连系动词(link.v),不及物动词(vi)和及物动词(vt)的区别
一、系动词(link-v)。 句子结构:①主语+系动词+表语(S+V.+P)
连系动词不能独立做谓语,必须跟表语一起构成谓语。系动词后的表语可以是名词、代词、数词、形容词、分词、动名词、不定式、副词、介词短语、词组、从句等。系动词无被动形式。
(1) 表示特征或状态: be, look, seem, appear, smell, taste, sound, feel, turn out, prove等。
1) It sounds a good idea.
2) This food tastes good.
3) The door remained closed.

(2) 表示持续: keep, remain, stay, lie, stand等。
1) I hope you will keep fit.
2) We can remain friends.
3) Please stay seated.

(3) 表示变化: become, go, get, grow, turn, fall, come, run等。
1) He went mad.
2) His hair turned grey.
3) I fell ill.

二、不及物动词。不及物动词后面通常不跟宾语,且无被动形式。句子结构:②主语+不及物动词(S+Vi)。
1) Birds can fly.
2) I can jump high.
其他不及物动词:agree, arrive, arise, belong, come, die, dive, exist, fall, flow, go, happen, hurry, rise, listen, look, rise, run, sit, sail, succeed walk, work, stay等.
不及物动词若要跟宾语,必须在其后加介词方可再接宾语(Vi+prep.+O).
1) Look at me !
2) Sit on the stool!

三、及物动词。及物动词后面必须跟宾语,且可以用于被动语态。句子结构如下:
1. ③主语+及物动词+宾语(S+Vt+O)
He reached Paris the day before yesterday.
还有forget, receive, see, say, supply, select, show, take, raise, visit, spend等

2. ④主语+及物动词+间接宾语(人)+直接宾语(物)(S+Vt+sb+sth)
1) Please show me the letter.
2) Please hand me the book over there.
3) Can you buy me a meal?
4) John has sent Betty a cheque of $1000.
5) I will give you the latest newsletter.
6) She made me a beautiful dress.
若要先说出直接宾语(事物),后说间接宾语(人),则要借助于介词to或for, 如:

1) He brings cookies to me every day.
2) She made a beautiful dress for me.

常跟双宾语的动词:
(需借助to的) ask, bring, give, lend, hand, offer, pass, pay, promise, return, send, show, teach, tell, write等。
(需借助for 的) buy, call, cook, choose, find, get, make, order, sing, save等。

3. ⑤主语+及物动词+宾语+宾补(S+Vt+O+O.C)
宾补的定义:有些及物动词带了宾语后还需要有一个补足成分才能使句子完整,这个补足成分就叫做宾语补足语,用来说明宾语的行为、特征、状态、身份等。宾语和宾补一起构成复合宾语。
主要有下面几种类型:
1. Vt+宾语+名词 She found him a very clever boy.
2. Vt+宾语+形容词 He had a strange way of making his class lively and interesting.
3. Vt+宾语+副词或介词短语 To her surprise, she found herself in a different world.
4. Vt+宾语+to do They asked me to go fishing.
类似动词:tell, beg, force, wish, want, expect, advise, permit, order, persuade等
5. 及物动词+宾语+doing/do/done
I saw you taking the key out of your pocket when I came in.
I saw you take the key out of your pocket.= I saw the key taken out of your pocket.
类似动词:see, watch, notice, hear, feel, have等

四、既可以用作及物又可以用作不及物的动词,其意义不变。
1) Our game begins.
2) Let us begin our game.
3) “I’m sorry,” he answered.
4) He didn’t answer my question.
类似动词:start, sing, close, consider, read, learn, prepare, pay, hurt, improve, increase…

五、既可以用作及物又可以用作不及物的动词,其意义完全不同。
1) He lifted his glass and drank. (vt举起)
2) We saw the mountain when the clouds lifted(vi消散).
类似动词:beat (vi.跳动 vt.打)  grow (vi.生长 vt.种植) hang (vi.悬挂 vt.绞死)  smell (vi.闻起来 vt.嗅)
