現(xiàn)在完成進(jìn)行時(shí)表延續(xù)的用法

現(xiàn)在完成進(jìn)行時(shí)是英語(yǔ)考試中?？嫉囊粋€(gè)語(yǔ)法點(diǎn)，它是英語(yǔ)中，動(dòng)詞的一種基本時(shí)態(tài)，其構(gòu)成為：主語(yǔ)+助動(dòng)詞（have/has）+been+動(dòng)詞的現(xiàn)在分詞+其他成分。表示動(dòng)作從某一時(shí)間開(kāi)始，一直持續(xù)到現(xiàn)在，或者剛剛終止，或者可能仍然要繼續(xù)下去。

那么,今天就跟著小編來(lái)學(xué)習(xí)下現(xiàn)在完成進(jìn)行時(shí)表延續(xù)的情況，表示表示開(kāi)始于過(guò)去的活動(dòng)持續(xù)到現(xiàn)在，并且活動(dòng)往往還沒(méi)有結(jié)束，將繼續(xù)持續(xù)下去。。

具體的用法結(jié)合句子來(lái)理解，先來(lái)看例句；

1.I have been living in Hawaii for ten years. 我在夏威夷已經(jīng)生活了十年。

2.She has been burning the midnight oil to prepare for GRE. 她最近在熬夜準(zhǔn)備GRE考試。

3.Tom has been playing the online games for more than twenty hours. 湯姆玩網(wǎng)游已經(jīng)超過(guò)二十個(gè)小時(shí)了。

4.What happened to you? Have you been crying? 你怎么了？你是不是一直在哭？

好了，通過(guò)以上的幾個(gè)例句，大家是否了解了英語(yǔ)過(guò)去進(jìn)行時(shí)表在某事發(fā)生前開(kāi)始的動(dòng)作的情況呢？

那么，接下來(lái)我們做幾道題測(cè)試下你的現(xiàn)在進(jìn)行時(shí)掌握得如何：

1.— I’m sure Andrew will win the first prize in the final. — I think so. He ________ for it for months. A. is preparing B. was preparing C. had been preparing D. has been preparing
