环城河以前是清清的,周围有绿绿的树,青青的草,还有小鱼、小虾。现在呢?我来告诉你们:
河水变成了灰黑色;河面上有许多垃圾,臭臭的,经过那里都要捂着鼻子走;一条大大的,圆圆的水泥通现在还在不停的流着工厂排出的废水。鱼也没有了,其他小动物也不见了。
我看爸爸老照片的时候,看到清清的水,绿绿的树,青青的草,河岸边还有小花。我问爸爸这是哪里,爸爸说这就是以前的环城河。
环城河受到了污染,变成了臭水河。所以我们要保护环境,从小做起!
最近,我对我家居住的卫校小区的空气质量进行了调查。经过这次调查,我发现小区的空气遭到了严重的污染,主要污染源是:小区旁的餐馆排放出的油烟;过路的车辆排放出的废气;附近的梅峰寺后山有人在烧垃圾,烟雾弥漫。正是这些有害气体污染了原本清新的空气。这些被有害气体污染了的空气,会对人体健康产生不利的影响,还会对周围的花草树木的生长造成了极坏的影响。
保护环境,人人有则。为了防止家乡空气受到污染,我想我们大家可以做好多事,为防止家乡空气受到污染献自己的一份力量。第一,可以给小区旁的餐馆写一份建议书,建议餐馆把油烟经过处理再排放到空气中去。还要改进汽车发动机,减少废气的排放;第二,大家要爱护花草树木,因为花草树木是氧气制造厂,空气过滤器,可以有效净化空气;第三,我们要注意搞好环境卫生,不乱扔垃圾,不随地吐痰等。
啊!我们从小养成保护环境的好习惯,养成良好的文明卫生习惯。大家动员起来吧!让我们生活的环境更加美好!
Children's finally here, it is our holiday, but imagine the children also accompanied by together, everybody is more excited.
Children on this day, white clouds float over the blue sky, the children also have made a hot air balloon, they sit together on yourself a hot-air balloon, extremely happy! Balloon flying high, and finally flew to the sky, the children are in the sky holiday, the children sit on clouds, umpa jump, like a frisky little monkey.
Playing children, suddenly to rain cats and dogs, the children of the balloon has stalled, baiyun sister swept away by the wind, the children fell into despair. Is a time of crisis, a group of dragonflies sister and sister flew caught the children, and the safety of the children to the ground.
On the ground, only butterflies woven into a rainbow "lei", the children wear a wreath, some like a fairy, some like a warrior.
Play tired, the children fell asleep between full of fragrance of flowers.
Children's good play my imagination, to one day be able to live in such a children's day.
Sometimes I dream about life in the future. What will it be?
Perhaps some people will go to the moon for a holiday or even live on the moon,and some scientists will build cities under the sea to make people live there. We can have a medical examination or do some shopping without leaving our homes,which makes the life more convenient. Maybe we will also do some shopping and work at home.
And I'm sure there'll be more educational programmes on the radio or TV or by the Intemet or videophones,so perhaps some children won't need to go to school every day. They'll study at home.
In the future,all electric equipment at home is under the con-trol of computers. People can learn about the situation of the house by working on the computer at the office. No people like doing housework. Maybe each family will have a robot. Every day we can tell the robot what to do-shopping,housework and so on. believe the dream will come true some day.
我们生活在钢筋水泥的森林里,我们对生机勃勃的树木远离了。现在的交通工具、建筑物或复杂的机械都给空气带来极大的污染,它们虽然都给我们带来方便,但大家有没有想到,它们也会污染空气对人体有害的。
此时此刻某些科学家已经研制发明出许多可以净化空气的物品和机器,人们可以利用这些东西将空气中的有害物体吸走,然后将新鲜空气排出,让空气更加清新。可我们人类不能依赖这些工具,并不是有了这些工具就可以乱砍滥伐树木。因为每一棵树木都是对我们很重要的,没有大树保护土壤,泥土就会被河流冲走;没有大树美化环境,人们就生活在乌烟瘴气的地球里;没有大树维持生态环境,动物就会渐渐稀少……这样一来再多机器也没用。大家看,现在空气污染这么厉害,大家也听说过“空气污染,全球变暖”吧!如果空气污染得太厉害的话,地球就会逐渐暖和,那时南极和北极的冰川就会融化,我们的家园会被淹没,这样整个地球都是茫茫大海,我们就会像神话一样,乘坐着“诺亚方舟”在海上漂流。所以说净化空气对我们很重要,我们要多植树让空气更清新。
让我们共同去植树,保护美好的大自然,爱护一草一木,让沙漠中的绿洲增加,大家行动起来吧!
