Here is an astonishing and significant fact: Mental work alone can’t make us tired. It sounds absurd. But a few years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue(疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day laborer, we would find it full of fatigue toxins(毒素)and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.
So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?
Some scientists declare that most of our fatigue comes from our mental and emotional(情感的)attitudes. One of England’s most outstanding scientists, J. A. Hadfield, says, “The greater part of the fatigue from which we suffer is of mental origin. In fact, fatigue of purely physical origin is rare. ”Dr. Brill, a famous American scientist, goes even further. He declares, “One hundred percent of the fatigue of a sitting worker in good health is due to emotional problems.”
What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated—those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body. What surprised the scientists a few years ago?
| A．Fatigue toxins could hardly be found in a laborer’s blood. |
| B．Albert Einstein didn’t feel worn out after a day’s work. |
| C．The brain could work for many hours without fatigue. |
| D．A mental worker’s blood was filled with fatigue toxins. |
According to the author, which of the following can make sitting workers tired?
| A．Challenging mental work. |
| B．Unpleasant emotions. |
| C．Endless tasks. |
| D．Physical labor. |
What’s the author’s attitude towards the scientists’ ideas?
| A．He agrees with them. |
| B．He doubts them. |
| C．He argues against them. |
| D．He hesitates to accept them. |
We can infer from the passage that in order to stay energetic, sitting workers need to_______.
| A．have some good food |
| B．enjoy their work |
| C．exercise regularly |
| D．discover fatigue toxins |

My mother died twice in August 2009—once on her75th birthday at a crowded restaurant, surrounded by her closest family members - and finally，the next day at a hospital. Eight months later, I began to come out of the fog of grief and depression to find a new purpose for my life.
Like many of my generation, I had lived only for myself—traveling, acquiring what I needed, rising to a position of importance and getting financial rewards. I was “kind - hearted” and “volunteered” for various causes, but really didn't give of myself.
In the spring after Mom's death, I found myself waking in the middle of the night with one thought. I wanted to offer myself as a living kidney (肾)donor. My husband Robb had received the gift of life through a kidney transplant (移植）from a deceased donor in 1999，so I was familiar with the need for donors and knew several people who were waiting for a life saving transplant. I decided to offer myself to be matched with the most suitable person on the waiting list at my local transplant center. I was paired with a 71-year-old grandmother from New Jersey who had survived for six years. At her 70th birthday, her family threw a big party as they did not expect her to live much longer. She has become my very good friend.
In donating my kidney, I extended myself in a way far beyond what I ever believed was possible. I did so in honor of my mother who sacrificed so much for me and my sisters, and in memory of my husband's donor who extended her life through him.
I encourage all who enjoy the gift of good health to share with others, either as a living donor or by donating organs upon death. By extending yourself through organ donation, you will live on through others in a magic way and give comfort to your loved ones. From the second paragraph, we can conclude that __________

Nine years ago ,after Leo had died ,people said to me ,“I never knew he was your stepfather. ” You see ,I never called him that. At first ,he was no one special in my life. Then he became my friend. In time, I felt he was my father too.
Leo married my mother when I was eleven. Two years later we moved into a house in a new suburban development, where we put down roots. At first ,our lawn was just a mud pile with wild grass ,but Leo saw bright possibilities. "We plant trees there to give us shade as well as some flowers ，” he said. And just these little touches made our lawn different from all the others here. More important, a real family was forming. Leo was becoming a full-time parent, and I was learning what it meant to have a father.
Weekday mornings when the weather was bad ,Leo often drove me to school. Having a father drop you off may have been something my classmates took for granted, but I always thought it was wonderful. Saturday mornings, we went to the hardware store ,then stepped into the five - and - ten, buying a sports magazine or something else. Some people might think that doing errands together is nothing special, but I，who had ever before spent my childhood watching other families do these everyday activities, experienced them now with extreme joy. Looking back, I realize that Leo gave me what I needed most—the experience of doing ordinary things together as a family.

Youth volunteers from Beijing University visited Songtang Hospital, a care clinic for the aged and dying patients, during the second Global Youth Service Day on April 21.
Thirty student volunteers from the university's School of International Studies sat at the beds of the patients in their specially-decorated “care huts”. They talked with them and gave massages (按摩）to patients kept in their beds.
“I felt sorry that I could not offer more to these people than talking with them and trying to cheer them up,” said Deng Yetao , 20, a third-year student. “But it occurred to me that they need more care and love than babies. Their loneliness is worse than physical pains. ”
“Even though they are suffering a lot, the majority of the elderly people want to talk to us. Each of them has a lot of life experiences and philosophies to share. Instead of doing them a favor，I felt I was gaining a valuable lesson, ” said Mao Xiaohua ,another third-year student.
Ninety-one percent of the patients will spend the last days of their lives in the clinic, according to a survey by the hospital.
Daily visits and services by social workers and youth volunteers are a very important part of their programme. A total of 330,000 Beijing students from119 universities and colleges have visited the hospital. Many continue to offer services in their spare time. Some of them volunteer to hold the hands of dying patients during the last minutes of their lives.
