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,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
ewriting.
2)现在进行时的否定形式:主语+be(am/is/are)+not+doing+其
他成分
en’twriting.
3）一般疑问句及回答：be(am/is/are)+主语+doing+其他成分
AmIsinging?Yes,youare./No,youaren’t.
Aretheywriting?Yes,theyare./No,theyaren’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
Whatareyoudoing?Weareplaying(要求就提问内容具体回
答).
2.缩写形式如下:
Iam---I’mYouare---You’reHeis---He’sSheis---She’s
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：
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
themoment,just等副词连用,以示强调．
eyoudoing?Someone’s
knockingatthedoor．
2.正在进行着的动作可视为未完成的动作：
He’stalkingtohisfriendsintheclassroom.
可用still一词强调动作的持续性
He’sstilltalkingtohisfriendsintheclassroom.
3.表示长期的或重复性的动作,说话时动作未必正在进行．
swritinganotherarticle.
Don’ther’susingit.
.
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’syourbrotherdoingthesedays?He’sstudying
EnglishatOxfordUniversity.
5.现在进行时也可以用来表示当前的动向：
Peoplearebecomingmoreandmorebeautifulthesedays.
6.表示渐变的动词有：become,turn,get,grow,run,go,begin等．
Theleavesareturningbrown.
It’sgettingcolderandcolder.
7.与always,constantly,forever等词连用,表示反复发生的`动作或
持续存在的状态,往往带有说话人的主观色彩．
