As we know, all living things have to eat food. For a man, a tiger, a fish, a bird, or even a worm, food is necessary. Generally speaking, all living things are sure to die without food. In every part of the world, many different kinds of animals share living places and live in communities (群落) together. They are connected in a food chain (链).

 Within a food chain, some living things are producers and some are consumers (消费者). Plants are producers because they use sunlight, soil and other things to make their own food. Animals are consumers because they have to eat other animals or plants.

There are four different kinds of consumers in the animal kingdom. A carnivore is an animal that only eats other animals. An herbivore is an animal that only eats plants. An omnivore is an animal that eats both plants and animals. A scavenger is an animal that eats dead animals.

 Look at the picture. It is an example of a food chain. The food chain shows the order that animals eat each other in a community. In the picture, you can see what animal or plant is food for another animal. See? A leaf is food for a grasshopper, which then becomes food for a hungry mouse. The mouse is food for a snake. The snake is eaten by an eagle. In this way, all of these animals are connected.

Dear Sonia,

    I'm writing this letter in the classroom. It's snowing outside and I'm sitting by the window.

    Some of the boys are playing on the playground. They are throwing snowballs to each other. Some girls are building a snowman, and some are chasing each other around the tree in front of the classroom. They are leaving footprints everywhere. Our teacher is shouting something loudly to them. In the classroom, some girls are drawing pictures.

     What are you doing?

                                                                                                                                                                           Yours,

                                                                                                                                                                            Tina

    Your schooldays should be some of the best and happiest days of your life. How can you get the most from them, and be sure you do not waste (浪费) this great chance to learn?

    Be active (积极的) at school. Don't say things are difficult or boring. Take an interest in your school life and school subjects. Take part in lots of activities (活 动). Put up your hands quickly in class. Go around the school with a big smile. If you are not working, you are wasting your time at school. Teachers can not make everything enjoyable (令人愉快的).

    Keep fit. If you don't eat a good breakfast, you will be thinking about food in class.

    If you go to bed late and don't have enough sleep, you will be sleepy in class. Play enough sports every day in order to keep your body strong.

    Face the problem. Do not say you will do things tomorrow. If you get behind the class, it is very difficult to get back in front. You cannot finish the race if you rest all the time. Everyone fails (失败) some exams, loses some matches and has a bad day. Don't make small problems very big and important. Don't forget to ask for help if you cannot solve the problems. You are young, and no one thinks you must do everything quite well!

    Spend the weekends. Don't waste time lying in bed on Saturday or Sunday morning. Go and play sports, get together with friends in the park to relax, learn to play the piano, or help someone with problems. If you don't want to go out, there are also a lot of things to do. You may read a book, practice English or help your mum with housework.

    Follow our advice, and have a happy school life!

    As a teenager, you have many dreams. These dreams can be very big, such as winning the Nobel Prize, or they can be small. You may just want to become one of the ten best students in your class.

    Once you find a dream, what do you do with it? Do you ever try to make your dream true?

    Follow Your Heart written by Australian writer Andrews tells us that making our dreams come true is life's biggest challenge(挑战).

    In fact, everyone can make his dream come true. The first thing you must do is remember what your dream is.

    Don't let it leave your heart. Keep telling yourself what you want. Do this step by step and your dream will come true faster because a big dream is, in fact, many small dreams.

    You must also never give up your dream.

    There will be difficulties on the road to your dreams. But the biggest difficulty comes from yourself. You may think you're not very good at some school subjects, or it is impossible for you to become a writer. These kinds of thoughts stop you from getting your dream, the book says.

    You need to decide what is the most important. Studying instead of watching TV will lead to better exam results, while saving five yuan instead of buying an ice cream means you can buy a new book. As you get closer to your dream, it may change a little. This is good as you have the chance to learn more skills and find new interests.

    The aim of students who come to school is to study. But t0 study requires a right way, or you waste either the time or the money. The following are the ways of studying.

    The best time for reading is morning, because in the morning, the air is fresh and the mind is clear. For that reason, we can get good result.

    In studying we must have patience. If we have not known a text well, we must read it again. We should not read the next one until we have learned the first one.

    When we are studying, we must put our hearts into the book, or we can get nothing from the book while we are reading.

    We must always ask "whys". If it is not well understood, write it down and ask our teachers or our parents, or friends. In any possible way, we must know it completely and what we've learned can be used well and made better.

    Though there are many ways for studying, yet the above mentioned will be quite enough if we can keep them in heart and do so.

    Here are three stars' family photos.
