Question

【题目】Why Is Sorting Important When Recycling?

We all agree that we should recycle more at home, in the office or when out and about. 【1】Consequently, they can be collected and taken to the right place for recycling. This is what the process of sorting allows us to do.

【2】And the effective sorting needs to happen first, in our own home and second, in sorting plants to which waste is collected. When you put a plastic bottle in the right recycling bag or bin, you are helping sort recyclables so that the right material can be fed into the right recycling process. If sorting does not happen，a lot of recyclable materials can end up in landfills. It will lead to valuable resources lost from our economy.

【3】For instance, in Brussels consumers put plastic packaging, cans and beverage cartons in blue bags designed for recyclable packaging; paper in yellow bags for recycling; and glass needs to be taken to specific collection bins. Somewhat differently, in Vienna (Austria), citizens can expect their paper, metal, glass and plastic to be separately collected in different weeks of the year.【4】．

Once recyclable materials are collected from your home, they are further sorted in specialized facilities which ensure the quality of the recycling process. 【5】Traditionally, sorting has been done either manually with workers sorting what can be recycled and picking out the materials to be discarded or mechanically. Today, however, new sorting technologies are being developed in order to speed up the process of sorting but to also cause better results. Exciting technologies using magnets or optical systems are being used to effectively sort materials so more of it can be recycled.

A．For effective recycling we need effective sorting.

B．Packaging at work is the first step towards recycling.

C．This is where different sorting techniques come into play.

D．So citizens need to be aware of their local collection system.

E．Collection systems can be very different from country to country.

F．The rest was landfilled or burned even though they could have been recycled or reused.

G．But for materials to be recycled, they first need to find their way to the right waste stream.

【解析】

本文是说明文。文章讲述了在环保方面垃圾回收分类的重要性及如何具体分类。

【1】根据上文We all agree that we should recycle more at home, in the office or when out and about.（我们都同意我们应该在家里、办公室或外出时回收更多的垃圾）及下文Consequently, they can be collected and taken to the right place for recycling.（因此，可以将它们收集起来并送到正确的位置进行回收）可知，我们都赞同多回收垃圾，但是要回收材料，首先需要找到正确的废物来源。G项But for materials to be recycled, they first need to find their way to the right waste stream.（但是要回收材料，他们首先需要找到正确的废物来源）符合文意。故选G。

【2】根据下文And the effective sorting needs to happen first, in our own home and second, in sorting plants to which waste is collected.（有效的分类首先需要在我们自己的家里进行，其次需要在收集垃圾的工厂里进行）可知，本段在讲述垃圾如何分类。A项For effective recycling we need effective sorting.（为了有效回收，我们需要有效分类）符合文意。故选A。

【3】根据下文For instance, in Brussels consumers put plastic packaging, cans and beverage cartons in blue bags designed for recyclable packaging; paper in yellow bags for recycling; and glass needs to be taken to specific collection bins.（例如，在布鲁塞尔，消费者将塑料包装、易拉罐和饮料纸箱放在设计用于可回收包装的蓝色袋子中；将纸张放在黄色袋子中进行回收；玻璃需要被带到特定的收集箱中）可知，此处列举了布鲁塞尔、维也纳等地的不同收集方法，也就是说不同国家的收集系统可能非常不同。E项Collection systems can be very different from country to country.（收集系统可能因国家而异）符合文意。故选E。

【4】根据上文Somewhat differently, in Vienna (Austria), citizens can expect their paper, metal, glass and plastic to be separately collected in different weeks of the year.（有些不同的是，在维也纳(奥地利)，市民可以期望他们的纸、金属、玻璃和塑料在一年中不同的星期被分别收集）可知，不同国家的收集系统可能非常不同，因此人们需要了解自己当地的收集系统。D项So citizens need to be aware of their local collection system.（因此，市民需要了解其当地的收集系统）符合文意。故选D。

【5】根据上文Once recyclable materials are collected from your home, they are further sorted in specialized facilities which ensure the quality of the recycling process.（一旦可回收的材料从您的家中收集，他们进一步分类在专门的设施，以确保回收过程的质量）及下文Traditionally, sorting has been done either manually with workers sorting what can be recycled and picking out the materials to be discarded or mechanically.（传统上，分拣工作要么由工人手工完成，对可回收的材料进行分拣，挑选出要丢弃的材料，要么用机械方法）可知，在专门的设施里，不同分类技术发挥各自的作用。C项This is where different sorting techniques come into play.（这是不同分类技术发挥作用的地方）符合文意。故选C。

七选五题型主要考查上下文的理解与推断，虽然文章整体难度一般低于阅读理解，但是却给很多同学造成了很大的心理障碍。七个选项中选五个，比四个选项中选一个，感觉干扰性更大，很多同学在做这个题目时，总有一种眼花缭乱、心烦气躁的感觉，致使往往正确率不高。在这里提醒同学们，首先要克服心理障碍，同时要注意方式方法。其次，注意设空前后的句子，因为这些句子之间是顺承和联系的，所有一定要联系和理解上下文的语境。例如第4小题，根据上文Somewhat differently, in Vienna (Austria), citizens can expect their paper, metal, glass and plastic to be separately collected in different weeks of the year.（有些不同的是，在维也纳(奥地利)，市民可以期望他们的纸、金属、玻璃和塑料在一年中不同的星期被分别收集）可知，不同国家的收集系统可能非常不同，因此人们需要了解自己当地的收集系统。D项So citizens need to be aware of their local collection system.（因此，市民需要了解其当地的收集系统）符合文意。故D选项正确。
