Grammar point Purpose: To get Ss to know about the past participle.

1. Get Ss to complete the sentences and know about the past participle

2. Explain the grammar point for Ss. (1) 过去分词做定语：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防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) 过去分词作表语：

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) 过去分词作宾语补足语：

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。

3.Practice Purpose : To get Ss to know how to use the past participle through

exercises (1) Ask Ss to finish Ex1, Ex2 and Ex3 on P24 and check the answers in pairs. (2) Ask Ss to finish Ex1 and Ex2 on P65 and check the answers in pairs.
