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。 9 q& ^. d* z) f/ D/ z6 g8 `
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。 ) C/ O, q! q2 P3 D: X5 X
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。
8 O3 _+ l7 j) k4 ]2 l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。
  s4 R$ t% r1 b2 u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。
6 C9 V- h6 f" N' d7 T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。
9 _$ A3 `2 D. F5 P3 I: |" ^0 I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.

Mandarin is a notoriously difficult language to learn. Unlike English, speakers use intonation to distinguish between completely different meanings of particular words.
