情态动词(讲义及答案)
高中英语语法讲义-情态动词
He may [might] be writing a letter. 他可能在写信。
They may [might] be going abroad next month. 他们可能在下个月出国。
③ 后接动词完成式，表示对过去可能发生的事进行推测：
另外，could还可与表示感知的动词(如see, hear, smell, taste, feel, understand等)连用表示的特定能力：
Looking down from the plane, we could see lights on the runway. 从飞机上向下看，我们可以看见机场跑道上的点点灯火。
2) 表示委婉的批评或责备：
You might have made greater progress. 你的进步本来可更大一些的。

③ 表示“差点儿就要”：
I could have died laughing. 我差点儿笑死了。
二、may与might的用法
1. 表示允许
注意以下两种情况：
(1) 表示请求允许(即请求别人允许自己做某事)，两者都可用，只是 might 表示的语气较委婉(但并不表示过去)：
May [Might] I sit here? 我可以坐在这里吗?
1) 表示过去某事可能发生而实际上却并没发生：
A lot of men died who might have been saved．很多人本来可以获救的却死了。

初一情态动词讲解及练习附答案
(could), may (might), must, have to, shall (should, will (would), dare (dared), need (needed), ought to等。
情态动词无人称和数的变化；不能单独使用，必须与其后的动词原形构成谓语一、can, could1) 表示能力（体力、知识、技能）。

Can只有一般现在时和一般过去式；而be able to则有更多的时态。

如：He was able to go to the party yesterday evening in spite of the heavy rain.2) 表示请求和允许。
-----Can I go now? ----- Yes, you can. / No, you can’t. 此时可与may互换。
在疑问句中还可用could, might代替，不是过去式，只是语气更委婉，不能用于肯定句和答语中。
---- Could I come to see you tomorrow? ---- Yes, you can. ( No, I’m afraid not. )3) 表示客观可能性（客观原因形成的能力）。
They’ve changed the timetable, so we can go by bus instead. This hall can hold 500 people at least.4) 表示推测（惊讶、怀疑、不相信的态度），用于疑问句、否定句和感叹句中。
