比如：22-3中的一題

　　According to theprofessor, what are the two main goals of Pleistocene rewinding? 【 Click on 2 answers】

　　A. To restore some evolutionary processes that ended during the Pleistocene epoch

　　B. To help prevent the extinction of certain species of megafauna

　　C. To increase populations of native animal species in the western United States

　　D. To create a living laboratory where animal interactions can be observed

　　就是采取正常引入方式：“Now, the advocates of Pleistocene rewilding cite two main goals. One is to help prevent the extinction of some endangered megafauna by providing new refuges, new habitats for them. The other is to restore some of the evolutionary and ecological potential that has been lost in North America.”

　　而32-4中的這題就“不太正�！保�

　　According to the professor, what interior features of the house Irwin designed were especially beneficial? [Choose two answers]

　　A. Circular rooms with windows in the ceiling

　　B. Floors that were easy to clean

　　C. A large, spacious common area

　　D. A single-fireplace system that heated the entire house

　　其中有提示詞提領(lǐng)的地方比較好判斷“Yeah. The rooms inside the house were also hexagonal, six-sided. Hen. So one important thing was that the rooms were arranged around a chimney in the center of the house, which could provide heat for the whole house through flues, uh, small air passageways into each room, as opposed to having a fireplace in every room, which would require more cleaning and make the air inside the house dirtier.“

　　而另一處答案點則隱藏在后面的一處師生問答處

　　“Professor：OK. Think about cleaning. What part of a room is usually the hardest to clean? Like...to sweep with a broom.

　　Student：Oh! The corners. Because in square or rectangular rooms, the corners are at 90 degree angles. It’s hard to reach all the dust that gathers in the corners. But if Irwin's rooms were closer to a circle than a square, it would be easier to reach all the dust and dirt with a broom. Right?

　　Professor：Exactly.”

　　二、進階：對比型雙選

　　解題關(guān)鍵：對比形容詞

　　在聽到有對比形容詞的時候，如Traditional- unconventional，如Large-small ，往往代表兩種性質(zhì)相反的事物A，B，就會出現(xiàn)考察這兩種事物A，B特性的雙選題。如27-3中的一題，Compared to small animals, what disadvantages do large animals typically have? Click on 2 answers

　　A. large animals require more food

　　B. large animals have fewer offspring

　　C. large animals use relatively more energy in digesting their food

　　D. large animals have greater difficulty staying warm

　　題干中就出現(xiàn)“small animal”和“l(fā)arge animal”的明顯對比，而原文中則通過“fewer”“more”的數(shù)量對比來引出考點：“Biologically speaking, sauropods shouldn’t have been successful. Large animals like elephants, say, they require much more food and energy and have fewer offspring than smaller animals.”

　　三、高階：無明顯提示詞,練就排除易混選項的火眼金睛

　　這種情況下的雙選即無明顯提示詞，選項答案點在原文中分布也相對分散，給我們的判斷造成了很大的困難。這時，除了在聽文章時要通過我們在細節(jié)題中所提到的其他重點提示詞來提煉信息，更需要在解題時通過選項中的“蛛絲馬跡”，來幫助我們排出正確選項，提高答題的正確率。

　　比如32-C1中的這題：

　　What does the woman suggest the man should do to have the best chance of selling his book to the bookstore? [Choose two answers]

　　A. Ask his professor if the same book will be used next semester

　　B. Sell the book back as soon as the buyback period begins

　　C. Make sure the book is in good condition

　　D. Bring the original sales receipt with the book

　　我們暫且不看原文，而從題干和選項所呈現(xiàn)的事實中來判斷。這篇提問男生如何才能有“best chance”向書店賣出他的書(此處是二手書)，best chance就限定我們一定要選出一個“機會最大”的選項，也就意味著要有比較的可能性，才有最高級。逐個看選項：A.問教授是否下學(xué)期還會用同樣的書。做題時可以自問：如果下學(xué)期還用一樣的書，男生的機率就最大了嗎?相比較其他同學(xué)賣二手書的同學(xué)，他有何優(yōu)勢呢?并沒有。再看B.趁回購期一開始就來賣。這里就具備了比較的條件，時間“先”“后”，比別人早來，可以更快賣出書。C呢，書保存得很完好。此處的比較是書的狀態(tài)“好”“壞”的對比，有對比，就有突出的可能。比別人書的狀態(tài)好，就能更快賣出。所以C也說得通。D.附上書的發(fā)票。這個可以是buyback的一個必須條件，但體現(xiàn)不出差別，因為別的同學(xué)也可以把發(fā)票帶來。
