现在进行时

一、概念

现在进行时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.

结构:助动词be ( am / is / are ) +现在分词.

二、现在分词的构成:

1. 大多数动词后可在动词后直接加-ing.

Eg: carry-carrying,catch-catching,drink-drinking, enjoy-enjoying hurry-hurrying ,do-doing , read-reading , think-thinking

2. 如果动词以-e 结尾,则去掉-e,再加-ing,

如come-coming , have-having , make-making,ride-riding,write-writing,take-taking,use-using.

3. 如果动词只有一个元音字母,而其后跟有一个辅音字母时,将此辅音字母双写,再加-ing

如:hit-hitting,let-letting, put-putting,run-running,sit-sitting .

三、句型结构:

1. 现在进行时的肯定形式、否定形式、疑问形式及其回答,所有变化都体现在助动词be ( is / am / are )

上.1)现在进行时的肯定形式:主语+be(am/ is/are)+doing+其他成分

I am singing . They are writing .

2)现在进行时的否定形式:主语+be(am/ is/are)+not +doing+其他成分

I am not singing . They aren ’t writing .

3)一般疑问句及回答:be(am/ is/are)+ 主语+doing+其他成分

Am I singing ? Yes ,you are . / No ,you aren ’t .

Are they writing ? Yes ,they are . / No ,they aren ’t .

4)特殊疑问句及回答: 特殊疑问词+be(am/ is/are)+主语+doing+其他成分

What are you doing ? We are playing 要(

求就提问内容具体回答).

2. 缩写形式如下:

I am---I ’m You a-r-e-You’re He is---H e’s She-i-s- She’s

It is--- It ’s We a--r-e We’re They are---They’re

3. 说明: 不是所有动词都能用现在进行时态的,如:

see、like 、want、know 等动词往往都不用进行时态.

四.用法:

1.表示现在( 指说话人说话时) 正在发生的事情.往往与now,at the moment,just 等副词连用,以示强调.

We are waiting for you. What are you doing? Some one

2.正在进行着的动作可视为未完成的动作:

He’s talking to his friends in the classroom.

可用still 一词强调动作的持续性

He’s still talking to his friends in the classroom.

knockin’g s at the door.

3. 表示长期的或重复性的动作,说话时动作未必正在进

行.Mr. Black is writing another article.

Don’t take that book away. Your father ’s using it.

She is learning piano under Mr. Black.

4. 现在进行时可用来表示不会长期发生的动作或情况,或被认为在短期内正在进行的动作或存在的情况:
