sell有无被动语态如何区分

回答如下：

英语动词sell能否使用被动语态取决于其词义以及是否是及物动词。现简述如下：

1、 动词sell作及物动词表示“卖”的具体动作，其主语是人或机构。例如：

1) He sold his house to Mary. (= He sold Mary his house. ) 

被动语态：His house was sold to Mary by him. 

2) We sold the computer for two thousand yuan. 

被动语态：The computer was sold for two thousand yuan by us. 

We have sold out the books. 

被动语态：The books have been sold out. 

2、 动词sell作不及物动词表示“卖”的状态或物品的销售情况，其主动形式可以表示被动的意思。例如：

The book sells well. 这本书很畅销。
