典例导学
【例1】 Listen! Somebody is singing in the next room. The ______ sounds good.
A. noise B. voice C. sound D. shout
思路点拨 要能区别noise, voice, sound, shout在表示“声音”时的不同用法。
解 答 B 在表示表示“声音”时这四个词的侧重点不同。noise 人或物体制造的“噪音”，常见短语make much noise“吵闹；喧哗”；voice“嗓音”，指人的嗓音，有时也只鸟鸣的声音。常见短语 in a low/loud voice 低声/高声;sound各种“声音”，常见短语the sound of ……的声音。句意为：听！有人在隔壁房正在唱歌。声音听起来悦耳。根据句意看当然指“嗓音”。
拓展延伸 sound当名词讲，除了“声音”的含义外，还有“声速”的含义。如：Light travels faster than sound. 光速比声速快。sound还可以当动词，意为“听起来”，后面常接一个形容词。
【活学活用】1. ( ) —The ______that the wind outside makes is driving me crazy. I can’t sleep well at night.
—Quiet down. It’s no use complaining.
A. sound B. shout C. voice D. noise
【例2】—Wearing masks is a useful way to ______ virus(病毒).
—Yes, so we should wear a mask when we go out.
A. prevent B. provide C. protect D. practice
思路点拨 句意和动词辨析。Prevent用作动词，意为“阻止；阻挠”，后接名词或代词。
解 答 A 上句句意为：戴口罩是阻止病毒的一中好办法。prevent “阻止”，provide“提供”, protect“保护”，Practice“训练”, 故选A。
拓展延伸 prevent sb. from doing sth. 意为“阻止某人做某事”，其中from可以省略。prevent可用keep, stop代替。
【活学活用】2. 完成句子：我们必须阻止学生到河里或湖里游泳。
We must____________________ together in the river or in the lake. (prevent)
【例3】 The red car is Jim’s and the blue one ______ me.
A. is belonging B. belongs to C. belonged to D. is belonged to
思路点拨 belong to中的belong是不及物动词，to 为介词, 后接代词时一定要用其宾格形式。belong to 不用于进行时态，也不用于被动语态。它的主语通常是物。
解 答 B 句意：这部红色轿车是吉姆的，这部蓝色的属于我。考查belong to的用法。belong to 意为“属于”，是固定短语不用于进行时态，也不用于被动语态；排除A, D；根据连词and前的一般现在时态，故后句也应用一般现在时态。故选B。
易错分析 belong to与be
belong to 表示某物“属于”某人，后接名词或代词宾格，不能接名词性物主代词或名词所有格
be 表示“是”某人，后接名词性物主代词或名词的所有格
【活学活用】3. ( ) ― Are these CDs _______
― No, they are not mine. They belong to _______.
A. your, her B. yours, her C. you, hers D. yours, she

典例导学
【例】—The man fishing near the river ________ be my uncle, but I’m not sure.
—That ________ be him. I saw him at the store just now.
A. might, must B. might, can’t C. must, can’t D. can’t, might
思路点拨 情态动词表示推测有三种情况：1. 表示对目前事情的推测： 情态动词+do sth. 2. 表示对正在发生的事情的推测：情态动词+be doing sth. 3. 表示对过去或已经完成的事情的推测：情态动词+ have done sth.
解 答 B 句意：—在河边钓鱼的那个人可能是我叔叔，但我不能肯定。—那不可能是他。我刚才在商店里看到他了。must必须；might可能； can’t不可能。第一个空根据but I'm mot sure（但我不确定）可知，表示
推测用might。第二个空根据I saw him at the store just now可知，那不可能是他，
否定推测用can’t，故选B。
语法精讲 情态动词表示推测
一、“情态动词+动词原形”表示对现在的推测。
1、can表示推测时一般用于否定句或疑问句。
如：That man can’t be her husband she is still single.
Who is knocking at the door 　Can it be the postman
2、must表示肯定的推测，一般用于肯定句中。
如：He must be in his office now. Mr. Li must be working now, for the lights in his office are still on.
3、might 表示推测时不一定是may的过去时，只是表示其可能性较小。
如：The man may be the headmaster.
—Where is Mr. Li —He might be working in his office.
—May Mr. Li come —He might not come here.
4、Could表示推测时，语气can比要弱，说话者留有余地。
如：—Could it be an animal —It could not be, because it is not moving.
5、Should表示推测的可能性比较大，仅比must的可能性 小一点。
如：It is already 10 o’clock now they should be there.
二、情态动词表推测的三种时态
时态 用法 示例
一般现在时 对一般情况的推测 The notebook may belong to Jim, it’s on his desk.
现在进行时 表示对正在进行的动作的推测 He must / may / might / could be listening to the radio now
现在完成时 表示对过去情况的推测或已经完成的事情的推测 It must / may / might / could have rained last night .The ground is wet.
拓展延伸 情态动词+have done 的含义
情态动词+have done 表示对过去或已经完成得事情的推测，是自主招生单项选择高频考点。我们要理解和记住每类结构表达的含义，才能正确答题。
1. could+ have done”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。
2. “might+ have done”除表示对过去的推测外，还有以下重要用法：
① 表示过去某事可能发生而实际上却并没发生。如：
It was really very dangerous. I might have killed myself. 那真的是太危险了，我差
点没命了。
A lot of men died who might have been saved．很多人本来可以获救的却死了。
② 表示委婉的批评或责备。如：
You might have made greater progress. 你的进步本来可更大一些的。
3. should have done 的用法
should have done只用于谈论过去情况，主要有两个用法：一是用于推测过去已
经发生的情况，二是用于指本该发生而实际上未发生的情况。如：
You should have told me so before. 你早就应该告诉我。
4. need have done 的用法
need have done结构主要用于否定句或疑问句，一般不用于肯定句。用于否定句
时，表示本来不必做某事，但实际上却做了；用于疑问句时，用于询问某一过去动作的必要性。如：
You needn’t have hurried. 你当时实在不必那么匆忙。
