Ten-year-old
Sami loved to visit his grandfather's house. The house was near the beautiful
blue sea. At the seaside stood thick and tall palm trees with green coconuts
hanging from them. When the coconuts fell down, Sami would break them open and
drink the coconut water. Sami liked to play under the trees. It was always
great fun to spend the holidays at Grandpa's place.
This
winter vacation, Sami was surprised when he came to his grandfather's village.
There were hardly any trees left. He saw houses built near the sea. People had
cut down many palm trees and there was hardly any greenery left.
Grandpa's
house was different. He never allowed his trees to be cut. He hugged each palm
tree in his courtyard. He also named the two big trees near the front door--one
was Petu, and the other Betu. He had planted them with his own hands and today
they had become large, massive trees with thick trunks. They were tall and
green and gave the sweetest, juiciest coconuts.
One
night, Sami was awakened by a strange sound. He could not sleep. He tossed (辗转) and turned in bed.
Suddenly,
the ground shook as if the earth was splitting. He sat up straight and then ran
to Grandpa. He clung（附着）to his grandpa
tightly. Grandpa cried out, "It's an earthquake! It's an earthquake!"
They ran outside the house. They thought that would be safe.
Suddenly,
there was a loud sound; the earth was not splitting but the sea was roaring.
People were shouting, screaming and crying, "The sea is rising! The sea is
rising." The villagers started running away from the beach.
Sami
watched dumbstruck (呆若木鸡).
The
waves were rising higher and higher. Sami thought, "How big the waves
are!" He went into the house again and saw water coming in from all sides.
He was scared.
Sami
remembered his mother telling him long ago," You must always get out of
the house if the floods come too near." He ran outside the house with
Grandpa. But the water came surging (汹涌)
in.
Waves
about twelve meters high came rushing in, drowning everything. Water was all
around and everywhere.
Paragraph 1：
Grandpa
held Sami's hand tightly but a huge wave separated them.
Paragraph 2：
"Sami,
Sami!" Grandpa cried. "Don't be scared, little one, come to me,
quickly."
