Tom ____ better than to ask Dick for help. A. shall know B. shouldn't know C. has known D. should have known 正确答案:D 译文:汤姆本不至于笨到要去请迪克帮忙的程度. 解析:"主语＋should have known better（than to＋原形动词）",意为“本来不应该那样笨,而事实上却很笨去做了...”，是指已经做过的事。例如: I should have known better. 我本来不应该那样笨。 You should have known better than to talk like that. 你本不致于说出这样的话。 You should have known better than to go mountain climbing alone.你本来不该单独去爬山。
