单选题 We are aware that______, the situation will get worse.

A、 if not dealing with carefully
B、 if dealt not carefully with
C、 if not carefully dealt with
D、 if not carefully dealing with

【正确答案】 C

【答案解析】解析：本题考查状语从句的省略。本句中that从句里面前半部分是条件状语从句，当条件状语从句、让步状语从句、时间状语从句的主语与主句的主语相同，且谓语部分含有系动词时，状语从句的主语与系动词可以同时省略；本句的条件句相当于if the situation is notdealt with，the situation…从句意看situation与deal with之间是被动关系，因此选项C正确。
