OG-37, 为是么不能用IF

bobiouou

15. While some academicians believe that business ethics should be integrated into every business course, others say that students will take ethics seriously only if it would be taught as a separately required course.

(A) only if it would be taught as a separately required course

(B) only if it is taught as a separate, required course

(C) if it is taught only as a course required separately

(D) if it was taught only as a separate and required course

(E) if it would only be taught as a required course, separately

我还是不明白C 错在哪里，IF也可以解释为只要啊, 是不是ONLY 放在 AS 前面错了?

请NN指教. 谢谢

1，注意形容词是否是并列意义的形容词。比如，physical and mental health, significant scientific research

2,修饰词的修士对象，修饰名词，动词还是修饰形容词。

3， only 的位置

only if和if是不同的两个概念.

若死记, 就记住语法题中, only,first等词的位置不可以随便改变,除非逻辑关系强烈要求.

若理解, only if是必要条件指示词, 而if是充分条件指示词. 逻辑题中更加要用到.

个人理解.
