  英語六級段落匹配精選題原文

  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 more 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 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 the preponderance 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 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 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 together, 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. We 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 "why 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 uneconomic to remove the lignin for many paper and card applications.

  G*** It also means, of course, that lignin-free paper is going to be more expensive, but that is nevertheless what the archivist must look for in his supplies. There is no point whatsoever in carefully placing our valuable artifacts in paper or card that is going to hasten their demise. Acid is particularly harmful to photographic materials, causing them to fade and is some cases simply vanish!

  H*** So, how do we tell a piece of suitable paper or card from one that is unsuitable? You cannot do it by simply looking, and rather disappointingly, you cannot always rely on the label. "Acid-free" might be true inasmuch as a test on the paper may indicate that it is a neutral material at this time. But lignin can take years before it starts the inevitable process of breaking down, and in the right conditions it will speed up enormously.

  I*** Added to this, as I have indicated earlier, paper may also contain other materials added during manufacture such as bleach, china clay, chemical whiteners and size. This looks like a bleak picture, and it would be but for the fact that there are suppliers who will guarantee the material that they sell. If you want to be absolutely sure that you are storing in, or printing on, the correct material then this is probably the only way.

  J*** Incidentally, acids can migrate from material to material. Lining old shoe boxes with good quality acid-free paper will do little to guard the contents. The acid will get there in the end.

  Paper from Rag

  K*** Paper is also commonly made from cotton and rag waste. This has the advantage of being lignin-free, but because there is much less cotton and rag than trees, it also tends to be much more expensive than wood pulp paper. You will still need to purchase from a reliable source though, since even rag paper and card can contain undesirable additives.

  L*** A reliable source for quality rag papers is a recognized art stockiest. Many water color artists insist on using only fine quality rag paper and board.

  M*** The main lesson to learn from this information is that you cannot rely on purchasing archival materials from the high street. The only safe solution is to purchase from specialist suppliers. It may cost rather more, but in the end you will know that your important and valuable data and images have the best home possible.

  英語六級段落匹配精選題選項

  1. The corn-flake packet is cheaper than high grade card.

  2. There are a lot of materials which can be used for making paper, but the superiority ones are soft wood, cotton and rags.

  3. During the whole manufacturing process, the final product is made from a pulp of cellulose fibres.

  4. In order to make white paper and card, the makers will add bleach.

  5. Liguin is essential for the tree but it will make paper easy to break.

  6. Many paper producers will preserve lignin during manufacture, because leaving the lignin will make more paper from a tree.

  7. Acid is particularly harmful to photographic materials.

  8. If the lignin is removed from the paper, the paper will be more expensive.

  9. Although free of lignin, paper made from cotton and rag waste can also cost more money than wood pulp paper because there is much less cotton and rag than trees.

  10. What we can learn from "Paper from Rag" is that you had better buy archival materials from specialist suppliers.

  英語六級段落匹配精選題答案

  1.B

  根據題幹中的資訊提示詞corn—flake packet,high grade card,可定位到文章第二段,該部分最後提到corn-flake packet在製造過程中比高等級的紙***high grade card***便宜.

  2.C

  根據題幹中的資訊提示詞soft wood,cotton and rags,可定位到文章第三段最後一句。

  3.D

  根據題幹中的資訊提示詞final product,可將答案定位到D段,第二、三句提到最後的產品來源於纖維素紙漿。

  4.D

  根據題幹中的資訊提示詞white paper and card,可將答案定位到D段,該部分最後提到為了得到白紙,紙張生產者在製造過程中添加了漂白粉和其他化學物質。

  5.E

  根據題幹中的資訊提示詞essential for the tree,可將答案定位到E段,該部分提到木質素是木頭的主要組成物,其作用是凝聚纖維素,但它會使紙張變得易碎。

  6.F

  根據題幹中的資訊提示詞lignin,可將答案定位到F段,該部分最後提到許多紙張生產者在生產過程中會保留木質素,主要是因為它會增加樹木的造紙產量。

  7.G

  根據題幹中的資訊提示詞acid,可將答案定位到G段,該部分最後提到酸對相紙的原料尤其不利。

  8.F

  根據題幹中的資訊提示詞lignin和paper可定位到文章的F段,因為該段提到,如果在紙張的生產中去除木質素,將會降低樹木出產紙張的量,由此可以知道,去除了木質素的紙張價格必定會更加昂貴。

  9.K

  根據題幹中的資訊提示詞cotton and rag waste可定位到文章的K段,該部分告訴我們,儘管用棉花和破布料造的紙裡沒有木質素,但它們要比木製的紙貴很多,這是因為棉花和破布料的數量比樹木少得多,由此可以得出答案。

  10.M

  根據題幹中的資訊提示詞Paper from Ra9可定位到文章的最後一段,該部分提出最好到專業的供應商那裡去買檔案材料,由此可以得出答案。
