20.New research suggests that speaking more than one language may delay different kinds of dementia(癡呆),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 650people whose average age was 66.240of those studied suffered from Alzheimer's,the most common form of mental decline(下降).391of 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(執(zhí)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.

分析 文章介紹一項新的調(diào)查結(jié)果,研究表明會多種語言或能延遲癡呆的最初跡象,文章介紹調(diào)查的方式和過程,解釋其中的道理.
解答 59.B.細(xì)節(jié)理解題:從第一段的句子:New research suggests that speaking more than one language may delay different kinds of dementia(癡呆),that is the loss of mental ability.可知新研究表明說兩種語言可以延緩各種癡呆,而不是治愈,故選B.
60.A.詞義猜測題:從第二段的Researchers studied nearly 650 people whose average age was 66.240 of those studied suffered from Alzheimer's,可知subjects是指的:接受測試的人,故選A.
61.C.細(xì)節(jié)理解題:從最后一段的句子: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認(rèn)為是什么時候?qū)W習(xí)的兩種語言沒有什么影響,故選C.
62.B.推理判斷題:這篇文章講的是說兩種語言可以延緩各種癡呆,這是關(guān)于健康的話題,故選B.
點評 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力,做細(xì)節(jié)理解題時一定要找到文章中的原句,和題干進(jìn)行比較,再做出正確的選擇.在做推理判斷題不要以個人的主觀想象代替文章的事實,要根據(jù)文章事實進(jìn)行合乎邏輯的推理判斷.
