问题 单项选择题

越来越多的有说服力的统计数据表明,具有某种性格特征的人易患高血压,而具有另一种性格特征的人易患心脏病,如此等等。因此,随着对性格特征的进一步分类了解,通过主动修正行为和调整性格特征以达到防治疾病的可能性将大大提高。
以下哪项最能反驳上述观点( )

A.一个人可能会患有与各种不同性格特征均有关系的多种疾病。
B.某种性格与其相关的疾病可能由相同的生理因素导致。
C.某一种性格特征与某一种疾病的联系可能只是数据上的巧合,并不具有一般性意义。
D.人们往往是在病情已难以扭转的情况下,才愿意修正自己的行为,但已为时过晚。
E.用心理手段医治与性格特征相关的疾病的研究,导致心理疗法遭到淘汰。

答案

参考答案:B

解析: 题干中根据统计发现:甲现象(某性格特征)总伴随着乙现象(某疾病)出现,因此推断,甲是乙的原因。根据B,甲和乙可能是丙(某种生理因素)的共同结果。这就有力地反驳了题干中甲和乙存在因果关系的观点。

单项选择题

People can get emotional about immigration. Bill O’Reilly, a talk-show host, devoted a recent segment to the story of an illegal alien who got drunk and accidentally killed two attractive white girls with his car. If only he had been deported for previous misdemeanours, Mr. O’Reilly raged, those girls would still be alive. Another talk-show host, Geraldo Rivera, during an on-air shout-joust(争吵) with Mr. O’ Reilly, denounced his demagogic choice of story-angle as" a sin".

President George Bush tried again this week to bring a more rational tone to the debate. He urged the new Democratic Congress to revive the immigration reforms that the old Republican Congress killed last year. His proposal was broadly the same as before. He said he wanted to make it harder to enter America illegally, but easier to do so legally, and to offer a path to citizenship for the estimated 12m illegals who have already snuck in.

The first part faces few political hurdles and is already well under way. Mr. Bush expects to have doubled the number of Border Patrol agents by the end of next year. The new recruits are being trained. And to defend against the invading legions of would-be gardeners and hotel cleaners, the frontier is also equipped with high-tech military gizmos(小发明), such as unmanned spy planes with infra-red(红外) cameras. This may be having some effect. Mr. Bush boasted that the number of people caught sneaking over the border had fallen by nearly 30% this year.

And the controversial part of Mr. Bush’s immigration package--allowing more immigrants in and offering those already in America a chance to become legal -- is still just a plan. House Republicans squashed it last year. Mr. Bush senses a second chance with the new Democratic Congress, but Democrats, like Republicans, are split on the issue. Some, notably Ted Kennedy, think America should embrace hard- working migrants. Others fret that hard-working migrants will undercut the wages of the native-born.

Mr. Bush would like to see the pro-immigrant wings of both parties work together to give him a bill he can sign. The Senate is expected to squeeze in a debate next month. The administration is trying to entice law-and-order Republicans on board; a recent leaked memo talked of substantial fines for illegals before they can become legal and" much bigger" fines for employers who hire them before they do.

The biggest hurdle, however, may be the Democrats’ reluctance to co-operate with Mr. Bush. Some figure that, rather than letting their hated adversary share the credit for fixing the immigration system, they should stall until a Democrat is in the White House and then take it all. So there is a selfish as well as a moral argument for making a deal.

The Democrats are hesitant to support Mr. Bush on this issue in that ()

A.the plan will be of no value to the Democrats

B. this issue involves political competition between parties

C. they want to wait for a democratic president to improve the plan

D. they think it is selfish for Mr. Bush to carry out the plan
