25、osity（C） frankness（D）skillfulness 一、Part Cloze50 There are only three available strategies for controlling cancer: prevention, screening and treatment. Lung cancer causes more deaths than any other types of cancer. A major cause of the disease is not【C1】_known; there is no good evidence that screeni
26、ng is much help; and treatment fails in about 90 percent of all cases. At present, therefore, the main strategy must be【C2】_. This may not always be true, of course, as for some other types of cancer, researches over the past few decades have produced (or suggested) some importance in prevention, sc
27、reening or treatment. 【C3 】_, however, we consider not what researchers may one day offer but what todays knowledge could already deliver that is not being delivered, then the most practical and cost-efficient opportunities for avoiding premature death from cancer, especially lung cancer, probably i
28、nvolve neither screening nor improved【C4】_, but prevention. This conclusion does not depend on the unrealistic assumption that we can eliminate tobacco. It merely assumes that we can reduce cigarette sales appreciably by raising prices or by【 C5】_on the type of education that already appears to have
29、 a positive effect on cigarette assumption by white-collar workers and that we can substantially reduce the amount of tar【C6 】_per cigarette. The practicability of preventing cancer by such measures applies not only in those countries, such as, the United States of America, because cigarette smoking
30、 has been common for decades, 25 to 30 percent of all cancer deaths now involves lung cancer, but also in those where it has become【C7】_only recently. In China, lung cancer as yet accounts for only 5 to 10 percent of all cancer deaths. This is because it may take as much as half a century for the ri
31、se in smoking to increase in the incidence to lung cancer. Countries where cigarette smoking is only now becoming widespread can expect enormous increase in lung cancer during the 1990s or early in the next century, 【C8】_prompt effective action is taken against the habitindeed, such increase is alre
32、ady plainly evident in parts of the world. There are reasons why the preventions of lung cancer is of such overwhelming importance. First, the disease is extremely common, causing more deaths than any other types of cancer now【C9】_: secondly, it is generally incurable; thirdly, effective, practicabl
33、e measures to reduce its incidence are already reliably known; and finally, reducing tobacco consumption will also have a substantial【C10】_on many other diseases.51 【C1 】（A）hardly（B） never（C） less（D）reliably52 【C2 】（A）treatment（B） cure（C） prevention（D）diagnosis53 【C3 】（A）Although（B） If（C） Since（D）Un

Giving up smoking is one of obvious ways to reduce the risk, but another answer may lie in the kitc
36、hen. According to a new report, even heavy smokers may be protected from developing lung cancer by eating a daily portion of carrots, spinach or any other vegetable or fruit containing a form of vitamin A called carotene. The finding, published in THE LANCET, is part of a long-range investigation of
37、 diet and disease. Since 1957, some American researchers have monitored the dietary habits and medical histories of 2, 000 middle-aged men employed by the Western Electric Co. in Chicago. Led by Dr. Richard Shekelle of St. Lukes Medical Center, the researchers recently began to sort out the links be
38、tween the subjects dietary patterns and cancer. Other studies of animals and humans have suggested that vitamin A offer some protection against lung cancer. The correlation seemed logical, explains Shekelle, since vitamin A is essential for the growth of the epithelial tissue that lines the airways
39、of the lungs. Vegetables: But the earlier research did not distinguish between the two different forms of the vitamin. “Preformed“ vitamin A, known as retinols found mainly in liver and dairy products like milk, cheese, butter and eggs. But vitamin A is also made in the body from carotene, which is
40、abundant in a variety of vegetables and fruits, including carrots, spinach, squash, tomatoes, sweet potatoes and apples. In the study, Shekelle and his colleagues found little correlation between the incidence of lung cancer and the consumption of foods containing preformed vitamin A. But when they
41、examined the data on carotene intake, they discovered a significant relationship. Among the 488 men who had the lowest level of carotene consumption, there were 14 cases of lung cancer; in a group of the same size that ate the most carotene, only two cases developed. The apparent protective effect o
42、f carotene held up even for long-time smokersbut to a lesser degree. Further studies will be necessary before the link between lung cancer and carotene can be firmly established. In the meantime, researchers warn against taking large numbers of vitamin A pills, because the tablets contain a form of
43、the chemical that can be extremely toxic in high doses. Instead, they advise a well-balanced diet that includes goods rich in carotene. For a smoker, a half-cup of carrots every day might possibly make the difference between life and death.61 The word “malignancy“ (Line 1, Para. 1) most probably ref
44、ers to_.（A）cancer（B） sickness（C） vitamins（D）disease62 Preformed vitamin A is NOT found in_.（A）milk（B） eggs（C） apples（D）cheese63 Carotene is present in all of the following EXCEPT_.（A）tomatoes（B） carrots（C） squash（D）butter64 Among the groups studied, who had the most cases of lung cancer?（A）Those wit
45、h the lowest level of carotene intake.（B） Those with the highest level of carotene intake.（C） Those who ate only foods containing carotene.（D）Those with the lowest intake of carrots. 65 What is needed to establish firmly the link between carotene and lung cancer?（A）Further study.（B） More money.（C） M
46、ore cases of lung cancer.（D）More people willing to eat carrots. 65 Technically, any substance other than food that alters our bodily or mental functioning is a drug. Many people mistakenly believe the term drug refers only to some sort of medicine or an illegal chemical taken by drug addicts. They d
47、ont realize that familiar substances such as alcohol and tobacco are also drugs. This is why the more neutral term substance is now used by many physicians and psychologists. The phrase substance abuse is often used instead of drug abuse to make clear that substances such as alcohol and tobacco can
48、be just as harmfully misused as heroin and cocaine. We live in a society in which the medicinal and social use of substances (drugs) is pervasive: an aspirin to quiet a headache, some wine to be sociable, coffee to get going in the morning, a cigarette for the nerves. When do these socially acceptab
49、le and apparently constructive uses of a substance become misuses? First of all, most substances taken in excess will produce negative effects such as poisoning or intense perceptual distortions. Repeated use of a substance can also lead to physical addiction or substance dependence. Dependence is marked first by an increased tolerance, with more and more of the substance required to produce the desired effect, and then by the appearance of unpleasant wi
