请教大家一个关于逗号的问题,是OG小鱼版中第37题: 37. 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 答案中 a separate, required course不是很理解,两个形容词修饰一个名词我们见的不少,比如a tall and heave man等等,为什么要加逗号呢?而且我看了语法中逗号的用法,当三个以上的形容词修饰的时候才可以用逗号分开。还请高人指点一下。谢谢了。 |
