根据材料请回答 16~22

Smoking

Since 1939, numerous studies have been conducted to determine whether smoking is a health hazard.The trend of the evidence has been consistent and indicates that there is a serious health risk.Research teams have conducted studies that show beyond all reasona-ble doubt that tobacco smoking is associated with a shortened life expectancy (预期寿命).

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 throat and is believed to be related to cancer of some other organs of the body.Male cigarette smokers have higher death rate from heart disease than none-smoking males.Female cigarette smokers are thought to be less affected because they do not breathe in the smoke so deeply.

Apart from statistics, it might be helpful to look at what smoking tobacco does to the human body.Smoke is a mixture of gases, vaporized chemicals, minute particles of ash and other solids.There is also nicotine (尼古丁), which is powerful poison, and black tar.As smoke is breathed in, all those components form. deposits on the membranes (膜) of the lungs.One point of concentration is where the air tube and bronchus divides.Most lung cancer begins at this point.

Filters (过滤嘴) and low tar tobacco are claimed to make smoking to some extent sa-fer, but they can only slightly reduce, not eliminate, the hazards.

根据材料请回答 16~22

Plants and Mankind

Botany, the study of plants, occupies a peculiar position in the history of human knowledge. We don't know what our Stone Age ancestors knew about plants, but from what we can observe of pre-industrial societies that still exist, a detailed learning of plants and their properties must be extremely ancient. This is logical. Plants are the basis of the food pyramid for all living things, even for other plants. They have always been enor-mously important to the welfare of people, not only for food, but also for clothing, weap-on, tools, dyes, medicines, shelter, and many other purposes. Tribes living today in the jungle of the Amazon recognize hundreds of plants and know many properties of each. To them botany has no name and is probably not even recognized as a special branch of"knowledge" at all.

Unfortunately, the more industrialized we become the farther away we move from di-rect contact with plants, and the less distinct our knowledge of botany grows. Yet every-one comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose, an apple or an orchid. When our Neolithic ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer yields the next season, the first great step in a new asso-ciation of plants and humans was taken. Grains were discovered and from them flowed the marvel of agriculture: cultivated crops. From then on, humans would increasingly make their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild, and the accumulated knowledge of tens of thousands of years of experience and intimacy with. plants in the wild would begin to fade away.

根据材料请回答 16~22 Disease, Diagnosis Treatment and PreventionDisease may be defined

根据材料请回答 16~22

Disease, Diagnosis Treatment and Prevention

Disease may be defined as the abnormal state in which part or all of the body is not properly adjusted or is not capable of carrying on all its required functions.There are marked (显著的) variations in the extent of the disease and in its effect on the person.

In order to treat a disease, the doctor obviously must first determine the nature of the illness- that is, make a diagnosis.A diagnosis is the conclusion drawn from a number of facts put together.The doctor must know the symptoms(症状), which are the changes in body function felt by the patient; and the signs(体征)(also called objective symptoms)which the doctor himself can observe.Sometimes a characteristic group of signs (or symp-toms) accompanies a given disease.Such a group is called a syndrome(综合症).Frequent- ly certain laboratory tests are performed and the results evaluated by the physicians in making his diagnosis.

Although nurses do not diagnose, they play an extremely valuable role in this process by ob-serving closely for signs, encouraging the patient to talk about himself and his symptoms, and then reporting this information to the doctor.Once the patient's disorder is known, the doctor prescribes a course of treatment, also referred as therapy (疗法).Many measures in this course of treatment are carried out by the nurse under the physician's orders.

In recent years physicians, nurses and other health workers have taken increasing responsi- bilities in prevention.Throughout most of medical history, the physician's aim has been to cure a patient of an existing disease.However, the modem concept of prevention seeks to stop disease before it actually happens to keep people well through the promotion of health.A vast number of organizations exist for this purpose, ranging from the World Health Organization (WHO) on an international level down to local private and community health programs.A rapidly growing re- sponsibility of the nursing treatment profession is educating individual patients toward the mainte- nance of total health physical and mental.

第 16 题 Disease refers to the condition in which one or two parts of the body fail to func- tion properly.

根据下列材料请回答 16~22 题:

Survey Finds Many Women Misinformed about Cancer

Sixty—three percent of American women think that if there’S no family history of cancer,you’re not likely to develop the disease,a new survey found.

In fact,most people who develop cancer have no family history of cancer,according to the American College of Obstetricians and Gynecologists(ACOG)(美国妇产科医师学会),which sponsored the survey.

“Too many women are dying from cancer,”Dr.Douglas W.Laube,ACOG’S immediate past president,said during a Friday teleconference.“An estimated 200,070women will die in the U.S.this year,and over 600,078 women will be diagnosed with cancer,The results of this survey found a worrisome(令人担忧的)gap in women’s know ledge about cancer.”

Based on the findings.ACOG is increasing its efforts to educate women about cancer and the need for regular screening tests.

Although the survey found many misconceptions(错误观念)about cancer,76 percent of women surveyed did say they feel knowledgeable about how they can reduce their risk of the disease.

However,only 52 percent said they were doing enough to reduce that risk.And 10 percent said they hadn’t done anything in the past year to lower their risk.Seventeen percent said they wouldn’t change their lifestyles,even if changes would lower their cancer risk.

Many women said they were afraid to undergo screening out of fear of finding cancer。Twenty percent said they didn’t want to know if they had cancer.

In response to these findings.ACOG will launch on Oct.29 a new website—Protect&Detect:What Women Should Know about Cancer.The guide is designed to help women to take charge of their health and improve their understanding of their risk of cancer—and the lifestyle. steps they can take to cut that risk.

根据下列材料请回答 16~22 题:What Is Giobalization ?It was the anti—globalization movement

根据下列材料请回答 16~22 题:

What Is Giobalization ?

It was the anti—globalization movement that really put globalization on the map.As a word it has existed since the 1 960s,but the protests against this allegedly new process,which its opponents condemn as a way of ordering people’S lives,brought globalization out of the financial and academic worlds and into everyday current affairs.

In the late 1 980s and early 1 990s.the business model called the“globalized”financial market came to be seen as an entity that could have more than just an economic impact on the parts of the world it touched.Globalization came to be seen as more than simply a way of doing business,or running financial markets—it became a process.From then on the word took on a life of its own.

So how does the globalized market work? It is modern communications that make it possible;for the British service sector to deal with its customers through a call centre in India,or for a sportswear(运动服)manufacturer to design its products in Europe,make them in south.east Asia and sell them in north America.

But this is where the anti—globalization side gets stuck in(关注).If these practices replace domestic economic life with an economy that is heavily influenced or controlled from overseas.then the creation of a globalized economic model and the process of globalization can also be seen as a surrender of power to the corporations,or a means of keeping poorer nations in their place。

Not everyone agrees that globalization is necessarily evil,or that globalized corporations are running the lives of individuals or are more powerful than nations.Some say that the spread of globalization,free markets and free trade into the developing world is the best way to beat poverty—the only problem is that free markets and free trade do not yet truly exist.

Globalization can be seen as a positive,negative or even marginal process.And regardless of whether it works for good or ill,globalization’S exact meaning will continue to be the subject of debate among those who oppose,support or simply observe it.

第 16 题 Globalization is a term used only in the financial and academic worlds.

A.Right

B.Wrong

根据材料请回答 16~22 American SportsThe United States is a sports-loving nation. Sport

根据材料请回答 16~22

American Sports

The United States is a sports-loving nation. Sports in America take a variety of forms: organized competitive struggles, which draw huge crowds to cheer their favorite team to victory; athletic games, played for recreation anywhere sufficient space is found; and hunting and fishing.Most sports are seasonal, so that what is happening in sports de-pends upon the time of year.Some sports are called spectator sports, as the number of spectators greatly exceeds the number playing in the game.

Baseball is the most popular sport in the US.It is played throughout the spring and summer, and professional baseball teams play well into the fall.Although no other game is exactly like baseball, perhaps the one most nearly like it is the English game of cricket.

Football is the most popular sport in the fall.The game originated as a college sport more than 75 years ago.It is still played by almost every college and university in the country, and the football stadiums of some of the largest universities seat as many as 80,000 people.The game is not the same as European football or soccer.In American football there are 11 players on each team, and they are dressed in padded uniforms and helmets because the game is rough and injuries are likely to occur.

Basketball is the winter sport in American schools and colleges.Like football, bas-ketball originated in the US and is not popular in other countries.Many Americans prefer it to football because it is played indoors throughout the winter and because it is a faster game.It is a very popular game with high schools, and in more than 20 states, state-wide high school matches are held yearly.

Other spectator sports include wrestling, boxing, and horse racing.Although horse-racing fans call themselves sportsmen, the accuracy of term is questionable, as only the jockeys who ride the horses in the races can be considered athletes.The so-called sports-men are the spectators, who do not "assemble" primarily to see the horse race, but to bet upon the outcome of each race.Gambling is the attraction of horse racing.

第 16 题 Hunting and fishing are mainly favored by men, young and old in the US.

A.Right

B.Wrong
