Question

英语语法：It was not until dark that he found

It was not until dark that he found( )he believedwas the correct way to solve the problem
不是缺宾语么？怎么就不能用that?一定要用what?

Answer 1

从前面的句子来看是却宾语，但这里的代词还要做后面定语从句was the correct way to solve the problem的主语，这样就是能用可做主语的what而不能用that.

Answer 2

what一方面要做found的宾语，另一方面还充当着（）was the correct way to solve the problem的主语。he believed是插入语，可以不用管。对于that，则不能在当宾语的同时还当主语。

Answer 3

what he believed was the correct way to solve the problem 整个句子作he found 的宾语从句，而what he believed 是这个宾语从句的主语。只能用 what

Answer 4

what he believed 是用what引导的宾语从句，what= all that,通常翻译成所-----。如： What i need is money.我所需要的是钱。

Answer 5

是的，要用what才通顺
