大家好，我是小科，我来为大家解答以上问题。when i was a kid疯狂动物城，when i was a kid很多人还不知道，现在让我们一起来看看吧！

1、When I was a kid,I liked playing computer. When I grew up,I found that it was really a waste of time.I should have used the time to learn some beneficial things.When I was still in the middle school,I was infatuated with cumputer playing.As I was too induldged in this hobby, my life was totally affected.这个 but only played 我觉得有点多余，所以省略了。

2、浪费时间短语我认为a waste of time更地道一些。

3、should have done是本应该做而没有做，所以这句话意思是我本该利用这些时间做些有意义的事（标明其实没有做，都用来玩了）最后我感觉你的意思是应为你过份沉迷与这个兴趣，致使你的生活完全受到了影响，就小小改了下说法。

4、希望对你有用，有问题欢迎继续探讨。

本文到此讲解完毕了，希望对大家有帮助。
