这句话是这样的:the monetary and social costs of allowing the conditions that creat acid rain to continue are potentially very great,AS ARE the costs of available processess to remove the sulfur and nitrogen oxides at the source,before they enter the air.
不懂的就是已用大写标出的“as are”,主语是谁?求大侠帮忙把这个句子还原成两个完整句子,这样更清楚理解“AS ARE ”的主语是谁~
这句话的两层意思:
1、the monetary and social costs(主语) of allowing the conditions that creat acid rain to continue are potentially very great
2、the costs (主语)of available processess to remove the sulfur and nitrogen oxides at the source,before they enter the air are potentially very great
注意,都有are potentially very great,用as来引导从句,并且谓语are前置倒装,就成了楼主的句子
所以主句主语是costs.从句主语也是costs,当然of后面修饰不一样,是不同的代价
再问: 这个语法的之下,如果我想省略第二个“potentially very great”, 还要表达出这个意思的话,ARE 就一定要前置了,对吗?
