I can tell by the way your mouth is.

题目

I can tell by the way your mouth is.
A:I can tell by the way your mouth is.
B:I can tell by your mouth.
①A和B是否都是正确表达?
②A和B表达的意思是否完全相同?
③请从语法结构上分析一下A句

答案

两句在语法上都没有问题,但A不符合逻辑,它的意思是：我可以通过你嘴(怎么?)看出来.B 的意思比较明确,即：我可以通过你的嘴看出来.A句可改为:I can tell by the way your mouth is moving.这样,句法不变,但意思明确,...
