现在的空气污染太严重了,渐渐使人得了绝症。我们要积极行动起来,保护空气不被污染。现在,汽车每天都排出大量的尾气;用完的包装袋,到处乱扔,就连湖里都是;还有马路两旁的烧烤摊上排出的黑烟,这些都对人的身体有很大的害处,甚至能将人致死。有一次,我和姐姐去公园玩,看见那里的环境实在太差了。草坪上、湖里、椅子上都是垃圾,时此,哪怕一个人只捡起一样脏东西放进垃圾箱里,就可以减少环境污染。从这时起我就想出一个办法。就是发明一个红色警报器。为了减少污染,我还要把警报器改进一些,我叫它环境警报器。它的作用很大。烤肉用电烤,把它安在电烤 The current air pollution is so serious that people gradually get a terminal illness. We must take active action to protect the air from being polluted.

The harm can even kill people. Once, my sister and I went to the park and saw that the environment was really bad. There are rubbish on the lawn, in the lake, and on the chairs. At this time, even if a person picks up only dirtiest things and puts them in the trash, he can reduce environmental pollution. From then on I came up with a solution. It is the invention of a red alarm. In order to reduce pollution, I also need to improve the siren. I call it an environmental siren. Its role is very great. The barbecue is grilled and it is grilled
