Must的反义疑问句(共2页).docx
精选优质文档-倾情为你奉上Must的反义疑问句:当陈述部分有情态动词must,问句有4种情况: (1)mustn't表示“禁止,不可,不必”时,附加问句通常要用must. You mustn't stop your car here,must you? 你不能把车停在这地方,知道吗? (2)must表示“有必要”时,附加问句通常要用needn't. They must finish the work today,needn't they? 他们今天要完成这项工作,是吗? (3)当must用来表示对现在的情况进行推测时,问句通常要根据must后面的动词采用相应的形式。 He must be good at English,isn't he? 他英语一定学得很好,是吗? (4)当must+have done表示对过去的情况进行推测(一般句中有明确的过去时间状语),问句要根据陈述部分谓语的情况用“didn't+主语”或“wasn't/weren't+主语”;如果强调动作的完成(一般没有明确的过去时间状语),问句要用“haven't/hasn't+主语”。 She must have read the novel last week,didn't she? 她上星期一定读了这本小说,是吗? You must have told her about it,haven't you? 你一定把这事告诉她了,是吗?need的反义疑问句:need的用法分为两种,一种是作为情态动词,一种是作为实义动词。一般而言,need作为情态动词是在否定句(有时为疑问句中),此种情况在反义疑问句中通常为need I或needn't I,而当这句话是一句肯定句是,这里的need就作为实义动词,通常为do you或者是don't you 就比如LZ说的句子 I neednt tell you the answer , need I ?这里need为情态动词,前面否定,后用need肯定 You need to buy a better dictionary , dont you ? 这里need为实义动词,前面肯定,所以后面用do的否定形式don't 说起will,我不明白LZ是什么意思,与will有关的知识点整理在这里 开头为Let's,后面一定用shall +we例:Let's go,shall we 开头为Let us,后面一定用will you例:Let us go,will you think, believe, suppose, imagine, expect等动词后接宾语从句构成的主从复合句在构成反意疑问句时,视情况不同有两种不同的构成方式。 (1.)当主句的主语为第一人称时,其后的简短问句应与从句相一致。例如: I expect our English teacher will be back this weekend, won't she/he? We suppose you have finished the project, haven't you? 值得注意的是,当这些动词后接的宾语从句的否定转移到主句时,其仍属否定句,故其后的简短问句应用肯定式,而非否定式。例如: I don't believe that he can translate this book, can he? We don't imagine the twins have arrived, have they? 此类句子的回答同"前否后肯"型反意疑问句一样,如上述后一个句子,若双胞胎已经到了,则回答为"Yes, they have.";若尚未到达,使用"No, they haven't."。 (2).当主句的主语为第二、三人称时,其后的简短问句则应与主句相一致。例如: Your sister supposes she needs no help, doesn't she? You thought they could have completed the project, didn't you? They don't believe she's an engineer, do they? She doesn't expect that we are coming so soon, does she? (3)但如果主句的时态是过去时等等,疑问句应和主句的人称时态保持一致。专心-专注-专业
