【知识讲解】
知识点1-------- 一般疑问句
问:什么是一般疑问句?
答:能用yes / n(或相当于yes / n)回答的问句叫一般疑问句。
二、一般疑问句的结构 一般疑问句有两个家族。
第一家族为含be动词或情态动词的一般疑问句,
其结构为: be + 主语 + 其它部分?
情态动词 + 主语 + 动词原形 + 其它部分?
肯定回答用“Yes,主语+be\情态动词.”,否定回答用“N,主语+be\情态动词+nt.”。
be或情态动词和nt可用缩写形式,主要有isn’t,aren’t,wasn’t,weren’t,can’t,mustn’t,needn’t等。
eg1. 问句: Is this yur English bk? 肯答: Yes,it is. 否答: N,it isn`t.
eg2. 问句: Are these yur English bks? 肯答: Yes,they are. 否答: N,they aren’t
另一家族为含行为动词(或称为实义动词)的一般疑问句,其结构为: 助动词 + 主语 + 动词原形 + 其它?
肯定回答用“Yes, 主语+ d\des.”,否定回答用“N, 主语+d\des nt.”。助动词也常用缩写形式,主要有dn’t,desn’t,didn’t等。 eg3. 问句: D yur parents like English? 肯答: Yes,they d. 否答: N,they dn’t.
如何将陈述句变为一般疑问句
第一家族:含be动词或情态动词的句子
秘诀:一调二改三问号
一调:即把句中的be或情态动词调到主语前;
二改:改换主语称谓,即将句中的主语I\my \mine\we\ur\urs等第一人称分别改为相应的第二人称yu\yur\ yurs等;
三问号:句末的句号改为问号。如:
. I am an English teacher. → Are yu an English teacher?
. We can speak English fluently. → Can yu speak English fluently?
第二家族:含行为动词(或称为实义动词)的句子
秘诀:一加二改三问号
一加:即在句首加助动词D或Des;
二改:1、把谓语动词改为原形;改换主语称谓(同第一家组);
三问号:句末的句号改为问号。
. We read English every mrning. → D yu read English every mrning?
. Tm’s father listens t English n the radi every evening. →
Des Tm’s father listen t English n the radi every evening?
特别注意:对于第二家族一定要注意动词的还原,因为时态与数的变化已经体现在助动词上了。
3、 加强记忆口诀:
“肯变一,并不难,can 或be提在前;
谓语若为行为动,d 或des句首用。”
知识点2--------否定句(注意要和否定回答区分哦)
把肯定句改成否定句分以下情况:
句中有be动词的,在be动词后加nt;
句中有情态动词的(can ,shuld,must ,wuld),在情态动词后面加nt;
句中没有be动词和情态动词的,在动词前加dn’t或desn’t
①句中动词为原形的,加dn’t. 如: I like apples.→I dn’t like apples.
②句中动词为三单式的,加desn’t,并将三单式的动词还原成原形。 如:He likes apples.→ He desn’t like apples.
4、肯定句中的sme在否定句中应改为any,and改为r,第一人称改为第二人称。
知识点3--------对划线部分进行提问
一、注意疑问句的语序
1.对句子的主语进行提问,其语序是:疑问词+谓语+其他成分+?
She is their teacher.→Wh is their teacher?
2.对句子主语的定语进行提问,其语序是:疑问词+主语+谓语+其他成分+?
My bk is ver there.→Whse bk is ver there?
3.对表语、宾语或状语进行提问,其语序是:疑问词+一般疑问句+?
He lives in Beijing.→Where des he live?
4.对表语或宾语的定语进行提问,其语序是:疑问词+表语或宾语+一般疑问句+?
I'm lking fr my watch.→Whse watch are yu lking fr?
二、注意疑问词的选择
1.问“谁”用wh或whm。
如:Li Lei is a dctr.→Wh is a dctr?(对主语提问用wh,对宾语提问时用wh、whm均可)
2.问“谁的”,用whse。
如:This is his bk.→Whse bk is this?
3.问“地点”,用where。
如:The ball is under the bed.→Where is the ball?
4.问“原因”,用why。
如:He didn't cme because he was ill.→Why didn't he cme?
5.问“身体状况”,用hw。
如:I'm fine.→Hw are yu?
6.问“方式”,用hw。
如:He did it in that way.→Hw did he d it?
7.问“程度”,用hw+被修饰语。
如:The river is five meters wide.→Hw wide is the river?
8.问“多少”,用hw much 或hw many。
如:I have a lt f mney.→Hw much mney d yu have?
He has been t Shanghai three times.→Hw many times has he been t Shanghai?(hw many+可数名词;hw much+不可数名词)
9.问“多久”,用hw lng,hw sn。
如:He has stayed here fr ten days.→Hw lng has he stayed here?
He will be back in tw hurs.→Hw sn will he be back?(hw lng指动作或状态持续了多久;hw sn指动作或状态还有多久才发生)
10.问“动作发生频率”,用hw ften。如:
I watch TV twice every week.→Hw ften d yu watch TV?
11.问“哪个”,用which 或 what。如:
I like this amng these three.→Which d yu like amng these three?
I like English best.→What subject d yu like best?
12.问“什么”,用what。如:
There is a bk n the desk.→What's n the desk?
13.问“职业”,用what。如:
My father is a teacher.→What's yur father?
14.问“颜色”,用what clur。如:
The range is range.→What clur is the range?
15.问“星期”,用what day。如:
Tday is Friday.→What day is tday?
16.问“月、日”,用What…date。如:
Tday is July 1st.→What's the date tday?
17.问“时间”,用when 或what time。
如:I g there in the mrning.→When d yu g there?
It is fur 'clck.→What time is it?
(when既可对钟点时间提问,亦可对年、月、日等时间进行提问,what time则通常只对钟点时间进行提问)
三、【典例探究】
【例题1】:一般疑问句及特殊疑问句
句子基本是:简单陈述句,由简单陈述句转变成肯定句,否定句,疑问句。疑问句是用来提出问题。英语中有四种疑问句: 一般疑问句、特殊疑问句、选择疑问句和反意疑问句。我们现在已经接触到了前两种疑问句。后两种疑问句以后我们还会学到.
一.一般疑问句:
英语中要用 yes和n 来回答的疑问句叫一般疑问句。如:
1)Is it ht ? Yes, it is .\N, it isn’t. —— be动词引导
2)Is it a car ? Yes, it is .\N, it isn’t . —— be动词引导
3)Is this yur ruler ? Yes, it is .\N, it isn’t . —— be动词引导
4)D yu like bananas ? —— 含实义动词
Yes, I like bananas. \ N, I dn’t like bananas.
5)Can Ming hear a drill ? ——含情态动词
Yes , Ming can hear a drill.\N,Ming can’t hear a drill.
陈述句(肯定句,否定句,一般疑问句)的转变规律:
1.肯定句: 2.否定句: 3. 一般疑问句及肯否定回答
主语+be动词+…. 1) 主语+be动词+nt+…. 1)be动词+主语+…?
Yes, 主语+be动词./
N, 主语+be动词+nt.
I am a teacher. I am nt a teacher. Are yu a teacher?
--Yes, I am./ N, I am nt.
My mther is thin. My mther is nt /isn’t thin. Is yur mther thin?
--Yes, she is./ N, she isn’t.
They are insects. They are nt/aren’t insects. Are they insects?
--Yes. they are./ N, they aren’t.
2) 主语+情态动词can+… 2) 主语+情态动词can+ nt+…. 2)情态动词can+主语+…?
Yes, 主语+情态动词can/
N,主语+情态动词can+ nt
He can jump. He can nt/can’t jump. Can he jump?
--Yes,he can./ N, he can’t.
3) 主语+动词+…. 3) 主语+助动词d/des+nt 3) 助动词d/des+主语
+…. 动词原形 +….动词原形?
Yes, 主语+助动词d/des.
N, 主语+助动词d/des+nt.
He likes t eat apples. He desn’t like t eat apples. Des he like t eat apples?
Yes,he des./ N,he desn’t.
We like t eat apples. We dn’t like t eat apples. D yu like t eat apples? Yes,we d. /N,we dn’t.
二. 祈使句:表示请求、命令、建议或劝告等的句子叫祈使句,主语yu常省略。
1、肯定形式:一般以动词原形开头。 Open the dr, please.
2、否定形式:在句首谓语动词前加Dn't。 Dn't be late fr class.
三 特殊疑问句(又叫wh-questin)
用特殊疑问词来提出问题的疑问句叫作特殊疑问句。特殊疑问词一般要放在句首。常用的疑问词有what wh ,which hw 等这些词都以wh 开头(包括hw)所以也叫作wh-questin。特殊疑问句要求回答具体内容。不能用yes或n回答。结构:疑问词+一般疑问句。回答不能用yes / n(或相当于yes / n)回答的问句。答句的句式同肯定句句式:如:
What can yu see ? I can see a cat.
What can yu hear ? I can hear a bus.
What can yu d ? I can sing and dance.
What is it ? It’s a panda.
What d yu like ? I like playing ftball
Hw ld are yu ? I’m ten.
