新概念英語(yǔ)第二冊(cè)語(yǔ)法總結(jié)：現(xiàn)在完成時(shí)

現(xiàn)在完成時(shí)：1.構(gòu)成：have / has + 過(guò)去分詞2.功能：(1)表示過(guò)去所發(fā)生的動(dòng)作對(duì)現(xiàn)在的影響或產(chǎn)生的結(jié)果。常與yet, just, before, recently, lately(最近), ever, never等表時(shí)間的副詞搭配使用。

►. He hasn't seen her lately.

►. I haven't finished the book yet.(2)表示一個(gè)從過(guò)去某個(gè)時(shí)間開(kāi)始，延續(xù)到現(xiàn)在并可能持續(xù)下去的動(dòng)作，常與表示一段時(shí)間的時(shí)間狀語(yǔ)連用。如：so far(迄今為止), up till now(直到現(xiàn)在), since, for a long time(很長(zhǎng)時(shí)間), up to present(直到現(xiàn)在), in the past / in the last few years(在過(guò)去的幾年里), these days(目前)……

►. He has worked here for 15 years.

►. I have studied English since I came here.

►. The foreigner has been away from China for a long time.

►. So far, I haven't received a single letter from my brother.(3)某些非延續(xù)性動(dòng)詞(即：動(dòng)作開(kāi)始便終止的動(dòng)詞)，在現(xiàn)在完成時(shí)中不能與表示一段時(shí)間狀語(yǔ)搭配。

黃金要點(diǎn)：

I.常見(jiàn)的非延續(xù)動(dòng)詞：die, arrive(到達(dá)), join(加入), leave(離開(kāi)), go, refuse(拒 絕), fail(失敗), finish, buy, marry, divorce(離婚), awake(醒), buy, borrow, lend ... (背三遍!)

II.這類(lèi)動(dòng)詞并非不能用現(xiàn)在完成時(shí)，而是不能接常由for引導(dǎo)的時(shí)間狀語(yǔ)。

III.但若是用在否定句中，非延續(xù)動(dòng)詞的現(xiàn)在完成時(shí)可以與表示一段時(shí)間的狀語(yǔ)連用。►. She has gone away for a month.(誤)

►. The man has been dead for two years.(正)►. How long have youbought the book?(誤)

►. He has been here since ten years ago.幾組對(duì)比：►. He has gone to Shanghai. 他到上海去了。

►. She is gone. 她缺席了。(或者她死了。)►. The door has been closed. 門(mén)關(guān)上了。(動(dòng)作)
