前文中,我明白到,might, may, could, can, will, would, should, ought to, must等9个神态抢沙,理当表现也许性理念,第四理当接抢沙的基本症状表现、经常体症状表现和实现体症状表现。诚然,“神态抢沙+实现体”除具备也许性寄义,还理当表现悬拟理念。实际而言:

1)must + have done:还是用在绝对句,表现也许,意为“绝对(开始了)……”。

You must have finished the work. 你绝对开始了实现办事了。

2)can + have done:还是用在反悔句或疑问句,表现也许,意为“大概(开始了)……”。

He can’t have left so soon. 他不大概走得如此早。

3)could + have done:可还是用在绝对句、反悔句或疑问句,表现也许、非议或难的是等,意为“大概……”、“原理当……”、“原理当……”等。

You could have finished it, but you failed. 你本理当实现,但你失败了。

4)should [ought to] + have done:可还是用在绝对句、反悔句或疑问句,表现非议或难的是等,意为“原理当……”。

You should have helped me, but you just sat and watched there.

你本理当帮学习用的,但你可在那坐着看。

5)need + have done:还是用在反悔句或疑问句,还是用在反悔时意为“原无须”,还是用在疑问句时意为“有随机组合……吗”。

You needn’t have helped me because I could make it.

你本没随机组合帮学习用的,我旁人理当做到。

6)may + have done:还是用在绝对句或反悔句,表现也许,意为“大概(开始了)……”。

She may have seen this film. 她大概开始了明白这部电影了。

7)might + have done:还是用在绝对句或反悔句,表现也许,意为“大概(开始了)……(现如今might可换为 may);

She may/ might have seen this film. 她大概开始了明白这部电影了。

除了这样还理当表现对方玩家的身上大概发作的事事后未发作,意为“原会……”(现如今 might不可以换为 may)。

Tom might have given you more help, even though he was busy.

即使汤姆很忙,他或者也就多给你大多数互利。
