Let’s order!」 2. 途中で結論を出すとき 友達の正面玄関の前に立って、ベルを鳴らしましたが、誰も来なかった場合: 「He must not be home.」⭕️ 「Seems/looks like he’s not home.」⭕️ 「He must be out」⭕️ 「He’s probably out.」⭕️ 3. 同情するとき 友達は新入社員になりました。だけど、仕事場で責任が多くて新しい環境に順応するのは難しいそうです。仕事の後、居酒屋で話してます。 新入社員:「...and then after lunch I was asked to prepare a presentation for next week! That’s on top of (in addition to) the other two projects I have!」 あなた:「That sounds rough. It must be difficult to make any progress!」 メモ: 3番の風で「嘸大変でしょう！」っていう言葉は場合によって「That must be difficult (for him/her)!」として訳すことができると思います。 じゃみんな、この「に違いない」の「must be」をこれから実際に使っていきましょう👍 ## Learning Language **Japanese** ## Topics #431 ## Metadata -
