why don't you do,还有其他句型吗?!?》《 why not 同义词是 why don't you 还是 why don't you do why don't you do=why not doing Why don't you 有没有过去时?比如说Why didn t you...麻烦举一下例子.还有可不可以写成why do not you.. 为什么是 Why don,t you like koalas 不是 Why do you don,t like koalas? Do you understand?That don't you why say是什么意思 You don't kown me why do you join me? why don't you 请问：这两种说法有什么区别?一个是Why don't you do sth.一个是Why do you not to do sth.还有How could you not to do 和 How couldn't you do Why do you just don't understand me? why do you don't know?语法哪里有问题? why not后加do还是to do?why don‘t you 后面呢? Why not do sth.=Why don't you do sth.=什么? why not do sth.=why don't you do sth.还等于什么 why do you say like I don't understand why do you say like thiswhy do you say like this Do /don`t you think that.would you consider.why/ why not. why don't you?可以说缩写成why do not you 这两句英语语法正确吗 why don't you know either?why do you know too?
