文档介绍：现在进行时态
The present continuous tense
现在进行时
基本用法
eg:---What are you doing?
---I am reading a book.
,但此刻动作不一定正在进行
eg:He is teaching at the school.
We are learning Unit5 these days.
The present continuous tense
现在进行时
如何判断
，如now,at the moment等。
eg:---What are you doing now?
---I am reading a book.
，如listen,look等。
eg:Listen,Lucy is singing!
Look,she is talking with the teacher.
。
eg:Be quiet! The baby is sleeping.
结构: be+doing ( be要根据主语作人称和数的变化)
句型转换
,要在 be 后加 not 构成
eg:We are reading English now.
We are not reading English now.
,把be动词提到句首
eg:The student is drinking. Is the student drinking?
,由“疑问词+一般疑问句”构成
eg:He is working. What is he doing?
现在分词的构成
–ing eg:look looking
,则去e加 -ing
,且末尾只有一个辅音字母的,应双写此字母,再加 –ing. eg:sit sitting
口诀教你学doing
进行时很好记,be加动词-ing;
直加双写去哑e,分词构成须仔细;
别说 be 词无词义,主语和它最亲密;
变疑问 be 提前,否定 not 再 后添;
何时要用进行时 look,listen,now标志.
闭音节：闭音节是以一个元音字母加一个或几个辅音字母结尾的音节。例如：not，thank，ten，am，six等。 重读闭音节就是所谓的元音字母不是发它本身的字母音 .
现在分词的构成规则是:
-ing，例如：go-going, work-working, study-studying, look- looking等。 ，需去掉e再加-ing，例如：make-making, write-writing, skate-skating等。 ，末尾只有一个辅音字母的动词，要双写这一辅音字母，再加-ing。例如： run-running, swim-swimming,begin-beginning等。 begin 和 star符合现在分词构成规则的第三点. listen /lisn/重读在第一个音节上,不符合第三点,所以他属于规则变化,直接加ing就好了. 至于open是双写n加ing的,
Very good!
