常考英语句型: 表示请求或建议

表请求/表建议句型

一、动词原形类

1. Let sb. do sth. 让某人做......

举例:

①Let'sgoswimming.让我们去游泳吧。

②Let themcleanthe classroom.让他们打扫教室。

③Let Tomwashhis clothes by himself.让Tom自己洗衣服。

注意:

①Let's=Let us

②Let sb. do sth.属于祈使句里重要句型之一。

③根据动宾结构,let后加人称代词时,要用宾格。

2. Why not do sth.? =Why don't you/we do sth.?为什么不做某事?

举例:

①Why notgoswimming?为什么不去游泳呢?

②Why don’t youhavea rest?你为什么不休息一下呢?

注意:

①Why not直接加动词原形,没有人称主语。

②加入助动词否定式don’t,不要漏了人称主语,常用you /we。

3. Shall I/we do sth.?我们可以做......?

举例:

①Shall Iopenthe door?我可以开门吗?

②Shall wehavesupper with you?我们可以和你吃晚饭吗?

注意:

①shall表示建议或请求语气的程度,较委婉,不要翻译为应该。

②shall常用第一人称I/we。

4. You had better do sth. = You'd better do sth. 你最好做......

举例:

①Tom had betterhavea rest. Tom最好去休息一下。

②You’d betternot sleep.你最好不要睡觉。

注意:

①You had=You’d, had better没有人称、时态、数的变化。

②had better do sth.否定是had betternot dosth.最好不要做某事。

二、to do 类型

5. would like to do sth.= want to do sth. 想要做某事

举例:

①What would you liketo drink? = What do you want to drink?你想要喝什么?

②Tom would liketo bea teacher. =Tom wants to be a teacher. Tom想要成为一名老师。

注意:

①would like没有人称、数、时态的变化。

②would like to do的否定形式是would not like to do=wouldn’t like to do。

③Would...like to ...?常用回答:

肯定回答→Yes, I would loveto./Yes, I would liketo.其中I would = I’d。

否定回答→No, thanks.

④注意区分(考试易错点)

would+动词原形,此时would为will过去式,常用于过去将来时的句子或表请求/建议的句子。比如:

①Tom asked if Linda wouldhelp. Tom问Linda是否会帮忙。

②Would you pleaseopenthe door ?你可以开门吗?(这类题考试经常挖坑,很多人会把would like to do和would do用法混淆,然后就掉坑了......)

6. It's a good idea to do sth. 做某事是个好主意。

举例:

①It’s a good idea to go swimming.游泳是个好主意。

②It’s a good idea to have a rest.休息一下很不错。

注意:

①It在句型It's a good idea to do sth.中作形式主语,真正的主语是to do sth.

②实际写作中还可以把a good idea替换为形容词,变成加分句型It’s+adj.+to do sth.

三、doing类型

7. What about doing sth.? = How about doing sth.? 做某事怎么样?

举例:

①What about swimming?游泳怎么样?

②How about drinking juice?喝果汁怎么样?

注意:

①What about you?可以表达为And you?

②有时候句型记多了,容易忘记What about/How about后边加动词ing。这里建议可以结合技巧“介词后加动词ing(这一技巧在考试中能发挥极大作用)”,about为介词,后接动词ing。
