题目

“Are you satisfied with his answer?” “Not at all. It couldn’t have been ____.” A. better                                                   B. worse C. more                                                    D. less 答案：B 解析: 此题关键是要理解 Not at all 的意思。根据上文语境，Not at all 为 I am not satisfied at all with his answer 之省略，即表示“我对他的回答一点也不满意”，既然如此，他的回答当然会是 It couldn’t have been worse（不可能更糟）。
