问题描述:

the reason ( )he was late yesterday for class was ( )his mother was ill.
A.that,that B.why,why C.why,that D.that,why

必须是C、

A.that,that

选择C
The reason 【why】he was late yesterday for class was 【that】his mother was ill.
他上课迟到的原因就是他妈妈生病了.
The reason why.is that.什么的原因是.
why引导原因状语从句,that~引导表语从句.

C。与The reason why he didn't go was that he was ill yesterday。一样
希望采纳
