请讲讲情态动词表推测的用法
must,may与might,could在表推测的时候有什么区别?自学没学明白,
must,may与might,could在表推测的时候有什么区别?自学没学明白,
表推测时,英语中只使用must,may,might,may not和can't.这五个表达的语气依次递减：
must:一定（语气肯定）
may：也许（不很肯定）
might：或许（比may语气更弱）
may not：也许不（表否定）
can't：一定不（must的反义）
推测现在的事情用must,may,might,may not和can't+do或be
e.g.She must be at home now.
The boy may play now.
推测过去的事情用must,may,might,may not和can't+have done
e.g.She might have been ill yesterday.
He must have hold the party.
注意：表推测的must,may,might,may not和can't是不可以与I think...连用.因为I think...已有推测的含义,故不能连用
