当地震、火灾、沙尘暴、龙卷风等自然灾害发生时，人类才真正意识到，面对强大的自然威力，我们的生命是多么的脆弱。然而，自然灾害，真的只是“自然”灾害吗？ Although known as “natural disaster”， I more believe it is caused by long­term human impact.Events that harm plants and animals we collectively(共同地；全体地) called disasters.Throughout human history we can see that disasters are caused by two main reasons: natural variation and human impact.Scientists proved to us those natural disasters are rarely caused by pure natural factors, especially nowadays human activities are more frequent.Because humans have immense(极大的；巨大的) demands, the destruction they made increases the frequency and extent of natural disasters.Human beings actually play as boosters(支持者) in natural disasters.As a resident or Earth, we should take the responsibility to protect our mother nature.First, we need do a lot of publicity to raise people's awareness and understanding of environmental conservation.Second, we should stop wasting and littering to conserve natural resources.Third, we should conduct recycling, slow down deforestations(滥伐森林) and also improve treatment of white pollution, try not to use plastic products.Fourth, turn off your electricity when you are not using it.Recycling batteries after batteries are depleted.There are many ways we can do for our mother nature, sometimes we just need to change a little bit.The only thing we should always keep in mind is that the Earth is the only home we rely on; to protect the Earth and prevent natural disasters is for ourselves and for our future generations to benefit. 1．What is natural disaster according to the passage? 　Events_that_harm_plants_and_animals.　 2．What is to blame for the natural disaster? 　Natural_variation_and_human_impact.　 Section Ⅰ　Reading and Thinking & Learning About Language Ⅰ.重点单词 基础单词 1．　emission　 n．排放物；散发物；排放 2．　melt　 vi.&vt.(使)融化；熔化；软化 3．　starve　 vi.&vt.(使)挨饿；饿死 4．　ecology　 n．生态，生态学 5．　release　 vt.&n.排放；释放；发布 6．　footprint　 n．足迹；(某物所占的)空间量；面积 7．　seize　 v．抓住；夺取；控制 8．　reform　 vi.&vt.改革；(使)改正；改造 n．改革；变革
