4.At9:
00a.m.,theyfindthatmostofthebabiesarealreadyawakeandhungry.
英语中，awake常用于be,stay,keep,lie之后，作表语；但也可与shake等动词搭配，表示“某人摇醒他人”等。
e.g.Youshouldhavetoshakeherawake.
注意，awake不用于名词前，因此用作定语时要后置。
e.g.Shewasthelastpersonawake.
另外，awake不与very搭配使用，表示“完全醒来；十分清醒”用fullyawake,wide
awake。
e.g.Hewaswideawakebythetimewereachedmyflat.
等我们到达我的住所时，他已经完全醒过来了。
