15、数：15.00)American Marriage and FamilyMore surprising, perhaps, than the current difficulties of traditional marriage is the fact that marriage itself is alive and thriving. As Skolnick notes, Americans are a marrying people: relative to Europeans, more of us marry and we marry at a younger age. Moreo

16、ver, after a decline in the early 1970s, the rate of marriage in the United States is now increasing. Even the divorce rate need to be taken in this pro-marriage context: some 80 percent of divorced individuals remarry. Thus marriage remains, by far, the preferred way of life for the vast majority o

17、f people in our society. What has changed more than marriage is the nuclear family. Twenty-five years ago, the typical American family consisted of a husband, a wife, and two or three children. Now, there are many marriages in which couples have decided not to have any children. And there are many m

18、arriages where at least some of the children are from the wife“s previous marriages, of the husband“s, or both. Sometimes these children spend all of their time with one parent from the former marriage; sometimes they are shared between the two former spouses Thus, one can find every type of family

19、arrangement. There are marriages without children; marriages with children from only the present marriage; marriages with “full-time“ children from both the present and former marriages; marriages with “full-time“ children from the present marriage and “part-time“ children from former marriages. The

20、re are stepfathers, stepmothers, half-brothers, and half-sisters. It is not all that unusual for a child to have four parents and grandparents! These are enormous changes from the traditional nuclear family. But even so, even in the midst of all this, there remains one constant, most Americans spend

New cell phones

26、and personal computers get smaller every year, which means these electronics require even smaller components on the inside. Engineers are looking for creative ways to build these components, and they“ve turned their eyes to graphene, a superthin material, made of carbon, that could change the future

27、 of electronics. This year“s Nobel Prize for Physics has been awarded to Andre Geim and Kostya Novoselov from the University of Manchester, UK. for the discovery of graphene. Graphene isn“t just small, it“s “the thinnest possible material in this world,“ says Novoselov. He calls it a “wonder materia

28、l.“ It“s so thin that you would need to stack about 25,000 sheets just to make a pile as thick as a piece of ordinary white paper. If you were to hold a sheet of graphene in your fingers, you“d have no idea because you wouldn“t be able to see it. Carbon is one of the most abundant elements in the un

29、iverse. Every known kind of life contains carbon. Graphene is a sheet of carbon, but only one atom thick. You don“t have to look far to find grapheneit“s all around you. If you want this high-tech wonderstuff, all you need is a pencil, paper and a little adhesive tape. Use the pencil to shade a smal

30、l area on the paper, and then apply a small piece of adhesive tape over the area. When you pull up the tape, you“ll see that it pulls up a thin layer of some of the shading from your pencil. That layer is called graphite, one of the softest minerals in the world. Now stick the same piece of tape on

31、another sheet of paper and pull the tape upthere should be an even thinner layer, this time left on the paper. Now imagine that you do this over and over, until you get the thinnest possible layer of material on the paper. This layer would be only one atom thick, and you wouldn“t be able to see it.

32、Graphite is made of layers of graphene, so when you get to the thinnest possible layer, you“ve found graphene.（分数：15.00）(1).What would change the future of electronics according to engineers?（分数：3.00）A.Creative ways.B.Big technology.C.Both A and .D.Graphene.(2).According to the second and third para

33、graphs, what is true of graphene?（分数：3.00）A.It can be used to make paper.B.It is easy to find graphene.C.It is possibly the thickest material in the world.D.It is possible to see it with our naked eye.(3).Which of the following can be used to replace the word “apply“ in paragraph 4?（分数：3.00）A.use.B.

34、polish.C.request.D.put.(4).Which of the following is NOT meant in the last two paragraphs?（分数：3.00）A.With a pencil, a sheet of paper and a piece of adhesive tape, we can find graphene.B.Graphite is made of layers of graphene, the thinnest material in the world.C.Graphene is made of graphite, one of

35、the softest materials in the world.D.When we get to the thinnest possible layer of graphite, we find graphene.(5).Graphene“s superstrength lies in the fact that _.（分数：3.00）A.It is made of the most abundant elements in the worldB.It can help to make electronic components smallerC.It is the thinnest m

36、aterial in the worldD.It helps engineers to produce more sensitive electronic products八、第五部分：补全短文(总题数：1，分数：10.00)UV Light Causes Skin CancerDon“t laugh if you hear about kids hiding in their basement this summer. They might have been frightened by a recent report from Europe that liquid sunscreens d

37、on“t protect people from the sun“s harmful rays. Researchers kept track of 631 children, some of whom used sunscreen and 1 . The researchers found that the kids who used sunscreen got more sun-caused moles than did the kids who didn“t use sunscreen. Kids with sun-caused moles are more likely to deve

38、lop skin cancer later in life. Did sunscreen harm the children? Probably not, the researchers concluded. They believe that the children relied too much on their sunscreen and stayed in the sun too long. Sunscreen is still safe to use, say skin experts, as tong as it is used sensibly. Solar Cares Usi

39、ng sunscreen sensibly is more important than ever. Why? Skin experts like Martin Weinstock believe that 2 . Earth“s ozone layer appears to be getting thinner. Ozone is a gas. In the upper atmosphere, ozone blocks much of the sun“s harmful ultraviolet (UV) radiation. Polluting chemicals are thought t

40、o be destroying the ozone in some places. Even though the world“s wealthy countries agreed to stop making polluting chemicals a few years ago, ozone is still disappearing. And that“s bad news, skin experts say, because UV light causes skin cancer, and skin cancer is the most common kind of cancer in

41、 the United States. More than a million new cases of skin cancer are showing up in the United States every year. Scientists are looking at kids to reverse that trend. Why? Because getting too much sun when you“re a kid seems to set the stage for getting skin cancer when (48. . According to Weinstock

42、, three-quarters of all skin cancers might never develop if people under the age of 18 avoided overexposure to the sun. Glaring Facts What happens when skin meets sun? Light rays, which come in varying wavelengths, strike the skin. Visible light consists of wavelengths 3 . Ultraviolet light consists

43、 of waves too short to be seen. UV light comes in several varieties, among them UVB and UVA. UVB wavelengths are slightly shorter than UVA wavelengths. Scientists once thought that UVB light was harmful and that UVA light produced a healthful tan. But opinions have changed. Scientists still agree th

44、at UVB light causes sun burns. But now they suspect that both kinds of UV light damage the DNA of cells. Moreover, scientists believe that either UVA light or UVB light or both weaken the body“s disease-fighting immune system. The body becomes less capable of repairing damaged cells, and such cells

45、may go on to divide uncontrollably. In other words, 4 Three Little Words To help people avoid getting harmed by the sun, the American Cancer Society has summed up its advice in three words. Slip, Slop and Slap. The words are short for “Slip on a shirt! Slop on the sunscreen! Slap on a hat!“ A. they

46、may become cancerous B. people can see C. you“re older D. UVA is different from UVB E sunlight is growing more hazardous F some of whom didn“t（分数：10.00）九、第六部分：完形填空(总题数：1，分数：15.00)Hospital MistreatmentAccording to a study, most medical interns report experiencing mistreatment, including humiliation b

47、y senior doctors, 1 threatened, or physical abuse in their first year out of medical school. The findings come from analysis of the 2 a 13-page survey mailed in January 1991 to 1,733 second-year residents. The survey and 3 appear in the April 15th issue of the Journal of the American Medical Associa

48、tion. Overall, out of the 1,277 residents 4 completed surveys, 1,185 said that they had experienced at least one incident of mistreatment in their intern year. 5 reporting incidents where they were abused, more than 45% of the residents said they had witnessed at least one incident where other perso
