Everyone has got two personalities (性格)—the one that is shown to the world and the other that is secret and real. You don't show your secret personality when you're awake because you can control yourself, but when you're asleep, your sleeping position shows the real you. In a normal night, of course, you often change your sleeping positions. The important position that best shows your secret personality is the one that you go to sleep.

    If you go to sleep on your back, you're a very open person. You normally trust people and you are easily influenced by new ideas. You don't like to make people unhappy, so you never express your real feelings. You're quite shy and you aren't very confident.

    If you sleep on your stomach, you are a person who likes to keep secrets. You worry a lot and you're always easily becoming sad. You never want to change your ideas, but you are satisfied with your life the way it is. You usually live for today not for tomorrow.

    If you sleep on curled up (蜷缩) , you are probably a very nervous person. You have a low opinion of yourself and often protect yourself from being hurt, so you are very defensive. You're shy and you don't usually like meeting people. You like to be on your own.

    If you sleep on your side, you have usually got a well-balanced (平衡的) personality. You know your strengths and weaknesses. You're usually careful. You have a confident personality. You sometimes feel worried, but you don't often get unhappy. You always say what you think, even if it makes people angry.

    I am Tom. My mom told me my first and second words were "Mommy" and "Daddy". The next one was "No". I didn't want to eat vegetables. I didn't want to go to bed early. I didn't want to study in the school. Being the "baby" of the family (I have two sisters)，I said a lot of "No".

    When I became a middle school student, my father had a talk with me. He asked me to say "Yes" more than "No". "You can have a different life when you do that," he said.

    Then I began to say "Yes" more. When mom asked me to give her a cup of tea, I said "Yes". I saw a big smile on her face. When Dad asked me to buy some food for him，I said "Yes". When he said "thanks" to me, I felt excited and happy. When I met problems in study, I said "Yes, I can do it!" I began to study hard and got good grades.

    Saying "Yes" can bring good luck to me and make me happy. Let's say "Yes" to life. Say "Yes" when others ask for help. Say "Yes" to make this world be a good place.

    Jeff Black has only one leg. When he was 12 years old, he got cancer. The doctor had to cut off most of his right leg to save his life.

    Every day Jeff walks with all artificial(人造的) leg. With the help of the leg, he can ski, ride a bike and play tennis. He can even run.

    When he was 22 years old, Jeff ran across the United States. He ran 5,150 kilometers. That was about 9.6 kilometers each day. Jeff wore out 36 pairs of running shoes and five artificial legs.

    On his way, people in every city gave Jeff some money. The money was not for Jeff himself. It was for a project, which helps people with cancer. Jeff talked to people about cancer and his disability.

    Though Jeff is disabled, he can do lots of things like a healthy man. He has finished college and now he is studying to be a lawyer. He says, "I want people to know that I ran not only for the disabled but also for everybody. I hope my spirit can cheer others up."

    We know the mosquito very well. Mosquitoes fly everywhere. They can be found almost all over the world， and there are more than 2，500 kinds of them.

    No one likes the mosquito. But the mosquito may decide that she loves you. She？ Yes，she. It's true that male mosquito doesn't bite（咬） and only the female mosquito bites because she needs blood to lay eggs. She is always looking for things or people she wants to bite. If she likes what she finds， she bites. But if she doesn't like your blood，she will turn to someone else for more delicious blood. Next time a mosquito bites you，just remember you are chosen. You're different from the others！

    If the mosquito likes you，she lands on your body without letting you know. She bites you so quickly and quietly that you may not feel anything different. After she bites，you will have an itch（痒） on your body because she puts something from her mouth together with your blood. By the time the itching begins，and she has flown away.

    And then what happens？ Well，after her delicious dinner，the mosquito feels tired. She just wants to find a place to have a good rest. There，on a leaf or a wall， she begins to lay eggs，hundreds of eggs.

    Is there intelligent (有智力的) life on other planets? For years, scientists said "no" or "we don't know". But today this is changing. Seth Shostak and Alexandra Barnett are astronomers (天文学家). They believe intelligent life exists (存在) somewhere in the universe. They also think we will soon contact these beings (人；生物).

    Why do Shostak and Barnett think intelligent life exists on other planets? The first reason is time. Scientists believe the universe is about 12 billion years old. "This is long enough for other planets to have intelligent life," say Shostak and Barnett. The second reason is size—the universe is huge. "Tools like the Hubble Telescope (哈勃望远镜) have shown that there are at least 100 billion galaxies," says Shostak. "And our galaxy, the Milky Way, has at least 100 billion stars. Some planets going around these stars might be similar to Earth."

    In the past, it was hard to look for signs of intelligent life in the universe. But now, powerful telescopes (高倍望远镜) allow scientists to discover smaller planets. These planets might have intelligent life.

    Have beings from space already visited Earth? "Probably not," says Shostak. However, intelligent beings may contact us in other way, such as radio signals (信号). In fact, they may be trying to communicate with us now, but we don't have the right tools to receive their messages. However, this is changing. By 2025, we could make contact with other life forms in our universe and we might help each other.

    I'm going to have a great weekend. I'll go across Canada with my parents by car. We'll drive seven or eight hours a day.

    In Toronto, we'll stay in a big hotel. The food is very delicious. There's a big swimming pool and a lot of game rooms. I think I'll play there happily. But there will be lots of people in the hotel, so I think we'll sleep in one room. And it's expensive.

    Then we are going to stay in a small cabin(小木屋) in the mountains. I really love it. The cabin is clean and quiet. We'll have two rooms, so I can get up late in the morning. But we have to get up early because we want to go swimming. There is a beautiful lake near the cabin. We can go fishing and cook food outside.

    American people like to say "Thank you" when others help them or say something kind to them. People in many countries do so, too. It is a very good habit.

    You should say "Thank you" when someone passes you the salt on the table,  when someone walking ahead of you keeps the door open for you, when someone says you have done your work well, or you have bought a nice thing, or your city is very beautiful. "Thank you" is used not only between friends, but also between parents and children, brothers and sisters.

    "Excuse me" is another short sentence they use. When you hear someone say so behind you, you know that someone wants to walk past you without touching you. It's not polite to break others when they are talking. If you want to speak to one of them, say "Excuse me" first, and then begin talking. You should also do so when you begin to cough or make any noise before others.

    Let's learn to say "Thank you" and "Excuse me".

    Devike was walking home from school. Everything was bad at school. In the morning, she got to school late. In the math test, half her answers were not right and she forgot to do her English homework. The teacher wrote a message in her notebook for her parents to sign.

    She knew her parents would be angry with her. She also knew she had a lot of schoolwork to do. Just thinking about these, she was sad.

    After she got home, her mother gave her a hug(拥抱) and said, "How was your day, dear?" Her little brother Rohit came to her and said," Hi, sister! I miss you.

    Quickly Devika felt better. Of course, her mom would be angry with her poor grades. But she loves her and that is more important. And her little brother always thinks she is smart and beautiful.

    At that time, Devika felt lucky to have such a great family and she didn't worry about her poor grades because the family could comfort(安慰) her when she was sad.

    Indonesia is my mother's homeland and one of my favorite countries. Since I was young, I had learned a lot about the country and become interested in it. For a long time I had wanted to do something for the country and people there, and I thought volunteering（做志愿者） would be a good and fun way to do so.

    I received the greatest pleasure from being with the children.

    Teaching my first English class in Aceh was exciting, but I was rather nervous. As time went by, I learned how to be a better teacher. Teaching was actually the most enjoyable of my many responsibilities(责任).

    Many children were shy at first. But when they relaxed, they would start talking and telling you a lot of funny things. I believed we were helping them build up their confidence.

    For the children who are more in need. The Education Program（TEP） will collect donations(募捐) to help them.

    As a volunteer, I had to visit the TEP children at home once a month and help them write a thank-you letter to their sponsors. This was a way for the children to communicate with their sponsors. Sometimes the sponsors would write back to the children. Seeing the children's happy faces, I had a great sense of pleasure.

    Clay Warner is wearing his basketball clothes, waiting in the chair for his chance to play—but until last week, nobody asked him to play. Although the 18- year-old students does well in playing basketball, his coach wouldn't like to bring Clay into play. He is afraid that Clay would get hurt.

    This is because it's kind of difficult for Clay to see things—even when he wears glasses. His mother says that he was born with cerebral palsy(脑瘫). Although he tries his best to look at the basketball hoop by focusing on the right corner of his glasses, it is not easy for him to do it well.

    On the high school's Senior Night last week, Clay's coach finally called him to play during the final minute of the game. With the watchers already standing to give him a warm welcome, Clay got into position as the crowd cheered him up.

    "I want to get him in. It was Senior Night," the head coach told reporters. "If there is an opportunity for him, I wanted to take advantage of it. All the player were for it, too."

    Once the game was back in play, one of Clay's teammates passed him the ball. Though he had been practising shooting hoops since he was in the third grade, this was the first time he had ever taken a shot on his high school basketball team.

    As the watchers waited, Clay took the shot and dropped the ball clean through the net, hardly touching the rim(边框)—and the watchers shouted in wild cheers.

    "This whole gym was calling my name," Clay told the news reporters. "The whole crowd was jumping. They were going crazy. It was like I were a little kid again."
