职称英语综合类考试：主语补语
We chose him our monitor. I regard the work as easy. I found her an apartment. We invited him to speak at the meeting.
主动语态中的宾语补语在句子变成被动语态后即成为主语补语，如：
He was invited to speak at the meeting. The problem is considered as of no importance.
状语
状语是指修饰动词、形容词、副词、介词短语或整个句子成分。副词（短语）、介词短语、名词（短语）、不定式（短语）、分词（短语）和从句都可作状语。
多数状语在省略后并不影响句意的完整性，称之为任意性状语，如：
They are dancing （hand in hand）。
I heard the singing （in the distance）。
但有些状语在句子中是必不可少的，称之为必具性状语，如：
She lived in Australia. Our products sell very well.
