一．“ must，can/ could，may/ might + 动词原形”常用来表示对现在或将来发生情况的推测。
① must 只用于肯定句中，表示“一定、肯定”。其否定 mustn’t 表“不准、禁止、不可以”等。如：
He never takes a taxi. He must be very poor.
I thought you must like something to read，so I have brought you some books. 我想你一定喜欢看点东西，所以我带来了些书。
注意：含有 must be 的反意疑问句，常用“ is/are + 主语”。含有 must do 的反意疑问句常用“ do/ does + 主语”。
② can/ could 多用于否定句或疑问句中，偶尔用于肯定句中表示一种可能性。如： Attending a ball can be exciting.
Michael can’t be a policeman，for he’s much too short. 迈克不可能是警察，因为他太矮了。
③ may/ might 通常用于肯定或否定陈述句中。当表示某事可能发生时，可用could，may，might .如：
— Are you coming to Jeff’s party？ 你来参加杰夫的晚会吗？
— I’m not sure. I may/ might go to the concert instead. 不太确定，我有可能去参加音乐会。 二、 could/ can，may.
might 表示“请求、建议、许诺、能力”等。could/may 用于表示委婉地提出请求或允许，“给予请求”的答复用 can/may . could/might 也可以表示“许可”，语气比 can/may 委婉，表示的可能性较小。如
— Could I call you by your first name？ — Yes，you may/can. 二．宾语从句
（1）that:陈述句充当宾语从句，由that引导，that不在从句中担当成分，只起连接作用，常可省略
(2) if/whether：一般疑问句充当宾语从句时，用if/wtether引导，宾语从句的语序是陈述句语序，但在or not之前，不定式之前，介词之后只能用whether 宾语从句中常见的错误 一. 连词错误
例1:He asked ________ there was a bookshop in the street. A. that B. what C. how D. whether 错解:A;正解:D
剖析:ask 表明了宾语部分含有询问的意思。而that不能引导疑问语气的句子。 例2:Tell me ______ you will go with us or stay at home. A. if B. whether C. that D. how 错解:A;正解:B
剖析:引导宾语从句时,if和whether常可以互换,但有些情况是不能互换的?穴当从句中提出了两种选择,或从句位于介词后面,只能用whether?雪。
二. 语序错误
例1:He wanted to know_______.
A. when would the holiday begin B. that he had come back from Beijing C. which one did I like best D. how he could get to the station 错解:A/C;正解:D
剖析:宾语从句必须用陈述句语序。 例2:I wonder____.
A. who broke the window B. who the window broke
C. whose coat is this D. what is the population of China 错解:B;正解:A
剖析:B貌似陈述句语序,但在这里连接词who是从句的主语,而不是the window。 三. 结构错误
例: I don’t know________.
A. which room I can live B. which room can I live C. which room I can live in D. which room can I live in 错解:A;正解:C
剖析:如果连接词在宾语从句中充当不及物动词后介词的宾语,并被放到从句句首时,不及物动词后的介词不能少。 四. 时态错误
例1:Long, long ago, people didn’t know the earth___ round the sun. A. moving B. moved C. moves D. went 错解:B/D;正解:C
