While all states face similar industrial waste problems, the predominating industries and the regulatory environment of the states obviously determines the types and amounts of waste produced, as well as the cost of disposal.
(A) all states face similar industrial waste problems, the predominating industries and the regulatory environment of the states obviously determines
(B) each state faces a similar industrial waste problem, their predominant industries and regulatory environment obviously determine
(C) all states face a similar industrial waste problem; their predominating industries and regulatory environment obviously determines
(D) each state faces similar industrial waste problems, the predominant industries and the regulatory environment of each state obviously determines
(E) all states face similar industrial waste problems, the predominant industries and the regulatory environment of each state obviously determine
我做这道题事用agreement和句义解题，首先用agreement排除A、C、D，然后while引导的从句与主句之间需要体现转折关系，表达出all states的统一情况与each state的具体情况之间的对比，B选项中each state faces a similar industrial waste problem说的是每个州要面对类似的问题，每个州自己怎么similar？因此不如原句的all states face similar industrial waste problems合理，既然原句的这个部分没有问题就不需要变动，可以确定选E。
OG对这道题考点的解释Agreement; Grammatical construction，agreement很明显，但是个人觉得grammatical construction在这道题中没有什么大作用，求解惑，先对any 答复表示感谢~~作者: saintaa 时间: 2013-3-11 21:36
