the thing后面加that还是whichThe thing ___ matters is not whether you fail or not,but whether you try or not.

问题描述:

the thing后面加that还是which
The thing ___ matters is not whether you fail or not,but whether you try or not.

Which吧,从句缺主语,

that matters 是先行词thing 的定语从句,is not后面是由whether引导的两个并列表语从句.译为:事情的关键不是你是否成功而是你是否尝试努力了
