Question

【题目】Now Andy feels very worried because he doesn’t know _______.

A. what to do it B. what to do next

C. how to do D. how to do next

Answer 1

【答案】B

【解析】试题分析：句意：现在安迪感到非常担心因为他不知道下一步做什么。疑问词加动词不定式做宾语，how to do it为how加不定式构成的结构做宾语，或者用what to do做宾语，表示该做什么；next是时间状语，根据句意，可知缺少宾语，故填what to do，故选B。
