Why So Many ChildrenIn many of the developing countries in Africa and Asia,the population is growing fast.The reason for this is simple:Women in these countries have a high birth rate—from 3 .0 to 7.0 chil-dren per woman.The majority of these women are poor,without the food or resources to care for their families .Why do they have so many children?Why don't they limit the size of their fami-lies?The answer may be that they often have no choice.There are several reasons for this.One reason is economic .In a traditional agricultural economy,large families are helpful. Having more children means having more workers in the fields and someone to take care of the parents in old age.In an industrial economy,the situation is different.Many children do not help a family;instead,they are an expense.Thus,industrialization has generally brought down the birth rate .This was the case in Italy,which was industrialized quite recently and rapidly.In the early part of the twentieth century,Italy was a poor,largely agricultural country with a high birth rate .After World War Ⅱ,Italy's economy was rapidly modernized and industrialized.By the end of the century,the birth rate had dropped to 1.3 children per woman,the world's lowest.However,the economy is not the only important factor that influences birth rate.Saudi Ara-bia,for example,does not have an agriculture-based economy,and it has one of the highest per capita incomes in the world.Nevertheless,it also has a very high birth rate(7.0).Mexico and Indonesia,on the other hand,are poor countries,with largely agricultural economies,but they have recently reduced their population growth.Clearly,other factors are involved.The most important of these is the condition of women.A high birth rate almost always goes together with lack of education and low status for women.Thiswould explain the high birth rate of Saudi Arabia .There,the traditional culture gives women little education or independence and few possibilities outside the home.On the other hand,the im-proved condition of women in Mexico,Thailand,and Indonesia explains the decline in birth rates in these countries.Their governments have taken measures to provide more education and oppotunities for women.Another key factor in the birth rate is birth control.Women may want to limit their families but have no way to do so．In countries where governments have made birth control easily available and inexpensive,birth rates have gone down.This is the case in Singapore,Sri Lanka,and India，as well as in Indonesia,Thailand,Mexico,and Brazil.In these countries,women have also been provided with health care and help in planning their families．These trends show that an effective program to reduce population growth does not have to de-pend on better economic conditions.It can be effective if it aims to help women and meet their needs .Only then,in fact,does it have any real chance of success． In a traditional agricultural economy，a large family____．A: can be an advantageB: may limit incomeC: isn't necessaryD: is expensive答案：A解析：本题的问题是：在传统的农业经济中，大的家庭的影响是什么？从文中第二段第二句和第三句话可以得出明确的答案。“ In a traditional agricultural economy , large families are helpful.Having more children means having more workers in the fields and someone to take care of the parents in old age.”所以答案为A，是优势。 本题的问题是：当国家工业化后，人口和出生率的状况是什么？从第二段意大利的例子可以明确得出答案。“In the early part of the twentieth century , Italy was a poor, largely agricultural country with a high birth rate.After World War Ⅱ,Italy's economy was rapidly modernized and industrialized.”由此可见出生率降低。 本题的问题是：本文举出意大利的例子要说明什么？从第二段意大利的前后对比的情况可以看出正确答案为A。 本题的问题是：文中提到沙特阿拉伯的例子说明了什么？ 由第三段开头可知“However , the economy is not the only important factor that influences birth rate.”下面将要介绍其他的因素，之后以沙特阿拉伯为例。故正确答案为B。经济以外影响出生率的因素。 本题的问题是：墨西哥、泰国、印度尼西亚的政府采取了怎样的措施？从文中第四段后半部分“On the other hand , the improved condition of women in Mexico , Thailand, and Indonesia explains the decline in birth rates in these countries.Their governments have taken measures to provide more education and opportunities for women.”可以得出结论。另一方面从第四段开头也可以得出结论。“ The most important of these is the condition of women.”之后举出这几个国家的例子，从而也可以得出结论。

Children for whom school has no point
Many children do not go to school either because their parents want them at home as carers for siblings,or simply because their parents cannot be bothered to send them．Thousands more are not registered at any school at all,because of their families'unstable lives.
Underlying this dreadful situation there are two central truths．First of all,the problem of children not going to school often has more to do with their parents than with the children themselves．Secondly,once children go to school,we need to make sure that the experience is a positive one so that they want to keep on going.
In Britain,the Ministry of Education has introduced a complex package of sticks and carrots to persuade Schools to bring truants'and excluded children back into the classroom．It is paying grants so that a thousand schools can set up special units to help these children．Schools receive the grant if they bring a target number of children back to school;if they do not meet the target,the grant is withdrawn.
Parents are the subject of this campaign,too:the Home Office has introduced fines for parents who fail to send their children to school,and has given the police power to pick up truants on the streets.
Truant=a child who does not go to school when he or she should.Part of the problem is__.A.that people feel very emotional
B.that parents worry their children at school
C.that these children think education is a waste of time
D.that there are not enough police to pick up truants on the streets答案：C解析：第二段。最后一句中的positive experience意为“有用的知识”。全句大意是“对孩子来说，如果在学校学到的知识对他们有用，他们将愿意在学校学下去”，而不是去浪费时间。

The Sandwich GenerationToday people often look forward to their middle age as a time when they will be able to take things easier. After their children are grown,they expect to enjoy the life they have worked hard to create .However,the reality is often very different. In middle age,many people discover that they have two ongoing responsibilities:one is to look after their aging parents,and the other is to help their young adult children deal with the pressures of life.Around the world,there are mil-lions of people who are“sandwiched”in between the older and the younger generations.Some-times there may be two or three generations living in the same household-a situation that is corn-mon in many Asian countries and in some parts of Europe .In other cases,a couple may be taking care of parents and children,but they do not live with them.There are two important reasons for the rise of the sandwich generation.First,people are liv-ing longer than they used to.In the early nineteenth century,the average life expectancy for adults in the United States,for example,was about 40,whereas today people live to an average age of 75 .Therefore,children are taking care of their parents over a longer period of time.The see-ond reason is that these days,young adults often live with their parents for a longer time than they did in the past. This is often for financial reasons.It's also more common for today's young adults to return home during or after college if they need financial or emotional support.Young adults feel sandwiched between their financial responsibilities and their desire to enjoy life .They may have to cover expenses that their parents cannot.They may have to manage their parents' financial and legal affairs.They may have to prepare for their parents' future needs,such as special medical care or a move to a nursing home. This can be a traumatic（长期困扰的）ex-perience for everyone.Caring for adult children presents challenges as well,and caregivers have to resolve important questions:How can financial responsibilities be shared among members of the household?How can household chores be shared?What is the best way to ensure everyone's privacy?Successfully cop-ing with these issues can avoid a lot of stress for the whole family.The financial and emotional pressures on the sandwich generation can be overwhelming. However,this time in life also has its rewards.It can be a time to rediscover the special qualities of one's parents or children.It can also provide a valuable opportunity to spend more time with them. However,in order to survive this difficult period in their lives,the members of the sand-wich generation must remember that they also need to pay attention to their own needs and look af-ter the quality of their own lives.They can't be totally selfless. Why do some young adults choose to live with their parents these days?A:.They need support from their parents to deal with their financial problems.B:.They want to help their parents to take care of their aging grandparents.C: They are too young to be independent from their parents.D: They are more emotional than the young adults in the past.答案：A解析：由第一段第二、三句“After their children are grown , they expect to enjoy the life they have worked hard to create. However , the reality is often very different.”可知以此推断，很多中年人不能如愿地享受生活。故选B。 由第一段第四句“In middle age , many people discover that they have two ongoing re-sponsibilities:one is to look after their aging parents,and the other is to help their young adult children deal with the pressures of life.”及第五句“Around the world , there are mil-lions of people who are'sandwiched'in between the older and the younger generations.”可知，中年人在对父母和对孩子的责任中左右为难。故选B。 由第二段最后三句“The second reason is that these days , young adults often live with their parents for a longer time than they did in the past.This is often for financial reasons.It's also more common for today's young adults to return home during or after college if they need financial or emotional support.”可知，如今一些年轻人之所以会更久跟父母住在一起，是因为他们需要父母的经济或情感支持。故选A。 由第四段中的“caregivers have to resolve important questions : How can financial respon-sibilities be shared among members of the household?How can household chores be shared? What is the best way to ensure everyone's privacy?”可知，只有（决定谁来照料家庭）不是三明治一代要考虑的问题。故选C。 由最后一段最后两句中的“they also need to pay attention to their own needs and look after the quality of their own lives. They can't be totally selfless.”可知，要度过这个艰难的人生阶段，三明治一代需要考虑自身的幸福。故选B。

The FamilyThe structure of a family takes different forms around the world and even in the same society.The family's form changes as it adapts to changing social and economic influences.Until recently, the most common form in North America was the nuclear family,consisting of a married couple with their minor children.The nuclear family is an independent unit.It must be prepared to fend for itself. Individual family members strongly depend on one another. There is little help from outside the family in emergencies.Elderly relatives of a nuclear family are cared for only if it is possible for the family to do so.In North America,the elderly often do not live with the family;they live in retirement communities and nursing homes.There are many parallels between the nuclear family in industrial societies,such as NorthAmerica,and of families in societies such as that of the Inuits,who live in harsh environments.The nuclear family structure is well adapted to a life of mobility. In harsh conditions,mobility allows the family to hunt for food.For North Americans,the hunt for jobs and improved social status also requires mobility.The nuclear family was not always the North American standard.In a more agrarian time,the small nuclear family was usually part of a larger extended family.This might have included grandparents,mother and father,brothers and sisters,uncles,aunts,and cousins.In North America today,there is a dramatic rise in the number of single-parent households.Twice as many households in the United States are headed by divorced, separated,or never-married individuals as are comprised of nuclear families. The structure of the family,not just in North America,but throughout the world,continues to change as it adapts to changing conditions.According to the passage,which is the definition of a nuclear family?A:.A nuclear family is a married couple with their minor children.B: A nuclear family is a single father with minor children.C: A nuclear family concludes parents,grandparents,and children.D: A nuclear family concludes parents,children,and aunts and uncles.答案：A解析：主旨题。题干意为“下面哪个选项可以作为这篇短文另一个合适的标题？”。短文开篇就提到了家庭结构，短文最后一句意为“不仅在北美洲，在全世界范围，家庭结构都会随着情况的不断变化而改变。”由此可见这篇短文的主题与家庭结构相关，由此可以进一步确认答案为A“家庭的结构是什么”。 细节题。题干意为“根据文章，哪个是核心家庭的定义？”。第一段的第三句话对于核心家庭进行了定义Until recently , the most common form in North American was the nu-clear family , consisting of a married couple with their minor children.该句意为“直到最近，北美洲最普遍的家庭形式为核心家庭，由一对夫妇和他们未成年的孩子构成”。由此可知A“核心家庭是由一对夫妇和他们未成年的孩子构成的家庭”是答案。 主旨题。题干意为“这篇文章最有可能出自哪里？”。该短文主题涉及家庭，因此最有可能出自人类学课本，所以A是正确的答案。 题干意为“第一段主要以何种方式陈述的？”根据第一段的陈述方式，并没有列出数据或者讲故事，而是通过描述共性而阐述出核心家庭的概念。因此C“指出相似性”是正确的答案。 题干意为“mobility是什么意思？”mobility是mobile“可移动的，机动的”的名词形式。首先在短文中找到mobility存在的语境：第二段中“The nuclear family structure is well adapted to a life of mobility…the hunt for jobs and improved social status also re-quires mobility. ”mobility所在的上下文意为“核心家庭结构良好地适应于……的生活。在恶劣的条件下，……能让一个家庭吃饱饭，时北美洲人来说，找工作和提高社会地位同样需要……”四个选项中，A意为“钱”,B意为“随时准备迁居”，C意为“组织，机构”,D意为“技能，技巧”，显然B“随时准备迁居”填入mobility所在的语境中合适，因此答案为B。
