人类把许许多多的风景都污染了。比如:海水里、森林里、草坪里等等。
我想知道空气中粒子状污染物是怎么形成的:空气中的粒子状污染物数量大成分复杂,它本身可以是有毒物质或是其他污染的运栽体。其主要来源于煤及其他燃料的不完全燃烧而排出的煤烟。工业生产过程中产生的灰尘、建筑和交通扬尘、风的扬尘等,以及气态污染物物理化学反应形成的`盐类颗粒物。在空气污染检测中,粒子状污染物的检测项目主要为总悬浮颗粒物、自然降尘和飘尘。
我想对人类说:希望你们要爱抚花草树木,不要再污染环境了!
I like busy, busy city, I prefer quiet, leisurely countryside.
When the weather is fine, walk path in countryside, the distant mountains like the green barrier, isolates the hustle and bustle of the city. Roadside piece dignified standing forest of pine trees, like the army of the discipline in a head of inspection. In the sun, the flowers bloom smile, green leaves of green, bees are busy mining, butterfly dance. Kids of cattle lying on the grass on the side of the road to read with relish, not far from the tame cows eat grass in bend both ends.
Peasant madadayo smoke from kitchen chimneys, above the house the children in the bamboo forest is cut down a pieces of bamboo as a weapon, ready to back down the man smoking a cigarette in bamboo chair in front of the yard, quietly watching running around foraging in a crowd. "Eat", the mistress of a summons, everyone sitting around the hearth, watched stewed up with skin and preserved pig feet, red pepper Fried turnip, homemade sweet bean curd, cold fold son root.
The beautiful rural scenery, the quiet life of the country just like tao yuanming's shangri-la, deeply attracted me.
我喜欢热闹、忙碌的城市,更喜欢宁静、悠闲的乡村。
天晴的时候,走在乡村的小路上,远处的峰峦像绿色的屏障,将城市的喧嚣隔离开来。路旁成片的松林威严地挺立,像纪律严明的军队在接受首长的检阅。在阳光的照射下,花儿绽放笑脸,叶子绿得碧眼,蜜蜂忙着采密,蝴蝶翩翩起舞。放牛的娃儿躺在路边的草地上津津有味地看书,不远处两头温顺的牛儿在低头吃草。
农家上空炊烟袅袅,屋后竹林里的孩子们正砍下一截截竹子准备当武器,下地归来的男人叼着烟坐在院子前的竹椅上,静静地看着跑来跑去觅食的鸡群。“吃饭了”,女主人的一声召唤后,大家围坐在炉子边,有滋有味地吃起带皮炖腊猪脚、红辣椒炒大头菜、自制香豆腐、凉拌折儿根。
美丽的乡村景色、宁静的乡村生活就像陶渊明笔下的桃花源,深深地吸引着我。
