Unit 5,Im cleaning my room.,Lesson27,“ing”的来历,相传很久很久以前有一个国王 (king)，他非常喜欢sing（唱歌），每天在王宫里唱呀唱的，连国家的事都扔在脑后不管，大臣们（ministers）都很着急，但又都没有办法。 有一天，这个国王照例在王宫里引吭高歌，这时一个外国使节有事想求见国王。大臣们进去禀报了几次，但是国王唱兴正浓，就是不出来接见。大臣们又不敢对外国使节说国王正在里面 sing，怕人家生气。正在大家不知怎么办时，有一个大臣想出了一个办法，他假装到里面去禀报国王，然后出来对外国使节说国王有急事，他正在里面 “ing“，今天不能接见。外国使节不知“ing“是怎么回事，只知道国王有急事，正在“ing“，又不便多问，只得怏怏离去。 从此以后，每当国王在唱歌，而又有人求见时，大臣们就用国王正在“ing“打发来者。久而久之，“ing“就成了国王正在做某事的代用词。来者只要一听说国王正在“ing“，就知道国王有事无法接见，便自动告退。 慢慢地这种说法流传到了民间，人们只要一说起某人正在做某事，便在动词原形后面加上ing。后来为了区别不同的人称，人们又在主语后面加上了be动词， 形成了“be + 现在分词(present participle)“形式的现在进行时态 (present coutinue tenses)。,1.含义：表示现在正在进行或一段时间正在进行的动作。 2.构成：be +V-ing,现在进行时的含义与构成,He is reading a book.,sing a song,play the violin,tell a story,play the guitar,What are we doing? 我们正在干什么？,We are having an English class now. 我们正在上英语课。,Im teaching English.我正在教英语。,Youre learning English.你们正在学英语。,Its 11 oclock now.,Is he ?,Whats he doing?,Is he ?,Is he ?,Whats he doing?,He is making a call.,Whats she donging?,She is singing a song .,She is telling a story.,What,s she doing?,Is she singing?,She is reading in the library.,What are you donging?,Im playing the guitar.,Im playing the voilin.,Whats he donging?,He is playing the guitar.,Is he playing the voilin?,Exercises,找一找，错在哪儿？ 1.
