同学你好~
不客气的。

A plane crashed in the mountains, but the only passengers, a
young woman and her two baby daughters, were not hurt. It was
midwinter and extremely cold, so the woman put the children in a
case, covered them with clothes and kept close to them all night.
When she heard planes early next morning, she stamped out SOS in
the snow. This was seen by a pilot, who sent a radio message, and
they were soon rescued by a helicopter.
