系动词和助动词
一、动词概述
二、连系动词
系动词亦称连系动词(Link Verb),作为系动词,它本身有词义,但不能单独用作谓语,后边必须跟表语(亦称补语),构成系表结构说明主语的状况、性质、特征等情况。系动词后不可接副词,接的是形容词。大致分七种
1状态系动词
用来表示主语状态,只有be一词,例如:
He is a teacher. 他是一名教师。(is与补足语一起说明主语的身份。)
2持续系动词
用来表示主语继续或保持一种状况或态度,主要有keep, rest, remain, stay, lie, stand, 例如:He always kept silent at meeting. 他开会时总保持沉默。
This matter rests a mystery. 此事仍是一个谜。
3表像系动词
用来表示"看起来像"这一概念,主要有seem, appear, look, 例如:
He looks tired. 他看起来很累。
He seems (to be) very sad. 他看起来很伤心。

This kind of cloth feels very soft.
这种布手感很软。
This flower smells very sweet.
这朵花闻起来很香。
5变化系动词
这些系动词表示主语变成什么样,变化系动词主要有become, grow, turn, fall(asleep), get, go, come, run.
例如:
He became mad after that. 自那之后,他疯了。
She grew rich within a short time. 她没多长时间就富了。
6终止系动词
表示主语已终止动作,主要有prove, turn out, 表达"证实","变成"之意,例如:
The rumor proved false. 这谣言证实有假。
The search proved difficult. 搜查证实很难。
His plan turned out a success. 他的计划终于成功了。(turn out表终止性结果)
7.使役动词:let,have,make 使,让…
Let /make somebody do sth
The teacher lets/makes them clean the classroom after school.
Make sb/sth adj.
The story makes me happy. The color makes it look beautiful.
Have somebody do sth 让某人做某事
Have sth done 让某物被
My mother haves me make the bed. I have my hair cut/washed.
有些动词它们既可以用作实义动词,又可以用作连系动词。另外be还可用作助动词。它们的用法不同,词义和句型结构也有所不同。例如:
Look at the blackboard, please.请看黑板。(look用作实义动词)
He looks a little tired.他略显疲倦。(look用作连系动词)
They are at work.他们在工作。(are用作连系动词)
They are working.他们正在工作。(are用作助动词,帮助构成现在进行时)
