7、 has been crying for an hour.你已經(jīng)學(xué)了六年英語了。 You have been learning English for six years. 現(xiàn)在完成進行時的意義 2).表示在一段持續(xù)的時間內(nèi)動作的多次重復(fù)，而這個重復(fù)的動作在說話時并不一定在進行。 例句 They have been building the bridge for two month.He has been playing basketball since he was ten.Maggie has been teaching English for ten years. 翻譯 他已經(jīng)踢了八年足

How to distinguish the Present Perfect Tense and Present Perfect Continuous Tense現(xiàn)在完成時與現(xiàn)在完成進行時的區(qū)別1). 現(xiàn)在完成時強調(diào)動作的完成，而

9、現(xiàn)在完成進行時強調(diào)動作的延續(xù)，因此，表示動作的完成，只能用現(xiàn)在完成時，而不能用現(xiàn)在完成進行時。如：He has changed his idea. 他改變了想法。2). 在表示動作的延續(xù)時，雖然既可用現(xiàn)在完成時，也可用現(xiàn)在完成進行時，但現(xiàn)在完成進行時強調(diào)動作的進行。因此在需要明確表示動作還要持續(xù)下去時，應(yīng)用現(xiàn)在完成進行時。如：We have been studying here for two years. 我們在這兒已經(jīng)學(xué)習(xí)了兩年了。相同點：1）謂語動詞都是延續(xù)性的，如live，learn，study，wait,work,rain等。 2）都與“一段時間”連用。

10、 例句 I have been learning/learned English for ten years.I have been living/lived here since three years ago. 不同點： 1）現(xiàn)在完成時結(jié)果，現(xiàn)在完成進行時過程。 2）現(xiàn)在完成進行時帶有一定的感情色彩。 例句 He has sung for two hours.He has been singing for two hours.
