问题 单项选择题

一项研究对1262名67—84岁的男女参试者进行了为期3年的跟踪调查,内容涉及参试者食盐日摄入量和身体活动情况。研究人员测量了参试者的认知能力及心理健康状况。结果发现,饮食含盐量高,其认知能力下降速度最快;饮食清淡的老人,认知能力下降速度缓慢。因此,吃太咸增加患老年痴呆症的危险。
以下哪项如果为真,最能支持上述结论

A.认知功能障碍是常见的老年痴呆症症状
B.研究发现了一种老年痴呆症的致病基因,所以老年痴呆症可能有遗传性
C.许多研究证实,高盐饮食增加患高血压、胃癌等疾病的风险
D.调查显示,痴呆与人的精神状况关系密切,抑郁、易怒、悲伤等不良精神刺激容易导致痴呆的发生

答案

参考答案:A

解析: 题干由“饮食含盐量高,其认知能力下降速度最快;饮食清淡的老人,认知能力下降速度缓慢”得出“吃太咸增加患老年痴呆症危险”的结沦。A项在论据和结论之间建立了联系.从而加强了结论。B、D两项说明患老年痴呆症可能是“另有他因”.削弱了结论。C项与“患老年痴呆症危险”无关。故答案选A。

     Barbie (芭比娃娃),believe it or not,is 50 this year and she's still as popular as ever. A

doll is a doll,but Barbie illustrates how,over the last five decades,women have become a

standard for judging what freedom really means. How women are treated in different countries

tells you a lot about the politics and culture of where they live.

     The doll that every little girl wants enables young children to test their possibilities in

role playing,giving them a glimpse of what they might be when they grow up,whether to be

frivolous or serious (or both).

     But in many countries that's not an option. In Saudi Arabia,where woman can't drive or go

out publicly unless covered,Barbie is banned. They think Barbie dolls are offensive to

Islam (伊斯兰教) and a threat to morality.

     In America,she represents the swiftly changing roles of women. Barbie is fun to tease

but she's as American as miniskirts_and_pantsuits in her flexible identities and her "growth"

from model to astronaut.

      Barbie inspired a dollrevolution movement. When a Teen Talk Barbie was programmed

electronically to say "Math class is tough",she was criticized by a national women's group

and was regarded as a bad stereotype. Some of her critics also say she's a bad influence

because she's too thin and encourages anorexia,that she has run through too many

stereotypes,and that she lends too much significance to the fantasy stages of child's play.

     In some Muslim countries,substitute Barbie dolls have been developed that promote

traditional values,with their modest clothing and profamily backgrounds. They are widely

seen as an effort to resist the American dolls that have flooded the market.

     Toyseller Masounmen Rahimi welcomed the dolls,saying Barbie was "foreign to Muslim

culture" because some of the dolls have little clothing. She said young girls who play with

Barbie,could grow into women who reject Muslim values. "I think every Barbie doll is

more harmful than an American missile," Ms Rahimi said.
