For most Americans, \"morning\" usually means any time after getting out of bed and before noon. In formal English, \"in the am\" is any time that would be written with \"am\" after the number (12:01 am to 11:59 am). But 12:30 am is usually described as \"late night,\" not \"early morning.\" Here are approximate clock times for the times of day.
对于大多数美国人来说，morning指的是起床后到中午前的任何时间。在正式英语中，in the am是指在数字后写上am的任何时间（12：01 am至11：59 am）。但是12：30 am通常称作\"深夜\"，而不是\"凌晨\"。下面是一天中的不同时间所对应的大致的钟点。
noon 12:00 pm Let's meet at noon. noontime (around noon) 11:00 am to 2:00 pm Did you see him at noontime? afternoon 1:00 pm to 6:00 pm John practices in the afternoon.
evening 6:00 pm to 8:00 pm They eat dinner in the evening. night 8:00 pm to midnight Bob watches TV at night. late night midnight (12:00 am) to 3:00 am Bob doesn't watch late night TV.
