Lily doesn’t know she and her friends can do to help the little boy parents have left their hometown for making money.
A. that; whose
B. how; who
C. what; who
D. what; whose

A. that; whoseB. how; whoC. what; who(答案→)D. what; whose解析：that引导宾语从句一般不充当句子成分，只起连接作用；how引导宾语从句，一般做方式状语；what引导宾语从句，做从句的逻辑主语或者宾语。句意：莉莉不知道她和她的朋友们能做什么来帮助这个小男孩，他的父母离开家乡去挣钱了。结合语境可知前文是宾语从句，what，什么，充当宾语从句谓语动词do的逻辑宾语。下文为定语从句，the little 宾语boy和parents是逻辑上的所有关系，故引导词用whose，选D。
