14、everybody should remember:practiceNow you are a reporter from the 21st Century,when you are making a social survey in your home town,you see some factories in your home town are seriously polluting the air and the water.The environment is not well protected.You are going to Interview a government of

15、ficial and write a report about what you see.You are supposed to tell the Importance of stopping the pollution and Protecting the environment.Now do the interview first in pairs and then make an oral report according to the following pictures.诗歌是一种忧郁的媒体，而诗人的使命是孤独的。垂下的头颅只是为了让思想扬起，你若有一个不屈的灵魂，脚下就会有一片坚实

16、的土地。只要春天还在我就不会悲哀纵使黑夜吞噬了一切太阳还可以重新回来只要生命还在我就不会悲哀纵使陷身茫茫沙漠还有希望的绿洲存在只要明天还在我就不会悲哀冬雪终会悄悄融化春雷定将滚滚而来 我和这个世界不熟。这并非是我安静的原因。我依旧有很多问题，问南方，问故里，问希望，问距离。我和这个世界不熟。这并非是我绝望的原因。我依旧有很多热情，给分开，给死亡，给昨天，给安寂。我和这个世界不熟。这并非是我虚假的原因。我依旧有很多真诚，离不开，放不下，活下去，爱得起。我和这个世界不熟。这并非是我孤寂的原因。我依旧有很多诉求，需慰藉，待分享，惹心烦，告诉你。我和这个世界不熟。这并非是我冷漠的原因。我依旧有很多动情

17、，为时间，为白为天黑，畏天命。那时我们有梦，一切都是命运，一切都是烟云一切都是没有结局的开始，一切都是稍纵即逝的追寻，一切欢乐都没有微笑，一切苦难都没有泪痕，一切语言都是重复，一切交往都是初逢，一切爱情都在心里，一切往事都在梦中，一切希望都带着注释，一切信仰都带着呻吟，一切爆发都有片刻的宁静，一切死亡都有冗长的回声。走吧，落叶吹进深谷，歌声却没有归宿。走吧，冰上的月光，已从河面上溢出。走吧，眼睛望着同一片天空，心敲击着暮色的鼓。走吧，我们没有失去记忆，我们去寻找生命的湖。走吧，路呵路，飘满了红罂粟。我不相信，生活是沼泽，我不相信，生命旅途不能一路高歌；我不相信，成长是懦弱，我不相信，双手握不住

18、执着的绳索。人生一世，草木一秋，我们就跟大树上的叶子一样，早晚会枯黄陨落。树叶虽小但见证了春秋，既目睹了繁花似锦，也目睹了大树凋零。我们都是很相似的树叶，因为人生就是这样，生老病死是谁都要经过的。如果你是条船，漂泊就是你的命运，可别靠岸。谁校对时间 谁就会突然老去 虽生犹死的寂寞让生命都凋零了人总要慢慢成熟，将这个浮华的世界看得更清楚，看穿伪装的真实，看清隐匿的虚假，很多原本相信的事便不再相信。但是，要相信，这个世界里美好总要多过阴暗，欢乐总要多过苦难，还有很多事，值得你一如既往的相信。人生不能像做菜，把所有的料都准备好了才下锅 卑鄙是卑鄙者的通行证高尚是高尚者的墓志铭 早上，灿亮的阳光扑进来

19、，他还睡着。我打开窗帘，看窗外那一片平凡而现实的风景。心想，在平凡和现实里，也必有巨大的美的可能吧。那时我们还年轻。穿过残垣断壁苍松古柏，我们来到山崖上。沐浴着夕阳，心静如水，我们向云雾飘荡的远方眺望。其实啥也看不到，生活的悲欢离合远在地平线以外，而眺望是一种青春的姿态。才子当然心里冰雪般的透彻：有些事，只能一个人做。有些关，只能一个人过。有些路啊，只能一个人走。不必向我诉说春天我的心里并没有秋寒不必向我解释色彩我的眼里自有一片湛我叹世事多变幻世事望我却依然 我和这个世界不熟。这并非是我逃避的原因。我依旧有很多憧憬，对梦想，对记忆，对失败，对希冀。我和这个世界不熟。这并非是我卑微的原因。我依旧

20、有很多勇敢，不信输，不信神，不信天，不信地。我和这个世界不熟。这并非是我失落的原因。我依旧有很多高昂，有存在，有价值，有独特，有意义。说实话离开故乡久了，家的概念变得混乱。有时我在他乡的天空下开车，会突然感到纳闷：我在哪儿？这就是我家吗？我家，在不同的路标之间。这世界上唯一扛的住岁月摧残的就是才华。1、垂下的头颅只是为了让思想扬起，你若有一个不屈的灵魂，脚下就会有一片坚实的土地。曾几何时，我们做了世上那最柔情的人，为一朵花低眉，为一朵云驻足，为一滴雨感动长的是磨难，短的是人生 生命之所以有意义是因为它会停止。生命可以随心所欲，但不能随波逐流。如果出现了绝壁，那么就越过它，就能把绝壁变成桥了一曲

21、终了，繁花散尽，伊人已逝，只余一声空叹。欲戴王冠，必承其重。有时候，同样的一件事情，我们可以去安慰别人，却说服不了自己。行到水穷处，坐看云起时。所谓的王，乃最贪婪，最豪爽，最易怒之人。且清且浊，追求极致人生。为臣者，因之而仰慕，追随其左右。因此，臣民才会有称王之志，追寻自己的理想。这个世界其实从不曾有一个人能取代另一个人的位置，所谓的取代，只是以前的那个人被遗忘面对大河我无限惭愧我年华虚度 空有一身疲倦和所有以梦为马的诗人一样岁月易逝 一滴不剩你穷，是因为你没有野心 见了他，她变得很低很低，低到尘埃里。但她心里是欢喜的，从尘埃里开出花来。如果你是鱼 不要迷恋天空如果你是鸟 不要痴情海洋 世界上的事情，最忌讳的就是个十全十美，你看那天上的月亮，
