3. 宾语：
分为动词宾语和介词宾语，属于动作的承受者。
例如：He's playing soccer.
Good food and exercise help me to study harder.
4. 系动词：
表示状态或状态变化的动词，没有实际的动作意义。如 be, 感官系动词(look, sound, smell, taste 和 feel)、保持类系动词(keep, stay 和 remain)、状态变化类系动词(become、get、turn 和 go)等。
This picture looks so beautiful.
Keep working, you will see the post office on your right.
5. 表语：
紧跟系动词后面的成分。说明主语是什么或者怎么样，由 n. adj. 或者相当于名词或形容词的词或者短语，和系动词一起构成谓语。
例如：Her mother is a bank clerk.
Are you ready?
We were at home last night.
6. 定语：

修饰形容词、副词、动词或句子的成分。一般表示行为发生的时间地点目的方式程度等意义。通常有副词、介词短语或相当于的副词的词或短语来表示。
例如：People are all working hard.

8. 补语：
分为宾语补足语和主语补足语。是对宾语和主语的补充说明，与其有主动或被动的逻辑关系。
例如：You should keep the room clean and tidy.
你应该让屋子保持干净整洁。
(You是主语， should keep是谓语，the room是宾语，clean and tidy是宾语补足语。)
This kind of food tastes delicious.
这种食物吃起来很可口。
(This kind of food是主语， tastes是系动词， delicious是表语。)
注意：主语、谓语、宾语、系动词、表语、补语是一个句子的主干成分;定语和状语是一个句子的修饰性成分，不是主干成分。
