阅读理解Here is an astonishing and significant fact: Mental work alone can’t make us tired. It sounds absurd. But a 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 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 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.
1.What surprised the scientists a few years ago?
A. Fatigue toxins could hardly be found in a laborer’s blood.
B. The brain could work for many hours without fatigue.
C. Albert Einstein didn’t feel worn after a day’s work.
D. A mental worker’s blood was filled with fatigue toxins.
2.According to the author, which of the following can make sitting workers tired?
A. Challenging mental work. B. Endless tasks.
C. Unpleasant emotions. D. Physical labor.
3.What’s the author’s attitude towards the scientists’ idea?
A. He argues against them. B. He doubts them.
C. He agrees with them. D. He hesitates to accept them.
4.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

阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项
Nola is a 41-year-old northern white rhino(犀牛) that lives at the San Diego Zoo Safari Park in Escondido, California. She is one of only four remaining northern white rhinos in the world, and the only one in the western part of the earth. The other three live in Kenya(肯尼亚).
Rhinos have lived on earth for more than 40 million years, but they are now at the risk of dying out. Hunters illegally hunt rhinos for their horns(角), which are used for art, jewelry, and decorations. They sell the horns for thousands of dollars per pound, though it is not allowed by law. Rhino horns are also prized as a key part in traditional medicine, even though scientific tests have proven that the horns cannot cure illnesses. Experts say that every eight hours, one rhino will be hunted.
Scientists are trying to find ways to prevent rhinos from dying out. In 1975, the San Diego Zoo Institute for Conservation Research started the Frozen Zoo, a program through which researchers have collected cell samples(细胞样品) from more than 8,000 different animal species until now, including the northern white rhino. Scientists hope that by studying the rhino cells, they will gain greater understanding of the species, and will find ways to increase its number.
Jeanne Loring works with the Frozen Zoo. Loring’s research focuses on pluripotent stem cells, which are cells that can renew and become any cell type. Loring’s lab at TSRI is working together with scientist Oliver Ryder of the San Diego Zoo to use pluripotent stem cells to try to increase the number of the northern white rhino. Loring said the goal is to start producing new rhinos through this method over the next couple of years.
1.We know from Paragraph 1 that northern white rhinos __________.
A. can live a very long life
B. will die out within a few years
C. have become seriously endangered
D. mainly live in the western part of the earth
2.What can we learn about rhinos from Paragraph 2?
A. Their meat is of great value.
B. They haven’t attracted much attention.
C. Their horns have been used to save lives.
D. Human activity greatly reduced their number.
3.What was the Frozen Zoo started for?
A. Studying the rhino cells.
B. Collecting cell samples from plants.
C. Preventing rhinos from being hunted.
D. Studying animals to help them survive.
4.We learn that pluripotent stem cells __________.
A. can be easily stored
B. don’t exist in all animals
C. can reproduce in a new form
D. are dangerous to normal cells

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Since the day of its birth, the United Nations has been the subject of much debate.
1. Others think that it is too weak. We can better understand this debate if we learn more about the U.N. and its history.
The U.N. was started for two reasons. First, when the idea was born, people all over the world were tired of war. They felt that there must be peaceful answers to the world’s problems.
2.
The second reason was that modern science had developed new bombs and airplanes.
3. National borders were beginning to lose their meaning. Science would develop even more dangerous weapons in the future. Only an international organization would be able to control modern science.
Franklin D. Roosevelt, U.S. President at the time, believed that the Allies (联盟) should plan for peace before the war ended. On December 1, 1943, Roosevelt, Britain’s Winston Churchill and Joseph Stalin from Soviet Union agreed to start an organization for world peace.
4.
During the next year and a half, the idea of such an organisation was debated around the world. Then came the big day. On April 11, 1945, the first international meeting of the United Nations took place in San Francisco. The goal of the meeting was to write the U.N. Charter (宪章). All of the fifty-one nations at the meeting had their own ideas to offer for the Charter.
5. Every nation present voted for the Charter. No one voted against it.
A. The U.N. Charter is a beautiful piece of writing.
B. After a long debate, a final Charter was agreed upon.
C. Even the smallest country on earth can have its voice heard.
D. They asked all countries, large and small, to join the organization.
E. These weapons made it almost impossible for a country to defend itself.
F. Some people attack the organization because they think it is too powerful.
G. They also felt that only an international organization could keep world peace.

Papa, as a son of a dirt-poor farmer, left school early and went to work in a factory, for education was for the rich then. So, the world became his school. With great interest, he read everything he could lay his hands on, listened to the town elders and learned about the world beyond his tiny hometown.“There’s so much to learn,” he’d say. “Though we’re born stupid, only the stupid remain that way.” He was determined that none of his children would be denied (拒绝) an education.
Thus, Papa insisted that we learn at least one new thing each day. Though, as children, we thought this was crazy, it would never have occurred to us to deny Papa a request. And dinner time seemed perfect for sharing what we had learned. We would talk about the news of the day; no matter how insignificant, it was never taken lightly. Papa would listen carefully and was ready with some comment, always to the point.
Then came the moment—the time to share the day’s new learning.
Papa, at the head of the table, would push back his chair and pour a glass of red wine, ready to listen.
“Felice,” he’d say, “tell me what you learned today.”
“I learned that the population of Nepal is ....”
Silence.
Papa was thinking about what was said, as if the salvation of the world would depend upon it. “The population of Nepal. Hmm. Well….” he’d say. “Get the map; let’s see where Nepal is.” And the whole family went on a search for Nepal.
This same experience was repeated until each family member had a turn. Dinner ended only after we had a clear understanding of at least half a dozen such facts.
As children, we thought very little about these educational wonders. Our family, however, was growing together, sharing experiences and participating in one another’s education. And by looking at us, listening to us, respecting our input, affirming our value, giving us a sense of dignity, Papa was unquestionably our most influential teacher.
Later during my training as a future teacher, I studied with some of the most famous educators. They were imparting what Papa had known all along—the value of continual learning. His technique has served me well all my life. Not a single day has been wasted, though I can never tell when knowing the population of Nepal might prove useful.
1.What do we know from the first paragraph?
A. The author’s father was born in a worker’s family.
B. Those born stupid could not change their life.
C. The town elders wanted to learn about the world.
D. The poor could hardly afford school education.
2.The underlined word “it” in the second paragraph refers to “________”.
A. one new thing B. a request
C. the news D. some comment
3.It can be learned from the passage that the author________.
A. enjoyed talking about news
B. knew very well about Nepal
C. felt regret about those wasted days
D. appreciated his father’s educational technique
4.What is the greatest value of “dinner time” to the author?
A. Continual learning. B. Showing talents.
C. Family get-together. D. Winning Papa’s approval.
5.The author’s father can be best described as ________.
A. an educator expert at training future teachers
B. a parent insistent on his children’s education
C. a participant willing to share his knowledge
D. a teacher strict about everything his students did
