The is kind of lazy.

This summer, we on our trip.

Do you like walking? Jenny likes walking very much. She likes walking because she thinks walking is good for her health. "My home is six kilometers from my school, I get up at 6:00every morning. Then l have a good breakfast. I think breakfast is very important to us. lf we don't eat breakfast in the morning. We can't do well in our studies. After breakfast, I walk to school. I can see many interesting things and people on my way to the school. I can also think about what to do or how to do things at school," says Jenny.

 My father buys a new car and he wants to take me to school every morning. But I think l need to exercise and I ask my father to exercise, too. Now he walks to work. After dinner, my father, my mother and I usually take a walk in the park near our house. I have a happy family. And we have a healthy life.

How do you go to school every day? Walk to school now. It's good exercise. It's also good for the environment(环境). Do you think so?

    Hi, boys and girls! Welcome to our museum. It's free. You don't have to pay any money. But we have some rules for you. Please remember them and do as I say.

Fourthly, the museum is not open after five o'clock in the afternoon. Please leave（离开） before five. Have a good time here! Thank you.

    Our earth is in trouble. (2) Our drinking water is becoming dirtier, and the air is not as clean as before. People and factories are polluting the air, rivers and lakes and seas. You may think that there is nothing you can do to help. That's not true. There are many things you can do to help the earth. Cars burn gasoline. This will produce a lot of CO₂ into the air. Some people believe that too much CO₂ is making the earth warmer than ever. They think CO₂ thins the clouds above us. The clouds keep us away from the strongest sunlight. So try to walk, ride a bike or take a bus. And if you drive a car, drive at a steady speed. This can save some gasoline. The biggest energy use at home is for keeping (1) ___________or____________. So turn the air conditioner off when you don't need to use it. Use lights that save energy. Use fewer things that cannot be used again. When you buy something, consider those made from things that can be used again first. A lot of water is needed for a shower. In one week a family uses as much water for showers as a person drinks in three years! Take shorter showers. This can cut the use of water.
