第七讲初中英语情态动词讲解一、情态动词的概念情态动词本身有具体的词义,但也同助动词一样,需要与其他词语一起构成句子的谓语。
情态动词有四个特征:①不能单独做谓语,必须与其他动词一起构成谓语;②没有人称和数的变化;③情态动词后必须跟动词原形;④具有助动词功能。
二、情态动词的用法1. 的用法:1)表示能力,译为“能、会”,即有某种能力,尤其是生来具备的能力,此时和不可代替它。
例句:, I ’t . 她能游得很快,但我不能。
例句:I . 我用眼睛看。
2)表示许可,常在口语中。
这里可以用代替。
例句: . 你可以用我的字典。
3)表示推测,意为“可能”,常用于否定句和疑问句中,此时’t不是“不能”而是“不可能”。
例句: . 这消息是真的。
一般疑问句:→ ? 这消息是真的吗?表推测、怀疑:→ ? 这个消息会是真的吗?例句:- ? 那个人有可能是我们老师吗?- , ’t . .不可能。
咱们老师正在游览长城呢。
【例题】—I . .—. , I .A.’tB. ’tC. ’tD. ’t注意:和的区别表达“能够”的时候,两者可以互换。
但是细微的差别在于:强调与生俱来的能力,“能够”;是后天习得的能力或者经过努力、拼搏、奋斗而做成的事,“有能力做”。
例句: .他们能够与时赶到。
例句: .有了他的帮助,他们就能与时赶到这里了。
例句: .他们能够与时赶到这里。
2.的用法:1)的过去式,意为“能、会”,表示过去的能力。
例句: 10. 他十岁时就会写诗。
2)在疑问句中,表示委婉的语气,此时没有过去式的意思。
例句: a ? 你能帮我个忙吗?例句:— I ? 我能用一下你的钢笔吗?— , .可以。
(注意回答是能够)3.的用法:1)表示请求、许可,比正式例句: I ? 我可以借你的自行车吗?例句: . 现在你可以回家了。
【例题】— I 3?A. B. C. D.2)表示推测,谈论可能性,意为“可能,或许”,一般用于肯定句中。
例句: .明天可能会下雨。
中考初中语法祈使句情态动词专题讲解与练习情态动词一.情态动词can_________________ can’t_____________________May_________________ may not______________________Must______________ mustn’t_______________________二、情态动词的特点1. 情态动词无人称和数的变化,2. 情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加 "not"。
3. 个别情态动词有过去式, 过去式用来表达更客气, 委婉的语气, 时态性不强, 可用于过去,现在。
三、情态动词的用法1. can/could;can’t/couldn’t (否定)1) 表示能力, 意为“能、会”, 例如:I can speak a little English. -- Can you ride a bike?I can’t swim. -- Yes, I can. / No, I can’t.2) 表示请求或允许,多用于口语中,意为“可以、能”等You can go home now. 现在你可以回家了 -- Can I borrow your bike?You can’t stop your car here. -- Yes, you can. / No, you can’t.3) 用于否定句、疑问句中,表示猜测、怀疑或不肯定.Lucy can’t be at home now, she went to the park just now.Where can it be? I can’t find my football.【注意:】1). could 是can的过去式, 有两种用法, 一种表示过去式;一种用来表达更加客气, 委婉的语气, 时态性不强, 可用于过去,现在。
2). be able to 意为“有能力,能够做...”, 相当于can/could, 但它有人称,数和时态的变化。

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,will③具有情态动词特征:have(had,has) to,used to,ought to④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。

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 tim e.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/ough t to be here at any moment.现在七点钟了,杰克理应随时到达。
(推测)(5).Tom should 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。
