His success was due to____he had been working hard all the time.

问题描述:

His success was due to____he had been working hard all the time.
His success was due to____he had been working hard all the time?that,the fact which,the fact that,the fact what选哪个,帮我分析下

一定是the fact that
分析:DUE TO STH 是“由于.”它不可直接跟THAT从句.而THE FACT这里相当于STH.后面的THAT是同位语从句,指代THE FACT的详细内容.
