Head injuries are often fatal, or of sufficient severity to require the hospitalization of victims. But there is a large group of people who sustain head injuries which can go undetected through ordinary medical examination. These are the people who seemingly recover from their injuries but still suffer subtle intellectual and behavioural effects that may seriously impair their ability to work and interact normally with other people. They are the victims of what experts call a “silent epidemic”. Some never lost consciousness and others never even suffered a direct blow to the head, yet brain damage occurred.

正确答案：
头部受伤往往会造成死亡或者重伤,需要让病人住院治疗。但是有许多人虽然头部受伤,医院的常规检查却发现不了。这些人受伤以后似乎得到了恢复,但是他们在智力或行为方面仍然有不易察觉的后遗症,这会严重影响他们的工作能力和与他人进行正常交往的能力。专家管这种人患的病叫做“不声不响的流行病”。有的人根本没有失去知觉,有的人甚至头部根本没有受到直接的撞击,然而脑子却受了伤。

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。 -

Prolonging Human Life
1.Prolonging human life has increased the size of the human population.Many people alive today would have died of childhood diseases if they had been born 100 years ago.Because more people live longer,there are more people around at any given time.In fact,it is a decrease in death rates,not an increase in birthrates,that has led to the population explosion.
2.Prolonging human life has also increased the dependency load.In all societies,people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures,old people who could not keep up might be left behind to die.In times of famine,infants might be allowed to die because they could not survive if their parents starved,whereas if the parents survived they could have another child.
3.In most contemporary societies,people feel a moral obligation to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work.We also have rules which require people to retire at a certain age.Unless these people were able to save money for their retirement,somebody else must support them.In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illness than young or middle-aged people.Unless they have wealth or private or government insurance,they must often"go on welfare"if they have a serious illness.
4.When older people become senile or too weak and ill to care for themselves,they create grave problems for their families.In the past and in some traditional cultures,they would be cared for at home until they died.Today,with most members of a household working or in school,there is often no one at home who can care for a sick or weak person.To meet this need,a great many nursing homes and convalescent hospitals have been built. These are often profit-making organizations, although some are sponsored by religious and other nonprofit groups.While a few of these institutions are good,most of them are simply"dumping grounds"for the dying in which"care"is given by poorly paid,overworked,and under-skilled personnel.Many people would have died of_______if they had been born 100 years ago.
A:too weak and ill
B:hunting and gathering cultures
C:childhood diseases
D:no one at home
E:epidemic diseases
F: traditional cultures答案：C解析：文章第一段提出了延长寿命会造成地球人口数量增加的观点，并解释了导致这一现象的原因。因此答案应当选择选项B。
文章第二段主要讲的是延长人寿命的同时也使要照顾的人数增加了。因此选择D项。
文章第三段主要解释为什么说老年人会是社会沉重的负担。因此选择A项。
第四段主要讲的是当今社会老年人生活的状况，及他们生病或身体变弱后会受到的照顾。因此选择F项。
文章第一段提到如果出生在100年前，很多人会早早死于儿童疾病。因此选项C是正确的。
文章第二段讲到在过去的狩猎和采集文化时代，部落里跟不上队伍的老年人会被撤下任其死去。因此选项B是正确的。
第四段第一句讲到，在如今的社会老人生病或变得虚弱会给家庭带来很大的负担。因此选项A是正确的。
文章最后一段描述现代社会的人们工作和生活的压力很大，大部分情况下没有人能留在家里照顾老人，因此选项D是正确的。 -

第9题：
问答题Read the passage carefully and answer Questions 1 to 5. Answer each question in a maximum of 10 words. Remember to write the answers on the Answer Sheet. In the United States today, many people want a college education. However, almost half of the people who go to college now do not attend a four-year college. Instead, they go to a community college. The community college offers a two-year course of study in a wide range of subjects. It prepares some young people to go on to a four-year college. It trains others for jobs in business, government, or industry. Some people choose a community college because of cost. The tuition for a semester at a community college can be less than half the cost of a semester at a four-year college. Also, since these colleges are located in large communities, their students can save money by living at home. Community colleges are also useful for people who have jobs and who do not have time for a traditional four-year college. Some of these people take night courses at community colleges. Others complete long-distance courses, in which they stay at home and use video-tapes, audiotapes, and the Internet. Community colleges also serve high school graduates who only achieved low grades. Many of these students would not be admitted to a four-year college. If they do well, they may go on to a four-year college. Today, the country’s 1,500 community colleges have more than 10 million students. These colleges are making it possible for more and more people to continue their education. Questions: 1．What is the passage mainly about? 2．What does theyin paragraph 1 refer to? 3．In which fields does a community college provide job training? 4．Why do people often prefer to go to a community college? 5．What does the word tuitionin paragraph 3 mean?正确答案：
1.(the advantages of)community college 本文主要介绍了与普通高校相比,社区学院的各项优点,如:开设课程广泛、学费低以及适合各类学生进修等。
2.half of the people who go to college now ”instead”表意思转折,前后共享一个主语。
3.business, government, or industry 第二段最后一句提到社区学院在商务,政府和工业领域为学生提供职能培训。
4.low cost 第三段提到许多人出于费用考虑选择社区学院,因为它的学费低于四年制高校的一半,并且因为离家近很多学生可以直接住在家里从而节省住宿费。这是community college区别于其他院校最大的地方。

单选题Although many people would not believe it, the mosquito is actually the most dangerous animal in Africa. While the bite of the black mamba is invariably lethal when untreated, this dreaded snake kills only a few dozen people per year. Hippopotami, with their immense strength and foul dispositions, kill hundreds of people per year in rivers and lakes, but the mosquito is still more dangerous. Mosquitoes bite hundreds of millions of people in Africa every year, and they infect over a million each year with malaria, a disease that is often fatal. Which of the following questions would be most useful in evaluating the claim made above regarding the mosquito?ACould a person survive an attack by a black mamba if that person received prompt medical attention?
BWhat criteria are used to determine which animal is the “most dangerous” animal?
CCould the incidence of mosquito bites be decreased through the judicious use of pesticides and insect repellent?
DDoes malaria kill more people per year in Africa than tuberculosis?
EHow does the percentage of people who survive hippopotamus attacks in Africa each year compare with the percentage of people who survive mosquito bites?
正确答案： C解析：
文段中对于非洲蚊子的结论是：“the mosquito is actually the most dangerous animal in Africa.”，之后作者比较了蚊子和其他生物的致死率的数据，故B问题能更好的帮助我们估计这一结论，故本题选B。 -

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.We can learn from the passage that today medical care focuses on__________.
A:curing disease and keeping people in healthy physical conditions
B:monitoring patients' body functions
C:removing peoples' bad living habits
D:ensuring peoples' psychological well-being答案：C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。 -

Prolonging Human Life
1.Prolonging human life has increased the size of the human population.Many people alive today would have died of childhood diseases if they had been born 100 years ago.Because more people live longer,there are more people around at any given time.In fact,it is a decrease in death rates,not an increase in birthrates,that has led to the population explosion.
2.Prolonging human life has also increased the dependency load.In all societies,people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures,old people who could not keep up might be left behind to die.In times of famine,infants might be allowed to die because they could not survive if their parents starved,whereas if the parents survived they could have another child.
3.In most contemporary societies,people feel a moral obligation to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work.We also have rules which require people to retire at a certain age.Unless these people were able to save money for their retirement,somebody else must support them.In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illness than young or middle-aged people.Unless they have wealth or private or government insurance,they must often"go on welfare"if they have a serious illness.
4.When older people become senile or too weak and ill to care for themselves,they create grave problems for their families.In the past and in some traditional cultures,they would be cared for at home until they died.Today,with most members of a household working or in school,there is often no one at home who can care for a sick or weak person.To meet this need,a great many nursing homes and convalescent hospitals have been built. These are often profit-making organizations, although some are sponsored by religious and other nonprofit groups.While a few of these institutions are good,most of them are simply"dumping grounds"for the dying in which"care"is given by poorly paid,overworked,and under-skilled personnel.In________,old people who could not keep up might be abandoned to die.
A:too weak and ill
B:hunting and gathering cultures
C:childhood diseases
D:no one at home
E:epidemic diseases
F: traditional cultures答案：B解析：文章第一段提出了延长寿命会造成地球人口数量增加的观点，并解释了导致这一现象的原因。因此答案应当选择选项B。

Prolonging Human Life
Prolonging human life has increased the size of the human population. Many people alive
today would have died of childhood diseases if they had been born 100 years ago.Because
more people live longer,there are more people around at any given time. In fact,it is a decrease in death rates,not an increase in birthrates,that has led to the population explosion.
Prolonging human life has also increased the dependency load. In all societies,people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures,old people who could not keep up might be left behind to die. In times of famine,infants might be allowed to die because they could not survive if their parents starved,whereas if the parents survived they could have another child. In most contemporary societies,people feel a moral obligation to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work;we also have rules which require people to retire at a certain age. Unless these people were able to save money for their retirement,some-body else must support them. In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illness than young or middle-aged people;unless they have wealth or private or government insur-ance,they must often“go on welfare” if they have a serious illness.
When older people become senile or too weak and ill to care for themselves,they create grave problems for their families. In the past and in some traditional cultures,they would be cared for at home until they died. Today,with most members of a household working or in school,there is often no one at home who can care for a sick or weak person. To meet this need,a great many nursing homes and convalescent hospitals have been built.These are of-ten profit-making organizations,although some are sponsored by religious and other nonprofit groups.While a few of these institutions are good,most of them are simply“dumping grounds”for the dying in which“care”is given by poorly paid,overworked,and under-skilled personnel.It can be inferred from the passage that in hunting and gathering cultures______.
A: it was a moral responsibility to keep old-aged people alive
B: infants could be left dead in times of starvation
C: parents had to impart the cultural wisdom of the tribe to their children
D: death was considered to be freedom from hardships答案：B解析：题干意为“作者认为造成人口爆炸的原因是什么？”利用题干中的细节信息短语population explosion作为定位线索，在第一段中找到相关句：In fact, it is a decrease in death rates, not an increase in birthrates, that has led to the population explosion．该句意为 “事实上，是由于死亡率的下降，而不是出生率的上升，导致了人口爆炸”。因此，C项“死亡率的下降”是正确答案。
题干意为“从短文中可以推断出狩猎和以采集为生的时代……”。利用题干中的细节信息词/短语hunting和gathering cultures作为定位线索，在第二段中找到相关句： In hunting and gathering cultures,old people who could not keep up might be left behind to die. In times of famine,infants might be allowed to die because they could not survive if their parents starved, whereas if the parents survived they could have another child．相关句意为 “在以狩猎和采集为生的时代，不能跟上其他人的老人会被甩在后面，任他死去。在饥荒时，人们会放任婴儿死亡，因为如果他们的父母饿死了，他们也无法生存，而如果父母生存下来可重新生儿育女”。因此，B项“遇到饥荒时，人们会放任婴儿死亡”是正确的答案。
题干意为“依据短文内容来看，关于美国退休人员的陈述下面哪个选项正确？”利用题干中的细节信息短语retired people和the United States作为定位线索，在第二 段中找到相关句：In the United States many retired people live on social security checks which are so little that they must live in near poverty．该句提到“在美国，许多退休人员依靠社会保障金生活，其数额非常微薄，使得他们几乎挣扎于贫困的边缘”，由此可知在美国许多退休人员的生活是很艰难的。这正是选项A表达的意思，因而A项“许多人生活艰难”是正确的答案。
题干意为“在第三段中，‘this need’…”。该题属于词汇题中的语篇衔接词 题。首先找到“this need”所在的句子：To meet this need, a great many nursing homes and convalescent hospitals have been built. “this need”应该回指上文中具体提到的需要，因此关 注上文，首先关注该句的前一句：Today, with most members of a household working or in school, there is often no one at home who can care for a sick or weak person．该句意为“当今，由于家庭中大多数人都出去工作或上学，家里常常没有人来照顾有病或身体虚弱的人”。由此可知上文中提到的需要是“照顾有病的和身体虚弱的人”，因此答案为D项“需要照顾有病的和身体虚弱的人”。
题干意为“下面哪个选项能最恰当地描述作者对养老院和康复医院的态度？”该题属于主旨题，通常短文主题会在短文开头及/或短文结尾处有明确体现，因此首先关 注短文结尾处的句子：...most of them are simply “dumping grounds” for the dying in which“care” is given by poorly paid, overworked, and under-skilled personnel．该句提到“大多数机构只不过是丢弃垂死的人的‘垃饭场’，所谓的‘照顾’都是由收入低、超量工作、技术水平低下的人员提供的”。从作者的用词中可以看出作者在对包括养老院和康复医院的大多数机构持批评的态度，因此答案为D项“批评性的”。 -

由文章第二段倒数第二句可知，在美国，很多退休后的人靠社会救济金生活，而救济金的数额非常小，以至于他们的生活穷困潦倒。A项的含义为他们大部分人过着艰难的生活，符合文意。

由文章最后一段的最后一句可知，这些护理机构中只有极少数是不错的，绝大多数就如同接收濒临死亡者的“垃圾场”一样，所提供的“照顾”也都是由收人低、过度劳累及技术水平低下的人完成的，故本题选D。 -

问答题Practice 6 With a high degree of specialization, the frontiers of knowledge are steadily being pushed back more rapidly than ever before. But this has not been achieved without considerable cost. The scientist, who outside his own particular subject is little more than an idiot, is a modern phenomenon; as is the man of letters who is barely aware of the tremendous strides that have been made in technology. Similarly, specialization has indirectly affected quite ordinary people in every walk of life. Many activities which were once pursued for their own sakes are often given up in despair: they require techniques, the experts tell us, which take a life-time to master. Why learn to play the piano, when you can listen to the world’s greatest pianists in your own drawing-room?正确答案： 【参考译文】
随着知识的高度专业化,各学科正以前所未有的速度不断发展,但为此也付出了高昂的代价。一个科学家一旦脱离了其自身研究领域,即与白痴无异,这不能不说是现代社会的咄咄怪事。而对于科技方面的重大进展,文人也同样几乎一无所知。同样,专业化也使各行各业的普通人受到间接的影响。人们以往的那些兴趣爱好,现在却不得不绝望地放弃,因为专家告诉我们,兴趣需要技术,且穷尽一生才能掌握。当你能在自己的客厅欣赏到世界上最伟大的钢琴家演奏时,你还学习钢琴干什么呢? 解析： 暂无解析 -
