文檔簡介
1、最新 料推薦現(xiàn)在完成時與一般過去時的區(qū)別現(xiàn)在完成時與一般過去時都表示一個在過去完成的動作。它們屬于不同時間的兩種時態(tài),現(xiàn)在完成時屬于現(xiàn)在時態(tài)的范疇,而一般過去時屬于過去時態(tài)的范疇。下面我們先從構(gòu)成形式上區(qū)別一下兩種時態(tài)。現(xiàn)在完成時的動詞形式為:“(haves)+動詞的過去分詞”像 have/has done:而一般過去時的動詞形式為:“動詞的過去式”像did . 例如:Jack s mother took him to school every day when hewas in primary school.杰克在小學(xué)時他媽媽每天送他上學(xué)。Maria has never read any C
2、hinese stories.瑪利亞從未讀過中國故事。2. 基本用法不同: “對現(xiàn)在影響” 、“持續(xù)到現(xiàn)在”正如前面所說,現(xiàn)在完成時是與現(xiàn)在有關(guān)的時態(tài),屬現(xiàn)在時態(tài)的范疇,現(xiàn)在完成時與一般過去時最大的區(qū)別有兩點:它側(cè)重于過去的動作對現(xiàn)在造成的影響;而一般過去時是一種過去時態(tài),側(cè)重于表示過去的動作,與現(xiàn)在無關(guān)。例如:Yesterday I went to the zoo.昨天我去了動物園。 (僅說明昨天去了動物園,與現(xiàn)在無關(guān))Li Lei has read the book.李磊已看過那本書。 (說明李磊1最新 料推薦了解那本書的內(nèi)容)另外, 現(xiàn)在完成時還可以表示動作從過去某個時候開始一直延續(xù)到現(xiàn)
3、在,強調(diào)動作的延續(xù)性它常與for 及 since 引導(dǎo)的一段時間狀語連用。例如:He has lived here for ten years.他已在這兒住了10 年了。比較:1.)The Greens have worked in China since 1998.格林一家自1998 年到現(xiàn)在一直在中國工作。The Greens worked in China in 1998.格林一家 1998 年在中國工作。2.) He has lived in the country for a long time.他在農(nóng)村生活了很長時間。 (現(xiàn)在還在農(nóng)村)He lived in the country
4、 for a long time before he came to town.他進城前在農(nóng)村生活了很長時間。3.) She has bought a bicycle.她買了一輛自行車。 (現(xiàn)在她有一輛自行車了。 )She bought a bicycle last year.去年她買了一輛自行車。4.) He has won a prize for his invention.他因為他的發(fā)明而獲獎了。He also won a prize last year.他去年也獲獎了。注意:2最新 料推薦在與 for 及 since 引導(dǎo)的一段時間狀語連用時,句子的謂語動詞必須是延續(xù)性動詞,終止性動詞
5、不可和一段時間連用。例如:他當(dāng)兵已三年了。誤: He has become a soldier for three years.誤: He joined the army for three years.正: He has been a soldier for three years.正: He has been in the army for three years.1.連用的時間狀語不同與現(xiàn)在完成時連用的時間狀語除了上面所說明的由since 和for 引導(dǎo)的一段時間外還有:already, yet, still ,just, so far,in the last(past), before
6、, ever, never等。而一般過去時則常與 ago, yesterday, last, in 2000, just now等連用。注意:現(xiàn)在完成時態(tài)不可與yesterday, last week, two daysago 等之類的表示具體的過去時間的狀語連用。例如:Have you ever picked flowers or stepped on the grassin the park?你曾在公園里摘過花或曾踩過草地嗎?Father bought that watch ten years ago.爸爸 10 年前買了那塊手表。I have never seen the film be
7、fore.我以前沒有看過這部影片。注意:在 when引導(dǎo)的特殊疑問句中不可用現(xiàn)在完成時,而3最新 料推薦只可用一般過去時。例如:When did you visit Japan?你什么時候訪問過日本?Exercises:同步練習(xí)動詞填空:1.sawI _(see) Tom last Friday.2.Did , go_you _(go) to theGreat Wall last summer?3.When _did_ you _start_(start) tolive in China?5.-The train _ (leave) already.-When _ the train_(lea
