垃圾分类，人人有责
地球是人类美好的家园，在宇宙里是一个非常美的蓝星，可是在地球里却有很多臭水沟、黑色浓烟……这都是怎么一回事呢？其实大部分都是垃圾填埋法和垃圾焚烧法造成的，让我细细道出它们俩办法的特点吧！
垃圾填埋法：简单地说也就是把垃圾放进人类事先挖好的大坑里，在用泥土稍微盖上去。可这种办法根本没用，除了可以不在生活中看见垃圾。可是在垃圾上面的土壤是寸草不生，不能在房子，也就是说这里是一个弹丸之地。经过人类多年来的改进，将衬垫隔离了土壤与地下水，将臭气从排气管排到高空，下雨造成的污水不会外泄，可这里还是不能造房子，所以这个办法怎么说都是不好的。
垃圾焚烧法：这种办法可以快速将垃圾“消失”，缺点有费电、有遗留物、黑色费烟……可这个方法受到了大多数政府的一致肯定，因为填埋法又破地又破财而且没什么用。垃圾分类主要用于垃圾焚烧法，第一步将可回收垃圾排去，剩下别的垃圾；第二步是将有害垃圾与其他垃圾这些干垃圾用普通火烧掉；第三步将厨余垃圾用电烧去。这样可以有效减少费电情况。
虽然垃圾分类很重要，但是减少垃圾“生产”更重要，所以人人都要担当起这个责任。
新材料作文分类【二】
材料在我们生活中无处不见。随着社会的发展，人们生活水平的提高，新材料不断涌现。但这些新材料大多不符合环保要求。建筑材料、特别是装饰、装修材料，气味剌鼻难闻，这些材料的放射性更是危害人们健康。
我要研究新材料的念头，还来自以下两个原因：寒假期间，我在新都奶奶家，看见一位漂亮的表姐，她因为头部受伤手术伤癒后，留下一条撤线的刀痕，lo厘长的刀疤像小小的蜈蚣虫，爬在表姐漂亮的脸蛋上，怪难看的！
又一次，我和爷爷到骨科医院去探望病人，他的腿部骨折已经癒合，但还要痛苦地再次手术，取钢板。而同病室的一个股骨头坏死的患者更是悲惨，医生要手术给他换人工股骨头，五至十年后，还要再手术再换。痛苦将没完没了地伴随他。
假如我是“新材料”科学研究员，我必将研究出安全、环保的建筑、装饰装修材料，给人们一个安全、舒适的\'居所。
假如我是“新材料”科学研究员，我必将研究出新型的医药用材料。使手术病人不再用线缝合伤口，而是用一种粘合膏，病人可以不留刀痕，保持肌肤完美。使骨折病人病癒后不再取钢板；使股骨头患者只需换一次人工股骨头。
假如我是“新材料”科学研究员，我必将研究出
但是，这些“假如”毕竟是今天的遐想，明天在召唤着我。为了实现自己美好的理想，我要努力地去追求，去奋斗。
