1.She is often heard to sing the song.
hear sb do sth.变为被动语时需要加上to,变成sb+be+heard to do sth.
2.We are taught English by Miss Ding.
3.这本身就已经是一个被动语态了啦.主动语态是:My parents influence me.
4.When were these cars made by them?
5.A new big school will be built by us in two years.
6.这也已经是一个被动语态了.主动应变为:They have sent up three man-made satellites into space.
7.The computer was turned on by him an hour ago.
turn在这个句子是实义动词,而不是系动词.它和on构成短语,表示“打开”,故有被动语态.
8.A thief was seen rushing out of the shop by the police man.
9.My brother has been written to by my father.
write to sb,“给某人写信”.write to是一个整体,介词to 在变为被动语态时不能省略.
