Many psychologists in the early twentieth century believed that humans use only 10 percent of their brains, and even the great Albert Einstein once wrote that most people use only a small portion of the grey matter between their ears. It’s a theory that has often been put forward in television documentaries; magazines, advertisements and books over the past century.
But nearly all scientists now agree the 10 percent theory is completely unfounded. In fact, they question how this figure was ever arrived at in the first place and what areas of the brain are supposed to be unneeded. The theory supposes that if 90 percent of the brain were removed, a person would Still be able to function normally, while in reality it is known that damage to even a small area of the brain can result in extremely serious physical injury different activities and that many areas of the brain are used at the same time for some complex activities or thought processes.
Throughout the course of one day, most .areas of the brain are active at some time, even during sleep. The 10 percent theory suggests that certain areas o’ the brain are not used, but scans slow activities throughout the entire brain and not in any separate part. The final argument against the 10 percent theory is the fact that doctors carefully map the brain before removing brain cancers so that they don’t affect other essential areas.
From an evolutionary point of view, it’s highly unlikely butt our comparatively larger brains would have evolved from our ancestors if the extra areas were not needed. In fact, there is absolutely no evidence support the 10 percent theory.

It was only 5 o’clock in the morning. The house was quiet and Tim' s mother was still asleep. Only the sound of the big freezer broke the quiet. He’d dreamt of the cave last night. The purring (轻微颤动声) of the freezer had been the sea.                                         
Tim pulled on a sweater and put some apples into his schoolbag. It was too early for breakfast. He' d eat after he' d been through the cave, sitting on the rocks and staring at the sea.
He wished he had a proper pack. His schoolbag would have to do. What else? Sandwiches-but his mother might wake up if he started pulling out bread for sandwiches, she’d want to know why he had to leave so early. He settled for some biscuits, and left a note stuck to the table:
Gone to Michael’s. Back tonight, Tim.
The sky was high and soft and light outside, though the sun still wasn't up. Even the highway up the hill was quiet as he made his way down the street. The wind from the sea was fresh and sweet.
The sand hills still breathed heat from yesterday’s sun, though the top of the sand was cool. He ran down to the beach impatiently, but there was no one, just dry sand dancing in the early wind and seabirds marching up and down watching the waves.
The light changed suddenly. The first rays of sunlight stretched (延伸) across the sea. The sun was pushing its way over the edge of the world.
Over the first rocks, along to the point, Tim glanced back. The beach was still empty. The sun sailed higher in the sky.
He could see the cave now, even darker in the morning light. The sand turned silver then dark gold as the water flowed away from it. He had to force himself to go closer. Why was it so much more mysterious (神秘的) now? But it would be silly to go back now after so much trouble. He needn't go in all the way...

Visitors can find a small, old house called the O. Henry Museum in central Austin, Texas. William Sydney Porter(1862-1910)----better known as O. Henry, was one of America’s best loved writers of short stories. Beginning in 1893, he lived here. It was saved from destruction, moved, and turned into a museum in 1934. The museum is a good way to learn about the interesting life of him.
William Porter rented this house and lived with his wife and daughter for about two years. Many objects in the museum belonged to the Porters. Others did not, but are in the house to recreate the way it looked during their lifetime.
Porter worked at a pharmacy, farm, land office and bank. He also loved words and writing. The museum has special proof of Porter’s love of language---his dictionary. It’s said that he read every word in it. Porter started a small publication called “The Rolling Stone”. He wasn’t being published early on, so he published himself. His funny stories, poems, and drawings were published in the magazine. But it was too costly to continue for long, so he closed the project after about one year.
Other troubles would lead the Porters to leave Austin. Porter was accused of financial wrongdoing at the bank and lost his job. Fearing a trial, he fled the country. But he returned because his wife was dying. After her death, he faced trial and was found guilty. He served three and a half years in a federal prison in Ohio.
Porter would keep his time in prison a secret. But there was one good thing about it. It provided him with time to write. By the time of his release, he had published 14 stories and was becoming well-known as O. Henry.
Porter would later move to New York City and find great success there. He published over 380 stories in the last eight years of his life.

When we donate blood, a small amount is usually taken in advance for at least ABO and Ph systems typing. If you are O+, the O is your ABO type and the + is your Rh type. It is possible to be A, B, AB, or O as well as Rh + or Rh-.

The ABO system was discovered by Karl Landsteiner in the early 1900s. He was awarded the Nobel Prize for his achievements. There are four basic types of blood in the ABO system: A, B, AB and O. Everybody is born with one of these four types of blood. We get blood type, just like hair color and height from parents. Because of the substances(物质) contained in each type, the four groups must be transfused carefully, If two different blood types are mixed together, it may put a person into an extremely dangerous situation. Basically, A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. In an emergency, type O blood can be given because it is most likely to be accepted by all blood types, so it is often called the universal donor. However, there is still a risk. For the opposite reason, AB is sometimes called the universal receiver. However, because there can be so many reactions in the blood bank of the hospital.

There is a relationship between your blood type and your nationality. Among the Europeans, about 45 percent have type O while 42 percent have type A. The rarest is type AB. Other races have different percentage. For example, some American Indian groups have nearly 100 percent type O out of 100 donors in the world…

84 donors are Rh+	16 donors are Rh-
38 are O+	7 are O-
34 are A+	6 are A-
9 are B+	2 are B-
3 are AB+	1 is AB-

1. Which of the following shown the correct relationships in blood transfusions?

 

  A B  A         B    A       B      A      B

 

 

 AB O   AB     O      AB     O     AB      O

      A             B            C               D

 

2. The underlined word “transfuse” most probably means ________.

  A. to put the blood into a container

  B. to move the blood from one place to another  K^S*5U.C#O

  C. to put the blood of one person into the body of another

  D. to give power to another person

3. The writer suggests that the third most common blood type among the Europeans is ______.

  A. B           B. A            C. AB          D. O

4 The text mainly tells us ______.

  A. about the basic types of human blood

  B. what kind of blood is the most common

  C. about Karl Landsteiner who won the Nobel Prize

  D. the relationship between blood type and nationality

 

I opened my new patient's chart and headed for her room. My son, Eric, had just brought home a disappointing report card, and my daughter, Shannon, and I had argued again about her getting a driver's license. For the next eight hours I wanted to throw myself into helping people who I knew had much more to worry about than I did. Rebekah, mother of three lovely little girls, was only 32, admitted for chemotherapy after breast-cancer surgery, When I gave her an injection, Rebekah shut her eyes tightly and murmured a prayer until it was over. Then she smiled and squeezed my hand. “Before you go, could you get my Bible from the table?" I handed her the worn book. "Do you have a favorite Bible verse?" she asked. "Jesus wept. John 11: 35." "Such a sad one," she said. "Why?""It makes me feel closer to Jesus, knowing he also experienced human sorrow." Rebekah nodded thoughtfully and started flipping through her Bible as I shut the door quietly behind me.

During the following months, her hospital stays became frequent and she worried about her children. One day when I entered her room, I found her talking into a tape recorder. She picked up a notebook and held it out to me. "I'm making a tape for my daughters, " she said. I read the list on her pad: starting school, confirmation, turning 16, first date, graduation. While I worried how to help her deal with death, she was planning for her children's future. She usually waited until the early hours of the morning to record the tapes so she could be free from interruptions. She filled them with family stories and advice，trying to cram a lifetime of love into a few precious hours. Finally, every item in her notes had been checked off and she entrusted the tapes to her husband.

I often wondered what I would say in her place. My kids joked that I was like an FBI agent, with my constant questions about where they’d been and who they’d been with. Where, I thought, are my words of encouragement and love?

It was three o'clock one afternoon when I got an urgent call from the hospital. Rebekah wanted me to come immediately with a blank tape. She was breathing hard when I entered her room. I slipped the tape into the recorder and held the microphone to her lips. "Ruthie, Hannah, Molly, this is the most important tape." She held my hand and closed her eyes. "Someday your daddy will bring home a new mommy. Please make her feel special. Show her how to take care of you. Ruthie, honey, help her get your Brownie uniform ready each Tuesday. Hannah, tell her you don't want meat sauce on your spaghetti. Molly, don't get mad if there's no apple juice. Drink something else. It's okay to be sad, sweeties. Jesus cried too. He knows about sadness and will help you to be happy again. Remember, I'll always love you. I shut off the recorder and Rebekah sighed deeply. "Thank you, Nan, "You'll give this one to them, won't you?" she murmured as she slid into sleep.

A time would come when the tape would be played for Rebekah's children, but right then, after I smoothed Rebekah's blanket, I got in my car and hurried home. I thought of how my Shannon also liked her sauce on the side and suddenly that quirk, which had annoyed me so many times, seemed to make her so much more precious. That night the kids didn't go out; they sat with me long after the spaghetti sauce had dried onto the dishes. And we talked, without interrogations, without complaints，late into the night.
