选择题
The police are to ______ the traffic accident that we don’t know _____.
A．dealing with; how to deal with
B．deal with; how to deal with
C．deal with; how to do with
D．do with; what to deal with
答案
答案：B
题目分析：考查短语辨析。be to do sth可以表示安排、计划做某事，排除A，deal不及物，因此deal with与how连用，do with与what连用，what作do的宾语，排除C、D；故选B。
