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.

A.Fatigue toxins could hardly be found in a laborer’s blood.
B.Albert Einstein didn’t feel worn after a day’s work.
C.The brain could work for many hours without fatigue.

   This is new to me and I don’t know what I will say really so I’m just giving it a try. I was always a runner and in pretty good shape for most of my life. Then I hit a bad patch and each day just couldn’t get myself out there to run. I put on weight, which just made me feel worse about myself.

I finally got the running back again after a few years but it was much harder than it used to be and I struggled to get through even the shortest, slowest jog.

I was out in a run the other day and I had almost convinced (说服) myself to give up when I heard someone say, “You can do it! It’s hard, but you can do it!” There was a lady walking the other way and had the biggest smile on her face.

Those words of encouragement at a time when I was ready to give up were like a perfect intervention (干预). I finished my run and now every time I feel like quitting I will hear her words in my head and they give me motivation (动力) and encouragement.

I’ve never seen her again so I’ve never been able to thank her and let her know the effect something as simple as a few words of encouragement from a stranger had and still has on me. It always encourages me in my life and has great influence on my life. I will never forget it and place it in my heart. I will tell it to others and make others believe encouragement is very important to us.

【小题1】What was the author like before putting on weight?
A.He was very tall.B.He was in good shape.
C.He was very thin.D.He was in poor health.
【小题2】What does the underlined sentence mean in the first paragraph?
A.The author had trouble in life.B.The author’s clothes were worn out.
C.The author was very lucky.D.The author was in good spirits.
【小题3】What made the author not give up running?
A.His own hard work.B.A strange lady’s encouraging words.
C.His friends’ encouragement.D.His parents’ encouragement.
【小题4】What’s the main idea of the passage?
A.An exciting experience.B.A story about losing weight.
C.Kind words from a stranger.D.The importance of determination.

   Before I studied psychology, I used to think that people would laugh when funny things occurred. While I was right about that, I discovered there are lots of other psychological factors that make people laugh other than the funny part of a joke. When someone laughs at a joke, there will usually be more than one reason that makes him laugh—and the more reasons there are, the more powerful the joke will be.

I was attending a stand­up comedy show in Egypt, and when the man started to make fun of pedestrians crossing streets, everyone laughed their heads off. The main reason why those people strongly laughed was that almost all of them felt angry towards pedestrians who crossed streets carelessly. The joke wasn't only funny, but it also made the audience feel that they were right about being angry at those pedestrians. That is, people were laughing both because of the funny joke and because of the happiness experienced as a result of the psychological support they got.
The better a joke makes a person feel, and the more it includes other psychological factors, the more the person will like it. For example, if you envy one of your friends, and someone tells a joke that is funny and, at the same time, makes your friend seem stupid, then you will probably laugh at it louder than if you weren't jealous of him.
In short, we don't laugh only when we hear something funny; we also laugh when we experience some kind of happiness that results from the other psychological factors involved in the joke. I strongly discourage you from making fun of anyone or belittling someone to make someone else laugh. All I want to explain is that if your joke supports a person's emotions, he will certainly like it a lot.
