茫茫宇宙中,银河系的边缘有一颗蔚蓝的行星,她叫地球,她是人类的家园,也是人类的母亲。地球妈妈是伟大的,无私的,她把所拥有的一切全都给了自己的儿女——人类。而人类呢?却处处破坏环境,地球妈妈也在渐渐地衰老。记得小时候,家乡有一条河,它是那样清澈见底,河边绿草如茵,有许许多多的小花。我经常和小伙伴采花、捉鱼、摸虾。这里成了我们的乐园。可过了几年后,河边的一切都消失,一座座工厂拔地而起,四处是震耳欲聋的噪声、刺鼻的气味、弥漫的烟雾,天空不再蓝了。 In the vast universe, there is a blue planet on the fringe of the Milky Way. She is called Earth. She is the homeland of mankind and her mother. Mother Earth is a great, selfless woman who has given everything she has to her children. While humans destroy the environment everywhere, Mother Earth is also gradually aging. I remember when I was young, there was a river in my hometown. It was so crystal clear that there were many grassy flowers on the river. I often spend flowers and small partners, catching fish, touch the shrimp. Here has become our paradise. But a few years later, everything along the river disappeared. A factory stood in the air with deafening noises, pungent smells, filled smog and no longer blue skies.
