情态动词语法填空2017

【1】情态动词的基本用法（表能力）

表示“能力”的情态动词有：can，could，be able to 表示过去能力时，was/were able to表示经过一番努力后取得了成功。相当于manage to do或succeed in doing，而could没有这个含义。

Yesterday I was able to get home before the heavy rain. 昨天我在下大雨前赶到了家里。

【2】情态动词的基本用法（表必要、义务、责任）

表示“必要性”的情态动词通常有：must，should，ought to，have to ought to与should意思大体相同，但ought to语气比should重，往往表示从法律或道义上“应该”。

【3】情态动词的基本用法（表请求、允许、命令、禁止）

Shall , can , may, must, mustn’t 【4】情态动词“偏义”大本营

(1)表示过去经过努力而成功地做了某件具体的事情时，只能用was/were able to，不用could。

(2)must有一种含义，即“偏要”。

(3)shall可以用于第二、第三人称，表示说话人的允诺、命令、警告、威胁等；在法律、条约、协定等文件中可以表示义务、规定等。

(4)will可以表示意愿。will还可以表示经常性、习惯性、倾向性等，意为“经常，惯于，总是”。

(5)should表示惊异、意外等情绪，经常用于疑问句和肯定句中，多译为“竟然，居然”。

【5】情态动词表推测的用法（肯定推测与可能性推测）

1. must用于肯定句，表示较有把握的推测，意为“准是，一定”。

2．should用于肯定句中，语气次之，意为“很可能，应该”，指按常理推测。

3．can用在肯定句中，表示理论上的可能性。如：

Smoking can cause cancer. 吸烟有可能引起癌症。

4．may用在肯定句中，表示对现在把握不大的推测，意为“也许，可能”。

5．could，might也可表示推测意义，常用在过去时态中；但在某些场合下，为了使语气更缓和、更委婉，常用could，might代替can，may。如：

They saw something in the sky last night.It could/might be a UFO.昨天晚上他们看见天空中有个东西。它有可能是不明飞行物。

【6】情态动词表推测的用法（否定与疑问推测）

【否定推测】

(1)表示否定的推测时，can't/couldn't语气最强，指“不可能”，带有惊异、怀疑的感情色彩。如：

The story sounds reasonable，but it can't be true. 这个故事听起来合情合理，但不可能是真的。

(2)语气不很肯定时，常用may not或might not表否定推测，意为“可能不，也许不”。如：

He may not/might not be at home.他可能不在家。

【疑问句中的推测】

疑问句中的推测，常用can或could，意为“可能”。如：

Who can it be？Can it be Jenny? 那能是谁呢？是玛丽吗？

【7】情态动词表推测的三种时态

(1)对将来情况的推测，用“情态动词＋动词原形”。

She must arrive before 5.5：00前她一定到。

(2)对现在或一般情况的推测，用“情态动词＋be”，“情态动词＋be doing”或“情态动词＋动词原形”。

He must/may be listening to the radio now. 他一定/可能正在听收音机。

(3)

“情态动词＋have done”表过去的推测

(a)must have done“一定已经做了”，表肯定推测，否定式为can't/couldn't have done；

(b)can/could have done表示“本来能够做，却没有”，或“过去可能会”；

(c)may/might have done不用于疑问句，表示“也许……；或许已经做了……”；

(d)should/ought to have done意为“本该做了，但未做”，否定式shouldn't/ought not to have done意为“本不该做，但做了”。它们都暗含对其责备；

(e)needn't have done表示“做了本没有必要做的事”；

(f)would rather have done意为“宁愿当时做过某事”，否定式would rather not have done意为“宁愿当时没有做过某事”。它们表示后悔之意。
