Does it seem to you that girls have better vocabularies than boys? In your opinion, are boys better at building things? If your answer t

3、o each of those questions is “Yes“, you are right, according to an article in Current Science. There are exceptions, but here are the facts. On the average, males score higher on tests that measure mathematical reasoning, mechanical ability, and problem-solving skills. Females show superior ability

4、in tests measuring vocabulary, spelling and memory. But these differences will probably not always exist. In the future, a persons abilities may not be determined by sex. As one scientist says, “Nothing is impossible for a person to be or do.“ In several recent studies, young babies have been observ

5、ed and tested to discover how different abilities are developed. A scientific team headed by Jerome Kanga, a psychologist at Harvard University, is studying the thinking ability of children 11 months old. The test is a simple one. The baby, while seated on its mothers lap watches “show“ on a small t

6、heater stage. In act 1 of the show, an orange-colored block is lifted from a blue box and moved slowly across the stage. Then it is returned to the box. This is repeated six times. Act 2 is similar, except that the orange block is smaller, but girls immediately become excited and begin to make noise

7、s that sound like language. They seem to be trying to talk. It is known that bones, muscles, and nerves develop faster in baby girls. Usually, too, baby girls talk at an earlier age than boys do. Scientists think there is a physical reason for this. They believe that the nerve endings in the left si

8、de of the brain influences an individuals ability to use words, to spell, and to remember things. By the time they start to school, therefore, little girls have an advantage that boys do not have. Girls are physically more ready to remember facts, to spell, and to read. There, of course, are skills

9、that are important in elementary school. But what have the boys been doing in the years before starting school? They have been developing something called aggression. An aggressive person has courage and energy. He feels strong and independent. He is often the first one to start a fight. What produc

10、es aggression in little boys? It has long been assumed that aggression is caused by male hormones. Scientists today believe that male hormones are not the only part of the explanation, however. They say aggressiveness in boys is also caused by mothers. A team of psychologists discovered this by plac

11、ing mothers and their one-year-old babies in a room filled with toys. The room had a wall through which the scientists could observe what happened without being seen. They took notes on everything the mothers and babies did. Here is a sample of those notes, taken during the observation of a baby boy

12、 and his mother: “Baby leans against mother. Looks up at her, she speaks to him. She turns him around. He walks away, picks up a toy cat, Goes to mother drops the cat, and leans against her. Looks up at her, she turns him around.“ From such observations and from conversations with mother, the scient

13、ists learned something about the treatment of baby boys and baby girls. While the mother keeps her daughter close to her, she unconsciously trains her son to move away from her, to develop independence, and to explore his surroundings. She trains him to become aggressive and to be a problem solver.

14、Consequently, it is easy to understand why little girls often perform school tasks more satisfactorily than boys, especially if the task requires sitting still, obeying few grades. While boys of her age bring home low marks, the girl may easily get good grades. Girls seem to have “better brains“ in

15、school. Why, then, do so few girls become great scientists? Why is the most important thinking in adult society done by men? According to scientists, the answer is aggression. Because boys are aggressive, they refuse to accept other peoples solutions: they insist upon solving problems for themselves

16、. Thus, while little girls are getting high marks in school for remembering what the teacher had told them, little boys are learning to think in more independent ways. In the adult world, the aggressive person is usually the one who gets the big salary, the great responsibility, the powerful job. An

17、d since males are trained at an early age to be aggressive, males are more often chosen for key positions. Many people believe this situation is wrong. They think women could be successful in science and industry if their early training included some “aggression lessons,“ if they were rewarded for i

18、ndependence and problem-solving, as boys are. Furthermore, some psychologists believe that boys may get too much training in aggression. Perhaps little boys should be permitted to learn more on their mothers. It might make them more gentler. The world needs gentleness as much as aggressive strength.

34、 mentally, and(S2) 2 now.

Such thoughts may have (S6) 6 your mind once in a while,

35、 however, If you are in your thirties, forties, fifties, or older, such health related thoughts are likely to become (S7) 7important to you.

37、项 1:_七、Reading Comprehensio(总题数：2，分数：355.00)I was 13 when Benji came into our lives. With his deep brown eyes, floppy ears and cheerful disposition, he was my constant companion throughout my teenage years. We would play together in the garden, and take long walks over the hills behind the house and

38、 being a dog, he seemed to have a sympathy for my problems that went deeper than words could express. He was my best friend. Benji left us about 15 years ago for that great kennel in the sky. But recently Ive been thinking about him a lot. Was he really conscious? Could any animal have consciousness

39、 like we do? Does it matter whether animals are conscious or not? For many, it is a matter of life and death. On the one hand, animal research has helped prevent some of the most pressing human diseases, including hepatitis B, hepatitis C, “mad cow“ disease, malaria, cystic fibrosis and emphysema. O

40、n the other hand, this research is performed largely on chimps, our closest nonhuman relatives, with whom we share 98.4% of our genetic material, and great apes, with whom we are similarly biologically close. Some people feel this connection is strong enough to warrant special treatment. An internat

41、ional group called the Great Ape Project is lobbying the United Nations to adopt a declaration on the rights of great apes modeled on the UN declaration On the Rights of Man. The group believes that apes are “conscious“ and so deserve legal protection of their right to life and freedom from imprison

42、ment and torture. If great apes were shown to have consciousness or something like our own, I would consider it among the scientific discoveries of the century. I would then agree with the Australian philosopher and founder of the animal rights movement, Peter Singer, that per forming medical experi

43、ments on chimps would be like experimenting on orphan children. Thats a pretty chilling thought, and no amount of human suffering saved could justify such an action. But before we close down the laboratories and stop searching for a vaccine against AIDS, we had better take a long hard look at the ev

44、idence for ape consciousness. （分数：177.50）(1).Why does the author bring up the example of Benji?（分数：35.50）A.To show that animals have consciousness.B.To raise the question of animal consciousness.C.Because Benji was his best friend.D.To illustrate the differences between dogs and chimps.(2).What most

45、 likely happened to Benji about 15 years ago?（分数：35.50）A.He ran away.B.He became conscious.C.He died.D.He was the authors best friend.(3).Some people feel that apes should be given special treatment because.（分数：35.50）A.they are genetically similar to humansB.they can help final a cure for “mad cow“

46、diseaseC.they possess a consciousness superior to humansD.they are treated poorly by scientists(4).The Great Ape Project believes that apes deserve legal protection because.（分数：35.50）A.they are very much like humansB.they are conscious of thingsC.they are natural animals and should be protectedD.the

47、y are free from imprisonment ad torture(5).What does the author think about experimenting on apes?（分数：35.50）A.It should be stopped.B.It should not be stopped unless apes are shown to have a consciousness like our own.C.The medical advances gained are outweighed by the suffering of the apes.D.It is a

48、kin to experimenting on orphan children.Not many of the elements occur in nature as pure substances, lying around waiting for someone to pick them up. A few do, and it is not surprising that these were known and collected for various uses in societies around the globe as far back as several thousand years B. C. Sulfur is one of those elements. It was known to burn with smelly results and have an odd appearance. Its use was probably confined to religious ceremonies. Carbon was also known since antiquity, because the charred (烧焦的) b
