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。
