Jean Wagner's most enduring contribution to the study of Afro-American poetry is his insistence that it ____ in a religious, as well as worldly, frame of reference. A. is to be analyzed B. has been analyzed C. be analyzed D. should have been analyzed(全国研考,94-6)
答案为 C(be analyzed)。但我弄不懂为什么答案为 C。
词典解答
insistence 后的向位语从句中要求使用现在时虚拟式。在英国英语中则人都使用 should + 动词原形，如： Despite Teabing's insistence that their investigation should be conducted meticulously, Sophie felt eager and pushed ahead of them, making a cursory walk-through of the five knights on the left. (Dan Brown, The Da Vinci Code) 尽管提彬坚持调查要小心行事，索菲还是急不可耐地跑到他们前面，匆忙把左边五尊骑士石像打量了一遍。（《达·芬奇密码》）见 insist, requirement。
