雅思阅读中，有不少文章是关于environment环境，environmental pollution环境污染，同时还会结合technology科技，今天Super和大家分享一篇相关话题的精选文章，一些地道用词、搭配已作出标记，便于考生积累！

【阅读专栏,干货满满】本期文章选自The Economist《经济学人》，“回收Recycling：塑料公路”。文中一些地道的用法可以用在雅思作文中哟！

20世纪50年代以来，产生的所有塑料中，只有不到10%得到回收。其中大部分都成了垃圾，大多数都倾倒在了垃圾填埋场。一些被丢弃在自然环境中，流进河里，冲刷进海洋里。塑料废物问题将在出现好转前恶化。

Of all the plastic produced since the 1950s, less than 10% has been recycled. The vast majority ends up being dumped, most of it in landfill. Some is left to litter the natural environment, where it can get into rivers and wash out into the sea.

The plastic-waste problem will worsen before it gets better

the vast majority绝大部分；end up doing sth以…而告终；landfill垃圾填埋地；litter散落在（例句：Glass from broken bottles litters the sidewalk.碎瓶子的玻璃渣散落在人行道上。）

今年可能会生产3.8亿公吨塑料。这是每年生产的1.2亿公吨沥青的三倍还多，大部分沥青都被用于建造世界范围内的公路。

其中有一个联系，塑料源自石油化工产品，而生产出的沥青是精炼油脂的副产品。两者都是聚合物，由紧密相连的分子长链组成。

Some 380m tonnes of the stuff are likely to be made this year. That is more than three times as much as the 120m tonnes of bitumen produced annually, most of which goes into building the world's roads. There is a connection. Just as plasticis derived from petrochemicals, bitumen is produced as a by-productof refiningoil. Both are polymers, which consist of long strands of molecules boundtogether firmly.

more than three times as much as是xxx的三倍还要多；bitumen沥青；be derived from源自于、由…得到；by-product副产品；refine提炼、完善；polymer聚合物；consist of由…构成、包括；bound（bind的过去式，过去分词，意为捆绑、结合）

正是这种特征让塑料牢固且寿命超常。这些特点对公路建造者而言也很有用，他们利用热沥青将由碎石子和石头组成的聚合物粘合在一起制成我们熟悉的柏油。所有这一切不禁让人联想：为什么不将一种聚合物用另一种聚合物替换掉呢？回收塑料已被用于制作一些产品，比如排水沟和排污管。现在注意力转向了公路，9月11日，在荷兰的一个城镇“兹沃勒”，由70%的回收塑料以及30%的聚合物组成的一条30米长的自行车径通车。这条公路将被用于测试一种被称为塑料公路的产品，

It is this characteristic that makes plastic strong and contributes to its great longevity. Such features are also useful for road builders, who use hot bitumen to bind together aggregates(聚合体) made from broken rocks and stones, into what is commonly known as asphalt(柏油、沥青). All of which has got some people thinking: why not swap one polymer with another? Recycled plastic is already used to make some products, such as guttering(排水沟) and sewage pipes.

contribute to有助于、促成；great longevity长寿；Swap…with…与…交换；sewage污水
