readingpassage.1.

现在进行时可表示现在(说话瞬间)正在进行的动作或存在的状态，常与时间状语now

连用。当句中出现Look!Listen!等暗示词语时，往往说明后面句中的谓语动词所表示的动作正在发生，应当用现在进行时。e.g.Jimisswimmingnow.

Listen!Thelittlegirlissingingintheclassroom.

Don’ttalk!I’m

doingmyhomework.现在进行时含义Grammar2.

现在进行时还可表示现阶段正在进行的动作，常与thesedays,atpresent(目前)等时间状语连用。e.g.Mygrandpaisworkingonthefarmthesedays.

SamisstudyinginBeijingatpresent.▶现在进行时的陈述句结构：

主语+am/is/are+动词-ing形式(+其他).▶现在进行时的否定句结构：

主语+am/is/are+not+动词-ing形式(+其他).句式结构e.g.I’m

notflyingakitenow.Look!Jimisnot/isn’tlisteningtohisteacher.Wearenot/aren’tplayingfootball.

▶现在进行时的一般疑问句结构：

Am/Is/Are+主语+动词-ing形式(+其他)?肯定回答：Yes,

主语(人称代词)+am/is/are.否定回答：No,

主语(人称代词)+am/is/are+not.e.g.—IsyourdadwatchingTV? —Yes,heis./No,heisn’t. —Areyoucleaningyourbedroomnow? —Yes,Iam./No,I’mnot.▶现在进行时的特殊疑问句结构：疑问词(不作主语)+其一般疑问句式?

对特殊疑问句的回答，要根据实际情况来回答。当疑问词在句中作主语时，现在进行时的特殊疑问句采用陈述句语序：疑问词+is/are+动词-ing

形式(+其他)?e.g.—Whatareyoudoing? —Iamcookingdinner. —Wherearetheyplaying? —They’replayingunderthetree. —Whoisrunninginthepark? —Myfriend.1.

一般情况下，在动词词尾直接加-ing。

e.g.talk

→

talking

work

→

working动词-ing形式的构成规律2.

以不发音的元音字母e结尾的动词，需去掉e再加-ing。

e.g.write

→

writing

make

→

making3.

以“辅音字母+一个元音字母+一个辅音字母”这样的重读闭音节结尾的动词，要双写末尾的辅音字母，再加-ing。

e.g.sit

→

sitting

run

→
