拜托语法高人帮我看看啊，谢谢

请教一下：

这道题E是不是少了一个that,比较的不是人数吗？为什么是对的？

1.       According to a study by the Carnegie Foundation for the Advancement of Teaching, companies in the United States are providing job training and general education for nearly eight million people, about equivalent to the enrollment of the nation’s four-year colleges and universities.

(A) equivalent to the enrollment of

(B) the equivalent of those enrolled in

(C) equal to those who are enrolled in

(D) as many as the enrollment of（E）

(E) as many as are enrolled in



第二道题我想问一下： producing放的位置是不是只能形容vapor从而不正确吗？如果to produce是不是形容那个reaction的，感觉咯哩八嗦的，Acid rain and snow resulf from the chemical reactions between A and B to product corrosive sulfuric and nitric acids

2.       Acid rain and snow result from the chemical reactions between industrial emissions of sulfur dioxide and nitrogen oxides with atmospheric water vapor to produce highly corrosive sulfuric and nitric acids.

(A) with atmospheric water vapor to produce highly corrosive sulfuric and nitric acids

(B) with atmospheric water vapor producing highly corrosive sulfuric and nitric acids

(C) and atmospheric water vapor which has produced highly corrosive sulfuric and nitric acids

(D) and atmospheric water vapor which have produced sulfuric and nitric acids which are highly corrosive（E）

(E) and atmospheric water vapor to produce highly corrosive sulfuric and nitric acids

这道题正确答案给的是D，不太明白为什么B不对

3.       Although dozens of New York’s small museums are either devoted to local history or various ethnic groups, there are many one-of-a-kind museums from Manhattan to the Bronx
that are open for exploration on summer weekends.


(A) Although dozens of New York’s small museums are either devoted to local history or various ethnic groups, there are

最后一个问题，想问问这道题C为什么不对啊，after也可以是介词啊，我记得做过一道题说一个公司利润增长了after falling three months，这里after直接就是接了一个v-ing的形式啊，谁能给我答疑一下啊

4.       Alaska

呵呵，太感谢你啦
一定要顶
我在NewYorkCity，在CD上混着都忘记时差了

虽然我的解释很烂，但是看在我这么晚答题的份上好歹也顶一个啊。。。

第二题，between A and B，排除A,B，D用复数HAVE 是跳跃修饰 reactions，reactions是 produce highly corrosive sulfuric and nitric acids的逻辑主语。
第三题，应该用并列关系，而不是转折关系。
第四题ITS是就近指代，A,D中的ITS指代economy ，逻辑不通，B中fund＝the intention，E中的they没有指代。
第一题，enrollment是800，或1000，不是800人，排除A,D。B的同位语表达不对，如果我不知道答案，我可能选C，但是equal和as many as 有区别，我举个例子Hunters kill many deers, as many as bears which were killed 1 month ago. Hunters kill many deers, equal to half of the deers in New York.
如果你选了equal，就表示这些人都注册了学校。。这题的解释是我猜的，不确定
