Explain the grammar point for Ss. 1)过去分词作定语

表示分词动作与所修饰的名词之间存在被动关系。单一的过去分词做定语一般放在被修饰的名词之前；过去分词短语做定语放在被修饰的名词之后，过去分词及过去分词短语做定语均可以转换

为一个定语从句。

2）过去分词做表语

过去分词做表语，表示主语的状态，且该状态通常是由外界因素引起的。这时过去分词可以被看作一个形容词，是形容词化的过去分词。

3）过去分词做宾语补足语

做宾语补足语的过去分词一般是及物动词，和宾语有逻辑上的主谓关系。可以带过去分词做宾语补足语的动词有：

1. see, hear, watch, feel, think, find等表示感觉和心理状态的动词。

2. make, get, have, help, leave等表示“致使”意义的动词。

3. like, want, wish, order等表示“希望，要求”等意义的动词。
