答案

把主动语态改为被动语态,可以遵循以下几个步骤：
1. 把宾语变成被动语态中的主语；
2. 找出谓语动词,变成相应的被动.如：一般式变成be done.过去式变成was/were done；
3. 把主语变成介词by 的宾语；
4. 注意人称、时态和数的变化.
例：1. Bruce writes a letter every week. →A letter is written by Bruce every week.
2. Li Lei mended the broken bike this morning.→The broken bike was mended by Li Lei this morning.
