Many years ago, an earthquake happened suddenly. A lot of buildings

collapsed(倒塌)。 It killed over 100,000 people in a few minutes. Shortly

after the earthquake, a father rushed to the school where his son studied

only to find the building had fallen down. He remembered his promise to

his son:“No matter what happens, I’ll always be there for you!”

The tearful father began to dig to look for his son. Some parents

felt hopeless and tried to pull him off. But he asked,“Are you going

to help me now?”And then he kept on digging. The fireman came.

They tried to pull off and said,“Danger! Leave here!” But the

father who loved his son deeply,asked,“Are you going to help me now?”

The policeman came up and said,“It’s over.Leave here!We’ll do it.”

Still he asked again and again,“Are you going to help me now?”

He went on alone because he needed to know,“Is my boy alive or

is he dead?” He dug for 8 hours…12 hours…24hours…36hours…then, in the 38th hours, he pulled back a large stone And heard his son’s voice. He cried,“Tom!”He heard back,“Dad? It’s me, Dad! I told other kids you’d save me. I believe you would keep your promise.”“Get out, boy!”“No dad! Let the other kids out first. Because I know you’ll get me out!
