"XX school student collective food poisoning", "XX place bleak look-out collapse", "XX place again there was a traffic accident"... Life, always hear or see some strange, let person sigh of accident, one after another tragedy always constantly in front of us.

　　 Danger is in our each person's side, sometimes is so near to us. "Lucky" I experienced this once. That, I come home from school, saw this scene: a child was playing in the road, no attention paid to the coming danger, a large truck coming toward her. Others shouted, looking back, the children's truck, immediately panic, his face pale, legs a soft, straight down to the ground, big trucks the emergency brake, but it was too late, the boy has been under pressure in the car. People suddenly gave a shout, some with burying his face in his hands, did not dare to look down, some by the sudden scene scared silly, just stand in situ. "Another child forever left the world", is really sad. However, when people return to absolute being, has found that children had miraculously stood up, not a little damage.

　　 Many risks ah, had a narrow escape. Thanks to the girl in the middle of front, thanks to the car's chassis is high, if a little partial, if the body again a little bit low, the consequence is unimaginable.

　　 Security, is inseparable from a topic, we will never pay attention to safety, is we all know the truth. But safety accidents happen every day, and constantly increasing, every day in the heartbreaking tragedy. Safety first, with safety, we floral life to blossom. With safety, we can happily spend the youth, life for everyone only once, lost, will not come back. Whenever we up and down the stairs, a little light, quiet a little. Whenever we cross the road, look around first, then walked briskly, whenever we school, want to go home as soon as possible, don't play on the side of the road.

　　 Life is great, but it is fragile. We should cherish life, safety first!

　　 “XX学校学生集体食物中毒”，“XX地方煤井塌陷”，“XX地方又发生了交通事故”……生活中，总会听到或看到这样一些令人惊心，让人叹息的事故发生，一个又一个地悲剧总会在我们面前不断地上演。

　　 危险就在我们每个人的身边，有时离我们是那么近。我“有幸”经历了这么一次。那次，我放学回家，看到了这样一幕：一个孩子正在马路中央玩耍，丝毫没有注意到即将到来的危险，一辆大卡车朝她驶来。旁人高喊一声，那个孩子回头一看，是卡车，顿时惊恐万分，脸色发白，腿一软，人直直地倒在地上，大卡车紧急刹车，可是，已经迟了，那个孩子已被压在车下。人群顿时发出一阵惊呼，有的用双手捂住脸，不敢往下看，有的被突如其来的场面吓傻了，呆呆地立在原地。“又一个孩子永远地离开了这个世界”，真是悲哀。可是，当人们回过神来后，却发现小孩奇迹般地站了起来，没有受到一点伤害。

　　 多险呀，真是死里逃生。幸亏了那女孩倒在了车前的正中间，幸亏了那车的底盘高，如果再偏一点，如果车身再低一点，那后果不堪设想。

　　 安全，是我们永远离不开的一个话题，注意安全，是我们每个人都懂的道理。但是安全事故还是每天都在发生，而且不断地增多，天天都在上演那令人心碎的悲剧。安全第一呀，有了安全，我们如花般的生命才能绽放。有了安全，我们才能开开心心地度过青春年华，生命对每个人来说只有一次，失去了，就永远回不来了。每当我们上下楼梯，轻一点儿，静一点儿。每当我们横穿马路，先左右看一下，再轻快地走过，每当我们放学时，要尽快回家，不要在路边玩耍。

　　 生命是伟大的，但又是脆弱的。我们要珍惜生命，安全第一!
