2010年12月英語六級深度閱讀解析及解題步驟

　　六級閱讀由10%的快讀閱讀，5%的簡答題和20%的深度閱讀構成，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。

　　考生在面對六級閱讀詞匯量大、句子結構復雜、題材多樣化這樣的難題時，如何能準確解答關鍵在于兩點：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內容。如果第一方面做的很好能大大減少第二步所花的時間。

　　深度閱讀以議論性的文章為主，文章脈絡清晰、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——

　　(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論的主題，作出簡單設想和推測。如

　　1. The phrase “emanate from” in Paragraph 1 most probably means “________”.

　　2. Which of the following is mentioned as one of the causes of bad breath?

　　3. According to the passage, alcohol has something to do with bad breath mainly because________.

　　4. Mouthwashes are not an effective cure for bad breath mainly because________.

　　5. We can infer from this passage that________.

　　第1、5題分別為猜詞題和推論題，沒有提供任何信息。不過第2、3、4題都提到了bad breath (難聞的口氣，口臭)，因此文章談論的主題就非常清晰，對于后面的理解和解題會有幫助。

　　(2)判斷題型，確定題干關鍵詞

　　六級的深度閱讀主要考查主旨題、細節(jié)題、猜詞題、推論題和態(tài)度題等五種題型，重點考查細節(jié)題。細節(jié)題的關鍵詞主要有三類(1)顯性關鍵詞：大寫、數(shù)字、連字符單詞、序數(shù)詞等;(2)實意動詞;(3)核心名詞和生詞。這一步對于接下來的瀏覽文章圈定關鍵詞至關重要。

　　(3)跳讀文章，尋找關鍵詞

　　瀏覽文章切忌試圖弄懂文中的每一個單詞。如果逐句翻譯會影響做題的速度，而且會忽略各題區(qū)域的尋找。跳讀的目的是要整體把握一下文章脈絡，找到每道題目中的關鍵詞，從而可以確定每道題目答案的所在位置。答案在文中一般情況都是依次而下順序出現(xiàn)。

　　(4)理解區(qū)域，排除干擾項

　　根據(jù)第三步尋找的區(qū)域，進行深度的翻譯和理解，比較選項與文章的信息，注意選項的同義改寫、主動被動轉換，同時要當心偷換概念、以偏概全等陷阱，依據(jù)選項一般不過于絕對(如出現(xiàn)never, only, all)等原理，排除干擾項，最終確定答案。

　　Passage One

　　For hundreds of millions of years, turtles (海龜) have struggled out of the sea to lay their eggs on sandy beaches, long before there were nature documentaries to celebrate them, or GPS satellites and marine biologists to track them, or volunteers to hand-carry the hatchlings (幼龜) down to the water’s edge lest they become disoriented by headlights and crawl towards a motel parking lot instead. A formidable wall of bureaucracy has been erected to protect their prime nesting on the Atlantic coastlines. With all that attention paid to them, you’d think these creatures would at least have the gratitude not to go extinct.

　　But Nature is indifferent to human notions of fairness, and a report by the Fish and Wildlife Service showed a worrisome drop in the populations of several species of North Atlantic turtles, notably loggerheads, which can grow to as much as 400 pounds. The South Florida nesting population, the largest, has declined by 50% in the last decade, according to Elizabeth Griffin, a marine biologist with the environmental group Oceana. The figures prompted Oceana to petition the government to upgrade the level of protection for the North Atlantic loggerheads from “threatened” to “endangered”—meaning they are in danger of disappearing without additional help.

　　Which raises the obvious question: what else do these turtles want from us, anyway? It turns out, according to Griffin, that while we have done a good job of protecting the turtles for the weeks they spend on land (as egg-laying females, as eggs and as hatchlings), we have neglected the years spend in the ocean. “The threat is from commercial fishing,” says Griffin. Trawlers (which drag large nets through the water and along the ocean floor) and longline fishers (which can deploy thousands of hooks on lines that can stretch for miles) take a heavy toll on turtles.
