1、Cancer1. Cancer is a group of many related diseases that begin in cells, the body\'s basic building blocks. The body is made up of many types of cells. Normally, cells grow and divide to produce more cells as they are needed to keep the body healthy. Sometimes, this orderly process goes wrong. New cells form when the body does not need them, and old cells do not die when they should. The extra cells form a mass of tissue called a growth or tumor(肿瘤). Benign(良性的) tumors are not cancer. They can often be removed and, in most cases, they do not come back. Malignant (恶性的) tumors are cancer. Cells in malignant tumors are abnormal and divide without control or order.2. Scientists have learned that cancer is caused by changes in genes that normally control the growth and death of cells. Certain lifestyle and environmental factors can change some normal genes into genes that allow the growth of cancer. Many gene changes that lead to cancer are the result of tobacco use, diet, exposure to ultraviolet(紫外线的) radiation from the sun, or exposure to carcinogens (致症物) in the workplace or in the environment. Some gene alterations are inherited.3. Cancer treatment can include surgery, radiation therapy, chemotherapy(化疗), hormone therapy, and biological therapy. The doctor may use one method or a combination of methods, depending on the type and location of the cancer, whether the disease has spread, the patient\'s age and general health and other factors. Because treatment for cancer can also damage healthy cells and tissues, it often causes side effects. Patients and doctors generally discuss the treatment options, weighting the likely benefits of killing cancer cells and the risks of possible side effects.4. Having cancer does not always mean having pain. Whether a patient has pain may depend on the type of cancer, the extent of the disease and the patient\'s tolerance for pain. Most pain occurs when the cancer grows and presses against bones, organs, or nerves. Pain may also be a side effect of treatment. However, pain can generally be relieved or reduced with prescription medicines or over - the - counter drugs recommended by the doctor.Paragraph 2 ______【单选题】

A.How is cancer treated?

B.Does cancer always cause pain?

C.Can cancer be prevented?

D.What is cancer?

E.How common is cancer?

F.What causes cancer?

正确答案:F

答案解析:本题难度也不大，段落主旨句比较明显，是文章第二段的第一句，谈到科学家已查明癌症是由基因变化引起的，基因通常控制着细胞的生长和死亡，回来看选项，F项What causes cancer?简单概括了本段意思，是答案。

2、ExerciseWhether or not exercise adds to the length of life, it is common experience that a certain amount of regular exercise improves the health and contributes a feeling of well-being. Furthermore, exercise which involves play and recreation, and relieves nervous tension and mental fatigue in so doing, is not only pleasant but beneficial.How much and what kind of exercise one should take merits careful consideration. The growing child and the normal young man and young woman thrill with the exhilaration of strenuous sports. They fatigue to the point of exhaustion but recover promptly with a period of rest. But not so with those of middle age and beyond. For them moderation is of vital importance. Just how much exercise a person of a given age can safely take is a question hard to answer. Individual variability is too great to permit of generalization. A game of tennis may be perfectly safe for one person of forty but folly for another. The safe limit for exercise depends on the condition of the heart, the condition of the muscles, the type of exercise, and the regularity with which it is taken. Two general suggestions, however, will serve as sound advice for anyone. The first is that the condition of the heart and general health should be determined periodically by careful, thorough physical examinations. The ____ is that exercise should be kept below the point of physical exhaustion.What type of exercise one should choose depends upon one\'s physical condition. Young people can safely enjoy vigorous competitive sports, but most older persons do bet ter to limit themselves to less strenuous activities. Walking, swimming, skating are among the sports that one can enjoy and safely participate in throughout life. Regularity is important if one is to get the most enjoyment and benefit out of exercise.【单选题】

A.other

B.another

C.one

D.same

正确答案:A

答案解析:前面说到有两个一般性的建议，并且已提到first，那么二者中的另一个用other。

3、The motorcarSome pessimistic experts feel that the automobile is bound to fall into disuse. They see a day in the not-too-distant future when all autos will be abandoned and allowed to rust. Other authorities, however, think the auto is here to stay. They hold that the car will remain a leading means of urban travel in the foreseeable future.The motorcar will undoubtedly. change significantly over the next 30 years. It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types.Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion. One proposed solution to this problem is the automated highway system.When the auto enters the highway system, a retractable (可伸缩的) arm will drop from the auto and make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car\'s movements.The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the highway. The driver will then be free to relax and wait for the buzzer (蜂鸣器) that will warn him of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day highway.In an automated highway system, all the driver needs to do is ____.【单选题】

A.keep in the right lane

B.wait to arrive at his destination

C.keep in constant touch with the computer center

D.inform the system of his destination by phone

正确答案:D

答案解析:文章的最后一段the driver will use a telephone to dial instructions about his destination into system说明本题的答案为D，即在计算机监控系统下，司机所做的不过是通过电话告诉系统自己的目的地而已。

5、The Ideal HusbandScience now might be able to explain women\'s fascination with Brad Pitt\'s face and George Clooney\'s eyes. Women seem to judge potential mate by how masculine their features are, new research shows. Men with square jaws and well-defined brow ridges are seen as good short-term partners, while those with more feminine traits such as a rounder face and fuller lips are perceived as better long-term mates.In the study by Daniel Kruger at the US\'s University of Michigan, 854 subjects viewed a series of male head shots that had been digitally changed to exaggerate or minimize masculine traits. They then . answered questions about how they expected the men in the photos to behave.Most participants said that those with more masculine features were likely to be risky, competitive, and more apt to fight, challenge bosses, cheat on spouses and put less effort into parenting. Those with more feminine faces were seen as good parents and husbands, hard workers and emotionally supportive mates.But, despite all the negative characteristics, when asked who they would choose for a short-term relationship, women selected the more masculine looking men. Brad and George, both chiseled jaws and well-defined brows, then would be good for a brief romance, not for something longer.The study was published in the December issue of the US journal Personal Relationships.Kruger said that from an evolutionary perspective, this makes sense. The key is testosterone, the hormone responsible for the development of masculine facial features and other sexual characteristics. It has been found to affect the body\'s ability to fight disease: men with high levels of the hormone are typically strong and healthy- traits women want to pass on to their children.However, increased testosterone has also been linked to cheating and violence in relationships. So, these men ____ produce high quality offspring, but they don\'t always make great parents or faithful mates, Kruger says.The scientific community have shown skepticism toward physiognomy, which links facial characteristics to certain behavioral traits. But Kruger argues that the research is a valuable tool for understanding mating strategies. And, of course, for explaining why Tony Leung and Takeshi Kanesshiro have millions of female fans. It might have to do with their genes. Or something to do with ours.【单选题】

A.must

B.might

C.have to

D.should

正确答案:B

答案解析:must：必须；might：可能；have to：必须；should：应该。女人根据男人的特征选择伴侣这只是一个因素，因此下结论应该留有余地，用might是比较合适的。
