    Even in this electronic era, paper continues to play a complete role in our daily lives. Americans depend on about 85 million tons of paper and paperboard a year to help us clean, organize, advertise, educate and much more, according to the Environmental Protection Agency.
    Unfortunately, this soft product comes with environmental disadvantages. These include the loss of biological variety associated with permanent forest; an energy and water intensive production process that generates greenhouse gases and other dangerous products; and a life cycle that ends in a landfill or incinerator nearly half the time.
    Of course, we have choices. We can lessen paper’s environmental blow first and foremost by reducing our dependence (using cloth towels in the kitchen, printing on both sides of the sheet at the office, etc.). And, when we really need to use paper, we can make better-educated buying decisions. Here are a few tips for purchasing eco-friendly paper:
    Buy recycled. Doing so saves landfill space, supports green jobs and " reduces the total amount of resources you’re using", says Susan Kinchella, executive director of Conse-rvatree, an organization that advocates using more paper which can be used again.     Study labeling carefully. Look for products that contain post-consumer waste (or material that has completed a full life cycle); the higher the percentage, the better. A chasing-arrows symbol may simply mean a paper product can be recycled, while the word" recycled may refer to only a small percentage of recovered fibers.
    Demand certificate. A number of organizations certify that the original fiber used in a given paper comes from responsibly managed forests. Kinsella says the one environmentalists trust most is the Forest Stewardship Council. Check with your printer or paper supplier to see whether it carries FSC-certified lines.
    Consider tree-free options. Some paper is now made from agricultural crops, several of which have a higher yield per acre than some types of trees used in papermaking and may have other benefits. Tree-free material is available for personal use (think cards and invites), but before buying, investigate its origins and the farming practices used. For a list of suppliers, check out http://www, con-servatree. org/tree free. html.
    Check color. Paper which is made whiter without the use of CI or other chemicals is less polluting. Using paper without CI is another step up. And when using a professional printer, ask for vegetable-based inks.
What can be inferred from Para. 6?
选项 A、The components and making process are on the labels of paper.
B、Paper made from daily waste is better than that from trees.
C、We should buy the paper product with a chasing-arrow on its label.
D、Recycled paper will have better influence on our nature than recyclable.
答案C
解析 推理判断题。由题干定位到第六段可知，购买纸制品其中一个原则就是要检查商品标签，查看构成成分。如果纸制品中含有大量的用后废料，也就是已经完成生命周期的材料，那就可以购买。而且这种含油量越高，对环境保护越有利。有镂雕箭头标志的纸制品是再生纸，可循环使用，而有“可循环”标志的只是说明其中含有较少量的可循环使用纤维。所以可以推断出[C]“我们应该购买对环境更有利的有镂雕箭头标志的纸制品”为答案。[A]“纸制品的标签上标明了其成分和生产过程”，文中并未提到标签上还有生产过程，故排除；[B]“用日常生活垃圾做的纸制品比用树木为原料做的好”，文中并未把二者的质量进行比较，故排除；[D]“与‘再生纸’比起来，‘可循环纸’对环境有更好的影响”，这与文章意思刚好相反，故排除。
