六级长篇阅读

关于英语六级长篇阅读段落信息匹配题这一题型的备考，不少同学可能不知道如何下手。下面小编帮大家分析一下。该题型的解题基本思路是：先快速地将题干读一下，划出关键词；然后采用skimming和scanning的方式通读原文，配对信息。本文将结合英语四六级改革样卷深入探讨如何判断关键词，为同学们指点迷津。

【如何判断关键词】

什么是关键词呢？关键词是用来帮助我们定位信息的词汇。最理想的情况是：我们依靠所划的关键词迅速定位到信息所在的段落，从而得到答案。这就要求我们所划的关键词是独一无二的，它只出现在原文的某一个段落。那么什么样的词才有这个特点呢？我们结合英语四六级改革样卷来总结一下关键词的类型。

六级样卷长篇阅读

【关键词的类型】

1. 一些拼写较长的词，比如：internship，competitiveness，globalization，integration，sustainability，innovative，immigration等。这些词属于低频词，一般不会大篇幅地出现。利用这些词可以高效地查找匹配段落。另外，这

些词有时会作为生词在文中标注出来，像internship，在原文中用斜体印刷，并以括号备注中文。我们选它做关键词，瞬间就能找到原文出处了。

2. 数字，包括年代、百分比、特殊事件等。如四级样卷中的：mid-1970s,

3.9 percent，20 percent，September 11等。教研君利用这些数字进行定位，测得的准确率是100%哦！

3. 以连字符连接的特殊词汇。如：university-based，one-child。这些词是由两个（或三个）单词连接的新词，一般当成形容词使用。三个单词的例子如：hard-to-grasp难以理解的。这些词也属于低频词，一般不会大篇幅出现。需要注意的是有时候我们需要将这些词拆开来定位，如one-child在原文中是没有的，原文是这样的“They often compromise by having just one child.”这里的one child就不是整体作为形容词使用了。

4. 研究、报告、书籍型词汇，如：report，study，books等。一般来说研究、报告等内容都是易考点，这些信息经常出现在特定的段落里，所以根据这些词汇作为关键词也很容易定位。

5. 最高级，如best，worst，most等。如六级第54题，关键词之一为the best solution。然而仅凭此关键词我们可能无法迅速地找到答案，因为原文的表述是the most effective method，用的词汇是完全不一样的。这时，我们还需要增加一个关键词pension，帮助我们定位。这就提醒我们在平常的阅读中应多关注最高级出现的地方，因为它常常是考点。

6. 除了以上所列的承载主要信息的名词，形容词等。如：funding，unsteady , values，employers，older workers，reforms，shortage，war，immigration，rich countries等。这些词的判断需要大家多加练习与体会。

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.
