中考英语语法复习--情态动词表推测专项练习

初中英语语法之表推测情态动词用法和练习英语中有不少情态动词都可以表示推测，其语气有强有弱，表示的可能性有大有小，现将它们的用法归纳如下：1. 接近100%的可能这当然只有must才具有这么高的可能性，它的意思是“一定”“肯定”，所作出的推测几乎接近事实。

如：That hat must be Tom’s. 那帽子一定是汤姆的。

He must be coming by bus. 他一定是乘公共汽车来。

2. 很有可能表示可能性较大的情态动词主要有may, should, ought to，它们大致相当于汉语的“可能”“应该”“按理会”。

如：She should [ought to] be here soon. 她应该很快就到。

We may be buying a new house. 我们可能要买一座新房子。

3. 一般性的可能在所有表示推测的情态动词中，might和could所表示的可能性最小，由于它们的语气较委婉，较不确定，所以往往相当于汉语的“可能”“也许”“说不定”等。

如：He might be waiting for you. 他可能在等你。

She might not like the idea. 她或许会不赞成这个想法。

We could all be millionaires one day. 我们有一天可能都成为百万富翁。

4. 理论上的可能性表示理论上的可能通常是用can，且可以用于肯定句中。

如：Food poisoning can cause death. 食物中毒可导致死亡。

This kind of thing can happen every now and then. 这种事情是随时可能发生的。

New England can be very hot in September. 新英格兰有时9月份很热。

所谓理论上的可能性，就是指仅从理论上去考虑其可能性，至于实际情况如何，则不作考虑，比如说“食物中毒可导致死亡”，这只是理论上的一种推断，至于某人某次食物中毒了，他是否会死亡，则不在考虑之列，所以说，这种推测是非常“宏观”的！5. 表示对过去情况作推测如果表示对已经发生的情况作推测，不能用“情态动词+动词原形”，也不能用“情态动词的过去式+动词原形”，而是要使用“情态动词+动词完成式”。

中考情态动词表推测的讲解及练习题表推测时，英语中只使用must,may,might,may not和can't。

这五个表达的语气依次递减：must:一定（语气肯定）may：也许（不很肯定）might：或许（比may语气更弱）may not：也许不（表否定）can't：一定不（must的反义）推测现在的事情用must,may,might,may not和can't+do或bee.g.She must be at home now.The boy may play now.推测过去的事情用must,may,might,may not和can't+have donee.g.She might have been ill yesterday.He must have hold the party.情态动词must, can, could, may, might表推测的用法情态动词中的must, can, could, may, might都表推测。

其中must的可能性最大，can / could次之，may / might最小。

具体用法如下：1.must的用法（1）表示推测“可能性”时，意思是“一定、准是”，语气较肯定，较有把握。

He must be American. = It is certain that he is American. 他准是个美国人。

（2）must表推测只能用于肯定句。

如果要表示“一定不、肯定不”的意思时，应用can’t,如询问某种可能时，应用can。

He must know my address. 他肯定知道我的地址。

（一定）He can’t know my address. 他肯定不知道我的地址。

（一定不）Can he know my address? 他知道我的地址吗？（询问可能性）（3）must表示推测时，可以推测现在/正在发生的动作/过去发生的动作。

情态动词表推测用法总结及专项练习1.can / could用于表推测的用法(1) 从使用句型上看，can 通常只用于否定句或疑问句，一般不用于肯定句，而could 可用于肯定句、否定句和疑问句。

两者没有时间上的差别，只是could 比can 更委婉，更不确定。

如：It can’t [couldn’t] be true. 那不可能是真的。

What can [could] they be doing? 他们会在干什么呢?We could go there this summer. 今年夏天我们可能要去那儿。

注：can 有时也用于肯定句中表示推测，主要用于表示理论上的可能性(即从理论上看是可能的，但实际未必会发生)，或表示“有时”之意。

如：Even experienced teachers can make mistakes. 即使是有经验的教师也可能出错。

She can be very unpleasant. 她有时很令人讨厌。

(2) 从时间关系看，对现在或将来情况作推测，后接动词原形；对正在进行的情况作推测，后接be doing 结构；对过去情况作推测，后接动词完成式。

如：He could have gone home. 他可能已经回家了。

He can’t [couldn’t] have understood. 他不可能理解了。

Why does he know this? Can [Could] someone have told him about it? 他怎么知道? 会是哪个人告诉他了吗?(3) “could+完成式”除表示对过去的推测外，还有以下重要用法：①表示过去没有实现的可能性，常译为“本来可以”。

如：I could have lent you the money．Why didn’t you ask me? 我本来可以借这笔钱给你的。

你为什么不向我提出?②用来委婉地责备某人过去应该做某事而没有去做，常译为“本来应该”。

中考英语情态动词表推测单选题50题1. Look at the dark clouds in the sky. It ______ rain soon.A. mustB. canC. mayD. should答案：C。

解析：本题考查情态动词表推测在肯定句中的用法。

must表示非常肯定的推测，意为“一定”；can表示推测时通常用于否定句和疑问句；may表示可能性较小的推测，意为“可能”；should表示按道理应该。

根据句中“dark clouds”可知有下雨的可能性，但不是非常肯定，所以用may。

2. She is so excited. She ______ have got some good news.A. canB. mustC. mightD. would答案：B。

解析：这里考查情态动词表推测。

must表示有较大把握的推测，从“excited”可以推断她很可能是得到了好消息，有比较大的可能性，所以用must。

can表推测不用于肯定句这种情况；might表示可能性较弱；would不表推测。

3. The book on the table ______ belong to Tom. His name is on it.A. canC. mustD. should答案：C。

解析：这题是关于情态动词表推测在肯定句中的运用。

must用于表示肯定性很强的推测，因为书上有Tom的名字，所以几乎可以肯定这本书是Tom的，而may表示可能性相对较小的推测；can表推测多用于否定句和疑问句；should表示应该，不表这种推测。

4. He ______ be at home now. I saw him go into his house just a minute ago.A. canB. mustC. mayD. could答案：B。

解析：本题测试情态动词肯定句中的推测用法。

must 用于推测时表示很有把握的肯定推测，根据“saw him go into his house just a minute ago”可知他现在在家是非常有可能的，有很强的确定性。

Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case.The ridge structure on a person’s fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one, which bears a reproduction of the original②pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take.Finger-prints can be made very easily with printer’s ink. They can by recorded easily. With special methods, identification③can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident.When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to “develop” them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained. ( ) 1. Scientists and experts have proved that the pattern of a human being’s finger skin ________.A. is similar to his mother’sB. is valuable to himself onlyC. is like that of others with the same type of bloodD. is different from that of all others( ) 2. If your fingers are wounded by knife, fire or other means, the structure of skin will ________.A. be changed partlyB. be replaced by a different oneC. be the same when the wound is recoveredD. become ugly( ) 3. Some criminals remove their own finger-prints by ________.A. using printer’s inkB. injuring the inner skinC. damaging the outer skinD. damaging the colour( ) 4. Finger-prints have often been used as a method of solving criminal case because it ________.A. is complicated but reliableB. is simple and not expensiveC. is expensive but easy to doD. can bring a lot of money。
