Language pratice

1. Choose the proper word or phrase to take the place of the underlined word(s) in the sentences.

①.glass=transparent 　　　　　②. think=assume　　　 ③. make clear=clarity

　④. environment=surroundings　 ⑤. obvious=apparent　　 ⑥.towards one=sideways

⑦. distinguish=tell…apart…　　 small circles=small dots　

⑧. got=obtained　　　 enough=adequate

　e.g. He must have gone to Wuhan. (肯定已经去了)

　　He may / might / could have gone to Wuhan. (可能已去了)

　　He can not / could not have gone to Wuhan. (不可能已去了)

　　Can he have gone to Wuhan? (可能去了吗？)

can(could)/may(might)/must/will等+have+done用来对过去发生的情况做出语气强

弱不同的推测。具体使用时请注意以下几点： 　　① can一般用于疑问句和否定句, 极少用于肯定句。 　　 e.g. ---Can she have gone to school? 　　 ---No, she can't have gone to school. I saw her just now. 　　② may表推测，一般不用于疑问句；疑问句中该用can, could或might。 　　 e.g. How could he have forgotten such an important thing? (不用may) 　　　Might you have met him somewhere? (不用may) 　　③ could, may, might 用于肯定句语气较弱，must用于肯定句语气很强; may, 　

might 用于否定句语气较弱，can, could 用于否定句语气很强。 　　e.g. He could/may/might have gone to school. 他可能上学去了。 　　　 He must have gone to school. 他肯定是上学去了。 　　　 He may/might not have gone to school. 他也许没去上学。 　　　He can't/couldn't have gone to school. 他肯定没去上学。 　　④ must表推测，一般不用于否定句；否定句中该用can或could。 　　 误：We mustn't have met before. 　　 正：We can't have met before. 　needn't + have + done 可用来表示“已做了多余的事”。 　　　 　e.g. There is no school today. You needn't have come. 　 could + have + done 可用来表示没做某事的“遗憾”。 　　　 e.g. She came here on foot, but she could have come by bus. 　 could / might + have + done 也可用来表示委婉的批评。 　　　 e.g. You could have come 5 minutes earlier. 　　　You might at least have written me a letter. 　 　在反意问句中，表推测的情态动词不出现在简短问句部分,取而代之的应是情态动　

词。句中有过去时间状语的，问句部分用过去时，否则，用现在完成时。 e.g. He must have been there yesterday, wasn't he? 　 　He must have been there, hasn't he? 　He can't have been there yesterday, was he? 　He can't have been there, has he?

(1)、在肯定句中，表示很有把握的推测时用must，而不太有把握时则用may, might或could,三者依次could的语气最弱。

　 e.g. You must be very tired. 你一定很累。

　　　(= I am sure that you are very tired.) ( 很有把握)

　　You may / might / could be very tired. 你可能很累吧！

　　　(=Perhaps / Maybe you are very tired.)(不太有把握)

(2)、在否定句中，can't 则表示“不可能”，语气最强，而相应地may not, might not 语气弱些，表示“可能不”。

　 　e.g. He can't be at home. 他不可能在家。(很有把握)

　　He may not / might not be at home. 他可能不在家。(不太有把握)

(3)、疑问句中，通常用can表推测。

　 e.g.　- Someone is knocking at the door.

　　　- Who can it be ? 可能是谁呢？

　　　Where can he be now? 他现在有可能在哪呢？

4. 这种结构还可表示“年龄”.“出身”“等级”等

We are of the same age. 我们年龄相同。

He was of noble birth and high rank. 他出身于高贵门庭。

Grammar
