记得几年前,爸爸妈妈带我去看望外婆,外婆家门前有条小河,河水清凌凌的,闪着金光,缓缓地向前流着。河边,一群阿姨正欢笑着在洗衣服,一群孩子在河中游泳、嬉戏。我和妈妈挽起裤脚在河边捡鹅卵石,爸爸在旁边悠闲地垂钓。这安乐祥和的景象,现在我还记忆犹新。
然而,几年后的一天,当我再次看到那条河时,不禁吓了一跳。河水已经不清澈见底了,水是浑浊的,还夹杂着一些脏东西,光秃秃的河床上,水已快枯竭了,还散发着臭气。这些臭水是从哪里流出来的呢?我放眼望去,只见几家工厂正向天空喷射着烟雾,烟雾污染了白云,然后变成酸雨飘落下来,毒害大地;同时,工厂还不断地向河流排泄废水,将清清的河流变成了浑浊的毒水。煤是大自然几亿年蕴藏的太阳能,而在短短的几百年内得大量的开发和利用,大量的煤炭燃烧生成二氧化碳,造成了地球的温室效应。同时煤中数少量硫的燃烧生成二氧化硫气体,随雨水降到地面上,形成酸雨。酸雨毁坏了大量森林,成为生态系统的空中***手。
排水场的水还不断地向河里排放污水,就连河边的植物也死去了。这不就是垃圾场吗?原来干净的河水不再清洁,河水也不再流淌、空气不再清新。人们到底对这条相伴多年的老河抱着什么样的态度呢?是继续污染环境还是保护河流呢?是做破坏者还是做环保者呢?
由于水源的污染和地下水的超量开采,人类的淡水资源已经开始告急。由于森林的砍伐和过度开垦,放牧、水土流失和土地沙漠化问题日趋严重。由于地球的破坏,截至xx年已有2、3万种植物和1000多种脊椎动物绝灭,现在每小时就有1种生物从地球上消失。土地污染,人类乱砍树木,岩石下滑,洪水冲毁了房屋,淹没了庄稼;人们往河里乱丢垃圾,造成了水污染,到处可见随手扔掉的塑料口袋,形成白色污染。人们乱***动物,造成动物灭绝;人们乱摘花木,使我们失去了美丽。人类只有一个地球,我们生活在地球上,就要保护地球,保护我们的家园。
I have a great mother. She cares much about me in my life and study.
In the morning, she gets up early to make breakfast for me. When I was little, she prepared my schoolbag. But now, she tells me to do it by myself. Because she thinks I have been old enough to do it. Besides, she always checks my homework. When I finish my homework, she checks it and points out the mistakes. She is very careful and helps me a lot.
