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.What is so surprising about aphasics?
| A．They can fool other people. | B．They can find out the hidden drugs. |
| C．They can understand language better. | D．They can tell whether people are lying. |
How did the scientists study aphasics?
| A．By asking them to watch TV together. |
| B．By organizing them into acting groups. |
| C．By comparing them with normal people. |
| D．By giving them chances to speak on TV. |
What do we learn from this text?
| A．What one says reflects how one feels. |
| B．Aphasics have richer feelings than others. |
| C．Normal people often tell lies in their speeches. |
| D．People poor at one thing can be good at another. |
If you were to walk up to Arthur Bonner and say,"Hey,Butterfly Man,"his face would break into a smile.The title suits him.And he loves it.
Arthur Bonner works with the Palos Verdes blue butterfly(蝴蝶),once thought to have died out.Today the butterfly is coming back-thanks to him.But years ago if you'd told him this was what he'd be doing someday,he would have laughed,"You're crazy."As a boy,he used to be "a little tough guy on the streets".At age thirteen,he was caught by police for stealing.At eighteen,he landed in prison for shooting a man.
"I knew it had hurt my mom,"Bonner said after he got out of prison."So I told myself I would not put my mom through that pain again."
One day he met Professor Mattoni,who was working to rebuild the habitat(栖息地) for an endangered butterfly called EI Segundo blue.
"I saw the sign'Butterfly Habitat'and asked,'How can you have a habitat when the butterflies can just fly away?'"Bonner recalls,"Dr.Mattoni laughed and handed me a magnifying glass(放大镜),'Look at the leaves.'I could see all these caterpillars(蝴蝶的幼虫) on the plant.Dr.Mattoni explained,'Without the plant,there are no butterflies.'"
Weeks later,Bonner received a call from Dr.Mattoni,who told him there was a butterfly that needed help.That was how he met the Palos Verdes blue.Since then he's been working for four years to help bring the butterfly back.He grows astragalus,the only plant the butterfly eats.He collects butterflies and brings them into a lab to lay eggs.Then he puts new butterflies into the habitat.
The butterfly's population,once almost zero,is now up to 900.For their work,Bonner and Dr.Mattoni received lots of awards.But for Bonner,he earned something more:he turned his life around.
For six years now Bonner has kept his promise to stay out of prison.While he's bringing back the Palos Verdes blue,the butterfly has helped bring him back,too.

I entered high school having read hundreds of books.But I was not a good reader.Merely bookish,I lacked a point of view when I read.Rather,I read in order to get a point of view.I searched books for good expressions and sayings,pieces of information,ideas,themes-anything to enrich my thought and make me feel educated.When one of my teachers suggested to his sleepy tenth-grade English class that a person could not have a "complicated(复杂的) idea" until he had read at least two thousand books,I heard the words without recognizing either its irony(嘲讽) or its very complicated truth.I merely determined to make a list of all the books I had ever read.Strict with myself,I included only once a title I might have read several times.(How,after all,could one read a book more than once?)And I included only those books over a hundred pages in length.(Could anything shorter be a book?)
There was yet another high school list I made.One day I came across a newspaper article about an English professor at a nearby state college.The article had a list of the "hundred most important books of Western Civilization.""More than anything else in my life,"the professor told the reporter with finality,"these books have made me all that I am."That was the kind of words I couldn't ignore(忽视).I kept the list for the several months it took me to read all of the titles.Most books,of course,I hardly understood.While reading Plato's The Republic,for example,I needed to keep looking at the introduction of the book to remind myself what the text was about.However,with the special patience and superstition(迷信) of a schoolboy,I looked at every word of the text.And by me time I reached the last word,pleased,I persuaded myself that I had read The Republic,and seriously crossed Plato off my list.

I believe that my country,Poland,is a perfect example for a place where food is particularly important.When we were little children,we began to understand how much a loaf of bread meant to our parents—to some it might sound silly but for me the custom of kissing bread before you started cutting it was simply amazing.It’s not so common nowadays to treat food that way,since you hardly ever bake your own bread.Besides,everyone would call you crazy if you tried to kiss every bread roll before you ate them!But though we no longer make our food from scratch(起点),some customs have been kept—that’s why I feel so sorry every time I have to throw any food away—even though I no longer live with my parents and nobody would blame me for this anymore!
Many people of our nation are still working as farmers,eating what they grow and harvest and therefore enjoying everything more.It’s widely known that you value more anything that needs your effort in the first place.In most homes in Poland,especially those of farmers,the whole family would try and have their meals together—extremely difficult now,but so rewarding(值得)!You can share other members’ troubles and successes,give your children some attention,or just sit down for a moment instead of rushing through life aimlessly.Furthermore,your body,and stomach in particular will be very grateful(感激) for such a time!
In Poland,a wedding,Christmas or even a birthday is celebrated with a great meal.Women in the house get together and cook,sometimes for a few days before the event,and the extremely good or unusual food will be remembered and widely talked about.
