One day, an expert in time-management was speaking to a group of business students. To make the point 1 , he used an illustration.
As he stood in front of the group, he said, “Okay, time for a quiz.” He then pulled out a wide-mouth jar and set it on the table. Then he    2   placed about a dozen fist-sized rocks, one by one, into the jar.
When the jar was filled to the    3   and no more rocks would fit inside, he asked, “Is this jar    4 ?” Everyone in the class said, “Yes.”
“Really?” Then he    5  under the table and pulled out a bucket of gravel（沙砾，石子），dumped some in and   6  the jar, causing pieces of gravel to work themselves down into the space    7  the big rocks. Then he asked the group the same question. “Probably not.” One of them answered. “Good!” he replied.
He reached under the table and    8   a bucket of sand. He started dumping the sand in the jar and it went into all the    9   left between the rocks and the gravel.    10   he asked the question. “No!” the class shouted. “Good!” Then he grabbed a can of water and began to pour it in    11   the jar was filled to the brim.
Then the expert in time-management looked at the class and asked, “What is the    12  of this illustration?” It is such a seemingly easy question that one   13   student raised his hand and said, “It is, however full your schedule is, if you try really hard you can always   14   some more things in it.”
“No,” the speaker replied, “The truth it teaches us is that you will    15   get them in at all if you don’t put the big rocks in first.    16   the big rocks in your life are, do things that you love and    17  for yourself. In your schedule if you value the little stuff then you’ll fill your life with    18   things and you will never have the real quality time you need to spend on the big, important stuff. So, tonight, or in the morning, when you are   19   on this short story, ask yourself what are the ‘big rocks’ in your life? Then put those in your    20   first.”

Mere 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.

64. 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.

65. 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.

66. 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.

67. 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
