　My best memory from junior high school is [the] field day.We were [doing a]

cheering dance and sang [the] school song. All things remain in the impression. [I

rember only vaguely] But [in particular one event I remember] is [a] cheering dance.

We danced [to remember] for life. When [we] finished dancing, [we were] filled with

satisfaction. But result [was] [the] 2nd prize. [Really we were sad (that we did

not win the first prize)] ・・・but there was no regret at all. I learned from this

school festival a lot. For example, [the] spirit of [helping each other]. I want to

make the best use of learning from this experience in the future.

　１等になれなくて残念だったが悔いはない、の両方を regret 系の言葉で表現すると聞く方（読む方）が混乱すると思いましたので、前者を sad、後者を regret　と分けました。

　なかなかいいじゃないですか。
