选择题
Misunderstandings resulting from lack of social communication, if not ______ properly, may lead to serious problems．
A．handling
B．being handled
C．handled
D．to handle
答案
答案：C
考查if引导的条件状语从句的省略。If引导的条件状语从句，如果从句主语和主句主语一致，且含有be动词，这时可以把从句的主语和be动词省略。补充完整应是if misunderstandings are not handled properly,所以选C。
