单选题 She has no idea of what the novel is about. She ______ the novel.
  • A. mustn't have read
  • B. needn't have read
  • C. couldn't have read
  • D. wouldn't have read
【正确答案】 C
【答案解析】[解析] 句意:他对这本小说的内容一无所知。他不可能读过这本小说。本题考查情态动词的用法。做好本题的关键是要明白前面一句话的意思,前面说“他对这本小说一无所知”,说明他根本没有看过这本小说,所以后面对“没有看小说”的结果做的是肯定推测“could+have done”的否定形式,故C为正确答案。
