随堂练习一
1. Did want 2. Who will 3. belongs to 4. if/whether have 5.She said sorry to Mike for taking away his paper 【解析】1.句意:李先生想给他小女儿买件漂亮的礼物。要求改成一般疑问句,根据wanted,可知疑问句的时态用一般过去时,含有实意动词的一般疑问句的构成要借助助动词did,并位于句首,首字母大写,后接动词原形,wanted的动词原形是want,故填Did,want。2.句意:当他下周去北京的时候,他会把车借给王叔叔。对Uncle Wang提问用特殊疑问词who,谁,后接一般疑问句,由原句可知,特殊疑问句的时态为一般将来时,应将助动词will提到一般疑问句的句首,故填Who;will。3.句意:我现在正在骑一辆信自行车。那辆自行车是我的。这句话的同义句句意为:我现在正在骑的这辆新自行车属于我的。belong to,属于,动词短语,be+名词性物主代词可以和belong to sb互换,描述客观现实,用一般现在时,主语是bike,名词单数,动词用三单形式,故填belongs,to。4.句意:你给花浇水了吗?请告诉我。一般疑问句变成宾语从句连接词要用if/whether,是否,宾语从句用陈述句语序。改变后的句意为:请告诉我是否你给花交浇了水。原句为现在完成时,从句的主句为祈使句,宾语从句也用现在完成时,结构为have+过去分词,故填if/whether,have。5.句意:她因拿走了麦克的纸向他道歉。词意:said说,for因为,she她,paper纸,to朝,介词;taking away拿走,sorry对不起,Mike麦克,his他的,根据所给单词和said可知用陈述句,said sorry to sb for因……向某人道歉,his paper他的纸,故填She said sorry to Mike for taking away his paper。【点睛】考查连词成句,首先翻译单词词义,确定句子的类型,其次将词义连成句子,根据句意将单词放在对应的位置上,注意调整顺序。例如,第四小题,句意:你给花浇水了吗?请告诉我。一般疑问句变成宾语从句连接词要用if/whether,是否,宾语从句用陈述句语序。改变后的句意为:请告诉我是否你给花交浇了水。原句为现在完成时,从句的主句为祈使句,宾语从句也用现在完成时,结构为have+过去分词,故填if/whether,have。

随堂练习二
6. didn’t take 7. How often 8. didn’t they 9. do favor 10. too to 11.I sent an e-mail instead of making a phone call. 【解析】6.句意:我乘坐最后一列火车回家。本题要求改为否定句,原句中took是实意动词take的过去式形式,否定句应用助动词did构成,与not缩写为didn’t;原来的过去式应变为原形take。故填didn’t take。7.句意:奥运会每四年举行一次。句中划线部分once every four years表示举办奥运会的频率,对频率提问应用疑问词How often,意为“多久一次”。8.句意:他们尽一切可能来改善情况。本题要求改为反意疑问句,原句中谓语动词tried是实意动词try的过去式形式,反意疑问句应用助动词did构成,陈述句是肯定句,反意疑问句用否定形式,故填didn’t;主语为they,故第二个空填they。9.句意:你能帮助我搬这个书柜吗?原句中help sb do sth.意为“帮助某人做某事”,同义短语为do sb. a favor doing sth.;第一个空前有情态动词can,故填原形do;第二个空填favor。10.句意:这个男孩很矮。他够不到苹果。根据原句句意以及空后…short…reach the apple可知,这里考查too…to…结构,意为“太……而不能……”,第一个too后修饰形容词或者副词;第二个to后跟动词原形。11.句意:我发送了一个电子邮件代替打电话。这句话的主语为I,谓语动词是sent,“发送”,后跟宾语an e-mail;instead of是固定短语,意为“代替……,而不是”,后面跟动名词短语making a phone call。【点睛】这个题目是句型转换,考查了否定句、同义句、特殊疑问句、反意疑问句等句式的用法。反意疑问句:1.前肯后否,前否后肯;2.有be动词用be动词的形式;有情态动词直接用情态动词;如果谓语动词为实意动词,那么用助动词do, does或did构成反意疑问句,后面加句子的主语,必须为代词,不能加名词。如第3小题,本题要求改为反意疑问句,原句中谓语动词tried是实意动词try的过去式形式,反意疑问句应用助动词did构成,陈述句是肯定句,反意疑问句用否定形式,故填didn’t;主语为they,故第二个空填they。否定句的变化规则类似,如第1小题,原句谓语动词took也是实意动词,故否定句用助动词did构成,需要特别注意将原来的过去式took变为原形take。
Complete the following sentences as required (根据所给要求完成句子。)12.Peter likes to swim every Sunday.(改为否定句)Peter__________ __________to swim every Sunday.13.It’s five minutes’ walk from my school to my home.(对划线部分提问)__________ ___________is it from your school to my home 14.Wendy is so young that she can’t drive a car.(保持句意不变)Wendy is_________young_________drive a car.15.The boy with short, blonde hair has got his own blog.(对划线部分提问)_________ __________ has got his own blog 16.Tim seldom goes to school late.(改为反义疑问句)Tim seldom goes to school late,__________ __________ 17.drive, not, police, asked, the, after, drinking, to, people(连词成句)_________________________________________________________________________
随堂练习三
12. doesn’t like 13. How far 14. too to 15. Which boy 16. does he 17.The police asked people not to drive after drinking. 【解析】12.变为否定句,在be动词/助动词/情态动词后加not,本句话对实意动词likes进行否定,用助动词,是一般现在时,且根据主语Peter可知,用doesn’t,助动词后接动词原形,故填doesn’t like。13.对five minutes’ walk进行提问,表示距离,且根据from...to...可知,用how far“多远”,且空位于句首,故填How far。14.第一句话的含义为“温迪是如此地小,以至于她不能开车”,根据第二空后drive a car可知,用too...to...太……以至于不能……,故填too和to。15.对划线部分with short, blonde hair进行提问,应问“哪一个男孩”。which哪一个,且空位于句首,故填Which boy。16.变成反意疑问句,根据“前肯后否,前否后肯”原则可知,陈述句中含有seldom,疑问句部分用肯定句,根据goes可知,用助动词,陈述句中的主语为Tim,疑问句中应该用人称代词he,故填does he。17.根据所给单词drive(驾驶), not(不要), police(警察), asked(要求), the(定冠词,特指), after(在……之后), drinking(喝酒), to(动词不定时,后接动词原形), people(人们)。可组成一句话“警察要求人们喝酒后不要开车”,故填The police asked people not to drive after drinking
