Unit 4　Earthquakes

【单元导航】

Moved by mother’s great love

She had died when the rescuers found her.She was buried by the crushed house.Through gaps of those ruins，we can see her last posture(姿态).Being on her knees，the upper part of the body was prostrate (趴着的) forward，with her hands on the ground to support her body.That was something like an ancient who was kowtowing.

The rescuers confirmed her death by touching her through the gaps of ruins.They shouted at the ruins again and again，knocked the bricks using the crowbar(铁棍)，but no response inside.

Then the rescuing team went to next building，suddenly the leader ran back，calling “come here”.He came to the body，stretched his hands under the woman，feeling and touching，then shouted loudly “there is someone，a baby，still living”.

Through some efforts，rescuers cleaned up the ruins carefully which blocked her.Under her body lay her baby，who was wrapped in a small red quilt with yellow flowers scattered in red.He was about 3 or 4 months’ old.Since well protected by mother’s body，he was totally safe.He was sleeping on both ears when the rescuer carried him out，and his lovely and peaceful face warmed everyone around him.The doctor along with the rescuing team unfastened the quilt to check if the baby was all right，and he found there was a mobile phone filled in the quilt.The doctor looked at the screen subliminally，a written message was already there: “My dear baby，if you could live，don’t forget how much I love you”.As a doctor，he experienced too much of parting forever;but at this moment，he wept.The mobile was passed，every person who saw this message shaded tears.
