Unit 4 A Good Read

Grammar

学习目标

1. 学会正确使用“特殊疑问句+动词不定式”的结构。

2. 学会正确使用must和have to。

重难点

能在语境中正确运用“特殊疑问句+动词不定式”的结构与must/have to。

特殊疑问词+动词不定式

（1）此结构由疑问代词who, whom, what, which或疑问副词when, where, how等后接动词不定式构成。如：Are you sure when to use this word?你清楚什么时候使用这个单词？

（2）此结构的用法

作宾语。常用的动词有：advise, ask, consider, decide, discuss, explain, forget, know, learn, remember, show, teach, tell, wonder等。如：

我们还没有决定去哪儿呢。你能建议我怎么选择吗？

We haven’t decided where to go. Could you advise me how to choo se?

作主语。如：

When to have a meeting is a question.什么时候开会还是一个问题。

作表语。如：

My question is whether I need to take passport with me .我的问题是我是否需要带上签证。

must和have to

（1）must意思是“必须”，表示说话人的主观看法，即主观上认为有义务、有必要去做某事。Must没有时态和人称的变化，主要用于肯定句和疑问句，其否定形式mustn’t表示“不应该、禁止、不允许”。

（2）have to意思是“不得不”，表示客观方面的“必须”，即客观地、被迫地去做某事。Have to有时态和人称的变化，其否定形式does/do/didn’t have to表示“没必要”，相当于needn’t。

他们必须搞清楚谁上交了我的读书报告。
