题目内容
9．He often _____English with the foreign teachers．（ ）| A． | practice speak | B． | practices speak | ||
| C． | practice speaking | D． | practices speaking |
分析 他经常和外教练习说英语．
解答 答案：D
结合题干及选项，可知此处考查了practice doing sth"练习做某事"的固定表达，所以把AB先排除；根据often，可知时态为一般现在时，主语为三单he，所以动词也应用其三单形式为practices，故排除C．故选D
点评 本题考查固定短语的用法，抓住句中的关键词并联系相关的语法知识可得出正确的答案．平时注意对此类短语或句式用法的总结与归纳．
