初中英语语法之现在进行时精讲+精练+答案.docx

（一）基本用法：
（1）表示（说话瞬间）正在进行或发生的动作。
I’m visiting my friends now. 
（2）表示现阶段正在进行的动作或存在的状态。
     His is learning English this year.
（二）  谓语构成：be (am/ is/ are)＋v-ing （动词的现在分词）
【注意】be要与主语的人称和数保持一致。如：
  I’m watching TV now. 我现在正在看电视。
  They’re playing football. 他们正在踢足球。
（三）现在分词的构成。
（1）一般情况下在动词词尾+ing。
     go→going      look→looking
（2）以不发音的e结尾的动词，去掉e+ing。
     have →having    write→writing
（3）以一个辅音字母结尾的重读闭音节（辅元辅结构），双写最后一个字母，+ing。
      get→getting   run→running  begin→beginning
(4) 特殊形式 lie-lying  die-dying
（四）现在进行时态的肯定式、否定式、疑问式及简略回答。
（1）肯定式：主语+be＋v-ing +其他   
 He is running. 他正在跑。      
The students are cleaning the classroom now .
（2）否定式：主语+be＋not＋v-ing +其他   
 He is not running.
The students aren’t cleaning the room now. 
（3）一般问句：be动词提前。“Be+主语+v-ing+其他？”
肯定答语Yes，主语＋be.
否定答语No，主语＋be not.
Is he running?      
Yes, he is.  No, he isn’t.
（4）特殊问句式：“疑问词+be ＋主语＋v-ing＋其他？”
a.  对谓语动词进行提问的：What＋be ＋主语＋doing＋其他？
What is the  man doing under the tree? 
b.  对其他成份进行提问的，疑问词＋一般疑问句？
Where is the boy swimming? 
五、 现在进行时与一般现在时的区别
（一）现在进行时表示动作的暂时性，而一般现在时表示动作的习惯性和经常性
I am watching TV now. （暂时性）我现在在看电视。
I watch TV every day. （经常性） 我每天都看电视。
（二）现在进行时可表示短暂性动作，而一般现在时表示长久性动作。
Lucy is living in Beijing.（短时间居住）露西暂时住在北京。
Lucy lives in Beijing. （长久性居住） 露西在北京居住或生活。
（三）有些动词不能用进行时，know, understand, love, like, hate, wish, want, think, hope, have, believe, agree, hear, see, notice。这些动词通常用一般现在时表示说话时发生的动作。
1) 表示“拥有”的动词。如have (has) 等。
例句：I have a nice bike now. (我现在有一辆漂亮的自行车。)
不能说成: I am having a nice bike now.
2) 有些表示感觉的感官动词。如：see, find, look (看起来)，hear (听见)等。
例句：We see him. (我们看见他。)
不能说成：We are seeing him.
但是，有些表示感觉的动词，如：listen to, look at 等可用现在进行时。
如：They are listening to the teacher. (他们在听老师讲课。)
3) 表示“喜欢”“厌恶”的动词。如：like, love, hate (讨厌)等。
例句：We love our country. (我们热爱祖国。)
不可说: We are loving our country.
4) 表示知识或脑力的动词。如：think, know, forget等。
例句：I think you are right. (我认为你是对的。)
不能说成：I am thinking you are right.
5) 表示状态的be动词“是”。
例句：She is at home. (她在家。)
不能说成：She is being at home.  
6) 表示“希望”、“愿望”、“心愿”等的动词。如：want 等词。
例句：I want to see her now. (我现在就想见到她。)
不能说成：I am wanting to see her now.
