就整篇文章来讲，首段和尾段一般对于解这类题更为重要。我们以97年统考试卷中阅读理解部分的第一篇文章为例：

　　How often one hears children wishing they were grown up, and old people wishing they were young again. Each age has its pleasures and its pains, and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets.

　　Childhood is a time when there are few responsibilities to make life difficult. If a child has good parents, he is fed, looked after and loved ,whatever he may do .It is impossible that he will ever again in his life be given so much without having to do anything in return .In addition ,life is always presenting new things to the child——things that have lost their interest for older people because they are too well-know. But a child has his pains: he is not so free to do what he wishes to do; he is continually being told not to do things, or being punished for what he has done wrong.

　　When the young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time playing about in the way that he used to as a child, he will go hungry. And if he breaks the laws of society as he used to break the laws of his parents, he may go to prison. If however, he works hard, keeps out of trouble and has good health, he can have the great happiness of building up for himself his own position in society.

　　文章后面第四个问题是：

　　The main idea of the passage is that _____.

　　A. life is not enjoyable since each age has some pains

　　B. young men can have the greatest happiness if they work hard

　　C. childhood is the most enjoyable time in one's life

　　D. one is the happiest if he can make good use of each age in his life

　　文章的第一段讲的是人们常听说孩子们盼着长大成人，老年人则希望返老还童。人生的每个阶段总是欢乐伴着苦恼，而最幸福的人则是那些既享受人生每一阶段所带来的欢乐，又没有因虚度年华而终生后悔的人。第二段讲述了一个人儿童时代的欢乐与苦恼，第三段则告诉读者青年人的责任与义务，机遇和挑战。从以上三段文字来看，第一段中第二句即是主题句，所以我们应选D为正确答案。

　　(2) 主要事实和细节题设题思路及答题技巧

　　主要事实和细节题就是我们平时所说的由who ,what ,where ,when ,why ,which ,how引出的问题。这是极为常见的阅读理解题。这类题主要是针对论证支持主题的事实或例证设题，可能涉及数学计算、概念理解以及是非判断等。

　　这类题的方法一般是先用寻读法找出与问题相关的词语或句子，再对相关部分进行细读，找出问题答案。

　　这类题提问的形式多种多样，常见的有以下几种：

　　Which of the following (statements) is Not mentioned in the passage?

　　According to the passage，which of the following statements is true?

　　According to the passage, all of the following are true except _____

　　How many…？

　　What…?

　　Why…?

　　解这类题时，审题是关键，首先一定得看清问题。比如一句结论性的话后边到底是…is true,还是is not true.另外，由于细节题比较容易，有时为了增加测试难度，命题人员在题干或选项中要增加一些文字或意义上的干扰。所以考生很少能在原文中找到一模一样的现成答案。
