现在进行时
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.
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
Iamsinging.Theyarewriting.
2)现在进行时的否定形式:
主语+be(am/is/are)+not+doing+其他成分
Iamnotsinging.Theyaren’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,atthemoment,just等副词连用,以示强调.
Wearewaitingforyou.Whatareyoudoing?
Someone’sknockingatthedoor.
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.
Mr.Blackiswritinganotherarticle.
Don’ttakethatbookaway.Yourfather’susingit.
SheislearningpianounderMr.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’sstudyingEnglishatOxfordUniversity.
