爬楼梯到山顶
They had to be small enough for people on the top floors to climb stairs. People could not be expected to climb a mountain at the end of their journey to work, or home.───那就是楼房必须能让顶层的居民上下方便，人们下班回家后肯定不想像爬山那样去爬楼梯。
There was no turbo lift, and they had to climb the stairs to the top floor.───楼内没有涡轮电梯，他们只能走楼梯到最高一层。
climb the stairs───爬楼梯
all the same to me───对我来说都一样
climb the walls───非常烦恼；焦躁不安
