There are lots of ways, like going to museums or reading textbooks in school and asking their teachers, but for me, the best way is to speak to old people. Obviously, we can only go back a certain amount of time this way but, by talking to the people that were actually there, children can get a much deeper sense of what it was like. Watching films and TV series gives us a general idea of what a period in time was like but it's mostly made up and, therefore, not an accurate representation of history, so for more recent history, I prefer to ask the people that were there.
いろいろな方法がありますが、私にとって最良の方法は高齢者と話すことです。物語を聞くことで、その時代の本当の姿をより深く理解できます。映画やテレビシリーズはその時代の一般的なイメージを提供しますが、ほとんどが創作であり、歴史の正確な表現ではないため、より最近の歴史については直接当時の人に尋ねることを好みます。
