Composting(制作堆肥) is using household or garden waste to produce materials that can later be added to enrich the soil with nutrients. __16__ It can also reduce household or garden waste. When it comes to how to speed up the composting process, here are some tips.
● Sort out materials in order of speed of decomposition. Food items should be kept aside from garden waste. __17__ Therefore, keeping it separate from food waste will allow usable compost to be available in a much shorter time.
● __18__ Oxygen supply can be aided through the incorporation of these holes or gaps. If the compost bin is made of bricks, the bricks can be positioned with small gaps in between to let go through. As for the wooden compost bin, holes can be drilled into the sides to provide natural gaps.
● Control water and temperature. On hot, dry days, the compost bin should be positioned out of direct sunlight to keep wet. __19__ On cooler days, position the compost bin somewhere with exposure to sunlight at some point during the day to increase microbial(微生物的) activity.
Obviously, as well as the nutritional benefits, composting is an easy way to contribute to the local environment. __20__ What’s more, some level of attention is needed to ensure that the results are effective and non - problematic. Lastly, it is important to check with local authorities that composting at home is permissible(许可的).
A. Compost needs warmth, too.
B. It can balance the soil structure.
C. Bring in oxygen as much as possible.
D. Include some holes or gaps in the compost bin design.
E. Though relatively easy to do, composting can be time - consuming.
F. Garden waste generally has something which is harder to break down.
G. These units are specially designed to compost indoors by controlling unwanted smells.

答案： 16. B 下一句提到它也可以减少家庭或园林垃圾，根据下一句中的关键词also可知，空处也应是制作堆肥的好处，故B项“它可以平衡土壤结构”引出下文，符合语境。
17. F 上一句提到餐厨垃圾应与园林垃圾分开存放，下一句提到把餐厨垃圾与园林垃圾分开能够在更短的时间内获得堆肥。结合选项可知，F项“园林垃圾通常含有一些难以分解的东西”解释了要把餐厨垃圾和园林垃圾分开的原因，与下一句形成因果关系，符合语境。下一句中的Therefore是关键词。
18. D 根据上下文可知，空处是本段主旨句，且为祈使句，故应从C项和D项中选出答案项。通读本段可知，本段主要介绍了两种类型的堆肥桶：砖制的和木制的。砖制堆肥桶可以在砖之间留小的间隙，让空气通过；木制堆肥桶可以在侧面钻洞，以提供自然的空隙来让空气流通，故D项“在堆肥桶设计中加入一些孔洞或缝隙”符合语境，可作本段主旨句。D项中的some holes or gaps和下一句中的these holes or gaps相呼应。
19. A 根据上一句可知，在炎热干燥的日子里，堆肥桶应放置在避免阳光直射处以保持潮湿；根据下一句可知，在较冷的日子里，要将堆肥桶放置在白天某个时刻有阳光照射的地方。由此可推知，空处所填的内容应解释为什么在较冷的日子里又要将堆肥桶放置在白天某个时刻有阳光照射的地方，结合选项可知，A项“堆肥也需要热度”承上启下，符合语境。
20. E 上一句提到制作堆肥的一个好处——这是为当地环境作出贡献的一种简单方法，下文提到了堆肥需要注意的两个问题：给予一定程度的关注；确保在家制作堆肥是被当地政府允许的。再根据下文中的What’s more和Lastly可推知，空处所填的内容也应是在家制作堆肥需要关注的问题，结合选项可知，E项“尽管(制作堆肥)比较简单，但它很耗时”承上启下，符合语境。E项中的easy是关键信息。
