  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+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.

  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上.

  1)现在进行时的肯定形式:

主语+be+doing+其他成分

  Iamsinging.Theyarewriting.

  2)现在进行时的否定形式:

主语+be+not+doing+其他成分

  Iamnotsinging.Theyaren’twriting.

  3)一般疑问句及回答:

be+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+主语+doing+其他成分

  Whatareyoudoing?

  Weareplaying.

  2.缩写形式如下:

  Iam---I’mYouare---You’reHeis---He’sSheis---She’sItis---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.表示现在正在发生的事情.往往与now,atthemoment,just

  等副词连用,以示强调.Wearewaitingfor

  you.Whatareyoudoing?

  Someone’s

  knockingatthedoor.

  2.正在进行着的动作可视为未完成的动作:

  He’stalkingtohisfriendsinthe

  classroom.可用still一词强调动作的持续性He’sstilltalkingtohisfriendsinthe

  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.Blackiswritinganother

  article.Don’ttakethatbook

  away.Yourfather’susing

  it.Sheislearningpianounder

  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’syourbrotherdoingthesedays?

  He’sstudyingEnglish

  atOxford

  University.

  5.现在进行时也可以用来表示当前的动向:

Peoplearebecomingmoreandmorebeautifulthese

  days.

  6.表示渐变的动词有:

become,turn,get,grow,run,go,begin等.Theleavesareturning

  brown.It’sgettingcolderand
