1. Because rap and hip-hop offer such_________commentaryon contemporary issues, they are often said to besharp-edged musical genres.

(A) nebulous

(B) trenchant

(C) circumspect

(D)prosaic

(E) benign

解析：空格填入一个形容词，修饰“评论(commentary)”，改该“评论”是由“rap and hip-hop”对“当代社会的问题(contemporary issues)”所做的“评论”。寻找相关语义找到代词“they”，指代“rap and hip-hop”，“because”表示因果关系，句子前后逻辑方向相同。因此空格应该填入“尖锐的文艺形式(sharp-edged musical genres)”的语义。答案：A 模糊不清的;B 一针见血的，鞭辟入里的;C 谨慎的;D 单调的，乏味的;E(人)仁慈的，(天气)温和的。

2. The company manager was known for both his_________and his_________: he lied frequently, but did sowith amazing flair.

(A) ambivalence . . extravagance

(B) duplicity . . panache

(C) evasiveness . . irascibility

(D) mendacity . . corruption

(E) brashness . . charisma

解析：空格1和2都填入一个名词，表示“(公司经理)company manager”的状态。冒号表示前后同义，所以空格填入后应该体现“他经常撒谎，但是却撒谎撒得很有技巧，简直是撒谎的天才(he lied frequently, but did so with amazaing flair)”。“flair”表示a skill or instinctive ability to appreciate or make good use of something，即“欣赏或者很好利用事物的技巧和天生的能力”。选项：A 矛盾;挥霍。B 欺骗;羽饰dash or flamboyance in style and action，热情，炫耀。C 逃避;易怒。D 撒谎;堕落。E 傲慢无礼;领袖气质。D的第二个空堕落不符合语义，排除。答案为B。

3. Because the candidate had switched his party allegiance immediately before the campaign, his former associates called him a_________, and even his new allies considered him an_________.

(A) recruit. . expert

(B) strategist . . imbecile

(C) deserter . . inspiration

(D) prophet . . interloper

(E) traitor . . opportunist

解析：空格1和2都填入一个名词，修饰“候选人(candidate)”。Because表示因果关系，even表示递进关系，所以应该把“在选举前立即改变了自己的党派(had switched his party allegiance immediately before the campaign)”的语义，且空格2程度要深一些。选项：A 新手;专家。B 策略家(a person skilled in strategy);傻子。C 变节者，叛逃者(to quit one's post, allegiance, or service without leave or justification);灵感。D 先知;干涉他人事务者。E 叛徒;见机行事的人(a person exploiting opportunities with little regard to principle or consequences)
