5).无主题句，即主题句隐含在全文中, 没有明确的主题句. 必须根据文篇中所提供的事实细节，进行全面考虑，综合分析，然后找出共同的东西，归纳成一般概念。必须注意的是，既不能以偏概全，也不能在概括时过于宽泛，要恰如其分。

例6.Joshua Bingham studied 4 years at the University of Paris and decided to leave his graduation. He transferred to the University of Berlin and graduated with honors. Harvard Law School and, later, Boston College provided him with an excellent legal background. He is presently a corporation lawyer in Miami, Florida.

Q: What is the main idea of the passage?　____

A. How Joshua Bingham became a lawyer. B. Bingham is a diligent student.

C. Joshua Bingham received an excellent education. D. A good lawyer needs good education.

[分析]此文没有主题句。全篇共四句，只陈述了四个细节(detail)性的事实。因此就答案本身看，个个都对。读者只能将所有的 details综合起来，进行逻辑推理，才能构成一个没有言明的主题思想(unstated main idea)。由于文中主要涉及了Joshua Bingham接受教育的情况，即作者想告诉我们的是：Joshua Bingham接受过良好的教育，所以答案是 C

除了以上主题句呈现的常见形式外还要注意标志词

文章或段落的主题句常常会出现在一些标志性的提示后。如：on the whole, as a result, in short, therefore, thus…..I agree with the opinion that….;Given all these points above, I would support the idea that….; For all the reasons mentioned above, I would prefer….

例3：A university graduate described as a “respectable and intelligent” woman is seeking professional help after being convicted of (证明有……罪)shoplifting for the second time in six months.

Ana Luz, recently studying for her PhD,has been told she could end up behind bars unless she can control the desire to steal from shops .

Luz ,who lives with her partner in Fitzwilliam Road ,Cambridge ,admitted stealing clothes worth ￡9.95 from John Lewis in Oxford Street ,London ,on March 9.

Phillip Lemoyne ,prosecuting(起诉),said Luz selected some clothes from a display and took them to the ladies’ toilet in the store .When she came out again she was wearing one of the skirts she had selected ,having taken off the anti-theft security alarms(防盗警报装置).

She was stopped and caught after leaving the store without paying ,Mr Lemoyne said.

He added that she was upset on her arrest and apologized for her actions.

Luz,28, was said to have been convicted of shoplifting by Cambridge judges last October ,but Morag Duff, defending ,said she had never been in trouble with the police before that .

“She is ashamed and embarrassed but doesn’t really have any explanation why she did this ,” Miss Duff said . “She didn’t intend to steal when she went into the store .She is at a loss to explain it . She is otherwise a very respectable and intelligent young lady .She went to her doctor and asked for advice because she wants to know if there is anything in particular that caused her to do this.”
