Prolonging Human Life
Prolonging human life has increased the size of the human population.Many people alive to-day 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 contempo- rary 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.
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.

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：

第一段最后一句说“In fact , it is a decrease in death rates , not an increase in birthrates , that has led to the population explosion.”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，选项C是正确答案。

第二段第四句说“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 an-other child.”在灾年，可能会容忍婴儿死亡，因为，如果他们的父母俄死了，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，选项B是正确的答案。

第二段倒数第二句是这么说的“In the United States many retired people live on social security checks which are so little that they must live in near poverty."（在美国，许多退休人员依靠社会保障金生活，其数额之小差不多使人穷困潦倒。）可以看出，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，因而选项A是正确的答案。

第三段第三句“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."（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虚弱的人。) " this need”出现在下面这个短语中："To meet this need "（为了满足这种需要），它指句子前面的“care for a sick or weak person"。这正是选项D表达的意思。

文章的最后一句说“... most of them are simply " dumping grounds" for the dying in which "care" is given by poorly paid overworKea , and under-skilled personnel"（大多数机构只不过是倾倒垂死的人的“垃圾场”，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。）作者如此措辞显然是对大多数机构的强烈批评。因此，选项 D是正确答案。

第13题：

40 years ago the idea of disabled people doing sport was never heard of. But when the annual games for the disabled were started at Stoke Mandeville, England in 1948 by Sir Ludwig Guttmann, the situation began to change.
Sir Ludwig Guttmann, who had been driven to England in 1939 from Nazi Germany, had
been asked by the British government to set up an injuries center at Stoke Mandeville Hospital near London. His ideas about treating injuries included sport for the disabled.
In the first games just two teams of injured soldiers took part. The next year, 1949, five teams took part. From those beginnings, things have developed fast. Teams now come from abroad to Stoke Mandeville every year. In 1960 the first Olympics for the Disabled were held in Rome, in the same place as the normal Olympic Games. Now, every four years the Olympic Games for the Disabled are held, if possible, in the same place as the normal Olympic Games, although they are organized separately. In other years Games for the Disabled are still held at Stoke Mandeville. In the 1984 wheelchair Olympic Games, 1064 wheelchair athletes from about 40 countries took part.
Unfortunately, they were held at Stoke Mandeville and not in Los Angeles, along with the other Olympics.
TheGameshavebeenagreatsuccessinpromotinginternationalfriendshipandunderstanding, and in proving that being disabled does not mean you can't enjoy sport. One small source of disappointment for those who organize and take part in the games, however, has been the unwillingness of the International Olympic Committee to include disabled events at Olympic Games for the able-bodied. Perhaps a few more years are still needed to convince those fortunate enough not to be disabled that their disabled fellow athletes should not be excluded.
In Paragraph 3, the underlined word "athletes" means__________.

A.people who support the games
B.people who watch the games
C.people who organize the games
D.people who compete in the games

答案：D

解析：

由第三段“In the l984 wheelchair Olympic Games，1064 wheelchair athletes from about 40countries took part．"可知，参加轮椅残奥会的athletes应是指运动员，故选D。

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.

The writer believes that the population explosion results from______.
A: an increase in birthrates
B: the industrial development
C: a decrease in death rates
D: cultural advances

答案：C

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”。

The writer believes that the population explosion results from______.
A:an increase in birthrates
B:the industrial development
C:a decrease in death rates
D:cultural advances

答案：C

解析：

由文章第一段最后一句可知，导致人口爆炸的原因事实上是死亡率的降低，而不是出生率的增高，故选C。
由文章第二段第四句可知，在狩猎与采集时代，遇到饥荒时，幼儿的死亡是可以接受的，因为如果其父母被饿死，幼儿也无法存活下去。B选项符合文意。
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。
此句话之前的内容为：如今，大部分的家庭成员都去工作或上学，经常会发生无人在家照看生病体弱者的情况。接着本句话指出：为了满足这种需求……由此可知，这种需求指对照顾生病体弱者的需求。故本题选D。
由文章的最后一句可知，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，故选D。

A.was lying，had laid，laid，lay
B.had laid，lay，laid，was lying
C.lay，was lying，lain， lay
D.laid，lay，lain，lies

答案：A

解析：

题目意为“当那男孩说在他躺下来休息之前把母鸡下的蛋放到柜子里去了时，他在撒谎。”lie意为“说谎，躺”,过去式为lied，过去分词为lied，现在分词为lying；lay意为“放,下蛋”，为及物动词，过去式为laid，过去分词为laid，现在分词为laying。其中，lie down为固定搭配，意为“躺下”，根据题干中“said”确定要选择过去时态，为lay down，可以排除选项B和D，且before引导的句子中，主句用过去完成时,从句用一般现在时，因此he（）the eggs应当是过去完成时态，为had laid，故选项A正确。

Practice 1　　Between persons of equal income there is no social distinction except the distinction of merit. There in the world would be great people and ordinary people and little people, but the great would always be those who had done great things, and never the fools whose mothers had spoiled them and whose fathers had left them a hundred thousand a year, and the little would be persons of small minds and mean characters, and not poor persons who had never had a chance. That is why fools are always in favor of inequality of income (their only chance of eminence), and the really great in favor of equality.

在收入相等的人之间,根本不存在社会差别,只有功绩上的差别。世界上存在着伟大的人、普通的人和渺小的人,不过伟人总是那些做出大事的人,而不是那些受到母亲宠爱,父亲每年留给他们十万元的白痴;渺小的人则是那些心胸狭隘、品质卑鄙的人,而不是那些从来没有机会的穷人。白痴总是主张收入不均(这是他们出人头地唯一的机会),真正的伟人则主张平等,原因即在于此。

问答题

Practice 3　　Science, in practice, depends far less on the experiments it prepares than on the preparedness of the minds of the men who watch the experiments. Sir Isaac Newton supposedly discovered gravity through the fall of an apple. Apples had been falling in many places for centuries and thousands of people had seen them fall. But Newton for years had been curious about the cause of the orbital motion of the moon and planets. What kept them in place? Why didn’t they fall out of the sky? The fact that the apple fell down toward the earth and not up into the tree answered the question he had been asking himself about those larger fruits of the heavens, the moon and the planets.

正确答案：
【参考译文】
在实践中,科学与其说依靠事先准备的实验,不如说依靠实验观察者有所准备的头脑。艾萨克·牛顿爵士通过对苹果落地进行推理发现了重力。多少世纪以来,苹果一直在许多地方落到地面,成千上万个人看到苹果落地。而牛顿多年来一直对月球和行星绕轨道运行的起因感到好奇。是什么力量使得它们处于现在的位置呢?它们为什么不落到天空之外呢?苹果向下落到地上而不是向上飞到树上这一事实回答了牛顿长期以来对月球和行星所存有的疑问。月球和行星是苍天中更大的果实。
