Welcome to our class!
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。
