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。 % p9 O# l& a" H- |1 v7 z* `: B% M
说英语者只使用大脑一边。研究人员说,这项研究能够促进了解大脑处理语言的过程。

研究发现,人们说汉语时,左颞叶和右颞叶一起活跃。研究人员说,说不同语言时,人的大脑在以不同方式破译语言。这就推翻了长期以来的看法。 . Y# {4 _5 ]: p; Z# P* m
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。

Speaking Chinese may take more brainpower than speaking English, a study suggests.   y. C+ |" [' [7 B0 ]
Researchers in Britain have found that people who speak Mandarin Chinese use both sides of their brain to understand the language.

This compares to English-language speakers who only need to use one side of their brain.

Dr Sophie Scott and colleagues at the Wellcome Trust carried out brain scans on a group of Mandarin and English speakers.
3 E( Q& O6 V' A, i1 i" N2 ~& M5 l" z2 }0 {' s) f
They found that the left temporal lobe, which is located by the left temple, becomes active when English speakers hear English.   t' r; _1 ~* q7 P; c) e. f2 h/ \

The researchers believe that this area of the brain links speech sounds together to form individual words.

For instance, the word "ma" can mean mother, scold, horse or hemp depending on how it is said. * o/ Z6 D$ w* L, O# d9 K% ^0 a
