1、英语四级长篇阅读段落信息匹配题练习（1） 难度：适中 来源：网络 收藏 30 Directions: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more th
2、an once. Each paragraph is marked with a letter. 长篇阅读 Paper-More than Meets the Eye A) We are surrounded by so much paper and card that it is easy to forget just how complex it is. There are many varieties and grades of paper materials, and whilst it is fairly easy to spot the varieties, it is far m
3、ore difficult to spot the grades. B) It needs to be understood that most paper and card is manufactured for a specific purpose, so that whilst the corn-flake packet may look smart, it is clearly not something destined for the archives. It is made to look good, but only needs a limited life span. It
4、is also much cheaper to manufacture than high grade card. C) Paper can be made from an almost endless variety of cellulose-based material which will include many woods, cottons and grasses or which papyrus is an example and from where we get the word paper. Many of these are very specialized, but th
5、epreponderance of paper making has been from soft wood and cotton or rags, with the bulk being wood-based. Paper from Wood D) In order to make wood into paper it needs to be broken down into fine strands. Firstly by powerful machinery and then boiled with strong alkalies such as caustic soda, until
6、a fine pulp of cellulose fibers is produced. It is from this pulp that the final product is made, relying on the bonding together of the cellulose into layers. That, in a very small nutshell, is the essence of paper making from wood. However, the reality is rather more complicated. In order to give
7、us our white paper and card, the makers will add bleach and other materials such as china clay and additional chemicals. E) A further problem with wood is that it contains a material that is not cellulose. Something called lignin. This is essential for the tree since it holds the cellulose fibres to
8、gether, but if it is incorporated into the manufactured paper it presents archivists with a problem. Lignin eventually breaks down and releases acid products into the paper. This will weaken the bond between the cellulose fibers and the paper will become brittle and look rather brown and careworn. W
9、e have all seen this in old newspapers and cheap paperback books. It has been estimated that most paper back books will have a life of not greater than fifty years. Not what we need for our archives. F) Since the lignin can be removed from the paper pulp during manufacture, the obvious question is w
10、hy is it left in the paper The answer lies in the fact that lignin makes up a considerable part of the tree. By leaving the lignin in the pulp a papermaker can increase his paper yield from a tree to some 95%. Removing it means a yield of only 35%. It is clearly 本文主要介绍了我们平常所见所用的纸的复杂性，通过介绍用木头和破布料造纸的过
11、程，使我们对纸的类别、属性有了更深入的了解。 答案参考： 1. B 根据题干中的信息提示词 cornflake packet,high grade card,可定位到文章第二段，该部分最后提到 corn-flake packet 在制造过程中比高等级的纸(high grade card)便宜. 2. C 根据题干中的信息提示词 soft wood，cotton and rags，可定位到文章第三段最后一句。 3. D 根据题干中的信息提示词 final product，可将答案定位到 D 段，第二、三句提到最后的产品来源于纤维素纸浆。 4. D 根据题干中的信息提示词 white paper
12、and card，可将答案定位到 D 段，该部分最后提到为了得到白纸，纸张生产者在制造过程中添加了漂白粉和其他化学物质。 5. E 根据题干中的信息提示词 essential for the tree，可将答案定位到 E 段，该部分提到木质素是木头的主要组成物，其作用是凝聚纤维素，但它会使纸张变得易碎。 6. F 根据题干中的信息提示词 lignin，可将答案定位到 F 段，该部分最后提到许多纸张生产者在生产过程中会保留木质素，主要是因为它会增加树木的造纸产量。 7. G 根据题干中的信息提示词 acid，可将答案定位到 G 段，该部分最后提到酸对相纸的原料尤其不利。 8. F 根据题干中的信息提示词 lignin 和 paper 可定位到文章的 F 段，因为该段提到，如果在纸张的生产中去除木质素，将会降低树木出产纸张的量，由此可以知道，去除了木质素的纸张价格必定会更加昂贵。 9. K 根据题干中的信息提示词cotton and rag waste可定位到文章的K段， 该部分告诉我们，尽管用棉花和破布料造的纸里没有木质素，但它们要比木制的纸贵很多，这是因为棉花和破布料的数量比树木少得多，由此可以得出答案。 10. M 根据题干中的信息提示词 Paper from Ra9可定位到文章的最后一段，该部分提出最好到专业的供应商那里去买档案材料，由此可以得出答案。
