Students, on the evening of March 28, we held a "earth hour" activities, it is the world wide fund for nature to address global climate change have put forward an initiative, hope to individuals, communities, businesses and government in March 28, 2015, manner of an hour to go to bed late, to show support for the effort to tackle climate change.

When the sandstorm attacked Beijing, when the news came in taihu lake, dianchi lake pollution, when the snow storms, drought, extreme weather has been raging, when accelerating global warming, the Antarctic glaciers melt sharply, dear friends, have you ever wondered, with their own meager strength for us to live in the earth? So I took an active part in the activities, as we live in a city to do some contribution within our capabilities. Actually, short dark we not do less than an hour, it can not only let us contribute to his honesty, but also for more green and bright tomorrow. Some people will ask: "is not an hour? Power have so big?" Yes, one hour is trivial, but, if you think, with more than 1000 cities and 1000 an hour to calculate, this how strong! Is the so-called unity is strength!

Of course, our environmental protection effort is not limited to at this hour, but in all the time. When I turn off the lights at the moment, I do not know to come from a sense of happiness, I felt I did a very wonderful things, thought of here I will be very happy.

The classmates, action quickly! Let us join hands together, together to protect our homes, let our home more beautiful tomorrow!

同学们，在三月二十八日晚，我们举行了“地球一小时”活动，它是世界自然基金会应对全球气候变化所提出的一项倡议，希望个人、社区、企业和政府在2015年3月28日晚20：30熄灯一小时，来表明应对气候变化行动的支持。

当沙尘暴袭击北京的时候，当太湖、滇池污染消息传来的时候，当雪灾、大旱极端天气频频肆虐的时候，当全球加速变暖、南极冰川急剧消融，亲爱的朋友们，你可曾想过，用自己的微薄之力为我们赖以生存的地球做点什么?所以我积极参加了这项活动，以此为我们生活的城市做一些力所能及的贡献。其实，一小时的短暂黑暗我们并不是做不到，它不仅能让我们为自己的诚实做出贡献，而且还能换取明天更多的绿色和光明。有些人会问：“不就是一小时吗?力量有那么大么?”没错，一个人的一小时是微不足道的，可是，如果你想想，用超过1000个城市10亿人的一小时来计算，这个力量有多么强大啊!正所谓团结就是力量!

当然，我们的环保努力并不限于在这一小时，而在于时时刻刻。当我在关灯的那一刹那，我身边不知从何而来的一股幸福感，我感到我做了一件非常了不起的事情，想到这里我就会很开心。

同学们，快快行动起来吧!让我们一起携起手，一起保护我们的家园，让我们的家明天更美好吧!
