          一、一般過(guò)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。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(guò)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(guò)去時(shí)”的句型中,表示“自從……以來(lái)有……時(shí)間”的意思,主句一般用it is來(lái)代替It has been;④瞬間動(dòng)詞用于“Some time has passed since + 一般過(guò)去時(shí)”的句型中。請(qǐng)看:

          A. He joined the League two years ago.

          B. He has been in the League for two years.

          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“處于某種狀態(tài)”,如at work(在工作), at school(上學(xué)、上課)等。此短語(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(lái)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(lái)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“我就來(lái),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(lái)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.
