What Is Subject

2. V (verb) 谓语动词
说明或描述主语的行为动作或所处的状态，由动词或动词短语充当，位于主语之后。

__________
__________
What Is Object
3. O (object) 宾语
宾语有单宾语、双宾语、复合宾语等。双宾语又分为直接宾语(DO)和间接宾语(IO)。宾语可以由名词(短语)、代词、数词、名词化的形容词不定式(短语)、动名词(短语)、从句等充当。

What Is Predicative
4. P (predicative) 表语
表语说明主语的身份、特征或状态，在系动词（be、become、get、look、grow、turn、seem等）之后，可以由名词、代词、形容词、分词、不定式（短语）、动名词（短语）、介词短语以及从句充当。

What Is Adverbial
5. A (adverbial) 状语
修饰动词、形容词、副词或整个句子，说明动作或状态特征的句子成分称为状语。状语的位置非常灵活:修饰形容词、副词时通常放在被修饰词之前;通常在句子的基本结构之后;强调时放在句首。
He knows a lot.
She is lying in the bed.
When I was young, I often listened to the radio.

What Is C (Complement)
6. C (object complement) 宾语补足语
有些及物动词除有一个宾语外， 还要有一个宾语补足语，才能使句子的意义完整。
一般结构为:及物动词(如 make、 see、find等)+宾语+宾语补足语。
New technologies make life easy and convenient.
注意:“make/ see/ find... sb. do sth."结构变为被动形式时，不定式符号to要还原。
