why not Do

Why not do sth.Why not 是 Why don't you 的简单形式,所以既然有了助动词do,后面的动词应用原型.Why not do sth= How about doing sth .

记住why not后加动词原型 坑你我不是人

why not do 是祈使句,后加建议 why not to do表示疑问 有这个句子吗??? 应该是why do/does/did/didn`t sb do sth ?拓展:Why not 短语:Why is not it 为什么还是不行呢 Why will not hurt 不会疼么 Why do not school 为什么不去学校呢 例句:

why not do sth ? = why don't you do sth ?

不用啊 lz可能没明白句中一个语法 why not do sth = why don't you do sth why not在口语中主要有以下用法:1.表示同意或赞成,意为:好的;可以呀;为什么不可以呢.如:A:May I go with you? 我可以和你一起去吗?B:Why not? 可以呀.2.表

why not do =why don't +人称 +do 意思是:为什么不…… 还等于how about/what about+动词ing 意思是:干……怎么样,基本同上

区别:why not 后面直接接动词原形.why don't 后面要先接主语(即名词或代词) 才可以接动词原形.拓展:1. 举例:why not come ealier?why don't you come earlier?2.动词原形:动词原形是指使用英语时动词本身的形态,即与助动词或情态动词do, does, did, shall, will, should, would, may, might, have to, must, need, ought to等一起构成谓语的动词时,要用原形.3.英语语法:是针对英语语言进行研究后,英语语法系统地总结归纳出来的一系列语言规则.英语语法的精髓在于掌握语言的使用.

why not do=shall we do

提建议的句子:①What/ how about +doing sth.? 如:What/ How about going shopping? ②Why don't you + do sth.? 如:Why don't you go shopping? ③Why not + do sth. ? 如:Why not go shopping? ④Let's + do sth. 如: Let's go shopping ⑤Shall we/ I + do sth.? 如:Shall we/ I go shopping?

why do not do sth与why not do sth都是“为什么不……”的意思 两个句子可以互换使用,后面都跟动词原形
