我们必须在晚上九点前上床，早上八点起床。

We had to be in bed by 9:00 pm and up at 8:00 am.

在家的时候，我们上床时要脱掉衣服；在这儿，睡觉前要穿得更多——包括戴上毛线帽子和手套。

Back home, we undress at bedtime; here, we put on more clothes—including woolly hats and gloves—before going to sleep.

每当上床睡觉前我总是要确保房间的门和窗关的安不安全，关没关严实。

Before going to bed, I would make sure the door and the Windows of my room were securely and tightly shut.
