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-

ex2で質問です。 なぜvblはEを変えて電流が逆流することはないのですか?

(別解) 抵抗Rを見てみる。 bからaへ電流が流れている。 だから b が高電位。 bとQ,aとPの電位はそれぞれ等しい。 よってQが高電位 (3) PQ は等速度で動いているから、 力のつり合いが成りたつ。 電磁力は左向き に働くから、外力は同じ大きさで右向きである。 100 電磁気 B212 ∴. P=Fu=(UBI) 外力F=電磁力IBl= R R (別解) エネルギー保存則よりPはジュール熱に等しい(外力の仕事分だけジュー ル熱が発生する)。 電磁誘導ではエネルギー保存則にも気を配りたい。 以上をファラデーで考えると, PQba がコイルで, Bは一定だが面積Sが増していくため下向きに貫く磁 束が増す。 そこで上向きの磁場をつくる向き, すなわ ちP→Qの向きに電流を流そうとする (事実, 回路が 閉じているので流れる。) 4t の間の磁束の増加は右図 の斜線部に等しく, 4Φ=B×W4t V=40/4t=vBl A EX2 EX1に続いて, ab間にRの抵抗と起 電力Eの電池をつなぎ, スイッチを付 ける。 PQ をレール上で静止させた状態 でスイッチを入れる。 外力は加えない。 (1) PQ の速さがぁになったときの電流 Iを求めよ。 (2) 十分に時間がたったときのPQの速さを求めよ。 E b a a 67 EX1で導体棒 PQ がぁの抵抗をもつ場合の電流Iと,Pに対するQの電位 を求めよ。 High レールがなくてPQだけが磁場中を動いているとしよう。 コイルにあたる部分がないのにどうしてファラデーを適用 していくかというと、上のようなレールを仮想的に敷いて 考えればよい。 右の図のように右側にコイルを仮想して考 えてもよい。このようにファラデーには融通無碍な所がある。 P ゆうづうむげ ↑何ものにもとらわれなく自由 Quat B P Q V ひ 17² P 40 B 減少 右向きに電磁力を受け動き出す。 EX1 と同様, PQ を電池に PA 石巻替えると右の図になる。キルヒホッフの法則より E-Bl=RI 1.

Taylor's parents were right to believe she could succeed. At age fourteen, she got a contract with RCA Records, a major music 15 company. 5 RCA wanted Taylor to sing other people's songs until she was an adult. Taylor “ did not like this. She wanted to write and sing her own songs about her life and the boys she dated.
