Most people around the world are right-handed. This also seems to be true in history. In 1799, scientists studied works of art made at different times from 1,500 B.C. to the 1950s. Most of the people shown in these works are right-handed, so the scientists guessed that right-handedness has always been common through history. Today, only about 10% to 15% of the world's population is left-handed.

Why are there more right-handed people than left-handed ones? Scientists now know that a person's two hands each have their own jobs. For most people, the left hand is used to find things or hold things. The right hand is used to work with things. This is because of the different work of the two sides of the brain. The right side of the brain, which makes a person's hands and eyes work together, controls the left hand. The left side of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show that more artists should be left-handed, and studies have found that left-handedness is twice as common among artists as among people in other jobs.

No one really knows what makes a person become right-handed instead of left-handed. Scientists have found that almost 40% of the people become left-handed because their main brain is damaged when they are born. However, this doesn't happen to everyone, so scientists guess there must be another reason why people become left-handed. One idea is that people usually get right-handed from their parents. If a person does not receive the gene (基因) for right-handedness, he / she may become either right-handed or left-handed according to the chance and the people they work or live with.

Though right-handedness is more common than left-handedness, people no longer think left-handed people are strange or unusual. A long time ago, left-handed children were made to use their right hands like other children, but today they don't have to.

  Why are so many people so afraid to fail ? Quite simply because no one tells us how to face the failure (失败）. In fact, failure can become experience that means growth. We forget that failure is part of the human condition and that every person has the right to fail.

Most parents work hard to prevent failure or protect their children. One way is to lower (降低)standards. Nearly 60% of the parents choose this way. When a child finishes making a table, the mother describes it as "perfect" even though it doesn't stand still. The other way is to blame (责怪）others. If John fails in science, his teacher is unfair or stupid.

There's a problem with the two days. It makes a child unprepared for the real life if they don't meet enough failure. The young need to learn that no one can be the best at everything, no one can win all the time. The young should be allowed to experience failure. 

Failure never gives people pleasure. It hurts both grown—ups and children. But it can be really good to your life when you learn to use it. 

The sky was pitch- black, the house was creaking (嘎吱作响), and I still had four hours until my parents got home. I locked myself in my parents' room and I turned up the TV so that I wouldn't hear the creaking house. 

Then the phone rang. I picked it up and said, "Hello… hello… ?" But there was no reply. I knew someone was on the other end. Finally, I hung up. A minute later, the phone rang again. Still no one said a word. I became more frightened (害怕的) as time passed. The phone rang again and again and again…

By the fifth time, I refused to pick up the phone, but the ringing continued. To get my mind off this strange caller, I called my friend. She told me not to worry and to turn the phone off. As we talked, I heard a car stopped in front of my house. When I looked out of the window, I saw an unfamiliar(不熟悉的) car. 

Thirty minutes passed and the car was still there. It drove up and down the driveway as if knowing I was watching.  ▲ , but I refused. 

Soon the phone calls started again. I heard noises in the background, but I couldn't tell what they were. I really didn't want that person to get out of the car and start towards the house. If he or she did, I didn't know what I should do. None of the doors to the house was locked, and I would have no way of protecting myself. The only thing I could do was to hide, which wasn't a very good plan. 

At this moment I was considering calling the policemen, but my friend offered to drive by. "Maybe if they see me come, they will leave, " she suggested. 

By the time she arrived, the car had left. The phone rang again and I picked up, thinking it might be my friend. Someone on the other end said, "Bye- bye. "

When I think back to that night, I am no longer frightened — just curious (好 奇 的 ). Who could it have been? Even so, since then I have not stayed at home alone and I probably never will again. 

Hello, everyone. My name is John White. I'm a middle school student. I like soccer very much（非常）. I play soccer after school every day. My father likes it, too. He plays soccer very well. I like playing soccer with my father very much. We have five soccer balls. But my mother and my sister don't like soccer. So they don't play soccer. They only watch TV at home. They think watching TV is very interesting.
