  牛津 8B Unit1 復習教案

  教學目的1. To go over the knowledge in unit 1

8B牛津unit1復習教案

  教學重點和難點1. present perfect tense and some words and expressions

  教學過程

  一、重點單詞:just, since, fact, turn, miss, pleasant, land, way, lonely,

  lucky, grandpa, unkind, impolite, over, unhealthy

  二、短語運用:in fact, get married, turn into, noise pollution, take off,

  in some ways, from time to time, be in service/use, free time, on

  one’s own, on longer, the changes to;

  三、重點結構:It is easy for him to see them as often as before.

  It was built to the north of Lantau Island.

  I wish you a happy holiday.

  It no longer provides a good environment for wildlife.

  The changes have brought many benefits but they have also caused many problems for wildlife.

  四、語法:現在完成時,present perfect tense

  1、現在完成時所表示的動作發(fā)生在過去,但考慮較多的不是動作發(fā)生在過去的什么時候,而是強調與目前的聯系,即過去與現在的關系。強調過去的動作對目前造成的影響和后果,或強調動作本身或狀態(tài)持續(xù)地現在,因此屬于現在時范疇。它的主要用法可概括為八個字:影響、結果、持續(xù)和經歷。

  2、現在完成時的構成:

  肯定式:I/We/you/they have + been/ worked

  she/he/it has + been/worked

  否定式:have not +been/worked

  has not + been/worked

  疑問式:Have +主語+been/worked …?

  Has + 主語+ been/worked…?

  3、現在完成時的用法

 。1)表示過去發(fā)生的某一動作對現在生成的影響或結果。

  如:He has read the book.他已經讀過這本書了。

  “讀書”是發(fā)生在過去的動作,對現在造成的結果是“讀過了”。

  (2) 表示動作過去已經開始,持續(xù)到現在,可能還要繼續(xù)下去。這時往往與表示一段時間的狀語連用。

  如:He has worked for more than three years. 他工作三年多了。

  I have been in Suzhou for ten years. 我來蘇州已經十年了。

  (3) 現在完成時屬于現在時態(tài)范疇,不能和表示過去的時間狀語連用,如yesterday, last week, a day ago等。但可以和never, ever, already, yet, just(剛剛), for…, since…, in the past three years, so far(到目前為止), by now, before(以前)等連用。

  如:Have you finished your picture yet? 你已經完成你的畫了嗎?

  I have never heard of him before. 過去我從未聽說過他。

  (4) 瞬間動詞也叫短暫性動詞。這種動詞動作開始也就意味著結束,所以不能與表示一段時間的狀語連用。這些動詞是become, begin, start, buy, borrow, arrive, come, die, fall, finish, go, join, leave, marry 等。這了表述這種意思,我們常用相應的延續(xù)性動詞have, keep 等或短語“be+名詞/形容詞/位置副詞/介詞短語”來代替短暫性動詞。

  如:He has kept the book for three weeks. 這本書他已借了三周了。

  The meeting has been on for half an hour. 會已開始半小時了。

  He has been in the army for three years. 他參軍三年了。

 。5)其他詞組的區(qū)別

 、賡ince和for的區(qū)別

  since短語或從句表示過去的動作延續(xù)至今,since之后為時間點。如:He has lived here since 2000. 2000年以來他一直住在這兒。

  I haven’t seen him since ten years ago. 自十年前開始我就沒見過他。

  I have known him since I was very young. 我很小時就認識他了。

  For短語表示動作延續(xù)多長時間,for后面跟時間段。

  如:He has lived here for three years.他住這兒已經三年了。

  I haven’t seen her for a long time.我已經好久沒見到她了。

 、趆ave/has been in, have/has been to和have/has gone to的區(qū)別

  have/has been in表示“在某地呆了多久了”,可以與表示一段時間的狀語連用。 Have/has been to表示“曾到過某地(已回來)”,不能與一段時間的狀語連用。兩者表示的意義不同,所以跟的時間狀語也不同。

  如:He has been to Guangzhou twice. 他去過廣州兩次。

  He has been in Guangzhou for a long time. 他在廣州已呆了很長時間了。

  have/has gone to意為“到某地去了(還沒回來)”,表示到了某地或正在去的途中?傊f話時當事人不在現場,一般不用第一、第二人稱代詞作句子的主語。

  如:—Where is Kate? 凱特在哪兒?

  —She has gone to the post office. 她去郵局了。
