Here is an astonishing and significant fact: Mental work alone can’t make us tire. 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(情绪的) 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 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?

According to the author, which of the following can make sitting workers tired?

What’s the author’s attitude towards the scientists’ idea?

We can infer from the passage that in order to stay energetic, sitting workers need to ___________.

My name is Clara.I still remember that chilly December day,sitting in science class.I’d finished a worksheet early and picked up a TIME for Kids magazine. A piece of news caught my eye:NASA was holding an essay contest to name its Mars rover(火星探测器).Before I even knew anything else about it,a single word flooded my 11-year-old mind,Curiosity.
I couldn’t want for the bell to ring so I could get started on my essay.That afternoon,I raced home,sat down at the computer,and typed until my fingers ached. “Curiosity is an everlasting flame that burns in everyone’s mind...”
Five months later, my mon received a phone call,and immediately, a wide smile spread across her face.
On August 5,2012,at 10:31 p.m,the rover named Curiosity touched down safely on the surface of Mars,and I was honored to have a front-row seat in NASA.
Curiosity is such an important part of who I am.I have always been fascinated by the stars,the planets,the sky and the universe. I remember as a little girl,my grandmother and I would sit together in the backyard for hours.She’d tell me stories and point out the stars,Grandma lived in China,thousands of miles away from my home in Kansas,but the stars kept us together even when we were apart.They were always there, yet there was so much I didn’t know about them.That’s what I love so much about space.
People often ask me why we go to faraway places like Mares.My answer is simple because we’re curious.We human beings do not just hole up in one place.We are constantly wondering and trying to find out what’s over the hill and beyond the horizon.
