2、.以上4句均为 和 引导的特殊疑问句，且句子的时态为 时态。（what；where；who；一般过去）【语法透析】一、一般过去时的各种句型一般过去时，分两种情况：一是be动词的一般过去时；二是行为动词的一般过去时。一般过去时：有be（was/were）无行为动词，有行为动词无be（was/were）。It was a beautiful day.是个美好的日子。Grandma cooked fish.奶奶煎鱼了。1.一变：肯定句变为否定句【技巧1】当句中含有情态动词could，would，should等时，可直接在他们后面加not构成否定句。I could get you a concert

3、ticket.我能给你一张音乐会的票。I could not/couldnt get you a concert ticket.我不能给你一张音乐会的票。【技巧2】当句中含有连系动词was/were时，可直接在它们后面加not构成否定句。I was on the Internet when you called me.你给我打电话时我正在上网I was not/wasnt on the Internet when you called me.你给我打电话时我们在上网。【技巧3】当句中谓语是除情态动词、助动词、连系动词（was/were）以外的动词时，在该动词之前加did not(didnt)，

4、动词还原为原形，构成否定句。The famous singer sang some Chinese songs.这位著名的歌手唱了几首中文歌曲。The famous singer didnt sing any Chinese songs.这位具名的歌手没有唱中文歌曲。2.二变：陈述句变为一般疑问句【技巧1】移动词语的位置。将was,were,could,would,should等移到句首。He could pack his things himself.他能自己把东西打包。Could he pack his things himself?【技巧2】添加助动词did。谓语是除情态动词、助动词、连

5、系动词（was/were）以外的动词时，在主语之前加did，动词还原。Mr. Li looked very old.李先生看起来很老。Did Mr.Li look very old?李先生看起来很老吗？3.三变：陈述句变为特殊疑问句【技巧1】确定疑问词：人who/whom，物what，地点where，时间when/what time，原因why，频率how often，长度how long，距离how far等。They gave the concert last night.他们昨晚举办了音乐会。When did they give the concert?他们何时举办了音乐会？【技巧2】辨

6、认结构形式：疑问词+情态动词/助动词/was/were+主语+其他？The accident happened near the station.那起事故是在车站附近发生的。Where did the accident happen?那是事故是在哪里发生的？二、一般过去时的判断1.当句中用到表示过去的时间状语，用过去时。这样的状语有： a.yesterday，如：yesterday morning，at five oclock yesterday. b.last，如：last week,last monthe,last year,last Sunday afternoon. c.ago，用“一

7、段时间+ago”表示“（多久）以前”，如：ten years ago,5 minutes ago,three weeks ago. d.表示过去的时间短语，如：in the 90s,on May 1st1892,in the old days(过去的日子里)，just now,the other day(前几天)，once upon a time(很久以前)，before liberation(解放前)，When I was8 years old（当我八岁时），at+一个时间点.2.根据句意确知某一动作发生在过去，用一般过去时，如：Edison invented many useful thi

8、ngs.爱迪生范明了许多有用的东西。3.有时间、让步或结果状语从句的，一般主句用一般过去时，从句也用过去时，如：The man drank some water after he got up in the morning.4.一般过去时表示过去经常或反复发生的动作，常和often，always，once a week等表示频度的时间状语连用，如：Mrs.Peter always carried an umbrella.彼得太太过去老是带着一把伞。【试题链接】Tony football every weekend when he was young.A.plays B.played C.is

9、playing D.has played（时间状语every weekend when he was young.指的是过去，故句子用一般过去时态。答案：B）5.有些句子，虽然没有表示过去确定时间的状语，但实际上时指过去发生的动作或存在的状态的话，也要用一般过去时。如：I didnt know you were in Paris.我不知道你在巴黎（因为在说话时，我已经知道你在巴黎了。这句话指的是说话者之前，所以只能用过去时态表示。实际上，这句话暗指：But now I know you are here.）【试题链接】What the noise,Bill?Sorry,I broke my g

19、一、 由What引导的感叹句 由What引导的感叹句，其结构为:1.What + a / an +adj.+可数名词单数+主语+谓语+其他成分！如：What a beautiful girl she is!多漂亮的女孩啊! What a clever boy he is! (他是个)多么聪明的男孩啊！What a lovely day it is!多好的天气啊!What an interesting story it is !多有趣的故事啊! 2.What +adj.+可数名词复数/不可数名词+主语+谓语+其他成分！如：What interesting books they are!多有趣的书

20、啊! What beautiful flowers they are! (它们是)多么漂亮的花啊！What bad weather it is!多坏的天气啊! What fine weather it is! 多好的天气啊！3.What+a/an+名词+主语+谓语+其他成分！ What+可数名词复数/不可数名词+主语+谓语+其他成分！这类句子省略了形容词：（1）当其中的名词带有形容词的意味时.如：What luck! 真幸运! What fools! 真是些笨蛋! What a surprise! 真是意想不到!（2）当进行批评时.如： What nonsense! 一派胡言! What a

21、shame! 多可耻(惜)! What a mess! 多么脏乱啊!（八册课本P16 Part1）(3) 当表示强调或夸张时. 如：Oh, what a lie! 啊，多大的谎言! What a night! 多糟糕的一个晚上！（4）当表示蔑视时.如：What a man he is! 那家伙算什么! （5）没有上下文，意思可能不确定时。如：What a day! 看这天气! (是褒是贬，视具体情况而定)注意：在口语中,what引导的这类感叹句有时常省略主语和谓语,如： What a big fish!多大的一条鱼啊 ！What a pretty girl!多秀丽的女孩啊! What a be

22、autiful bird!多么漂亮的一只鸟啊! 二、由how引导的感叹句。 由how引导的感叹句,其结构为:1.How + adj./adv.+ 主语+谓语+其他成分！如：How big the dining room is!餐厅真大啊! How lovely the girls are!这些女孩真可爱! How beautiful those flowers are!这些花真美啊! How well she dances!她跳得真好呀! How hard he studies!他学习多么努力啊! How carefully Li Yan listens!李艳听得多么认真啊!How big t

23、he listening room is!语音室真大呀! How beautiful the park is!公园多么美丽啊! How well she sings!她唱得太好了!How clever the boy is! 这个男孩多么聪明啊！ How fast he runs! 他跑得多么快啊！ 2.How + adj.+ a / an +名词+主语+谓语+其他成分！（这和what的第1个用法，是相同意义的句子，只是表达法不同而已）如：How beautiful a girl she is!多漂亮的女孩啊!How lovely a day it is!多好的天气啊!How interest

24、ing a story it is !多有趣的故事啊!3.如果句子是纯粹的“主语谓语宾语(或其他成分)”结构， 那么，变感叹句时，可在句首直接加How。如：How I want to be a doctor! 我多么想成为一名医生啊！ How she dances! 她跳得多好啊！How I wish I was a bird!我多么希望我是一只鸟啊！注意：在口语中,how引导的这类感叹句有时常省略主语和谓语,只保留感叹部分。如: How clean! 真干净! How fast!多么快啊! 三、其他形式的感叹句感叹句除用what和how引出外，还可有其他许多形式，如可用陈述句、疑问句、祈使句

25、等，有时甚至一个单词或一个短语也可用作感叹句：Stop talking！ 不要讲话了！ Isnt it a lovely day！ 天气真好！ The garden looks so lovely today！ 这花园今天真美！ Fire！ 失火了！ Very good！ 很好! There was no face showing! Hes such a nice boy! The Great Wall is a magnificent building! Isnt it snowing heavily! Wonderful! Nonsense! Happy New Year to you!

26、Cheer! 注意：陈述句用作感叹句时，句中通常有so， such， really等加强语气的词语；疑问句用作感叹句，句子多为否定疑问句形式。感叹句巧解五法（1）一找·二断·三辨·四确定： 构成感叹句的感叹词有两个：what和how，其基本结构是： 1）What名词性词组（a/an+形容词+可数名词单数；形容词+可数名词复数或不可数名词）陈述肯定式（主语+谓语+其他成分）！ 2）How形容词（或副词）陈述肯定式（主语+谓语+其他成分！ 很多初学者常常对该用what还是该用how弄不清楚。如： _cold water this is！ AHow BWhat _col

27、d it is！ AWhat BHow 如果我们采取“一找·二断·三辨·四确定”的方法很快就能确定该选哪个感叹词。“一找”即先找出句中的主语和谓语。“二断”就是将主语和主语之前的词之间断开。例如上面第一句应在water与this之间断开。“三辨”，断开后辨别断线前面的词的词性，注意是单纯的形容词还是副词，或者是由“a/an+形容词+可数名词单数”构成的名词性词组，还是由“形容词+可数名词复数”或“形容词+不可数名词”构成的名词性词组。如句中断线前的词是cold water，是“形容词+不可数名词”构成的名词性词组。（注意：如果感叹句省略了主语和谓语，那么句中就只有

28、单纯的形容词还是副词，或者是由“a/an+形容词+可数名词单数”构成的名词性词组，还是由“形容词+可数名词复数”或“形容词+不可数名词”构成的名词性词组，这样也方便辨别。）“四确定”，根据What和How引导的感叹句的基本结构，就可迅速确定是用What还是How来引导感叹句。所以第一例句就选B。用这个方法可以立即对上面第二个例句作出如下判断：_coldit is！断开线其前只有一个单纯的形容词cold，故应填How。 上面两个例句是最基本最简单的填空题形式。但只要掌握这个方法，即使再复杂的填空题也会迎刃而解。不过还要注意，如果断开后，断线前的那个中心词是单数可数名词，千万别忘了在感叹词与名词间

29、加冠词a（an）。例如： _nice present it is！ AHow BWhat CHow DWhat a用上述方法，从present与it之间断开，断线前nice present是名词性词组，且present为单数可数名词，nice又以辅音开头，故选D。 （2）“断找去添改”五步法：若把一个陈述句变为感叹句，可以采取这“五步法”。如： The picture is very beautiful 断：在陈述句中的谓语动词后将句子断开：The picture isvery beautiful 找：划出断线后的中心词是何词类。 去：中心词是形容词或副词时，要把修饰该形容词或副词的词去掉。（

30、比如本句中心词beautiful是形容词，修饰该词的是very，变时应去掉very。但须注意，线后如果是名词，名词前的修饰语是万万不能去掉的。 添：就是添上感叹词。如果线后的中心词是名词，就添What；是形容词或副词就添How。 改：将陈述句句前的大写改为小写，将变为感叹句的感叹词及其修饰的名词部分放在句首，感叹词首写字母改为大写。同时句尾的标点由陈述句的句号改为感叹句的感叹号。 据此，上句就变成了：How beautiful the picture is！ 再如：要把“He is a good student”变成感叹句，可如上法炮制：He isa good student中心词是名词stu

31、dent，a good为修饰student的修饰语，不能去掉，故变成感叹句应选感叹词what，变成：What a good student he is！ （3）一断·二加·三换位： 例：1）This is a beautiful flower· 2）This flower is beautiful “一断”：在谓语动词后将此句划断。 1）This isa beautiful flower 2）This flower isbeautiful “二加”：在第二部分前加引起感叹句的“What或How”；中心词为名词时加“What”；是形容词、副词加“How”。 1）Wh

32、at a beautiful flower 2）How beautiful “三换位”：将第一部分与第二部分对换位置。 1）What a beautiful flower this is！ 2）How beautiful this flower is！ （4）句型记忆法：因how和what的词性及其在句中的功能不同，由它们引起的感叹句句型可归纳为7种。如果记住这7种句子，做任何感叹句题都易如反掌。 1）How +形容词+ a +名词+其他成分！ 2）How+形容词或副词+其他成分！ 3）What +名词+其他成分！ 4）What +a+形容词+名词+其他成分！ 5）What + 形容词+复数名

33、词+其他成分！ 6）What + 形容词+不可数名词+其他成分！7）其他形式的感叹句例：从题前A、B、C、D所表示的词或短语中选择正确答案，完成下列各句： A=What B=What a C=What an D=How_pleasant surprise you gave me！ _good news we have got！ _good a TV set weye bought！ _unpleasant experience you had last year！ 对了，答案依次为BADC。 （5）歌诀记忆法：感叹句中what和how的选用，关键看形容词后面是否有名词。如果有，用what（a，

34、an）；如果没有，用how（至于副词，其前永远用how）。 记住下面歌诀更方便。 what，how如何选？ 先在后面把名词找， 若有名词用what， 若无名词必用how。 what，how提句首， 其它紧跟别忘了。 主谓一起挪最后, 常常可以被省掉。【基础练习】 一、将下列句子变成感叹句 1. It is quite a nice present. _ _ nice present! 2.
