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
为什么B选项不用separate和required之间不用加and呢?不是并列的意思吗?
谢谢! |
