　　Dear Jack,

　　Thank you for your letter asking about our discussion on low carbon lifestyle. Here is something about it.

　　We can do a lot in our daily life to achieve the goal of living low carbon life. First, we’d better turn off lights if possible and spend less time watching TV or surfing the Internet. Saving water also matters much. Besides, we should sort out the rubbish, hoping that we might recycle some, which will surely benefit us a great deal. In addition, we suggest using handkerchiefs instead of tissues so that we can prevent more trees from being cut down. More importantly, when we go out, walking, riding bikes or taking buses should be our first choice, which contributes to a cleaner world.（約120字）
