37. What time did you go to bed last night? Is this when you usually go to bed? (附答案)

1. Last night, I didn't go to bed until 1 am, but this was an exception. Normally, I would go to bed around 11 or so. 

2. I went to bed right around 11:30 which is the usual time for me. I don't like staying up much later or I will be grumpy the next day.
