It's impolite to point at others with your chopsticks．

Answer 1

分析 It's impolite to point at．

解答 答案：It's impolite to point at．這里是說(shuō)客觀事實(shí)用一般現(xiàn)在時(shí)，表示做某事是怎么樣的用句型It's+adj+to do sth，其中it做形式主語(yǔ)，動(dòng)詞不定式做真正主語(yǔ)，不禮貌的impolite，指著某人point at sb，故答案是It's impolite to point at．

點(diǎn)評(píng) It+be+形容詞+（for sb．）+動(dòng)詞不定式  這類句型常用形容詞easy，difficult，hard，important，possible，wise等作表語(yǔ)，有時(shí)候?yàn)榱藦?qiáng)調(diào)不定式動(dòng)作的執(zhí)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．
