1、現(xiàn)在進(jìn)行時(shí)〔語(yǔ)法〕
概念:1、表示說(shuō)話時(shí)正在進(jìn)行的動(dòng)作及行為
2、表示現(xiàn)階段正在進(jìn)行的動(dòng)作。
它的構(gòu)成關(guān)鍵在于 be+v-ing" 。be應(yīng)為助動(dòng)詞,孩子們最容易漏掉,它應(yīng)與主語(yǔ)的人稱和數(shù)
保持一致。 主語(yǔ)不一定是人,也可是物或動(dòng)物。
〔1〕I am^ v-ing +....
〔2〕We7You/They/復(fù)數(shù)名詞+ are + v-ing +....
〔3〕He/She/ It /單數(shù)名詞+ is + v-ing +....如:
I'm doing my homework now .我正在做家庭作業(yè)。〔指說(shuō)話時(shí)正在發(fā)生的動(dòng)作〕 We are worki ng on a far
2、m these days .這些天我們?cè)谝患肄r(nóng)場(chǎng)勞動(dòng)?!仓脯F(xiàn)
階段正在發(fā)生的動(dòng)作〕
Look! He is reading .瞧,他正在看書。
現(xiàn)在進(jìn)行時(shí)是由助動(dòng)詞be的人稱代詞形式加現(xiàn)在分詞構(gòu)成, 動(dòng)詞變現(xiàn)在分
詞的方法:
一般情情況
加-ing
play--play ing, sin g--s inging
以不讀音的字母e結(jié)尾
去e力卩-ing
have— hav ing make — making skate — skati ng dance — dancing
以重讀閉音節(jié)結(jié)尾,末尾只有一個(gè)輔音字母
將末尾輔音字母雙寫,再加-ing
■ ■ ■ ■ ■ I
3、■ I I ■ ■ ■ ■
run — running swim — swimmi ng sit — sitti ng jog--joggi ng,
put — putt ing
二、結(jié)構(gòu)?,F(xiàn)在進(jìn)行時(shí)常有三種句型:
〔1〕肯定式:王語(yǔ)+ be+ v-ing +其它。如:
He is mending his bike .他正在修自行車。
〔2〕否認(rèn)式:主語(yǔ)+ be+ not + v-ing +其它。如:
He is not 〔isn't 〕 mending his bike .他沒(méi)在修自行車。
〔 3〕疑問(wèn)式:主要分一般疑問(wèn)句和特殊疑問(wèn)句兩種句式 。
一般疑問(wèn)句把be動(dòng)詞提前:
4、Be+主語(yǔ)+ v-ing +其它?
如:
—Is he mending his bike ?他正在修自行車嗎?
—Yes,he is .〔No,he isn't .〕是的,他在修。 〔不,他沒(méi)在修。〕 特殊疑問(wèn)句:疑問(wèn)詞+ be+主語(yǔ)+ v-i ng +其它?如:
What is he doing ?他正在干什么?
三、何時(shí)用現(xiàn)在進(jìn)行時(shí)?
分以下幾種情況:
〔1〕以Look!或Listen !開頭的句子,提示我們說(shuō)話時(shí)動(dòng)作正在進(jìn)行,應(yīng)用現(xiàn)
在進(jìn)行時(shí)。如:
Look ! The children are playing games over there .瞧!孩子們?cè)?
那邊做
5、游戲。
Listen ! Who's singing in the classroom ?聽(tīng)!誰(shuí)在教室里唱歌?
〔2〕當(dāng)句子中有now〔現(xiàn)在〕時(shí),常表示說(shuō)話時(shí)動(dòng)作正在進(jìn)行,這時(shí)也常用現(xiàn) 在進(jìn)行時(shí)。如:
We are reading English now .現(xiàn)在我們正在讀英語(yǔ)。
〔 3〕描述圖片中的人物的動(dòng)作時(shí)常用現(xiàn)在進(jìn)行時(shí),以示生動(dòng)。 如:
Look at the picture .The girl is swimming .看這幅圖,這個(gè)女孩 正在游泳。
〔4〕表示當(dāng)前一段時(shí)間內(nèi)的活動(dòng)或現(xiàn)階段正在進(jìn)行的動(dòng)作時(shí)常用現(xiàn)在進(jìn)行時(shí)。 這時(shí)常與時(shí)間狀語(yǔ) these days , this
6、 week 等連用。 如:
We are playing football these days .這些天我們?cè)谔咦闱颉?
〔5〕有時(shí)句子中可能沒(méi)有時(shí)間狀語(yǔ),但如果表示的是說(shuō)話時(shí)或者現(xiàn)階段正在進(jìn) 行的動(dòng)作,就應(yīng)該用現(xiàn)在進(jìn)行時(shí)。 如:
—What's Jim doing ?吉姆在干什么?
—He is cleaning the room .他正在清掃房間。
注意:是不是所有的動(dòng)作都可以用現(xiàn)在進(jìn)行時(shí)?
不是。有一些表示狀態(tài)、結(jié)果、感覺(jué)和感情的動(dòng)詞,如 have〔有〕,be〔是〕, like 〔喜歡〕,know〔知道〕,want〔想要〕,think 〔認(rèn)為〕,see〔看見(jiàn)〕, hear〔
7、聽(tīng)見(jiàn)〕,forget 〔忘記〕等,一般不用現(xiàn)在進(jìn)行時(shí)。如:I have a newbike now.現(xiàn)在我有一輛新的自行車。但不說(shuō): rm hav ing a new bike now .
四、 有些動(dòng)詞的現(xiàn)在進(jìn)行時(shí)表示近期按方案或安排要進(jìn)行的動(dòng)作。這些動(dòng)詞是
go,come,leave,start,arrive,return,work,sleep,stay,play,d o,have,wear, die 等。如:
She's coming to see me tomorrow. 她明天要來(lái)看我。
The football match is starting next Monday.
8、足球賽在下星期一開始。
五、 另外,有一些表示狀態(tài)和感覺(jué)的動(dòng)詞,一般不用于現(xiàn)在進(jìn)行時(shí)態(tài) (如果詞義
轉(zhuǎn)變那么可以 ) 。它們是
be,love,like,hate,want,hope,need,prefer,wish,know,understand,remember ,guess,mean,think( 以為), feel, seem, look( 看起來(lái) ),see, own, hear, find, mind( 在意),have(有)等。
