【题目】Here is an astonishing and significant fact: Mental work alone cant 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 Englands 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.

【1】 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.

【2】 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.

【3】 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.

【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

Have you ever been sad because of failure? Please remember, for often, achieving what you set out do is not the most important thing.

A boy decided to dig a deep hole behind his house. As he was working, a couple of older boys stopped by to watch. “What are you doing? asked one of the visitors. “I want to dig a hole all the way through the earth!” the boy answered excitedly. The older boys began to laugh, telling him that digging a hole all the way through the earth was impossible. After a while, the boy picked up a jar. He showed it to the visitors. It was full of all kinds of stones and insects. Then he said calmly and confidently, “Maybe I can’t finish digging all the way through the earth, but look at what I’ve found during this period!”

The boy’s goal was far too difficult, but it did cause him to go on. And that is what a goal is for-to cause us to move in the direction we have chosen, in other words, to cause us to keep working!

Not every goal will be fully achieved. Not every job will end up with a success. Not every dream will come true. But when you fall short of your aim, maybe you can say, “Yes, but look at what I’ve found along the way! There are so many wonderful things having come into my life because I tried to do something!” It is in the digging that life is lived. It is the unepected joy on the journey that really makes sense.
