例题：What can be inferred about the region including Maine and Quebec during the early 1800s？

　　（A） The area was economically unified¹.

　　（B） The authorities were unable to enforce law and order.

　　（C） The two governments fought for control of the area.

　　（D） Most of the people living there spoke² only French.

　　答案是A.

　　这道题比较难，因为选项都不是原句的简单改写或者复述，你可以从短语“infer about”得到提示它是一道暗示推理题。有了这种思想准备之后，即使你一时没找到答案也不会太灰心。但是题总是要答的，甚至用猜。原对话中的句字“At the time Quebec was a major market for livestock³， crops and fish. So a road to Quebec was seen by officials in Maine as necessary for trade”说明，A是正确答案。看来，暗示推理题并不好做。然而，有幸的是，暗示推理题的正确选项与其它3个选项有较大的区别。那就是选项中很少或者根本不用原话，或者原词。就像这一题，选项A中只有一个词重复原文，即area这个很不重要的词。

　　续前续后题?

　　例题：What subject is the speaker most likely to discuss next？

　　（A） The latest practices of accurate mapmaking.

　　（B） The impact of epidemics⁴ on mass migration⁵.

　　（C） The advantages of establishing international trade agreements.

　　（D） The technology used to locate the Old Canada Road.

　　答案是D.

　　原文的开头和结尾都提到了选项D的内容：开头——“finding it again was a complex process that involved state of our technology： how the location of the roads was pinpointed⁶ was very interesting. And I'll return to it as soon as I gave you a little background information.”与结尾——“that's how it came to be lost. This brings me back to the original topic.”
