He did it one-third time it took meis this sentence right?

问题描述:

He did it one-third time it took me
is this sentence right?

错了,应该是
He did it one-third time OF it took me
他做完的时间是我的3分之1

应该是加个引导词 He did it one-third time句是个句子
后面的该用个that来衔接短语it took me
这样 句子就连贯
He did it one-third time that it took me
