英語長文演習1学期中間試験 問題用紙 ※解答はすべて、 解答用紙に記入しなさい。 ※解答用紙のみ切り離して提出する。 1 Read the following essay and answer the questions. Most commercial airplanes travel at about 500 to 600 miles per hour. SR-71 Blackbird, which was developed by Lockheed Martin in the 1960s, could fly as fast as 2500 miles per hour. At that speed, you could go from Tokyo to New York in just around three hours. So why does it still take so long for ordinary people to fly? I The to shatter windows One of the biggest problems is that when a plane flies faster than the speed of sound it breaks the sound barrier, causing a sonic boom. This boom is thousands of feet below the plane. II Unfortunately, a lack of fuel efficiency and the high costs of maintenance made it unprofitable. It retired in 2003, just a few years after a major accident. But the dream of supersonic travel never died, and engineers at NASA have finally figured out a way to reduce the sound of a sonic boom to little more than that of a car door shutting. III If all goes well, they will use the data they collect to try to convince regulators to update aviation laws to allow commercial supersonic flight. At least three companies in the US are hoping to advantage of such a change, and they aim to put supersonic planes in the air within the next decade. QUESTIONS: A About the following explanations, put T if it is true, and put F if it is false. Qa. Before realizing the dream of supersonic travel, aviation laws must be changed. b. In 1960s, ordinary people could go from Tokyo to New York in just around three hours. c. Nasa succeeded in cutting down on the sound made by supersonic airplanes. d. The Concorde flew much faster than ordinary commercial airplanes. e. Supersonic airplanes can do damage to houses or buildings when they fly over land. BChoose the right sentence to fill in III a. NASA is hoping to run test flights over land in 2022. b. Military airplanes fly at speeds many times that. c. That's why the Concorde, a supersonic plane that traveled at around 1500 miles per hour, was mostly limited to routes above the ocean. CChoose the appropriate word or phrase to fill in ★ and ☆ . ★ b. so loud c. loud enough a. too loud d. louder a. make b. take C. gain d. share

1 Part 世界の人々は日々の食事に何を食べているのでしょう。 1 Each country has its own staple food, a food which is commonly eaten every day. Staple foods provide carbohydrates, which are our energy source. The major staple foods are rice, wheat, corn and some root vegetables. Rice is eaten mainly in Asia, boiled, steamed, or sometimes made into noodles. Wheat is eaten in Europe and North America. It is usually ground into flour and made into bread or pasta. Corn has been a staple food for people in South America. It is ground and processed into bread, tortillas, or cornflakes. The most common root vegetables are potatoes. They are eaten as a staple food in various areas from South America to Europe. Yams or taro are also eaten widely in Africa, in tropical areas in Asia and in the Pacific. Root vegetables are usually steamed s or boiled, and sometimes mashed before being served. 2 Though we eat staple foods for every meal, they are not necessarily the main part of our diet. * be made into ~ ataple food Lesson 2 Food Culture Phrase Reading Part 2 Part2. 3 Nowadays/about 40 percent of the 今日、世界の約40パーセントの人々が食べ物を people in the world eat food/ 食べます 日常的に手で。 with their hands regularly// Most of them are in Africa, / その内のほとんどの人々はアフリカにいます in the Middle East and in some parts of 中東やアジアの一部に。 Asia.// They believe hands are cleaner than other 彼らは他の器具よりも手の方が清潔だと考えて utensils./ います。 which can be used by someone else. // それは他の誰かに使われたかもしれない。 When you eat with your hands,/ 自分の手で食べるとき, you can feel the texture and temperature 食べ物の感触や温度を感じることができます そしてそれは食べ物をよりおいしく味わわせます。 of food/and it makes food taste better. // In some regions./ 地域によっては, however, / しかし, the left hand is never used / 左手は絶対に使われることはありません because it is considered to be unclean. // なぜならそれは不潔だと考えられているから。 4 Another 30 percent of the people in the 世界の別の30パーセントの人々は、主に東アジ world, /mainly in East Asia, / アの (人々), use chopsticks.// 箸を使います。 They are useful for eating sticky or hot それらはべたべたする食べ物や熱い食べ物を食 food.// べるときに便利です。 They can also cut food into smaller それらはまた食べ物を小さく切り分けたりもで きます。 pieces, / mix ingredients before eating,/ 食べる前に素材をかき混ぜたり、 口の中に食べ物を運んだり。 and carry food into the mouth.// Which do you think is better to use, / hands or chopsticks?// あなたはどちらを使うのがよいと思いますか. 手と箸では。 staple common carbohya source com k root veg bolled steamed North Am pasta ca South Ana stuff a processic p tortillia(s) kat comiaio kirafiki yam (5) Ju taro mashed Imaju necessarly
