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.

A song called Lonely Warrior(孤勇者) has been very popular among primary school students. The song has had so many comments（评论）{#blank#}1{#/blank#} the Internet. The singer Eason said it was out of {#blank#}2{#/blank#} expectation that so many people were attracted by the song.

There are some {#blank#}3{#/blank#} for the success of the song. The first reason is that the lyrics（歌词） of the song can encourage people {#blank#}4{#/blank#} they feel down. If you listen to the song, you may be {#blank#}5{#/blank#} with energy to face all kinds of difficulties. Another reason is the beat of the song is {#blank#}6{#/blank#} strong that you may feel excited and sing to the beat.

What's more, the background to the song is a moving story. The song was {#blank#}7{#/blank#} by a brave girl called Tang Tian. She is quite young but has fought a terrible illness for {#blank#}8{#/blank#} than ten years bravely. She is talented enough to create many popular {#blank#}9{#/blank#}, especially Lonely Warrior.

She hoped that her idol Eason could sing the song. Luckily, her wish {#blank#}10{#/blank#} true. From her, we all believe it's so important to have dreams and try to realize them.

When you do not use your arms or legs for some time, they will become weak. When you start using then again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way.

When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong.

If a friend says that his arms and legs are weak, we know that it is his own fault(过错).But if he tells us that he has a poor memory, many of us think that his parents are to blame(负有责任) and few of us know that it is just his own fault. Have you ever found that some people can't read or write but they usually have better memories? This is because they cannot read or write but they have to remember things. They cannot write them down in a small notebook. They have to remember days, names, songs and stories, so their memory is being exercised the whole time.

So if you want to have a good memory, learn from the people: practise remembering things as much as possible.

Peppa is a little pig. Many people know her name because they can see her on TV. Peppa has a big family. Her three family photos are on her desk. In the first photo, you can see Peppa's father, mother and little brother George. What about the next photo? Peppa's grandparents are in it. Who are in the last photo? Her uncle's family. Uncle Pig, Aunt Pig, their daughter Choel and their son Alexander.

 Now, let's learn more about Peppa's family.

▲Peppa likes red. She has many friends. George likes blue. He has many blueT- shirts.

▲Daddy Pig is an engineer(工程师). His friends, Mr. Rabbit and Mrs. Cat, do the same job. He loves watching TV. He doesn't like doing sports. Mummy Pig likes orange. She is very nice.

▲Grandpa Pig grows (种植) vegetables. Granny Pig can make delicious chocolate cakes. They have a tree house. Peppa and George love playing in it.

A young boy had many bad habits. His father was so 1 . He asked an old teacher for help. The teacher took the boy for a walk in the woods. While walking, he suddenly stopped and told the boy to pull out a small plant. 

The boy held the plant and pulled it out 2 . The old man then asked him to pull out a little bigger one. The boy 3 hard and the plant came out, roots (根) and all. "Now pull that one out. said the old man, looking at a small tree. The boy had to use all his strength to pull the 4 out. "Now pull this one out." said the old man, 5 a big tree. The boy held the trunk (树干) and tried to pull it out. But it didn't move at all. "It's 6 " said the boy, out of breath. 

"So they 7 bad habits," said the teacher, "When they are small, it is easy 8 them out, but when they grow bigger, they cannot be pulled out." The old man's words made a great difference to the boy's life. 

What we can learn from the story is: Don't wait 9 bad habits to grow in you. 10 when you have control over them, or they will control you
