nity that John hadn’t learned to drive.
有三类句子成分不可以进行强调，即表语、谓语动词和由though， although，whereas等引导的从句。
It is although he is young that he can speak four languages. （误）
Although he is young， he can speak four languages. （正）
It is whereas he prefers pop song that I like classical music. （误）

3. 使役动词后的宾语补足语
使役动词除了要有宾语之外还要加上宾语补足语才能使句子的意义完整。常用的使役动词有：have， want， make， get， leave， set， let等。可以担当使役动词宾语补足语的有名词，形容词，介词短语，动词不定式和分词等。
All work and no play makes Jack a dull boy.
A good night’s rest will set you right.
Note：
动词不定式可以担当使役动词的宾语补足语，但在make， let， have等使役动词后，动词不定式作宾语补足语时不用to。
He made her give up the opportunity.
What would you have me do？
Her pride would not let her do this.
分词也可以担当使役动词的宾语补足语。现在分词表示正在进行的主动意义，而过去分词表示已经完成的被动意义。
Her remark left me wondering what he was driving at.
The joke set them all laughing.
He managed to get the job done on time.
I’ve just had some new photos taken.
4. 平行结构
在英语中，当两个或两个以上的同等成分（主语，谓语，宾语，表语，定语，状语，宾语补足语等）并列时，要求它们的词性或结构相同，即名词对名词，介词短语对介词短语，分词对分词，句子对句子等等。这就是英语的平行结构准则。一般在使用并列连词如and， but， or， neither … nor， either … or， not only 。. but also， both … and， more（less） … than， as well as，rather… than等时，要注意不要违反平行结构准则。
He likes watching TV more than reading books.
The soldier preferred to die rather than surrender.
We saw Tom walking towards the river， taking off his clothes and plunging into the water.
Censorship prevents a movie from being shown or a book being sold.
5. 反意疑问句
在具体运用反意疑问句时应注意以下几点：
1） 如果陈述句部分是一个含有宾语从句的复杂句，则反意疑问部分的谓语动词和主语代词要与主句的谓语动词和主语相对应。
He never said she would come， did he？
You told me I had passed the exam， didn’t you？
但是如果陈述句部分是 “I （don’t） think， believe， suppose， imagine， expect， fancy， reckon等+宾语从句”的结构时，反意疑问部分的谓语动词和主语代词要与宾语从句的谓语动词和主语相对应，并且要注意否定的转移。
I suppose you are not serious， are you？
