直到凌晨英语

until 2 a.m.祝你学习进步，更上一层楼！(*^__^*) 有不会的可以再问我:）

Lsat night I didn't fall sleep until 3 o'clock in the morning.

Untill 2 o'clock early this morning.

英文原文：Yesterday I didn't fall asleep until three in the morning.英式音标：[ˈjestədeɪ; -dɪ] [aɪ] [ˈdɪdnt] [fɔl] [əˈslip] [ənˈtɪl] [θri] [ɪn] [ðə] [ˈmɔrnɪŋ] .

I didn't finish my homework until 1 o'clock.

dawn, midnight, morning 这些都差不多不过如果比方说凌晨2点的话，用的还是 2 o'clock AM
