开场白：Morning, everyone. Today I will share something about the environment with you. 1、Look at this picture. Does it remind you of anything? You see that river, gently flowing by; you notice the leaves, rusting with the wind; you hear the birds; you hear the frogs; in the distance, you hear a cow, you feel the grass, the mud gives a little bit on the river bank. It‘s quiet, it‘s peaceful. And all of a sudden, it’s a great shift inside you, and it’s like taking a deep breath and going, (深吸一口气)oh, yeah, I almost forgot about this. 2、This is a picture of the earth from space that any of us ever saw; it was taken on Christmas Eve, 1968, during the Apollo8 mission. We can see the earth within relatively comfortable boundaries. But we are filling up that thin shell of atmosphere with pollution. 3、This is the central park of Bit. I took it by myself on November, 1, 2013. On the picture, we see the whole park is covered with heavily thick smog. It was right on that evening, I had been playing the badminton outside with my friends for three solid hours. Thank god, I’m still alive. Do you feel a little frustrated just the same as me? Yes, we are always missing something only when we do not own it anymore. 4、It comes to me another well-known wisdom that what gets us into trouble is not what we don’t know; it’s what we know for sure that just ain’t so. ----Mark Twain This is actually an important point believe it or not, because there is an assumption that a lot of people have in their mind right now about the air pollution. They just think so, the assumption sounds like this, the earth is so big, we can’t possibly have any lasting harmful impact on the earth environment. Maybe that was true at one time, but it’s not anymore. And one of the reasons it is not true anymore is that the most vulnerable part of the earth ecological system is the atmosphere. Vulnerable, because it’s so thin. That is to say, anything what we had done can truly make a big difference to the environment. This is meant to be the end but we won’t end it here. 5、It’s so lucky for me that I toke this picture at the right same spot after I finished the preparation for today’s presentation. You see the blue sky; and the central park is filled up with warm sunshine and fresh air. Sometimes you feel some soft wind from nowhere. （放出第二张图片）Is it not beautiful? 结束语：thank you for listening. 本文来源：https://www.wddqw.com/doc/57a5a9465acfa1c7ab00cc20.html
