the door opened,这句话不完整.你看看你这句话的出处是不是还有别的没写上来.
1.我们补充完整：sb make the door opened（make使）
sb leave the door opened（leave让）
sb keep the door opened（keep保持）
某人使门被打开,或某人使门处于开的状态.因为门是被开的所以用open+ed,由于前面有使动词（make,leave,keep）所以不需要be.
2.opened作定语修饰the door
我们可以理解为定语从句的省略.
完整的定语从句：
...the door( which/that is opened)...
省略连接词和be,保留分词opened
即...the door opened...

the door opened为什么没有被动语态 be the door opened为什么不用被动语态? He opened the door.变被动语态 Who opened the door?改为被动语态. 关于被动语态的表达“门开着.”这个句子是翻译成：The door open 还是the door is opened?“ I open the door 的被动语态 the door 应该是is opened,为什么还有the door opened啊 The door opened and() S(),the door opened 被动语态可以没有be动词? 被动语态怎么没有be动词呢? They have painted the door already.(改为被动语态)
