以下是引用薰衣紫草在2004-12-3 5:48:00的发言： C E is wrong. In E, "well established" refers to mineral extraction rather than to "leaching", distorting the orginal meaning of the sentence. So is D. The orginal meaning is leaching was as early as..... B is obviously wrong! read it again. The first half of the sentence doesn't even have a vt. because "established" here should be passive --- was established. 语法服了紫草了...读来已有OG解释风范了.可惜自己又上ETS当了,竟然弃C选E.晕! -- by 会员 pebbles (2005/9/23 2:51:00)
