この問題は、高分子化合物を覚えて解くという感じですか? 芳香族のように自分で構造を作ることは不可能ですか?

KADA N 生しな は、 こに 12 高分子化合物A ~Hに関するつぎの記述アーカを読み、 下の問に答えよ。ただ し、各元素の原子量は, H=1,C=12, N=14,0=16とする。 ア. AとBはいずれもエチレンの付加重合で得られ, Aは触媒を用いて低圧,60 ℃前後で, Bは高圧, 200℃前後で合成される。 イ.Cはテレフタル酸ジクロリドとかフェニレンジアミン(カージアミノベンゼン) の縮合重合で得られ,Dはアジピン酸とヘキサメチレンジアミンの縮合重合で得 られる。 ウ.EはE-カプロラクタムの開環重合で得られる。 エ.Fは無水フタル酸とグリセリンから得られる樹脂であり, 自動車用の塗料など に用いられる。 オ.Gはポリビニルアルコールをホルムアルデヒドでアセタール化することによっ て得られ, 合成繊維などとして用いられる。 カ. 天然に樹液から得られるHはイソプレンの付加重合体であり,炭素間の二重結 合(C=C) の部分がすべてトランス形の構造である。 問 つぎの記述のうち, 誤っているものはどれか。 AはBと比べて結晶部分が少なく, 透明で軟らかく, ポリ袋などに用いられ LBだけの話 る。 2.

英語 ( 70分) 1 次の文章を読んで 1~7の問いに英語で答えなさい。 It's Christmas Eve, December 24, 1914. The night is clear and cold/ Moonlight illuminates the snow/covered land separating the British and German trenches outside a small town in northern France. British military command feeling nervous sends a message to the front lines: it is thought possible the enemy may attack during Christmas or New Year. Extra caution will be maintained during this period. The military command has no idea what's really about to happen. Around seven for eight in the evening/ British soldier Albert Moren blinks in disbelief What's that on the other side? Lights flicker on./ one by one. Lanterns. he sees, and torches, and... Christmas trees? /"Stille Nacht, That's when he hears it - soldiers singing in German/" heilige Nacht." Never before had the Christmas music sounded so beautiful. I shall never forget it," Moren says later. It was one of the highlights of my life. Then, in response, the British soldiers start singing The First Noel." The Germans applaud, and counter by singing "O Tannenbaum." They go back-and-forth for a while, until finally the two enemy camps sing "O Come, All Ye Faithful" in Latin, together. "This was really a most extraordinary thing." soldier Graham Williams later recalled, "two nations both singing the same Christmas music in the middle of a war." Events just north of a small town in western Belgium go further still. From the enemy trenches, Corporal John Ferguson hears Someone call out, asking if they want some tobacco. "Come towards the light," shouts the German. So Ferguson walks out into no-man's land into the field between both armies. "We were soon speaking as if we had known each other for years." he later wrote. "What a sight little groups of Germans and British talking together almost as far as the eye can seel Out of the darkness we could hear laughter and see lighted matches.... Here we were laughing and chatting to men who only a few hours before we were trying to kill!" The next morning. Christmas Day, the bravest of the soldiers again climb out of the trenches. Walking past the barbed wire, they go over to shake hands with the enemy. Then they wave "come on!" to those who'd stayed behind. "We all cheered." remembered soldier Leslie Washington of the Queen's Westminster Rifles. "and then we all came out together like a football crowd." (A Gifts are exchanged. The British offer chocolate, tea and cakes: and the Germans share cigars, sauerkraut and schnapps. They make jokes and take group photographs as though it's a big./happy reunion/ More than one game of football is played./using helmets for goal posts. One match goes 3-2 to the Germans, another goes to the British, 4-1. In northern France/the opposing sides hold a joint burial service. "The Germans formed up on one side." Lieutenant Arthur Pelham- Burn later wrote./"the English on the other, the military officers standing in front, helmets off, heads bowed in respect. As their friends are laid to rest friends killed by enemy bullets - they sing in English "The Lord is My Shepherd" and the same song in German mein Hirt" their voices in unison. "Der Herr That evening, there are Christmas dinner parties up and down the lines. One English soldier finds himself invited into the German held zone to a wine cellar, where he and a soldier from southern Germany pop open a bottle of 1909 French champagne. The men exchange
