皆さんこんにちは。
今年はあまり寒くならずに、なんだかこのまま春へ突入しそうですね。
新型ウィルスの影響で、思いがけず一人で過ごす時間ができたと思います。
読書や勉強に良い機会だと思って、是非有意義に時間を使ってください！

The Space Port of the planet Santana was on a satellite that floated 10,000 meters above sea level, out of the gravitational field of the planet, so that space ships could minimize the damage they would have when landing. A long vacuum tube with an elevator connected the satellite with the ground. The elevator could hold no fewer than 50 people, and took guests to the ground within a few minutes.
