高二英语情态动词推测用法练习题30题
高二英语情态动词推测用法练习题30题1.He is always smiling. He must be in a good mood.A.can beB.might beC.should beD.could be答案：must be。
“must be”表示肯定的推测，意为“一定是”。
“can be”表示理论上的可能性；“might be”表示可能性较小的推测；“should be”表示应该是；“could be”表示可能性较大，但比“must be”可能性小。
在这个句子中，“He is always smiling.”说明他一直笑，所以推测他一定心情好，用“must be”最恰当。
2.She is not in the classroom. She may be in the library.A.must beB.could beC.should beD.can't be答案：may be。
“may be”表示有可能是。
“must be”表示肯定的推测；“could be”表示可能性较大；“should be”表示应该是；“can't be”表示否定的推测。
这个句子中“She is not in the classroom.”只是说她不在教室，不确定在哪里，所以用“may be”表示可能在图书馆。
3.The boy looks very tired. He could be staying up late.A.must beB.might beC.should beD.can't be答案：could be。
“could be”表示可能性较大的推测。
“must be”表示肯定的推测；“might be”表示可能性较小；“should be”表示应该是；“can't be”表示否定的推测。
这里“The boy looks very tired.”只是看起来累，所以用“could be”表示可能熬夜了。

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。

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。
He must have a car now. （现在）他一定有辆小汽车。
He must be doing his exercises in the classroom.（正在进行）他一定在教室里做练习。
He must have finished the work.（过去发生）他一定已完成了工作。
注：must表示推测时很少用于将来的情况。
一般不用He must come tomorrow.可用It`s certain / I`m sure that he will come tomorrow.（4）在反意疑问句中，当附属部分含有表示推测意义的must时，疑问部分的助动词应与must后面的动词在非推测情况下的用法保持一致。
He must be a worker, isn`t he? （现在）他准时个工人，是吗？It must have rained last night, didn`t it? （过去）昨晚一定下雨了，是不是？You must have learned English for many years, haven`t you? （完成时）你一定学了好多年英语，是吗？2.can / could的用法（1）can表示推测“可能性”时，往往用于否定句或疑问句。
Can`t“一定不”，语气很肯定。
can在疑问句中意思是“会、可能”。
He can`t be at home. = It is impossible that he is at home. 他一定不在家。
（2）can /can`t后可接进行时/完成时，表示对现在发生的动作或过去发生的动作进行推测。
They can`t be reading in the library. 他们一定不在图书馆读书。
He can`t have gone to Shanghai for I saw him a minute ago.他不可能去了上海，我刚才还看见他。
It`s so late. Where can she have gone? 天晚了，她可能去哪儿了呢？（3）在反意疑问句中，当陈述部分含有表示推测意义的can`t时，疑问部分的助动词应与can`t后面的动词在非推测情况下的用法保持一致.He can`t be a teacher, is he? 他不是教师，是吗？She can`t have finished her homework, has she?她一定没有完成家庭作业，是不是？（4）could可用于表示某事有可能发生或可能是事实。
Don`t eat it. It could be poisonous. 不要吃它，可能有毒。
The plane could be delayed by fog. 飞机可能会因为雾晚点。
（5）could还可以用于表示客气、委婉、礼貌的请求语气。
Excuse me, could you tell me the way to the bus station?Could you help me?（6）couldn`t表示否定推测，表示某事不可能真实，或由于特定事实或环境某事肯定不会发生。
It couldn`t possibly be poison. 这不可能是毒药。
注：有时与形容词的比较级连用强调某人或某物不可能再更多地具有某种属性You couldn`t be more wrong. 你真是大错特错。
I couldn`t be happier. 我简直是幸福极了。
3.may和might的用法（1）may, might表示推测“可能性”时，意思是“可能”、“也许”，语气没有 must肯定。
He may / might be American. = It is possible that he is American.他可能是个美国人。
注：might不表示过去时态，只是语气上比may更委婉，表示的可能性更小。
（2）may, might表推测时，可以用于否定句，意思是“可能不、也许不”，但不用于疑问句。
He may / might not be at home. 他也许不在家。
（3）may, might可以推测现在正在发生的动作或过去发生的动作。
