    Earth is our home. It has air that we can breathe(呼吸). It has water for us to drink. It has plants and animals that we can eat. Earth is not too hot or too cold for us. It has everything we need to live.

    We are on earth, but we call see things that are not on earth. Early in the morning, we can see the sun comes up. All day, the sun seems to move across the sky. Later in the day, we can see the sun goes down. But the sun is not really moving around us. We are the ones who are moving. Every morning, we turn towards the sun. Every night, we turn away from it. Every year, we go around it. Earth is our spaceship. All of us in the spaceship are riding around the sun.

    At night, we can often see the moon and stars. From earth stars look like little points of light because they are so far away. But stars are really big. A star is a great mass of burning gas. It gives off light and heat. Our sun is a star.

    There are eight planets moving around our sun. Earth is the third planet around the sun. Some of the planets have moons. A moon goes around a planet just as a planet goes around a star. Earth has only one moon. Some planets have more.

    Doctors say that Morgan is doing well. （4）{#blank#}4{#/blank#}. "I want to meet my hero after I get out of the hospital," laughs Morgan. "That little robot saved my life!"

    Almost all of us have unpleasant habits. We all want to get rid of(摆脱) them, but we don't know proper ways. Here's some advice.

    ●Write down all the reasons why you want to stop some behavior. Look at the reasons very often.

    ●It's clever to do something else when you want to stop your bad habits. If you get angry easily, for example, you can go out for a walk.

    ●Decide what you'll do to reward(奖励) yourself if you really get rid of your bad habits.

    ●If you get too heavy, keep junk food out of your house.

    ●Bad habits develop over years, so you can't get rid of them very soon. So you should be patient.

    ●Don't be afraid to ask others for support. You can talk to your friends, family or other people. When you talk to them, they might be able to provide some advice that you can't get from yourself.

    In English, people use many expressions(表达) with the word "dog". People in the west love their dogs and treat them well. Dogs without owners to care for them lead a very different kind of life: The expression' to lead a dog's life" means living an unhappy life.

    Some people say we live in a dog-eat-dog world. That means many people are competing the same things, like good jobs. They say if a person wants to be successful he has to work like a dog. This means they have to work very hard. Such hard work can make people dog-tired. And, this situation would be even worse if they became ill as a dog.

    Sometimes we should let a sleeping dog lie, which means we'd better not trouble a person who may cause problems. And if someone says you are a lucky dog, he is just saying you're very lucky.

    Still, people say every dog has its day. This means that every person enjoys a successful period during his or her life. To be successful, people Often have to learn new skills(技能) . Yet, some people say that it's always impossible to teach an old dog new skills. They believe that older people do not like to learn new things and will not change the way they do things.

    There are also some other dog expressions. The dog days of summer are the hottest of the year. A rain in summer may cool the weather. But we do not want to have a very heavy rain. In other words, we do not want it to rain cats and dogs.

    Parents with high expectations for their children are nothing new to Chinese kids. However, people often don't realize that children also have expectations for their parents. What expectations do Chinese children have for parent-child relationships?

    China Youth & Children Research Center did a survey on this topic in the United States, Japan, South Korea and China. The survey found that 83.8 percent of Chinese children want to be friends with their parents, the greatest amount among the four countries. This means that they want a more equal(平等的) relationship with their parents.

    According to China Youth Daily, traditional Chinese values (价值观) such as respecting one's elders and the concept of hierarchy (等级观念) are preventing parents from becoming friends with their children. Many Chinese parents criticize (批评) and push their children, as there is lots of competition in school. It requires efforts from both parents and children to create a friendship in family. As children, what can you do to create a pleasant atmosphere (氛围) at home and make friends with your parents? Read on to find out.
