初二上册语文作文范文八年级上册语文作文人教版八年级语文上册第一单元作文例文 珍惜和平 纵观世界风云,战争贯穿着人类的发展史,由古至今,大大小小的战争不计其数。据 ___统计,人类历史上真正没有战争的日子只有300多年,可见战争就是人类矛盾不可调和的产物。尤其是两次世界大战把多少人类积累的财富毁于一旦,无论战争是正义还是非正义的都在怕坏着人类的发展。 由大导演斯皮尔伯格拍摄的《兄弟连》真是的反映了战争和战争中的人,他把战争描写的很贴切,很写实。因为他是以一群二战老兵的眼睛去看战争,而不是像无聊的国产剧是一群文人想象的。二 战老兵经历了真正的战争,他们懂得珍惜生命,热爱和平。这样的人我们崇拜他,他在战争中为战友付出着,和平时期他们为人们讲述着战争的残酷性,他提醒人们不要忘记战争的危害。而美化战争的人,还有英雄主义的文人们,他们没有让人们看清战争,英雄不是写出来的,英雄就在我们的身边。所以要反思战争,珍爱和平。

每一次战争损失的物质财富不计其数,第二次世界大战中,我国的损失就有3500亿美元,伤亡军民达3000多万。整个二战中损失的财富用金条来计算,它可以绕地球三周多。然而在战争中失去的不仅仅是物质财富,精神财富也在不断的失去,遗迹的毁坏,文物的毁坏,亲人的丧失,战争对人们的摧残都是残酷的。 战争的本质就是矛盾的激化,战争是统治阶级们为了满足自己要求而进行的,战争是统治阶级们的另一种发财之道。 如何才能消灭战争呢?只有民主制度才可以消灭战争,所以我们要求民主,建立民主制度。发扬民主,弘扬民主,贯彻民主才是我们奋斗的目标。 我只有这个,希望能帮到你。 一直藏在我心中的秘密 没有秘密的世界是空虚、失落的。我们每个人心中都有秘密,而且秘密都不同,你想知道我的秘密吗?那就请你再往下看吧!
