1、反义疑问句一、反义疑问句又叫附加疑问句。反义疑问句由两部分组成:前一部分是一个陈述句,后一部分是一个简短的疑问句,两部分的人称时态应保持一致。1. 陈述部分为肯定式 + 疑问部分为否定式(如果陈述部分的否定词带有否定前缀,那么,该陈述部分作肯定处理,附加疑问部分一般仍用否定形式) e.g. She was ill yesterday, wasnt she? Tom dislikes the book, doesnt he?2. 陈述部分为否定式 + 疑问部分为肯定式(陈述部分用 no, nothing, nobody, never, few, seldom, hardly, rarely, l
2、ittle等否定或半否定含义的词时,疑问部分用肯定式。)e.g. He cant ride a bike, can he? Some plants never blown (开花), do they ?二、附加疑问句(一)主语的选择1陈述部分的主语是I,疑问部分要用 arent I. Im as tall as your sister, arent I?注:当陈述部分的主语是I,而句子又用来征询对方的意见时,附加疑问句中的主语用you。如: I find English very interesting, dont you? I dont like that film, do you? 2当陈
3、述部分的主语是everybody, everyone, someone, nobody, no one, somebody等合成代词时,附加疑问句中的主语通常用they,亦可用he,如: Somebody phoned while I was out, didnt they? Everyone enjoyed the party, didnt they? Nobody wants to go there, does he? 3当陈述部分的主语是不定代词everything, nothing, anything, something时,附加疑问句中的主语一般用it,如: Everything s
4、eems all right now, doesnt it? Nothing is kept in good order, is it? Something must be done to stop pollution, isnt it? 4当陈述部分的主语是指示代词this, that或these, those时,附加疑问句中的主语分别用it和they,如: This is important, isnt it? That isnt correct, is it? These are your friends Tom and Jack, arent they? 5如果陈述部分是以代词one作
5、主语,附加疑问句中的主语在正式场合用one,非正式场合下可以用you或he,如: One cant be too careful, can one?或can you? One should do his duty, shouldnt he? 6当陈述句为there be结构时,附加疑问句中的主语也用there。如: Theres no help for it, is there? Theres something wrong, isnt there? 7当陈述部分为主从复合句时,附加疑问部分一般应与主句的主语和谓语动词保持对应关系。如: She says that I did it, does
6、nt she? I told them not everybody could do it ,didnt I? 但当陈述部分的主语是I,谓语是think, believe, suppose, expect这类动词时,附加疑问部分则往往与从句中的主语和谓语动词保持对应关系,但要注意否定的转移。 I suppose that hes serious isnt he? I dont think she cares, does she? 8当陈述部分是并列句,附加疑问句则需和就近的分句的主语和谓语一致。如: Xiao Lin has been writing letters all afternoon
7、 but he should finish them now, shouldnt he? 9在由“祈使句+附加疑问”构成的附加疑问句中,附加疑问部分的主语一般用you。如: Dont open the door, will you? Give me some cigarettes, can you? Take a rest, why dont you? 但以lets开头的祈使句,附加疑问部分用shall we;以let us开头的祈使句,如果含义是allow us,不包括听话人在内,疑问部分用will you。如: Lets have a basketball match this after
8、noon, shall we? Let us go out for a rest, will you? 10陈述句子中的主语为动词不定式短语、动名词短语或其他短语时,疑问部分的主语通常用it。如: Learning how to repair motors takes a long time, doesnt it? Between six and seven will suit you, wont it? Where to hold the meeting has not been decided, has it?(二)谓语动词的选择1当陈述部分带有情态动词must表示“必须”时,疑问部分用m
9、ustnt。如: You must work hard next term, mustnt you? I must answer the letter, mustnt I? 但若表推测这层含义时,不能用must,而要根据陈述部分的不定式结构(即must之后的动词)以及含义采用相应的动词形式。如: You must have made a mistake, havent you? They must have seen the film last week, didnt they? He must be in the library, isnt he? 2当陈述部分含有used to时,疑问部分
10、可用usednt或didnt。如: The old man used to smoke, didnt /usednt he? Tom used to live here, usednt /didnt he? 3当陈述部分带有情态动词ought to时,疑问部分用oughtnt或shouldnt。如: He ought to know the answer, oughtnt he? We ought to read this book, oughtnt/ shouldnt we? 4当陈述部分含有情态动词dare或need时,疑问部分常用 need /dare +主语。We need not d
