Human and the Earth
In terms of the evolution of life on Earth,human beings have just arrived.Despite their shori time on Earth,however,people have brought about enormous changes to the surface of the planet一changes far out of proportion to the interval of time they have occupied it.
People have more control over their surroundings than any other species on Earth.With the combination of intelligence and manual skill(allowing us to make and use tools),people have found ways to use plant and animal resources,mineral ores,fuels,and many other materials and resources from the Earth.
As the number of people on Earth increases,it becomes increasingly difficult for the population to survive on the resources of the land.The amount of land is limited.Although agricultural production can be increased by use of machinery such as tractors and the addition of fertilizer,the land ultimately can produce only so much food and no more.
As the human population grows,people consume more.Clearly,some locations on Earth already have too many people;in many of these areas,future increases will surely bring about more poverty and suffering. Yet people in rich nations use proportionally far more of the available resources than people in poorer nations.As they consume these resources without restraint,they also waste large amounts of them.
People are only a very small fraction of all the living things on the planet.Yet their numbers create a drain on resources that can't be renewed.For example,the amount of water on Earth is limited,this water is cleaned through natural processes.However,the natural processes for filtering water can clean only a certain amount of water by removing the pollution.Likewise,a limited amount of petroleum can be found under the Earth's surface.Petroleum is a valuable resource.Should people use it up to manufacture petrol for automobiles?As people work to control the planet and make life comfortable,are they using up resources that are needed for their survival?Why have people more control over their surroundings than any other species on Earth?
A:Because of their intelligence and manual skill.
B:Because they can use plant and animal resources,mineral ores and fuels.
C:Because they are cleverer than any other animals on Earth.
D:Both A and B.答案：D解析：文章第一段第一句话提到“就地球上生命的进化而言，人类是姗姗来迟者”，因此比较而言，人类的历史并不长。选项A是正确的。
从文章第二段第二句话“With the combination of intelligence and manual skill...”我们知道选项A和B都是正确的，因此选择D项。
文章第三段提到，土地的总量是有限的。虽然使用拖拉机等机械和施用化肥可以提高农业产量，但是土地最终所能产出的粮食只有那么多，不会再增加。因此只有选项C是正确的。
文章第四段第三句说富裕国家的人们所使用的能源在比例上远远大于贫穷国家的人们。选项C中提到的“发达国家的人们”最符合题意。
根据文章最后一段关于资源的描述我们可以发现选项A、B、C都是正确的，只有选项D的表述错误，因此选择D项。 -

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.According to the passage,which of the following statements about retired people in the United States is true?
A: Many of them have a very hard life.
B: They cannot live a decent life without enough bank savings.
C: They rely mainly on their children for financial support.
D: Most of them live with their children and therefore are well looked after.答案：A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”。 -

Living Alone Is Joyful More and more Americans are living alone.Some live alone because of divorce or the death of a partner. _______（46) According to a recent U.S.census（人口普查）,25 percent of all households in the U.S.are made up of just one person.This is dramatic change from the extended families of just a couple of generations ago. The typical person living alone is neither old nor lonely．
______(47)The majority of these people have chosen to live alone.They are responding to decreasing social pressure to get married and have a family.
It's now socially acceptable,even fashionable,to live alone.As people get better jobs and become financially independent,it becomes possible for them to maintain a one-person household.______(48)
However,people who do get married are marrying at a later age and divorcing more often. The number one reason given by most people for living alone is that they simply enjoy doing what they want when they want to do it."Living alone is a luxury,"says Nina Hagiwara,33."Once you do it,you can't ever go back to living with others,"David C'Debaca,46,agrees.
______(49) Children think that being grown up means being able to do exactly as they please._______(50) The chance to discover whether that freedom is as wonderful as it sounds is a chance more and more Americans are taking.______(49)
A:There's more pressure to get married nowadays.
B:The growing number of women with good jobs has done much to increase the number of people living alone.
C:However,even more people are living alone because they have chosen to.
D:It seems that many grown-ups today are realizing that childhood dream.
E:In fact,a quarter of the 23 million single people in the U.S.are under the age of 35.
F:He says,"I like being by myself."答案：F解析：在第一段开始，作者就提到“越来越多的美国人过着单身生活”，紧接着讲述了“一些人过着单身生活的原因是离婚或者配偶的去世”。选项中只有C项“更多的美国人过单身生活的原因是他们选择了这种生活方式”是与此相关联的。
前面一句话说“典型的独居人群既不是老年人也不是离异者”；后面一句话说“这些人中的大部分人选择了这一生活方式”，联系上下文可知，“这些人”指的不是前面所提到的老年人或离异者，而应该是本段最后一句话中所提到的“响应减轻社会压力而不结婚和组建家庭的人”，选项中只有E项“事实上，在美国2300万个单身的人中有1/4的人不到35岁”是与此相关联的。
前面一句话说“因为人们得到了更好的工作，经济上更加独立，所以他们才有可能维持一个人生活需要的开支”，而选项中只有B项“越来越多的女士有了好的工作，她们也使得独居人口的数量增加了”是与此相关联的。
前面一句话提到了一个人David C ' Debaca，他说“一旦你独居了，就很难再与他人生活在一起。”说明他已经可惯了这种生活方式，而选项中只有F项“他说他喜欢自己生活”是与此相关联的。
最后一段的第一句话说“儿童认为，长大意味着想干什么就干什么”，而选项中只有D项“似乎今天许多大人正在实现那种儿时的梦想”是与此相关联的。 -

B:They cannot live a decent life without enough bank savings.
C:They rely mainly on their children for financial support.
D:Most of them live with their children and therefore are well looked after.答案：A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减低，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，故选D。
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。 -

单选题From childhood to old age, we all use language as a means of broadening our knowledge of ourselves and the world about us. When humans first 1 , they were like newborn children, unable to use this 2 tool. Yet once language developed, the possibilities for human kind’s future 3 and cultural growth increased. Many linguists believe that evolution is 4 for our ability to produce and use language. They 5 that our highly evolved brain provides us 6 an innate language ability not found in lower 7 . Proponents of this innateness theory say that our 8 for language is inborn, but that language itself develops gradually, 9 a function of the growth of the brain during childhood. Therefore there are critical 10 times for language development. Current 11 of innateness theory are mixed, however, evidence supporting the existence of some innate abilities is undeniable. 12 , more and more schools are discovering that foreign languages are best taught in 13 grades. Young children often can learn several languages by being 14 to them, while adults have a much harder time learning another language once the 15 of their first language have become firmly fixed. 16 some aspects of language are undeniably innate, language does not develop automatically in a vacuum. Children who have been 17 from other human beings do not possess language. This demonstrates that 18 with other human beings is necessary for proper language development. Some linguists believe that this is even more basic to human language 19 than any innate capacities. These theorists view language as imitative, learned behavior. 20 , children learn language from their parents by imitating them. Parents gradually shape their child's language skills by positively reinforcing precise imitations and negatively reinforcing imprecise ones. 请在11处填上正确答案（）Areviews

In terms of the evolution of life on Earth,human beings have just arrived.Despite their shori time on Earth,however,people have brought about enormous changes to the surface of the planet一changes far out of proportion to the interval of time they have occupied it.
People have more control over their surroundings than any other species on Earth.With the combination of intelligence and manual skill(allowing us to make and use tools),people have found ways to use plant and animal resources,mineral ores,fuels,and many other materials and resources from the Earth.
As the number of people on Earth increases,it becomes increasingly difficult for the population to survive on the resources of the land.The amount of land is limited.Although agricultural production can be increased by use of machinery such as tractors and the addition of fertilizer,the land ultimately can produce only so much food and no more.

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”。 -

Living Alone Is Joyful
More and more Americans are living alone.Some live alone because of divorce or the death of a part-
ner._______ (46) According to a recent U. S. census（人口普查）,25 percent of all households in the
U.S.are made up of just one person.This is a dramatic change from the extended families of just a couple
of generations ago.
The typical person living alone is neither old nor lonely._______(47) The majority of these people
have chosen to live alone. They are responding to decreasing social pressure to get married and have a family.
It's now socially acceptable, even fashionable, to live alone.
As people get better jobs and become fi-
nancially independent, it becomes possible for them to maintain a one-person household._______(48)
However, people who do get married are marrying at a later age and divorcing more often.
The number one reason given by most people for living alone is that they simply enjoy doing what they
want when they want to do it.
"Living alone is a luxury,"says Nina Hagiwara, 33.
"Once you do it, you
can't ever go back to living with others. " David C' Debaca, 46, agrees._______(49)
Children think that heing grown up means being able to do exactly as they please._______(50)
The chance to discover whether that freedom is as wonderful as it sounds is a chance more and more Ameri-
cans are taking._________(49)
A: There's more pressurP. to geL married nowadays.
B: The growing number of women with good jobs has done much to increase the number of people living alone.
C: However, even ruore people are living alone because they have chosen to.
D: It seems that many growii-ups today are realizing that childhood dream.
E: In fact, a quarter of the 23 million single people in the U. S.are under the age of 35.
F: He says, "I like being by myself. "答案：F解析：在第一段开始，作者就提到“越来越多的美国人过着单身生活”，紧接着讲述了“一些人 过着单身生活的原因是离婚或者配偶的去世”在几个选项中，只有C选项与前文相照应，因为 C选项提到了美国人过单身生活的其他原因二故选C。
从第二段的第一句话，我们很容易看出本段叙述单身生活的人群。第一句话指出“典 型的单身者既不是老年人也不是离异者”，那么在其后面肯定是说明这些典型的．单身者到底是 什么人。在几个选项里面，只有E提到了人群，即“事实上，在美国，2300万单身者中，有四分 之一的人处于35岁以下”：故选E。
本题可以用排除法解决。首先本段主要叙述单身生活被社会所接受以及各种成因，主 要是因为人们得到了更好的工作，经济上更加独立等。但该段没有提及pressure（压力）,child- hood dream（儿时梦想），故排除A和D；在F中的He没有前后呼应的主语，故将其排除。只有 B选项与本段内容相符。
第四段的倒数第二句话提到了一个人物David C' Debaca，所以能与人物相对应的只有 F选项中的He。
最后一段的第一句话说：儿童认为，长大意味着想十什么就于什么。选项D的意思是： 似平今天许多大人正在实现那种儿时梦想。第6部分：完形填空 -

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,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 underskilled 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：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减低，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，故选D。
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。 -
