Question

We all know that, ______, the situation will get worse.

1. A.
   not if dealt carefully with
2. B.
   if not carefully dealt with
3. C.
   if dealt not carefully with
4. D.
   not if carefully dealt with

Answer 1

B
思路分析：空白处是一个状语从句简化成的分词短语用作状语。它可还原成if the situation it not carefully dealt with，省考主语the situation（因与主句主语一致）和be动词is，便成为正确的分词形式，故B项结构正确。
【点评】该题考查分词作状语。偏难。分词作状语时首先要求分词的逻辑主语和句子的主语要一致，当分词表示的动作与主语之间为主谓关系时，用现在分词，为动宾关系时用过去分词，考生应牢记这一规则。
