题目内容
9.用筷子指着别人是不礼貌的.It's impolite to point at others with your chopsticks.
分析 It's impolite to point at.
解答 答案:It's impolite to point at.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句型It's+adj+to do sth,其中it做形式主语,动词不定式做真正主语,不礼貌的impolite,指着某人point at sb,故答案是It's impolite to point at.
点评 It+be+形容词+(for sb.)+动词不定式 这类句型常用形容词easy,difficult,hard,important,possible,wise等作表语,有时候为了强调不定式动作的执行者,常在不定式前加for sb,如:It's necessary for the young to master two foreign language.It is unwise to give the children whatever they want.
