My father( )in the factory since it ( )in 1956.
A.worked,opened

C.had worked,opened
D.has worked.had opened
商店开业（open）无须用被动语态,即has been open为什么选项的open全加ed
-（ ）you( )the text yet?
-Yes,we( )it two hours ago.
yet不是用现在完成时吗?
This kind of shoes( )well.All the shoes( )out.
A.sell,have sold
B.are sold,have sold
C.sells,have been sold
D.is sold,have been sold
我知道sell是主动表被动,但为什么第二空是have been sold?
如果是一般过去时的被动语态，应该是The door was open而不是The door was opened吧？

答案

1.在我们的日常生活中扮演着重要的角色.
2.这里的open是过去式.
3.三个空依次为 have,read,read``有明确的过去时间标志“two hours ago”因此用过去时态
4.sell well表示畅销的意思,第二个空强调已经被卖完了,这个记住就行了
