Question

【题目】The problem is _________ difficult ________ students can solve them.

A. so; and few B. so; that little

C. so; that few D. so; that a little

Answer 1

【答案】C

【解析】

试题分析：so……that……如此……以至于……；few很少，表示否定含义，修饰可数名词复数； little很少，表达否定含义，修饰不可数名词；a little一点，表达肯定含义，修饰不可数名词。句意：这些问题是这么难，以至于很少有学生能解决它们。本句中students为可数名词复数，故选C。
