Question

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

A．that; what	B．that; that
C．when; what	D．when; that

Answer 1

A

試題分析：考查復雜句：第一空是not until 用于強調句，構成it is not until·····that  “直到····才”
第二空后的he thought是插入語，將he thought刪掉后會形成這樣一個句子：he found ____ was the correct way to solve the problem.句中的主語和謂語分別是he, found，因此橫線上的詞要引導一個賓語從句。分析賓語從句的句子成分就會發(fā)現(xiàn)，賓語從句的主語缺失，只能用what來充當主語，that在名詞性從句中不充當成分。句意：直到天黑他才發(fā)現(xiàn)他所想的是解決問題的正確的方法。選A。
