求助紫皮OG语法第17题

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

答案是B,其中，这里rising是作名词使用吗？我查过词典，里面讲rising是形容词，怎么回事？

这里rising 是动名词。

我的理解是,doing形式的词究竟是什么词性,要结合它前面的词来判断:

比如:如果一个短语以rising开头,或者是介词+rising,这时的rising可能是分词形式.

如果是the/a + rising, 那么rising是动名词.

如果是be+rising,那么就是进行时.
