2017高考英语知识点：look,watch,see区别和用法
look, look at, see, watch 都有"看"的意思，但用法不同。以下是小编整理的2017高考英语知识点：look，watch，see的区别和用法，供同学们参考学习。
1. 从词义上看：look 通常表示主动地、有意识地“看”，侧重指看的行为;see 通常指看的客观结果，即“看见”;watch 也指有意识地看，但往往指仔细地盯着看事物的变化。如：
I looked hard but saw nothing. 我认真看，但什么也没看见。
The cat is watching the mouse. 猫儿盯着老鼠。
If you watch (look) carefully, you will see how I do it. 你要是仔细观察(看)，你就能看出我是怎样做的。
2. 从是否及物来看：
(1) look 通常为不及物动词，若需后接宾语，其后须接介词(如at, for, after 等)。如：
Look at the blackboard. 看黑板。
He is looking for his wallet. 他在找钱包。
有时 look 也用作及物动词，表示“仔细打量”。如：
He looked me up and down. 他上下打量我。
(2) see 可用作及物或不及物动词。如：
It was so dark I could hardly see (it). 太黑了，我几乎看不见(它)。
(3) watch 通常为及物动词。如：
Did you watch the tennis match? 你观看了网球赛吗?
有时也用作不及物动词。如：
A：Won't you sit down and join us in the game? 坐下来跟我们一起玩好吗?
B：No, I prefer to watch. 不，我喜欢看。
3. 从时态上看：look 和 watch 可用于进行时态(例句见上)，而 see 作为感官动词，一般不用于进行时态。
但有时表示有意识的行为(如表示“看望”、“会见”、“陪送”等)，也可用于进行时态。如：
He is seeing his friend off. 他在送朋友。
I’ll be seeing you in the evening. 咱们晚上见。
4. 从表达习惯上看：看戏、看电影、看话剧、看演出等通常用动词 see (有时也可用 watch，但不如用 see 常见);另外，看展览、看风景、看望朋友等也通常要用动词 see;看电视、看比赛等通常用动词 watch;看图片、看黑板等，通常用动词 look at。
look是强调看的动作。例：look!it is a bird.
see是强调看的结果，强调的看得见看不见。例：i can see a bird. watch用在看电视看比赛的时候。例：let's watch tv together.
look at是look的短语，look本身是不及物动词，如果它要带宾语的话，后面就必须要有一个介词，所以有look at这个短语，意思是看着某某。例：look at the blackboard,everyone
2017高考英语知识点：定语从句
关系代词有：who, whom, whose, that, which, as。
关系副词有：when, where, why, how。
关系代词和关系副词放在先行词和定语从句之间，起连接作用，同时又可做定语从句的一个成分。当关系代词做宾语时可以省略。
定语从句中的谓语动词必须在人称上和数量上和先行词保持一致。
定语从句分为限制性定语从句和非限制性定语从句。
1关系代词引导的定语从句
1) who, whom, that 这些词代替的先行词是人的名词或代词，在从句中所起作用如下：
Is he the man who/that wants to see you?
(who/that在从句中作主语)
He is the man whom/ that I saw yesterday.
(whom/that在从句中作宾语)
2) whose 用来指人或物，(只用作定语，若指物，它还可以同of which互换).
例如：
Please pass me the book whose (of which) cover is green.
3) which, that 它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等.
例如：
A prosperity which / that had never been seen before appears in the countryside.
(which / that在句中作宾语)
The package (which / that) you are carrying is about to come unwrapped.
(which / that在句中作宾语)
关系代词that和which 都可以指物，that 和Who 都可以指人，其用法区别：
不用that的情况：
a) 在引导非限定性定语从句时
(错)The tree, that is four hundred years old, is very famous here.
b) 介词后不能用
We depend on the land from which we get our food.
c) 多用who 的情况
①关系代词在从句中做主语
A friend who helps you in time of need is a real friend.
②先行词为those, people 时
Those who were either fools or unfit for their offices could not see the cloth.
③先行词为all, anyone, ones, one 指人时
One who doesn't work hard will never succeed in his work.
④在There be句型中There is a stranger who wants to see you.
⑤在被分隔的定语从句中
A new teacher will come tomorrow who will teach you German.
⑥在有两个定语从句的句子中，其一用who，其二用that,但若先行词后接两个以上的并列定语从句时，后一个必须重复前一个关系代词。
The student who was praised at the meeting is the monitor that is very modest and studies very hard.
There is a teacher who is always ready to help others and who enjoys what he does.
只能用that作为定语从句的关系代词的情况
a)在不定代词，如：anything, nothing, everything, all, much, few, any, little等作先行词时，只用that，不用which。
All that is needed is a supply of oil.
Finally, the thief handed everything that he had stolen to the police.
b)先行词有the only, the very, the just修饰时，只用that。
He is the very man that helped the girl out of the water.
c)先行词为序数词(the last)、数词、形容词最高级时，只用that。
The first English book that I read was "The Prince and the Pauper" by Mark Twin.
d)先行词既有人，又有物时。
He talked about the teachers and schools that he visited.
e)当主句是以who 或which 开始的特殊疑问句时，用that 以避免重复。
Who is the person that is standing at the gate.
f)关系代词在从句中做表语
He is not the man that he used to be.
3关系副词引导的定语从句
关系副词可代替的先行词是时间、地点、方式或理由的名词，在从句中作状语。
关系副词when, where, why, how的含义相当于"介词+ which"结构，因此常常和"介词+ which"结构交替使用.
例如：
There are occasions when (on which) one must yield.
Beijing is the place where (in which) I was born.
Is this the reason why (for which) he refused our offer?
I'm surprised the way how (by which) he works out the problem.
注意：
①在非限制性定语从句中，"介词+ which"结构不能代替关系副词。
如：They set up a state for their own , where they would be free to keep Negroes as slaves.
②含有介词短语的动词一般不能拆开，介词仍放在动词后面。
Is this the book which (that) she was looking for?
3名词/数词/代词 /形容词最高级 + 介词 + 关系代词引导定语从句
She has written a book , the name of which I have forgotten.
There are fifty-five students in our class , all of whom are working hard.
There are five continents in the world , the largest of which is Asia.
4as, which 引导非限定性定语从句的差别
由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于and this或and that。As一般放在句首，which在句中。
As we know, smoking is harmful to one's health.
The sun heats the earth, which is very important to us.
as可引导非限制性从句，常带有“正如”的意思。
As is know, smoking is harmful to one's health.
用法区别：
(1) as 引导的定语从句可置于句首，而which不可。
As we all know, he never smokes.
(2) as 代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词;若为行为动词，则从句中的关系代词只能用which。
(3)非限定性定语从句中出现expect, think, suppose 等表示猜测、想象、预料等时。
She succeeded in her doing the research work , as we expected.
(4)As 的用法 the same? as; such?as 中的as 是一种固定结构, 和??一样??。
I should like to use the same tool as is used here.
We should have such a dictionary as he is using.
