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
题目分析: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。
