     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.

2. How did the scientists study aphasics?

3. What do we learn from this text?
