I don't think you should do that until ____another jobyou've found为什么用完成时?怎么分析的?

问题描述:

I don't think you should do that until ____another job
you've found
为什么用完成时?怎么分析的?

主句用将来时,until引导的从句用一般现在时或现在完成时。
不明可再问。

until表明了动作的先后,找工作在前,完成“找工作”,才能“do that”,那么自然是完成时啦~

其实,语法上
until you found another job

until you have found another job
都是对的
但为了强调先后,用have found就比较明确
