Is there anything worse than that? You bravely raise your hand to answer a question, but your teacher just point out that you're wrong. What a shame! What could the teacher make you suffer (忍受) this?

    Relax. {#blank#}1{#/blank#}. Your teacher isn't calling you out to humiliate (使丢脸) you, but rather out of concern for you and your education.

    Having all your classmates come to know your weak points can be pretty hard, so how can you get past the shame and recognize class participation as a learning opportunity?

    Get out of your comfort zone. Terrill Schumaker, a teacher, explains that “the more you speak out, the more you learn how to grow and build confidence. {#blank#}2{#/blank#}”

Realize it's not a big deal. {#blank#}3{#/blank#}. People aren't going to care all that much. “If I'm wrong or make a stupid point, then people laugh at me, but life moves on” says Grade 12 Kristen Wesenberg. Besides, everybody makes mistakes, and you can't be perfect all the time.

    {#blank#}4{#/blank#}. Of course it takes courage (勇气), but as Wesenberg says, ―What's the point of living in fear?‖ You won't learn anything if you are not brave enough.

    Use the experience as a learning tool. Wesenberg advises asking teachers why you're wrong so they can explain and you can learn.{#blank#}5{#/blank#}. If you're wrong now, at least you won't be wrong in your next test!

A. Be brave in class

B. Trust your teacher instead

C. Use class time as a mini—test

D. And it's not the end of the world

E. Then you can live an exciting life

    Have you ever counted the number of digits (数字) in your mobile phone number? Your number has 11 digits. You may sometimes find it hard to remember your number. That's because China has the longest mobile phone numbers in the world. Why is that?

    The 11 digits can be divided into three parts. Each part has a different meaning. The first three numbers tell you which mobile phone service company it is. For example, 135 is for China Mobile Communications

    Corporation and 188 is for China Unicom. The fourth to the seventh digits tell you where the number is registered (注册). And the last four digits are random (随机的).

    The main reason for using 11 digits is that we have the largest population in the world. We once had 10 numbers. But as our population grew, there were not enough numbers for us to use. So we began to use 11 digits starting from 1999. Eleven digits can be used to make tens of billions of mobile phone numbers. That's enough for each person to have seven or eight phone numbers to use in China.

    And mobile phone numbers can be recycled. Usually, the service company will reuse a canceled number after three to six months. If you call a number that you haven't contacted for a long time, you may find that its owner has changed.

    Besides China, Britain and Japan also use 11-digit mobile phone numbers. But their numbers always start with 0. So they cannot create as many numbers as we can. Countries like the United States, Australia and India use phone numbers with 10 digits. Canada's mobile phone numbers are perhaps the shortest in the world: they use seven digits.

    Qinghai Lake is in the northeast of the Qinghai Tibet plateau(青藏高原). ⑴It's the highest inland (内陆的)salt lake in China. It's like a blue mirror shining between snowy mountains and grasslands.

    There are three small islands in the lake. They are the paradise(天堂)for birds. Every year, thousands of tourists come here to enjoy the beautiful scenery(风景).

    ⑵People are trying to protect the lake and the land which is around it. Blue sky, clear lakes green grasslands and snowy mountains are all our treasures. We must treat them as our eyes.

    Great weather! It was sunny yesterday. We arrived in Beijing at 9: 00 in the morning. {#blank#}1{#/blank#} We went to the hotel by taxi. After lunch and a short rest, we took a bus to the Summer Palace. {#blank#}2{#/blank#} While we were in a boat on Kunming Lake, we heard someone singing Beijing Opera on the bank. {#blank#}3{#/blank#} In the evening we walked to Tian'anmen Square because it was next to our hotel. We took some photos there. {#blank#}4{#/blank#} This morning when we walked to the Palace Museum, we passed by (路过) a square and saw some people flying kites. The kites were in different shapes (形状) {#blank#}5{#/blank#} They were really beautiful. I'll go to the aquarium (水族馆), and then Beihai Park. The day after tomorrow we'll visit the Great Wall. I hear it's very great and I think I will have great fun playing there.

    We live on the earth. We use the sea around us. What do we take from the ocean? And what do we give to it?

    We take fishes from the ocean—millions of kilograms of fish, every year, to feed millions of people. {#blank#}1{#/blank#}We take minerals (矿物) from the ocean. We can get salt by evaporating (蒸发) seawater. {#blank#}2{#/blank#}such as gold. {#blank#}3{#/blank#}Seaweed (海草) becomes food of many kinds—even candy and ice cream—as well as medicine. Believe it or not, fresh water is another gift from the sea. We can't drink ocean water. {#blank#}4{#/blank#}But ocean water becomes fresh water when the salts are removed. In the future, we will find ourselves depending more and more on fresh water from the sea.

    The sea gives us food, fertilizer, minerals, water and other gifts. What do we give the sea? We pollute the ocean all the time. {#blank#}5{#/blank#}Throwing waste into the ocean is killing off sea life. Yet as the world population grows, we may need the sea and its gifts more than ever.

    We are finally learning that if we destroy our sea, we might also destroy ourselves. Hopefully, it is not too late.
