It was not until dark _____ he found _____ he thought was the correct way to solve the problem．

A．when; that

B．that; that

C．when; what

D．that; what

答案

D

解析

试题分析：考查复杂句：第一空填that， It it not until...that... 是强调句“直到...才”，第二空填what，引导主语从句：what he thought   “他所想的”   句意：直到天黑，他才发觉他刚才所想的解决问题的方法是正确的。选D。
点评：两个以上的从句构成的复杂句相对较难，但如果学会分析句子，也可以准确找出答案，平时的训练不可少。
