A new study finds that blacks on death row (1) of killing whites are more likely to be executed than whites who kill minorities. It also concludes that blacks who kill (2) minorities are (3) likely to be executed than blacks who kill whites. For example, there is more than a twofold greater risk that an African-American who killed a white will be executed than a white person who kills a (4) victim. A Hispanic is at least 1.4 (5) more likely to be executed (6) such an offender kills a white.
The researchers of the study believe that there are two (7) explanations.. First, prosecutors often win (8) office if they win well-publicized cases. When a black kills a white, such killings gets more (9) and this idea can be (10) by many famous cases. (11) , the court judges at the state level are often (12) to elections, called retention elections. Retention election or judicial retention within the United States court system, is a periodic process, in which the voter (13) approval or disapproval for the judges presently (14) their position, and a judge can be removed from the position if the (15) of the citizens vote him or her out. Just as the researchers (16) out, death penalty is (17) political.
The findings of the study, in short, show that American justice systems clearly (18) white lives more than those of blacks or Hispanics. The researchers also say their findings (19) serious doubts about (20) that the U.S. criminal justice system is colorblind.

A.nonwhite
B.American
C.foreign
D.minor
参考答案：A
解析：
[考点] 上下文语义
本题出在第三句，而第三句句首出现for exagmple，这就说明第三句不过是第一、二句的延伸和具体化，我们从而可以初步判定第三句要表达的意思应当与前两句保持一致，只不过是举实例说明白人的地位比其他人种更高。同样，通过than，我们可以判断出，这句话也是一个比较结构，我们首先应当找出比较的两个对象，然后找出比较的内容。这句话的主干为there is more than a twofold greater risk”存在双倍的风险”，that引导的同位语从句修饰risk，具体说明是什么样双倍的风险。如果我们去除从句中的两个who引导的定语从句，那么从句的主干就是an African-American will be executed than a white person“一个非洲裔美国人(黑人)比一个自人更……被处死”。比较的两个对象分别是：an African-American who killed a white person“一个杀死白人的非洲裔美国人”和a white person who kills a (4) victim(受害者)“一个杀死……的白人”。比较的内容就是“被处死的几率高两倍(twofold)”。
[干扰项分析] A项nonwhite“一个杀死其他人种的白人”，B项American“一个杀死美国人的白人”，C项foreign“一个杀死外国人的白人”，D项minor“一个杀死未成年人的白人”。显然只有选项A符合种族对比的意思，即“谋杀白人的美籍非裔人(黑人)”和“谋杀非白色人种的白人”形成对比。
