I'd like to speak to you in private.
あなたと内密に話したいのですが
I'd like to take this chance to say that I'm very sorry.
この機会に深くおわびします
I'd offer you some of this, only I'm really hungry.
これを分けてやりたいんだが，あいにく腹ぺこでね
I'd prefer it if you didn't bother me.
じゃましないでいただけるとありがたいのですが
I'd prefer to stay in a house than in a hotel.
ホテルより家にいるほうがよい
I'd rather die than do that again.
もう一度それをするなら死んだ方がましだ
I'd rather [sooner] die than spend my days in a place like this.
こんな所で暮らすなら死んだほうがましだ
I'd rather go somewhere else.
別の場所に行く方がよい
I'd rather not do a thing at all than do it badly.
へたにやるくらいならやりたくない
I'd say it's too late.
まず手遅れでしょうね
