2023年初中英语词汇语法之系动词讲解分析
系动词的概念:
连系动词(link verb)是一个表示谓语关系的动词。它必须后接表语(通常为名词或形容词)。连系动词的功能主要是把表语(名词、形容词、某些副词、非谓词、介词短语、从句)和它的主语联系在一起,说明主语的属性、特征或状态。它有自己的但不完全的词义,不能在句中独立作谓语,必须和后面的表语一起构成句子的谓语。它是虚词。
系动词的分类:
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:The weather will continue cold and wet.
He remained poor after 20years.
The shop will stay open at 11:00p.m.
He stood/sat silent there.
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:She appears to have know this thing.
She seems a student.
4、感官系动词:
感官系动词主要有feel, smell, sound, taste。
例如:The silk feels soft.
Your idea sounds a good one.
He looked like his mother.
The mixture tasted terrible.
The flower smells sweet.
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, get, go, come, run。
例如:My dream o fcoming to China has come true.
In summer food often goes bad.
He turned doctor./ He became a doctor.
He fell asleep as soon as he went to bed.
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 truth he stuck to proved true.
系动词基本用法:
连系动词是表示不完全谓语关系的动词,它与其后的表语一起构成谓语。
常见的连系动词有be(是),become(成为),get(变成),remain(还是),seem(似乎是),look(看上去),feel(感觉)等。
连系动词后的表语通常是名词和形容词,有时也可以是代词、数词、副词、介词短语、不定式、动名词、从句等:
如:His English is excellent. 他的英语很棒。(跟形容词)
He is a famous poet. 他是著名诗人。(跟名词)
Money isn't everything. 金钱不是一切。(跟代词)
She was the first to arrive. 她是第一个到达的人。(跟数词)
Who is up stairs? 谁在楼上?(跟副词)
He is with his friends. 他和朋友在一起。(跟介词短语)
He seems to be ill.他似乎病了。(跟不定式)
Seeing is believing. 眼见为实。(跟动名词)
This is what you need. 这就是你需要的。(跟从句)
注:有些系动词又是实义动词,该动词表达实义时,有词义,可单独作谓语。
例如:1、She tasted①the soup to see if it tasted②too salty. 她尝了一口汤,看是否太咸。
2、The doctor is feeling①his pulse because he feels②sick. 因为身体不舒服,医生正在给他切脉。
3、The mother looked①at the sick child sadly and she looked②sad. 母亲难过地看着生病的孩子。
4、She smelled①the meat to make sure it still smelled②good. 她闻了闻肉,看看是否还新鲜。
5、The teacher asked the students to keep②quite when they were keeping①everything in order. 当学生整理东西时,老师让他们保持安静。
从以例子不难出,标①的动词为实义动词,他们后跟有宾语;标②的动词为系动词,其后往往跟形容词、名词、不定式等作表语。
系动词知识体系:
连系动词使用应注意的两点:
1、关于连系动词后接副词作表语:
连系动词后通常可接形容词作表语,一般不接副词:
误:His English is very well. 他的英语很好。(应将well改为good)
误:Be carefully. 小心点。(应将carefully改为careful)
误:The soup tastes nicely. 这汤味道不错。(应将nicely改为nice)
但是,有时连系动词后也可接副词作表语,不过这主要限于in, on, off, out, away, behind, up, down, over, through, around, round, below, inside,
