be supposed to do sth与should have done sth 有什么区别?
be supposed to do sth与should have done sth 有什么区别?
be supposed to do sth与should have done sth 有什么区别?
should have done sth的sth比be supposed to do sth的sth更贴近现实,是客观正确该做的事
be supposed to do sth的事情只是理论上应该做的事,有可能是依照常理该做的,依照他人的命令该做的,是在某人主观观念中正确的事.
还有不解请追问
第一个是 应该做...
第二个是 本应该做什么却没有 比如 JACK FAILED THE EXAM,HE SHOULD HAVE DONE BETTER.
1、应该做某事
2、本应该做某事而没有做
