Much to my delight,when I got back into my office,I found all the lights in it____.

问题描述:

Much to my delight,when I got back into my office,I found all the lights in it____.
1.finished repairing
2.turning up
3.fixed up
4.going out
为什么选3不选别的

外国说东西的维修习惯有fix up这个词组,所以不用finished repairing 还有灯在这显然是被安装修理的,所以不用ing的方式.turn up只开灯 那与much to my delight,我很欣喜这个主题不太符合,go out 也是指灯熄灭了,也是与提议不符合.
