Researchers have been developing a more reliable method of ____ spent fuel from nuclear power station.

A. procession

D. processing

都是名詞為什麼不能選A呢

當然只看介系詞 of，會這麼想，但是空格後面還有內容哦：

(1) Researchers have been developing a more reliable method.

(2) ___ spent fuel from nuclear power station (spent 是形容詞，「用過的，不能再用的」)

眉角就在名詞 fuel，我們不會把兩個名詞這樣「procession fuel」兜在一起，而是用介系詞連接：

procession of spent fuel…

不過這接在 a…method of 後，實在太不乾脆，of 來 of 去。

所以只要把 (2) 當成獨立句，答案就豁然開朗了：

(1) Researchers have been developing a more reliable method.

(2a) Using this method, we can process spent fuel from nuclear power station.

只要把 2a 的動詞改成動名詞 processing，就可以放在介係詞 of 之後啦！

Tip:

下次再遇到這種句子，先找出空格後面的介系詞 (例如本句的 from) 或連接詞，提醒自己答案必須配合 of 和後面介系詞之間的所有內容：

…of ___ spent fuel from…
