Though the law will require emissions testing of all diesel vehicles, from tractor trailers to excursion buses, it will have no effect on sport utility vehicles, almost all of which are gasoline powered, and will not be subjected to emissions-control standards as stringent as they are for diesel-powered vehicles.

A.      powered, and will not be subjected to emissions-control standards as

stringent as they are for

B.      powered, and therefore not subjected to emissions-control standards

that are as stringent as those of

C.     powered and therefore not subject to emissions-control standards

      as stringent as those for

D.     powered, which are not subject to emissions-control standards as

stringent as they are for

E.      powered and therefore they are not subject to emissions-control

standards as stringent as those of

正确答案是C，我选B

请求指导一下B错在哪里

两个黄字部分有什么差别呢?

动词不是尽量补出比较清楚吗?

谢谢

顶

B）错的原因是不是在於 and 只连结两件事，前面不需要打，

请您指教～谢谢

一般情况下that be都是省略的.

of表示属性,在这里不好

B..      powered and therefore not subject to emissions-control standards as stringent as those for

这里those 是指代sport vehicles吗？那for是什么？

B: (are) subjected to 中的are和are gasoline 中作用不同，好像不能省略；另 are subjected to 表示遭受或经历某事物，不妥

C: (are) subject to 中are和are gasoline 同是系动词，可省略；另are subject to 表示服从某事物或人，如are subject to law,因此 are subject to xx standard 可行

个人看法，请指正

b中that are

补出来与不补出来没有什么意义,

动词不是尽量补出比较清楚吗?  这是LZM的话,但也不一定适应在一切场合

B中错误powered, and therefore not subjected

应该为powered and therefore not subjected 或者powered, and therefore(某代词) not subjected

跟OG217 rivalry that develops between     作用一样,可省略可不省略,不影响意思

但省略更简洁,这是GMAT 的精神
