Dear Jack,
I am writing to tell you something about the activity Clear Your Plate Campaign you referred to in your last letter.
Clear Your Plate Campaign is intended to reduce food waste and help students realize how important it is to save food. Before the campaign, many students, unaware of their wasting of food, bought much more than they could eat and even threw the leftovers without a second thought. But encouragingly, knowing the significance of saving food after the campaign, more and more students are beginning to buy a proper amount of food for their meals. Actually, all of them find this mere action not only save food but money as well. They believe this life style is also environmentally friendly.
Personally, it is of great benefit to join in the campaign and form a good habit of clearing the plate. And it is essential to start with ourselves and start from now. Don’t you think so?
I’m looking forward to having your opinions of the campaign.
Li Hua

我写信是想告诉你一些关于你上次在信中提到的活动的事情。
清除你的盘子运动的目的是减少食物浪费，并帮助学生认识到它是多么重要，节省粮食。在运动之前，许多学生，不知道他们浪费的食物，买了比他们能吃的更多，甚至扔下剩菜没有思想。但令人欣慰的是，知道节约粮食的重要性的运动后，越来越多的学生开始他们的饭买适量的食物。事实上，他们都发现这种单纯的行动不仅节约粮食，而且节约金钱。他们认为这种生活方式也是环保的。
就个人而言，加入竞选活动并养成清除盘子的好习惯是大有裨益的。我们必须从现在开始，从现在开始。你不这么认为吗?
我期待着有你的意见的运动。
李华
