（1）C． 段落大意题．根据第二段"William Chen， a professor of food science and technology at Singaporeds Nanyang Technological University， invented the environmentally-friendly food wrap． Itds made of cellulose（纤维素），a form of fiber， obtained from the waste generated by soy bean product producers． The beans are pressed to squeeze out juice thatds used to make tofu and soy milk． And whatds left is usually thrown away， but Chen takes the waste and puts it through a fermentation（发酵） process， during which cellulose is produced．新加坡南洋理工大学食品科学与技术教授威廉•陈（william chen）发明了环保型食品包装纸． 它是由纤维素制成的，纤维的一种形式，从大豆制品生产商产生的废物中获得． 豆子被压榨出用来做豆腐和豆奶的汁液． 剩下的通常会被扔掉，但 chen 会把废弃物经过发酵处理，在此过程中会产生纤维素．"可知第二段主要讲述了制作大豆包装的方法．故选C．（2）C． 推理判断题．根据第三段"Cellulose-based plastic wraps have been on the market for a few years， but Chen says that most are made from wood or corn， grown for that purpose． By contrast， his wrap is made from a waste product， which doesnnt compete with other crops for land and is more sustainable．纤维素塑料薄膜已经在市场上销售了几年，但陈先生说，大多数塑料薄膜都是用木材或玉米制成的．相比之下，他的塑料薄膜是用废弃的产品制成的，这种产品不会与其他作物争夺土地，而且更具可持续性．"可知陈的包装与其他纤维素塑料包装最大的区别它是由食物残渣制成的．故选C．（3）D． 推理判断题．根据倒数第二段" Chen adds，"The soy-based wrap costs almost nothing to make in the lab because the raw materials are free． Commercial prosecution would involve additional expenses， such as storage and quality control， however， we have not calculated those costs yet．"Chen 补充道，"在实验室里制作这种大豆包装几乎不需要花费任何成本，因为原材料是免费的． 商业检控会涉及额外开支，例如储存和品质控制，但我们尚未计算这些开支．"可知食品包装的商业化生产会带的后果是生产成本的增加．故选D．（4）D． 文章出处题．阅读全文可知本文主要讲述了使用食物残渣制作的环保型食品包装纸，这种技术既便宜又简单，能减少塑料和食品的浪费，创造一个更清洁的环境．所以是科学方面的，会出现在科学杂志上．故选D．
