2012英语一真题详细解析(转自考试吧跨考：2012年考研英语一答案及解析)
Section Ⅰ Use of English 2012年的完型填空是有关美国司法官伦理和政治关系的一篇文章，出自New York Times, June, 30th , 2011的“Ethics, Politics and the Law”一文。选材回归了2000年完型曾出过的法律类文章，而且和当年一样，也是包含几个小段落，不像以往的文章，三段或者四段论，脉络比较清晰，结构容易把握。而且，较去年比较“平易近人”的文章，这篇法律类文章背后有一定的背景知识，比较关注时事或者对这一块儿有所了解的同学，会相应得心应手一些。另外，20道题目中，多达13题都是在考查动词，虽然选项中基本不存在干扰项，除了15题一道考查两词的辨析之外，其他的选项含义都差别甚远，按理说值得高兴。但是这些考查动词的题目中，许多都考查对于熟词僻义的掌握情况，往年就是08年出现了3处，今年也出现3处。仅有2道题考查逻辑词，而且这两道题是送分题，不需要考虑太多。一向是命题人偏爱的以“able”作后缀的形容词依然出现(19题)。下面就真题作一个详细解析。 和以往一样，第一句话不设空，帮助同学们理解全文探讨的话题：美国高等法庭司法官的伦理道德问题。 题1选B。maintain. 此空有赖于对后文的理解。这直接体现了我们作完型的整体思路，也就是首先通读全文。尤其是看到最后一段直接给出提议：希望法官和政治划清界限从而保证自己的权威性，因此全文的导向和逻辑就非常清晰了。同时，题2答案(when)也顺势而出：如果法官们和政治家一样，法庭就不能捍卫自己作为法律卫道士的权威。 题2选A。这里的when其实表示条件关系，即“如果……。” 题3选择 weakened。上下文语义题+词义辨析。选项含义差别较大，要求对上下文逻辑关系掌握清楚。Yet表示一个转折：“即使这样，还是有很多法官这样做，损害了法庭独立和公正的名声。” 本题如果能把导向把握准，即可定位在B和D两项，D项eliminated 过于绝对，排除。 题4 选 D. accepted。上下文语义。依然是通过上下文逻辑关系，按段精度解题。这段用两个法官参与政治事件的例子说明他们的行为使得法院的裁决不偏不倚而被认可变得不太可能。A选项challenged 和C项suspected意义相反，和主旨矛盾，即肯定了法官参与政治行为。B项compromised “调停” 和主题无关。 题5 选C。上下文语义题。本段属于总分形式。首先提出法官参与政治导致的问题，然后分析问题的原因：“这种情况有一部分是由于法官们不受伦理道德准则的约束。” 其他三项不合逻辑，均不具干扰性。 题 6 选B。完型填空在历史上对于subject这个词一向情有独钟。04年，05年，08年以及10年选项中都出现，只有05年落选。而且这3年考查的意思都一致，即“易遭受……”，考查形式有“is subjected to”，“is subject to” 以及“subject sb. to sth。(使得某人容易遭受)”。今年依然是“subject”入选，但是这次取了大家最熟悉的意思，即“使服从，受…管制”，“法院应该依行为准则办事”。至于选项 A resistant 和 C immune 两个选项和subject 这三个词在04年的第8道题也同时出现。“Be immune to”指“对…免疫，不起作用”。可见很多时候命题人不总以内容为基础来设置干扰选项，也提醒大家要重视对于历年真题的复习。

(10 points) Many theories concerning the causes of juvenile delinquency (crimes committed by young people) focus either on the individual or on society as the major contributing influence. Theories 21on the individual suggest that children engage in criminal behavior 22they were not sufficiently penalized for previous misdeeds or that they have learned criminal behavior through 23with others. Theories focusing on the role of society suggest that children commit crimes in 24to their failure to rise above their socioeconomic status, 25as a rejection of middle-class values. Most theories of juvenile delinquency have focused on children from disadvantaged families, 26 the fact that children from wealthy homes also commit crimes. The latter may commit crimes 27 lack of adequate parental control. All theories, however, are tentative and are 28to criticism. Changes in the social structure may indirectly 29juvenile crime rates.
