题目内容
8.Doing morning exercisesstays(stay) us healthy.分析 做晨练让我们保持健康.
解答 答案:stays.结合句意这里是说客观事实用一般现在时,句中的动名词短语Doing morning exercises是主语,谓语动词用单数,所给单词是stay动词保持某种状态,后加形容词healthy构成系表结构,其三单是stays,故答案是stays.
点评 动名词做主语往往表示经常性、习惯性的动作,在口语中也可以表示具体的动作,单个动名词短语做主语谓语动词用单数.如:
Talking mends no holes.空谈无济于事.
Working with you is a pleasure.和你一起工作是一种乐趣.
