读大海，读出了它气势磅礴的豪情。
读石灰，读出了它粉身碎骨不变色的清白。
2、幸福幸福是“临行密密缝，意恐迟迟归”的牵挂；幸福是“春种一粒粟，秋收千颗子”的收获. 幸福是“采菊东篱下，悠然见南山”的闲适；幸福是“奇闻共欣赏，疑义相与析”的愉悦。
幸福是“随风潜入夜，润物细无声”的奉献；幸福是“夜来风雨声，花落知多少”的恬淡。

3、大自然的语言丰富多彩：从秋叶的飘零中，我们读出了季节的变换；从归雁的行列中，我读出了集体的力量；从冰雪的消融中，我们读出了春天的脚步；从穿石的滴水中，我们读出了坚持的可贵；从蜂蜜的浓香中，我们读出了勤劳的甜美。
4、成功与失败种子，如果害怕埋没，那它永远不能发芽。
鲜花，如果害怕凋谢，那它永远不能开放。
矿石，如果害怕焚烧（熔炉），那它永远不能成钢（炼成金子）。
蜡烛，如果害怕熄灭（燃烧），那它永远不能发光。
航船，如果害怕风浪，那它永远不能到达彼岸。
5、墙角的花，当你孤芳自赏时，天地便小了。
井底的蛙，当你自我欢唱时，视野便窄了。
笼中的鸟，当你安于供养时，自由便没了。
山中的石！当你背靠群峰时，意志就坚了。
水中的萍！当你随波逐流后，根基就没了。
空中的鸟！当你展翅蓝天中，宇宙就大了。
空中的雁！当你离开队伍时，危险就大了。
地下的煤！你燃烧自己后，贡献就大了6、朋友是什么？朋友是快乐日子里的一把吉它，尽情地为你弹奏生活的愉悦；朋友是忧伤日子里的一股春风，轻轻地为你拂去心中的愁云。
