Answer 1

1.His clothes are being washed.
2.This song is liked by everyone.
3.A lecture will be given to us by him this afternoon.
4.The room has been cleaned by us.
5.His younger sister was taken care of by Tom yesterday.
6.This work can be finished by them on time.

这种题只要搞清楚动词的被动形态，然后将句子的主宾颠倒过来就行了。中间就用该动词的被动形态连接。通常是 be ~~~ed.

Answer 2

第一道是is being washed ，这是一道进行时的被动语态
第二道是is liked,这是一道一般现在时的被动语态
第三道是will be given to ,这是一道将来时态的
第四道是has been cleaned ，这是现在完成时态的
第五道是was taken care of ，这是一般过去时态的
第六道是can be finished，这是含有情态动词的
被动语态里一定少不了be 动词和动词的过去分词，然后再根据不同的时态加入表示不同时态的助动词就可以了。

Answer 3

1.are being washed
2.is liked
3.will be given by
4.has been cleaned
5.was taken care of
6.can be finished

总之，被动语态中，进行时：be being done
完成时：have(has) been done
过去时：was(were) done
将来时：will be done
