Question

As students，___full use we have made of our time to study，there's still room for improving．（　　）

A. whichever

B. whatever

C. though

D. however

Answer 1

答案是B．本题考查引导让步状语从句的引导词；whichever无论哪一个，强调选择；whatever无论什么；though虽然；however 无论如何；题干中需要的是修饰名词短语full use的形容词，however 是副词，排除；whichever表示"选择"，不符合语境；though引导从句时，只能做连词，不充当成分；whatever属于形容词性质，可修饰名词，故选B．
