150 看了讨论还是不懂！

看了讨论还是不懂！OG说Choice E also employs the nonidiomatic rise of the moon.

可是字典上说rise有上升的意思呀！那个B有什么区别，都是一个动作：上升，望赐教！

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（B）

(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. 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.

"the rise of the moon" or "the moon rises", I think.

the former "rise" is a noun, and the latter is a verb.

If you don't use "the" in front of "rise", it seems that "rise" is a verb. So, E, rise of moon is not so good.

Do you think so?

还是记住mistake x for y 这个固定搭配，这才是ets的考点

一般说来有名词形式优于动名词，但是这里raising 也是一个名词，有上升的意思， 所以相对于rise不存在劣势。

主要通过mistake for 判断。

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
(C)The rising cost

answer is C. In choice A, The rising of costs is unidiomatic. 奇怪吧！

我的理解是：150题里面强调的是动作：把moon的rising当成了攻击。

52题，因为后面有个a growing opportunity，所以前面用The rising of costs和他平行。

rise n.

2.[singular] the achievement of importance,success, or power: [+of] "Citizen Kane" details the rise of a ruthless tycoon.

rise作名词是有上升的含义，但是它也有好几个意思，这个就是与of搭配时的Longman解释。
