What’s Predicative?
表语是用来说明主语的性质,身份,特征和状态。表语须和连系动词一起构成句子的复合谓语。表语一般放在系动词之后。表语可以由名词,形容词或动名词和形容词作用的词和短语担任。?
What’s object complement?
宾语补足语是对宾语的补充，使得句子的内容更完整更充足。
英语中有些及物动词，接了宾语意义仍不完整，还需要有一个其他的句子成分，来补充说明宾语的意义、状态等，称为宾语补足语，简称宾补。
Draw conclusions:
A. 过去分词可放在系动词be, get, feel, remain, seem, look, become等之后作表语，表示主语所处的状态。
When I got to the classroom, the door was locked.
B. 过去分词作表语（系表结构）与被动语态的区别
“be+过去分词”表示状态时，是系表结构，其后面通常不加by短语，此时分词通常已形容词化；表示动作时，是被动语态，且被动结构中的动作执行者由介词by引出。
My glasses are broken. 我的眼镜碎了。（系表结构，强调状态）
My glasses were broken by my son. 我的眼镜被我儿子摔碎了。（被动语态，强调动作）
C. 过去分词作宾语补足语表示的语法含义是“被动和完成”。考查主要体现在以下几个方面：
过去分词在have, make, get, keep, leave等使役动词的宾语后面充当宾语补足语。
She raised her voice to make herself heard by all the people in the hall.
