At 9:00 a.m., they find that most of the babies are already awake and hungry. 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. You should have to shake her awake.注意，awake不用于名词前，因此用作定语时要后置。 e.g. She was the last person awake.另外，awake不与very搭配使用，表示“完全醒来；十分清醒”用fully awake, wide awake。e.g. He was wide awake by the time we reached my flat. 等我们到达我的住所时，他已经完全醒过来了。5. they run over to them with excitement and some of the young pandas even walk into their friends and fall over!run over 跑上前去 over adv.穿越；从的一边到另一边e.g. She ran over to say hello, but I didnt recognize her.她跑过来打招呼，但我没有认出她来。walk into （走路时意外）撞上e.g. As he was thinking too deeply and not playing attention to where he was going, he walked straight into a tree.由于他陷入深思，没有注意看路，径直撞到了一棵树上。fall over 摔倒；倒下e.g. Dont run too fast, or you might fall over. 别跑的太快，要不你会摔跤的。fall over something 被某物绊倒e.g. Tommy fell over the dog and broke his front teeth.Tommy被那只狗绊了一跤，磕断了门牙。6.
