Lack of exercise is considered a risk factor for cancer. There is considerable evidence that inactivity is connected with increased risk for lung cancer, breast cancer, etc.
In the Aerobics Center Longitudinal Study, more than 32,000 people (25,000 men and 7,000 women) were given a preventive medical examination that included a machine exercise test to measure physical fitness. They were given a physical fitness score, with one being the lowest and five being the highest fitness level. Then these people were followed for an average of 8 years. During this time, 179 men and 44 women died of cancer.
Data from the Aerobics Center Longitudinal Study show people have lower rates of cancer with higher levels of physical fitness. Studies from the Cooper Institute for Aerobics Research in Dallas suggest that men with high fitness levels are less likely to die of cancer.
The Aerobics Center Longitudinal Study also found that fitness level was more important than weight in predicting longevity (长寿). While results showed that fitness and normal weight are the ideal combination, researchers found that men who were fat but performed well in the machine performance had just a slightly increased all-cause death rate, including cancer, compared to the more slim men. The fat, but fit, men particularly lived longer than the slim, but flabby (肌肉松弛的), men.
These statistics called for a warning to the overweight: The first health goal for the overweight should be to become as fit as possible at their current weight.
67. 1.The text mainly talks about________.
A．the effect of exercise on reducing chances of cancer
B．how to lose weight effectively
C．different ways to keep slim
D．fat men live longer than slim ones
68. 2.What’s Paragraph 2 mainly about?

A 70-year study of personality suggests that pessimism is a risk factor for early death, especially among men.
The study results also indicate that pessimism can be linked to increased risk for sudden death from accidents or violence, according to the report published in the March issue of Psychological Science.
Christopher Peterson of the University of Michigan and his colleagues analyzed data from the Terman Life-Cycle Study, which began by studying California public-school children with high IQs in 1921 and followed them through their life. Most of the 1,528 children were teenagers when the study began. Those still living are now in their 80s. In 1936 and 1940, participants were asked to complete a questionnaire designed to obtain information about difficult life events and their effect on overall outlook. One such question was, “What do you regard as your most serious fault of personality or character?”
Pessimists were defined as fatalistic(宿命论的)people who tend to blame themselves when things go wrong and who believe that one bad event can ruin the rest of their life. They also tend to expect bad things to happen to them and feel that they have little or no ability to change their situation.
Males were more likely than females to be classified as pessimistic. Compared with individuals with a more cheerful and optimistic outlook, pessimists were more likely to die from accidents and violence (including suicide).
A pessimistic personality may lead to poor problem-solving ability, social difficulties and risky decision-making. Taken together, these variables put the pessimist at higher risk of untimely(不适时的) death, say the researchers. Such a person is less likely to avoid or escape potentially dangerous situations, the researchers concluded. “A pessimistic way of thinking in which people worry too much about bad events, predicts untimely death decades later,” according to Peterson.
1.According to the passage, you may be a pessimistic person, if one failure makes you feel________.
A．other people have been unfair to you.
B．other people will help you.
C．you cannot change a bad situation.
D．you can do better next time.
2.According to the passage, pessimists may feel all of the following EXCEPT________
A．helpless when faced with difficulties.
B．cheerful when faced with troubles.
C．hopeless when one bad event occurs.
D．guilty when things go wrong.
3.Which of the following statements is true, according to the passage?
A．Pessimists believe that everything in life depends on fate.
B．There are more pessimists among women than among men.
C．Most pessimists will end up committing suicide.
D．All pessimists will eventually die from accidents.
4.The Terman Life-Cycle Study is a research program that studies________.
A．people over 70 years old.
B．people since their childhood.
C．pessimistic people over 80 years old.
D．only younger people.
5.The analysis made by Christopher Peterson and his colleagues shows that pessimistic people________
A．will die from violence if they learn to be optimistic.
B．will more likely die from violence than optimistic people.
C．will die from violence because their IQs are low.
D．will die untimely if they are not able to learn to be cheerful and optimistic.

Choosing the right university for you is a big decision with many factors to consider. The institution that you choose will not only be the one that ensures your academic goals, but it will also be where you will live, learn, play sports, socialize and work for several years. Therefore, before you start filling out those university application forms, take a step back and consider the many variables that affect the “fit” of a university to your unique personality and educational goals. Take a look at the following factors, and decide which ones mean the most to you.
Consider your educational goals. You will discover that different schools are more recognized or progressive in your chosen field of study than others. For this reason, talk to advisors, professionals in your field, or go to clubs organized by the alumni（校友）. When you check out school ranking for your major, you may find that your first choice is not really a match, while another fits perfectly.
Consider costs. It will be no surprise to you at this point that not all schools cost the same. Some of the more famous schools are so because they are difficult to get into and difficult to pay for. Don’t let this necessarily stop you. Just keep this consideration in mind as you narrow your list of potential schools.
Choosing a university should not be done only on reputation, but also take the academic programs and overall environment into consideration. Be aware that reputations are sometimes out of date or overstated, so first-hand experience is often beneficial.
Once you’ve identified the factors that are most important to you, you’ve taken the first steps towards making a successful choice. Make sure you pick a university that will serve your needs throughout your university career.

Exercise is one of the few factors with a positive role in long-term control of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to "light" beer and low-calorie bread than increase physical efforts. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to lose weight said they were combining exercise with their diet.
In rejecting exercise, some people may be discouraged too much by caloric-expenditure（热量消耗）charts; for example, one would have to quickly walk hard three miles just to work off the 275 calories in one delicious Danish pastry(小甜饼). Even exercise professionals accept half a point here. "Exercise by itself is a very tough way to lose weight," says York Onnen, program director of the President's Council on Physical Fitness and Sports.
Still, exercise's supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight.
If you have been sedentary (极少活动的) and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year's time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight.
1.What is said about the average American in the passage?
A. They tend to hate "light" beer and low-calorie bread.
B. They usually ignore the effect of exercise on losing weight.
C. Most of them were combining exercise with their diet.
D. They know the actors that play a positive role in keeping down body weight.
2."Even exercise professionals accept half a point here" means "They ________".
A. agree that the calories in a small piece of pastry can be easy to work off by exercise
B. partially believe diet plays a supporting role in weight reduction
C. are not fully convinced that dieting can help maintain one's new weight
D. are not sufficiently informed of the positive role of exercise in losing weight
3.What was confirmed by the Boston University Medical Center's study?
A. Controlling one's calorie intake is more important than doing exercise.
B. Even occasional exercise can help reduce weight.
C. Weight reduction is impossible without exercise.
D. One could lose ten pounds in a year's time if there's no increase in food intake.
4.What is the author's purpose in writing this article?
A. To stress the importance of maintaining proper weight.
B. To support the statement made by York Onnen.
C. To show the most effective way to lose weight.
D. To introduce the study of the Boston University Medical Center.

A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increases the risk.
Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma(黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma.
Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence(发生率)faster than any other cancer in the United States.
But questions have been raised about sunscreen and whether it may have the opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.
The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer—people with fair skin and freckles(雀斑), for example—are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.
The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.
1.The underlined word “flaws” in the 2nd paragraph most probably means .
A. evidences B. facts C. faults D. failures
2.People with fair skin and freckles .
A. seldom use sunscreen
B. are more in danger of skin cancer
C. can be free from the harm of the sun
D. often expose themselves to the sun
3.We can learn from the passage that .
A. sunscreen users get skin cancer more often
B. the volunteers have proved the effect of sunscreen
C. the new study was based on the experiences of volunteers
D. the number of skin cancer patients is increasing in America
4.Which of the following can be the best title for this passage?
