英語六級(jí)備考必備知識(shí)之獨(dú)立主格結(jié)構(gòu)
獨(dú)立主格結(jié)構(gòu)可以分為兩部分:一部分是名詞或代詞,起邏輯主語的作用;另一部分是非謂語動(dòng)詞分句(現(xiàn)在分詞、過去分詞、不定式)或無動(dòng)詞分句(名詞、形容詞、副詞、介詞短語),表示前面名詞或代詞的動(dòng)作或狀態(tài)。
1. 名詞/代詞+ 現(xiàn)在分詞
現(xiàn)在分詞表示前面的名詞或代詞主動(dòng)進(jìn)行的動(dòng)作或狀態(tài)等。
例 The man lay there, his hands trembling.
So many students being absent, the meeting had to be put off.
His homework having been done, Tom went to sleep.
注:“獨(dú)立結(jié)構(gòu)”中的being或 having been 有時(shí)可以省去,這樣就成了無動(dòng)詞分句或過去分詞分句。
2. 名詞/代詞+過去分詞
過去分詞表示前面的名詞或代詞被動(dòng)完成的動(dòng)作或所處的一種狀態(tài)。
例 The boy lay on his back, his hands crossed under his head.
The job not finished, we couldn’t see the film.
Her shirt caught on a nail, she could not move.
后面兩個(gè)句子也可以看成省略掉了having been,being。如果加上,這兩個(gè)句子就又變成了現(xiàn)在分詞分句。
3. 名詞/代詞+不定式
不定式表示的是將來的動(dòng)作。
例He suggested going for a picnic, Mary to provide the food.
These are the first two books, the third one to come out next month.
We shall get together at 7:30, the procession(游行) to start moving at 8 sharp.
4. 名詞/代詞+名詞
名詞一般做前面名詞或代詞的同位語。
例 Many people joined in the work, some of them women and children.
He fought the tiger,a stick his only weapon.
5. 名詞/代詞+形容詞短語
形容詞(短語)說明前面名詞或代詞的性質(zhì),狀態(tài),原因等。
例The floor wet and slippery, we had to stay outside for a while.
I heard that she got injured in the accident, my heart full of sorry.
這兩個(gè)句子也可以看成是省略了being,如果加上,就變成了現(xiàn)在分詞分句。
6. 名詞/代詞+副詞
副詞說明前面名詞或代詞的狀態(tài)。
例 The meeting over, we all went home.
Nobody in, he left a message on the board.
He sat at the table, head down.
7. 名詞/代詞+介詞短語
介詞短語說明伴隨前面名詞或代詞的方式或者狀態(tài)。
例 The teacher came in, a book under his arm.
The hunter entered the forest, gun in hand.
Nobody at home, the thief took a lot of things away.
8. with引導(dǎo)的復(fù)合結(jié)構(gòu), 也可以認(rèn)為是一種獨(dú)立主格結(jié)構(gòu)
例 A woman got on the bus with a baby around her arms.
The teacher came in with several students following behind.
With a lot of things to deal with, he will have a difficult time.
With the work done, he went out to eat.
He left the office with the lights on.
Mary rushed out of the house with the door open.
