1
1. A mysterious visitor.
2
In October 2017, astronomers in Hawaii saw something surprising.
3
A strange object was moving through the solar system.
4
They had seen many asteroids before, but this was something different.
5
It was long and thin, like a cucumber.
6
The object's speed and direction also showed something surprising.
7
This was an interstellar object, the first ever seen.
8
B. The object was named Umuamua, Hawaiian for visitor from afar.
9
Nobody is sure exactly what it is.
10
The simplest idea is that Umuamua is a strangely shaped piece of rock.
11
Perhaps it was knocked out of a far-off star system.
12
However, astronomers saw that its speed increased after passing the sun.
13
Some scientists therefore suggest a different theory.
14
C. Umuamua could be a piece of alien technology," says Professor Abraham Loeb from Harvard University.
15
Loeb believes this could explain the object's long, thin shape and also its change in speed.
16
Maybe Oumuamua was a spaceship that came to explore our solar system.
17
All possibilities should be considered, says Loeb.
18
De Oumuamua can no longer be seen from Earth, but astronomers continue to study the information they got from it.
19
It is still not clear if the object was a large rock or something else altogether.
20
Umamua will likely be a mystery for many years to come,

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
