2012年全国硕士研究生入学统一考试英语(二)试题答案详解

2012年全国硕士研究生入学统一考试英语(二)试题答案详解Section I Use of English 1.【答案】B 【解析】从空后的句子“他们解放的人们”可以看出，空前的句子表示的应该是参加了第二次大战的男人和女人。只有serve有“服兵役”的意思，所以选B。其他都不符合题意。 2.【答案】B 【解析】空内信息应该是与hero“英雄”意思相对，后面的分句说他背井离乡，经历了很多苦难，显然这里应该是说由普通人平凡人(common man)成长为英雄，所以选B。 3.【答案】A 【解析】本题考查的是词语的搭配关系，承担战争带来的负担，应该用动词bear或shoulder，所以这里选A，bore。 4.【答案】A 【解析】necessities表示“生活必需品”，空外信息food和shelter(食物和住宿)这些就是维持生存最起码的条件。Facilities是设备设施，commodities商品，properties财产，均不符合题意。 5.【答案】C 【解析】not…but，“不是，而是”表转折，不是自愿兵，也没有高的报酬，而是一个普通人。所以选C。 6.【答案】D 【解析】这道题主要考查介词的搭配。根据up______(the best trained, bestequipped, fiercest, most brutal).enemies可以知道是起来反抗敌人，所以选D选项against。 7.【答案】C 【解析】GI。在军事上是Government Issue 的缩略语，所以，GL。这个符号就是象征着这个全称Government Issue。选C。 8.【答案】A 【解析】该句意思为，GI。这个符号出现在给士兵分发的所有物品上，hand out “分发，发放”符合题意。Turn over “移交”，bring back“带回”，pass down“传承，一代一代传下来”在句意上都说不通。 9.【答案】C 【解析】空所在句子的语境为：Joe是个普通名词，一个从未爬到社会顶层的人的名字。Manage表示再怎么经过努力，最终也未获得成功，所以选C。 10.【答案】B 【解析】结合第9题的分析可知，空所在句子实际上是进一步举例说明Joe没有取得大的成就：从来都不曾出现叫做Joe的总统、副总统、国务卿。根据句意只能选never，B。 11.【答案】D 【解析】本题考察词汇辨析。空所在的语境为：GI .Joe有_ _ 的军旅生涯，曾和德国，美国以及韩国的军队作战。由此语境确定选D，其他几项均不符合题意。 12.【答案】B 【解析】本题考察词汇辨析。空所在语境为：他身上体现着美国人的某些特色，或身上结合了美国人的诸多特性。结合语境，可知作者想表达在他身上有很多美国人的典型特色，因而选B。 13.【答案】C 【解析】本题考察词汇辨析。空所在语境为：Pyle _ _ 的士兵也本色出演了该片。结合上句对Ernie Pyle的介绍，可知为一战地记者(warcorrespondent)，确定答案C。
