希望能得到详细一点的解释 It was not dark ____ (when/that)until he found ______ (what/that) was the best way to solve the problem. 不能这样理解么——he found (that was the best way to solve the problem.)他found的是一个句子啊~或者——that 强调而 what不强调~
It was not dark until he found what was the best way to solve the problem. 直到天黑了他才找着最好的解决问题的办法. 第一个空不用填,第二个填what,因为原句里强调的并不是哪一个才是最佳解题方法,而是强调他花了多长时间才找着了最佳解题方法.
