介词是英语中虚词的一种,其搭配能力很强。但不能在句子中独立充当成分,而总是后面加名词、代词、或相当于名词的其他词类、短语或从

句,一起构成介宾短语,在句子中充当成分。

I was born in April in a small village.(名词)

I owe my success to her.(代词)

He devoted himself to teaching.(动名词)

He was busy in writing his homework.(现在分词短语)

He lives in what we now call California.(宾语从句)

一、介词短语的构成

英语介词短语可分为四类:即简单介词+宾,如:before、since等;合成介词+宾,如:throughout、without等;短语介词+宾,如:with

regard to、apart from等;分词介词+宾,如:considering、concerning等。

二、介词短语的语法功能

1.作状语,修饰动词、副词或者整个句子,作状语,表时间、地点、原因、结果、让步、条件、方式、目的、伴随、方向及程度等。

(1)修饰动词。

The girl died in the accident as a result of his carelessness.(原因状语)

He got up late. As a result, he was late for work.(结果状语)

Despite the bad weather, they went out anyway.(让步状语)

Without water, fish can not live.(条件状语)

They crossed the river by means of a bridge.(方式状语)

He lives for nothing but money.(目的状语)

The teacher came in with a book under his arm.(伴随状语)

They moved towards the end of the street.(方向状语)

He is older than his brother by two years.(程度状语)

(2)修饰副词。

John is now somewhere on the high seats.(地点状语)

(3)修饰整个句子。

On the whole, Jack has been a good friend.(邏辑状语)

2.作定语,通常放在名词或代词后作后置定语。

He is a man of enterprise.(有事业心的人)

I found a part-time job of being a volunteer.(一份志愿者的兼职工作)

3.作表语,放在系动词后,构成主系表结构。

The boy remained in the university for another year.

4.引出宾语,用在不及物动词、不及物动词短语或形容词后。

They have been waiting for you all the time.(wait vi.,加宾语需补for)

The parents gave in to their kid finally.(give in 不及物短语,加宾语需补to)

The professor asked the student about his financial situation.(ask b. about sth.)

He was not aware of my presence in the room.(be aware of nth.形容词宾语)

5.作宾补

We made the sofa in the center of the room.(make nth.+prep.+n.;动词宾补)

The woman sat there with a baby in her arms.(with+n.+ prep.+n;介词宾补)

6.如果想作主语或宾语,换成being+prep.+n. 形式。

Being at school all day really makes me bored and tired.(作主语)

He enjoyed being in the library when he was at college.(作动宾)、 The man was fond of being by himself.(作介宾)

三、介词短语词块在长难句断句中的应用

英语中很多长难句都是简单句基础上的介词短语和引导词引导的从句串联而成,因此。了解介词短语的用法,辅之以从句知识,有助于拆分句

子,更好地理解句意。如:

Scientists believe/that these settlers crossed the Bering Strait/in the Arctic/

(宾语从句) (后置定语)

to America/by means of a land bridge/which existed/in prehistoric times.

(方向状语) (方式状语) (定语从句) (时间状语)

四、巩固练习

1. Dont confuse yourself/by living/for nothingness/on Sunday morning/or

(方式状语) (目的状语) (时间状语) (并列词组)

2.living/for self/for the rest of the week.

(目的状语)(时间状语)

3. This technology did not spread/to Europe/until the 19th century, and it was/

(地点状语) (时间状语) (强调句)

4.by using the technology/that/the Americans drilled the first oil well/in

(方式状语) (强调句) (地点状语)

5.Pennsylvania/in 1859.

(时间状语)

掌握了介词短语的结构特征与语法功能,除了划分长难句,有助于理解阅读篇章,也可以在写作中大量使用该结构,使文章更地道。
