Question

---Hi. Lucy! What’s wrong with you? You look so worried.
---I have many problems to solve, but I don’t know ___________ first.

A．how to deal with

B．when to deal with

C．what to deal with

D．how to do with

Answer 1

C

试题分析：deal with处理，不定式短语中缺少逻辑宾语，故选C，做什么。How和when不能做宾语，只能做状语。
点评：how怎样，多用来做方式状语；when什么时候。多用来做时间状语；what什么，可做主语，宾语表语。无论是宾语从句还是不定式短语都需要一定的逻辑上句子成分，缺少了这一项就要用相应的词语来补上。
