___ we need water is quire clear
A That B What

A.
1.That we need water is quite clear.
that we need water是主语从句, that 在主语从句中不充当成分, 因为we 是主语need 是谓语, water 是宾语。
2。What we need is water.
what we need 是主语从句, what 在主语从句中充当宾语成分, we 是主语need 是谓语.
如何判断填that 还是what,要看需要什么成分, 切记:在引导主语从句/宾语从句/表语从句时,that 不充当成分, 而what 是充当主语/宾语/表语的。

A That
That we need water 是主语从句 由that引导

A
That指代的就是后面的we need water这个简单句子.而What放在句子中翻译也不通,从语法角度来说也不正确.

A
that 引导的主语从句啊!
that加句子可以做句子成分,比如主语,表语等等.

A
that指代的就是we need water 这件事情
而what这里没有指代的对象,如果没有"water",what 就可以用了,指代"water"

A.
That we need water is quite clear.
that we need water是主语从句, that 在主语从句中不充当成分, 因为we 是主语need 是谓语, water 是宾语。
