that's _________I want to say.A.all what B.all C.which D.all which选哪个?为什么?
B.
all为定语从句的先行词,其后接的是that引导的定语从句,因that在定语从句中作say 的宾语,故可以省略.定语从句先行词为all时,定语从句只能用that引导,不能用which.

a

All.
如果选项里有What, 也对。
因为看起来顺眼，读起来顺口，听起来也顺耳。

B

选A，what做I want to say的宾语

应该选A WHAT I WANT TO SAY 是做ALL的表语从句

That's all I want to say
=That's all that I want to say.
=That's what I want to say.(what=the things that)

什么乱七八糟的 选B
要么你说 that's what i want to say 。要么说 that's all i want to say
