在一个低气压的时代，水土特别不相宜的地方，谁也不存什么幻想，期待文艺园地里有奇花异卉探出头来。然而天下比较重要的一些事故，往往在你冷不防的时候出现。史家或社会学家，会用逻辑来证明，偶发的事故实在是酝酿已久的结果。但没有这种分析头脑的大众，总觉得世界上真有魔术棒似的东西在指挥着，每件新事故都像从天而降，教人无论悲喜都有些措手不及。张爱玲女士的作品给予读者的第一个印象，便有这情形。 对这段话理解不正确的一项是( )。

A．张爱玲作品的问世在当时社会背景下是一个特例

B．在文艺园地里奇花异卉的出现是不能用科学和逻辑来解释的

C．大众对于张爱玲作品问世的感觉是太突兀、太奇迹

D．张爱玲作品的问世并不是偶然的，存在一定的必然性

答案

参考答案：B

解析： 这段话是翻译家傅雷评张爱玲小说时所说的话。“史家或社会学家，会用逻辑来证明，偶发的事故实在是酝酿已久的结果”说明可以用科学和逻辑解释文艺园地里奇花异卉的出现并非偶然或突兀，而是“酝酿已久”的结果，所以，B选项不正确。

单项选择题

True, some of the attacks against whites by blacks are for money and valuables. But, others ale revenge assaults by blacks for a real or imagined racial insult. It is equally true that the vast majority of violent crimes against whites are committed by whites, while the vast majority of violent crimes against blacks are committed by other blacks. Yet even after discounting crimes that are hastily and erroneously (错误地，不正确地) tagged as racially motivated, many blacks do attack whites because they all white. A 1998 Justice Department study confirmed that nearly 20% of the more than 4,000 hate crimes well committed against whites, and their attackers were blacks. The Southern Poverty Law Center also notes that there is a huge escalation in black-on- white violence from nearly none at the beginning of the 1990s.
A collection of white supermacists and rightist extremist groups have eagerly made black-on- white violence a wedge issue in their movement to paint blacks as the prime racial hate mongers in America. The New Century Foundation, an ultra-conservative think-tank, has launched a full- blown national campaign to alert whites to the danger of black hate crimes. These groups and individuals magnify hate crimes by blacks in order to back their social agenda. They oppose affirmative action programs and per hate crime laws. They downplay, or justify, the proliferation of white-supremacist-tinged paramilitary groups, police violence, and racial profiling. And they lobby hard for more prisons, police, and tougher laws.
Black-on-white violence also reinforces white fears of blacks as the ultimate menace to society. When blacks say or do nothing about these attacks, it is taken by some as a tacit signal that blacks put less value on white lives than black lives. This is a terrible price for black silence on hate crimes committed by blacks.

Besides the racially motivated crimes, there are indeed crimes committed by blacks against whites for ______.

A. job
B. family
C. money and valuables


D. promotion
