Section A (15) Directions: For each blank in the following passage there are four words or phrases marked A, B, C and D.Fill in each blank with the word or phrase that best fits the context. Nothing seems more inevitable than aging and death ---- not even taxes.Every plant, animal and person you have ever seen will 50 die.But some recent research suggests that aging as we know it may not be inevitable.Indeed, as our 51 of it grows, aging can be seen not as an unchangeable reality from which there is no escape, but as the product of biological processes that we may be able to 52 someday. We already know that some animals do not seem to age.Many cold-water ocean fish and some amphibians never 53 a fixed size; they continue to grow bigger, to be able to reproduce and to live until something kills them.What these 54 seem to be telling us is that something in their genes ---- and possibly in ours ---- controls the 55 of aging, and that aging is not the fate of every living thing. 56 the history of life on earth, one of the most common difficulties that animals have faced has been a lack of food.About 70 years ago, scientists discovered that when animals are forced to live on 30 to 40 percent fewer calories than they would 57 eat, something unusual happens: they become 58 to most age-related diseases ---- cancer, heart disease, diabetes ---- and live 30 to 50 percent longer.Restricting calories 59 aging.But what are the 60 genes that preserve vitality and starve off diseases? About 15 years ago, armed with powerful new molecular-research techniques, a few scientists began to 61 these genetic phenomena.They have discovered that a gene called Sir2 ---- which is present in all animals, including humans ---- is 62 for the health benefits of calorie restriction, perhaps by repairing our DNA.But if we had to restrict our calorie intake by 30 to 40 percent, would it be of any 63 use? Few of us would be capable of restricting our diets so severely that we were constantly 64 : whether or not it made life longer, it would surely make life feel longer. 50.A.suddenly B.eventually C.separately D.unexpectedly 51.A.desire B.feeling C.dream D.understanding 52.A.develop B.design C.control D.solve 53.A.reach B.acquire C.need D.display 54.A.objects B.samples C.items D.creatures 55.A.nature B.system C.pace D.condition 56.A.Through B.Throughout C.Beyond D.Across 57.A.rarely B.occasionally C.normally D.mainly 58.A.resistant B.similar C.essential D.accessible 59.A.quickens B.slows C.avoids D.overcomes 60.A.horrible B.extra C.specific D.original 61.A.investigate B.illustrate C.record D.prove 62.A.famous B.generous C.responsible D.convenient 63.A.fashionable B.practical C.immediate D.daily 64.A.happy B.depressed C.hungry, D.scared Section B (30) Directions: Read the following passages.Each passage is followed by several questions or unfinished statements.For each of them there are four choices marked A, B, C and D.Choose the one that fits according to the information given in the passage you have just read.A Unless we spend money to spot and prevent asteroids now, one might crash into Earth and destroy life as we know it, say some scientists. Asteroids are bigger versions of the meteoroids that race across the night sky.Most orbit the sun far from Earth and don’t threaten us.But there are also thousands of asteroids whose orbits put them on a collision course with Earth. Buy $50 million worth of new telescopes right now.Then spend $10 million a year for the next 25 years to locate most of the space rocks.By the time we spot a fatal one, the scientists say, we’ll have a way to change its course. Some scientists favor pushing asteroids off course with nuclear weapons.But the cost wouldn’t be cheap. Is it worth it? Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs.Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years.Sounds pretty rare-but if one did fall, it would be the end of the world.“If we don’t take care of these big asteroids, they’ll take care of us, says one scientist.“It’s that simple. The cure, though, might be worse than the disease.Do we really want fleets of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday rocks than from a great nuclear fleet set against them, said a New York Times article. 65.What does the passage say about asteroids and meteoroids? A.They are heavenly bodies different in composition. B.They are heavenly bodies similar in nature. C.There are more asteroids than meteoroids. D.Asteroids are more mysterious than meteoroids. 66.What do people think of the suggestion of using nuclear weapons to alter the courses of asteroids? A.It sounds practical but it may not solve the problem. B.It may create more problems than it might solve. C.It is a waste of money because a collision of asteroids with Earth is very unlikely. D.Further research should be done before it is proved applicable. 67.We can conclude from the passage that . A.while pushing asteroids off course nuclear weapons would destroy the world B.asteroids racing across the night sky are likely to hit Earth in the near future C.the worry about asteroids can be left to future generations since it is unlikely to happen in our lifetime D.workable solutions still have to be found to prevent a collision of asteroids with Earth 查看更多

“Leave him alone,” I shouted as I walked out of the orphanage(孤儿院) gate and saw several of the Spring Park School bullies(欺负弱者的人) pushing the deaf kid around.

I had seen him on his front covered entrance several times doing absolutely nothing, except just sitting there making funny hand movements.

In the summer time we didn’t get much to eat  38  Sunday supper, except watermelon and then we had to eat it behind the dining room so we would not make a mess on the  39  inside.

Though the bus stopped about two miles from home, Dad never met me, even in bad weather. So when I went away to college, I knew I was in for a long  36  whenever I came home.
