結化(Yuka), リリ 九里(M. Greenの英語の授業で発表を行いました。 発表を聞いたクリー ン先生は, 結花さんの発表についてコメントを書きました。 【 結花さんの発表】 【グリーン先生のコメント を読んで,後の1から8までの各問いに答えなさい。 sog vin 【結花さんの発表】 He Many people in Shiga have worked as volunteers. My grandfather is one of them. worked as a junior high school math teacher for many years and retired five years ago. He has worked as a volunteer at the community center since then. Many children go there to play and study together after school and on weekends. He helps them ( 1 ) every day. He always says that working for other people makes him happy. His words made me interested in volunteer work. bon OR I became a high school student and wanted to try something new. So I did volunteer work at the community center this summer. Now, I will talk about my experiences. I hope my speech will give you a chance to think about volunteer work. During summer vacation, I visited the community center. The community center 【used / many /is/ people/byl living in my city. And the volunteers do a variety of work. My first volunteer work was to take care of elderly people.

I live alone and don't have so many chances to talk to other people, especially to young people like you. So I enjoyed talking with you." I was happy to hear that. In the afternoon, I saw a little foreign girl in the playroom. She was drawing a picture alone. ), I hesitated to talk to her because of my English. Then I remembered Mr. Sato's words. So I went to the girl and said, "Hi, I'm Yuka. You are good at drawing pictures. [4]" She smiled and showed me her picture. Then she said, "I will give this picture to my Japanese friend for her birthday. I want to write 'Happy Birthday!' in Japanese on the picture. Can you teach me how to write it?" I was glad to hear that. I taught her how to write it in hiragana. She practiced many times and looked very happy when she saw the picture after she finally finished 5[write] her message in Japanese.

I do volunteer work, too. I visit the city library every Saturday. I help foreign people there. Some foreign people don't understand Japanese. So I help them borrow books. Do you like to read books?

解き方が分かりません🙇 解説お願いします

r 3 以下の会話文は授業の一場面である。このとき,次の1~4の問いに答えなさい。 先生: 今日は座標平面上の三角形の面積について学び HA T ましょう。その前に,まず, 練習問題です。 右 の図の関数y=1/12x+3のグラフ上に点Aが あります。 点Aのx座標が4のとき, y 座標を 求めてみましょう。 ゆうき:y座標はアです。 先 それでは今日の課題です。 生:そうですね。 【課題】 関数y=1/12/ x+3のグラフ上に次のような2点A, B をとる。このとき △AOBの面積を求めなさい。 ・点Aをグラフ上のx>0の部分にとる。 ・点Bのx座標は点Aのx座標より4大きい。 y-2/+3 ゆうき : それでは,私は点Aのx座標が4のときを考えてみよう。 たとえば,点Aのx座標が1のとき, 点Bのx座標は5です。 また, 0 は原点を表し ています。 IC このとき, 点Bの座標は (8, 7) だから, AOBの面積はイになりました。 しのぶ: 私は点Aのx座標が6のときを考えてみるね。 このとき, 点Bの座標はウだから, AOBの面積は・・・・・・あれ? ゆうきさんと同じ 答えになったよ。 ゆうき : でも、三角形の形がちがうから, たまたま同じ答えになったんじゃないの? 先生:それでは,点Aのx座標をa (a>0) とおいて, AOB の面積は点Aのx座標がど んな値でもイになることを確かめてみましょう。 1 アにあてはまる数を書け。 2 イにはあてはまる数を, ウにはあてはまる座標をそれぞれ書け。 3 会話文中の下線部について,点Aのx座標をa (a>0) とするとき, 点Bのy座標をαを 用いて表せ。ただし,できるだけ簡単な形で表すこと。 4 △ AOB の面積は点Aのx座標がどんな値でもイになることを説明せよ。
