初中英语情态动词专项练习题

情态动词是一种本身有一定的词义，但要与动词原形及其被动语态一起使用，给谓语动词增添情态

色彩，表示说话人对有关行为或事物的态度和看法，认为其可能、应该或必要等。情态动词后面加

动词原形。

情态动词有四类：

①只做情态动词：must,can(could),may(might)……

②可做情态动词又可做实义动词：need，will

③具有情态动词特征：have(had,has) to,used to，ought to

④情态动词表猜测：一肯一否三不定（must一肯，can not一否，may，might，could，三不定。）注：mustn't代表强烈禁止 must表示主观，have to表示客观。

常用的有：can may could must have use .

情态动词无人称和数的变化，情态动词后面跟的动词须用原形，否定式构成是在情态动词后面加"not"。个别情态动词有现在式和过去式两种形式，过去式用来表达更加客气，委婉的语气，时态性

不强，可用于过去，现在或将来。情态动词属非及物动词，故没有被动语态。

情态动词表推测的用法小结

（一）情态动词表推测的三种句式

1．在肯定句中一般用must （一定），can,could（可能），might /may（也许，或许）。

e.g:(1)He must/can/may,might know the answer to this question.

他一定/可能/也许知道这个问题的答案。

(2)It is cold in the room. They must have turned off the heating.

屋里很冷，他们肯定把暖气关了。

2．否定句中用can’t / couldn’ｔ（不可能），may not/might not（可能不）。

e.g:(1)It can’t/couldn’t be the headmaster. He has gone to America.

这不可能是校长，他去美国了。

(2)He may not/might not know the scientist.

他也许不认识那位科学家。

3．疑问句中用can/could （能……？）。

e.g:(1)．Could he have finished the task?

他可能把任务完成了吗？

注：以上三种句式中情态动词的语气按程度都是依次递减的。Might,could并非may,can的过去式，而表示语气较为委婉或可能性较小。

（二）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”。

e.g:(1)．She must / may / might / could arrive before 5.

5:00前她一定/可能/也许到。

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”。

e.g:(1)．He must / may / might / could be listening to the radio now.

他一定/可能/也许正在听收音机。

(2)．He can’t ( couldn’t ) / may ( might ) not be at home at this time.

这个时候他不可能/可能不在家。

3．对过去情况的推测，用“情态动词 + have +过去分词”。

e.g:(1)．It must / may / might / could have rained last night .The ground is wet.

地湿了，昨晚肯定/可能/也许下雨了。

(2)．The door was locked. He can ( could ) not / may ( might ) not have been at home .

门锁着，他不可能/可能不在家。

注：情态动词 should /ought to表推测时，意为“想必会，理应……”但与“have +过去分词”连用时，则又可构成虚拟语气意为“本应该做某事却没做”。例如：

(4)．It’s seven o’clock. Jack should/ought to be here at any moment.

现在七点钟了，杰克理应随时到达。（推测）

（5）．Tom s hould not /ought not to have told me your secret,but he meant no harm. （虚拟）汤姆本不该告诉我你的秘密，可是他并无恶意。

can 和could 表示推测的用法

对现在或将来的推测，两者均可用，但can 通常只用于否定句或疑问句中，一般不用于肯定句，而could则可用于肯定句、否定句和疑问句；对过去的推测，应在 can,could 之后接动词的完成式，且此时can仍只用于否定句或疑问句，不用于肯定句；而could 则可用于各种句型。如：

Can [Could] this be true? 这能是真的吗

Where can [could] he have gone? 他能到哪里去了呢

She can’t [couldn’t] have left so soon. 她不可能走得这么早。

注：could后接动词的完成式，除表示对过去的推测外，还可表示过去没有实现的可能性（即某事

本来可以发生，却没发生），或委婉地责备某人过去应该做某事而没有去做（此时不用can）。如：

You could have started a little earlier. 你本可早点动身的。

You needn’t have cooked it. We could have eaten it raw. 你其实可以不煮熟（它），我们（本来）可以生吃。

can 和could 表示允许的用法

表示现在的允许时，若是请求别人允许自己做某事，两者均可用，但用could 语气更委婉；若是自己允许别人做某事，一般只用 can，而不用 could。如：

Can [Could] I come in? 我可以进来吗

“Could [Can] I use your pen? ”　“Yes,of course you can.”　“我可以借用你的钢笔吗?”“当然可以。”（不能说Yes,you could.)

表示过去的允许时，若表示过去一般性允许（即表示某人随时都可以做某事），用could；若表示在过去某一特定情况下允许进行某一特定的活动，则不用 could。如：

When I lived at home,I could watch TV whenever I wanted to. 我住在家里时，想什么时候看电影就可以什么时候看。（一般性允许）

I was allowed to see the film yesterday evening. 昨天晚上允许我去看了电影。（特定的允许，不

能用 could)

can 和could 表示能力的用法

can 表示现在的能力，could 表示过去的能力，要表示将来具备的能力通常be able to 的将来时态。其中要注意的是，could 表示过去的能力，通常只用于表示过去一般性能力，而不表示过去具体某

次特定情形下能够做某事的能力。如：

他学习很努力，所以考试能及格。

误：He studied hard and could pass the exam.

正：He studied hard and was able to pass the exam.

注：若在否定句中没有以上限制，即couldn’t 可表示过去特定情况下的能力，如可说 He studied hard but still couldn’t pass the exam.

口诀：情态动词两特点

动词原形接后面，说话语气较委婉。can "能力"may"许可"，must"责任"或"义务"。否定回答needn’ｔ换，"需要"need, dare"敢"。should"应该"，would"愿"，have to"被迫"表客观。

情态动词 一、概述 情态动词表示说话人对某一动作或状态的态度，认为“可能、应当、必要”等等，但本身意义不完全，不能单独作谓语，必须和其他动词一起构成谓语。除ought, used, have后跟不定式外，其他情态动词一律跟动词原形。情态动词主要有：can/could, may/might, must, ought to, used to, need, dare, shall/should, will/would, have to等。 二、基本用法 （一）can和could的用法 1．表示能力，可译为“能，会”。 I can swim. 我会游泳。 Emily can dance well and her mother could dance well when she was young. The cinema can seat 1,000 people. I could not read such an easy book when I was 7 years old. 2．表示允许、许可，常用在口语中。could比can语气上要客气。 --- Could I use your dictionary? 我可以用一下你的字典吗？ ---Yes, go ahead. 可以，用吧。（或Yes, you can. 但不能说Yes, you could.） Could/ Can you tell me how to get to the zoo? 劳驾，你能告诉我怎么去动物园吗？ He asked me whether he could take the book out of the reading room. 3. 表示可能（理论上或是逻辑判断上）。 The temperature can fall to–60℃,that is60℃below freezing.气温可降至—60℃，也就是零下60℃。 You mustn′t smoke while you′re walking around in the wood.You could start a fire. 在林子里走时勿吸烟，那样可能会引起火灾。 3．表示推测，可用于肯定句（can罕见）、否定句和疑问句，但更常见于疑问句或否定句。在此种用法中can和could没有时态的区别，只是表示可能性的大小，can表示推测的可能性比could大。 Can he be ill at home? 他会是生病在家吗？ Can the story be true? 这个故事会是真的吗？

情态动词 情态动词是一种本身有一定的词义，但要与动词原形及其被动语态一起使用，给谓语动词增添情态色彩，表示说话人对有关行为或事物的态度和看法，认为其可能、应该或必要等。情态动词后面加动词原形。 情态动词有四类： ①只做情态动词：must,can(could),may(might)…… ②可做情态动词又可做实义动词：need，will ③具有情态动词特征：have(had,has) to,used to，ought to ④情态动词表猜测：一肯一否三不定（must一肯，can not一否，may，might，could，三不定。） 注：mustn't代表强烈禁止 must表示主观，have to表示客观。 常用的有：can may could must have use . 情态动词无人称和数的变化，情态动词后面跟的动词须用原形，否定式构成是在情态动词后面加 "not"。个别情态动词有现在式和过去式两种形式，过去式用来表达更加客气，委婉的语气，时态性不强，可用于过去，现在或将来。情态动词属非及物动词，故没有被动语态。 情态动词表推测的用法小结 （一）情态动词表推测的三种句式 1．在肯定句中一般用must （一定），can,could（可能），might /may（也许，或许）。 e.g:(1)He must/can/may,might know the answer to this question. 他一定/可能/也许知道这个问题的答案。 (2)It is cold in the room.
