英語(yǔ)專(zhuān)業(yè)八級(jí)是目前我國(guó)體現(xiàn)最高英語(yǔ)水平的等級(jí)考試，在備考的過(guò)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(yǔ)專(zhuān)八聽(tīng)力真題講座快速解題四大原則，大家可以作為參考。

　　1、首尾原則 眾所周知，絕大多數(shù)講座的行文方式都是由教授開(kāi)門(mén)見(jiàn)山地講述通篇的主旨，所以針對(duì)主旨題必須聽(tīng)明白的就是首段了。結(jié)尾方式則比較多樣化，時(shí)而首尾呼應(yīng)，時(shí)而深化主題，甚至有的時(shí)候會(huì)出現(xiàn)一些和開(kāi)始不一致或者相反的結(jié)論，這時(shí)主旨題的正確選項(xiàng)則應(yīng)該從結(jié)尾處對(duì)應(yīng)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(kāi)頭教授說(shuō)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? 直接明了地介紹了主旨。而結(jié)尾處的Even Proteus would be impressed, I think. 也就完美對(duì)應(yīng)了D選項(xiàng)。而其它選項(xiàng)均和防御機(jī)制完全沒(méi)有關(guān)系，自然無(wú)法選擇成為正確選項(xiàng)。

　　2、順序原則 一般來(lái)講，如果聽(tīng)到類(lèi)似基數(shù)詞“one, two, three”，或者序數(shù)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(lèi)的信息，那么這篇講座的結(jié)構(gòu)一般就可以被輕松地定性為是“總分結(jié)構(gòu)”，而且考生應(yīng)該了解，所有上述的提示詞之后必定會(huì)出現(xiàn)一個(gè)分論點(diǎn)，必須做記錄，因?yàn)閷?duì)應(yīng)會(huì)考查細(xì)節(jié)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(dāng)老師談?wù)撏暾卖~(yú)的第一點(diǎn)特征后，馬上又說(shuō)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.于是我們就知道第二點(diǎn)信息是講皮膚質(zhì)地，而且是和章魚(yú)身上的一種凸起的結(jié)構(gòu)papillae相關(guān)的，所以答案自然應(yīng)該選C。而A選項(xiàng)里面的dye染色劑是在第一段講述章魚(yú)變化顏色的時(shí)候提及的，B選項(xiàng)里面的propel推動(dòng)章魚(yú)前行則和本文重點(diǎn)章魚(yú)的變形無(wú)關(guān)，最后的D選項(xiàng)中講述大小和形狀，也與此段無(wú)關(guān)。

　　3、定義原則 一旦文章當(dāng)中出現(xiàn)了針對(duì)某個(gè)詞或者某個(gè)概念的定義性解釋?zhuān)敲催@個(gè)被解釋的詞或者概念一定我們筆記的重中之重。因?yàn)檫@個(gè)詞對(duì)于大多數(shù)考生來(lái)說(shuō)往往是一個(gè)完全陌生的概念，而且對(duì)這個(gè)詞的理解程度很可能會(huì)直接影響我們對(duì)整篇文章的理解程度，因?yàn)槲恼碌钠渌糠只蛟S就是因?yàn)檫@個(gè)概念而展開(kāi)的。很多推斷題就是基于某個(gè)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(dāng)教授為神話人物下定義的時(shí)候，說(shuō)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(shí)是為了幫助學(xué)生認(rèn)識(shí)章魚(yú)的百變能力，所以選B就顯得非常輕而易舉。而A選項(xiàng)里面的scientific科學(xué)名字和原文里的mythology神話人物可以說(shuō)是截然相反，C選項(xiàng)里面的章魚(yú)和希臘神話本身無(wú)關(guān)，只是功能和Proteus相似而已，而D選項(xiàng)里面的半人半獸則和原文信息中說(shuō)他可以時(shí)而是人樣，時(shí)而變獸形，有很大出入。

　　4、舉例原則 平時(shí)生活中我們舉例子的目的就是為了用一個(gè)具體的實(shí)例去解釋抽象的概念，在托福聽(tīng)力中也不例外。那么大家除了要聽(tīng)到“for instance, let’s take X as an example”這類(lèi)短語(yǔ)，還要留意諸如“say, it can, one typical” 這類(lèi)詞，而且一定要知道這些實(shí)際的例子到底是為了解釋哪個(gè)抽象的概念才存在的，也就是說(shuō)，一定要找出分論點(diǎn)和細(xì)節(jié)之間的對(duì)應(yīng)關(guān)系，切勿犯了張冠李戴的錯(cuò)誤。題目方面可以設(shè)置成：在題干中給出分論點(diǎn)，要求選出對(duì)應(yīng)細(xì)節(jié)的細(xì)節(jié)題;也可以設(shè)置成，在題干中給出細(xì)節(jié)，要求選出對(duì)應(yīng)分論點(diǎn)的組織結(jié)構(gòu)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(dāng)講座進(jìn)入到最后階段，也就是第三種特征時(shí)，我們聽(tīng)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(gè)例子一旦記下來(lái)就知道答應(yīng)必為AB。而C選項(xiàng)里面的ink是在前面一段講到章魚(yú)逃脫時(shí)使用的一種方法，和變形無(wú)關(guān)，D里面的coral珊瑚礁則在文章中根本沒(méi)有提及，可謂無(wú)中生有。

　　以上就是小編給大家分享的英語(yǔ)專(zhuān)八聽(tīng)力真題講座快速解題四大原則，希望可以給大家在備考的過(guò)程中帶來(lái)幫助。
