw. The claw is the hand that does a particular kind of work. Some new industrial robots can reach to a number of tasks and it’s easy to reprogram them to perform totally different operations. That’s one reason why they’re becoming so popular.W: They increase productivity, don’t they I mean that even though they’re still quite expensive, they often cost less time doing the same job. I imagine robot will be used more and more.M: Exactly. So now that you know all about the next industrial revolution, you don’t have to come to speech club tonight. Where is the man going to make a presentation().
