example_Japanese = '''こんにちは！

みなさん、私たちのプレゼンテーションにワクワクしていますか？
おなかがペコペコではありませんか？
では、ニコニコして、聞いてください！

今日のプレゼンテーションのテーマはオノマトペのくりかえすことばです。

そのようなことばをみなさん何か知っていますか？

日本語はくりかえすことばを毎日つかいます。気持ちやようすをよくひょうげんできるし、わかりやすいし、いんしょうにのこり やすいからです。たとえば、「ぴかぴか」と聞いたら、どうおもいますか？どんなイメージですか？やっぱりきれいやでんきのひかりですね。'''

example_English = '''Hello!

Are you all excited about our presentation?
Aren't you hungry?
So, smile and listen!

The theme of today's presentation is onomatopoeic repetition.

Do you know any such words?

In Japanese, we use repeated words every day. It's easy to understand, easy to understand, and easy to follow. For example, what do you think when you hear the word "pikapika"? What kind of image do you have? After all, it is a beautiful and electric light.'''
