Now the human living environment is becoming worse and worse。 So a new lifestyle called low-carbon life is spreading to every part of our country。 As middle school students， how can we have a low-carbon life？

　　Firstly， we can go to school on foot or by bike。 Secondly， we shouldn’t waste water or electricity。 Do remember to turn off the lights when we leave the room and turn off the tap in time after using it。 Thirdly， we should use colth bags in our daily life instead of plastic ones。 Fourthly， we should also make full use of paper。 We’d better recycle some of our textbooks。 

　　It’s important for us to live a low-carbon life to protect the environment。

　　How to behave well？

　　As a student in Yibin， we should behave well。 

　　First， I think it’s very important to do everything on time and keep promises。 Never lie to others or say dirty words。 Next we should be polite to others and ready to help people in need。 Then we’d better not talk loudly in public。 Don’t throw litter or spit about。 And remember to obey traffic rules。

　　Finally， learn to work with others。 We need good team work in our life。
