(2020·太原市高三阶段性测评)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 recyclable things 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 (废物填埋地)．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 specialised 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 also to cause better results.Exciting technologies using magnets (磁铁) or optical systems are being used to effectively sort materials so more of them can be recycled.
A．For effective recycling we need effective sorting.
B．Packaging 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 were 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 bin.
语篇解读：本文介绍了回收再利用时分类很重要，且各国收集废品的方法可能不同，因此居民需要了解当地的收集方法，这样有利于高效地保护环境，同时有利于节约资源。
1．选G 根据空后的“Consequently”可知，空后讲“结果”，则空处应是讲“原因”，故G项“但是对于要回收利用的材料来说，首先它们需要找到方法来通往恰当的垃圾箱”符合语境，并与空后一句“因此它们才能被收集并被带到恰当的地方进行回收利用。”逻辑关系紧密。故选G项。
2．选A 上段讲了回收再利用和垃圾分类，本段讲的是有效的垃圾分类，故此空应填一个过渡句。A项中的“effective sorting”与空后的“the effective sorting”相呼应，故选A项。
3．选E 本段通过列举比利时的首都布鲁塞尔和奥地利的首都维也纳这两个城市不同的收集废品的方法以表明各国收集废品的方法可能不同，故E项“(废品)收集方法在国与国之间可能非常不同”可概括本段。故选E项。
4．选D 空处为段落尾句，该段讲的是(废品)收集方法在国与国之间可能非常不同，设空处与前文应为因果关系，因此，居民需要了解当地的收集方法。故选D项。
5．选C 空前讲将可回收材料在专用的设备中进行分类，空后是说垃圾分类分人工分类和机器分类两种，故C项“这就是不同的分类技术开始起作用的地方”可以衔接前后句。故选C项。
