Answer 1

Joy in living comes from having fine emotions, trusting them, giving them the freedom of a bird in the open.

Answer 2

1. 动作承受者（宾语）变为主语；
   

2. 动词用be+过去分词，时态要与主动语态一致；

Answer 3

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.
3. He has written two novels so far.→Two novels have been written by him so far.
4. They will plant ten trees tomorrow.→Ten trees will be planted by them tomorrow.
5. Lucy is writing a letter now.→A letter is being written by Lucy now.
6. You must lock the door when you leave.→the door must be locked when you leave.
