汉语是我们的母语，我们爱汉语， 我们要学好汉语， 我们也要我们的下一代学好汉语！

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。
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。
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。
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。

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.
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.
