Ask & Learn聞問切英語口語:Is Going to Have Been Painted

讀者 Eric 寄來句子 "The mural is going to have been being painted by the famous artist for over 6 months by the time it is finished"。Eric想問句中的 "is going to have been being painted" 是屬于什么時(shí)態(tài)？

首先，解答 Eric 的問題前，我猜being應(yīng)該是個(gè)筆誤。可以略去。

我們現(xiàn)在把這組動(dòng)詞分析一下。 is going to 的作用相當(dāng)于助動(dòng)詞的 will 或 shall，屬于 future tense。Have been painted 是 have painted 的 passive voice（被動(dòng)式），而 have painted 屬于 present perfect tense。我們?nèi)绻丫渥痈膶?，就變?"The mural will have been painted by the famous artist..."。

這個(gè)動(dòng)詞很明顯屬于 future perfect tense，只不過以 passive voice 的形式表達(dá)而已。

Future perfect tense 的用法是表示在將來某一時(shí)刻已經(jīng)完成的動(dòng)作。在 Eric 的例句中，這個(gè)將來的時(shí)刻就是壁畫完成之日，到了那天，這著名的畫師將會(huì)花了六個(gè)月的時(shí)間在這壁畫上了。
