Is oxgen the only gas __A_____helps fire burn?
A that B \ C which D it
that引导的同位语从句

I 'll tell you ___C__he told me last week.
A all which B all what C that all D all

that all=what

第一个 that,选A 因为有only 像 only,very,这一类的词,后面只能用that.
第二个 我觉得是 all that,既然没有 我觉得 B比较合适
相当于 i will tell you all the things he told me last night.
二楼肯定是错的,all这种符合不定代词后面只能用that,绝不可能用which.

A and B (我会告诉你所有他上周所告诉我的一切)
