Step2 单元语法知识汇总
复习过去分词作定语、表语和宾语补足语
过去分词作定语
1．及物动词的过去分词作定语，表示与所修饰的名词构成被动和完成的关系。这时，相当于一个定语从句。
The meeting, which was attended by a lot of people, was a success. (用分词改写)
→The meeting, attended by a lot of people, was a success.
2．有些不及物动词的过去分词(只限于单个分词，且不能后置)也可作定语，此时只表示完成的动作，而不表示“被动”的意义。
We drank some boiled water and went on with our work.
过去分词作表语
过去分词作表语，表示主语的状态或思想感情等。
When hearing of it, we were deeply moved.
过去分词作宾语补足语
过去分词作宾补，与前面的宾语有逻辑上的动宾关系，即宾语是过去分词动作的对象。
1．过去分词可作表示感觉或心理状态的动词的宾语补足语，这类动词有“see,hear, watch, notice, observe, feel, find, think, consider”等。
She felt a great weight taken off her mind.
2．过去分词可作使役动词的宾语补足语，这类动词有“make,have, get, keep, leave”等。
We will keep you informed of whatever happens.
3．过去分词可作表示希望、要求、命令等动词的宾语补足语，这类动词有“want,like, wish, expect”等。

4．过去分词用在“with＋宾语＋宾补”结构中。
