小学一般现在进行时讲解及练习(简单基础)

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 are---You’re He is---H e’s She is---She’s

It is---It’s We are---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’s knocking at the door．

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.

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：

What’s your brother doing these days? He’s studying English at Oxford University.
