- 顔が良ければ、 性格が悪くてもいいと言うのは、 まちがいです。
It's a mistake to believe that "a bad personality is no problem, as long as the person is good-looking". If you can see that the "と言うのは" represents "quote marks" (kind of) then this one becomes much easier, right?
- 彼女はおづるのはうまいが、ごはんを作るのは下手だ。
She's good at dancing but no good at cooking.
- この意味を調べたいんですが、どのじしょで調べたらいいですか
I want to work out what this means. What dictionary should I use?
- しまった!! ともだちに明日はクラスがないと言うのを忘れた!
Damn!! I forgot to tell my friend there's no class tomorrow!
(EDIT: Sorry I just did these quickly because I'm bored, and I didn't check and see until later that you guys had mostly done them already. Anyway I will just leave the post as an alternative version, but don't take that to mean "I'm right and you're wrong" since you guys' versions were fine)
