题目内容
14．It _____him 30minutes ________ his homework every day．（ ）| A． | took，to do | B． | takes，doing | C． | takes，to do |
分析 他每天花30分钟做作业．
解答 答案：C
根据题干中的关键部分It _____him 30minutes ________ his homework 并结合选项可知此句应用固定句型：It takes sb some time to do sth"花费某人多长时间做某事"，此句是指：他每天花30分钟做作业．根据时间状语 every day，可知此句为一般现在时，所以take需用三单形式takes，套用句型，故选C
点评 实义动词的第三人称单数．通常用于一般现在时态，要结合主语的单复数变化，选择合适的实义动词形式，注意实义动词第三人称单数变化规则．此题还要和固定句型联系起来．
