9、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(jiàn)的轉(zhuǎn)換形式:一. 一般過(guò)去時(shí)與現(xiàn)在完成時(shí)的轉(zhuǎn)換詞可改成與之相對(duì)應(yīng)的延續(xù)性動(dòng)詞及短語(yǔ),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：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；瞬間動(dòng)段時(shí)間+ since + 一般過(guò)去時(shí)"的句型中，表示肆自從以來(lái)有時(shí)間”的意思，主句 一般用 it is 來(lái)代替 11 has been ;瞬間動(dòng)詞用于“ som e tim e has passed since + 一般過(guò)去時(shí)的句型中。請(qǐng)看：a. he joined the
