高中语法情态动词及强化练习Word版

1、情态动词记忆口诀: 情态动词两要点;动词原形跟后面,说话语气较委婉,can表"能力"may"许可",must"责任"或"义务",否定回答"needn't"换;should"应该",would"愿",have to "被迫"表客观. 注释:对must构成的一般疑问句作否定回答只能用needn't.情态动词有can (could), may (might), must, have to, shall (should, wil

2、l (would), dare (dared), need (needed), ought to等。 情态动词无人称和数的变化；不能单独使用，必须与其后的动词原形构成谓语 一、 can, could 1) 表示能力（体力、知识、技能）。 Can you lift this heavy box?（体力） Mary can speak three languages.（知识） Can you skate?（技能） 此时可用be able to代替。Can只有一般现在时和一般过去式；而be able to则有更多的时态。 Ill not be able to come this afternoon.

3、 当表示“经过努力才得以做成功某事”时应用be able to，不能用Can。如： He was able to go to the party yesterday evening in spite of the heavy rain. 2) 表示请求和允许。 -Can I go now? - Yes, you can. / No, you cant. 此时可与may互换。在疑问句中还可用could, might代替，不是过去式，只是语气更委婉，不能用于肯定句和答语中。 - Could I come to see you tomorrow? - Yes, you can. ( No, Im a

4、fraid not. ) 3) 表示客观可能性（客观原因形成的能力）。 Theyve changed the timetable, so we can go by bus instead. This hall can hold 500 people at least. 4) 表示推测（惊讶、怀疑、不相信的态度），用于疑问句、否定句和感叹句中。 Can this be true? This cant be done by him. How can this be true? 二、 may, might 1) 表示请求和允许。might比 may语气更委婉，而不是过去式。否定回答时可用cant 或

5、mustnt，表示“不可以，禁止”。 -Might/ May I smoke in this room? - No, you mustnt. - May/Might I take this book out of the room? - Yes, you can. (No, you cant / mustnt. ) 用May I.？征徇对方许可时比较正式和客气，而用Can I.？在口语中更常见。 2）用于祈使句，表示祝愿。 1 / 10May you succeed! 3) 表示推测、可能性（不用于疑问句）。 might不是过去式，它所表示的可能性比may小。 1He may /might b

6、e very busy now. 2Your mother may /might not know the truth. 三、 must, have to 1) 表示必须、必要。 You must come here on time. 在回答引出的问句时，如果是否定的，不能用mustnt（禁止，不准），而用neednt, dont have to（不必）. - Must we hand in our exercise books today? - Yes, you must. - No, you dont have to / you neednt. 2) must是说话人的主观看法， 而hav

7、e to则强调客观需要。Must只有一般现在时， have to 有更多的时态形式。 1 His play isnt interesting, I really must go now. 2 I had to work when I was your age. 3) 表示推测、可能性（只用于肯定的陈述句） 1 Youre Toms good friend, so you must know what he likes best. 2 Your mother must be waiting for you now. 3. The road is wet. It must have rained

8、last night. 马路湿了，昨晚一定下雨了。（must加完成式，说明对过去事物的推测，表示“一定”或“准是”的意思。） 四、need need 作情态动词用时, 常用于疑问句、否定句。在肯定句中一般用must, have to, ought to, should代替。 1You neednt come so early. 2. - Need I finish the work today? - Yes, you must. / No, you neednt. 3) need作实义动词用时， 有人称、时态和数的变化。1.The house needs to be painted.

9、2. The house needs painting.3. He needs to finish his homework today. 五、 shall1) shall 用于第一人称，征求对方的意见。 What shall we do this evening? 2) shall 用于第二、三人称，表示说话人给对方的命令、警告、允诺或威胁。 1. You shall fail if you dont work hard.(警告) 2. He shall have the book when I finish it.(允诺) 3. He shall be punished.(威胁) 六、 w

10、ill, would 1) 表示请求、建议等，would更委婉。 Will / Would you pass me the ball, please? 2) 表示意志、愿望和决心。 1. I will never do that again. 2. They asked him if he would go abroad. 3) would表示过去反复发生的动作或某种倾向。would表示过去习惯时比used to正式，且没有“现已无此习惯”的含义。 1. During the vacation, he would visit me every other day. 2. The wound w

11、ould not heal. 4) 表示估计和猜想。 It would be about ten oclock when she left home. 七、 should, ought to 1) should, ought to表示“应该”，ought to表示义务或责任，比should语气重。 1. I should help her because she is in trouble. 2. You ought to take care of the baby. 2) 表示劝告、建议和命令。should, ought to可通用，但在疑问句中常用should。 1. You should

12、 / ought to go to class right away. 2. Should I open the window? 3) 表示推测 should , ought to (客观推测), must(主观推测)。 1.He must be home by now. (断定他已到家) 2.He ought to/should be home by now.(不太肯定) 3.
