题目

They lost their way in the forest, and _______ made matters worse was that night began to fall. A. that B. it C. what D. which 答案：C 解析: 此题考查名词性从句。that,it和which都不能在句中作成分引导主语从句，排除A、B、D三项。题意为“他们在森林里迷路了，更糟糕的是天开始黑了”。汉语中的“更糟糕的” 可用worse still,to make matters worse,what made matters worse等表达。但worse still和to make matters worse一般用作状语，而what made matters 将方程5x-2y+12=0写成用含x的代数式表示y的形式 ．
