答案：25.A 26 C 27D

我要详细的解说，谢谢！

Answer 1

25. B. of 才是正确答案。 “介词 of + 抽象名词 = 一个形容词”，这里的 of big benefit = very beneficial，非常有益处的。
26. both 两者都。因为前面说了 one or the other （一个或另一个），说明这里有且只有两个方法可供选择。全句意思是“不要非得选择这个或另一个，我们可以从这两个方法中同时受益”，也就是两个方法都用。
27. it is the first/second/third... time that sb. has done sth. 是一个固定句型，意思是“这是某人第一次/第二次/第三次等做某事”。“这是中国人第一次担任如此高级的联合国职位。”

希望我的解释正确。祝你进步！
