As your instructor advised ,you ought to spend your time on something ______researching into .
A. precious
B. worth
C. worthy
D. valuable
题目解答
答案
B. worth
解析
本题考查形容词与动名词的搭配。关键点在于掌握worth, worthy, precious, valuable等词的用法区别。worth doing表示“值得做某事”,是固定搭配;而worthy需与of being done或to be done连用,其他选项通常修饰名词,不直接跟动名词。
选项分析
A. precious
Precious意为“宝贵的”,通常修饰名词(如precious time),但不能直接跟动名词,因此不符合题意。
B. worth
Worth doing是固定搭配,表示“值得做某事”(如This book is worth reading)。本题中something worth researching into符合语法,正确。
C. worthy
Worthy需与of being done或to be done连用(如The story is worthy of being told)。题目中缺少of,因此worthy不适用。
D. valuable
Valuable意为“有价值的”,与precious类似,修饰名词而非动名词,故排除。
