初中英语中的“反意疑问句”作者:李凤琴来源:《杂文月刊·教育世界》2016年第10期反义疑问句是疑问句的一种,它对陈述部分的事实提出相反的疑问,形式上是一个省略问句,附加在陈述句后,即:陈述句+逗号+省略问句+问号。
英语中的反意疑问句是学生学习的难点和重点,也是中考的难点和重点。
它的内容多而复杂,识记困难,运用不便,解题时常觉得无从下手。
因此,为了便于学生更好地掌握运用反意疑问句的要领,我这里以“归纳法”对其进行说明,并且举例,以便学生识记与运用。
反意疑问句的规则是“前肯后否,前否后肯”,就是说若前边句子是肯定句,简短反问句就用否定形式加上人称;若前边句子是否定句,后面的简短反问句就用肯定形式加上人称。
另外,反问句是由前后两部分构成,若前句是肯定句,后面的反问句就是系动词/助动词/情态动词等+not+人称;反之,去掉not就可以了。
此外还应注意前后人称必须保持一致,名词必须换成代词。
一、含系动词的反意疑问句系动词一般包括am, is, are, was, were等。
若前边句子含系动词,那么反问句也用和前边一致的系动词。
例如:He is a worker,isn’t he?They are not teachers, are they?但也有个特殊情况,如“I am a worker”这个句子的反问句不能用成“am not I”,而是“aren’t I”。
还有“there be”句式亦需要注意,例如:There is a watch on the desk,isn’t there?There will be a meeting tomorrow,won’t there?另外还有一种情况是主语为不定代词又含有系动词的反意疑问句,通常若主语是人,反问句人称用they或he,例如:Everyone was here ,wasn’t he /weren’t they?若主语是物,则人称一律用it,例如:Everything is ready,isn’t it?二、暗含助动词的反意疑问句常见助动词的分类如下:1.一般现在时的助动词是do或does;2.一般过去时的助动词是did;3.一般将来时的助动词是will或shall;4.现在完成时的助动词是have或has。
反义疑问句用法总结一.反意疑问句的定义反意疑问句(The Disjunctive Questions )是疑问句的一种,它对陈述部分的事实提出相反的疑问,形式上是个省略句,附在陈述部分之后,并用逗号与陈述部分隔开(主语一般用相应的代词;有时这种问句并没有反意疑问句的意味,而是提出一个事实上听话人承认的问题。
所以,人们统称为附加疑问句(Tag Questions )。
附加疑问句主要是由“陈述句 + 附加疑问”构成,附加疑问部分的动词一般要与陈述部分的动词相对应,附加疑问部分的主语要与陈述部分的主语相对应,如果陈述部分的主语是名词词组,则附加疑问部分用相应的代词表示。
二.附加疑问句的类型附加疑问句的类型为:陈述句 + 反意附加疑问。
该类型又可以分为以下两种情况阐述:①当陈述句为肯定式时,附加疑问句用否定形式,即肯定的陈述句+否定的附加疑问句。
It's very hot today, isn't it ? Yes, it is . 今天天气很热,是不是?是的,很热。
That clock is slow ,isn't it? Yes, it is. 这钟是缓慢的,不是吗?是的,它是。
You want to get your TV set back , don't you ? Yes , I do. 你想您的电视机回来,不是吗?是的,我是这样想的。
②当陈述句用否定式时,附加疑问句用肯定形式,即否定的陈述句+肯定的附加疑问句。
It isn't very hot today, is it ? 今天不是很热,是吗? That clock isn't slow ,is it ? 这钟不是缓慢的,是吗?注意这一类型的附加疑问句的回答,不管问题的提法如何,若事实是肯定的,就要用yes,事实是否定的,就要用no,这与汉语不一样,应特别注意。
She isn't a teacher , is she? 她不是教师,是吗?Yes , she is. 不,她是。
(完整版)反意疑问句的用法归纳反意疑问句:由两部分构成,前一部分是对事物的陈述(即陈述句),后一部分是简短的提问(即省略的一般疑问句)。
1. 前部分肯定,后部分否定。
2. 前部分否定,后部分肯定。

语法知识:省略、倒装和插入语(人教版高三英语下册教学论文)语法知识:省略、倒装和插入语I.省略为了使讲话和行文简洁,句中某些成分有时可以省略。
省略可分为以下几种情况:(一)简单句中的省略1、省略主语(1)祈使句中的主语通常被省略。
如:(I)Beg your pardon.(请再说一遍。
--括号内为省略的词语,下同)(2)其它省略主语多限于少数现成的说法。
如:①(I)Thank you for your help.②(I)See you tomorrow.③(It)Doesn’t matter.2、省略主谓语或主谓语的一部分。
如:①(There is)No smoking.(禁止吸烟。
)②(Is there)Anything else?(还有其它事吗?)③(You come)This way,please.(请这边走。
)④(Will you)Have a smoke?(吸支烟?)⑤What(do you think)about a cup of tea?(来杯茶怎么样?)⑥Why(do you)not say hello to him?(为何不向他问好呢?)3、省略宾语(1)省略宾语的全部。
如:①---Do you know Miss Gao? -----I don’t know (her).②----Which of the two is the better choice?----Well,it’s hard to tell (it).(2)在一定的语境中,在某些动词(如want,wish,hope,like,love 等)之后,可省略作宾语的不定式短语,只保留to。
如:①-----Are you going there?-----I’d like to (go there).②He didn’t give me the chance,though he had promised to (give me the chance).如果该宾语是be动词或是动词的完成时态,则须在to之后加be 或have。
专题十一_倒装句、省略句、强调句、插入语、反意疑问句2010届高三二轮复习专题十一倒装句、省略句、强调句、插入语、反意疑问句【考纲展现】高考试题每年都要涉及此类句法知识,这些特殊的句型结构,每年单项填空题都会出现1—2道。
考纲要求对这些句型结构的往往是以测试它们中的特殊结构为主,例如倒装句中否定副词位于句首;as引导让步状语从句的倒装;省略if 的虚拟条件句等。
反义疑问句往往要求掌握前肯后否,前否后肯的基本用法以及反义疑问句的简易回答,掌握祈使句、主从复合句、表示猜测的句式的反义疑问句,把握反义疑问句前后时态和人称的一致特点。
按照考纲要求,考生应能够恰当地使用词语和强调句式对表达的内容进行强调,近几年的高考试题主要考查考生对谓语动词的强调的理解和强调句型的灵活使用,考查复合句中的强调句式;考生应掌握英语省略的一些基本原则,在行文中正确地使用省略;而近几年的高考试题主要考查定语从句、宾语从句、状语从句、简单句中和交际语境中的省略;依据不同语境能正确使用插入语,分析近几年的高考题多以考查短语的形式,在交际用语中或句中进行辨析。
【真题评析】(2009年各地高考真题汇编解析)1 Not until I came home last night ________ to bed.A. Mum did goB. did Mum goC. went MumD. Mum went【答案】B【解析】考查倒装语序的用法。
not until 位于句首时要用半倒装的句型,把助动词did提到主语Mum的前面。
所以答案为:B2. So sudden ________that the enemy had no time to escape.A. did the attackB. the attack didC. was the attackD. the attack was【答案】C【解析】本题考查倒装,so ..that.., such ..that..的句子结构中,若so, such 和与其所修饰的词置于句首,实行部分倒装,又因为sudden是形容词,作表语,所以选C。
