as能否引导定语从句？

mysoulfree

在做prep语法的时候碰到的一个题目
83. (29013-!-item-!-188;#058&003802)
Stock levels for domestic crude oil are far lower than in past years, leaving domestic oil prices vulnerable to any hints of oil supplies being disrupted in the Middle East or to any unexpected consumer demand growth possibly prompted by colder-than-normal temperatures.
(A) leaving domestic oil prices vulnerable to any hints of oil supplies being disrupted in the Middle East or to any unexpected consumer demand growth possibly
(B) leaving domestic oil prices vulnerable to any hints of oil supply disruptions in the Middle East or any unexpected growth in consumer demand that might be
(C) leaving domestic oil prices vulnerable to any hints of oil supplies that are disrupted in the Middle East or to any unexpected growth in consumer demand as was possibly
(D) resulting in the fact that domestic oil prices are vulnerable to any hints of oil supplies being disrupted in the Middle East or to any unexpected consumer demand growth possibly
(E) resulting in the fact of domestic oil prices that are vulnerable to any hints of oil supply disruptions in the Middle East or to any unexpected growth in consumer demand that might be
正确答案是B，我选的是C
但语法笔记中对于C的解释只是简单的说(C) as不能作为关系代词引导定语从句。。。 然后我查了一些题目有看到过AS引导定语从句啊。。。

希望大牛能为我解惑~~~ 谢啦！

很明显要对比各个选项，C选项额：that are disrupted，看到这个就应该有感觉没有B选项concise，当然as的使用咱再来看，这里是定语从句要修饰名词demand，用that might be prompted by colder-than-normal temperatures很明确的that从句作定语修饰demand，而as引导限定定从时需要和 such、 the same 连用，单独使用只能引导非限从句，很明确了选择B

got it ~~~ 顿悟呐！tks vm!
不过对于那个concise与否的问题还是好难把握哦。。。请问有没有一个比较常用的经验总结？

viviansecret

没有这种总结，只能说是not prefer，在两个选项无其他差异时，那含有这种that be+ved/adj/ving等的选项就不是我们要选择的，这种东西非绝对错误，但是实在看不出来别的split就只能走这种concise路线了

简单一点说吧~
这句话中 leaving domestic oil prices vulnerable to any hints of oil supplies that are disrupted in the Middle East 的that后面的都是修饰supplies，但是vulnerable的原因是hints of disruption,不是hints of supplies~，所以这里不能用定从~
不知道讲的清不清楚~
