单选题 Alice was about to ______, when she suddenly found an answer to the question.
[A] make up [B] look up [C] turn up [D] give up

【正确答案】 D

【答案解析】[解析] 考查动词短语辨义和句意理解。四个选项都是短语动词：make up指“虚构，弥补，化妆”等义；look up指“向上看，尊敬，查寻”等义；turn up指“找到，发现，出现，突然发生”等义；give up指“放弃，停止，认输”等义。由空格后从句的补充说明可以推知．主句应指Alice(由于找不出答案而)打算“放弃”才符合逻辑，故应选give up。
