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.

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 ’benefitbenfiting, ’differdiffer
ing,’profitpr
ofiting,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.

-
ing,eg: panicpanicking,picnicpicnicking,但
lielying ,diedying,tietying是特殊变化要记住.
