另外,这项研究还可以帮助研究人员找到更好的办法,帮助人们在中风或者脑部受到类似损害后重新学习,掌握语言技能。 ( J. F; ~7 h9 _: T5 G& F" P: W- b
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。   Q2 r9 k7 f# Y+ K. a
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。

Speaking Chinese may take more brainpower than speaking English, a study suggests. . H$ g9 N3 n0 G1 q% ?) `+ w7 ?! ~
Researchers in Britain have found that people who speak Mandarin Chinese use both sides of their brain to understand the language.

Mandarin is a notoriously difficult language to learn. Unlike English, speakers use intonation to distinguish between completely different meanings of particular words. % m' n2 O. n9 w5 T

For instance, the word "ma" can mean mother, scold, horse or hemp depending on how it is said. * U2 b7 Y7 n' y! [

The right temporal lobe is normally associated with being able to process music or tones.

"We think that Mandarin speakers interpret intonation and melody in the right temporal lobe to give the correct meaning to the spoken words," said Dr Scott.
