在家中哪个房间最重要?为啥?(用英语回答,说理由要详尽)

Bedroom, I would say. One has to spend most of the time there, at least 1/3 of your life. Also, without a good sleep, one cannot do anything more efficently, whether work or study. Third, for a couple, spend time in bedroom is a very important part for their relation and family... hehehe...

KITCHEN is the most important one, you can sleep on the floor of kitchen and do your need in the kitchen, but in the other places, you can't cook...

The bedroom is the most important, because you can get the best sexual experience there.
