I like summer the best.
Because i like swimming very much.
And we can enjoy eating icecream.
But it is very hot.

これでどうですか～？
ちょっとおかしなところもあるかもしれないです😭😭
おかしかったら教えてください！

I like spring the best.
Because I like cherry brossoms.
It is beautiful and pretty.
Also, I can make a lot of new friends in Spring.
I feel like happy every spring.

なるべく簡単な単語を使いましたが、文章は少し手直しし、あなたに合わせた方がいいかもしれません。
