I like listening to podcast about Japan and world's history named 'Coten Radio'.
Recently I am listening to its up-to-date series about history of technology.
Because I am interested in not only history but also technology, I am really curious about how human beings have been developing their own civilization with technology.
The podcast series often has a lot of difficult contents but I want to tell them to my children with a comprehensive explanation.

修正ポイントの解説

① "podcast about Japan and world's history" → "a podcast called Coten Radio, which covers..."
「named」より「called」、そして「which covers...」で補足説明を自然に追加できます。

② "up-to-date series" → "latest series"
「最新のシリーズ」は “latest series” の方がポッドキャストや TV シリーズの文脈にマッチ。

③ "how human beings have been developing their own civilization with technology"
→ "how human beings have developed civilization through technological advancements"
時制を過去完了形ベースにして、「through technological advancements」とすると洗練された印象になります。

④ "difficult contents" → "complex topics"
“contents” は情報の中身そのものを指し、可算名詞ではありません。ここでは「話の内容＝ topics」が適切。

⑤ "comprehensive explanation" → "in a way that's easy to understand"
「包括的な説明」より「わかりやすい説明」の方が、子ども向けという文脈にマッチ。

学習メモ

• 「内容が難しいけど伝えたい」時は、"in a way that's easy to understand" という表現が便利
• “I enjoy ~ing” は好みを自然に伝える定番フレーズ
