六級閱讀技巧課件

1、六級閱讀技巧六級閱讀技巧大學英語六級考試（CET 6）閱讀由5%的選詞填空，10%的長篇閱讀和20%的深度閱讀構(gòu)成，而深度閱讀是考試重心之一，包括兩篇文章，做題時間為20分鐘左右，最多不能超過25分鐘，否則會影響其它題型解答的時間。大學英語六級考試（CET 6）閱讀由5%的選詞填空總分 710分 過線分 425 聽力 35% 閱讀 35% 作文 15% 翻譯 15%算分標準選詞填空 3.6分/題長篇閱讀7.1分/題仔細閱讀14.2分/題分值比例總分 710分 分值比例六級閱讀技巧課件六級閱讀技巧課件六級閱讀技巧課件3.以連字符連接的特殊詞匯。如：university-based，one-chi

2、ld。這些詞是由兩個(或三個)單詞連接的新詞，一般當成形容詞使用。三個單詞的例子如：hard-to-grasp難以理解的。這些詞也屬于低頻詞，一般不會大篇幅出現(xiàn)。需要注意的是有時候我們需要將這些詞拆開來定位，如one-child在原文中是沒有的，原文是這樣的“They often compromise by having just one child. ”這里的one child就不是整體作為形容詞使用了。4.研究、報告、書籍型詞匯，如：report，study，books等。一般來說研究、報告等內(nèi)容都是易考點，這些信息經(jīng)常出現(xiàn)在特定的段落里，所以根據(jù)這些詞匯作為關(guān)鍵詞也很容易定位。3.以連字

3、符連接的特殊詞匯。如：university-ba5.最高級，如best，worst，most等。如六級第54題，關(guān)鍵詞之一為the best solution。然而僅憑此關(guān)鍵詞我們可能無法迅速地找到答案，因為原文的表述是the most effective method，用的詞匯是完全不一樣的。這時，我們還需要增加一個關(guān)鍵詞pension，幫助我們定位。這就提醒我們在平常的閱讀中應(yīng)多關(guān)注最高級出現(xiàn)的地方，因為它常常是考點。6. 除了以上所列的承載主要信息的名詞，形容詞等。如：funding，unsteady , values，employers，older workers，reforms，sh

4、ortage，war，immigration，rich countries等。這些詞的判斷需要大家多加練習與體會。5.最高級，如best，worst，most等。如六級第5深度閱讀考生在面對六級閱讀詞匯量大、句子結(jié)構(gòu)復雜、題材多樣化這樣的難題時，如何能準確解答，關(guān)鍵在于兩點：一是如何在閱讀過程中準確在文中標記出需要查找的內(nèi)容的具體位置；二是如何在閱讀完題干之后能迅速在文中根據(jù)記憶或者閱讀時的標注找出相關(guān)內(nèi)容。如果第一方面做的很好能大大減少第二步所花的時間。深度閱讀深度閱讀以議論性的文章為主，文章脈絡(luò)清晰、整體框架明確。而且，議論性的文章并不一定要100%全部讀懂，沒有必要把每一句話的意思都弄清

5、楚，把每一個細節(jié)都掌握。4-5個問題不可能覆蓋文章中每一個細節(jié)、每一句話。解題過程中，只要找到答案，因此六級閱讀的解題過程中，通常采用的解題方法是 深度閱讀以議論性的文章為主，文章脈絡(luò)清晰、（1）瀏覽題目，推測全文主題閱讀理解的五道題目之間通常都會有隱含的邏輯聯(lián)系，所以通過第一遍的初步瀏覽，有助于把握文章所談?wù)摰闹黝}，作出簡單設(shè)想和推測。如（1）瀏覽題目，推測全文主題 1.

41、空缺的設(shè)計遵循以下原則：首句不設(shè)空，一句之中不設(shè)兩空。二、選項特點十個空格考查的全部為實詞：其中12個副詞，24個名詞，23個動詞和24個形容詞，每個正確選項都有干擾項，要么是相同詞性選項之間的相互干擾，要么是多余選項對正確選項的干擾。選項中動詞時態(tài)與文章時態(tài)一致。選詞填空一、命題形式選詞填空的命題形式近似于完形填空，即在三. 解題流程1.瀏覽全文和選項這一步的作用是讓考生了解文章的大致內(nèi)容和選項，初步做到心中有數(shù)。主要關(guān)注文章中涉及了哪方面的內(nèi)容，出現(xiàn)了哪些具體事例，其中反復出現(xiàn)的詞是幫助我們掌握文章大致內(nèi)容的重要線索。用2-3分鐘的時間瀏覽上文，我們即可抓住本文的主旨大意：文章圍繞閱讀能力

42、這個話題進行論述，并指出喜歡深度閱讀的讀者在讀書的過程中會進入一種心醉神迷的狀態(tài)，從而與文章的作者可以產(chǎn)生一種很親密的關(guān)系，緊接著又介紹了carnalreading與spiritualreading的不同之處，最后作者對如今年輕人對電子產(chǎn)品的依賴做出含蓄的批評與指正。三. 解題流程1.瀏覽全文和選項這一步的作用是讓考生 2.確定空白處詞性通讀完全文及各個選項后，我們可以很容易判斷出各個空白處的詞性，例如第36題，空格處位于mustbepainstakingly之后，且后面跟著一個由by（被，由）連接的介詞短語，由此可知此空應(yīng)填入一個動詞的被動語態(tài)，即動詞的過去分詞形式。3.仔細閱讀空白前后內(nèi)容

43、，逐一答題正常情況下，經(jīng)過上面的幾個步驟，我們就可得出大部分答案，此時文中因空格而缺失的信息也大部分都補充完整了。因此，最后一遍閱讀若發(fā)現(xiàn)不準確的地方，修改后就完成了該種題型的解答任務(wù)。 2.確定空白處詞性通讀完全文及各個選項后，我們可以四、備考策略通過分析解題流程，我們可以總結(jié)出下面幾點復習備考策略：1.掌握正確的單詞記憶方法學習單詞一定要弄清楚其具體含義和使用語境，不能只記憶其漢語意思。記憶詞匯的正確方法是在語境中記憶單詞，通過閱讀文章來記單詞應(yīng)是最佳方法，使用這類書籍記單詞的時候，請注意觀察需記憶的單詞在不同語境下的具體含義以及能否用其他的詞來替換該詞。如果通過詞匯書來記憶單詞，那么該書

44、至少應(yīng)該有英文例句，我們在記單詞的同時還應(yīng)該學習某一單詞的常用搭配。四、備考策略2.復習鞏固基本語法大家在中學階段已掌握了基本的英語語法知識，但是在實際應(yīng)用時不一定能夠運用自如。遇到這種情況，大家就需要找一本內(nèi)容全面的語法書，把有關(guān)的內(nèi)容，特別是有關(guān)句子結(jié)構(gòu)的內(nèi)容好好地復習鞏固一下。 3.做適量的練習，熟能生巧在復習備考的過程中，無論使用什么方法和技巧，都需要大家親自去實踐和運用，因為只有實踐才能出真知。只有經(jīng)過一定量的練習，考生才能對這種題型有一定的認識，才能真正找到感覺。我們對這一題型的難度判斷是：它沒有完形填空難度大。因此，只要練習量達到30篇左右，對這一題型就能有一個較好的掌握。2.復
