2010年中考英语时态复习系列(一)现在进行时

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:

1 Look! He _____their mother do the housework.

A. is helping     B. are help     C. is help    D.is helpping

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

    – Sorry, I don’t know.

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

答案A  C  A  B  D

、填空

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

  把动词变成现在分词形式易出错

例:1They 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。

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 Mingisnt read ( not read) a book in bed now.

答案:1 are flying  2 isnt 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。

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。

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。
