现在进行时讲解
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．
如: 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．
4. 如果动词有两个音节,且重音在第二个音节上,则末尾的辅音字母须双写,再加-ing,
如: for’get-forgetting,pre’fer-preferring,up’set-upsetting．试比较 ’benefit/benfiting, ’differ/differing,’profit/profiting,这些词的重音在第一个音节上,因此其末尾的辅音字母不双写．
5. 以 -ic 结尾的动词,应先把 -ic 变为 -ick,再加 -ing,eg: panic/panicking,picnic/picnicking,但 lie/lying ,die/dying,tie/tying是特殊变化要记住．
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---He’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．
