Dear Teens,

  ①Do you wonder why some kids can stay calm while others get nervous so easily? Why do some kids do everything very quickly while others are verysluggish? Why are some kids always happy while some feel upset all times?

  ②One of the answers to these questions is personality(个性). People were born with different personalities. A baby gets its blood type, genes(基因) and other physical things when it is still inside its mother. These factors(因素) make part of your personality. Besides, family life, school learning and life experiences can also decide what kind of person you are. You may not like your personality. Don’t worry. You can always try to change it and make yourself better.

   ③If you are a selfish person who always thinks of yourself, you can start this way. Try to give others a hand and ask for nothing in return. The happiness you get from giving instead of receiving will help you change your personality.

   ④If you are very shy and don’t know how to make friends, just tell yourself to smile at others and start talking to others with warm greetings. You are sure to have more friends than you used to do.

   ⑤If you are a sluggish person who always does things slowly, you’d better make a plan every day. When you finish something, draw a happy face. If not, draw a crying one. No one would like to see a crying face and you will have the desire to change it into a smiling one.

   ⑥All in all, don’t get too worried about your shortcomings(缺点). No one is perfect. That’s why many people are trying to change. Don’t give yourself a hard time about it all. It’s not easy to change the habits overnight. Remember “ Rome is not built in a day”. Keep working at it. One day you’ll see that you can turn over a new leaf and be a new person.

Long ago, there was a mother and a son living in a house. She worked hard every day,    but  they were always poor.

The story happened on a hot heavy rainy day. After class, I wanted to get some water from the water room. Oh! There were so many people! I had to wait in the rain. My hair didn't get wet because I wore a hat, but my clothes did.

   When at last it was my turn, I filled the bottle as quickly as possible. I began making my way back when I saw a boy coming towards me, who was holding two umbrellas in his hand. As he came nearer, I recognized that it was Tom.

   Tom had been my classmate for nearly three years, but we never shared more than ten sentences. He was always silent, but I liked talking. We were quite strange people and had nothing in common. He was a cold person and I even didn't want to see him.

   "Hey!" He said, "I saw you standing in the rain, so I brought you this umbrella. But it seems a little late, your clothes are already wet." On hearing this, I couldn't say a single word.

   "Don't just stand there. Let's go!" He said and held the umbrella for me. We walked towards the dormitory(宿舍) and this time we talked a lot.

   "I really want to make friends with you." he said, "You may think I am silent, but it is because I always can't find the right words to say."

   The rain finally stopped and we saw a rainbow in the blue sky, I said to myself, "I would never judge(判断) someone only by his appearance."

What picture do you have of the future? Will life in the future be better, worse or the same as now? What do you hope about the future?

People predict that life will probably be very different in 2050. First of all, it seems that there won’t be TV channels (频道). At that time, people will pick up a program from a “menu” and a computer will send the program to the TV set at once. By 2050, music, films, programs, newspapers and books will come to us by computers.

In that time, water will become one of our most serious problems. In many places, farmers are in great need of water to grow fruit and vegetables.

In transportation, cars will run on new, clean fuels and they will go very fast. There won’t be any accidents because of robots. We will see robots everywhere. And space planes will take people around the world in two hours.

By 2050, we will be able to help blind and deaf people see again and hear again. At that time, people’s life will become better and better.

There are many kinds of tigers all over the world, and the largest tiger is Northeast Tiger. Most Northeast Tigers live in the northeast of China, like Heilongjiang Province and Jilin Province. Because there are many forests and mountains, the tigers usually like living there. In the forests and mountains, there are fewer people getting out and coming in. So the tigers are very free. They can run after each other, catch and eat some small animals, like rabbits and deer.

 The Northeast Tiger are different from the ordinary tigers. For example, the Northeast Tigers can swim very well, but can’t climb the trees. The Northeast Tigers’ hearing is the best, and no matter how low the sound is they can hear it.

 As the number of the tigers becomes smaller and smaller, we should protect the tigers as well as we can from now on.

Imagine the situation. You are driving along a desert or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car breaks down. It is night and it is cold. You have no mobile phone. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is a device(装置) which uses satellites to find the user’s position. It can find your position to within 20 metres. A GPS cannot start your car, but at least you will know where you are.

   GPS, which means Global Positioning System, is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put in your pocket. It is sometimes put into a watch or a telephone. We also find GPS devices in cars, planes, or boats. Some of these devices have electronic maps, so you know where you are. For example, in a city they can tell you the name of the street .

There are three parts to the Global Positioning System. The first part is the receiver. You can hold it in your hand, or have it fixed into your car, plane, etc. The second part is a group of satellites orbiting the Earth. The receiver contacts at least four of the satellites and calculates(计算) its position. The third part of the system is a network of ground stations. They are all over the world. They control the satellites and make sure they are working well.

   Some people think that in the future the GPS will be as common as the mobile. They are becoming cheaper and more and more accurate(精确的). There are also new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost again.

Have you ever seen people building houses? To build a house, you need workers. They use their hands, tools (工具) and machines to put things together. In fact, building the ISS(国际太空站) is the same. The difference is that the workers are astronauts. They walk in space and use robots' arms and hands to do their work.

   In the space station, astronauts always feel easy, because the temperature there is always about 21℃. But outside the station, it can be too hot or cold for people, In the sunlight, it's about 120℃; in the shadow of the station, it's about -85℃. So when astronauts walk in space, they have to wear heavy clothes — spacesuits. These special clothes can make the astronauts feel as comfortable as in the space station.

  Spacesuits also keep astronauts safe from flying rubbish (垃圾) in space. Each time people go into space, they leave rubbish there. So astronauts should be careful because there's a lot of rubbish—some rubbish goes many times as fast as a plane!

   Space walking is not easy, and it can be dangerous. So getting ready for it takes a lot of time to learn. Astronauts will need to do 160 space walks to finish their work in the ISS. That will take about 1,900 man-hour of work.

You love reading, but you've read all your books four times, and are tired of reading the same ones. You're planning to go to the library, but don't know what kind of books to get. With the right knowledge, it's easy to choose a good book!

Answer these questions first. What authors do you like? Research books by the authors you've enjoyed, and you can get more of the same type of books. What are your interests? Type your hobbies into your library catalog search. By doing this, you will find books that you might like. Is there a type of book you would like to try? If there is, search the book and read the summary. This will help you decide if the book is right for you.

Search your house next.Often good books are quietly collecting dust in your own house.Maybe you forget about one, or someone who is living with you has a couple of good books. Also by searching your house, you can find some books that you can read, and they won't even cost you any money.

Then, ask someone to recommend a good book. You can ask your older brother or sister, your mom, your dad, your best friend, or even your English teacher. Local bookstores oft en have wonderful recommendations. And when they get to know you, it's even better! You should ask people who like the same type of books, so that you can get books that match your need.

 Join a book club, please. Being a book club member is often a way to experience new books with other members. Joining a book club or setting up a book club helps you know who else likes the same books as you, and you can read books that others have read and discuss them.

Finally, read the first part of each book. Of course, if you have many books, this can betime-consuming. Reading the first part of a book can help you know what books and types of books that you like, and you won't have a hard time looking for books again. CBD
