在我小时的眼里,懂得主动把垃圾扔在垃圾桶里的,就已经是个好孩子。而老师每天教我们的种种道理中,就不乏把垃圾扔进垃圾桶里。
新加坡的法律就规定不许乱扔垃圾,否则就要受到惩罚,而我们国家,只是在道德舆论上有要求,却不是强制执行。现在,广州有多个地方实行试点垃圾分类,许多人都不看好,因为实施起来困难重重。
“垃圾按袋计量收费”和“垃圾不落地”模式在广州某些区实行起来了。不过,“厨余垃圾专袋投放”被认为是这三个模式中最有效实施,也最能有效达到垃圾减量的目的。其实我也很支持政府的做法,是为我们的环境为我们的子孙后代而努力。
在香港,有一个公益组织,买了一些设备,可以使餐余垃圾分解,成为肥料,可用于培养土壤的肥沃度,这样既有利于垃圾无害化处理,也有利于土壤变肥沃。
不过之前的土壤重金属问题也备受关注,这危机到我们的蔬果安全问题。人们总说,不要问我想吃什么,要问我可以吃什么。这便是中国如今食品方面问题的缩影。
所以说,在垃圾分类方面,我们不仅要分好其他垃圾、可回收垃圾和餐余垃圾,也要重视有害垃圾。
可是,现在有少数人们连什么垃圾属于哪一类都不知道,教人如何分类?所以说,想要做好垃圾分类的工作,应该一步一步地改进。要加大力度去宣传,来提高人们的环保意识。
当然,还有一个现在社会较为严峻的问题,那就是电池。一粒纽扣电池可污染60万升水,等于一个人一生的饮水量。一节电池烂在地里,能够使一平方米的土地失去利用价值,所以把一节节的废旧电池说成是“污染小炸弹”一点也不过分,重金属污染威胁着人类的\'健康,人类如果忽视对重金属污染的控制,最终将吞下自酿的苦果,因此,加强废旧电池的回收就日显重要了。
但是,用剩的废电池,我却不知应该交给谁,怎样去处理它。因此,我认为政府也应该在这方面出一份力了。
如果每个人分一下垃圾,或许,我们的家园就可以干净一分,这更是为我们的将来而着想。之所以我们要重视垃圾分类,是因为环境的保护很重要。
垃圾分类,简简单单的四个字。你,做到了吗?
①按时间先后和情节的变化发展分段
②按空间变换或场地转换分段
③按材料性质分段
④按作者思想感情变化分段
⑤按人物活动分段。
划分好段落后,概括段意,也可遵循以下方法:
①摘句法,直接摘引原句
②缩句法,有些段由一个长句组成,概括段意时,可将其压缩
③串联法,把层意合并归纳
④择要法,取主要层意为段意
⑤归纳法,在无法使用上述各法时,可把一段中的\'几层意思归结到一起,用自己的语言概括本段的段意。
以上方法,可以在实践中不断提高,段落大意归纳中涉及的缩句等方法需要懂句子结构知识,可以参看华语网(Thn21.com)相关文章。
但从前,有一只绵羊,它和其它绵羊不一样,别的绵羊每天忙里忙外地耕耘,而它呢,却独自一人种了一盆草,等待小草长大了,便当成食物吃掉。
这个故事呢,告诉我们的道理,真是“一份耕耘一份收获”。
大家应该猜得到结局,其它绵羊过上了幸福生活,有足够的粮食过冬,收获颇丰。而另一只绵羊却断了自己的粮食,只够它自己吃一顿,它只能饿死。
农民伯伯们锄禾日当午,汗滴禾下土,才会有我们如今社会上的美食。
大家想想看,如果这个世界上每一个人都学习那一只羊,我们还会存活至今吗?所以,我们也需要勤奋学习,这样才能有所收获。
这世间万物不都需要勤奋吗?就像那事业有成的人或明星都是靠着自己的努力,才会取得今天的成功。
“少壮不努力,老大徒伤悲”这些名人名言都是告诉我们,要做勤奋的`人,不要做懒惰的人,如果你今天选择勤劳,明天将会有所收获,走向成功,如果选择了懒惰,那等待你的只有失败。
这些事都像羊种草的故事一样,提醒我们“一份耕耘一份收获”。
nowadays, we can see some boys and girls who live in a small world of their own. they bury themselves among books and are proud of themselves. they think that it will make them lose their face if they do housework for they often think themselves very noble.
these young people are wrong. in my opinion every student should have a knowledge of housework. after all, they will have a family of their own, and they should do their part in keeping a good home. boys should also learn to do housework, for what will they do if they remain single? though not all boys remain single,yet they will be very helpful in the family if they know some housework. anyhow they will not lose anything, but, on the contrary, they will gain something useful.
for what i said above, we can find some eamples of our fellow-students studying abroad. all young men do housework as girls do. someone would argue that we can employ servants. this is true.however, what shall we do if the servant leaves us and all things are left to ourselves? we just cannot leave our clothes as they are and let worms and ants eat them up. and what can we do it we go and study in a foreign country where servants are out our means to employ? we must work for ourselves. why not start to learn to do housework now or else it will be too late? everyone should learn to do housework. what do you think about my idea, boys and girls?
