Recently, the news reported that one special kind of rhino from Africa just passed away, which meant the disappearance of this lovely creature. What a great pity. The tragedy is caused by the damaged environment, while human being must be blamed for it, because we have done so many bad things to pollute the environment and make the nature lose its balance. In order to make up our faults and save our offspring, it is in need of protecting the environment. As the ordinary people, we can do the small things, such as do not throw away the rubbish and join some activities to bring the world green, like planting trees. Every small act can make a difference. Some day, when we live with the environment friendly, what we do is worth.
最近,据新闻报道有一个犀牛去世了,是来自非洲的特殊品种,这意味着这类可爱的动物从此消失了,真是令人惋惜。造成这样的悲剧是由于环境的破坏而引起的,人类必须受到谴责,因为我们做了那么多坏事去污染环境,使自然界失去了平衡。为了弥补我们的错误,拯救我们的后代,保护环境迫在眉睫。作为普通民众,我们能做一些小事情来保护环境,比如不乱扔垃圾、参加一些像植树这一的活动给世界带来绿色。每一个小小的举动都能起到作用。总有一天,当我们与环境友好相处时,我们所做的一切就值了。
Environmental problems are becoming more and more serious all over the world. For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. Trees on the hills have been cut down and waste water is being poured continuously into rivers.Furthermore, wherever we go today, we can find rubbish carelessly disposed. Pollution is, in fact, threatening our existence.
The earth is our home and we have the duty to take care of it for ourselves and for our later generations. Fortunately, more and more people have realized these problems. Measures have been taken to cope with these problems by the government. Laws have been passed to stop pollution. I hope the problem will be solved in the near future and our home will become better and better.
环境问题变得越来越严重的世界各地。例如,汽车污染的空气影响了人们的呼吸,工厂释放污染的气体,山上的树木被砍伐。在山上的树木被砍伐,污水不断被倒进河流。另外,无论我们走到今天,我们可以找到垃圾随意丢弃。事实上,污染是威胁我们的生存。
地球是我们的家园,我们有责任照顾它为我们自己和我们的后代。庆幸的是,越来越多的人已经意识到这些问题。已经采取了措施来应对这些问题的政府。法律已经通过停止污染。我希望这个问题在不远的将来能得到解决,我们的家园将会变得越来越好。
