| 汶川地震，全国很多地方都有震感。请你根据下面方框中所给词语，模仿Sandra对当时经历的描述，把Benny的描述补充完整。字数60-80。 Sandra: I was almost asleep when I felt the bed rocking. Suddenly I noticed our blinds (百页窗) moving. So I quickly looked around to see what was happening. I found my ceiling fan was moving although I had turned it off a moment ago. I quickly woke up my children and we left the building as quickly as possible.
