主讲人:李萍(一)现在进行时的概念及构成:现在进行时是表示现在正在进行的动作的时态。时间状语:now,thesedays,atthemoment提示词:look,listen•基本构成:主语+be+v-ing(现在分词)•IamwatchingTVnow.我正在看电视。进行时的肯定句Wearecyclinginthegardenthesedays.Look!Heiswalkingthedog.顺口溜:动词后加ing,前面不要忘了be.(1)否定式:be+not+V-ingeg:Thestudentsaren’tcleaningtheroom.(2)一般问句:be动词提前。肯定:Yes,主语+be,否定:No,主语+benot。eg:---Areyouplayingthecomputergame?---Yes,Iam./No,Iamnot.(二)否定式、疑问式及简略回答(3)特殊问句:对谓语动词进行提问的:What+be+主语+doing+其他?Whatistheoldmandoingunderthetree?对其他成份进行提问的,疑问词+一般疑问句?Whereistheboyswimming?Whoisshewaitingfor?(三)现在分词大变身大家刚刚了解到,现在进行时的结构是“be+现在分词”,那么你知道动词现在分词是怎么变身的吗?我们还是用一个脍炙人口的口诀来记住吧:现在分词用途多,进行时态不可缺。它的构成很好记,动词后缀ing。词尾若有哑音e,去e再加没问题。一辅重读闭音节,这个字母要双写。还有一点要注意,改ie为y再加ing。(四)现在进行时的基本用法(1)以Look!或Listen!开头的句子,提示我们说话时动作正在进行,应用现在进行时。如:Look!Thechildrenareplayinggamesoverthere.瞧!孩子们在那边做游戏。Listen!Who‘ssingingintheclassroom?听!谁在教室里唱歌?(2)当句子中有now(现在)时,常表示说话时动作正在进行,这时也常用现在进行时。如:WearereadingEnglishnow.现在我们正在读英语。(3)描述图片中的人物的动作时常用现在进行时,以示生动。如:Lookatthepicture.Thegirlisswimming.看这幅图,这个女孩正在游泳。(4)表示当前一段时间内的活动或现阶段正在进行的动作时常用现在进行时。这时常与时间状语thesedays,thisweek等连用。如:Weareplayingfootballthesedays.这些天我们在踢足球。(5)有时句子中可能没有时间状语,但如果表示的是说话时或者现阶段正在进行的动作,就应该用现在进行时。如:—What'sJimdoing?吉姆在干什么?—Heiscleaningtheroom.他正在打扫房间。have(有),be(是),like(喜欢),know(知道),want(想要),think(认为),see(看见),hear(听见),forget(忘记)等。eg:Ihaveanewbikenow.现在我有一辆新的自行车。但不说:I'mhavinganewbikenow.没有进行时的动词:(6)有些动词的现在进行时表示近期按计划或安排要进行的动作。这些动词是:go,come,leave,start,arrive,return,work,sleep,stay,play,do,have,wear,die等。如:She'scomingtoseemetomorrow.她明天要来看我。ThefootballmatchisstartingnextMonday.足球赛在下星期一开始。三、随堂练习A组:客观题选择填空。(共5分,每小题1分)(备注:基础题)1.It's12o'clock.MrGreen________lunch.A.haveB.hasC.arehavingD.ishaving2.Tom_________anEnglishclassnow.A.ishavingB.hasC.havingD.have3.Look!He_____theirmotherdothehousework.A.helpsB.arehelpC.ishelpD.ishelping4.Don’ttalkhere.Mymother_____.A.issleepingB.aresleepingC.sleepingD.sleep5.Danny______.Don’tcallhim.A.iswriteingB.iswritingC.writingD.writesB组:主观题I.用括号中所给动词的适当形式填空。(共10分,每小题1分)(备注:基础题)1.It’steno’clock.Mymother_____(lie)inbed.2.We_____(play)gamesnow.3.What____you____(do)thesedays?4.____he___(clean)theclassroomatthemoment?5.Listen!Who____(sing)inthenextroom?6.—Whataretheydoingnow?---They___________(put)onnewclothes.6.Thegirl____(like)wearingasweater.Look!She____(wear)aredsweatertoday.7.Look!Tomandhisparents___________(swim)intheriver.8.—Whataretheydoingnow?---They___________(put)onnewclothes.9.It'sfiveo'clock.Thestudents________(play)footballontheplayground.10.Listen!Jim'sradio________(make)aloudnoise.Wouldyoupleasetellhim________(turn)itdown?II.根据中英文提示,完成句子。(共10分,每小题2分)(备注:中档题)1.–吉姆在哪儿?--他正在房间里写作业。--WhereisJim?–He______________________hishomeworkinhisroom.2.我爸爸现在正在楼上看报纸。Myfather____________________anewspaperupstairs.3.孩子们正在公园里玩得很开心。Thechildren______________________inthepark.4.人们正在为春节作准备。Peopleare____________________________theSpringFestival.5.玲玲正在帮妈妈打扫房子。Lingling_______________________________theroomnow.答案:A组:1.D2.A3.D4.A5.BB组:一、1.islying2.areplaying3.are;doing4.Is;cleaning5.issinging6.likes;iswearing7.areswimming8.areputting9.areplaying10.ismaking;toturn二、1.isdoing2.isreading3.arehavingagoodtime4.gettingreadyfor5.ishelpinghermotherclean
