英語專八聽力真題解題四大原則
英語專業八級是目前我國體現最高英語水平的等級考試，在備考的過程中掌握技巧可以提高效率。下面是小編給大家分享的英語專八聽力真題講座快速解題四大原則，大家可以作爲參考。
1、首尾原則 衆所周知，絕大多數講座的行文方式都是由教授開門見山地講述通篇的主旨，所以針對主旨題必須聽明白的就是首段了。結尾方式則比較多樣化，時而首尾呼應，時而深化主題，甚至有的時候會出現一些和開始不一致或者相反的結論，這時主旨題的正確選項則應該從結尾處對應獲得。
1. What is the lecture mainly about?
A. Different kinds of color vision in sea animals.
B. Differences in appearance between various species of octopus.
C. Ways that octopuses attract their prey.
D. Ways that octopuses protect themselves from predators.
文章開頭教授說的第一句話OK, now I want to talk about an animal that has a fascinating set of defense mechanisms. And that’s the octopus, one of the unusual creatures that live in the sea. The octopus is prey to many species, including humans, so how does it escape its predators? 直接明瞭地介紹了主旨。而結尾處的Even Proteus would be impressed, I think. 也就完美對應了D選項。而其它選項均和防禦機制完全沒有關係，自然無法選擇成爲正確選項。
2、順序原則 一般來講，如果聽到類似基數詞“one, two, three”，或者序數詞“first, second, third”，亦或像邏輯順序詞“to start off, to begin with, and, another, also, something else”。還有“yet another, last but not least, that’s when the concept of X comes into the picture”之類的信息，那麼這篇講座的結構一般就可以被輕鬆地定性爲是“總分結構”，而且考生應該瞭解，所有上述的提示詞之後必定會出現一個分論點，必須做記錄，因爲對應會考查細節題。
2. What does the professor say about the function of the papillae?
A. They produce dye in different colors.
B. They propel the octopus through the water.
C. They change the texture of the octopus’ skin.
D. They help the octopus contract into a smaller shape.
當老師談論完章魚的第一點特徵後，馬上又說So, that’s how octopus mimic colors, but they don’t just mimic the colors in their environment. They can also mimic the texture of objects in their environment. They have these little projections on their skin that allow them to resemble various textures. The projections are called papillae.於是我們就知道第二點信息是講皮膚質地，而且是和章魚身上的一種凸起的結構papillae相關的，所以答案自然應該選C。而A選項裏面的dye染色劑是在第一段講述章魚變化顏色的時候提及的，B選項裏面的propel推動章魚前行則和本文重點章魚的變形無關，最後的D選項中講述大小和形狀，也與此段無關。
3、定義原則 一旦文章當中出現了針對某個詞或者某個概念的定義性解釋，那麼這個被解釋的詞或者概念一定我們筆記的重中之重。因爲這個詞對於大多數考生來說往往是一個完全陌生的概念，而且對這個詞的理解程度很可能會直接影響我們對整篇文章的理解程度，因爲文章的其它部分或許就是因爲這個概念而展開的。很多推斷題就是基於某個定義而考查的。
3. Why does the professor first mention Proteus?
A. To explain how the octopus got its scientific name.
B. To introduce the octopus’ exceptional abilities.
C. To point out that the octopus played an important role in Greek mythology.
D. To provide an example of a mythological character that was part animal and part human.
當教授爲神話人物下定義的時候，說到Proteus was a God in Greek mythology who could change form. He could make himself look like a lion or a stone or a tree, anything you wanted, and he could go through a whole series of changes very quickly. Well, the octopus is the real world version of Proteus.其實是爲了幫助學生認識章魚的百變能力，所以選B就顯得非常輕而易舉。而A選項裏面的scientific科學名字和原文裏的mythology神話人物可以說是截然相反，C選項裏面的章魚和希臘神話本身無關，只是功能和Proteus相似而已，而D選項裏面的半人半獸則和原文信息中說他可以時而是人樣，時而變獸形，有很大出入。
4、舉例原則 平時生活中我們舉例子的目的就是爲了用一個具體的實例去解釋抽象的概念，在託福聽力中也不例外。那麼大家除了要聽到“for instance, let’s take X as an example”這類短語，還要留意諸如“say, it can, one typical” 這類詞，而且一定要知道這些實際的例子到底是爲了解釋哪個抽象的概念才存在的，也就是說，一定要找出分論點和細節之間的對應關係，切勿犯了張冠李戴的錯誤。題目方面可以設置成：在題幹中給出分論點，要求選出對應細節的細節題;也可以設置成，在題幹中給出細節，要求選出對應分論點的組織結構題。
4. What two examples does the professor mention to describe the octopus’ ability to change its shape? Click on 2 answers
A. A small round stone
B. The leaves of a plant
C. A cloud of ink
D. A piece of coral
當講座進入到最後階段，也就是第三種特徵時，我們聽到The muscular system of the octopus enables it to be very flexible to assume all sorts of shapes and postures. So it can contract into the shape of a little round stone, and sit perfectly still on the seafloor. Or it can nestle up in the middle of a plant and take the shape of one of the leaves.兩個例子一旦記下來就知道答應必爲AB。而C選項裏面的ink是在前面一段講到章魚逃脫時使用的一種方法，和變形無關，D裏面的coral珊瑚礁則在文章中根本沒有提及，可謂無中生有。
