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：
 

一 、单选

1、 Look! He _____their mother do the housework.

2 、_____are the boys doing ? They are singing in the room.

4 、Danny ______. Don’t call him.

5 、–When_____he_____back?

    – Sorry, I don’t know.

A. does,come       B.are coming    C.is come    D.is coming

答案：A  C  A  B  D

二 、填空

1、 It’s ten o’clock. My mother _____(lie)in bed.

2、 What____he _____(mend)?

3、 We _____(play)games now.

4、 What ____you____(do) these days?

5、 ____he ___(clean) the classroom?

6、 Who____(sing)in the next room?

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

      5 Is cleaning  6 is singing  7 likes ;  is wearing
 

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。
