题目

A study of high blood pressure treatments found that certain meditation techniques and the most commonly prescribed drugs are equally effective if the selected treatment is followed as directed over the long term. Half the patients given drugs soon stop taking them regularly, whereas eighty percent of the study's participants who were taught meditation techniques were still regularly using them five years later. Therefore, the meditation treatment is the one likely to produce the best results.


Which of the following, if true, most seriously weakens the argument?


选项

A.

People who have high blood pressure are usually advised by their physicians to make changes in diet that have been found in many cases to reduce the severity of the condition.

B.

The participants in the study were selected in part on the basis of their willingness to use meditation techniques.

C.

Meditation techniques can reduce the blood pressure of people who do not suffer from high blood pressure.

D.

Some of the participants in the study whose high blood pressure was controlled through meditation techniques were physicians.

E.

Many people with dangerously high blood pressure are unaware of their condition.

解析

一项关于高血压治疗的研究发现,某些冥想技巧和最常被开具的药物如果长期按指示使用,效果相同。服用药物的患者中有一半很快就不再规律服药,而在研究中接受冥想技巧训练的参与者中有80%在五年后仍在规律使用。因此,冥想治疗可能产生最佳效果。 - **论点**:冥想治疗可能产生最佳效果。 - **论据**:药物治疗有一半患者很快不规律服药,而冥想治疗有80%的参与者五年后仍规律使用。 - **正确答案方向**:能指出冥想治疗看似效果好但实际并非如此的原因,或者指出药物治疗有其他优势等,从而削弱“冥想治疗可能产生最佳效果”这一结论。 - **A选项**:患有高血压的人通常会被医生建议改变饮食,这种改变在很多情况下已被发现能减轻病情的严重程度。 - **分析**:该选项说的是饮食改变对病情的影响,与论点中比较冥想治疗和药物治疗谁更有效无关,不能对判断起到帮助作用。 - **B选项**:研究的参与者部分是基于他们愿意使用冥想技巧而被选入的。 - **分析**:这说明参与冥想治疗的人本身就更愿意坚持冥想,所以才会有较高的坚持率,而不是因为冥想本身效果好才使得他们坚持,从侧面削弱了因为高坚持率就得出冥想治疗效果好这一结论,符合正确答案方向。 - **C选项**:冥想技巧可以降低未患高血压人群的血压。 - **分析**:选项讨论的是冥想对非高血压人群的影响,与论点中对高血压患者哪种治疗方式效果最佳无关,不能对判断起到帮助作用。 - **D选项**:研究中一些通过冥想技巧控制高血压的参与者是医生。 - **分析**:参与者的职业与冥想治疗和药物治疗哪种更有效没有直接关联,不能对判断起到帮助作用。 - **E选项**:许多患有严重高血压的人不知道自己的病情。 - **分析**:这与比较冥想治疗和药物治疗的效果没有直接关系,不能对判断起到帮助作用。 ### 答案 正确答案是:B
