二、建议信模板（Advice Letter）
Dear Editor,
I am a high school student and I am writing to offer some suggestions about how to make our city's public parks cleaner and more enjoyable.
First, I suggest placing more trash bins in busy areas. Many people want to keep the parks clean, but they can't find a bin when needed. Second, it would be helpful to organize volunteer clean-up days every month. This could encourage community spirit and environmental awareness. Finally, adding clear signs that remind people not to litter would also make a big difference.
I hope you will consider these ideas. Thank you for reading my letter.
Yours sincerely,
Wang Lei
尊敬的编辑：
我是一名高中生，写信是想就如何让我们的城市公园更干净、更宜人提出一些建议。
首先，我建议在人流密集区域增设更多垃圾桶。很多人愿意保持公园整洁，但需要时却找不到垃圾桶。其次，每月组织一次志愿者清洁日会很有帮助，这能增强社区意识和环保观念。最后，设置醒目的提示牌提醒人们不要乱扔垃圾也会起到很大作用。
希望您能考虑这些建议。感谢您阅读我的来信。
此致
敬礼！
