For those of us who are studying at school, the time of exams is very stressful (紧张的) and difficult. Some people find exam times so bad that they become ill, because they are afraid of failing; they are afraid of letting their parents and family down. If exams are really making you ill or worried, don't hide your feelings. Talk to someone about it. Maybe you can speak to a friend, or someone in your family, or teachers at your place of study. If one person doesn't help you, ask someone else.

      How to get through exams? Here is some advice:

      Ask a teacher or tutor about how to review your lessons, and exam skills—how to work when you are in an exam. Take short rests during your time of work. If your mind is tired, it will not remember well. Plan your work: study at times when you know you will work at your best. Get enough sleep, and eat healthy food. You need exercise to work well. Walk, run, play sports — whatever you enjoy. Stop thinking about the future and failing.

If you feel ill, talk to someone about your worries. But don't be too relaxed! Some stress over exams makes you work hard for them.

If it upsets(使某人不安) you to talk to your friends about an exam when it is finished, don't do it! In fact, don't even think about the exam you have finished. What is done is done. You cannot change what you have written!

      To this advice, we could add: If you are studying in the evening, don't go straight to bed. Your mind will still be “going round and round”—thinking too much. Do something else, maybe walk or get exercise. Choose something that will relax you, and make you think of other things.

    Casey was painting the sets (粉刷布景) for the school play (戏剧). When she worked, the actors practiced on stage (舞台). A girl named Amelia played an important role in it. Now she was singing.

    {#blank#}1{#/blank#}She saw the actors practice again and again. She remembered the words to all the songs by heart.

    Casey's friend Kareem helped her paint. "You should try out for the next play," he said. "You're good."

    Casey said, " {#blank#}2{#/blank#}"

    The next day, Casey and Kareem finished painting the last part of the sets. They were cleaning up their brushes and paints.

    "It's too bad!" Ms. Brown came in and said. " {#blank#}3{#/blank#}She can't be in the play. What will we do?"

    Kareem and Casey heard this. "You know all the words to the songs. You can take over Amelia's part!" said Kareem

    "No, I can't," said Casey.

    "Sure you can. {#blank#}4{#/blank#} You must do it!" said Kareem.

    Casey really wanted to act on stage. She thought, " {#blank#}5{#/blank#}" Then she took a deep breath (深呼吸) and walked to Ms. Brown, "I know what we can do!"

    Emperor penguins are the largest penguins on Earth. Each adult is over a metre tall, and can weigh up to 40 kilograms.

    For many months each year, emperors live near the sea in large groups called colonies. However, in May, the weather gets colder and ice covers large areas of ocean. Each colony moves many kilometres from the water.

    Sharing the work

    There, each mother penguin lays just one egg. Then all the hungry mothers must walk back to the ocean to find food. The father penguins put their eggs on top of the feet, under a special piece of skin called the brood pouch. For two months, the father penguins keep the eggs safe and warm. Antarctica. Most animals leave for warmer places, but the father penguins stay. In this time, without food, a father penguin can lose almost half of his weight.

    New life

    Then the babies begin to hatch! The mother penguin returns just in time to see her baby come out of its egg. The chick is then moved to her bored pouch. This can be difficult. If the chick falls, it can freeze quickly, so the penguin parents must be very careful! Once this is done, the father penguin can go back to the ocean to find food.

    Growing up

    Over the next few months, penguin parents take turns to go to the ocean for food. They each make the trip several times, bringing back food for the chick. The chick grows quickly and is always hungry.

    Into the water

    By December, winter is ending. The chick is five months old and can live on its own. Soon it enters the water for the first time. It will swim and eat until next April, and then return here. After a few more years, it, too, will start its own family.
