题目内容

Exposure to environmental tobacco smoke (ETS)-also called “second-hand smoke” and “passive smoking” contains over 4 000 chemicals, including over 50 known carcinogens (致癌物) and many poisonous things. No safe level of ETS exposure has been proved. Nor is there any expectation that further research will identify such a level.

Several recent reviews have confirmed the serious risks to health and life associated with passive smoking. Long time exposure to second-hand smoke has been proved as a cause of many of the same diseases caused by active smoking, including lung cancer, cardiovascular (心脏血管的) disease, and childhood disease.

Living with a smoker has been shown to increase the risk of coronary heart disease (冠心病) among non-smokers by 25-30% (a recent study indicates that this figure may actually be higher). There is also growing evidence that passive smoking is causally linked to stroke in non-smokers, although further research is needed to estimate the risk.

Second-hand smoke is especially dangerous for young children and infants, being associated with sudden infant death, pneumonia, bronchitis (支气管炎), asthma (哮喘) and respiratory symptoms as well as middle ear disease. ETS exposure in pregnant women can cause lower birth weight, foetal (胎儿的) death and preterm delivery.

Most of the adverse health outcomes brought about by ETS show that the risk increases steadily with increasing exposure. The level of individual risk is lower compared to active smoking. Nevertheless, the fact that large numbers of people are exposed results in a substantial burden of disease.

Action on smoke-free environments would not only protect people from the harm of ETS exposure but also contribute to the reduction of tobacco consumption in the whole population. The health effects of reduced passive and active smoking would include reduced illness and death from major disease types-in particular lung cancer, coronary heart disease, and stroke-and increased life expectancy.

51. Which of the following statements is true? _______

A. Although ETS contains many harmful things, it is not unsafe.

B. The fact that second-hand smoke is safe has been recently found.

C. It is expected that further research will be done to test the level of ETS.

D. By far the safe level of ETS has not been found and will not in the future.

52. Cardiovascular disease can be caused by _______.

A. long time passive smoking B. accidental active smoking

B. occasional passive smoking D. short term active smoking

53. According to the article, the statements about the risk of coronary heart disease are wrong EXCEPT that________

A. if you smoke, the risk of this disease will increase by 25-30%.

B. the non-smokers exposed to smoke will increase the risk of this disease by 25-30%.

C. for the smokers, the risk of getting this disease is higher than that of the non-smokers.

D. the non-smokers exposed to smoke will be more easily to get this disease than the smokers.

54. What does the underlined word “delivery” mean? ________.

A. Transferring to another B. Giving birth C. Throwing away D. Giving out

55. What’s the author’s main purpose in writing this passage? ______

A. To introduce what is ETS.

B. To tell the readers how to avoid ETS.

C. To call for the action against ETS.

D. To warn the readers against smoking.

Marie Curie was a Polish physicist and chemist who lived between 1867-1934. Together with her husband, Pierre, she discovered two new elements (radium and polonium, two radioactive elements that they extracted chemically from pitchblende ore) and studied the x-rays they emitted. She found that the harmful properties of x-rays were able to kill tumors. By the end of World War I, Marie Curie was probably the most famous woman in the world. She had made a conscious decision, however, not to patent methods of processing radium or its medical applications.

Marie Curie was born November 7, 1867 in Poland and died on July 4, 1934. Her co-discovery with her husband Pierre Curie of the radioactive elements radium and polonium(钋) represents one of the best known stories in modern science for which they were recognized in 1901 with the Nobel Prize in Physics. In 1911, Marie Curie was honored with a second Nobel Prize, this time in chemistry, to honor her for successfully isolating pure radium and determining radium's atomic weight.

As a child, Marie Curie amazed people with her great memory. She learned to read when she was only four years old. Her father was a professor of science and the instruments that he kept in a glass case fascinated Marie. She dreamed of becoming a scientist, but that would not be easy. Her family became very poor, and at the age of 18, Marie became a governess. She helped pay for her sister to study in Paris. Later, her sister helped Marie with her education. In 1891, Marie attended the Sorbonne University in Paris where she met and married Pierre Curie, a well-known physicist.

Marie Curie contributed greatly to our understanding of radioactivity and the effects of x-rays. She received two Nobel prizes for her brilliant work, but died of leukemia(白血病), caused by her repeated exposure to radioactive material.

As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through life, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.

Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.

The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities, others lose heart at the first sign of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between "flight or fight" and in more primitive days the choices made the difference between life or death. The crises we meet today are unlikely to be so extreme, but however little the stress, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Since we can't remove stress from our lives (it would be unwise to do so even if we could), we need to find ways to deal with it.

People are finding less and less time for relaxing themselves because _____.

A. they regard working as their greatest enjoyment

B. they believe that work is superior to relaxation

C. they are traveling fast all the time

D. they are becoming busier with their work than ever before

According to the author, the most important character for a good manager is his _____.

A. strong will to hold out stress

B. knowing the art of relaxation

C. high sense of responsibility

D. having control over performance

Which of the following statements is TRUE, according to the passage?

A. We can find quite a few ways to avoid stress.

B. Stress is always harmful to people's health

C. It's easy to change the habit of keeping oneself busy with work.

D. Different people can bear different amount of stress.

In the last sentence of the passage, “do so” refers to _____.

A. "expose ourselves to stress"

B. "find ways to deal with stress"

C. "remove stress from our lives"

D. "establish links between diseases and stress"

According to the author, the right attitude toward stress is _____.

A. to avoid it

B. to try to cope with it

C. to regard it as a vital motivation

D. to find some relaxation

Space is a dangerous place, not only because of meteors (流星 ) but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through, and this is essential for plants to make the food which we eat. Heat, too, makes our environment endurable（可忍受的）. Various kinds of rays come through the air from outer space, but enormous quantities of radiation（辐射） from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage.
Radiation is the greatest known danger to explorers in space. The unit of radiation is called "rem". Scientists have reason to think that a man can put up with far more radiation than 0.1 rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage - a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will no be discovered until the birth of abnormal children or even grandchildren.
Missions of the Apollo flights have had to cross belts of high amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far.

A. it protects him against the harmful rays from space
B. it provides sufficient light for plant growth
C. it supplies the heat necessary for human survival
D. it screens off the falling meteors
2. We know from the passage that ____.
A. exposure to even tiny amounts of radiation is deadly
B. the effect of exposure to radiation is slow in coming
C. radiation is avoidable in space exploration
D. astronauts in spacesuits needn't worry about radiation damage
3. The harm radiation has done to the Apollo crew members ____
A. is significant            B. seems overestimated
C. is enormous             D. remains unknown
4. It can be inferred from the passage that ____.
A. the Apollo mission was very successful
B. protection from space radiation is no easy job
C. astronauts will have deformed children or grandchildren
D. radiation is not a threat to well-protected space explorers
45. The best title for this passage would be ____.
A. The Atmosphere and Our Environment   B. Research on Radiation
C. Effects of Space Radiation             D. Importance of Protection Against Radiation

Warning: reading too much Cinderella to your daughter may damage her emotional health in later life. A paper to be developed at the international congress of cognitive psychotherapy(认知心理疗法) in Gothenburg suggests a link between the attitudes of women abused by their parents and early exposure to the wrong sort of fairy tales. It says girls who identified with Cinderella, Rapunzel and Beauty in Beauty and the Beast were more likely to say in destructive relationships as adults.

The theory was developed by Susan Darker Smith, a psychotherapist at the University of Derby. She interviewed 67 female abuse survivors and found that 61 put up with severe abuse because they believed they could change their partners with patience, composition and love. The same view was taken by male survivors who had been abused as children. Hardly any of the women in a control group, who had not experienced abuse, thought they could change their partners in this way.

The same view was taken by male survivors who had been abused as children. These women and men said they would leave a relationship rather than put up with abuse from a partner. Ms Darker Smith found the abused women were much more likely to identify with Cinderella and other submissive female characters in fairytales, who were later rescued by a stranger prince or hero.

Although most girls heard the stories, damage appeared to be done to those who adopted the characters as role models. “They believe if their love is strong enough they can change their parents’ behaviors,” she said.” Overexposure in children to stories that emphasize the transformational qualities of love may make women believe they can change their partners.” For example, they might never have understood the obvious flaw in the story of Rapunzel, who remained locked in a high tower until rescued by a knight on a white horse, who broke the door down. “The question,” said Ms Darker Smith, “is why she did not break the door down herself.”

B．They don’t believe in the transformational qualities of love.

C．They have also experienced abuse.

D．They survived abuse.

4.What does the underlined word “submissive”in the 3rd paragraph probably mean?

As many as one in five US teenagers have some degree of hearing loss, according to researchers.

They say the problem is growing.

Teenagers really don’t pay attention to how much noise they are exposed (暴露) to, Josef Shargorodsky of Brigham and Women’s Hospital in Boston told Reuters. “Often people won’t notice it, but even slight hearing loss may affect language development,” said Shargorodsky, one of the researchers.

The study compared surveys from the early 1990s and the mid-2000s. Each included a few thousand teenagers. In the first survey, about 15 percent of teenagers had some degree of hearing loss. Some 15 years later, that number had risen by a third, to nearly 20 percent.

“This certainly is big news,” said Alison Grimes, an ear doctor. Hearing loss is very common in old people, Grimes said, but she added that it was worrying to see it happen in the younger age group.

In babies and young children, hearing problems are known to slow language development. The science is less clear for teenagers, but it is easy to imagine how being hard of hearing could affect learning, said Grimes,.

The reasons for the rise are still unclear. When researchers asked teenagers about noise exposure – on the job, at school or from activities, for example – the teenagers didn’t report any change. But Shargorodsky said that might not be true. “We knew from before that it is difficult to ask this age group about noise exposure – they underestimate (低估) it.” Few people would call it noise when they listen to music on their MP3 player, for example. “There is a difference between what we think is loud and what is harmful to the ear,” said Grimes.

Although it’s not clear that the MP3 players cause teenagers’ hearing loss, Grimes said it was still a good idea to turn down the sound and take short breaks from listening.

1.According to the researchers, in a US class of 40 students, about ____ students have some degree of hearing loss.

A. one B. five C. six D. eight

2.Which of the following statements is true according to the article?

A. Slight hearing loss does not influence learning.

B. Only a few old people have hearing problems.

C. Hearing problems can slow language development.

D. Noise exposure is clearly noticed by teenagers.

3.About hearing loss, it can be inferred that ________.

A. the reasons for the rise have been found B. MP3 players are to blame

C. listening to loud music may be a cause D. noise is the main reason

4.The article was written to ______.

A. warn teenagers that loud music might be harmful

B. explain what kinds of noises might affect studies

C. suggest that teenagers shouldn’t listen to loud music

D. show how important hearing can be for learning
