1、现在分词的变化规则1. 一般情况下,在动词后加-ing构成: workworking 工作 sleepsleeping 睡 waitwaiting等待 studystudying 学习 readreading 读 talktalking 谈话 2. 不发音的-e结尾的动词去掉e后再加-ing: smilesmiling 微笑 movemoving writewriting 写 come-coming leave -leaving take -taking bite -biting have having wake-waking make-making dance-dancing ride-ri

2、ding但是,若是发音的e结尾,则不能去e: seeseeing 看见 agreeagreeing 同意 3. 以重读闭音节或r音节结尾且末尾只有一个辅音字母动词,要双写末尾的辅音字母再加-ing: sitsitting planplanning preferpreferring run -running swim -swimming shop -shopping begin -beginning stop-stoppingforget-forgetting cut-cutting get-getting hithitting set-setting fit-fitting digdiggin

3、g重读闭音节是指:这个动词是重读音节,同时单词的最后也是以辅音字母结尾的闭音节。音节:1.单音节:音标中含有一个元音;(单音节全是省略了重读符号的重音节)2.双音节:音标中含有二个元音;(会有重读符号标在某个需重读的音节前)3.多音节:音标中含有三个或三个以上的元音音标。(会有重读符号标在某个需重读的音节前)音节:1开音节1)以发音的元音字母结尾的单节。例:be,he。2)以辅音字母(r除外)+不发音的e结尾的音节。例:make,like。*在重读的开音节中元音字母按字母名称读音。2闭音节以一个或几个辅音字母(r除外)结尾而中间只有一个元音字母的音节,称为闭音节。例:map,desk,is。*

4、在重读的闭音节中元音字母读做短元音。重读闭音节要判断一个单词是否是重读闭音节,必须同时满足下列三个条件:、这个音节必须重读;、这个单词结尾必须是“辅元辅”,即“辅音字母元音字母辅音字母”;、在这个“辅元辅”中的元音字母必须发短音。只有这三个条件同时成立的情况下,这个单词才能算是重读闭音节。如:put,dig 思考:listen play4. 以字母ie结尾的动词,通常将ie改为y,再加ing: diedying 死 lielying 躺 tie-tying 系住【注】 以字母l结尾动词,若末尾一个音节为重读音节,则必须双写l再加ing,如control / controlling,但若末尾一个

5、音节为非重读音节,则可双写l(英国英语)或不双写l(美国英语),如travel / travel(l)ing。现在进行时的结构句式 结构肯定句 主语+ am / is / are +动词-ing形式+其他.否定句 主语+ am / is / are + not +动词-ing形式+其他.一般疑问句 Am / Is / Are +主语+动词-ing形式+其他?肯定回答 Yes, 主语+ am / is / are.否定回答 No, 主语+ am / is / are + not.特殊疑问句 疑问词+ am / is / are +主语+动词-ing形式+其他?考试中常考的现在进行时的应用 (1)

6、当句子中有now时,常表示动作正在进行,这时要用现在进行时。如: They are playing basketball now.现在他们正在打球。(2)以look, listen开头的句子,提示我们动作正进行,这时要用现在进行时。如: Listen!She is singing an English song.听,她正在唱英语歌。 (3)表示当前一段时间或现阶段正在进行的动作,且此时有this week, these days等时间状语,这时常用现在进行时。如: We are making model planes these days.这些天我们在做飞机模型。 (4)描述图片中的人物的动作
