始 入外スリラン Hoshino Michio (1952-1996) is a Q Well-known nature photographer. He produced a great number of wonderful photos of wildlife in Alaska. Here, he talks about Alaska, its people, and “distant nature. 1 When I was a freshman in college, I came across a photo that changed my life. It was a beautiful photo of a small village called Shishmaref on a small island in Alaska. At first, I couldn't believe that people could live in such a remote te place. However, when I found the village on the map, I got interested and had an urge to go and visit this tiny village. I decided to write a letter, but I didn't know anyone in the village. DSo I wrote “Dear Mayor of Shishmaref,” asking him to introduce me to some family who might let me stay. Half a year later, I received a reply inviting me to visit. 1 46 In 1973, I went to Shishmaref and spent the summer with an Eskimo family. I ate the same food as they did, and even went Caribou funting with them. The local people often called me “Eskimo boy"! ②It seemed that every day brought me new experiences. ③Living in Alaska, I discovered that people lead their everyday lives even in such an out-of-the way place, just as we do back in Japan. 4) 日本語訳 アラスカに生きる 星野道夫 (1952-1996) は著名な自然写真家である。 アラスカの野生生物のすばらしい写真を数多く生み出し た。 ここでは、 アラスカ、 そこに生きる人々、 「遠い自然」 について語っている。 1 私が大学1年のときに、 人生を変える写真との出会いがありました。 それはアラスカの孤島にある、シシュマ レフと呼ばれる小さな村の美しい写真でした。 最初は、そのようなへき地で人間が暮らせることが信じられませ んでした。 けれども、 地図上でその村を見つけたときに、 興味を惹かれ、この小さな村を訪れたいという衝動に駆 られました。 手紙を書こうと決めましたが、村に知っている人などいません。 ① (なので私はシシュマレフの市長に 誰か私を住まわせてくれる家族を紹介してほしいと手紙を書きました)そして半年後、なんと私を 招待してくれるという返信を受け取ったのです。 1973年、私はシシュマレフに行き、 エスキモーの家族とひと夏を過ごしました。 彼らと同じものを食べ、いっ しょにカリブー狩りに行くことさえありました。 地元の人たちはしばしば私のことを 「エスキモーボーイ」と呼 んでくれました! ② (毎日、新しい経験を ③ (アラスカに住んだことで

この問題のウとエで、CO₃とHCO₃とCaの大小関係は示されていますが、これらの濃度と、H、OHの濃度の大小関係は証明されてないのに、なぜそうかけるのですか?

°262.〈二酸化炭素水溶液の電離平衡と鍾乳洞〉 思考 鍾乳洞は,炭酸カルシウム CaCO3を主成分とする石灰岩が二酸化炭素CO2 を含む地 しょうにゅうどう どうくつ 下水に溶かされて洞窟になったものであり, その過程は次の反応で説明できる。 ア +2 イ CaCO3 (固) + CO2 + H2O~ このことを確認するために, 透明の反応容器内で生石灰 CaO 5.6×102g を純水 1.0L (1) ase に溶解し, この溶液に不活性ガス (貴ガス) とCO2 の混合ガスを吹き込んで、 沈殿の生 成と溶解の様子を観察した。 その結果, 混合ガスを吹き込むと溶液が白濁するが, CO2 の分圧(Pco.) が一定の値以上になると白濁した溶液が再び透明になることを確認した。 沈殿の完全溶解に必要なPco2 の値は,次のようにして推定することができる。 CO2 は水に溶けると H2CO3 となるが, この H2CO3 の濃度は Pco, に比例し, その比例定数は 3.2×10-7 mol/(L・Pa) であることが知られている。 また, 溶液中では次の反応が起こる こともわかっている。 H2CO3 ← HCO3 CaCO3(固) Ca2+ + CO32- K4=4.0×10-(mol/L2) ここで, K2, Ks はそれぞれ反応 ②,③の平衡定数, K4はCaCO3 の飽和溶液における陰 陽両イオンのモル濃度の積(K〟= [Ca²+][CO3^-]) であり,一定の温度でそれぞれ一定の 値を示す。これらのことを考慮すると,まず, H2CO3, HCO3", CO3の濃度は Pco. と [H+] を用いてそれぞれ次のように表される。 [H2CO3]=3.2×10-7 × Pco (mol/L) H+ + HCO3- H+ + CO32- [HCO3-]=[A × PCO₂ (23/ [H+] (mol/L) [HA]] 303 Nom K2=5.0×10-7 (mol/L) K3=5.0×10-" (mol/L) Pcoz [CO3^-]=B x 10 (mol/L) [H+]2 (2) (3 6 次に,これらの反応が中性付近の水溶液中で起こっているものとすれば,この水溶液中 に存在するおもな陰イオンはウであり, また陽イオンはエであるから,それぞ れの電荷を考慮すると次の関係式が近似的に成立する。 10 (8) [オ]]=2[カ] mayo 一方、上の実験において CaCO3 が完全に溶解するときは Ki= [Ca²+][CO3^-] の関係 にもとづいて次の式が得られる。 [CO3²] ≤ C (mol/L) OH したがって, これらの式から Pco の値を求めると, PcoD (Pa) となる。 なお、

質問です。 (5)のⅡ群のところは答えがクなのですが、私はカだと思ってしまいました、、、 また、(6)については、答えはイなのですが、ウだと思ってしまいました。 どうしてこれらの答えになるのかがよく分からなくて、、 教えて下さい〜!!! 宜しくお願いします。

3 次の英文は, 中学生の花子 (Hanako) が行ったスピーチである。 これを読んで、 問い (1) ~ (9) に答えよ。 (24,5) There are some people cleaning streets in my town every morning. Also, there are some *crows looking for something in the trash. Many kinds of trash are *scattered around the *dump by them. That is a problem of trash and crows. Many people don't want to *fight with crows, but they want to solve the problem. IA J There is one way to solve the problem. I often see yellow plastic bags for trash. I heard that crows 2[(7) put (1) see (5) the yellow / (I) in / () cannot / () the things] bags. If crows think that there isn't any trash in them, they will go to another place, and we don't have to fight with crows. [B] *However, many crows still come to dumps in my town. They learn quickly and understand well, and they know where to find something for their lives. So, they come back to look for it in trash if they think they can do that easily. What are they trying to find in our trash? If I can answer this question, I may find a better way to solve the problem of trash and crows. So, I started learning about crows. My uncle is studying about crows. He often watches crows in some places and tries to understand their lives. He 3 (tell) me about it last week. They get up very early in the morning and usually start looking for their food in the trash of some restaurants or food shops. In such trash, crows can find their favorite food like *French fries or *mayonnaise. My uncle said that they like *oily food. I thought it's interesting because I like the same food. [ C] Also, they want to find something for making their houses. For example, they need *soft things like dog hair or "cotton because they want to put their eggs on such things. I was surprised to learn that crows find these things very well. There are some better ideas to solve the problem of trash and crows, my uncle said. First, people should put a big *net over the trash. When there is a net, it is difficult for crows to scatter trash around a dump. Heavy nets with small mesh are better. Second, when people put their trash in the dump, they should be careful about the time. Usually, the trash is 4(collect) in the morning. Crows may come and scatter it before that if you put the trash in the dump the previous night. 【D If it is difficult for crows to get their food in our town, they will move to another place. 5My uncle knows what we can do to solve the problem of trash and crows because he always tries to understand them. I think he can see the problem from the side of the crows. 6 We don't want to fight with crows, but ? I've heard that the crows sometimes hit people. Do they want to fight with us? That may not be true. My uncle said that the crows are trying different ways to say, "Don't come around our house!" They want to protect their children when someone comes around their house. Crows are large birds and they can fly, so they look strong. However, they are afraid if someone is near them and they don't usually want to fight with us. So, they don't come around the trash when someone is there. I learned about crows and I understood them better than before. They are just trying very hard to get. things for their lives, and they can find them in our trash easily. So, I don't think they are bad. Scattering trash is a problem to us. However, if I see this problem from the side of the crows, then I will know what I can do to solve it. For example, I will not make much food trash, especially oily food trash, and I can be careful about my way of putting the trash in the dump. There is not an easy way to solve the problem of trash and crows, but now, I know it is important to think about it from the side of the crows. We often think about a problem only from our own side, but if we look at it from another side, we may find a better idea.
