塑料瓶回收流程

发布时间:2024-06-09 点击:45
剑桥雅思16 test 4 writing task 1也是一篇流程图类型的题目,相关的作文结构和要点在之前的文章中分享过,这里分析下塑料瓶回收、处理和利用的各个步骤。
这张流程图中塑料瓶的回收利用总共分为九个步骤,前面三个步骤是讲塑料瓶的回收,后面六个步骤是讲塑料瓶的处理和利用,因此在主体(main body)可以分为两个段落来写。当然,写一个段落是没问题的,但是分段写会显得更有条理,结构也更清晰。
步骤1:将废弃的塑料瓶放入垃圾箱内(put plastic bottles in a recycling/garbage bin);
步骤2:回收和运输(collection and delivery by truck);
步骤3:对塑料瓶进行分类挑选(sorting);
步骤4:将挑出来的塑料瓶压缩成块(compress the bottles into blocks);
步骤5:将塑料瓶碾碎并进行清洗(crush and clean the bottles);
步骤6:将碾碎的塑料瓶做成塑料小球(use the crushed bottles to produce plastic pellets);
步骤7:对塑料小球进行加热,生成原材料(heat the pallets to form raw materials);
步骤8和9:利用原材料生产各种产品(raw materials are made into different types of end products)。
下面是google上搜到的塑料瓶回收利用过程,与文中的步骤略有出入,供大家参考。
recycling takes many steps. first, the bottles have to be collected from homes, businesses, and other sites. then, every plastic bottle must be separated from metal, glass, and other things that people put into recycle bins.
the plastic bottles are also sorted by the type of plastic they're made from. then, the bottles are cleaned remove any food, liquid, or chemical residue.
塑料瓶的回收过程涉及的步骤包括:1.从各种途径收集塑料瓶;2.将塑料瓶与垃圾箱里的其他垃圾进行分离;3.根据塑料瓶的材质对其进行分类;4. 清洗塑料瓶。
next, all of the bottles are ground up and shredded into flakes. finally, they are melted down and formed into small pellets, each about the size of a grain of rice.
the pellets are bundled up and sold to companies that can be melt them and make them into many different products. just think of all of the plastic toys, tools, electronic gadgets, and other plastic things in your own home. many of these are made with recycled plastic.
接下来的步骤包括:5. 粉碎塑料瓶;6. 溶解并制成细小的颗粒;7.打包出售塑料颗粒给生产厂家,由这些工厂制造成不同的产品。
