疑问代词:
疑问代词在句中起名词的作用,用来构成疑问句。常用的疑问代词有:
what, who, whose, whom, which, whatever, whichever, whoever, whomever
疑问代词在句中应位于谓语动词之前,没有词性和数的变化,除who之外也没有格的变化。
what, which, whose还可作限定词。
Whose books are these on the desk?
桌上的书是谁的?
What was the directional flow of U. S. territorial expansion?
美国的领土扩张是朝哪个方向的?
What events led to most of the east of the Mississippi River becoming part of the United States?
哪些事件使密西西比河以东的大部分土地归属于美国?
疑问代词在句中起名词词组的作用,用来构成疑问句。疑问代词有下列几个:
指 人: who, whom, whose
指 物: what
既可指人又可指物: which
疑问代词说明:
一、无论是做疑问代词还是限定词,which 和 what 所指的范围不同。what所指的范围是无限的,而which则指在一定的范围内,例如:
Which girls do you like best?
你喜欢哪几个姑娘?
What girls do you like best?
你喜欢什么样的姑娘?
二、Whom是who的宾格,在书面语中,它作动词宾语或介词宾语,在口语中作宾语时,可用who代替,但在介词后只能用whom, 例如:
Who(m) did you meet on the street?
你在街上遇到了谁?(作动词宾语)
Who(m) are you taking the book to?
你要把这书带给谁?(作介词宾语,置句首)
To whom did you speak on the campus?
你在校园里和谁讲话了?(作介词宾语,置介词 后,不能用who取代。)
三、疑问代词用于对介词宾语提问时,过去的文体中介词和疑问代词通常一起放在句首,现代英语中,疑问代词在句首,介词在句未,例如:
For what do most people live and work?大部分人生活和工作的目的是什么?(旧文体)
What are you looking for?你在找什么?(现代英语)
四、疑问代词还可引导名词性从句,例如:
I can't make out what he is driving at.
我不知道他用意何在。
Can you tell me whose is the blue shirt on the bed?
你能告诉我床上的蓝衬衣是谁的吗?
Much of what you say I agree with, but I cannot go all the way with you.
你说的我大部分同意,但并不完全赞同。
疑问代词用法:1. 疑问代词有who, whom, whose, which和what, 都是用来构成疑问句的:
Who is calling? 谁打电话来?
Whom do you want to speak to? 你想找谁接电话?
作主语时用who,作宾语时用whom,在口语中用who作宾语时也不少:
Who did you mean? 你指的是谁?
Who are you talking about? 你们在讲谁?
直接跟在介词后时只能用whom:
With whom did you come? 你和谁一道来的?
(口语中说“Who did you come with?时更多一些。)
2. 其他三个疑问代词可用作:
1)主语:
What’s your address? 你的地址怎样写?
Whose is better? 谁的好一些?
Which of these is yours? 哪一本是你的?
2)宾语:
What do you mean? 你是什么意思?
Which do you like better? 哪一个你更喜欢一些?
Whose have you chosen? 你选了谁的?
3)表语:
What’s her name? 她叫什么名字?
Whose is it? 这是谁的?
4)定语(这样用时有些字典标作形容词):
What time does the train leave? 这列火车什么时候离开?
Which room shall we stay in? 我们住哪间房?
Whose passport is this? 这是谁的护照?
形容词的比较级:
当两种物体之间相互比较时,我们要用形容词或副词的比较级;
当相互比较的物体是三个或三个以上时,我们就要用形容词或副词的最高级。
形容词的比较级和最高级的特殊变化规则:
一、少数单音节词前面加 more-, most- 构成比较级和最高级
tired ---- more tired , most tired
fond ----- more fond , most fond
glad ----- more glad , most glad
bored ---- more bored , most bored
pleased---- more pleased , most pleased
二、不规则变化
good /well------- better ,best
bad/badly/ill------ worse , worst
many/much-------more , most
little ------ less , least
far ---- farther, farthes / firther , furthest
old ---- older , oldest (GA)
---- older , oldest / elder , eldest (GB)
三、下列形容词和副词的比较级和最高级有两种形式
cruel----- crueler, cruelest /more cruel , most cruel
strict---- stricter , strictest /more strict , most strict
often----- oftener , oftenest / more often , most often
friendly------ friendlier , friendliest / more friendly , most friendly
clever----- cleverer, cleverest / more clever , most clever
四、下列形容词和副词没有比较级和最高(即表示”最高程度”或”绝对状态”的形容词和副词没有比较级和最高级)
empty , wrong , perfect , unique , extreme , excellent , favourite (GB)/ favorite (GA) , true , right , correct , extremely ...
形容词的比较级和最高级用法:形容词比较等级用法: 1.没有比较对象时,用原级。
I have a new computer.
2.两者比较,程度相同。
A+系动词+as+adj.+as+B.
Our school is as beautiful as theirs.
3.两者比较,程度不同。
A+系动词+not as+adj.+as+B.
The weather here is not as hot as that in the south.
4.A比B更…
The earth is bigger than the moon.
5.比较级前可以用much,even,still,far,a lot,a little,a bit,any等修饰。
Your room is much bigger than mine.
I’m a little shorter than her.
6.用比较级可以表示最高级含义:
John is stronger than any other boy in his class.=John is stronger than any of the other boys.
两者不属于同一范畴,不能用other.
Chongqing is bigger than any city in Sichuang.
7.“比较级+and+比较级” 表示“越来越…”
China is becoming more and more beautiful.
Days are getting longer and longer.
8.用the+比较级,the+比较级 表示”越…就越…”.
The busier he is, the happier he feels.
9. Which/Who+is+比较级 A或B?
A和B哪一个/谁更…?
Which is better,this one or that one?
最高级用法: 表示三者或三者以上的人或物的比较,一个在某方面超过其他两个或多个时,用最高级,结构是
主语+系动词+the+形容词最高级+of/in短语。
This story is the most interesting of the three.
1. one of the+形容词最高级+名词复数
它的意思是最…之一。
English is one of the most important languages in the world.
2. which/who…+is+形容词最高级

3.最高级前可以用序数词

一般疑问句:
是疑问句的一种。通常用yes,no来回答的疑问句叫做一般疑问句。口语中若无特殊含义,句末用升调。
其结构是:系动词be/助动词/情态动词+主语+其他成分?
通常回答为:
肯定:Yes+主语+提问的助动词
否定:No+主语+提问的助动词+not
例如:
Are you from Japan? Yes, I am./No, I'm not.
Do you live near your school? Yes, I do./No, I don't.
Can you speak French? Yes, I can./No, I can't.
一般疑问句的特性:
1.将陈述句变为一般疑问句时,如句中有be 动词(am/ is/ are)时,可直接将它们提至主语前。
如主语为第一人称,应将其改为第二人称。如:
I'm in Class 2Grade 1. →Are you in Class 2Grade 1﹖
We're watching TV. →Are you watching TV﹖
2.陈述句中有情态动词(can、may、must …)时,也可直接将它们提至主语前,即可成为一般疑问句。如:
He can swim now. →Can he swim now﹖
The children may come with us. → May the children come with us﹖
3.陈述句中只有一个实义动词作谓语且其时态为一般现在时,变为一般疑问句时要在句首加do或does主语后的实义动词用原形。如:
I like these animals. →Do you like these animals﹖
She wants to go to the movies. → Does she want to go to the movies﹖
4.一般疑问句一般读升调(↑)
5.一般疑问句有时不用yes或 no 回答。如:
Are they in town now﹖
I think so.
May I sit here﹖
Certainly.
Does he like soccer﹖
Sorry I don't know.
6. 一般疑问句的第一单词总是虚词,读的时候要读轻声。
陈述句变为一般疑问句技巧:
根据一般疑问句不同的家族,可以用不同的方法将陈述句变为相应的一般疑问句。
1、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Imy minesweourours等。第一人称分别改为相应的第二人称youyour yours等;
三问号:句末的句号改为问号。如:
Eg. I am an English teacher. → Are you an English teacher?
Eg. We can speak English fluently. → Can you speak English fluently?
2、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Do或Does;
二改:1、把谓语动词改为原形;2、改换主语称谓(同第一家组);
三问号:句末的句号改为问号。
Eg. We read English every morning. → Do you read English every morning?
Eg. Tom’s father listens to English on the radio every evening. →Does Tom’s father listen to English on the radio 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,do 或does句首用。
