Question

It was not until dark _____...

It was not until dark ______ he found ______ he thought was the correct way to solve the problem. A．that; whatB．that; thatC．when; whatD．when; that

Answer 1

【答案】A 
【答案解析】试题分析：句意：直到天黑他才发现他想到的是解决问题的正确的方法。第一空填that，这是强调句，It
was
not
until
that…，第二空填what，在found后面的宾语从句中，what
he
thought是主语从句，主语从句中缺少主语，用what引导主语从句，选A。
考点：考查连词和宾语从句
