Why not和 Why don't的区别:

1、两个句子结构不同:why don't + 主语 + 动词;why not一定要直接跟动词,动词前不能有其他成分
2、why don't 结构可以有时态的变化,比如变为过去why didn't,完成式 why haven't 等,why not没有时态变化

3、why not可以独立成句,而why don't不可以。

扩展资料:

这两个句式,在表达"建议"时,是一样的意思.既"(你)为什么不做.....?",或"(你)应该做.....".如:

1、Why don't you turn to the reference book?

2、Why not turn to the reference book?

"(你)为什么不看参考书呢?"也就是"你应该看一下参考书".

但是Why don't you do还可以作为一个疑问句使用,提出疑问.如:

Why didn't you see the football match?

"你为什么没有看这场足球赛?"

回答3:

Why not 和 Why didn't 两句有较大的区别。虽然他们都可以翻译成“你为什么不.......呢?”但Why not主要是表达一种建议,推荐对方去做not后面跟着的动作,而Why didn't则是有惋惜甚至责怪别人没有做某件事的意思了。

Why not 和 Why didn't 的区别主要表现在:
从时态上看,why not 一般现在时,表示现在还没发生的事情,还有改变的机会。而why didn't是过去时态,已成定局了。
从含义上看,why not 和 why don't you 是近义句,都表达提议做某事。而Why didn't只是为什么当初没有做某事。

Why not 和 Why didn't 的用法如下:
Why not
1. Why not stay for a cup of tea?
为何不留下喝杯茶呢?
2. Why not let her do as she likes?
为什么不让她想怎么做就怎么做呢?
3. Why not just wait and see what happens?
何不静观其结果呢?
Why didn't
1. Why didn't you try your best to get on the subway?
为什么你没有尽力赶上地铁?
2. Why didn't you come yesterday?
你昨天为什么没来?

回答5:

个人觉得可以看作一个是固定用法一个是特殊疑问句

why don't you...可以看成特殊疑问词加一般疑问句构成特殊疑问句
why not是固定用法,直接加do sth.
句意没有什么区别 都可以表示建议:为什么不?
