解答 Dear editor，
   I'm glad to write to you to express my idea about the  activity Earth Hour．As we know，our environment is becoming worse and worse．So it's necessary to hold Earth Hour to call on people to protect our envirnoment．（活动目的介绍）
   However，as more and more people take part in Earth Hour，many problems appear．So many people suddenly turning off their lights may affect the normal operation of the grid．What's more，some people have to use candles，which leads to another form of pollution．（高分句型一）
   In my opinion，what we should do first is to recycle some wasted things．（高分句型二）Second，we should plant as many trees as possible．Finally，we'd better live a simple，healthy and sustainable life．（提出建议）
   I really hope our environment becomes better and better．
   Yours faithfully，
