LAST SET2
3. The United States has never been a great international trader. It found most of its raw materials and customers for finished products within its own borders. The terrible consequences of this situation have become apparent, as this country now owes the largest foreign debt in the world and is a playground for wealthy foreign investors. The moral is clear: a country can no more live without foreign trade than a dog can live by eating its own tail.
In order to advance her point of view, the author does each of the following EXCEPT
(A) draw on an analogy
(B) appeal to historical fact
(C) identify a cause and an effect
(D) suggest a cause of the current economic situation
(E) question the ethical basis of an economic situation

此题答案是E，我在前面的帖子也看到了解释，说the moral means 教训，我的问题是D中suggest的cause是指哪一个啊？和C中identify的那个cause（most of its raw materials and customers for finished products within its own borders）是一样的吗？另外a country can no more live without foreign trade than a dog can live by eating its own tail.，这句话应该怎么解释啊？

10. Even if a crime that has been committed by computer is discovered and reported, the odds of being both arrested and convicted greatly favor the criminal.
Each of the following, if true, supports the claim above EXCEPT:
(A) The preparation of computer-fraud cases takes much more time than is required for average fraud cases, and the productivity of prosecutors is evaluated by the number of good cases made.
(B) In most police departments, officers are rotated through different assignments every two or three years, a shorter time than it takes to become proficient as a computer-crime investigator.
(C) The priorities of local police departments, under whose jurisdiction most computer crime falls, are weighted toward visible street crime that communities perceive as threatening.
(D) Computer criminals have rarely been sentenced to serve time in prison, because prisons are overcrowded with violent criminals and drug offenders.
(E) The many police officers who are untrained in computers often inadvertently destroy the physical evidence of computer crime.

The key is D
请问这道题目怎么理解，怎么做啊？

12. “Though they soon will, patients should not have a legal right to see their medical records. As a doctor, I see two reasons for this. First, giving them access will be time-wasting because it will significantly reduce the amount of time that medical staff can spend on more important duties, by forcing them to retrieve and return files. Second, if my experience is anything to go by, no patients are going to ask for access to their records anyway.”
Which one of the following, if true, establishes that the doctor’s second reason does not cancel out the first?
(A) The new law will require that doctors, when seeing a patient in their office, must be ready to produce the patient’s records immediately, not just ready to retrieve them.
(B) The task of retrieving and returning files would fall to the lowest-paid member of a doctor’s office staff.
(C) Any patients who asked to see their medical records would also insist on having details they did not understand explained to them.
(D) The new law does not rule out that doctors may charge patients for extra expenses incurred specifically in order to comply with the new law.
(E) Some doctors have all allowing their patients access to their medical records, but those doctors’ patients took no advantage of this policy.
The key is A

cancel out the first是什么意思啊？这道题我也是没思路，总结版里的解释是去看另外一个帖子，我找不到了，如果有人找到了，能不能再贴出来让我看一下，或是麻烦你们再给我讲解一下，谢谢！

10. 即使一个通过电脑作案的罪犯被发现和告发了， 被捕和被定罪的几率大大有利于这个罪犯。
A. 准备电脑相关的犯罪诉讼花的时间比平均的时间多很多，而公诉人的工作效率是由处理完成的案件数量来评价的。
B.在大多数警察部门，警官们每两三年在不同的岗位上轮岗，这么长的时间不足以使他们成为专业的计算机犯罪调查人员。
C。在地方警察部门的审判下，大多数计算机犯罪......,他们优先考虑可见的被社区视作具有威胁性的街头犯罪。
D.计算机罪犯很少被判以需入狱服刑，因为监狱里已经关满了暴力罪犯和毒贩子。
E.许多没有受过计算机方面训练的警官常常将电脑犯罪的实物证据不可挽回的毁坏了。
只有D与定罪和被捕无关。

3.与C的cause是一样的
   那句话的意思就是把没有外贸而在自己国境内自给自足的国家比作了一直正在吃自己尾巴的狗。说这个国家不会获得比这只狗长，因为没有外贸会导致恶果，就像狗吃完自己一样。
