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.

A farm is always a busy place. One of the busiest things is when the farmer is getting land ready to grow plants.
If the farmer is going to grow wheat, he has to turn the ground over first. The farmer drives up and down the paddock(草地) on tractor(拖拉机). When the ground is ready, the farmer sows the seeds. He does this with a machine that the tractor pulls along. Now, one farm and one machine can do as much a day as twenty men used to do without a machine. After the wheat has been sown, the farmer keeps a lookout(守望) for rain. Wheat needs rain and warm sunny days to make it grow. When the wheat has grown, it turns to a lovely golden colour.
When the wheat is fully grown, you can see the seeds on the wheat plants. These have to be out off and put in bags or big trucks to be taken to a factory where they are made into flour(面粉).
It’s a very busy time on farm when the wheat is being cut. Everyone helps so that all the wheat can be taken from the paddocks before the rain comes. If heavy rain falls, the farm must wait for the ground dry out before the machine can cut the wheat. Farmers always have a lot to do through the year.

Born as the only child in the family, I am the “king” of the family. My parents are both businessmen and they come home every two weeks. Because they don’t spend much time with me, they always feel guilty* and will buy me many expensive things and let me do whatever I want. My grandparents never let me do any chores because they want me to do my schoolwork.
?? I used to take everything for granted*. I never said “thank you” to people. As time went by, I found that my classmates didn’t like me and my best friends left me. one day, I asked Leo, who used to be one of my best friends. He said that I was selfish, rude* and bad-tempered*. “No one wants to make friends with a person who always receives but never gives anything!” he said. I was shocked* at his words. “Oh, no! Please don’t leave me. I need friends! I will be lonely and unhappy without friends!” I locked myself up in the room and cried. “I want my friends back. But how?”
?? Then I noticed that all the popular kids in the class friendly to others. They always smile and say “thank you” to others. They do whatever they can to help when others are in trouble. Other kids like them and always play with them. “I need to change! I will get my friends back,” I said to myself. From then on, I started to change myself. I learned to say “thank you” to others. I smiled and volunteered to help other kids. I tried to be as nice as I could. Gradually, I found that other kids liked to talk with me and they would ask me to play with them and even told me their secrets. My friends came back to me again.
?? Now I have more friends than I used to do and I am happier than I used to be.
