同位语从句可以用which引导吗

大家知道，在定语从句中，若先行词为指事物的名词，有时既可用that来引导定语从句，也可用which来引导定语从句，但在同位语从句中，习惯上要用that，而不用which。如：

我坚信他会获胜。

误：I hold a firm belief which he will win.

正：I hold a firm belief that he will win.

我得出结论这样做是不明智的。

误：I've come to the conclusion which it was unwise to do that.

正：I've come to the conclusion that it was unwise to do that.

同位语从句可以用what引导吗

what不能用于引导定语从句，但可以引导同位语从句，尤其用于idea之后。如：

Have you any idea what time it starts? 你知道什么时候开始吗?

I didn’t have the faintest idea what you meant. 我一点也不明白你是什么意思。

Do you have any idea what it means to be poor? 你知道贫穷意味着什么吗?
