Procedures

StepⅠ Revision

◎Greetings

T:Class begins

S:Good morning,Miss Liu.

T:Good mornig,class.

S:Thank you.

T:Set down,please.

◎Say“what are you doing？”（talk about this topic with students）

Step II Lead in

(Show sonme pictures)

Look at these pictures and answer the question“what are they doing？”Step III Language focus

Pay attention to the sentences，and say how to use The Present Continuous Tense .

用法：

(1)现在进行时态表示现在(说话瞬间)正在进行或发生的动作。

Eg.The students are listening to the teacher.

He is watching TV now.

(2)现在进行时态还可以表示当前一段时间内的活动或现阶段正发生的事情。如:

Eg.We are working on a farm these days .

I am writing a book this month.

Point out the form of the Present Continuous Tense:

be (am/is/are)+doing

肯定式结构:主语+be+doing+其他.

否定式结构:主语+be+not+doing+其他.

一般疑问结构: Be+主语+doing+其他？

特殊疑问结构: 疑问词+（be+主语+doing？)

How to change verbs’v-ing：

1)一般动词后直接加-ing. 如：reading, watching, seeing

2)以不发音的e结尾的词去掉e再加-ing.如: make—making write—writing

3)以重读闭音、单辅音字母结尾的词，双写这个辅音字母，再加-ing.如: get-getting, swim-swimming ，put-putting,run-running

Practice v-ing：

draw drink speak eat think read

talk clean watch run swim write

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 无词义,主语和它最亲密；变疑问be 提前,否定not 在后添；何时要用进行时，look,listen,now标志.
