【托福培训-听力】“一箭双雕”，答对双选题的三个阶梯.

而32-4中的这题就“不太正常”：

　　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

　　其中有提示词提领的地方比较好判断“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.“

　　而另一处答案点则隐藏在后面的一处师生问答处

　　“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、进阶：对比型双选

　　解题关键：对比形容词

　　在听到有对比形容词的时候，如Traditional- unconventional，如Large-small ，往往代表两种性质相反的事物A，B，就会出现考察这两种事物A，B特性的双选题。如27-3中的一题，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

　　题干中就出现“small animal”和“large animal”的明显对比，而原文中则通过“fewer”“more”的数量对比来引出考点：“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、高阶：无明显提示词,练就排除易混选项的火眼金睛

　　这种情况下的双选即无明显提示词，选项答案点在原文中分布也相对分散，给我们的判断造成了很大的困难。这时，除了在听文章时要通过我们在细节题中所提到的其他重点提示词来提炼信息，更需要在解题时通过选项中的“蛛丝马迹”，来帮助我们排出正确选项，提高答题的正确率。

　　比如32-C1中的这题：

　　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

　　我们暂且不看原文，而从题干和选项所呈现的事实中来判断。这篇提问男生如何才能有“best chance”向书店卖出他的书(此处是二手书)，best chance就限定我们一定要选出一个“机会最大”的选项，也就意味着要有比较的可能性，才有最高级。逐个看选项：A.问教授是否下学期还会用同样的书。做题时可以自问：如果下学期还用一样的书，男生的机率就最大了吗?相比较其他同学卖二手书的同学，他有何优势呢?并没有。再看B.趁回购期一开始就来卖。这里就具备了比较的条件，时间“先”“后”，比别人早来，可以更快卖出书。C呢，书保存得很完好。此处的比较是书的状态“好”“坏”的对比，有对比，就有突出的可能。比别人书的状态好，就能更快卖出。所以C也说得通。D.附上书的发票。这个可以是buyback的一个必须条件，但体现不出差别，因为别的同学也可以把发票带来。

　　以上的三阶段，是关于双选题的一些思考，在解决具体题目时，同学们可以参考以上的步骤，去寻找原文和选项中的这些线索，并反复听对应的原文音频，使自己不仅知道这些技巧，而且耳朵能够迅速反应出来。
