Experts warn that medical waste from hospitals,if____ properly,may contribute to spreading diseases.
选 A.not handled
根据句意:医疗垃圾如果不正确处理,将会传播疾病.
实际上是“被处理”,有被动关系,用过去分词为宜.
其实是if 从句的省略形式.It it was not handled properly,被动语态省略了系动词和主语就是过去分词的形式.
选A,这是it is not handled 的省略形式。
A 这题考的是if的省略,这句话的语序也进行了调整,一种我们较能理解的语序是Experts warn that medical waste from hospitalsmay contribute to spreading diseases,if (it is)not handled properly.
所以这题选A
