1． 规则动词的-ed形式

pretend→pretended（假装）
escape→escaped（逃脱）
provide→provided（提供）
refer→referred（提交）
drag→dragged（拖）
pray→prayed（祈祷）
supply→supplied（供应）
2．不规则动词的-ed形式

spread→spread（传播）
bite→bitten（咬）

3．少数动词的-ed形式作定语时，读音与一般过去分词不同

B．动词的-ed形式的否定形式
动词的-ed形式的否定形式是由not或never加动词的-ed形式构成。

Never invited to his party, she got angry with him. 从未被邀请过去他的聚会，她很生气。
C．动词的-ed形式的特征
动词的-ed形式有被动的意思，有时也可表示完成的动作。
1．动词的-ed形式表示已完成的动作。
除了作形容词用的-ed形式外，动词的-ed形式可带有完成的意义，有的同时也带有被动的意义。

3．不及物动词的-ed形式只表示完成的意思，并不带有被动的含义。

动词的-ed形式在句中主要起形容词和副词的作用，可以作定语、表语、状语和补语。
A．动词的-ed形式作表语
1．-ed形式在连系动词后作表语，说明主语的状态。
The students are fully prepared. 学生们已做好了充分的准备。

要把-ed形式作表语和被动语态区别开来。作表语的-ed形式表示状态，被动语态中的-ed形式表示被动动作。

All the doors were locked by the guard. 所有的门都被卫兵锁上了。（被动语态，表示动作）
