b) 由固定词组引导的疑问句：

What about having a game of chess? 下盘棋怎么样?

How come they left you alone here? 他们怎么会把你一人留在这里呢?

What if it’s raining? 如果天下雨怎么办?

Why not try again? 为什么不再试试呢?

c) 在口语中，为了避免重复，不定式可以省去和句子前部重复的动词原形而只留下不定式符号to。

He may leave if he wishes to. 他可以走，如果他愿意的话。

Don’t go till I tell you to. 等我叫你走你再走。

5 被省略的部分一般可以在句子中补上，但有时省略结构已经定型，如果把省略部分补上，反而不合乎习惯。

He is taller than I am. 他比我高。(am之后省略tall，补上不合习惯)

No parking. 禁止停车。(告示用语 = No parking is allowed here.)

有一些习惯表达很难补上所省略的部分：

Not at all. 不用谢。

No matter. 不要紧。

Thanks. 谢谢。

5. Looking back
