She must be angry. 她不朝我看,一定是生气了;He is good at English. He must know the word. 他英语好,准知道这个词;You must be Mr. Jones. 想必您就是琼斯先生吧;4. have to的基本用法:have to可视为情态动词,但它与其他情态动词在用法上稍有不同;其他情态动词没有人称和数的变化,而have to却有人称和数的变化,要视主语的不同而变化;例:I / You / We / They have to….He / She / It has to….You don’t have to….意思是“必须,不得不”;have to强调客观需要;例:Sorry, I have to leave now. 对不起,现在我得走了;I’ve got to go to a meeting. 我得去参加一个会议;Will he have to work deep into the night 他将不得不工作到深夜吗5. need的基本用法:need的基本词义是“需要”,它既可作情态动词,又可作实义动词;⑴ need用作情态动词时,只用于否定句和疑问句;它只有一种形式,后接动词原形;例:I don’t believe you need worry. 我相信你没有必要焦急;—Need we go so soon我们需要这么早就去吗— Yes, we must. / No, we needn’t.是的,必须;/不,不必;So I needn’t tell him, need I 所以我不需要告诉他,对吧请比较以下两句话的不同意思:You needn’t buy the coat. 你没有必要买那件外衣;你还没买You needn’t have bought the coat. 你没有必要买这件外衣的;而你⑵My watch needs mending/to be mended. 我的手表需要修理了;We don’t need to work today. = We needn’t work today.Does he need to go right now = Need he go right now6. had better的基本用法:had bette r常略作’d better;现代语法认为它是一个助动词,因为它后接不意思是“最好做某事;还是做某事比较好”;get some sleep. 你最好睡一会儿;You’d better not do that again. 你最好别再做那件事;What had we better do now 我们现在怎么做才好呢, should, would, might表示推测:①.must多用于肯定句中表示把握性极大的推测,意思为“一定、肯定”;如: You have worked hard all day. You must be tired. 你已辛苦工作一整天了,一定累了;The book must be his. His name is on the cover. 这本书一定是他的,封面上写着他的名字;注意 must不表推测时,在肯定句中意思为“必须强调内在的职责”,在否定句中意思为“不许、禁止”,以它开头的疑问句否定回答常用needn’t或don’t doesn’t have to;如:We must obey the traffic rules. 我们必须遵守交通规则;Cars mustn’t be parked here. 此处严禁停车;—Must we hand in the papers this week 我们必须本星期交论文吗—No, you needn’t. 不,你们不必本星期交;②. can / could多用于否定句、疑问句或间上没有差别;用can时不相信的程度更强一些,如:The man under the tree can’t be Tom人不可能是Tom,他已经去英国了;Can it be true that he was fooled by a five-year-old boy 他被一个五岁的孩子愚弄了,这能是真的吗Could this be an excuse 这会不会是个借口How can you be so careless 你怎么这样粗心③.may / might多用来表示把握性不大的推测,意思为“也许、可能”, might比;注意区分“不可能”与“可能;如:Mr. Wang may know Professor Li’s telephone number.王先生也许知道李教授的电话号码;This might be the key Tom has been looking for.这可能就是汤姆一直在找的钥匙;She may not be there today. 今天她可能不在那儿;一、典型例题中考链接1.—Who is the man over there Is it Mr. Li— No, it ______ be him.
