作谓语的动词用来表示动作（情况）发生时间的各种形式称为时态.
现在进行时表示1、现在（说话的瞬间）正在进行或发生的动作,强调“此时此刻”.E.g.He is reading .They are talking now.
2、当前一段时间内的活动或现阶段正在进行的动作.E.g.They are working these days.
3、 某些动词的现在进行时,表预定的计划或即将发生的动作.E.g I am coming.
其结构为be+现在分词.现在分词的变法有
1、一般在动词词尾加上-ing ,e..g.jump
2、以不发音字母e结尾的动词,先去e,再加-ing.E.g have write
3、.以重读闭音节末尾只有一个辅音字母结尾的词,它前面是单个元音字母时要先将词尾的辅音字母双写,再加上-ing.E.g.sit put
其句式变换都在be上做文章.
E.g.He is buying a bike.
Is he buying a bike?
He isn’t buying a bike.
一般由look,listen,now,at this moment等时间状语做标志.
尽管现在进行时比较简单,但在做题过程中也常会犯一些错误,常见的错误有如下几种：
专项训练：

2、 What____he _____(mend)?
3、 We _____(play)games now.
4、 What ____you____(do) these days?

7 、The girl____(like)wearing a sweater.Look!She ____(wear)a red sweater today.
答案：1 is lying 2 is mending 3 are playing 4 are doing

一 把动词变成现在分词形式易出错
例：1、They are swiming.(swim)
2 、Jenny is plaiing(play)football.
答案：1.swimming 2 .playing
解析：动词变现在分词可有如下口诀:“一添一去y不变”.“一添”指双写规则；“一去”指去掉不发音字母e规则；“y不变”指要与名词变复数区分开.
二 丢掉be动词或忘记把动词变成现在分词
例：1、 Look,two children flying.(fly) a kite in the park.
2 、Li Mingisn’t read ( not read) a book in bed now.
答案：1 are flying 2 isn’t reading
解析:现在进行时肯定句的结构规律为:“be+现在分词,缺一不可”.这一点必须牢记.
三 对动词或动词词组提问时丢掉doing
例：1 、The students are singing in the room.(对划线部分提问)
What are the students in the room?
答案：What are the students doing in the room?
解析:现在进行时态中对动作提问可记住此句式“What +be +主语+doing+其它?”
或简写为“What……doing……”?句式.
四现在进行时态的选择疑问句中易忽视or后用现在分词形式
例：孩子们在跑还是在跳?
Are the children running or jump?
答案：Are the children running or jumping?
解析:or连接的是两个并列成分,动词形式须一致.
