5 Many linguists predict that at least half of the world's 6,000 or so languages will be 1-11 デッド dead or dying by the year 2050. Languages are becoming extinct at twice the rate of endangered mammals and four times the rate of endangered birds. If this trend 20 continues, the world of the future could be dominated by a dozen or fewer languages. Even higher rates of linguistic devastation are possible. Michael Krauss, director of 1-12 ディバステーション the Alaska Native Language Center, suggests that as many as 90 percent of languages could become moribund or extinct by 2100. According to Krauss, 20 percent to 40 percent of languages are already moribund, and only 5 percent to 10 percent are "safe" in the sense of being widely spoken or having official status. If people "become wise 10 and turn it around," Krauss says, the number of dead or dying languages could be more like 50 percent by 2100 and that's the best-case scenario. The definition of a healthy language is one that acquires new speakers, No matter 1-13 how many adults use the language, if it isn't passed to the next generation, its fate is already sealed. Although a language may continue to exist for a long time as a second 15 or ceremonial language, it is moribund as soon as children stop learning it. For example, out of twenty native Alaskan languages, only two are still being learned by children. Although language extinction is sad for the people involved,) why should the rest of us care? What effect will other people's language loss have on the future of people who speak English, for example? (A)Replacing à minor language with a more widespread one may even seem like a good thing, allowing people to communicate with each other more easily. But language diversity is as important as biological diversity. Andrew Woodfield, director of the Centre for Theories of Language and Learning 1-14 in Bristol, England, suggested in a 1995 seminar on language conservation that people do not yet know all the ways in which linguistic diversity is important. "The fact is, no s one knows exactly what riches are hidden inside the less-studied languages," he says. Woodfield compares one argument for conserving unstudied endangered plants (that they may be medically valuable with the argument for conserving endangered languages. "We have inductive evidence based on past studies of well-known languages that there will be riches, even though we do not know what they will be. (B) It seems paradoxical but it's true. By allowing languages to die out, the human race is destroying things it doesn't understand," he argues. Stephen Wurm, in his introduction to the Atlas of the World's Languages in Danger 1-

集合、数直線に関する問題(1)です。絶対値を含んだ不等式について確認したいことがあります。 問題文で最初に【aは整数である】とありますが、 そのあとIxI<=a/2と書いてある時点でaが正の整数であると決定して良いのですか?

3 数直線と命題 (1) zを実数aを整数として, 集合P, Q, R をそれぞれ P={x\/x-1³/≥3}, Q={x\x²+18x+79≥0}, R= 2 である. とするとき,P∩QCR を満たすαの最小の値は (2) 命題「3<x<4ならば, 2a<x<3a である」 が真となる定数aの値の範囲は「 la/> 実数の集合は、 数直線上で考えよう や共通部分, 和集合, 補集合などが視覚的に考えられるようになり, 分かり易くなる. 例えば, の集合A={x|3<x<4},B={x|2<x<5} について, ACBが成立する ・ 成 不等式の命題は、 数直線上の区間どうしの関係からとらえる 「3<x<4ならば, 2<x<5である」 という命題の真偽は、 数直線上で,2つ 7 Pは 「x≦または いまは、 右図により, この命題は真である. このように, 不等式で表された命題については, 数直線上 立しないと一致する. つまり, 区間3<x<4が区間2<x<5の中に含まれる ・ 含まれないに一致する の区間の包含関係によって視覚的にとらえることができる. 含まれる条件は, 19 2 解 答 (1) 212223のとき x+18r+79≧0のとき,x≦-9-√2 または-9+√2≦x α=-9-√2,β=-9+√2 とおくと, 19 たはHS」 2 Qは 「x≦a またはB≦x」 であり, 数直線上に図示すると図1のようになる.
