It was not until dark         he found that it was the correct way to solve the problem.

A．that

B．what

C．which

D．when

答案

A

解析

试题分析：考查强调句的特殊句型：It’s not until ….that…,直到…才…,值得注意的是not until不是在句首，后面不能倒装，句意：直到天黑他才知道这是解决问题的正确的办法。选A。
点评：It’s not until ….that…是强调句，不要和倒装句混淆起来，not until放在句首时，谓语用部分倒装。
