初中英语现在进行时课件

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-

enjoyinghurry-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,u-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’t-

uptting．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

ewriting.

他成分

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

2.缩写形式如下:

Itis---It’sWeare---We’reTheyare---They’re

3.说明:不是所有动词都能用现在进行时态的,如：

e、like、want、know等动词往往都不用进行时态．

themoment,just等副词连用,以示强调．
