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。 ; h5 Y! Y7 ~/ r- G5 M
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。 ! x/ d( M# 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。

Chinese 'takes more brainpower' # Q1 M: [: m5 _. L" T- O* Q( y

- j8 z$ ~1 I2 G0 _" a  N3 y9 ZSpeaking Chinese may take more brainpower than speaking English, a study suggests. " F9 l- d; D# I2 V
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. ! j8 j/ g7 h) `

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.

The researchers believe that this area of the brain links speech sounds together to form individual words. ( k/ D$ @3 `; D3 q; s7 \

For instance, the word "ma" can mean mother, scold, horse or hemp depending on how it is said. , L$ ~5 [$ |1 u# T1 V# O# Y- G
