在英语中是Would you please not do sth.还是 would please don't do sth

问题描述:

在英语中是Would you please not do sth.还是 would please don't do sth
如果是not do sth 为什么不要加一个助动词 ,有没有那个交际用语后面是用don't do sth的?

是Would you please not do sth.因为would是情态动词,后面跟动词原形.所以不要加助动词DO.
有don't you do sth.但好像不是交际用语吧..是反问句.don't you go?你不走吗?
交际用语一般用why not do sth.或 why don't you go shopping with me 这样的句子
