◎短文写作
根据汉语提示并运用本单元的词汇和语法写一篇短文
事实上, 垃圾处理工作并没有做得很好,人们把所有垃圾都扔进同一个垃圾箱。之后,一些垃圾被深深地埋在土里,这反过来造成了环境危机。同时,焚烧垃圾不仅释放化学物质,还会造成空气污染。因此,在每一方面都应该采取强有力的措施去解决这个问题。
【答案】One possible version:
In reality, garbage disposal isn’t done very well. People throw all waste into the same dustbin. After that, some waste is buried deep down in the earth, which in turn causes environmental crisis. Meanwhile, some wastes are burnt, which not only releases harmful chemicals, but also causes air pollution. Thus, intense measures should be taken to tackle the problem in every aspect.
