英语语法句子成分分析
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
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” We work in a big factory.
讲述“什么” The classroom is very big.
数词作主语 Three are enough.
从句作主语 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.
▲ 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 toplay the game called “treat or trick”.
It took two workers aboutthree months to build the house.
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.
He can speak German.
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、不定式及相当于名词的词或短语来充当，它的位置在系动词后面。
形容词作表语
You look youngerthan before. 名词作表语
Myfather is a teacher. 副词作表语
Everyone is here. 介词短语作表语
They are at the theatre.不定式作表语
My job is to teach them English. 动名词作表语
Her job is training the nurses.从句作表语
宾语
▲宾语是动作、行为的对象，由名词、代词、不定式、或相当于名词的词或短语或从句来充当，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 theopen air.
动名词作宾语The Americans enjoyed livingin China.
从句做宾语 I believe that they can finish the work intime.
▲直接宾语和间接宾语
及物动词作谓语时，后面要跟宾语，宾语分直接宾语和间接宾语。直接宾语是及物动词的对象。但有些动词除了直接宾语外，还需要有一个间接宾语，间接宾语表语动作是对谁做的，所以只能用名词或代词来充当。如：
We brought themsome food.
主 谓 间宾 直宾
间接宾语可以放在直接宾语后面，但必须加to 或 for。
宾补
在英语的句子中有些句子里只有宾语并不能表达完整的意思，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巨资的意思。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 your hands dirty.
副词作宾补 We found Li Ming out when we arrived.
介词短语作宾补Make yourself at home.
省略to的不定式作宾补I saw a girl go into the building.
带to的不定式作宾补 The boy ordered the dog to lie down.
现在分词作宾补The boss kept them working all day.
过去分词作宾补Yesterday he got his leg broken.
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 himJack.
They made Li Lei their monitor.
▲“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.
▲“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 droveus 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 opened the door and found 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
B要求不带to的不定式let, make, see, hear, watch等
C 单词help 后可加 to
