一、概念

現(xiàn)在進行時表示說話時正在進行或發(fā)生的動作,也可表示當前一段

時間內(nèi)的活動或現(xiàn)階段正在進行的動作．

結(jié)構(gòu)：助動詞be(am/is/are)+現(xiàn)在分詞.

二、現(xiàn)在分詞的構(gòu)成：

1.大多數(shù)動詞后可在動詞后直接加-ing．

Eg:carry-carrying,catch-catching,drink-drinking,enjoy-

enjoyinghurry-hurrying,do-doing,read-reading,think-thinking

2.如果動詞以-e結(jié)尾,則去掉-e,再加-ing,

如come-coming,have-having,make-making,ride-

riding,write-writing,take-taking,u-using．

3.如果動詞只有一個元音字母,而其后跟有一個輔音字母時,將此輔

音字母雙寫,再加-ing

如：hit-hitting,let-letting,put-putting,run-running,sit-sitting．

4.如果動詞有兩個音節(jié),且重音在第二個音節(jié)上,則末尾的輔音字母

須雙寫,再加-ing,

如:for’get-forgetting,pre’fer-preferring,up’t-

uptting．試比

較’benefit/benfiting,’differ/differing,’profit/profiting,這些詞

的.重音在第一個音節(jié)上,因此其末尾的輔音字母不雙寫．

5.以-ic結(jié)尾的動詞,應先把-ic變?yōu)?ick,再加-ing,eg:

panic/panicking,picnic/picnicking,但lie/lying,die/dying,tie/tying

是特殊變化要記?。?/p>

三、句型結(jié)構(gòu)：

1.現(xiàn)在進行時的肯定形式、否定形式、疑問形式及其回答,所有變

化都體現(xiàn)在助動詞be(is/am/are)上．

1)現(xiàn)在進行時的肯定形式：主語+be(am/is/are)+doing+其他成

分

ewriting.

2)現(xiàn)在進行時的否定形式:主語+be(am/is/are)+not+doing+其

他成分

en’twriting.

3）一般疑問句及回答：be(am/is/are)+主語+doing+其他成分

AmIsinging?Yes,youare./No,youaren’t.

Aretheywriting?Yes,theyare./No,theyaren’t.

4)特殊疑問句及回答:特殊疑問詞+be(am/is/are)+主語+doing+

其他成分

Whatareyoudoing?Weareplaying(要求就提問內(nèi)容具體回

答).

2.縮寫形式如下:

Iam---I’mYouare---You’reHeis---He’sSheis---She’s

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

3.說明:不是所有動詞都能用現(xiàn)在進行時態(tài)的,如：

e、like、want、know等動詞往往都不用進行時態(tài)．

四．用法：

1.表示現(xiàn)在(指說話人說話時)正在發(fā)生的事情．往往與now,at

themoment,just等副詞連用,以示強調(diào)．

eyoudoing?Someone’s

knockingatthedoor．

2.正在進行著的動作可視為未完成的動作：

He’stalkingtohisfriendsintheclassroom.

可用still一詞強調(diào)動作的持續(xù)性

He’sstilltalkingtohisfriendsintheclassroom.

3.表示長期的或重復性的動作,說話時動作未必正在進行．

swritinganotherarticle.

Don’ther’susingit.

.

4.現(xiàn)在進行時可用來表示不會長期發(fā)生的動作或情況,或被認為在

短期內(nèi)正在進行的動作或存在的情況：

What’syourbrotherdoingthedays?He’sstudying

EnglishatOxfordUniversity.

5.現(xiàn)在進行時也可以用來表示當前的動向：

Peoplearebecomingmoreandmorebeautifulthedays.

6.表示漸變的動詞有：become,turn,get,grow,run,go,begin等．

Theleavesareturningbrown.

It’sgettingcolderandcolder.

7.與always,constantly,forever等詞連用,表示反復發(fā)生的動作或

持續(xù)存在的狀態(tài),往往帶有說話人的主觀色彩．

Youarealwayschangingyourmind.

8.現(xiàn)在進行時(以及begoingto）可以表示為將來安排好的活動

和事件We’respendingnextwinterinChina.用

arrive,come,go,leave等動詞的現(xiàn)在進行時描寫行程安排,也通常有

“將到達”和“將離去”的意思：He’sarrivingtomorrow

morning.

贊揚等的意思：

night.
