自力 主格可以算长短 谓语动词状语从句常识 点的延长 ,所以假如 还没控制 非谓语动词及状语从句的省略的,请慎入,哈哈。

界说 :非谓语动词作状语,其逻辑主语须与主句主语坚持 一致。若纷歧 致,非谓语动词情势 须另带主语,从而组成 复合构造 的情势 作状语。这种构造 称为“自力 主格构造 ”。个中 ,非谓语动词自动 用如今 分词,被动用曩昔 分词。

自力 主格构造 重要 用于描写 性文字中,其感化 相当于一个状语从句,常用来表现 时光 、原因、前提 、行动 方法 或随同 情形 等,如:

表现 时光 :

The meeting over, all of us went home.

Her work done, she sat down for a cup of tea.

表现 前提 :

The condition favorable, he may succeed.

表现 原因:

He wrapped her up with great care, the night dark and frosty.

In the middle of February, the weather favorable for work, the workers began to repair and secure the dam of the river.

表现 随同 情形 :

Almost all metals are good conductors, silver the best of all.

所以其情势 为:

1. 名词/主格代词+分词:

名词/主格代词+如今 分词(表现 自动 和正在进行),

如:

The girl staring at him (= As the girl stared at him), he didn't know what to say.

Time permitting (= If time permits), we will go for an outing.

名词/主格代词+曩昔 分词(表现 被动和已完成),

如:

The problems solved (= As the problems were solved), the quality has been improved.

Her glasses broken (= Because her glasses were broken), she couldn't see the words on the blackboard.

2. 名词/主格代词+不定式:(表现 将要产生 的动作,自动 关系)

如:

He is going to make a model plane, some old parts to help.

They said good-bye to each other, one to go home, the other to go to the bookstore.

3. 名词/主格代词+介词短语

如:

The boy goes to the classroom, book in hand.

Mary was sitting near the fire, her back towards the door.

4. 名词/主格代词+形容词

如:

An air accident happened to the plane, nobody alive.

So many people absent, the meeting had to be called off.

5. 名词/主格代词+副词

如:

He put on his sweater, wrong side out.

6. 名词/主格代词+名词

如:

His first shot failure,he fired again.

Two hundred people died in the accident, many of them children.

7. with引诱 的自力 主格

与主句逻辑关系慎密 ,情势 为with/without+宾语(名词/代词)+宾语补足语(分词/不定式/形容词/副词/介词短语),宾语平日 由名词或代词充任 ,但代词必定 要用宾格。上文的自力 主格构造 的几种情形 都实用 于此构造 ,

如:

The girl hid her box without anyone knowing where it was.(分词)

Without a word more spoken, she left the meeting room. (分词)

The kid feels excited with so many places of interest to visit. (不定式)

With his son so handsome, the old man felt satisfied.(形容词)

The boy was walking, with his father ahead.(副词)

He stood at the door, with a computer in his hand.(介词短语)

8. each引诱 的强调型自力 主格,情势 为:句子+复数名词结尾+each+介词短语/形容词短语/名词短语/分词

如:

The huge organization that operates the company's basic businesses will be divided into five groups, each with its own executive.

留意 :

1. 自力 主格转换成状语从句,当状语从句的主语与主句的主语不是指统一 个对象时,可用自力 主格构造 代替 状语从句,但不再保存 连词,

如:

After class was over (= Class being over / Class over), the students soon left the classroom.

2. 不克不及 省略being (having been)的情况 :

(1) 自力 主格的逻辑主语是代词时,

如:

It being Sunday, we went to church.

(2)在There being+名词的构造 中,

如:

There being no bus, we had to go home on foot.

3. 在“名词/主格代词+介词短语”组成 的自力 主格构造 中,一般不消 形容词性物主代词和冠词,领会 与with引诱 的自力 主格的差别 ,

如:

Miss Smith entered the classroom, book in hand.

Miss Smith entered the classroom with a book in her hand.

在with/without构造 中,多半 情形 下with能省略,但without不克不及 省略。

4. 自力 主格构造 的逻辑主语为名词时,没有所有格情势 ,

如:

The chief-editor arriving, we began the meeting.
