The Uniqueness of Finger-prints（指纹的唯一性）
难度：＊＊＊＊词数：266 标准时间：6分钟完成时间：______正确数：______ Every human being has a unique①arrangement of the skin on his fingers and this arrangement is unchangeable. 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’s
B. is valuable to himself only
C. is like that of others with the same type of blood
D. 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 partly
B. be replaced by a different one
C. be the same when the wound is recovered
D. become ugly
( ) 3. Some criminals remove their own finger-prints by ________.
A. using printer’s ink
B. injuring the inner skin
C. damaging the outer skin
D. damaging the colour
( ) 4. Finger-prints have often been used as a method of solving criminal case because it ________.
A. is complicated but reliable
B. is simple and not expensive
C. is expensive but easy to do
D. can bring a lot of money
情态动词表推测用法总结及专项练习
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”。如： You could have helped him. 你本来应该帮助他的。 ③表示“差点儿就要”。如： I could have died laughing. 我差点儿笑死了。 2. may / might用于表推测的用法 表示推测，两者都可用，只是might 比may 语气更不确定，表示的可能性更小。 (1) 在句型使用方面：两者均可用于肯定句和否定句，但用于疑问句时，may通常不用于句首，但可用于疑问句的句中（如特殊疑问句等），而might尽管可以用于疑问句的句首，但不算普通，通常会改用其他句式（如用could等）。如： He may [might] know the answer. 他可能知道答案。

情态动词表推测用法总结(整理稿)
情态动词表推测用法总结 （一）情态动词表推测 能用于表推测的情态动词： 英语情态动词表推测的时态构成 （1）语气部分：（以下情态动词语气由强至弱） 肯定句：must、may、might（=could） 否定句：can’t（=couldn’t）、mayn’t、mightn’t 疑问句：can、could（语气更加委婉不确定） （2）时态部分： 一般现在或一般将来时间的推测：情态动词+be；情态动词+v. 对过去时间的推测：情态动词+have done 对正在进行的时态的推测：情态动词+be doing （二）表许可、请求 1、 can, could 2、may, might 3、must 4、shall 5、will, would 1. can, could 1) 用在疑问句中，表示一般的请求。两者不同在于：用could 要比用can更加委婉，特别是没有把握得到允许时。 Can I go with you? 我能和你一起去吗？Could I ask you something? 我能问你一个问题吗？ 2) 用在陈述句中，表示许可：You can leave when you finish your work. 做完事情后你才可以走。 2. may, might 1) may用在疑问句中，也表示一般的请求。同can相比，may比较正式，常常表示尊敬之意。并且，may在疑问句中常用于第一人称，很少有May you…/they…这样的句型。Might比较少用在疑问句中，它表示请求的时候常用陈述句。 May I make a suggestion? 我可以提个建议？ 2) 用在陈述句中，表示许可，此时与can, could相近。 You may have a rest before we set out again. 我们再次出发之前你可以先休息一下。 3. must 1) 表示说话人“不许”和“禁止”某人做某事，有很强的劝告语气。 Cars must not be parked here.此地不准停车。 2) Must的一般疑问句的回答有两种，表示肯定，用Yes, you must. 表示否定，用No, you needn’t.

情态动词归纳及专项练习题
情态动词归纳及专项练习题 一、单项选择情态动词 1．If we had paid enough attention to the issue of the heavily-overloaded vehicles, the tragedy of the collapse of an overpass in Wuxi _____ avoided. A．should B．could be C．should have been D．could have been 【答案】D 【解析】 【详解】 考查情态动词用法。句意：如果我们对超载车辆问题给予足够的重视，就可以避免无锡立交桥垮塌的悲剧。本句为“情态动词+have done”结构，结合句意表示“本来可以；本来能够”应用could have done结构，且主语与谓语动词avoid构成被动关系，故应用be done形式。故选D。 【点睛】 情态动词+have done的结构和用法有以下几种： 一、must have done sth.“一定做了某事”。表示对过去事情的较有把握的推测，这时只能用在肯定句中，“肯定/必须已经干过……”，在否定句和疑问句中用can’t或co uldn’t或can/ could，例如： 1.From what you said, she must have told you all about it. 从你的话看，她一定告诉了你所有的事情。 二、can/could have done sth.本来能够做某事，而实际上未做； 1.But we could have done it all so much better. 但是，我们本可以把这一切做得更好。 三、can't/couldn't have done sth.不可能做过某事； 1. We could't have done it without you. 没有你我们办不成这事。 四、ought to/should have done sth.过去本应该做某事而实际上并没有做。 You should have done it when you first saw them blooming this spring. 你应该在今年春天第一次看到它们盛开的时候就挖一些的。 2.Even if it’s something you should have done earlier in the wee k or missed a detail on. 甚至你在一个星期前的就提早完成了一件事或者忽略了一个小细节。 2．—I don’t really like Janes. Why did you invite him? —Don’t worry. He come. He said he was’t certain what his plans were. A．must not B．need not C．would not D．might not 【答案】D 【解析】 考察情态动词，题干中的he wasn’t certain说明他可能不来，可能来，因此使用不完全否定，might not。 3．--- Oh, my God! I just missed the last bus back home.
情态动词表猜测的用法
情态动词表猜测的用法 情态动词must,can,could,should,may,might 等可以用在句中表示猜测。 1.“情态动词+动词原形”表示对现在或将来情况的猜测 I don’t know where she is. She may be in Wuhan. 2.“情态动词+进行式”表示对现在或将来正在进行的情况的猜测 At this moment, our teacher must be correcting our exam papers. 3.“情态动词+完成式”表示对过去情况的猜测 You must have been caught in the rain on your way home yesterday. 4.“情态动词+完成进行式”表示对过去正在进行的情况的猜测 Your mother must have been looking for you. 5.推测的否定形式用can’t/couldn’t，may not/might not表示
Mike can’t have found his car, for he came to work by bus this morning. 6.句子中含有表示猜测的情态动词时，其反 意疑问句的构成不能再用原句中的情态动词，而应根据原句在去掉情态动词的情况下的主谓关系来确定其反问形式。 ①The man in the white clothes must be a doctor, isn’t he? ②She must have seen the film before, hasn’t she? ③He must have an uncle abroad, doesn’t he? ④You must have met Uncle Wang in the shop yesterday, didn’t you? 7.在表示“猜测”方面的区别 情态动词must,can,could,should,may,might 都可以用于表示“猜测”（注意：could, might 表示推测时不表示时态, 其推测的程度不如can, may）。实际上，“猜测”与“可能性”在逻辑上是有必然联系的。如果认为没有某种可能性，人们就不会作出某些猜测。因此，请注意六个情态动词之间的区别与它们各

最新情态动词表推测的讲解及练习题
九年级英语表推测语气的讲解与练习 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be e.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 done e.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。 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）他准是个工人，是吗？ It must have rained last night, didn’t it? （过去）昨晚一定下雨了，是不是？

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. 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?
