【文章內(nèi)容簡(jiǎn)介】 He wakes up in the morning and summons the rest of the world to its tasks. He cries, and someone es to attend to him. When he is hungry, people feed him, and when he is wet, people change him. Very often, we do not pletely outgrow that infantile notion that our wishes cause things to happen.26. What is said about the two deceased elderly women?A) They lived out a natural life.B) They died due to lack of care by family members.C) They died of exhaustion after the long plane ride.D) They weren’t accustomed to the change in weather.(A)27. The author had to conduct the two women’s funerals probably because ________.A) he had great sympathy for the deceasedB) he wanted to console the two familiesC) he was priest of the local churchD) he was an official from the munity(C)28. People feel guilty for the deaths of their loved ones because ________.A) they believe that they were responsibleB) they had neglected the natural course of eventsC) they couldn’t find a better way to express their griefD) they didn’t know things often turn out in the opposite direction(A)29. In the context of the passage, “... the world makes sense” (Line 2, Para, 4) probably means that ________.A) we have to be sensible in order to understand the worldB) everything in the world is predeterminedC) there’s an explanation for everything in the worldD) the world can be interpreted in different ways(C)30. People have been made to believe since infancy that ________.A) every story should have a happy endingB) their wishes are the cause of everything that happensC) life and death is an unsolved mysteryD) everybody is at their mand(B)Passage ThreeQuestions 31 to 35 are based on the following passage.“I’ve never met a human worth cloning,” says cloning expert Mark Westhusin from his lab at Texas Aamp。M University. “It’s a stupid endeavor.” That’s an interesting choice of adjective, ing from a man who has spent millions of dollars trying to clone a 13yearold dog named Missy. So far, he and his team have not succeeded, though they have cloned two cows and expect to clone a cat soon. They just might succeed in cloning Missy this spring—or perhaps not for another 5 years. It seems the reproductive system of man’s best friend is one of the mysteries of modern science.Westhusin’s experience with cloning animals leaves him upset by all this talk of human cloning. In three years of work on the Missy project, using hundreds upon hundreds of dog’s eggs, the Aamp。M team has produced only a dozen or so embryos (胚胎) carrying Missy’s DNA. None have survived the transfer to a surrogate (代孕的) mother. The wastage of eggs and the many spontaneously aborted fetuses (胎) may be acceptable when you’re dealing with cats or bulls, he argues, but not with humans. “Cloning is incredibly inefficient, and also dangerous,” he says.Even so, dog cloning is a mercial opportunity, with a nice research payoff. Ever since Dolly the sheep was cloned in 1997, Westhusin’s phone has been ringing with people calling in hopes of duplicating their cats and dogs, cattle and horses. “A lot of people want to clone pets, especially if the price is right,” says Westhusin. Cost is no obstacle for Missy’s mysterious billionaire owner。 he’s put up $ million so far to fund Aamp。M’s research.Contrary to some media reports, Missy is not dead. The owner wants a twin to carry on Missy’s fine qualities after she does die. The prototype is, by all accounts, athletic, goodnatured and supersmart. Missy’s master does not expect an exact copy of her. He knows her clone may not have her temperament. In a statement of purpose, Missy’s owner and the Aamp。M team say they are “both looking forward to studying the ways that her clones differ from Missy.”Besides cloning a great dog, the project may contribute insight into the old question of nature vs, nurture. It could also lead to the cloning of special rescue dogs and many endangered animals.However, Westhusin is cautious about his work. He knows that even if he gets a dog pregnant, the offspring, should they survive, will face the problems shown at birth by other cloned animals: abnormalities like immature lungs and heart and weight problems~ “Why would you ever want to clone humans,Westhusin asks, “when we’re not even close to getting it worked out in animals yet?”31. By “stupid endeavor” (Line 2, Para. 1), Westhusin means to say that ________.A) human cloning is a foolish undertakingB) animal cloning is absolutely impracticalC) human cloning should be done selectivelyD) animal cloning is not worth the effort at all(A)32. What does the first paragraph tell us about Westhusin’s dog cloning project?A) Its success is already in sight.B) It is doomed to utter failure.C) It is progressing smoothly.D) Its oute remains uncertain.(D)33. By cloning Missy, Mark Westhusin hopes to ________.A) examine the reproductive system of the dog speciesB) find out the differences between Missy and its clonesC) search for ways to temperamentD) study the possibility of cloning humans(B)34. We learn from the passage that animal clones are likely to have ________.A) an abnormal shapeB) a bad temperC) defective organsD) immune deficiency(C)35. It can be seen that present cloning techniques ________.A) provide insight into the question of nature vs, nurtureB) have been widely used in saving endangered speciesC) have proved quite adequate for the cloning of humansD) still have a long way to go before reaching maturity(D)Passage FourQuestions 36 to 40 are based on the following passage.Frustrated with delays in Sacramento, Bay Area officials said Thursday they planned to take matters into their own hands to regulate the region’s growing pile of electronic trash.A San Jose councilwoman and a San Francisco supervisor said they would propose local initiatives aimed at controlling electronic waste if the California lawmaking body fails to act on two
