英语翻译
答案为couldn't have received my e-mail
为什么要加have呢?我的语法知识实在不好,该从哪下手补习呢?这句话根本不懂,请高手尽量解释白话点.

句义琳达不可能收到过我的邮件,不然的话,她早就回复了.
1 Linda ( )(不可能收到我的电子邮件)：对过去真实情况的推测
2 otherwise,she would have replied是虚拟语气.
otherwise等于if she had received my email,是条件状语从句
she would have replied是主句.
这是比较典型的对过去虚拟结构,从句用过去完成时,主句用would加上现在完成时
换句话说,对过去虚拟就是从句谓语had done,主句谓语would have done.
3 如果想彻底摆脱语法困扰,建议从高中语法补起.这类语法书很多,和习题搭配使用的话,
很快就能赶上来.

英语翻译Mary couldn't have received my letter,or she should have 完成时态的用法mary couldn't have received my letter,or she have rep 英语翻译Dear Sirs,I have received your e-mail from my friend Haf 短文改错 I have received your e-mail just now.Don't worry about 解析改错I have received your e-mail.Don't worried about me.I'm g 英语翻译I have note received your e-mail and hence,there was noc 英语翻译Dear Lucy,Glad to have received your e-mail.Now I am wri Dear Mary,I have received your e-mail 这个为什么不用 I had receive Have you received an e-mail message from Helen? Mary couldn't have received your letter;otherwise she___ to I have not received my pay yet.这句话为什么要用have,为什么不用don't? 英语翻译如上述问题,两个翻译中哪个是正确的,第二句中为什么要加"have",第一句中不加"have"的语法正解吗?我知道
