Washington,  April 4-The United States has more than 90 million families for the first time,  but each contains fewer people on average than ever,  the Census Bureau(统计局) reported today.
The 90, 031, 000 families in the United States averaged 2. 64 members each as of last July 1.
“The reason is,  in effect,  changes in the age structure, ” explained Campbell Gibson,  a population researcher for the bureau.  Most Americans born in the great  explosion of births after World War Ⅱ are now in their 20's and 30' when they are most likely to set up families,  he said.
The fact that many are doing so increased the number of families from 80. 4 million in 1980 to 88. 8 million in 1986 and past the 90 million mark last summer.
At the same time,  the average number of people per family dropped from 2. 75 in 1985 to 2. 65 in 1986 and then to 2. 64,  Mr. Gibson said.
By comparison,  the 1970 Census found the average family contained 3. 14 people.  Families averaged more than four people in 1939 and more than five in 1880.
The growing number of even-smaller families is still going on,  but Mr. Gibson pointed out that family growth was not the same as population increase in the 1970' s.
The same age factors that are increasing the number of families also happened then,  but in the 1970's the proportion(比例) of families in each age group was also growing.
The year that hasn't continued is the 1980's for a number of possible reasons,  Mr. Gibson said.
For example,  in the 1980's more young people have chosen to remain home with their parents instead of setting up house keeping on their own,  as many did in the 1 970's.
This could be caused by the increasing cost of housing,  he said.  Delays in marriage while young people go to work and school,  have also been widely reported as a factor,  but it was not the only factor for the family changes. 
36. The smaller figure of families reported here is          .
A. 1980          B. 80, 400, 000         C. 2. 64          D. 90 million
37. How did Mr. Gibson explain the reason of the increase in families?
A. About 0. 96 million new families have been set up since 1980.
B. All the big families were split into smaller ones.
C. There is a great number of young people who are newly married.
D. There was a great explosion of births during the Second World War.
38. What's the reporter's attitude towards the present situation?
A. People should get married at a later age.
B. The average number of family members should be 2. 64.
C. It's not clear in the report.
D. Young people should set up housekeeping on their own,  as many did in the 1970's.
39. From the last paragraph we may infer that  .
A. delay in marriage will not help the number of the families
B. delay in marriage is the major factor of the family changes
C. the writer felt sorry that many young people now delay their marriages
D. there must be some other factors which have led to the slower growth in the 19 80's.
40. The underlined word “factor” in the passage means .
A. reason       B. something that proves to be true
C. advantage    D. something that helps to bring about a result

    Scientists hope that if we can discover how the brain       41.       
works,  we sill be able to put it better use.  For example,     42.       
how do we learn language?  Man differs mostly all             43.       
the other animals in their ability to learn and use             44.       
language,  but we still do not know exact how this is done.      45.       
Some children learn to speak and read and write quickly          46.       
than others.  But scientists are not sure why that this          47.       
happens.  They are trying to find whether there is              48.       
something about the way we teach language to the children        49.       
that is fact prevent them from learning more quickly.          50.

He had to provide for the large family.  他必须赡养这个大家庭。
联想迁移
(1)过去分词provided和现在分词providing可起连词作用，其后跟可以省略that的从句，用来表达“在……条件下，倘若”之意。e. g. 
①Provided(that) there is no opposition,  I will act as representative of our class.  倘若没有反对的话，我将担任本班的代表。
②I shall go providing(that) it doesn't rain.  倘若不下雨，我就去。
(2)表示“供给”之意，还可使用动词短语to supply sb.  with sth.  或supply sth .  to sb. 。 e. g. 
The government decided to supply the refugees with houses. 
＝The government decided to supply houses to the refugees. 
政府决定供给难民住房。
8. He already knew what he wanted to be when he grew up.
他已经知道他长大后，该干什么。
(1)这是一个主从复合句，主句是He already knew. . . 。由what引导的从句是宾语从句，在句中作knew的宾语，when he grew up是一个时间状语从句，在句中作to be的状语。
【重点难点解析】
1.  All through his life Einstein was content to spend most of his time alone.
在他整个一生中，他乐意孤身一人度过他的大部分时光。
(1) content为形容词，作“满足的，满意的，甘愿的”解。be content to do sth.  
表示“愿意、乐意做某事”，相当于be willing or ready to do sth. 。e. g. 
I should be well content to do so.  我很愿意这样干。
(2) content还可以作动词用，一般为及物动词，常用content sb. /oneself(with)  这个词组。e. g.
We should never content ourselves with book knowledge only.
我们切不可满足于仅仅有一点书本知识。
(3) content作不可数名词用时，意为“满足”或表示满意的状态。e. g. 
Now she began to live in peace and content.
现在她开始生活平静而满足。
习惯搭配
(1)表示“满足于”的意思，除可用to content oneself with这一动词词组外，还可用形容词短语形式to be content with。e. g. 
Are you content with your present salary?  你对现在的薪水满意吗? 
(2) content常作名词，用于to one's heart's content短语中，意为“尽情地”。e . g. 
We can swim in the river to our heart's content. 
我们能够在这条河里尽情游泳。
2.  When he was a young boy he used to ask lots of questions. 
他小时候经常提出许多问题。
(1) used to+动词原形，意为“过去经常”。e. g.
He is not what he used to be.  他已不是从前的他了。
(2) used to的否定式为used not或didn't use. 疑问句可用used开头，也可用did开头。e. g.
①He usedn't/didn't use to come.  他过去不常来。
②You used to go there,  usedn't/didn't you?
你过去常到那里去，不是吗? 
3.  It was said that he found in music the peace which was missing in a world full of wars and killings. 
据说，他从音乐中找到了在充满战争与屠杀的世界里所失去的和平。
(1)这是一个由引导词it引导的句子，it是形式主语，that从句是真正的主语，在that从句中又有一个主从复合句，其中主句是he found. . . peace，后跟一个由which引导的定语从句，先行词为peace，介词短语in music作状语。
(2)full of是形容词短语(相当于filled with)，作“充满”解释。
(3)missing在这里是形容词，意为“失去的，找不到的”。
4.  The difficulty was how he could prove his ideas to other  scientists.
困难在于怎样才能向其他科学家证明他的想法。
由连接副词how引导的从句how he could prove his ideas to other scientists是表语从句。
其他连接副词如when,  where,  why,  because等也可以引导表语从句分别用来说明时间、地点、因果等事实。本课最后一句就是很好的例子：
That is why Einstein and his family left Europe for the USA in 1933. 
那就是爱因斯坦和他的家人于1933年离开欧洲去美国的原因。
另外，连接代词that,  what也可以引导表语从句。

【阅读分析点拨】
Most animals have little connection with animals of a different kind,  unless they hunt them for food.  Sometimes,  however,  two kinds of animals come together in  a partnership(伙伴关系) which does good to both of them.  You may have noticed some birds sitting on the back of sheep.  This is not because they want a ride,  but  they find easy food in the parasites(寄生虫) on sheep.  The sheep allow the birds to do so because they remove the cause of discomfort.  So although they can manage without each other,  they do better together.
Sometimes an animal has a plant partner.  The relationship develops until the two  partners cannot manage without each other.  This is so in the corals(珊瑚) of the sea.  In their skins they have tiny plants which act as “dustman”,  taking some of the waste products from the coral and giving in return oxygen which the animal needs to breathe.  If the plants are killed,  or are even prevented from light  so that they cannot live normally,  the corals will die.
1. Some birds like to sit on a sheep because           .
A. they can eat its parasites
B. they depend on the sheep for existence
C. they enjoy travelling with the sheep
D. they find the position most comfortable
解析  这是一道细节题。答案是A。文中You may have noticed some birds sitting on the backs of sheep.  This is not because they want to ride,  but because they find easy food in the parasites on sheep.  便是该题的信息。
2. The underlined word “they” in the last sentence of the first paragraph refers to               .
A. birds and parasites            B. birds and sheep
C. parasites and sheep            D. sheep,  birds and parasites
解析  这是一道所指题。划线单词系指鸟和羊，故B为答案。
3. It can be learnt from the text that the coral depends on the plant for         .
A. comfort      B. light      C. food      D. oxygen
解析  这是一道判断题。从文中In their skins they have  tiny plants which act as “dustman”,  taking some of the waste products from the coral and giving in return oxygen which the animal needs to breathe.  一句可以得出结论，D为该题的正确答案。
4. What does the second paragraph mainly discuss?
A. Some animals and plants depend on each other for existence
B. Some animals and plants develop their relationship easily
C. Some pants depend on each other for food
D. Some animals live better together.
解析  该题要求考生找出第二自然段的中心思想。本段通过例举珊瑚来证明动植物为了生存而相互依靠，故A为最佳答案

【命题趋势分析】
例1  Those who are not               with the progress they have made will have greater success.
A. proud         B. afraid         C. popular          D. content
分析  答案为D。be proud of以……为自豪；be afraid of 怕……；be popular with 受……欢迎。
例2            she couldn't understand was           fewer and fewer students showed interest in her lessons.
A. What;  why      B. That;  what      C. What;  because      D. Why;  that
分析  答案为A。understand为及物动词，其后无宾语，故应 选择连接代词what。因为主语从句已具有否定意义，表语从句意义不完整，所以由句意可知，表语从句需用why。
例3  Premier Zhou          to be unforgettable in the  hearts of Chinese people.
A. proved         B. regarded        C. thought          D. considered
分析  答案为A。sb.  be regarded(thought) to be+n. (adj.  );  regard sb.   as+n. (pron. )把……当作……。故不能选择B、C、D。prove为连系动词，不定式作表语。
