M: Linda! Didn't I tell you to turn off the TV and go to bed?
L: I don't see why I can't stay up. It's only ten.
M: I'm your mother and mother says to go to bed. That's why.
L: That doesn't make sense.

M: 琳达！我没告诉你要关掉电视上床睡觉吗？
L: 我不懂为什么我不能待晚一点。现在才十点。
M: 我是你妈，我说上床睡觉。懂了吧。
L: 这没道理嘛。

重点解说：

★ turn off = switch off「关掉」如： turn on; switch on「打开」

★ I don't see why ~ 或I can't see why ~ 「我不懂为什么~」的句式用于质问理由，带有无法信服的味道，也可以用understand来代替see。I don't see why I should apologize to him.「我不懂为什么我必须跟他陪罪。」

★ make sense「有道理，讲得通」如： 众人据以作出明智判断的「常理」英文称为common sense，众人皆知的「常识」英文称为common knowledge。
