单选题
Joe had many regrets when he ______ the years he spent abroad. A. looked back on B. looked down upon C. looked up to D. looked out of
【正确答案】
A
【答案解析】[解析] 本题考查对固定动词词组的掌握，选项A中的look back on(回忆，回想起)与题意相符，故为正确答案。 [避错指南] 考生要注意平时的积累，清楚区分各词组的意思。选项B(1ook down upon)意为“蔑视，瞧不起”；选项C(look up to)意为“尊敬，仰望”；选项D(look out of)意为“从……向外看”，三个选项放在题目中都不通顺，故应排除。
