I'm afraid that I can't get up. 这是什么句型? 请教英文知识I'm afraid that I can't get up我恐怕站不起来了I'm afraid I can I'm afraid that I can't. i'm afraid that i can't I'm afraid I can't get there before 9 o'clock.That's OK.Ther I think that I've hurt my back.I'm afraid that I can't get u I'm afraid I can't hear you.这句话为什么afraid后不加that? I'm afraid that he can't ...能不能去掉“that”? 关于get的用法,急Sarah,hurry up .i'm afraid you can't have time to afraid,i,that,can,get,am,i,not,up 怎么连接 I'm afraid that I can't.这句话为什么有两个主语?该 I'm afraid that I can't.为什么afraid后面没有跟of
