请问og150题 the rise of the moon

og说：Choice E also employs the nonidiomatic rise of the moon.

为什么？

150. In the mid-1960's a newly installed radar warning system mistook the rising of the moon as a massive missile attack by the Soviets.

(A)  rising of the moon as a massive missile attack by the Soviets

(B)   rising of the moon for a massive Soviet missile attack

(C)  moon rising to a massive missile attack by the Soviets

(D)  moon as it was rising for a massive Soviet missile attack

(E)   rise of the moon as a massive Soviet missile attack

Choice B is best because it alone correctly handles the idiom to mistake x for y. Though choice D manages the correct preposition, for, the phrase the moon as it was rising for is less efficient and precise than the phrasing of choice B: since rising functions as a verb in D, the phrase for a massive... attack now seems to modify rising rather than mistook.(状语引起的修饰歧义，理解不同造成一种新的歧义错误) Choice C incorrectly uses mistook... to, and choices A and E incorrectly use mistake ... as. Choice E also employs the nonidiomatic rise of the moon.

而og52却说(a) the rising of cost不好？

52. The rising of costs of data-processing operations at many financial institutions has created a growing opportunity for independent companies to provide these services more efficiently and at lower cost.

(A)   The rising of costs

(B)   Rising costs

(C)   The rising cost

(D)   Because the rising cost

(E)   Because of rising costs

C is the best choice. In choice A, The rising of costs is unidiomatic (rise 有名词，用rising当然会错), and in B costs... has lacks subject-verb agreement. Choices D and E produce sentence fragments since Because makes the clause subordinate rather than independent.

1.        感觉文中有大并列的感觉：the rising cost……a growing opportunity

hedayong：这两个例子看似相关，其实不是一回事的，og150是说"月亮的升起"，强调升起的动作。og52不管主语是"上升的成本"或"成本的上升"（这个我判断不出来，觉得逻辑上都可以，呵呵），通过下边的帖子也可以看出如果表达成本上升的话应该用：the rise in cost 比较好，表示数量的增长。这两个题目正好是相对的。个人意见请多指教！

我不理解的地方是d答案rise of the moon为什么不对啊，rise不是也可以作名词的么？是不是这里强调正在进行的动作？不是单单一个名词？请指点一下！谢谢。

看过以前的讨论了：http://forum.chasedream.com/dispbbs.asp?BoardID=23&ID=57732

我看了一下longman，rise作为名词后面跟in， of ，to得情况都有。具体如下：

1）SUCCESS/POWER an increase in number, amount or value：

the rise of fascism in Italy

2）INCREASE [singular] the achievement of importance, success or power：

rise in costs/prices/taxes

3）give rise to sth especially written to be the reason why something, especially something bad or unpleasant happens

所以由此可以看出来，rise作为名词的时候没有动作上升的意思，所以要是强调动作的上升的时候要用动词的ing形式。

不知我的看法是否正确，请指教！

moon 的上升是持續性的，所以改rise為rising是看來好一點

至於the rising cost, 我個人認為是簡潔考慮

since rising functions as a verb in D, the phrase for a massive... attack now seems to modify rising rather than mistook.(状语引起的修饰歧义，理解不同造成一种新的歧义错误

为什么说for无法有效修饰mistook？似乎没有哪条规定说for是就近修饰，指向rising吧？

The rising cost of data-processing operations at many financial institutions has created a growing opportunity for independent companies to provide these services more efficiently and at lower cost.

"has" acts as a verb for  "cost". That is why I choose answer C
