(单选题)

Words of encouragement create social capital as it makes the person who ______ feel a sense of worth and makes him or her a nicer, happier being.

A.has appreciated

B.is appreciating

C.is being appreciated

D.has been appreciated

参考答案：C

参考解析：

考查现在进行时的被动语态。句意：鼓励的话语创造了社会资本，因为它使被赏识的人感觉到一种价值感，使他或她成为一个更好、更快乐的人。分析句子成分可知，Words of encouragement create social capital为主句，as it makes the person who ______ feel a sense of worth and makes him or her a nicer, happier being在句中充当原因状语从句，who ______充当限制性定语从句修饰限定先行词the person，并且此处与谓语动词appreciate之间为被动关系，且无强调动词的持续性和影响性，故此处应填入“is being appreciated”。故选C。
