英語 中学生 2年弱前 いの答えと考え方を教えてください。 5 10 15 20 25 30 The Olympics were held in Tokyo in 1964. A few years ago before the Olympics, Japan had a big problem. It was a problem of communication. Many foreign people didn't visit Japan, and we had only, Japanese signs. For example, words like "i" or "" were on toilet doors. These signs were not understood by many foreign people. Japanese people at that time needed to make signs in many different languages for foreign people. But when they put many words on one sign, the "letters became too small. They could not easily read the sign. They had to think of ) signs for foreign people. Mr. Masaru Katsumi, a leader of a design team for the Olympics, had a great idea. everyone /to/ was easy / thought / understand he forit pictures. He wanted to make picture signs. These signs are called *pictograms and are used in many places now. Picture 1 Picture 2 Picture 3 Look at these pictures. Picture 1 shows a shower. Picture 2, shows a toilet. Picture 3 shows a restaurant. Foreign people can easily understand what each picture shows. They had to make pictograms which everyone could understand without any trouble. When they started to make them, one of the pictograms was a shower. Many Japanese people didn't know about showers at that time and didn't have one at home. One of the designers didn't even know the word "shower." One officer had to explain how to use it with a photo of a shower. The designer made the pictograms through the officer's words. With a lot of trouble and hard work, twelve designers needed three months and made pictograms for the Olympics. When the last pictogram was finished, Mr. Katsumi said to all the designers, "You did a great job, but this work is not for us. We did it for all Japanese people. Please write your names on this paper." The paper said that they'd like to give up the *copyright to the pictograms. They wrote their names on the paper. They gave up the copyright. One of the designers said, "Mr. Katsumi hopes that many people in many places will use the pictograms in the future. Money from the copyright is not important to Mr. Katsumi. He is proud that he is one of the members who worked for the Tokyo Olympics." In 2020, we are going to have the Olympics in Tokyo. Our life will change a lot. What kinds of new signs or pictograms will we see around us? (E) letter pictogram ピクトグラム(絵文字) designer www. デザイナー officer 役人 copyright 著作権 回答募集中 回答数: 0

英語 高校生 2年弱前 赤線を引いているところがよくわからないのですが、まず、 1、母と議論するのは難しかったとありますが、何についての議論か 2、最後の分の「彼女は首に巻いた〜合図であった」は何を意味しているのでしょうか できれば要約をお願いしたいです🙇 14 第6問 次の文章を読み、下の問いに答えよ。 標準解答時間 9分 depressed. It was not the exam that made her feel that Christine came out of her last examination, feeling way, but the fact that it was the last one; it meant the end of the school year. She dropped in at the coffee 5 as usual, then went home early because there didn't 10 seem to be anything else to do. shop "Is that you, dear?" her mother called from the living room. She must have heard the front door close. Christine went in and sat on the sofa. "How was your exam, dear?" her mother asked. "Fine," said Christine flatly. It had been fine; she had passed. She was not a brilliant student, she knew, but she was hard-working. Her professors always wrote things like "A serious attempt" and "Well thought out but 15 perhaps lacking in energy" on her term papers; they gave her Bs, the occasional B*. She was taking Political Science and Economics, and hoped to get a job with the government after she graduated; with her father's connections she had a good chance. 20 "That's nice." Christine felt, bitterly, that her mother had only a vague idea of what an exam was. She was arranging roses in a vase; she had rubber gloves on to protect her hands as she always did when engaged in what she 25 called 'housework.' As far as Christine could tell, her housework consisted of arranging flowers in vases. Sometimes she cooked elegantly, but she thought of it as a hobby. It was hard, anyway, to argue with her mother. She was so easily upset that it was better to avoid 30 arguing with her. 回答募集中 回答数: 0
