The trend of the evidence has been consistent and indicates that there is a serious health risk.

9、 Research teams have conducted studies that show beyond all reasonable doubt that tobacco smoking is associated with a shortened life expectancy.Cigarette smoking is believed by most research workers in this field to be an important factor in the development of cancer of the lungs and cancer of the

10、throat and is believed to be related to cancer of some other organs of the body. Male cigarette smokers have a higher death rate from heart disease than non-smoking males.

Although hot weather just makes most people hot, it can cause medical problems-and death. Health experts say that since

20、 the year 1900, extremely hot weather has killed more people in the United States than any other natural event. One year-the unusually hot summer of 1980-heat caused about 1,700 deaths in the United States. In 1995, more than 600 people died in a similar heat wave in one city-Chicago.To measure extr

21、eme heat, government weather experts have developed the Mean Heat Index. It measures the average of how hot it is felt all day on an extremely hot day.

28、stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu may make a difference in how long the misery lasts.The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys is being able to quickly tell the tw

29、o apart. Thats because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.The common cold and the flu are both caused by viruses. More than 200 viruses can

30、cause cold symptoms, while the flu is caused by three viruses-flu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine (疫苗), which is, for most people, the best way to fight the flu, according to the ALA.But if the flu does strike, quick action can help. A

31、lthough the flu and common cold have many similarities, there are some obvious signs to look for.Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic feature

32、s of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms.The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents

33、to call the doctor if their small children have flu-like symptoms.Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome (综合症), a rare but serious c

Judy Cameron, a scientist at Oregon Health and Science Univ

40、ersity, studies brain development. According to her research, it seems that exercise can make blood vessels, including those in the brain, stronger and more fully developed. Dr. Cameron claims this allows people who exercise to concentrate better. As she says: “While we already know that exercise is

41、 good for the heart, exercise can literally cause physical changes in the brain.“The effects of exercise on brain development can even be seen in babies. Babies who do activities that require a lot of movement and physical activity show greater brain development than babies who are less physically a

42、ctive. With babies, even a little movement can show big results. Margaret Barnes, a pediatrician (儿科医师), believes in the importance of exercise. She thinks that many learning disabilities that children have in elementary school or high school can be traced back to a lack of movement as babies. “Babi

43、es need movement that stimulates their five senses. They need to establish a connection between motion and memory. In this way, as they get older, children will begin to associate physical activity with higher learning, “ says Margaret.Older people can beef up their brains as well. Cornell Universit

44、y studied a group of seniors ranging in age from seventy to seventy-nine. Their study showed a short-term memory increase of up to 40 percent after exercising just three hours a week. The exercise does not have to be very difficult, but it does have to increase the heart rate. Also, just like the mo

45、tion for infants, exercise for older people should involve some complexity. Learning some new skills or motions helps to open up memory paths in the brain that may not have been used for a long time.For most people, any type of physical activity that increases the heart rate is helpful. The main goa

46、l is to increase the brains flow of blood. And your brain can benefit from as little as two to three hours of exercise a week.（分数：15.00）(1).Research by Dr. Cameron seems to suggest that exercise canA. generate new blood vessels.B. change the way a person thinks.C. promote brain development.D. divert

47、 ones attention.（分数：3.00）A.B.C.D.(2).Margaret Barnes thinks that a lack of movement in infancy canA. lead to learning troubles later.B. cause physical disabilities later.C. stimulate the five senses.D. bring about changes in the brain.（分数：3.00）A.B.C.D.(3).The expression “beef up“ in paragraph 3 mean

49、smart people do exercise.B. exercise can be smart or stupid.C. exercise keeps the brain strong.D. it is fashionable to do exercise.（分数：3.00）A.B.C.D.八、第 5部分：补全对话(总题数：1，分数：10.00)Scientists working on a problem do not know and sometimes cant even guess what the final result will be.
