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
答案是c，但是我记得XDF说过those单独出现时错的，可以帮我解答下这个问题吗》？谢谢 作者: biantaishabi 时间: 2009-12-25 09:51
不知道those单独出现是什么意思作者: running2k 时间: 2009-12-25 11:01
standards as stringent as those for diesel cars.... as ... as 前后应该一致啊。这个those 就是指代stardards for Diesel cars。没有问题。不明白你说的什么those的单独出现原则，除非是绝对的语法原则和固定搭配，xdf的解题技巧只是基于题目的总结，不一定是绝对对的。所以还是应该批判的继承吧。作者: pmyaoming 时间: 2009-12-25 11:09
Those here replace the standers.
A. The subject is not the "law" but the sports vehicles. The "they" can used to replace the vehicles and the standers, and so it is confusing.
B. The same mistake of subject as I said in option "A". The "those of " is wrong bc the abscence of the same form appeared before.
D.The which is wrong. And "They are" is confusing.
E. The "they " is redundant bc in first sentence there is a which. In terms of the use of the " those of ", there is not N+of in the sentence.作者: kun861010 时间: 2009-12-25 14:26
我想问的是，你们是怎么判断those是有指代还是没有指代的呢？因为如果是往前寻找复数名词，我们可能会找到2个复数名词，这个时候的those还是正确的嘛？
