Numeration
One of the first great intellectual feats of a young child is learning how to talk, closely followed by learning how to count. From earliest childhood we are so bound up with our system of numeration that it is a feat of imagination to consider the problems faced by early humans who had not yet developed this facility. Careful consideration of our system of numeration leads to the conviction that, rather than being a facility that comes naturally to a person, it is one of the great and remarkable achievements of the human race.
It is impossible to learn the sequence of events that led to our developing the concept of number. Even the earliest of tribes had a system of numeration that, if not advanced, was sufficient for the tasks that they had to perform. Our ancestors had little use for actual numbers; instead their considerations would have been more of the kind Is this enough? rather than How many? When they were engaged in food gathering, for example. However, when early humans first began to reflect on the nature of things around them, they discovered that they needed an idea of number simply to keep their thoughts in order. As they began to settle, grow plants and herd animals, the need for a sophisticated number system became paramount. It will never be known how and when this numeration ability developed, but it is certain that numeration was well developed by the time humans had formed even semi-permanent settlements.
Evidence of early stages of arithmetic and numeration can be readily found. The indigenous peoples of Tasmania were only able to count one, two, many; those of South Africa counted one, two, two and one, two twos, two twos and one, and so on. But in real situations the number and words are often accompanied by gestures to help resolve any confusion. For example, when using the one, two, many type of system, the word many would mean, Look at my hands and see how many fingers I am showing you. This basic approach is limited in the range of numbers that it can express, but this range will generally suffice when dealing with the simpler aspects of human existence.
The lack of ability of some cultures to deal with large numbers is not really surprising. European languages, when traced back to their earlier version, are very poor in number words and expressions. The ancient Gothic word for ten, tachund, is used to express the number 100 as tachund. By the seventh century, the word teon had become interchangeable with the tachund or hund of the Anglo-Saxon language, and so 100 was denoted as hund teontig, or ten times ten. The average person in the seventh century in Europe was not as familiar with numbers as we are today. In fact, to qualify as a witness in a court of law a man had to be able to count to nine!
Perhaps the most fundamental step in developing a sense of number is not the ability to count, but rather to see that a number is really an abstract idea instead of a simple attachment to a group of particular objects. It must have been within the grasp of the earliest humans to conceive that four birds are distinct from two birds; however, it is not an elementary step to associate the number 4, as connected with four birds, to the number 4, as connected with four rocks. Associating a number as one of the qualities of a specific object is a great hindrance to the development of a true number sense. When the number 4 can be registered in the mind as a specific word, independent of the object being referenced, the inpidual is ready to take the first step toward the development of a notational system for numbers and, from there, to arithmetic.
Traces of the very first stages in the development of numeration can be seen in several living languages today. The numeration system of the Tsimshian language in British Columbia contains seven distinct sets of words for numbers according to the class of the item being counted: for counting flat objects and animals, for round objects and time, for people, for long objects and trees, for canoes, for measures, and for counting when no particular object is being numerated. It seems that the last is a later development while the first six groups show the relics of an older system. This persity of number names can also be found in some widely used languages such as Japanese.
Intermixed with the development of a number sense is the development of an ability to count. Counting is not directly related to the formation of a number concept because it is possible to count by matching the items being counted against a group of pebbles, grains of corn, or the counter's fingers. These aids would have been indispensable to very early people who would have found the process impossible without some form of mechanical aid. Such aids, while different, are still used even by the most educated in today's society due to their convenience. All counting ultimately involves reference to something other than the things being counted. At first it may have been grains or pebbles but now it is a memorised sequence of words that happen to be the names of the numbers.

Write the correct letter, A-G, in boxes 27-31 on your answer sheet.
题目定位词:developed system, numeration
答案所在位置:B 段最后一句 话“…but it is certain that numeration was well developed by the time humans had formed even semi-permanent settlement.”
题解:答案B
这道题目比较难。因为即使根据定位词找到B 段的相关内容,仍然不好确定正确答案。因为定位词前后的话在选项里面没有。此处关键是对“…by the time humans had formed even semi-permanent settlement.”(……到人类处于半永久定居状态的时候 ) 的理解。其实该句话的前面一句对“semi-permanent settlement”是有解释的——“As they began to settle, grow plants and herd animals…( 当早期人类开始定居下来,种植作物和放牧动物 )”。所以答案 B 里面的“farming”和文章里面的“grow plants”是对应的。但是此题很容易误选为 C,因为从表面上来看 A developed system of numbering was necessary for the development of arithmetic. ( 一个发达的数字体系对于算术的发展是必要的 )。并且从 E 段最后一句话好像还能找到证据“…the development of a notational system for numbers and, from there, to arithmetic. (数字的符号学体系的发展,然后,才是算术 )”。但是一定要 注意此处的说法是对某一个人“the inpidual”而不是针对 整个的数字体系和算术体系,所以 C 不对。
题目定位词:hand signal
答案所在位置:C 段中间和最后一句“…the number and words are often accompanied by gestures…”“This basic approach is limited in the range of numbers that it can express…”
题解:答案 E
根据题目定位词可以迅速找到 C 段的“gestures”, 但是此句话只说“在实际情况下”,没有说在哪种情况下。 接下来举了一个具体的例子,说明只有在“…is limited in the range of numbers that it can express…( 仅限于手势可以表达的数字范围之内 )”,这和题目中的“…when the range of number words was restricted.( 当数字用词的范围是有限的时候 )”是对应的,所以答案选 E。
题目定位词:In seventh-century Europe, the ability to count
答案所在位置:D 段最后两句话
题解:答案 A 这道题目很好定位,但是答案比较难选。因为对 A 中的“fulfil a civic role”不容易理解是什么意思。根据题目中的“ability”可以判断这道题是关于人的,那么从语法和意义上可选的答案有 A,B,C,但是 B 和 C 所表 达的内容不仅仅限于 7 世纪,所以不对。此处的“fulfil a civic role ( 履行一个公民的职责 )”就是指“as a witness in a court ( 在法庭上当证人 )”,所以答案选 A。
题目定位词:numbers as concepts
答案所在位置:E 段最后一句 话“When the number 4 can be registered in the mind as a specific word, independent of the object being referenced…”
题解:答案 C
此题解题的关键是对题干理解——“Thinking about numbers as concepts separate from physical objects(把数字作为一个抽象的概念和具体的物体分开)”。理解了之后就可以很快定位到 E 段了。因为整个这一段都是讲述怎样把数字和数字所指的物体分开的,在最后一句话做出总 结,个体对于数字的掌握是这样的:把数字和物体分开—— 建立数的符号体系—— 算术。那么最后一句话和题干的意思是一致的,只不过省略了中间的一步—— 建立数的符号体系。
题目定位词:expressing, differently, class of item
答案所在位置:F 段
题解:答案 G
根据定位词“class of item”可以找到答案所在位置 ——F 段的“…contains seven distinct sets of words for numbers according to the class of the item being counted…”, 此句话和题干的意思是一致的。那么怎么选择答案呢?该段主要是举了一个钦西安语的例子,是为了说明抽象的记数是后来发展的体系,而根据事物的分类进行记数是古老的体系遗留下来的,这和 G 选项“…was a characteristic of early numeration systems. (……是早期记数体系的一个特征 )”是一致的,所以答案选 G。
