Dental Health　　Decay is not the only disease that can cause

题目
问答题
Dental Health　　Decay is not the only disease that can cause tooth loss. Another serious disease affects the gums, the tissue that surrounds the teeth. It is also caused by bacteria. If the bacteria are not removed every day, they form a substance that stays on the teeth. The substance is known as plaque. At first, the gums appear to be swollen, and may bleed when the teeth are brushed. This can lead to serious infection of the tissue around the teeth. The infection may damage the bone that supports the teeth and cause tooth loss and other health problems. Studies have found that people with severe gum disease have an increased risk of developing heart disease, diabetes and stroke.　　Gum disease can be treated by a special dentist called a periodontist. Periodontists are trained to repair the gum areas that have been damaged. This can be painful and costly.　　Dental health experts say the best thing to do is to stop gum disease before it starts. The way to do this is to clean the teeth every day. People also should use dental floss to remove plaque from between the teeth. Most experts also agree that another way to prevent tooth and gum problems is to eat foods high in calcium and vitamins and low in sugar.　　Scientists continue to develop better dental treatments and equipment. Improved technology may change the way people receive dental treatment in the future. For example, dentists are now suing laser light to treat diseased gums and teeth. Dentists use computer technology to help them repair damaged teeth. Researchers have developed improved methods to repair bone that supports the teeth. And genetic research is expected to develop tests that will show the presence of disease causing bacteria in the mouth.　　Such increased knowledge about dental diseases and ways to prevent them has improved the health of many people. Yet problems remain in some areas. In industrial countries, minorities and other groups have a high level of untreated dental disease. In developing countries, many areas do not have even emergency care services. The World Health Organization says people in countries in Africa have the most tooth and gum problems.　　World Health Organization experts say the dental health situation is different for almost every country in the world. As a result, it has developed oral health programs separately for each area.　　The WHO oral health program is mainly for people living in poor areas. It provides them with information about mouth diseases and health care. It also studies preventive programs using fluoride in water, salt, mild and toothpaste. And it explores ways to include dental health in national health care systems.　　Many governments and other organizations provide help, so people can get needed dental health services. But dental health professionals say people should take good care of their teeth and gums.　　They say people should keep their teeth as clean as possible. They should eat foods high in calcium and fiber. These include milk products, whole grain breads and cereals, vegetables, fruits, beans and nuts. Recent studies have shown that eating nuts can help slow the production of plaque on the teeth.　　Experts say these activities will help everyone improve their dental health throughout their lives.
参考答案和解析
正确答案： 【参考译文】
牙齿保健 龋齿并不是唯一一种能对牙齿造成伤害的疾病,还有一种疾病严重影响了牙齿周围的牙龈,它也是由于口腔细菌造成的。如果你不每天清除口腔内的细菌,它们就会在你的牙齿上形成一种叫做牙斑的物质。
起初,牙龈表现为肿胀,刷牙的时候会出血,并会导致牙周组织的严重感染。这种感染可能会伤及支撑牙齿的骨骼,然后造成牙齿脱落或产生其他健康问题。研究表明,严重牙周疾病患者比一般人更容易得心脏病、糖尿病和中风。
牙周病可由专门的牙周病医师来进行治疗。他们一般都接受过正规培训,能够修复牙龈周围受到破坏的部分。但是这一过程比较痛苦而且价格昂贵。牙齿保健专家认为,最好的办法就是提前杜绝牙周炎的发生,方法是每天清洁牙齿。人们可以使用牙线来清除牙齿间的牙斑。多数专家认为,我们还可以通过摄入富含钙及维生素,或是含糖量少的食物以防止牙齿及牙龈疾病的发生。
科学家们正在继续研发更好的牙齿保健及医疗工具。改进后的技术将来可能会改变人们接受牙科治疗的方法。例如,牙医们目前使用激光来治疗损坏的牙龈和牙齿,他们还使用了计算机技术帮助修复损坏的牙齿。研究人员已经找出了修复支撑牙齿的骨骼的方法。一项遗传研究即将展开,它将会证明口腔内存在造成口腔疾病的细菌。
不断增长的牙科疾病知识和预防方法改善了许多人的身体状况,但是在某些地方还存在一些问题。在工业化国家,许多少数民族和其他社会群体中存在数量较多的没有得到治疗的牙科疾病。在发展中国家,许多地区甚至没有紧急医疗中心。世界卫生组织声称,非洲人在牙齿和牙周方面存在更多的问题。
世界卫生组织的专家说,几乎每个国家的牙齿健康状况都不相同,其结果就是每个地方都有各自的口腔保健计划。
世界卫生组织的口腔保健计划主要是针对那些住在贫困地区的人们。该计划为人们提供有关口腔疾病和保健方面的信息,也研究出了多种预防方法,如在水、盐、牛奶和牙膏中添加氟化物。同时,它也探索了把牙齿健康纳入国家健康保健系统的方法。
在许多政府和其他组织提供的帮助下,人们能够得到所需的牙齿健康服务。但是牙齿健康专家表示,人们应该好好照顾自己的牙齿和牙龈。
他们说,人们应当尽量保持牙齿的清洁,并且应该多吃含钙和纤维丰富的食物。包括奶制品、全麦面包及谷类食物、蔬菜、水果、大豆和坚果。近期研究表明,食用坚果能够缓解牙斑的形成。
专家们认为,这些做法将帮助人们改善牙齿状况,使他们终身受益。

Passage Two

Questions 26 to 30 are based on the following passage.

Scientists have established that influenza viruses taken from man can cause the disease in animals. In addition，man can catch the disease from animals. In fact，a great number of wild birds seem to carry the virus without showing any evidence of illness. Some scientists conclude that a large family of influenza viruses may have evolved in the bird kingdom，a group that has been on the earth 100 million years and is able to carry the virus without contracting the disease. These are even convincing evidence to show that virus strains are transmitted from place to place and from continent to continent by migrating birds.

It is known that two influenza viruses can recombine when both are present in an animal at the same time. The result of such recombinations is a great variety of strains constraining different H and N spikes. This raises the possibility that a human influenza virus can recombine with an influenza virus form. a lower animal to produce an entirely new spike.

Research is underway to determine if that is the way that major new strains come into being. Another possibility is that two animal influenza strains may recombine in a pig，for example，to produce a new strain which is transmitted to man.

According to the passage，scientists have discovered that influenza viruses______.

A. cause ill health in wild birds

B. do not always cause symptoms in birds

C. are rarely present in wild birds

D. change when transferred from animals to man

U. S. States Do Poorly in Women's Health

Not a single U. S. state meets basic federal goals for women's health,and the nation
as a whole fails except in two areas一mammograms（乳腺X光照片）and dental（牙齿的）
check-ups一researchers said on Thursday.
Millions of women lack health insurance,and states make it difficult to enroll（加入）in
Medicaid,the state-federal health insurance plan for the poor,according to the report.
And few states are doing anywhere near enough to help women quit smoking一the
leading cause of death in the United States.
"The nation as a whole and the individual states fall short of meeting national goals,"
reads the report,put together by the National Women's Law Center and the Oregon
Health&Science University."These health goals provide a road map for assessing the
status of women's health."
Of 27 measures examined by the group,from screening for diseases to actually treating
them,the nation passes on only two,the researchers said."The nation is so far from the
health goals that it receives an overall grade of'unsatisfactory',"they wrote.
The problem seems to be a lack among states of an overall plan for health in general,
the NWLC said.
" State policy makers' piecemeal（一件一件做的）approach to our health care crisis has
resulted in a complex and ineffective system that fails to meet the health care needs of
women,"Judy Waxman,NWLC Vice President for Health,said in a statement.
"Lawmakers need to take a comprehensive,long-term approach to meeting women's
health needs and tackle this serious problem that troubles so many families."

In which area is the nation successful?
A:Dental check-ups.
B:Health promotion.
C:Disease screening.
D:Cancer treatment.

As we have seen,the focus of medical care in our society has been shifting from curing disease to preventing disease一especially in terms of changing our many unhealthy behaviors,such as poor eating habits,smoking,and failure to exercise.The line of thought involved in this shift can be pursued further. Imagine a person who is about the right weight , but does not eat very nutritious（有营养的）foods , who feels OK but exercises only occasionally , who goes to work every day , but is not an outstanding worker,who drinks a few beers at home most nights but does not drive while drunk, and who has no chest pains or abnormal blood counts,but sleeps a lot and often feels tired.This person is not ill.He may not even be at risk for any particular disease.But we can imagine that this person could be a lot healthier.
The field of medicine has not traditionally distinguished between someone who is merely "not ill" and someone who is in excellent health and pays attention to the body's special needs.Both types have simply been called "well".In recent years,however,some health specialists have begun to apply the terms "well" and "weilness" only to those who are actively striving to maintain and improve their body's condition.Most importantly,perhaps,people who are well take active responsibility for all matters related to their health.Even people who have a physical disease or handicap（缺陷）may be "well" ,in this new sense,if they make an effort to maintain the best possible health they can in the face of their physical limitations."Wellness" may perhaps best be viewed not as a state that people can achieve,but as an ideal that people can strive for. People who are well are likely to be better able to resist disease and to fight disease when it strikes.And by focusing attention on healthy ways of living,the concept of weilness can have a beneficial impact on the way in which people face the challenges of daily life.

The first paragraph implies that_________.
A:good health is more than not being ill
B:sleeping a lot could be harmful
C:regular health checks are essential to keeping fit
D:prevention is more difficult than care

答案：A
解析：
细节题。根据第一段第一句“…the focus of medical care in our society has been-shifting from curing disease to preventing disease一especially in terms of changing our many unhealthy behaviors...”可知，今天医疗保健的焦点已经从疾病治疗转移到疾病预防上来，尤其体现在改变我们不健康的行为上。因此，选项C“改变人们不良的生活习惯”与文章相符。
主旨题。由第一段倒数三句“This person is not ill.He may not even be at risk for any particular disease.But we can imagine that this person could be a lot healthier.”可知，这个人虽然有一些不良习惯和不适的症状，但是没有患病，甚至也没有患病的风险，然而，我们可以想象这个人本来可以更健康。由此可知，选项A“健康不仅仅是没有病”符合文意。
推断题。根据第二段第一、二句“The field of medicine has not traditionally distinguished between someone who is merely'not ill'and someone who is in excellent health and pays attention to the body's special needs.Both types have simply been called 'well'.”可知，传统上，医学界把没病的人和十分健康的人都称作“身体良好的人”。因此，选项D“没病就是身体良好”符合文意。
细节题。根据第二段的倒数第三句“'Weilness' may perhaps best be viewed not as a state that people can achieve,but as an ideal than people can strive for.”可知，“健康”并不是我们可能获得的一种健康的状态，而是一种我们要努力争取的理念。因此选项B 符合题意。
主旨题。文章第一段提出医疗保健的焦点由疾病治疗转到疾病预防；第二段首先阐述了传统医疗保健观点和现在医疗保健观点对健康的定义，之后依据现在医疗保健观点给健康作出了更积极的定义，可见选项C符合题意。选项A"旨在批判医疗保健的传统观点”是对原文的曲解，原文只是提出新的观点，并没有批驳传统的医疗保健；选项B"旨在对比传统和现在医疗保健观、点的不同”不是本文的写作目的，比较的目的在于强调现在的医疗观；选项D"旨在告诉我们医疗保健的重要性”文中并未提及。
