英语翻译
People who have lost the ability to understand or use words due to brain damage are called aphasics(失语症患者).Such patients can be extremely good at something else.From the changing expressions on speakers’ faces and the tones of their voices,they can tell lies from truths.
Doctors studying the human brain have given a number of examples of this amazing power of aphasics.Some have even compared this power to that of a dog with an ability to find out the drugs hidden in the baggage.
Recently,scientists carried out tests to see if all that was said about aphasics was true.They studied a mixed group of people.Some were normal; others were aphasics.It was proved that the aphasics were far ahead of the normal people in recognizing false speeches — in most cases,the normal people were fooled by words,but the aphasics were not.
Some years ago,Dr.Oliver Sacks wrote in his book about his experiences with aphasics.He mentioned a particular case in a hospital.Some aphasics were watching the president giving a speech on TV.Since the president had been an actor earlier,making a good speech was no problem for him.He was trying to put his feelings into every word of his speech.
But his way of speaking had the opposite effect on the patients.They didn’t seem to believe him.Instead,they burst into laughter.The aphasics knew that the president did not mean a word of what he was saying.He was lying!
Many doctors see aphasics as people who are not completely normal because they lack the ability to understand words.However,according to Dr.Sacks,they are more gifted than normal people.Normal people may get carried away by words.Aphasics seem to understand human expressions better,though they cannot understand words.

由于大脑受到伤害而失去理解能力和语言能力的人被称为失语症患者.这类病人可以在其他特定方面表现出出色的能力.假如从脸上的表情和语调的变化来判断,他们可以说谎而不被发现.研究大脑的专家已经给出了很多关于失语症患者令人惊异的能力的例子.有人些甚至觉得这种能力与狗从行李中找出毒品的能力相媲美.
近来,科学家们做了一些测试来判断关于失语症患者的说法是否正确.他们测试了一群混合的人.有一些是正常人,另外的则是失语症患者.事实证明,大多数情况下,失语症患者能比正常人快得多的辨别出有错误的讲话,正常人会被文字欺骗而失语症患者却不会.几年前,奥利弗.萨克斯博士在他的书中写到了他与失语症患者的经历.他提到一个在医院发生的特殊案例.一些失语症患者正在看总统的电视演讲.因为总统原来是一个演员,所以做一个好的演讲对他来说不是什么问题.他一直试图将他的情绪投入到他说的每一个词当中.但对于这些病人来说这种方法适得其反.他们似乎不相信他.相反,他们爆发出笑声.失语患者看出他在演讲时用错了一个词,认为他在说谎.
许多医生把失语症患者看成不完全正常的人因为他们缺乏理解文字的能力.但是,据萨克斯博士所说,他们比正常人更有天赋.正常人或许会过于关注文字,而失语症患者能却能更好的理解表情语言,虽然他们不懂得不文字.
确实很长啊...写了好久..
