【答案】Dear fellow students，
This Saturday morning，our school will organize students to enter the community and carry out a promotional activity with the theme of "Low Carbon，Green World".So it is our responsibility to have a low-carbon lifestyle，which matters more and more in energy saving and environmental protection.
In the activity，some students will give speeches about how to live a low carbon life，while some students will teach the people the importance of low carbon life.There will also be teachers involved in the activity，who will put up some posters to raise people's awareness of environmental protection.Let's participate in it and contribute to the prosperity of our mother—the earth.
