It was a terrible day for Mr. and Mrs. Lin. The two were on holiday in a mountain. They were taking a walk in the early afternoon when suddenly the ground started to shake. In just two minutes, everything was different！They were in the middle of a very strong earthquake（地震）！
The Lins tried to find some other people first. One by one, they found 23 other people. Many were visitors, young and old. Soon it was dark and it started to rain heavily. Some cried and some lost hope.
At that point, Mr. Lin decided to do something. He said," The roads are too dangerous. We can't go down the mountain until tomorrow. We must stay here tonight. "Then Mr. Lin and a few young men went back to look for food. They found some, but not enough for everyone. The young people gave theirs to the older ones.
After that, Mr. Lin divided（分开）the people into five groups. He also brought all the mobile phones and made sure each group had one. They used them as flashlights（手电筒）. The light in the dark rainy night made everyone feel safe.
Early the next morning, the groups started to go down the mountain. It was difficult, ____. After twelve hours' walking, they finally got out. By then, it was 30 hours after the earthquake. Everyone was tired but they felt lucky because they were part of a special team. This special team gave them hope for life.
