1、中考英語復(fù)習(xí)課件,動詞時態(tài),英語的動詞在表示不同時間里發(fā)生的行為或存在的狀態(tài)時,要用不同的形式來表示,這種不同的形式叫做動詞的時態(tài)。 英語常用的時態(tài)有八種,分別是:一般現(xiàn)在時、現(xiàn)在進(jìn)行時、現(xiàn)在完成時、一般過去時、一般將來時、過去進(jìn)行時、過去完成時和過去將來時。,一、一般現(xiàn)在時 一般現(xiàn)在時表示經(jīng)常發(fā)生的動作(習(xí)慣性的動作)或存在的狀態(tài),句中常用always, usually, often, sometimes, seldom, never, every day等時間狀語。,例如: 1、He goes to school at seven oclock everyday. 2、The sun
2、rises in the east.,二、一般過去時 一般過去時主要用于表示過去時間,句中常有yesterday, ago, in 1989, once, last week (month, year), at that time, just now 等時間狀語。,例如: 1、he was born in 1989. 2、I used to play football when I was young.,三、一般將來時 英語動詞表示將來時間有多種形式,其共同特點是句中常有表示見來時間的狀語,如:tomorrow, next week, in a week。,例如: 1、We will vis
3、it the science museum next week. 2、We are going to discuss the problem tomorrow.,四、現(xiàn)在進(jìn)行時 進(jìn)行時表示現(xiàn)在時刻正在進(jìn)行的動作或表示現(xiàn)階段正在做的事情,句中常用now, at this moment 等時間狀語連用。,例如: 1、The boy is playing video games. 2、His father is writing a novel these days.,五、現(xiàn)在完成時 現(xiàn)在完成時表示從過去某一時刻開始一直延續(xù)到現(xiàn)在的動作或狀態(tài),或還要延續(xù)下去,句中常用:since, for, yet,
4、 already表示的一段時間狀語連用。,例如: 1、Great changes have taken place in China since 1980. 2、I have finished my task.,六、過去進(jìn)行時 過去進(jìn)行時表示在過去某個時候正在進(jìn)行的動作或過去某個階段正在做的事情。,例如: 1、He was reading an interesting book this time yesterday. 2、When I came in, they were having supper.,七、過去完成時 表示在過去某個時刻前已經(jīng)發(fā)生的動作,或者從過去某個時刻開始一直延續(xù)到過
5、去另一時刻的動作和狀態(tài)。,例如: 1、By the end of last year, we had learned more than 2,000 English words 2、My teacher had taught in that school for ten years before she came here.,八、過去將來時 過去將來時表示從過去的觀點來預(yù)計以后要發(fā)生的動作或存在的狀態(tài),這種時態(tài)常用于賓語從句當(dāng)中,主句中的謂語動詞一般是過去時。,例如: 1、He said that he would study harder than before. 2、He didnt te
6、ll me when he would go.,動詞時態(tài)例題選講:,例1:Look, she (have) a bunch of flowers in her hand. 答案:has 。 提示:盡管句中有l(wèi)ook,但在英語中表示“有”,不能用進(jìn)行時態(tài),本句意思指“她手中有一束花”。,例2:John (make) much progress in his lessons since last term. He (study) harder later on. 答案:has made, will/is going to study。
7、 提示:第一句中,since last term暗示了謂語動詞要用現(xiàn)在完成時態(tài)。說明從上學(xué)期以來取得了很大進(jìn)步,第二句中的later on要注意用一般將來時。,例3:Cherry arrived at school after the class (begin) yesterday. 答案:had begun。 提示:begin雖然也能作及物動詞,但在表示某事開始時,一般以不及物動詞出現(xiàn),不用被動結(jié)構(gòu)。,例4:If it (not rain) tomorrow, we (go) to the park. 答案:doesnt rai
8、n, will go。提示:這是條件狀語從句,主句是將來時,其時間或條件狀語從句應(yīng)用一般現(xiàn)在時。,例5:Great changes (take) place in Shanghai in the past ten years. 答案:have taken place。 提示:In the past ten years會造成過去時間感覺,但其意思是近十年中,與現(xiàn)在有關(guān),要用現(xiàn)在完成時。,例6:It is said that they (hold) an English evening next week. 答案:will hold。 提示:主句It is sa
9、id是現(xiàn)在時時態(tài),從句要用將來時,不能用過去將來時。,動詞時態(tài)注意的要點:,(1)將來時除了shall/will +v以外還有be going to +v,表示不久即將發(fā)生的事,be doing(用于某些動詞,如leave, come, start, reach等);be +to +v,可帶時間狀語,表示“必須”; “打算”,be about +to +v,表示“即將”。例如: Hurry up! The bus is starting. We are leaving for Nanjing tomorrow.,(2)有些表示狀態(tài)、感情、感覺的動詞沒有進(jìn)行時。例如:be, like, want
10、, love, hear, wash, hope。,(3)現(xiàn)在完成時與一般過去時都表示動作發(fā)生于過去,但現(xiàn)在完成時強調(diào)結(jié)果,一般過去時強調(diào)時間。例如: Have you been to the Great Wall? How long did you stay in Beijing last year?,課堂鞏固練習(xí)題:用適當(dāng)?shù)膭釉~形式填空。,1、She kept the radio when she ______(do) homework. 2、She was reading newspapers.
