阅读与读写练讲义：竹纤维杯并不环保--高考英语阅读二轮复习备考.docx

竹纤维杯并不环保现在人们都非常喜欢使用环保的产品，比如竹杯。令人惊讶的是，竹杯并没有我们想象中的那么无公害。让我们一起到文章中一探究竟吧！难词探意1. mug /m·g/ n. 杯子2. evaporate /··v·p·re·t/ v.（使某物）蒸发掉For many people， food and drinks containers made from bamboo seem like a good choice because they are considered environmentally friendly. Bamboo is the fastest growing plant on the planet， so theres no shortage of sustainable material. Plus， bamboo containers are reusable and can， therefore， replace the disposable containers used by coffee shops and other food and drink outlets.However， a recent test by the consumer group， that investigates and compares goods on the German market， has shown that by shifting to a bamboo cup you might be risking your health in the process. Having tested 12 different bamboo cup brands， Sifting Ware test found that buyers are generally given the impression that they are buying natural products. With descriptions such as “bamboo mug” or “made from bamboo fibers”， producers cover the fact that the cups are made from a powder of finely ground bamboo fibers that are then glued together. All of the cups tested contained melamine resin， a glue made from formaldehyde（甲醛）and melamine（三聚氰胺）.As reported by Food Packaging Forum， the International Agency for Research on Cancer has also recently classified melamine as being “possibly carcinogenic（致癌的）to humans”. Still， as long as certain conditions are met， melamine resin is not considered a dangerous substance. One of these conditions， however， is that it is kept under 70°C. But these bamboo cups are being specifically marketed for hot drinks. The Sifting Ware test testers did the tests where common hot coffee was added into the cups. The results showed that four of the twelve cups contained “very high amounts of melamine” after the third filling. In three of the other cups， this occurred after the seventh filling. The results were sometimes higher after the seventh test， suggesting that the harmful chemicals dont evaporate but continue to spread into drinks with prolonged use.Sifting Ware test also criticized the manufacturers for not properly warning about the dangers of placing the bamboo cups in the microwave. When heated to high temperatures， the cups material will begin to break up. As the cups surface is destroyed， it will release even more melamine and formaldehyde.Reading comprehensionStructure of the textLanguage study.

Difficult sentencesWith descriptions such as “bamboo mug” or “made from bamboo fibers”，producers cover the fact that the cups are made from a powder of finely ground bamboo fibers that are then glued together.由于有“竹杯”或“竹纤维制造”等描述，生产商掩盖了这样一个事实：杯子是由细磨的竹纤维粉末制成，然后粘在一起。本句的主干是producers cover the fact，其中With descriptions such as “bamboo mug” or “made from bamboo fibers”是with复合结构，that the cups are made from a powder of finely ground bamboo fibers that are then glued together是同位语从句，修饰说明fact，而在这个同位语从句中，又包含了一个定语从句that are then glued together。Reading check阅读短文，根据其内容写一篇60词左右的内容概要。写作导引概要寫作是对一篇文章的主题思想的简单陈述。它用最简洁的语言概括了原文的主题，主要包括三个步骤：（1）阅读;（2）写作;（3）修改成文。在进行概要写作时，可采用以下几种小技巧：（1）删除细节，只保留主要观点;（2）选择一至两个例子即可;（3）把长段描述变成简单句子;（4）使用最短连接词。Reading CheckNowadays， bamboo containers are widely used in many eating and drinking places.
