摘要： In the last sentence of paragraph 2 the phrase “the practical results refers to the results . A. that are obtained from experience B．that can be learned as knowledge C. that can be made use of D．helping us make further exploration B Scientists have identified a genethat plays a role in violence in men ill-treated in childhood. The discovery could explain why some survive unhappy childhoods and go on to normal lives, while others turn to violence, crime or antisocial behavior. But it will also restart the argument about the influence of nature and nurturein criminal behavior. Terrie Moffitt and Avshalom Caspi report in Science today that one common form of a gene in the brain makes men more likely to be violent-but only if they have experienced cruelty or rejection in childhood. The researchers followed up the life histories of 442 boys born in New Zealand in 1972. Of these, 154 had been ill-treated in the first 10 years, 33 of them severely. They had either experienced sexual attack, beatings or rejection by mother or stepparents. Of the 154 children, 55 had a less active variantof a gene called MAOA, which controlled the balance of neurotransmittersin the brain, and 99 had the more active variant. The 55 boys were more than twice as likely to have been involved in criminal behavior than the other ill-treated group. They made up 12% of the total, but were responsible for 44% of all crimes committed among the 442 boys. Prof Moffitt stressed a “violence gene had not been discovered. Boys with the less active form who were not ill-treated during childhood lived perfectly normal lives. “It is very common in the population. One third of us have it, she said. “So the gene apparently doesn’t do much of anything, it doesn’t cause an obstacle in any way, unless we are also ill-treated. The gene might also indicate the ability to endure mental stress. The military or the police might examine applicants to see if they have the more active form. But the discovery also raises the view of biology as fate, and the argument that people with the less active form of the gene could be social risks, to be treated with drugs. “This research can easily play into the tendency to fix social problems through medical treatment, said David King of the UK Gene Alert Group.

B

   The desire to make explorations is born with man. Wherever his imagination goes, man also has a strong wish to go. A large part of human history is connected with the exploration of the world in which we live. Again and again people have set out with surprising courage and patience to look into unknown regions(地区) and lands to see what had not yet been seen. With kites, balloons and aircraft they left the ground to pass through the lower atmosphere. Now the outer space receives their attention.

Why should man take the trouble of(不怕麻烦) conquering(征服) space? It is hard to list the specific practical benefits that will result in. But one knows, from past experience in other areas, that man will surely see and discover new things in space that will increase our scientific knowledge, and this new knowledge will find its way into valuable practical uses. What we learn about man himself, from his experience in space, and from the effects of space and the space flight environment on him, will be extremely valuable. The new techniques developed to carry out the exploration of space, and to keep man alive in space, will certainly find practical uses in everyday life in some way. The areas that will benefit are manifold.They include communication, transportation and travel, food production, materials, fuels and many others. But to say definitely(肯定地) just what the practical results will be is almost impossible.
