1、情态动词专项练习情态动词 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，另外情态动词没有人称和数的变化，情态动词后必须跟动词原形。考点一： can，may，must 等情态动词在陈述句中的用法：1. can 的用法：（1）.表示能力、许可、可能性。表示能力时一般译为 “能、会 ”，即有种能力，尤其是生来具备的能力，此时 may 和 must 均不可代替它。如：She can swim fast, but I can 她能游t.得很快，但我不能。 I can see with my eyes我.用眼睛看。（2）.表示许可，常在口语中。如：You can use my dict

2、ionary. 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cant译为 “不可能 ”。如：Canthe news be true?这个消息会是真的吗？Can it be our teacher?那个人有可能是我们老师吗？No, it can t be our teacher. He is on a visit to the Great Wall不可.能。咱们老师正在游览长城呢。【例题】 I think Miss Gao must be in the library. She said she would go there. No. She _bether

3、e, I have just been there.【解析】根据下文 “我刚去过那儿 ”可知，应为 “不可能 ”，cant表示推测 答案 2. could的用法：（1）.can 的过去式，意为 “能、会 ”，表示过去的能力。如： He could write poems when he was10. 他十岁时就会写诗。（2）. could 在疑问句中，表示委婉的语气，此时 could 没有过去式的意思。 如:Could you do me 你能帮我个忙吗？ Could I use your pen?我能用一下你的钢笔吗 ?Yes, you can可.以。（注意回答）3. may 的用法：（1）

4、.表示请求、许可，比can 正式，如： May I borrow your bike? 我可以借你的自行车吗？You may go home now现.在你可以回家了。【例题】 _ I borrow your MP3? Sure . Here you are. A. May B.Should C.Must D. Would【解析】在此处表示请求，意为“做 可以吗 ”。答案： A(2) .表示推测，谈论可能性，意为 “可能，或许 ”，一般用于肯定句中。 如：It may rain tomorrow .明天可能会下雨。 She may be at home她.可能在家呢 .(3) .may 的过去

5、式为 might，表示推测时。可能性低于 may。如：He is away from school. He might- 1 -be sick.他离开学校了，可能是他生病了。(4) . 表示希望、祈求、祝愿，常可译为“祝愿”。通常是用may +主+V 例如： May you havea good time.祝你过得愉快。 May you be happy!祝你幸福！ May you succeed！祝你成功！4. must 的用法：(1).must 表示主观看法，意为 “必须、一定 ”。如：You must stay here until I come back在.我回来之前你必须呆在这儿。

6、Must I hand in my homework right now?我必须现在交作业吗？（2）对 must 引导的疑问句，肯定回答为must，否定回答或 dont have to如.： Must I finishmy homework?我现在必须完成作业吗(4)must 表示有把握的推测，用于肯定句。如: The light is on, so he must be at home now灯.亮着，他现在肯定在家。注意其反意问句的构成形式：当 must 表示肯定的判断、推测时，其反意疑问句要用实际问句的助动词来构成。 如：She must have seen the film befor

7、e, hasnshe?(t注意反意疑问句的后半部分 )You must have met uncle Wang in the shop yesterday，didn t you?(注意反意疑问句的后半部分 )5. need的用法：（ 1）.need表示需要、必须， 主要用于否定句和疑问句中， ，意为 “没有必要，不必 ”。用 need提问时，肯定回答 dont have to。如：Need I stay here any longer? 我还有必要留在这儿吗？Yes, you must 是.的。 No. you neednt/don t have. to不，你不必。(2).need 还可以作实

8、义动词， 此时有人称、 数和时态的变化， 如果是人作主语后边多接动词不定式。如：I need to do it right now.我需要马上做这件事。 He needs to learn more about the girl.他需要多了解那个女孩。如果是物作主语，一般用need doing 与 need to be done这种情况下应注意两点： .主动形式的动名词 doing 具有被动的含义； .该动名词可以改为其动词不定式的被动形式而句子的意义不变。例如： . The door needs painting. = The door needs to be painted那.扇门需要油漆

9、一下。 Your car needs mending. = Your car needs to be repaired你.的车需要维修了。7. shall 的用法：shall 表示征求对方意见（多用于第一、三人称） ，如：Shall we go out for a walk?我们出去散步好吗？在英语中，我们可以用其他多种方式提出我们的建议或征求对方意见。(1).用“ Let's do.”来提出建议。如： Let's go for a walk after supper.- 2 -(2).用“ What/How about.?”来提出建议；about 后接名词或动词 ing 形式

10、。如：What about/How about a drink? What about/How about taking Tom with us?(3).用“ Why not.?”来提出建议，表示“何不” not 面后接动词原形。“ Why not.?”实际上是“ Why don't you/we.?”的简略形式。如： Why not meet at the school gate at eight? Why don't we stay here another day?(4).用“ Would you like.?”来提出建议，意思是“你想要吗 ?”Would you lik

11、e 后可接名词或不定式。如： Would you like a cup of tea? Would you like to go and see her?因此，如果我们说： “去游泳好吗 ?”英语中可有这样几种表达法：Shall we go for a swim?Let's go for a swim，shall we?What about/How about going swimming?Why not go for a swim?Would you like to go for a swim?What do you think of going for a swim?8. shou

12、ld的用法：（1）.should 意为 “应该 ”，可表示劝告、建议、义务、责任等。如：We should protect the environment.我们应该保护环境。（ 2）Should have done 表示对过去动作的责备、批评。如：You should have finished yourhomework.你应该已经完成作业了。（事实上你没有完成。）9. will 的用法：will 表示意愿、意志、打算，可用于多种人称。如：I will help you if I m free this afternoon今.天下午如果我有空，我就会帮你。注意：1、 will 在 there

13、be句型中的形式及其句式变换。由于“一般将来时”的结构可以用“ will+ 动词原形”来表示，所以 there be 句型的一般将来时的形式就是 there will be。（一定不能说 there will have）例如： There are many students in our school. There will be many students in our school. There will be a sports meeting next week一.定不能说： There will have a sports meeting next week.2、 will 与 be

14、going to do something区别：. be going to 表示近期、眼下就要发生的事情， will 表示的将来时间则较远一些，如： He is going to write a letter tonight. He will write a book one day. be going to 表示根据主观判断将来肯定发生的事情， will 表示客观上将来势必发生的事情。 He is seriously ill. He is going to die. He will be twenty years old. be going to 含有“计划，准备”的意思，而will 则没有

15、这个意思，如： She is going to lend- 3 -us her book.He will be here in half an hour. .在有条件从句的主句中， 一般不用 be going to,而多用 will, 如：If any beasts comes at you, I'llstay with you and help you.10. had better 的用法：had better意为 “最好 ”，没有人称的变化，后面接不带 to 的不定式，其否定形式为：had betternot。如：We had better go now我.们最好现在就走。 You

16、 had better not give the book to him你.最好不要把这本书给他。考点二：含有情态动词的疑问句的回答:1.对 may 引出的问句，可以有下列回答方式： Yes,you may. Yes, of course. Yes, certainly.Sure .No, you can . t2.对 must 引出的疑问句，回答方式为：Yes, must.

(I m sorryIcan, t.)All right/ OK/ With pleasure.Certainly. (No, thank you .)Yes, please.【例题】 Would you do me ass on my thanks

18、 to Lily? _.A.That s right B.With pleasure D.No trouble【解析】 A. 意为 “对了 ”，B.意为 “乐意效劳 ”, C意.为 “没关系 ” D意.为 “不费事 ”。答案： B考点三 :不同情态动词的否定意义也不同：1.（1）.can t可译为 “不会 ”，如： I can t play basketball我不.会打篮球。（2）当句子表推测时，用cant表达不可能，如： He cant be ill. He is playing chess with Tom.他不可能病了，他正和Tom 下棋呢。（3）cant还可用来回答 “ May I?

19、这”的问句。如：样May I come in ? 我可以进来吗？ No, youcan不t.，你不能。- 4 -（4）cant还可用于固定习语中。 cant help doing禁不住，情不自禁 can t wait to dosomething 迫不及待地要做如： She cant help crying她.不禁大哭起来。The children can t wait to open the box.孩子们迫不及待地想打开盒子。2. may 的否定式为 may not，译成 “可能不 ”，如： He may not be at home他.也许不在家。考点四 :情态动词的被动语态含有情态动词

20、的被动语态的结构为： 情态动词 + be + done (动词的过去分词 )。做题时要兼顾情态动词和被动语态这两个方面。 She should speak to her mother in that way她.不应该用那种方式和妈妈说话。 More and more trees must be planted in China在.中国必须种植更多的树木。Many of the stars can not be seen because they are far away from 很us多.星星我们都看不到， 因为它们离我们太远了。考点五 :情态动词表示推测的用法:一、“情态动词 +动词原形”
