現(xiàn)在人們都非常喜歡使用環(huán)保的產品，比如竹杯。令人驚訝的是，竹杯并沒有我們想象中的那么無公害。讓我們一起到文章中一探究竟吧！

難詞探意

1. mug /m·g/ n. 杯子

2. evaporate /··v·p·re·t/ v.（使某物）蒸發(fā)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 fastestgrowing 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， Stiftung Warentest 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 finelyground 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 Stiftung Warentest 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.

Stiftung Warentest 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.

Ⅱ. Difficult sentences

With descriptions such as “bamboo mug” or “made from bamboo fibers”，producers cover the fact that the cups are made from a powder of finelyground bamboo fibers that are then glued together.

由于有“竹杯”或“竹纖維制造”等描述，生產商掩蓋了這樣一個事實：杯子是由細磨的竹纖維粉末制成，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復合結構，that the cups are made from a powder of finelyground bamboo fibers that are then glued together是同位語從句，修飾說明fact，而在這個同位語從句中，又包含了一個定語從句that are then glued together。
