当before、if、when、until、unless等引导的状语从句主从句主语一致的时候，从句的主语可以省略，省略原则是当从句谓语中包含be动词时，可以省略从句主语和be动词，保留be之后的部分，被保留部分常为现在分词、不定式、过去分词、形容词等。
在此句中，完全结构是：if the pollution is not carefully dealt with，在省略之后应该选择C，否定词放在分词之前。
考点：考查状语从句的省略2．A解析：A【解析】考查非谓语动词的用法。
句意：老板让Ｔｉｍ去弄清楚是否还有其他人缺席，ａｎｄ前后并列，前面是动词不定式ｔｏｇｏ，此处要省略动词不定式ｔｏ，故此处用动词不定式ｆｉｎｄ。
故选Ａ。
3．C解析：C【解析】【分析】【详解】考查非谓语动词。
句意：如果以米测量，我们的房间量起来八米宽。
第一空measure为系动词，意为“量起来”；第二空考查非谓语动词，逻辑主语Our bedroom与动词measure为被动关系，故用过去分词作状语。
故选C。
4．C解析：C【解析】【分析】【详解】考查非谓语动词。
句意：如果再给他做同样的治疗，他一定会痊愈的。
分析句子可知，if 从句的逻辑主语是he， he与动词give二者是被动关系，表被动要用过去分词，因此C项符合题意，D项表示正在进行，不符合题意，故选C项。
5．C解析：C【解析】【详解】考查连词+过去分词。
