2复合谓语：由“情态动词+动词原形”构成

(3)表语
表语是谓语的一部分，它位于系动词如be之后，说明主语身份，特征，属性或状态。一般由名词，代词，形容词，副词，不定式，介词短语等充当。

(4)宾语
宾语表示动作行为的对象，跟在及物动词之后，能作宾语的有名词，代词，数词，动词不定式等。

有些及物动词可以带两个宾语，往往一个指人，一个指物，指人的叫间接宾语，指物的叫直接宾语。

有些及物动词的宾语后面还需要有一个补足语，意思才完整，宾语和它的补足语构成复合宾语。如：
We make him our monitor.我们选他当班长。
(5)定语
在句中修饰名词或代词的成分叫定语。 用作定语的主要是形容词，代词，数词，名词，副词，动词不定式，介词短语等。形容词，代词，数词，名词等作定语时，通常放在被修饰的词前面。

但副词，动词不定式，介词短语等作定语时，则放在被修饰的词之后。
The bike in the room is mine.房间里的自行车是我的。
(6)状语
修饰动词，形容词，副词以及全句的句子成分，叫做状语。用作状语的通常是副词，介词短语，不定式和从句等。状语一般放在被修饰的词之后或放在句尾。副词作状语时可放在被修饰的词前或句首。
He lives in London.他住在伦敦。 The children are playing happily.
(7)补语
补语用来说明宾语或主语所处的状态或正在进行的动作，作补语的有形容词、副词、名词、不定式、动词-ing形式、数词等。We will make our country more beautiful.
