(我已經(jīng)看過了這部電影) I saw this film yesterday. (我是昨天看的這部電影) 2) 現(xiàn)在完成時常與模糊的時間狀語連用(如for, since, so far, ever, never, just, yet, till/until, up to now, always等),或者干脆沒有時間狀語; 而一般過去時常與具體的時間狀語連用(如yesterday, last night, …ago, in 1980, in February等)。 3) 現(xiàn)在完成時表示持續(xù)時一般使用延續(xù)性動詞(如live, teach, work, know等); 而一般過去時常使用瞬間動詞(如begin, buy, die, marry等)。如: He has lived in Hangzhou since last spring. My grandfather bought the car five years ago. 7. 易錯點辨析 1) 考生容易把一些瞬間動詞用現(xiàn)在完成時表達(dá),這是錯誤的。如: (×) He has died for two years. 他死了兩年了。 (√) He has been dead for two years. (√) He died two years ago. (×) The film has begun for 10 minutes. 電影開演十分鐘了。 (√) The film has been on for 10 minutes. (√) The film began 10 minutes ago. (×) She has married for three years. 她結(jié)婚有三年了。 (√) She has been married for three years. (√) She married Mike three years ago. 2) 考生不懂如何區(qū)分have been to和have gone to,盡管兩者均可后接地點,但have been to表示去過某地(現(xiàn)在已經(jīng)回來了),have gone to表示到某地去了(現(xiàn)在還沒回來)。如: She has been to Paris (three times). She has gone to Paris. 07 過去完成時 標(biāo)志:had + 動詞的過去分詞 1. 表示在過去的某個時間或動作以前已經(jīng)發(fā)生的動作或已經(jīng)存在的狀態(tài)。如: By the end of last week he had finished the work. He had left when I arrived. 2. 表示從過去某一時間開始,一直延續(xù)到過去另一時間的動作或狀態(tài)。如: We had not seen each other since I left Beijing. The film had been on for 5 minutes when I got to the cinema. 3. 某些表意向的動詞(如intend, think, plan, expect, hope等)的過去完成時表示主語未曾實現(xiàn)的愿望、希望、打算。如: I had intended to visit you last night, but someone called and I couldn’t get away. We had hoped that you would come, but you didn’t. 4. (虛擬語氣)在條件狀體從句或wish / would rather等后面的從句中,使用過去完成時表示與過去事實相反的主觀愿望。如: The party wouldn’t have been so perfect if you hadn’t come. I wish I had gone with you to the concert that day. 5. 過去完成時與一般過去時 1) 基本區(qū)別:過去完成時表示以過去某時間為起點以前所發(fā)生的動作或存在的狀態(tài),即過去完成時強調(diào)“過去的過去”,而一般過去時只表示以現(xiàn)在時間為起點以前所發(fā)生的事情或存在的狀態(tài)。如: He studied there two years ago.他兩年前在那兒學(xué)習(xí)(離現(xiàn)在兩年) He said he had studied there two years before.他說他兩年前在那兒學(xué)習(xí)過。(離他說話時兩年) 2) 特別注意:兩個動作如果按順序發(fā)生,又不強調(diào)先后,或者用then, and, but等連詞連接時,多用一般過去時。如: When she saw the mouse, she screamed. My aunt gave me a hat and I lost it. 08 過去將來時 標(biāo)志:would + 動詞原形 1. 表示從過去某一時間來看將要發(fā)生的動作或存在的狀態(tài),一般用于主句為過去時的賓語從句中。如: He said he would come here next Friday. I knew that he would help us when we were in trouble. 2. 表示過去的動作習(xí)慣或傾向: The old man would sit on a bench in the quite park for hours without doing anything. When I worked on that farm, I would get up at 5 am. 3. 用于虛擬語氣中: If I were you, I would not do that. If he were here, he would show us how to do it. 4. 過去將來時的其他形式 1) was / were going to + 動詞原形。如: He told us that he was going to attend the meeting. She said that I was going to be sent to meet her at the railway station. 2) was / were to + 動詞原形。如: The building was to be completed next month. Li Lei was to arrive soon. 3) was / were about to + 動詞原形。如: We were about to leave there when it began to rain heavily and suddenly. He was about to have lunch when the bell rang. 〖 親愛的們,看完記得在文末點個“在看” 〗 -來源- * 圖文來源網(wǎng)絡(luò);由公眾號:北京初中生(bjczs99)整理編輯;我們尊重原創(chuàng),如有侵權(quán)請聯(lián)系刪除,轉(zhuǎn)載時請在文首及文末注明文章出處。 * 小欣老師微信:suzanbei 好友申請備注:年級+家長/學(xué)生+地區(qū) |
