原标题：高考语法温习系列 系动词的用法
第四章系动词的用法
1. 最常用连系动词：be(am; is/was; are/were)。
2. 表改变的系动词：get; turn; go; fall; become; grow; come; run。用法留意：在英语中，系动词一般只要一般现在 时和一般过去时两种时态改变方式，没有其他时态改变方式。但表改变的这类系动词在外，它们有各种时态改变。
E.g.: It is becoming colder and colder.
The food has gone bad.
此处还需留意的是become和turn后接表作业的名词时冠词的有无：
E.g.: Two years later, he became a teacher.
但Two years later, he turned teacher.
别的，go表改变时一般指作业向消沉、欠好的方面转化。
3. 所谓“感官动词”:look; sound; taste; smell; feel。一般它们在语句中译成：。。。起来；。。。上去。此类系动词为高考高频词。
E.g.: The food tasted good.食物尝起来很香。
其间有必要留意到它们自身也用作实义动词，所以在往常的教育和使用中必定多比较、重视它们的用法。
E.g.: He looked sadly at the picture. / She looked sad after hearing the news.
Tom tasted the food and it tasted good.
4. 表状况的系动词：keep; stay; remain;（依然是；坚持）
E.g.: She remains loyal to her father despite his cruelty towards her.
What a lovely day today! I love fine weather and I hope it will stay fine for some more days.
Much remains to be done.
5. 表像系动词：seem; appear。汉语含义：看起来像、如同、如同。这两个动词有一个一起的特色，即假如要表达时态的改变，需求后接不守时来完结。
E.g.: He seemed to have caught cold./ When Father came in, Tom seemed to be eating something.
别的此处一句型转化也要要求学生紧记
It seemed that he had caught cold.
When Father came in, it seemed that Tom was eating something.
6. 停止系动词：prove; turn out。表达“证明、证明、成果为。。。”之意。
E.g.: He proved (to be) right. / The experiment turned out successful.
1． 一般地说，系动词无进行时态，无被动语态 如：
Your hand feels cold.
The soup tastes good.
The dinner smells good.
2．系动词的时态与形容词的比较级连用的问题。
某些含有改变含义的动态系动词如get, become, grow, turn等的进行时态可与形容词的比较级连用，表明渐进进程，其意思是“越来越……”。例如：
He is growing taller and taller.
Our life is getting better and better.
Things are getting worse.
3．一切半系动词的被动语态要分状况评论。
英语中某动词在作系动词用时，无被动语态，而作实义动词用时，才有被动语态，二者不行相提并论。例如：
不能说：The apple is tasted good.由于taste此刻是系动词，“尝起来”之意，指的是苹果的性质，无被动语态）
但咱们我们可以说：The apple is tasted by me.这苹果被我尝了一下。（taste此刻指“尝一尝”这一动作，有被动语态）
因而，在平常的英语教育和学习之 ，要有意留意半系动词在详细的言语环境中到底是系动词用法仍是实义动词用法，要留意区别、辨认。
4．瞬间动态系动词能否与时刻段连用的问题
英语中某些表明瞬间含义的系动词不能与“for+时刻段，since+时刻点，how long until+时刻,by + 时刻，so far”等直接连用。例如：
①不能说：He has become a teacher for 2 years.
应改为：He has been a teacher for 2 years.
②不能说：He has turned writer since 3 years ago.
应改为：He has been a write since 3 years ago.
或It is two years since he turned writer.
③不能说：He got angry until his child came back home.
应改为：He didn’t get angry until his child came back home.
5．系动词能接几种表语（从句）
系动词除了接adj.n.prep.短语,还可接以下几种表语方式：
①能接as if/as though表语从句的系动词有：look（看起来），smell（闻起来），sound（听起来），feel（觉得）；appear（显得），seem（如同）。例如：
It looks as if we are going to have snow.看样子天要下雪了。
He looked as if he had just stepped out of my book of fairy tales.他看来如同刚从我的童话故事中走出来似的。
She seemed as if (though) she couldn’t understand why Laura was there.看来她如同不能了解为什么劳拉呆在那儿。
It sounds to me as though there’s a tap running somewhere.我如同听到某处水龙头流水的声响。
She felt as if her head were splitting.她好像觉得她的头要裂开了。
The river appeared as if enveloped in smog.那条河如同笼罩在烟雾之中。
It seems as if it were spring already.如同已是春天了。
②可用于“It+系动词+that从句”结构的有：seem, appear如：
It seemed that he had made some serious mistakes in his work.如同他在作业中犯了严重过错。
It appeared that he was talking to himself.如同他在喃喃自语。
③能用不定式作表语的系动词有：be, seem, , look, appear, prove, grow.

He seems not to look after the children.他如同不是她的父亲。
He looks to be a young girl of twenty.他看起来像是一个20岁的年青姑娘。
He didn’t appear to dislike it.看不出他憎恶此事。

④能与there连用的系动词有：be, appear, seem.

There seems(to be)no need to go.如同没有必要走
