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.

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.

Some years ago, writing in my diary used to be a usual activity. I would return from school and spend the expected half hour recording the day’s events, feelings, and impressions in my little blue diary. I did not really need to express my emotions by way of words, but I gained a certain satisfaction from seeing my experiences forever recorded on paper. After all, isn’t accumulating memories a way of preserving the past?

When I was thirteen years old, I went on a long journey on foot in a great valley, well-equipped with pens, a diary, and a camera. During the trip, I was busy recording every incident, name and place I came across. I felt proud to be spending my time productively, dutifully preserving for future generations a detailed description of my travels. On my last night there, I wandered out of my tent, diary in hand. The sky was clear and lit by the glare of the moon, and the walls of the valley looked threatening behind their screen of shadows. I automatically took out my pen...

At that point, I understood that nothing I wrote could ever match or replace the few seconds I allowed myself to experience the dramatic beauty of the valley. All I remembered of the previous few days were the dull characterizations I had set down in my diary.

Now, I only write in my diary when I need to write down a special thought or feeling. I still love to record ideas and quotations that strike me in books, or observations that are particularly meaningful. I take pictures, but not very often—only of objects I find really beautiful. I’m no longer blindly satisfied with having something to remember when I grow old. I realize that life will simply pass me by if I stay behind the camera, busy preserving the present so as to live it in the future.

I don’t want to wake up one day and have nothing but a pile of pictures and notes. Maybe I won’t have as many exact representations of people and places; maybe I’ll forget certain facts, but at least the experiences will always remain inside me. I don’t live to make memories—I just live, and the memories form themselves.

When Frida Kahlo’s paintings were on show in London, a poet described her paintings as “a ribbon (丝带)around a bomb”. Such comments seem to suggest Kahlo had a big influence on the art world of her time. Sadly, she is actually a much bigger name today than she was during her time.

Born in 1907 in a village near Mexico City, Kahlo suffered from polio (小儿麻痹症)at the age of seven. Her spine (脊柱)became bent as she grew older. Then, in 1925, her back was broken in several places in a school-bus accident. Throughout the rest of her life, the artist had many operations, but nothing was able to cure the terrible pain in her back. However, the accident had an unexpected side effect. While lying in her bed recovering, Kahlo taught herself to paint.

In 1929, she got married to Diego Rivera, another famous Mexican artist. Rivera’s strong influence on Kahlo’s style can be seen in her early works, but her later works from the 1940s, known today as her best works, show less influence from her husband.

Unfortunately, her works did not attract much attention in the 1930s and 1940s, even in her home country. Her first one-woman show in Mexico was not held until 1953.For more than a decade after her death in 1954, Kahlo’s works remained largely unnoticed by the world, but in the 1970s her works began to gain international fame at last.
