流程图

【题目解析】

该流程图展示的是家庭垃圾填埋装置的建造以及使用过程。图中分为建造(construction)，使用(use)和密封(closure)三个部分。从图中可知，填埋点需要先在自然岩层(natural rock)中挖坑，之后铺设粘土(clay layer)以及合成材料层(synthetic lining)，在底部有排水管(drainage pipes)以及排水箱(drainage tank).

使用时，卡车会将垃圾倾倒在填埋坑，液体垃圾会储存在排水箱里。垃圾装填完毕后，会使用粘土封顶，并留有一个管子用来排气。

【写作思路】

开头段：转述题目

主体段1：描述填埋装置的建造过程以及所用的材料

主体段2:描述填埋装置的使用以及密封

总结：填埋方法是一种较为简单的垃圾处理方式，并不需要过于复杂的步骤以及多种设备材料。

【参考范文】：

The design of a landfill for residential waste,including details about the construction and usage is illustrated in the diagram.

It is noticeable that the whole process takes place in the natural environment.Specifically,to construct the landfill,a deep rectangular hole needs to be dug,which is cut into a large piece of natural rock.After that,a clay layer and a synthetic lining are placed against the rock,while at the bottom of the landfill are some drainage pipes and a drainage tank.

Once the construction is done,trucks carrying household waste can dump household waste into the landfill for storage and the waste liquid is held in the drainage tank.Finally,the tank is sealed with a clay cover,leaving a vent connecting the outside to allow the gases inside to discharge.

To sum up,it is a relatively simple way to build and use a landfill to dispose of residential waste,which does not involve a complicated process or various materials and equipment.
