10.I thinkit's impolite to laugh at others(嘲笑别人不礼貌) when they make mistakes.(laugh)

分析 it's impolite to laugh at others.

解答 答案:it's impolite to laugh at others.这里是说客观事实用一般现在时,表示做某事是怎么样的,用It is adj to do sth,不礼貌的impolite,嘲笑用laugh at,故答案是it's impolite to laugh at others.

点评 这里是针对laugh短语进行考察,注意这里It is adj to do sth,的运用,其中it是形式主语,动词不定式是真正主语.
