单选题Cosmetic Surgery Surgery that can improve the way a person looks is becoming more and more popular in the United States. This kind of surgery is called cosmetic surgery, and both men and women are turning to this treatment as a way of keeping their appearance young as well as keeping competitive (有竞争力的) in their jobs. Men especially are beginning to turn to face-lifts (面部拉皮手术), liposuction (taking fat out of the body), and implants (putting artificial parts into their bodies) to help them look younger. As companies downsize (缩编) and move younger employees into higher positions, older employees in their late forties and early fifties fee[ the need to look and act younger in order to stay competitive. These operations are not without dangers, however. One young woman had an eye operation to get rid of the bags under her eyes. She described her experience as terrible. She said, "When he started cutting, I was fully awake. Even though he"d given me an injection near my eyes, I saw everything." She went on to explain, "I knew I had to keep still because of what he was doing. He was scraping (刮) away fat underneath my eyes. It took about ten minutes. After he finished, I felt I couldn"t walk. I was so faint." Her troubles did not end after the operation for two weeks. Her eyes were swollen (肿胀的) and almost completely closed, and even dark glasses could not hide the side effects of the operation. Liposuction, taking fat out of the body, is probably the most popular cosmetic operation in the United States. It seems simple enough. First, a small cut is made over the place where the patient wants the fat removed. Next, a small pipe is put into the cut. A machine like a vacuum cleaner is then used to suck the fat out of the body. However, as one doctor explained, some problems can happen after the operation. He warned: "Irregular lumps and loose skin can result from this operation. If it is not evenly done, liposuction can produce a very lumpy result." Patients often must have more liposuction to correct the problem.

单选题Where Did All the Ships Go? The Bermuda Triangle (三角区) is one 1 the greatest mysteries of the sea. In this triangular area between Florida, Puerto Rico and Bermuda in Atlantic, ships and airplanes 2 to disappear more often than in 3 parts of the ocean. And they do so 4 leaving any sign of an accident or any dead bodies. It is 5 that Christopher Columbus was the first person to record strange happenings in the area. His compass stopped working, a flame came down from the sky, and a wave 100 to 200-feet-high carried his ship about a mile away. The most famous disappearance in the Bermuda Triangle was the US Naval (海军的) Air Flight 19. 6 December 5, 1945, five bomber planes carrying 14 men 7 on a training mission from the Florida coast. Later that day, all communications with Flight 19 were lost. They just disappeared without a trace. The next morning, 242 planes and 19 ships took part in the largest air-sea search in history. But they found nothing. Some people blame the disappearances 8 supernatural (超自然的) forces. It is suggested the 9 ships and planes were either transported to other times and places, kidnapped (绑架) by aliens (外星人) 10 attacked by sea creatures. There are 11 natural explanations, though. The US Navy says that the Bermuda Triangle is one of two places on earth 12 a magnetic compass (指南针) points towards true north 13 magnetic north. 14 , planes and ships can lose their way if they don"t make adjustments. The area also has changing weather and is known 15 its high waves. Storms can turn up suddenly and destroy a plane or ship. Fast currents could then sweep away any trace of an accident.

单选题American Marriage and Family More 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. Moreover, 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 of 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 marriages 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 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. There 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 most of their adult life married.

单选题Mobile Phone and Diseases A study by scientists in Finland has found that mobile phone radiation can cause changes in human cells that might affect the brain, the leader of the research team said. But Darius Leszczynski, who headed the 2-year study and will present findings next week at a conference in Quebec(魁北京), said more research was needed to determine the seriousness of the changes and their impact on the brain or the body. The study at Finland"s Radiation and Nuclear Safety Authority found that exposure to radiation from mobile phones can cause increased activity in hundreds of proteins in human cells grown in a laboratory, he said. "We know that there is some biological response. We can detect it with our very sensitive approaches, but we do not know whether it can have any physiological effects on the human brain or human body," Leszczynski said. Nonetheless the study, the initial findings of which were published last month in the scientific journal Differentiation, raises new questions about whether mobile phone radiation can weaken the brain"s protective shield against harmful substances. The study focused on changes in cells that line blood vessels and on whether such changes could weaken the functioning of the blood-brain barrier, which prevents potentially harmful substances from entering the brain from the bloodstream, Leszczynski said. The study found that a protein called hsp27 linked to the functioning of the blood-brain barrier showed increased activity due to irradiation and pointed to a possibility that such activity could make the shield more permeable(能透过的), he said. "Increased protein activity might cause cells to shrink—not the blood vessels but the cells themselves—and then tiny gaps could appear between those cells through which some molecules could pass." he said. Leszczynski declined to speculate on what kind of health risks that could pose, but said a French study indicated that headache, fatigue and sleep disorders could result. "These are not life-threatening problems but can cause a lot of discomfort," he said, adding that a Swedish group had also suggested a possible link with Alzheimer"s disease. "Where the truth is do not know," he said. Leszczynski said that he, his wife and children use mobile phones, and he said that he did not think his study suggested any need for new restrictions on mobile phone use.
