（三）定冠词(Definite Article)
1) 定冠词的基本特性
实际上所有名词（专有名词将另行讨论）前都可能用定冠词the。究竟用不用定冠词，主要取决于我们所表达的思想。如果我们要给予某个名词以明确的、限定的、特指的
a) 一般用于带有修饰语的名词词组前，但并非所有带修饰语的名词都需要the。例如：
Don’t you think Georgian houses are absolutely lovely?
Stainless steel (不锈钢器皿) has many uses.
I can’t say I care for modern art.
上面三句中斜体部分的名词虽然都有修饰语，因没有明确限定而是泛指一类事物，故不用the。下面三句斜体部分的名词则表示提到过的，特指的事物，要用the：
The Georgian houses have been sold.
The stainless steel was beautiful, but I thought most of the glass （玻璃器皿）they
exhibited was rather unimaginative.
They showed a wonderful selection of the impressionists, but the modern art was too
limited in its range.
b) 也用于有后置修饰语的名词词组前。例如：
The old houses which are most worth visiting are in the Imperial City.
The steel of the gun barrels has gone rusty.
The art of the eighteenth century has never been surpassed（超过）．
上面三句中的形容词从句和介词短语明确了是什么样的房子（what houses），什么
样的钢（what steel）和什么样的艺术（what art），故用the。下面三句同样有形容词从句和介词短语修饰名词，但是它们只指这些名词属于某一类事物，并非特指，故不用the。例如：
Houses which fail to satisfy these minimum requirements are to be pulled down.
Steel of great strength is needed for the manufacture of guns.
Art in the eighteenth century probably played a more important part in people’s lives than it does today.
EXERCISE 4
Fill in the blanks with the where necessary:
1. The engineers found that steel was of insufficiently high quality.
Steel, I suppose, is the most important single product of the modern industrial world.
2. Large forests can have an important influence on climate.
Forests have all been cut down.
3. Nature was probably his chief source of inspiration （灵感，鼓舞）.
Nature of the problem was such as to arouse his interest.
4. Education of little children has been greatly neglected.
Public education must be greatly extended.
5. The exploration（探索）of space has become one of the chief topics of science
fiction（科幻小说）.
Space between the table and the wall was just big enough for a small bed.
6. I prefer classical music to pop music.
Film wasn’t very good but I liked music.
7. My favourite subject at school was history.
All students should know something about history of their own country.
8. I cannot judge accuracy of your calculations（计算）.
In mathematics accuracy is essential.
2) 定冠词的主要用法
a) 用于单数名词前，表示“某一类人或物”，以区别于其他人或物。例如：
The tiger is a fierce（凶猛的）animal. （相当于A tiger is a fierce animal.或Tigers are fierce animals.）
In this tribe the woman goes out hunting and the man stays at home to look after the
children.
下面三句中的斜体部分不能互换：
Who invented the radio? （指类别）
Who had a radio? （指同类中的任何一个）
Who manufactured radios?（指这一类中的所有个体）
man 指“人类”时，不用the。例如：
Man will conquer nature.
b) 用于指世上独一无二的东西，如the moon，the sun，the world等。
c) 用于表示“乐器”的名词前，但一般不用于表示“体育运动”的名词前。例如：

d) 用于某些形容词前，可表示“一类人”。例如：
The young are impatient；they want changes.
e) 一般不用于表示“疾病”的名词前。例如：
I’m just recovering from rheumatism（风湿病）.
下列病名前一般用a／an：
I have an ache in my head (a pain in the neck).
He has a cold／a fever.
特指时需要用the。例如：
Jim has never really got over the malaria（疟疾）he caught in the East.
f) 一般不用于表示“膳食”的名词前，但有形容词修饰时用the。例如：
Breakfast is served at eight.
The wedding breakfast was held in her father’s house.
如果泛指，用a／an。例如：

g) bed, church, college, court, hospital, market, prison, school, sea和work等名词用来指有关
活动时，一般不用冠词。例如：

He spent six months in prison. （指to be punished）

Ken is a seaman. He spends most of his life at sea. （指to sail）
注：在美国英语中，通常用a／the hospital，a university。

例如：

EXERCISE 7
Cross out articles that are unnecessary in the following passage:
The people everywhere in the world might say, “When the strangers do not understand the customs that we follow, they are confused and do not understand what is happening.” The good manners are different in the different parts of the world. In many places, for example, accepting the gifts or anything important with the left hand shows the bad manners and even the rudeness. People with the good manners accept the important things with the both hands or at least with the right hand. Using the left hand to accept the important things shows not only the discourtesy （无礼，失礼）but also shows that the person who is accepting thinks the thing being given is worthless. In the Europe and the North America, however, the people do not follow this custom and give and receive with either hand without thinking about the meaning of what they are doing.

长篇阅读——匹配题 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 than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2. Passage 1 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（纤维素化合物）-based material which will include many woods, cottons and grasses of 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(碱) 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 paperback books will have a life of no 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. It also means, of course, that lignin-free paper is going to be more expensive. G) However, it 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 in 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

大学英语四级训练题参考答案
6月大学英语四级训练题参考答案作文【答案】 Living alone or Living with Roommates Nowadays, there has appeared a heated discussion among the college students as to whether they should live alone outside the campus or l ive together with other roommates in the students’ dormitory. Opinions are divided over the matter. Those who are in favor of Living alone maintain that it is very convenient to live by themselves. They can enjoy absolute freedom in a room of their own. They can have their own timetable without disturbing others. They are also free to equip the room with a personal computer so that they can have easy access to the Internet. But others argue that living with roommates has attractions of its own. With sever al students sharing the same room, each person’s experiences can be greatly enriched. They can learn a lot from talking to one another. By learning to tolerate the differences between individuals, they can become more mature.

长篇阅读——匹配题 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 than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2. Passage 1 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 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（纤维素化合物）-based material which will include many woods, cottons and grasses of which is an example and from where we get the word "paper". Many of these are very specialized, but the of paper making has been from soft wood and cotton or , 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 and then boiled with strong alkalies(碱) such as caustic soda, until a fine of 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 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 . 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 paperback books will have a life of no 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. It also means, of course, that lignin-free paper is going to be more expensive. G) However, it is nevertheless what the 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 their . Acid is particularly harmful to photographic materials, causing them to fade and in 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

大学英语四级单选题练习 1. Nowadays, cycling, along with jogging and swimming, _______ as one of the best all-round forms of exercise. A. regard B. is regarded C. are regarded D. regards 【答案】B 解析：句意：现在骑自行车，慢跑和游泳被认为是最全面的锻炼方式之一。根据动词短语regard...as...把...看作...和句意确定应该用被动语态排除A和D，再根据主语部分是由介词短语along with连接的三个动名词做主语，应该谓语动词应该就前一致，即用单数，排除C，故选B。 2.

Each paragraph is marked with a letter. 长篇阅读 Preparing for Computer Disasters A) Summary: When home office computers go down, many small businesses grind to a halt. Fortunately, taking steps to recover from disasters and minimize their effects is quite straightforward. B) Fires, power surges, and floods, they're all facts of life. We read about them in the morning paper and see them on the evening news. We sympathize with the victims and commiserate over their bad luck. We also shake our heads at the digital consequences—melted computers, system failures, destroyed data. Yet, somehow, many of us continue to live by that old mantra of denial: "It won't happen to me." Well, the truth is, at some point you'll probably have to deal with at least one disaster. That's just how it goes, and in most aspects of our lives we do something about it. We buy insurance. We stow away provisions. We even make disaster plans and run drills. But for some reason, computer disaster recovery is a blind spot for many of us. It shouldn't be. Home computers contain some of our
