Every morning my father buys a newspaper on his way to work. Every evening my mother looks through magazines at home. And every night, I look at the posters with photos of David Beckham and Yao Ming on my bedroom wall before I go to sleep. Can we imagine life without paper or print?

    Paper was first created about 2,000 years ago, and has been made from silk, cotton, bamboo, and, since the 19th century, from wood. People learned to write words on paper to make a book. But in those days, books could only be produced one at a time by hand.  As a result, they were expensive and rare. And because there weren't many books, few people learned to read.

    Then printing was invented in China. When printing was developed greatly at the beginning of the 11th century, books could be produced more quickly and cheaply. As a result, more people learned to read. After that, knowledge and ideas spread quickly.

    Today information can be received online, downloaded from the Internet rather than found in books, and information can be kept on CD-ROMs or machines such as MP3 players.

    Computers are already used in classrooms, and newspapers and magazines can already be read online. So will books be replaced by computers one day? No, I don't think the Yao Ming posters on my bedroom wall will ever be replaced by a two-metre-high computer!

    Developing healthy eating habits starts from childhood, therefore it is important for parents to teach and provide children with a healthy diet.

    DPHSS administrator of the Bureau of Nutrition Services, Charlie Morris said, "A healthy diet for a child always includes a lot of fruits and vegetables in the diet limiting the amount of simple sugars in the diet and high fat food and highly processed* food." This means staying away as much as possible from food such as chips, cookies, candies and sugary drinks, because all children need to have meals and the meals should be a well-balanced diet.

    Community nutritionist* Thelma Romoso said, "The fruit, the vegetable, the grain, the protein, and also the milk, the diary product are all necessary in the diet for a child. Among them, the fruit and the vegetable should come first. It's easy for a mother to go into the two plus three concept* of fruits and vegetables or five a day." This concept means that there are at least two servings* of fruits a day, three servings of vegetables a day which can be served for lunch and dinner.

    Morris also said that the child's hunger level influences how much is eaten and the parent controls what and when the meal is offered, saying, "Mom needs to make sure that the food offered is good food for the child to eat and she also needs to consider how active they are through the day. Snacks* are not a bad thing, so the mom should offer good kinds of snacks as well."

    When it comes to preparing your child's lunch and snacks for school, make sure to keep in mind that the food you provide should not only provide enough energy but also be healthy such as fresh fruits, and whole grain bread. But parents must be sure to remember that a good healthy diet must be balanced with physical activity, that is to say, it is important that children get outside and run around and play and get activity besides eating a good diet.

    How do animals communicate (交流) with each other? They have special "languages". In fact, they are using signals (信号). Different signals have different meanings.

    For example, when a bee (蜜蜂) finds food somewhere, it flies home quickly. It can't speak, but it can tell others by dancing. Other bees will know where and how far the food is.

    Some animals show their feelings by making sounds. For example, when a dog is angry, it barks (吠). At this time, you'd better stay away from it. Birds can make several sounds to show different meanings. Sometimes we humans show feelings by making sounds instead of by speaking. For example, when we feel painful (疼痛的), we cry "Oh!" or“Ouch!".

    We humans have languages and words. We can communicate face to face by speaking. We can write down what happened in order to remember clearly. We can also send (寄) messages to people far away. But animals can't.

Vision—phones(可视电话)

    Many inventions are very useful in our daily life. They have greatly changed our life. For example, radios, telephones and televisions are widely used in the world. When you turn on the radio, you can listen. But when you use the telephone, you can not only listen to others but also chat with them. However, you can't see anything at all. The television is much better than both of them. People can watch TV and listen to it, but they can't take part in what they see.

    Today, some people are using a type of telephone called the vision phone. With it two people can see each other when they are talking

    Vision-phones can be of great use when you have something to show the person when you are calling him or her. It may also have other uses in the future. Some day you may be able to call up a library and ask to read a book over your vision-phone. You may be able to do some shopping through it too. Perhaps in the future, the vision-phone will come into wide use in our everyday life.
