Since Scottish scientists reported that they had managed to clone a sheep named Dolly in 1997, researc
17、h into cloning has grown rapidly. In May l998, scientists in Massachusetts managed to create two identical calves using cloning technology. A mouse has also been cloned successfully. But the debate over cloning humans really started when Chicago physicist Richard Seed made a surprising announcement:
18、 We will have managed to clone a human being within the next two years, he told the world.2 Seeds announcement provoked a lot of media attention, most of it negative. In Europe, nineteen nations have already signed an agreement banning human cloning and in the US the President announced: We will be
19、introducing a law to ban all human cloning and many states in the US will have passed anti-cloning laws by the end of the year.3 Many researchers are not so negative about cloning. They are worried that laws banning human cloning will threaten important research. In March, the New England Journal of
20、 Medicine called any plan to ban research on cloning humans seriously mistaken. Many researchers also believe that in spite of attempts to ban it, human cloning will have become routine by because it is impossible to stop the progress of science.4 Is there reason to fear that cloning will lead to a
21、nightmare world? The public has been bombarded with newspaper articles, television shows and films, as well as cartoons. Such information is often misleading, and makes people wonder what on earth the scientists will be doing next.5 Within the next five to ten years scientists will probably have fou

25、 carrying a person unveiled on Friday in Tokyo, Japan. Its creators at Waseda University in Tokyo and the Japanese robotics company Tmsuk hope their two-legged creation will one day enable wheel-chair users to climb up and down stairs and assist the movement of heavy goods over uneven terrain.The ba
26、ttery-powered robot, code-named WL-16, is essentially an aluminum chair mounted on two sets of telescopic poles. The poles are bolted to flat plates which act as feet. WL-6 uses 12 actuators to move forwards, backwards and sideways while carrying an adult weighing up to 60 kilograms(130 pounds). The
27、 robot can adjust its posture and walk smoothly even if the person it is carrying shifts in the chair. At present it can only step up or down a few mil1imeters, but the team plans to make it capable of dea1ing with a normal flight of stairs.I believe this bipedal robot, which I prefer to call a two-
28、legged walking chair rather than a wheel-chair, will eventually enable people to go up and down the stairs, said Atsuo Takanishi, from Waseda UniversityWe have had strong robots for some time but usually they have been manipulators, they have not been geared to carrying people around, says Ron Arkin
29、, at the Georgia Institute of Technology and robotics consultant for Sony. But I dont know how safe and how user-friendly WL- 16 is.Tmsuk chief executive Yoichi Takamoto argues that bipedal or multi-legged robots will be more useful than so-called caterpillar models for moving over uneven ground.WL-
30、 16s normal walking stride measures 30 centimeters, but it can stretch its legs to 136 cm apart. The prototype is currently radio-controlled, but the research team plans to equip it with a stick-like controller for the user in future, Takanishi said, it wi1l take at least two years to develop the WL
31、- 16 prototype into a working model.Smaller, ground-hugging robots have been developed to pass across tricky terrain. One maggot-like device uses a magnetic fluid to pulse its way along, while another snake-like robot uses smart software to devise new movement strategies if the landscape takes its t

37、he nest. This behavior is interesting to scientists, who wonder how ants know for sure - and so soon-that another ant is dead.Dong-Hwan Choe, a scientist at the University of California found that Argentine ants have a chemical on the outside of their bodies that signals to other ants, Im dead - tak
38、e me away.But theres a twist to Choes discovery. These ants are a little bit like zombies. Choe says that the living ants - not just the dead ones - have this death chemical. In other words, while an ant crawls around, perhaps in a picnic or home, its telling other ants that its dead.What keeps ants
39、 from hauling away the living dead? Choe found that Argentine ants have two additional chemicals on their bodies, and these tell nearby ants something like, wait -Im not dead yet. So Choes research turned up two sets of chemical signals in ants: one says, Im dead, the other set says, Im not dead yet
40、.Other scientists have tried to figure out how ants know when another ant is dead. If an ant is knocked unconscious, other ants leave it alone until it wakes up. That means ants know that unmoving ants can still be alive.Choe suspects that when an Argentine ant dies, the chemical that says Wait - Im
41、 not dead yet quickly goes away. Once that chemical is gone, only the one that says Im dead is left. Its because the dead ant no longer smells like a living ant that it gets carded to the graveyard, not because its body releases new unique chemicals after death, said Choe. When other ants detect the
42、 dead chemical without the not dead yet chemical, they haul away the body. This was Choes hypothesis.To test his hypothesis, Choe and his team put different chemicals on Argentine ant pupae. When the scientists used the Im dead chemical, other ants quickly hauled the treated pupae7 away. When the sc
43、ientists used the Wait - Im not dead yet chemicals, other ants left the treated pupae alone. Choe believes this behavior shows that the not dead yet chemicals override the dead chemical when picked up by adult ants. And that when an ant dies, the not dead yet chemicals fade away. Other nearby ants t
44、hen detect the remaining dead chemical and remove the body from the nest.36.What is meant by death chemical mentioned in paragraph 3?A.A chemical that contains poison.B.A chemical that causes death.C.A chemical that announces death.D.A chemical that prevents death.37.Which of the following is closes
45、t in meaning to the question What keeps ants from hauling away the living dead? (paragraph 4)?A.How do ants know what is to be hauled away from the dead ants?B.What prevents ants from removing the ants that are not yet dead?C.What do ants do to keep themselves away from the dying ants?D.What prevent
46、s ants from being carried away after they die.38.What is NOT true about Choes finding?A.When an ant dies, it produces a I am dead signal.B.Living ants have the death chemical on their bodies.C.Ants have two sets of chemicals on theft bodies.D.Ants have the I am not dead chemical on their bodies.39.According to Choes hypothesis,A.an ant still smells like a living when it dies.B.the I am dead chemical leaves the ants body when it dies.C.the I am not dead yet chemical is left when an ant dies.D.the I am not dead yet chemical leave
