was+过去分词是什么时态
是一般过去时。was加过去分词时一般过去时的被动语态。被动语态指主语和谓语的关系是被动；或者主语是谓语动作的承受者。被动语态的结构：be+done，这里的动词就是过去分词。语态说明了主语和谓语的关系，任何一个句子都有时态的使用。所以不同时间，不同关系，使用的被动语态形式也不同。 扩展资料
使用被动语态应注意： 1、不及物动词无被动语态。 What will happen in 100 years.
The dinosaurs disappeared about 65 million years ago. 2、有些动词用主动形式表示被动意义。 This pen writes well. This new book sells well.
3、感官动词或使役动词使用省略to的'动词不定式，主动语态中不带to ，但变为被动语态时，须加上to 。
例：make somebody do something→somebody+ be +made to do something
see somebody do something→somebody +be +seen to do something
A girl saw my wallet drop when she passed by.→My wallet was seen to drop by a girl when she passed by.
The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss.
4、如果是接双宾语的动词改为被动语态时，直接宾语(物)作主语，那么动词后要用介词，这个介词是由与其搭配的动词决定。
He gave me a book.→A book was given to me by him. He showed me a ticket.→A ticket was shown to me by him. My father bought me a new bike. →A new bike was bought
for me by my father.
5、一些动词短语用于被动语态时，动词短语应当看作一个整体，而不能丢掉其中的介词或副词。
We can't laugh him. →He can't be laugh by us.
He listens to the radio every day. →The radio is listened to by him every day.
The nurse is taking care of the sick man. →The sick man is being taken care of by the nurse.
