他的自行车修好了吗？

1．表示被动的动作在说话之前已经完成，强调过去的动作对现在造成的影响或产生的结果，通常与already，yet，never，recently等副词及时间状语so far，by now，up till now，since 等连用。
The room has already been cleaned．
这个房间已经被打扫干净了。
(现在已经不用打扫房间了)

据说已经调查了这个问题。
4．只带有一个宾语的动词变为被动语态时，将主动语态的宾语变为被动语态的主语。
We have built many houses in the past ten years．
→Many houses have been built in the past ten years．
5．带有双宾语的动词，如give，send，bring，take，teach，show，tell，make，sing，write，read，sell，buy，tell，pay，lend，pass，promise等，变为被动语态时，可将其中一个宾语变为主语，另一个保留不动。
We have given him the book．
→He has been given the book．
→The book has been given to him．
6．带有复合宾语的动词变为被动语态时，只能将宾语变为主语，原来的宾补改为主语补足语。
原来省略to的不定式作宾补的，被动语态中要用带to的不定式。
I have told them to help you．
→They have been told to help you．。
