Ⅱ. 幾種常見時(shí)態(tài)的相互轉(zhuǎn)換
英語(yǔ)中的幾種時(shí)態(tài)在一定情況下可以互相轉(zhuǎn)換,以下是幾種常見的轉(zhuǎn)換形式:
一、 一般過去時(shí)與現(xiàn)在完成時(shí)的轉(zhuǎn)換
在現(xiàn)在完成時(shí)中,延續(xù)性動(dòng)詞能與表示一段時(shí)間的狀語(yǔ)連用,瞬間動(dòng)詞卻不能。
I have bought a car.
I have had the car for 3 weeks
I haven’t bought anything for 3 months
但是,可用別的表達(dá)方式:①瞬間動(dòng)詞用于“一段時(shí)間 + ago”的一般過去時(shí)的句型中;②瞬間動(dòng)詞可改成與之相對(duì)應(yīng)的延續(xù)性動(dòng)詞及短語(yǔ),與一段時(shí)間連用;③瞬間動(dòng)詞用于“It is + 一段時(shí)間 + since + 一般過去時(shí)”的句型中,表示“自從……以來有……時(shí)間”的意思,主句一般用it is來代替It has been;④瞬間動(dòng)詞用于“Some time has passed since + 一般過去時(shí)”的句型中。請(qǐng)看:
A. He joined the League [li:ɡ] 聯(lián)盟two years ago.
B. He has been in the League for two years.
C. It is two years since he joined the League.
D. Two years has passed since he joined the League.
二、 一般現(xiàn)在時(shí)與現(xiàn)在進(jìn)行時(shí)的轉(zhuǎn)換
在一般現(xiàn)在時(shí)中,at加上名詞表示“處于某種形態(tài)”,如at work(在工作), at school(上學(xué)、上課)等。彼短語(yǔ)可與進(jìn)行時(shí)態(tài)轉(zhuǎn)換。請(qǐng)看:
Peter is at work, but Mike is at play.
Peter is working, but Mike is playing.
三、 現(xiàn)在進(jìn)行時(shí)與一般將來時(shí)的轉(zhuǎn)換
在現(xiàn)在進(jìn)行時(shí)態(tài)中g(shù)o, come, leave, start, arrive等動(dòng)詞常與表示將來的時(shí)間狀語(yǔ)連用表示將要發(fā)生的動(dòng)作。如:I am coming, Mum! 意為“人就來,媽媽!”請(qǐng)看:
The train is leaving soon.
The train will leave soon.
四、“be going to+動(dòng)詞原形”與“will(shall)+動(dòng)詞原形”結(jié)構(gòu)的轉(zhuǎn)換
“be going to+動(dòng)詞原形”、表示打算、計(jì)劃要做的事;將來時(shí)“will(shall)+動(dòng)詞原形”結(jié)構(gòu)在書面語(yǔ)中,當(dāng)主語(yǔ)為第一人稱時(shí),常用助動(dòng)詞shall。在口語(yǔ)中,所有人稱都可以用will。請(qǐng)看:
We are going to visit the Great Wall next Sunday.
We shall visit the Great Wall next Sunday.
動(dòng)詞時(shí)態(tài)考點(diǎn)分析
一、根據(jù)時(shí)間狀語(yǔ)確定時(shí)態(tài)的原則
1. Hurry up! The play for ten minutes.
A. has begun B. had begun C. has been on D. began
[析] 1.since后接時(shí)間的起點(diǎn),for后接時(shí)間段,主句動(dòng)詞用現(xiàn)在完成時(shí),應(yīng)注意瞬間動(dòng)詞與延續(xù)性動(dòng)詞的使用。
二、特殊疑答句
2.How staying? for five days.
A.long they will be B.they will be
C.long will they be D.long they be
[析] 特殊疑答句 特殊疑答詞(when,where,who,how ,etc.)+一般疑答句
三、根據(jù)上下白已有時(shí)態(tài)信息點(diǎn)確定時(shí)態(tài)的原則
3. –When this kind of computer ?
--Last year.
A. did; use B. was; used C. is; used D. are; used
[析] 彼例由下句的時(shí)間狀語(yǔ)推斷出一般過去時(shí)態(tài),并且要考慮到被動(dòng)語(yǔ)態(tài)。
本用上下白語(yǔ)意確定時(shí)態(tài)的原則
4. –Hi! Lin Tao. I didn’t see you at the party.
--Oh, I ready for the maths exam.
A. am getting B. was getting C. got D. have got
[析] 彼例由didn’t, at the party推斷出應(yīng)用過去進(jìn)行時(shí)。
