英国的研究人员发现,说汉语普通话的人可能比说英语的人用更多大脑。研究表明,说汉语普通话者讲话时同时使用大脑两边。

他们发现,大脑这个区域的功能是把发音联系起来,形成单个词汇。

汉语普通话十分难学。不同于操英语者,说汉语者使用音调区分不同词的不同意思。比如"马"音,用不同音调发音,可以是马,妈等不同的意思。3 u  D6 g0 U  Y* ^: y/ q/ v- {

Speaking Chinese may take more brainpower than speaking English, a study suggests.
" x8 Y1 I; W. y) m+ [3 \Researchers in Britain have found that people who speak Mandarin Chinese use both sides of their brain to understand the language.

This, in turn, could one day help scientists to develop better ways of helping people to re-learn languages after a stroke or similar damage to the brain.

Dr Sophie Scott and colleagues at the Wellcome Trust carried out brain scans on a group of Mandarin and English speakers. + b0 s+ t& |6 T1 g6 j+ @
