I might have killed myself. 那真的是太危險(xiǎn)了，我差點(diǎn)沒(méi)命了。You might at least have answered my letter. 你至少可以回我一封信嘛。No, he must be lying. 不，他一定在撒謊He must have mistaken my meaning. 他一定誤會(huì)了我的意思。Look at the time! We should have been at the theatre ten minutes ago. 瞧都什么時(shí)候了! 十分鐘前我們就該到戲院了。She needn’t have e in person — a letter would have been enough. 她本不必親自來(lái)——寫封信來(lái)就足夠了?，F(xiàn)結(jié)合近幾年的高考題目，對(duì)表推測(cè)的情態(tài)動(dòng)詞的用法作一歸納，希望對(duì)各位考生會(huì)有所幫助：【考例】1. Naturally, after I told her what to do, my daughter _____ go and do the opposite! A. may B. can C. must D. should (2003年普通高等學(xué)校春季招生統(tǒng)一招生考試英語(yǔ)試題（安徽卷）)【分析】Can,may,must都可用來(lái)表示”推測(cè)”，但側(cè)重點(diǎn)各有不同：May常用來(lái)指”事實(shí)上的可能性”，而can則表示一種”理論上的可能性”例如：The railways may be improved.=It is possible that the railways will be improved.
