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。 0 x; d* ~) C7 H5 H
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。

在这项研究中,操汉语普通话和操英语的两组人接受脑部扫描。研究人员发现,人们讲英语时,靠近左太阳穴的左颞叶开始活跃。

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。
+ H# Y1 W- i* U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。* a8 o4 f8 g9 W( W6 t* a/ g" F- b

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.

They found that the left temporal lobe, which is located by the left temple, becomes active when English speakers hear English. % K/ T/ P' x& ~3 f- ]
