初中英语语法课件 The present continuous tense 现在进行时 概念:表示正在进行或发生的动作或状态的时态。 结构:由be动词的现在分词形式am/is/are + -ing构成。 现在进行时的标志性词语有now, look, at the moment, listen等 现在进行时的基本构成:主语+be动词+现在分词 They are drawing pictures. She is reading. 现在分词的构成规则 一般在动词词尾加-ing,如:read-reading 以不发音e结尾,去e加-ing,如:write-writing 以重读闭音节结尾的动词,末尾只有一个辅音字母,应先双写这一字母,再加-ing。 swim-swimming run-running cut-cutting shop-shopping sit-sitting 特殊变化:lie-lying平躺,die-dying死亡 动词后面加ing的几种形式 sleep stand sweep wash sleeping standing sweeping washing clean jump walk do cleaning jumping walking doing 记一记 running swim swimming run sit sitting dancing closing riding having 双写+ing 以动词闭音节结尾,且末尾只有一个辅音字母的,应双写此字母,再加 –ing dance close e+ing 动词末尾有不发音的e ,则去e加 -ing ride have 记一记 常用的现在分词 一般在动词原型后+ing 以不发音的e结尾的,去e,+ing 重读闭音节以一个辅音字母结尾的,双写这一字母+ing go ask talk write take live get run swim put shop going asking talking writing taking living geting running swimming putting shopping 口诀教你学doing 现在事情正发生,Look,listen,“看”和“听”。 句中常见“现在”now,动词结构be doing。 be有am,is,are,依据单、复和人称。 “三单”is,“我”am,其余用are要记清。 现在分词学会变,一般情况都+ing。 尾e无音就去掉,词尾ie变y形。 重闭音节辅元辅,尾辅双写立当中。 换方法心中记,现在进行时态明。 现在进行时的句式: 肯定句—主语+be+doing I am doing my homework. 否定句—主语+be+not+doing I am not doing my homework. 一般疑问句—be提到句首(注意人称变化) Are you doing your homework? 1. 表示现在正在进行的动作和发生的事 ---What are you doing? ---I am reading a book. 2. 有时表示现阶段正发生的事,但此刻动作不一定正在进行 He is teaching at the school. We are learning Unit5 these days. 基本用法 3. 现在进行时的句子中常有 now, 或在句首常出现 Look! Listen!等提示词 Listen! Danny is singing in the room. He is doing his homework now. 现在进行时的句型转化 肯定句转换成否定句,要在 be 后加 not 构成 We are reading English now. We are not reading English now. 陈述句转换成一般疑问句,把be动词提到句首 The student is playing.
