Keygrammar
現(xiàn)在進(jìn)行時(shí)態(tài)
一、現(xiàn)在進(jìn)行時(shí)的用法
1、表示說話時(shí)正在進(jìn)行或發(fā)生的動(dòng)作。如：
I’mbabysittingmyyoungerbrother.我在照看我弟弟。
It’srainingoutside.外面正在下雨。
2、表示現(xiàn)階段一直在進(jìn)行或不斷重復(fù)的動(dòng)作，但說話時(shí)該動(dòng)作并不一定在進(jìn)行。如：
He’swatchinganinterestingTVplaythesedays.
近來，他在看一部很有趣的電視劇。
AreyouteachingEnglishinaschool?你在學(xué)校教英語嗎？
3、表示最近的確定安排，即根據(jù)計(jì)劃或安排在近期內(nèi)將要發(fā)生的動(dòng)作。這是表示眼前打算最普通的說法，但一般要與表示將來的時(shí)間連用，以避免現(xiàn)在進(jìn)行時(shí)和一般將來時(shí)的含義上的混淆。例如：
I’mmeetingyouattheairportthisevening.今晚，我會(huì)到機(jī)場(chǎng)接你。
Whatareyouhavingfordinner?晚飯吃什么？
4、表示從一個(gè)地方到另一個(gè)地方位置移動(dòng)的動(dòng)詞（如go,come,drive,fly,travel,arrive,leave,start,visit，run，return等），以及動(dòng)詞do等的現(xiàn)在進(jìn)行時(shí)形式，可以用來表示沒有確定安排的決定或計(jì)劃。
He’sleavingforBeijingtomorrow.他明天動(dòng)身去北京。
WhatareyoudoingnextSunday?下星期天你要干什么？
5、現(xiàn)在進(jìn)行時(shí)和always，usually，allthetime等連用時(shí)，表示一種經(jīng)常、反復(fù)的動(dòng)作，且說話人往往帶有某種感情色彩（如贊揚(yáng)、欣賞、厭煩、批評(píng)、驚訝、不理解等）。例如：
She’salwayshelpingothers.她總是樂于助人。（表示贊賞）
Youarealwaystalkinginclass.你上課老是說話。（表示批評(píng)）
二、現(xiàn)在進(jìn)行時(shí)的謂語部分構(gòu)成
現(xiàn)在進(jìn)行時(shí)在句式的變化上，都應(yīng)在助動(dòng)詞be上做文章。
1、肯定式：be（am,is,are）+Ving(現(xiàn)在分詞)如：
TheyarehavinganEnglishclass.他們?cè)谏嫌⒄Z課。
2、否定式：be(am,is,are)+not+Ving(現(xiàn)在分詞)如：
Theyaren’thavinganEnglishclass.他們不在上英語課。
3、疑問式：將be的具體形式（即am,is或are）提前到句首。如：
AretheyhavinganEnglishclass？他們?cè)谏嫌⒄Z課嗎？
助動(dòng)詞變化口訣：變疑問，往前提，句后問號(hào)莫丟棄；變否定，更容易，be后not莫忘記。
三、現(xiàn)在分詞的變化規(guī)則
1、一般在詞尾加-ing（一般-ing）。例如：going，playing，knowing
2、以不發(fā)音的字母e結(jié)尾，先去e再加-ing（去啞e）。例如：making，arriving，coming
3、以重讀閉音節(jié)結(jié)尾，且詞尾只有一個(gè)輔音字母時(shí)，先雙寫這個(gè)輔音字母，再加-ing（重閉單輔先雙寫）。例如：running，stopping，preferring
4、以-ie結(jié)尾，先將-ie改成y，再加-ing。例如：tying，dying,lying
口訣：現(xiàn)在進(jìn)行ing,以e結(jié)尾要去e，除去幾個(gè)特殊詞，系住tie-tying死去die-dying要躺下lie-lying，直接ie變成y。
四、現(xiàn)在進(jìn)行時(shí)態(tài)的常見提示語
1、在漢語中，通常有“在，正在”等提示詞。如：
我在做作業(yè)。Iamdoingmyhomework.
2、在英語中，最常見的提示詞有now，look，listen以及atthemoment（此時(shí)此刻）等。如：
Look，theyareplayingfootball.瞧！他們?cè)谔咦闱颉?br> 五、運(yùn)用現(xiàn)在進(jìn)行時(shí)常見的幾個(gè)錯(cuò)誤
1、把動(dòng)詞變成現(xiàn)在分詞形式易出錯(cuò)。例：
（1）誤：Theyareswiming(swim).
正：Theyareswimming(swim).
（2）誤：Jennyisplaiing(play)football.
正：Jennyisplaying(play)football.
解析：A、動(dòng)詞變現(xiàn)在分詞可有如下口訣:一般-ing；啞e先去e；重閉單輔先雙寫；-ie結(jié)尾y來替。
B、動(dòng)詞現(xiàn)在分詞的變化規(guī)則要與名詞變復(fù)數(shù)、動(dòng)詞變現(xiàn)單三等規(guī)則區(qū)分開來。
2、謂語部分的構(gòu)成不完整：丟掉be動(dòng)詞，或忘記把動(dòng)詞變成現(xiàn)在分詞。例：
（1）誤：Look!Twochildrenflying(fly)akiteinthepark.
正：Look！Twochildrenareflying(fly)akiteinthepark.
（2）誤：LiMingisn’tread(notread)abookinbednow.
正：LiMingisn’treading(notread)abookinbednow.
解析：現(xiàn)在進(jìn)行時(shí)的謂語部分的構(gòu)成是“be+現(xiàn)在分詞”，二者缺一不可，這一點(diǎn)必須要牢記。
3、對(duì)動(dòng)詞或動(dòng)詞詞組提問時(shí)，丟掉代動(dòng)詞doing。例：
Thestudentsaresingingintheroom.(對(duì)劃線部分提問)
→誤：Whatarethestudentsintheroom?
→正：Whatarethestudentsdoingintheroom?
解析：現(xiàn)在進(jìn)行時(shí)態(tài)中對(duì)動(dòng)作提問可記住此句式“What+be+主語+doing+其它?”或簡(jiǎn)寫為“What......doing......?”句式。
4、現(xiàn)在進(jìn)行時(shí)態(tài)的謂語部分是并列結(jié)構(gòu)時(shí)，容易忽視第二個(gè)以及第二個(gè)以后的動(dòng)詞用現(xiàn)在分詞形式。例：
孩子們?cè)谂苓€是在跳？
誤：Arethechildrenrunningorjump?
正：Arethechildrenrunningorjumping?
解析:or連接的是兩個(gè)并列成分，動(dòng)詞形式須一致。

如：Lucycan’tbeathomenow,shewenttotheparkjustnow.
Wherecanitbe?Ican’tfindmyfootball.

1）could是can的過去式,有兩種用法,一種表示過去式；一種用來表達(dá)更加客氣,委婉的語氣,時(shí)態(tài)性不強(qiáng),可用于過去，現(xiàn)在。
2）beableto意為“有能力，能夠做...”,相當(dāng)于can/could,但它有人稱，數(shù)和時(shí)態(tài)的變化。
2.may;maynot(否定)
1)表示“請(qǐng)求，許可”，此時(shí)與can同義，可以互換使用
如：MayIborrowyourbike?CanIborrowyourbike?
Yes,youmay./No,youmaynot.Yes,youcan./No,youcan’t.
2)may/might表示不太肯定的猜測(cè)，意為“有可能”
如：Lucymaycometoschoollatetoday.
Itmightraintoday.
：might是may的過去式,有兩種用法,一種表示過去式，一種表示更加委婉,客氣的語氣或?qū)赡苄缘膽岩伞?br> 3.must;mustn’t(否定)
1)must(“必須”,表示命令)，mustn’t(“一定不能”,表示強(qiáng)烈禁止...)
如：Youmustgotobedbefore22:00pm.
Youmustn’tplaywithfire.It’sdangerous!
--MustIwritedownthesentences？
--No，youneedn’t.(--No,youdon’thaveto)
注意：在回答must的疑問句中，否定回答用needn’t或don’thaveto表示“不必”，不用mustn’t
2)must還可以表示非常肯定的猜測(cè)，意為“一定”
如：ThegirlinaredskirtmustbeLucy.
3)must/haveto的區(qū)別：
①.must表示必須，強(qiáng)調(diào)主觀上的愿望；haveto表示“不得不”，強(qiáng)調(diào)客觀需要
如：Youmustgobebedbefore22:00pm.Mybikeisbroken,soIhavetogotoschoolonfoot.
②.haveto有人稱、數(shù)、時(shí)態(tài)的變化；must則沒有。
如：Ihavetocleantheclassroomtoday.Shehastofinishherhomeworkfirst.
Itwaslate,hehadtogotoschoolwithoutbreakfast.
