中 1 - 次の英文を読んで, あとの問題に答えなさい。 9 You may wonder what volunteer activities are. Goigg to areas that have been hit by an earthquake or flood to help the recovery work? Visiting homes for la and disabled people and helping to look ater them?

Teach them soccer or baseball. Or help them with their stadies. These too are very important and useful volunteer activities. There is a school that has a very active volunteer club in Mie. Students of this club make pieces of woodwork such as benches and chairs by using scrap wood. And they give those things to various homes and institutions as presents. The students have been able to learn the importance of making things with their own hands. They also say that 天is alot offnn. So volunteer work is not only for other people.

間 JH OUT culture, where the use ot dictionaries 1S WideSDread。many people may have the impression that a word's meaning is simply its dictionary definition.A little thought should show however, that there must be more to meaning than this. It is true that when someone wants to find out what き Word means, an easy and practical way to do it is to look the word up ina dicionary. Most people in our caltare accept dictionaries as providing unauestionably authoritative accounts of the meanings of the words they define. [2] Thenoleof dictionaries/ in our society as authorities on meaning 1eads many people to feel that the dicionary dehnition of a word more accurately represents the word's meaning than does an individual speaker's nderstanding of the word. Keep in mind/ however。 that the people who write dictionaries arrive at their definitions by studying the ways speakers of the language use different words. Some dictionaries are relatively prescriptive\、 others more descriptive* but all must face the fact that a word means what people use it to mean。 There simply is no higher authority than the general community of native speakers of the language. This is obyiously the position one must take in descriptive analysis、 but even in prescriptive grammar, words cannot be given strange defimitions that dont correspond to actual uses of those words by the speech community. A word's meaning is determined by the people who use that word, not by a dictionary- [3] The iqea that a dictionary definition is all there is to a word's meaning runs into even more serious problems when one considers that im order to understand the dictionary definition of a word, one must know the meanings of the words used in that definition: For example. 下 the word ecfo7xere is defined as 'a blastomere that develops into ectoderm'、one must ee he 0 Me 0 Pd Side

[4」 。 Ta word's meammng is its dictionary definition, then understanding this meaning involves understanding the meanings of the words used in the definitions. But understanding the meanings of these words must involve understanding the meanings of the words in 妨e7 definitions. And understanding 7ese definitions must involve understanding the words they use, which of course would have to involvye understanding even more definitions. The process is never-ending. [5] Sometimes the circularity* of a set of dictionary definitions is apparent by looking up just a few words. For instance, one English dictionary defines gzozze as being or having the nature of a deity*、 but defines gez/y as "divinity*. Another defines przde as the quality or state of being proud', but defines proxd as *feeling or showing pride'、Examples hke these are especially graphic\。but essentially the same problem holds for any dictionary-style definition. Dictionaries are written to be of practical aid to people who already speak the language, not to make theoretical claims about the nature of meaning. People can and do learn the meanings of some words through dictionary definitions, so Would be unfair to say that such definitions are completely unable to characterize the meanings of words, but it should be clear that dictionary definitions cant be all there is to the meanings of all the words in a language.
