如何区别英语中句子成分？句子

主语：用来表示句子主要说明的人或事物，一般用名词、代词或想的党羽名词的词、短语或句子来担当。

A 动词变成动名词如：Playing basketball is my favorite sport.

B The 形容词 表示一类人，也具有名词功能，也可以做主语 如：The rich should help the poor

C 陈述句做主语时，常用连接词that 引导，that不能省略

That we are scoring goals is good.

谓语：谓语由动词来充当，说明主语所做的动作或具有的特征和状态。

简单谓语：有一个动词或动词短语构成如： he reads newspapers every day.

复合谓语：由情态动词或其他助动词加动词构成，表现英语语言的丰富性,其中疑问句和否定句的助动词也是谓语的一部分。

如

you may keep the book for two weekshe has caught a bad cold.my siser is crying over there.has he e back?he didnot attend the meeting yesterday.

宾语是动词的对象，作为宾语的一般为名词、代词或者相当于名词的词，短语或者从句。宾语分为动词宾语和介词宾语。

【注意】有时候副词，介词短语也可以做宾语。如：

he left there just nowhe came out from under the bed.

【双宾语】

动词后面跟双宾语时，一般是间接宾语在前，直接宾语在后

verb sb. sth.=verb sth. for sb. verb sb. sth.=verb. sth. of sb.

【宾语补足语】

宾语补足语和宾语构成逻辑上的主谓关系。宾语和宾语补足语一起构成了复合宾语，可以做宾语补足语的有名词、形容词、介词短语、非谓语动词等。

名词或名词性从句做宾补

they call the dog Tom.
