现在地球上的污染日益严重,就连我们的学校也逃不出它的“魔爪”。有时候,风一吹便会扬起许多灰尘,还混着点沙粒,想飞进同学们的眼睛里;更严重时,空气中还弥漫着一股难闻的味道。在教室里还好,要是走出教室一看,好几家工厂的烟囱正向蓝天喷出滚滚白烟。每次上学和放学路上,我们更是饱受煎熬。于是,一个念头在我脑海闪过,要是每个学生都有一只环保书包,那该多好!这个环保书包怎么设计呢?
Now the pollution on Earth is getting worse, and even our schools can not escape its “claws ”. Sometimes the wind blew up a lot of dust, mixed with sand and wanted to fly into the eyes of the students. In more serious cases, there was an unpleasant smell in the air. Fortunately in the classroom, if out of the classroom a look, several factories chimney is blowing white smoke to the blue sky. Every time we go to school and get out of school, we are suffering even more. So, a thought in my mind flashed, if every student has a green bag, then that’s good! How to design this green bag?
