2017高考英语备考复习：情态动词和虚拟语气2_高考复习指南

　　(4) 其他一些表示祝愿的句型。如：

　　May you succeed！祝你成功！

　　Long live the People's Republic of China.

　　中华人民共和国万岁！

　　【误】 The streets are all dry; it mustn't have rained last night.

　　【正】 The streets are all dry; it can't have rained last night.

　　【解析】对某一事实的否定推测不能用must，而要用can't 或couldn't表示“不可能”。

　　2．【误】 I didn't see Mary at the meeting yesterday. She might be ill, I guess.

　　【正】 I didn't see Mary at the meeting yesterday. She might have been ill, I guess.

　　【解析】猜的事情发生在昨天，因此要用情态动词＋have done形式，当动词是be时，很容易忽略它的时态意义，要特别留意。

　　3．【误】 He must be very friendly at times.

　　【正】 He can be very friendly at times.

　　【解析】句意为：他有时会很友好。可知此处并非对现在的状态进行推测，而是一种理论上的可能性，因此用can。

　　4．【误】 I can't find my keys. I may/might forget them on the playground yesterday.

　　【正】 I can't find my keys. I may/might have left them on the playground yesterday.

　　【解析】表示对过去情况的推测，通常用must/may/might have done sth. 另外，表示“把……忘记在某地”应用动词leave。
