问题解答：

我来补答

1.【compounded(是动词?还是过去分词做状语?如何区分呢?) 】
是动词,有很多原因.首先,这句话主语在前面而且用逗号隔开了,在compounded这小句里面没有主语,如果它是过去分词作状语,那它用来修饰谁呢?再者,如果它是过去分词作状语的话,那它相当于一个形容词,从意思上看,副词 frequently 修饰形容词 compounded ,意思是“频繁地混合的”.再退一步说,如果说 frequently compounded 是本文里合理的形容词这个说法说得过去,那接上后文,怎么又不通了呢?答案只有一个,【compounded是动词的过去时】
2.选项A的话,“the treatment and release of……”解释的是上述的“problem”“为什么会出现”.而选D的话,“the treatment and release of……”解释的是“为什么出现在”“这个area”.一个强调原因,一个则侧重地点.
【网上找不到解析,全都是自己打出来的.我也在准备sat,呵呵,欢迎追问,望采纳!】
