单选题 Dave: It's important to understand that it's not too late. ______ and think that you have no chance of success. Paul: It's still not too late? All my hopes were dashed by the announcement. Dave: You need to remain alert, especially in a crisis.

A、 Don't go to the wall without hesitation
B、 You must not simply throw in the towel at this Stage
C、 Never put your back into it immediately
D、 There may be a dramatic change in no time

【正确答案】 B

【答案解析】对话中大卫指出，现在重要的是知道一切还来得及，并告诉对方在危机中尤其需要保持警觉。因此B项“你不能在这个阶段认输”符合语境。throw in the towel认输。go to the wall失败。put your back into埋头干。
