Everyone was surprised that Mike won the game.
Is this sentence correct?
Can I omit “that” in this sentence?
I’d appreciate it if you would answer my question.
Everyone was surprised that Mike won the game. が正しい文章です。
Everyone was surprised/shocked when Mike won the game もいいと思います。
that もしくは when がなくても文章が成り立ちますが、that や whenが入ると文の運び方がより良いと個人的に思います。
"マイクがそのゲームに勝ってみんな驚いた"
- Everyone was surprised that Mike won the game.
- Mike won the game and everyone was surprised. （順番を逆にする）
You can omit "that" from the sentence
- Everyone was surprised Mike won the game.
