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 (大脑). The right side of the brain, which makes a person's hands and eyes work together, controls(控制) 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 than 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(损害) when they are born. However, this doesn't happen to everyone, so scientists guess there must be another reason (原因) 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-or left-handed according to the chance (偶然性) 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.

It’s the end of class.When the bell rings, students of Luohu Foreign Languages School in Shenzhen quickly take out their telephones.They want to log on to their micro blogs (登录到他们的微博) to check the interesting things.They want to see what have happened in the last hour.

When I was growing up in America, I was ashamed of my mother’s Chinese English. Because of her English, she was often treated unfairly. People in department stores, at banks, and at restaurants did not take her seriously, pretended(假装) not to understand her, or even acted as if they did not hear her.
My mother has realized the disadvantages of her English as well. When I was fifteen, she used to have me call people on phone to pretend I was she. I was forced to ask for information or even to yell at people who had been rude to her. One time I had to call her stockbroker(股票经纪人). I said in a voice that was not very convincing, “This is Mrs. Tan.” And my mother was standing beside me, whispering loudly, “Why he doesn’t send me the check. It’s already two weeks late.”
And then, in perfect English I said: “I’m getting rather anxious .You agreed to send the check two weeks ago, but it hasn’t arrived.” Then she talked more loudly. “What does he want? I’ll come to New York and say it in front of his boss.” And so I turned to the stockbroker again, “I can’t accept any more excuses. If I don’t receive the check immediately, I have to speak to your manager when I am in New York next week.”
The next week we ended up in New York. While I was sitting there red-faced, my mother, the real Mrs. Tan, was shouting to his boss in her broken English. When I was a teenager, my mother’s broken English embarrassed (使困窘) me. But now, I see it differently. To me, my mother’s English is perfectly clear, perfectly natural. It is my mother tongue. Her language, as I hear it, is clear and direct. It was the language that helped me form the way I saw things, expressed ideas, and made sense of the world.
