The Department of Homeland Security has proposed new federal requirements for driver’s licenses that would allow them to be used as part of a national identification system. Using licenses for purposes not directly related to operating a motor vehicle is un-American because it would require U.S. citizens to carry the equivalent of “papers.” Such a requirement would allow the government to restrict their movements and activities in the manner of totalitarian regimes. In time, this could make other limits on freedom acceptable. The author assumes which of the following?
A.The next presidential election will be dishonest, as has happened in eastern European countries.
B.The government will soon start curtailing the activities of those it considers “dissidents.”
C.Blanket restrictions on law-abiding individuals are contrary to the traditions of American culture and law.
D.The majority of Americans are not willing to give up their right to travel and move about without identification.
E.Americans should resist all government regulation of their lives.
答案是:
The conclusion of this argument is that the national identification system (“using licenses for purposes not directly related to operating a motor vehicle”) is unAmerican. The basis for this claim is that such a system would allow the government to restrict the liberty of its people. The necessary assumption is one that connects restrictions on liberties to the concept of “un-American” policies.  
(A) The author never mentions future presidential elections, or the role of the president in such a national identification system. Therefore, the conclusion that the national identification system is un-American does not depend on this assumption.  
(B) Whether the government will soon, or will ever, start curtailing the activities of dissidents is irrelevant to this argument: that the national identification system is un-American simply because it restricts the liberties of U.S. citizens. Even if the government does not abuse the power the national identification system provides, the system could still be considered un-American.  
(C) CORRECT. This choice connects the concept of "un-American" policies to restrictions on liberties, essentially defining blanket restrictions on citizens as unAmerican.  
(D) Whether Americans are willing to give up their right to travel freely is irrelevant to this argument: that the national identification system is un-American simply because it restricts the liberties of U.S. citizens. Even if Americans were
willing to give up their right to move about without identification, the system could still be considered un-American.  
(E) While the author may be inclined to agree that Americans should resist the government regulation of their lives that the national identification system represents, this argument does not depend on such an assumption. In fact, the author makes a distinction between the national identification system and “licenses for purposes…directly related to operating a motor vehicle,” so it is possible that the author considers some government regulation reasonable.

题目的意思是:美国政府出台一项规定(将驾照纳入国家身份认证系统),这项规定是un-American的(这是结论)。这个规定会让政府以集权的方式限制人民。最后,有可能促成其他对自由的限制。

那么问题来了,这项规定限制自由的特性 与结论—un-American之间有什么关系呢?那么能够补全逻辑链的选项,或者能够说明二者关系的选项就可以作为备选答案。(这是assumption题的两类常见问题,逻辑链断裂,另一类是论据的正确性)

C选项说:Blanket restriction (跟法人个体相关)是有悖美国传统文化和法律的。那么就给我们提供了 一个前提,即restriction——是un-American的。刚好补全了文中逻辑所缺乏的一环,所以可以作为正确答案。

最好的方法是写逻辑链,即题目给出了什么条件然后说明了什么结论,然后再总结每个答案是从什么方面回答这些问题的,例如我总结的assumtion的两种解题类型。根据逻辑链总结出题类型,总结多了熟练度就上来,读完题就知道可以往那里想了。同时,要注意培养找结论的能力,结论如果可以很明确找到,做题会快捷很多。

有时间多看看NN们的经验也很不错,补充自己忽略的点,不过尽量以自己总结的知识体系为主。

我有一个不一样的问题。
实在看不出 Using licenses for purposes not directly related to operating a motor vehicle is un-American是结论。它看着像Premise。
这句看着像结论:Such a requirement would allow the government to restrict their movements and activities in the manner of totalitarian regimes.
这句可能是更深的结论,或者某种影响In time, this could make other limits on freedom acceptable.
高手们是怎么看出中间那句是结论的?
