题文
New research suggests that speaking more than one language may delay different kinds of dementia(痴呆), that is the loss of mental ability. In fact, researchers say, speaking two languages appears to be more important than the level of education in defending against dementias.A study in India examined the effect of knowing more than one language in delaying the first signs of several dementias. Researchers studied nearly 650 people whose average age was 66. 240 of those studied suffered from Alzheimer's, the most common form of mental decline(下降). 391 of the subjects spoke two or more languages. Researchers found the dementias began about four-and-a-half years later in those who spoke two languages compared to those who spoke only one language. The level of education had no effect on the age at the first sign of dementia.
Thomas Bak, from the Center of Cognitive Aging at the University of Edinburgh in Scotland, who helped to organize the study, suggests that individuals who speak more than one language train their brains by moving back and forth between different words and expressions. He also believes this effort improves what scientists called executive(执行的) functioning, which often weakens in people with dementias. He states that researchers found there was no extra gain in speaking more than two languages.
Mr Bak says it does not appear important whether you learn another language at a young age or later in life. It's not something that “you missed the boat when you do not do it as a baby.” It is something that is still quite useful and powerful when you do it as an adult.

答案
小题1:B
小题2:A
小题3:C
小题4:B
解析
文章介绍一项新的调查结果，研究表明会多种语言或能延迟痴呆的最初迹象，文章介绍调查的方式和过程，解释其中的道理。
小题1:细节题：从第一段的句子：New research suggests that speaking more than one language may delay different kinds of dementia(痴呆), that is the loss of mental ability.可知新研究表明说两种语言可以延缓各种痴呆，而不是治愈，选B
小题2:猜词题：从第二段的Researchers studied nearly 650 people whose average age was 66. 240 of those studied suffered from Alzheimer's, 可知subjects是指的：接受测试的人，选A
小题3:细节题：从最后一段的句子：Mr Bak says it does not appear important whether you learn another language at a young age or later in life. 可知Mr Bak认为是什么时候学习的两种语言没有什么影响，选C
小题4:文章出处题：这篇文章讲的是说两种语言可以延缓各种痴呆，这是关于健康的话题，所以选B
