"It was really noisy outside my apartment last night so I couldn't any sleep, so I'm still sleepy today.
"It was so noisy I couldn't get to sleep last night, now I'm really sleepy."
"I didn't get much sleep last night because of the noise outside. now I'm really tired."
先生に伝えたいなら一つ目の文を使った方がいいです。フォーマルな場合で騒がしかった物を説明する、パーティーなや 工場音など。ー "My neighbours were having a party lastnight..."
次の二つの文はもっとカジュアルな言い方です。
昨夜は熟睡できなかった - "I couldn't get to sleep last night." "I didn't get much sleep last night." その他のは "I didn't get a good sleep last night."
It was so loud outside my apartment last night, I didn't sleep very soundly at all. I'm still really tired.
この場合、次のような言い方ができますよ。
ーIt was so loud outside my apartment last night, I didn't sleep very soundly at all. I'm still really tired.
「昨夜、アパートの外がすごくうるさかって全然熟睡できなかった。まだすごく眠い」
to sleep soundly で「熟睡する」
