Presentatin

He is lying in the grass.

当我们描述一个正在发生的动作时要用现在进行时(the present cntinuus tense)
I am eating.Yu/ We/ They are eating.He/ She/ It is eating.
一、现在进行时肯定句和否定句的构成： 肯定句: 主语+ am/ is /are + v-ing ... 否定句: 主语+ am/ is / are nt + v-ing ...
I am nt eating.Yu/ We/ They are nt eating.He/ She/ It is nt eating.
二、动词ing形式的构成：
写出下列动词的现在分词形式
read — play — dance — write — sit — get—have — eat — lk — carry— begin — put—
take — swim— leave — shine — make — sleep —cut — change — lie — study — pay — visit — wait —
1. Lk! Simn _________ (play) ftball with his friends in the playgrund.2. It’s 4 ’clck in the afternn. Daniel __________ (study) in the classrm.
Cmplete the sentences with the crrect frms f the verbs in brackets.

is practising
are waiting
I am eating. → Am I eating? Yes, I am. / N, I am nt. (或 N, I’m nt.)
三、现在进行时一般疑问句的构成及回答：
Yu/ We/ They are eating.→ Are yu/ we/ they eating? Yes, we/yu/ they are. N, we/ yu/ they are nt (或用缩写aren’t)
He/ She/ It is eating. → Is he/ she/ it eating?Yes, he/she/it is. N, he/she/it is nt. (或用缩写isn’t)
规律：将be 动词移到主语前面。注意：肯定回答时主语be动词不能缩写，否定回答时be动词和nt可以用完全形式也可以用缩写。
Sandy: Hell, Amy. ___ yu _____ yur hmewrk nw? Amy: N, I’m nt. My cusin Shirley _________ (visit) me.Sandy: Oh, really? What __ she _______ (d) nw?

Guessing Game
一、现在进行时可以表示说话时正在进行或发生的动作，也可表示当前一段时间内的活动或现阶段正在进行的动作。
Lk! He is reading in bed. (说话时正在进行）Mr Green is writing a new bk. (现阶段正在做）
二、现在进行时的判断方法： 如果句子中带有鲜明的时间状语，如：nw 或带有lk, listen 等暗示动作正在发生，或有表示现在的上下文语境时，我们常用现在进行时。
Listen! She is singing in the next rm.—Where is yur mther? — She is cking dinner.
三、注意点： （1）现在进行时的谓语动词由“be 的某种形式+ 动词ing 形式” 这两部分构成。这时be是个助动词，没有实际意思，只起构成时态的作用。同学们在使用现在进行时时千万不要忘了用be动词。
We having breakfast. (错）
We are having breakfast. (正)
(3) 双写末尾一个辅音字母再加ing的规律不易掌握, 所以同学们可以在学习英语的过程中学到一个双写词就记住它, 慢慢体会规律。以下是已经学过的一部分双写词：shp, run, get, swim, begin, stp, cut, hit, frget等。
(2) 有些动词一般不用进行时，如：knw, understand(理解), lve, like, want, hpe, hear, see等。
一. 请写出下列动词的-ing形式。1. talk ______ 2. dance ______ 3. clean ______ 4. begin ________ 5. tie ______ 6. invite _______ 7. shp ________ 8. put ______
