readingWe are in great danger!!!!earthquaketornadohurricaneeruptionflooddroughtvolcanoNatural disasters! What does an earthquake cause?ThinkingRoads get huge cracks.Steam bursts from holes or wells in the ground. Water pipes are destroyed.Houses fall down.
Brick buildings are destroyed.Dams and bridges fall down.
Hard hills of rock become rivers of dirt .Railway tracks are now useless pieces of steel.上图：四川绵竹县汉旺镇中学内，一位被埋在废墟中的女学生伸出一只求援的手不停地呼唤着“救救我”。孩子，别放弃希望，孩子，别哭！我们一定要把所有的障碍移开，让你重新看见蓝色的天空！在这苦难的一刻，所有的人都在伸出救助之手。 上图：四川省北川县北川中学，一名被压在瓦砾堆中的学生在接受救治。四川汶川地震发生后，北川县北川中学六至七层高的主教学楼塌陷，当时正值上课时间，21个教室里师生约1000人，除个别逃生以外，大部分被掩埋在瓦砾堆中。目前，大批武警官兵以及当地群众正在加紧救援。1000人啊！用什么能换回他们的生命！今后，应该规定，任何地方政府的办公楼，不得高于学校的标准！除了把最好、最安全的建筑给孩子们，还能用什么来补偿和赎罪！ 上图：救护人员在汉旺镇武都小学废墟上抢救幸存的小学生。在手拉着手的那一刻，孩子，你还会无助的哭泣吗？ 满身鲜血，但挡不住医护人员的真挚救护之心。后面的大哥，一定要抱好照顾好这位兄弟啊，你们痛苦就是我们的痛苦，党和政府没有忘记你们！只要有人在，我们还会重建家园的。
两个刚被救出的孩子，一个眼神很迷茫，似乎对地震还心有余悸；另一个好象已经进入了梦乡，也好象是受伤昏了过去。他们的父母呢？是不是还没有音信？地震对孩子们的心灵创伤尤大，谁来抚平？让他们有吃的，有喝的，把他们首先安顿好吧！一列摆放着的地震死难者遗体。大灾夺去了你们的生命，默哀！向你们的人送去深深的慰问和关切。
