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 sub-

jected 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

                              Answer:c

mine is e.

顶。。。我选了A。。大牛帮忙分析一下结构

我也选e，关于最后的for, of用法怎么区别？

of 與 for 語意不同。

舉個例子:

A. standards of the students 那些學生的水準

B. standards for the students 為那些學生設的標準

以此類推，不難理解此題的答案了!

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

stringent as they are for

整个作定语从句，但在该从句中they指代sport utility vehicles，意思上不合逻辑。

A后面的they的确是指代不明。

另外还有一点是：subject to 与be subjected to的区分。

subject to: A is subject to B...: A is under the power or authority of B..

be subjected to: A is subjected to B: disposed....
