1、2019-2020年高一英语情态动词用法讲与练I.情态动词+havedone的用法“情态动词+havedone”是历年高考的热点,但有些同学对这一结构不甚了解。为了便于同学们学习,现将这种结构的两种主要用法借表归纳如下。一、表示对过去情况的推测或估计所用的句式意义musthavedone肯定句一定(已经)……may/mighthavedone肯定句可能/大概(已经)……否定句可能还没有……can/couldhavedone否定句不可能(已经)……疑问句可能/也许(已经)……了吗?说明:1might/could有时并不是may/ca
2、n的过去式,而是表示一种委婉的语气或更小的可能性。2mighthavedone有时可用于疑问句中,此时might就相当于can/could。二、表示对过去所发生的事情的遗憾或责备所用的句式意义should/oughttohavedone肯定句,否定句,疑问句本来(不)应该……的might/couldhavedone肯定句本来能够/可以……的needhavedone否定句本不必要……的hadbetterhavedone肯定句,否定句,疑问句要是(没有)干了……就好了wouldratherhavedone同上本来想做……(却未做)说明
3、:1.mighthavedone有时可表示对过去发生事情的庆幸,意为“差点儿……”。如:Didn'tyouseethatcarnearlyhitme?Imighthavebeenkilled.你难道没看见那辆小车差点儿撞上了我吗?我差点就没命了。2要注意needn'thavedone与didn'tneedtodo的差别。Heneedn'thavee.他本没有必要来。(实际却来了)Hedidn'tneedtoe.他没有必要来。(实际也没来)同学们在做有关“情态动词+havedone”练习时,在掌握这一结构的两种基本用法的同时,还要仔细
