Nowadays, too much carbon dioxide makes the earth warmer and warmer and causes terrible effect to human beings. To save our planet and ourselves, a new lifestyle called low-carbon life becomes popular. Low carbon means low energy and no waste. It is necessary for everybody to learn to live a low-carbon life.

  To live a low-carbon life, we’d better save energy as much as possible. Turn off the lights and TV whenever they are not needed. If possible, use cold water to wash clothes or dishes. Take a short shower and try to take a cold one when the weather gets warm. Don’t do the cooking with electricity.

  To live a low-carbon life, we should eat less meat. Everybody knows eating too much meat makes people fat and easy to have heart disease, but maybe you don’t know keeping animals for food produces even more carbon dioxide than all the cars in the world, and being a vegetarian (素食主义者) can help reduce one and a half tons of carbon dioxide a year. Maybe it is a little difficult, but it’s really necessary.

  To live a low-carbon life, we are supposed to do less shopping. When we go shopping, we may drive a car or take other transportations (交通工具). On one hand, these machines pollute the air and waste energy. On the other hand, most of us always buy some useless things because of some advertisements. It not only waste money but also causes trouble to the earth, because making everything will produce carbon dioxide more or less.

  There are many other ways to live a low-carbon life, such as recycling things, planting trees and reusing textbooks. If we can keep it a habit in our daily life, the earth will become a safer planet for us to live on.

Do you like traveling? How can you make your trip interesting? Here’s some advice.
Read!
Before you leave, you should find some information about the place, such as its geography, history and people. You can introduce that place better by reading.
Take photos!
If you want to take some photos, remember to choose the most special sights. Don’t choose the sight you can see in other places. For example, Qingdao and Ningbo are coastal cities, so don’t only take photos of the sea. You should take photos of something else, too.
Taste!
You’d better taste some specials(特产) in the area. Food in some places is very delicious. So why not taste it? Maybe you have just one chance to taste it in your life.
Write!
When you visit a place, you should take a pen and a notebook, so you can write down what you see and what you think during the trip.
