2018年4月5日「モバイル英語学習」第448号(英語のエッセイ): The Kangaroo Route

Notes:

—————————-
How far can you fly on a passenger plane? The new flight from Perth, Australia, to London, England, is one of the longest passenger flights in the world. It is also the first regular flight from Australia to Europe. Australia has a close relationship with Britain, and Qantas, the Australian airline, started flying the Kangaroo Route to London in 1947. At that time, it took four days and nine stops. Now, the direct 14,498 kilometer flight takes just 17 hours. This is possible because Qantas has a new jet, the Boeing 787. It is lighter than older jets and uses 20% less fuel. (by Prof. Douglas Jarrell)

2018年1月31日「モバイル英語学習」第440号(英語のエッセイ): In the Shadow of the Earth

Notes:
lunar eclipse 月食;
————————-
Get ready to watch a great performance in the sky. There will be a lunar eclipse tonight, and the moon will get dark for several hours. How does this happen? The earth moves between the sun and the moon, and the earth’s shadow falls on the moon. The moon loses its bright yellow color and becomes a dark red. Tonight the moon will start to change color after 8:50 p.m, and at 10:30 it will be at its darkest. It will get lighter again, and just after midnight the eclipse will be over. If the weather is good in your area, you will be able to see it in the southeast sky. (by Prof. Douglas Jarrell)

2017年12月19日「モバイル英語学習」第433号(英語のエッセイ): Space and High School Students

Notes:
astronaut 宇宙飛行士;

wire top 針金ゴマ
————————–
On Sunday, Kanai Norishige became the 12th Japanese astronaut to go up into space. He went up in a Soyuz rocket from Kazakhstan. Two other astronauts joined him, Anton Shkaplerov of Russia and Scott Tingle of the U.S.A. They are all heading to the International Space Station and will get there sometime today. This time, Kanai will do two experiments that were designed by high school students. One is to see how a paper spring works in almost zero gravity. The other is to see how a wire top spins. I hope they will take a video and show us what happens later! (by Prof. Douglas Jarrell)

2017年12月7日「モバイル英語学習」第431号(英語のエッセイ): Fly Faster

Japan Airlines thinks we will want to fly faster in the future, so it is putting its money on a supersonic airplane. That’s an airplane that flies faster than the speed of sound. There used to be supersonic airplanes. France and Britain produced the Concorde, a beautifully designed airplane with a nose that pointed down. It was fast but very expensive. It could fly over the ocean, but the noise over land was too loud. The Concorde stopped flying in 2003. Now JAL is investing in a company called Boom which will build new planes. People will again be able to fly long distances in half the time. (by Prof. Douglas Jarrell)
