7、ave to则表示客观多一些。回答must引出 的问句时,如果是否定的回答,不能用mustnt,而要用neednt或dont have to。如：Must we hand in our exercise books today?Yes,you must.(No,you dont have to.)2)cant在口语中代替mustnt时，表示禁止 或不准。如:You cant play football in the street.,1)表示请求、建议等,would比will委婉 客气。Would you pass me the book?2)表示意志、愿望和决心。如：I will never

10、必做的 事情实际上却做了,例9What is acceptable in one country be considered extremely rude in another.(2007珠三角五校联考),解析：句中What is acceptable in one country是主语从句，空格后的be considered是谓语；因其中的be是原形，故空格处必定是填情态动词或助动词does(由语境可知是一般现在时，主语是第三人称单数)；由句意及作者的语气可知，需填表示“可能”的情态动词may。,技巧6：若结构较完整，空格后的谓语动词是原形，特别是与上下文时态不一致或主谓不一致时，很可能是填

11、情态动词或表示强调或倒装的助动词(do,does,did等)。,may,名词性从句,在句子中起名词作用的句子叫名词从句。(Noun Clauses)名词从句的功能相当于名词词组,它在复合句中能担任主语、宾语、表语、同位语等。因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。,名词性从句 noun clause,主语从句subject clause,宾语从句object clause,表语从句predicative clause,同位语从句appositive clause,名词性从句中的连接词有:连词:that/whether/as if(thoug

16、ill sell depends on its author.That he is the best student in the class is obvious.What he needs is that book.,3.主语从句,引导主语从句的关联词有三类：1)从属连词that。如:That they were true sisters was clear from the facial resemblance between them.很明显,她们确是亲姐妹,她们的脸型很相似。2)从属连词whether。如：Whether hell come here isnt clear.他是否会来

19、象名词后面,对名词作进一步解释说明。结构:n.+连接词+从句同位语从句常用 that 引导或用连接副词when/where/why/how/whether,1)从词类上区别 同位语从句前面的名词只能是idea,fact,news,hope,belief,suggestion,proposal,word,thought,doubt,truth,possibility,promise,order problem;news等抽象名词,而定语从句的先行词可以是名词、代词、主句的一部分或是整个主句。,Homework,1、根据高考必背3500词表格，找出必修三中的高考必背词汇，并抄下2、总结情态动词用法和名词性从句,Thank you.,
