英语句子成分划分详解

概念

句子是由词按照一定的语法结构组成的。组成句子的各个部分叫做句子的成分。句子的成分包括：主语、谓语、表语、宾语（直接和间接宾语）、宾语补足语、定语和状语。主语和谓语是句子的主体部分（在英语中，一般句子必须有主语和谓语），表语、宾语和宾语的补足语是谓语里的组成部分。其他成份如定语和状语是句子的次要成分。 句子成分分类

1．主语

主语是谓语讲述的对象，表示所说的“是什么”或“是谁”。一般由名词、代词、不定代词或相当于名词的单词或短语来充当，也有从句充当的现象。大多数主语都在句首。如： 讲述“谁”-----人 We work in a big factory.

讲述“什么”----物

The classroom is very big.

数词作主语----人或物 Three are enough. 三个人就够了

不定式作主语-----事《相当于语文中的短语：争取冠军是有可能的》

To operate on the blind is one of the ORBIS Doctor ’s job.

从句作主语------一件事（句子）《例：张三打人是不对的》

What we need is food. 我们最需要的是食物.

▲ 在“There be …”句型中，主语的位置在中间。如：

There are some bottles of milk in the box.《some bottles of milk are in the box.》

▲ 在个别句型中，主语在整个句子后面，这时前面用it 作形式主语。如： It is very interesting to play the game called “treat or trick ”.

It took two workers about three months to build the house. 2．谓语

谓语时用来说明主语“做什么”、“是什么”或“怎么样”，谓语必须是动词，谓语和主语在“人称”和“数”两方面必须一致。如：

He is very generous.

She looks very smart and cool

We have finished the job. 没有区别嘛

it 也是代表的一件事

He can speak German. （can 在中文中是助词，帮助动词的，状语；英语中叫情态动词，作状语）

3．表语

表语说明主语“是什么”或“怎么样”，由名词、形容词、介词、副词、不定式及相当

叫系动词了（是/呈现/

象

/ 形容词作表语

You are younger than before.

名词作表语

My father is a teacher.

副词作表语

Everyone is here.

介词短语作表语

They are at the

不定式作表语

4充当，它和谓语动词一起说明主语是什么，通常放在谓语动词后面。有时，会有双宾语。如：

名词作宾语

He never forgives others for their mistakes.

代词做宾语

He often helps me.

不定式作宾语

He likes to sleep in the open air.

动名词作宾语

从句做宾语I believe the work in time.（及时） We bought （BUY ） them some food.主 谓。

5．宾语的补足语 还必须在宾语后面加上宾语的补足语才能表达完整的意思。我们把“宾语＋宾语补足语”合起来称为复合宾语。复合宾语所表达的意思相当于一个句子的意思。名词、动词、形容词、副词、介词短语、不定式、现在分词、过去分词都可以作宾语补足语.如:

名词作宾补

If you let me go, I ’ll make you king.

形容词作宾补

Don ’t make hands dirty.

副词作宾补

We found Li Ming out when we arrived.

介词短语作宾补

Make herself at home.

省略to 的不定式作宾补

I saw a girl go into the house.

带to 的不定式作宾补

The boy ordered the dog to lie down.

在英语中,常见的“宾语＋宾语补足语”的结构有：

▲“宾语+名词”。常用于改结构的动词有：call, name, make, find, choose, think, leave 等。

We call him Jack.

They made Li Lei their monitor（班长）.

▲“宾语+形容词”。常见的动词有think, believe, leave, drive, make, keep, turn, wish, want等。如：

Do you think his idea wrong?

We must keep. our classroom clean

We can’t leave him alone（单独）.

Can you get everything ready for the party before Friday?

▲“宾语+副词”。副词作宾补常表示宾语的状态，与宾语有逻辑上的主表关系。常见的副词有：down, up, here, there, home, in, out, anywhere等。如： Let him in/ out.

Mr. Li drove us home.

When got there, we found him out.

▲“宾语+介词短语”。介词短语作宾补常表示其逻辑主语（即宾语）所处的状态，两者有主表的关系。如：

We found everything in good order.

We regard him as our good friend.

He find out some of his friends in the rain.

▲“宾语+不定式”。充当宾补的不定式有三种：

A 要求带to的不定式

The cool water of the lake invited us to swim.

B 要求不带to 的不定式 let, make, see, hear, watch等

The boss made the workers work 12 hours a day.

I often hear him read English in his room.

C 单词help 后可加 to 或不加 to

She sometimes helps her mother (to) do housework.

6．定语

▲定语用来修饰名词或代词。形容词、代词、数词、名词、介词短语、不定式或相当于形容词的词或短语等都可以充当定语。因为它是修饰名词或代词的，而名词和代词可以作主语、表语或宾语，所以定语的位置很灵活，凡是有名词、代词的地方都可以有定语。如：形容词作定语

The black bike is mine.
