     When we talk about a bad man, we like to call him a “wolf”. But is it really true that the wolf stands for
devil and ugliness？
     Have you read the book “The Wolf Totem” by a famous writer Jiang Rong, which tells the story of the
relationship between wolves and human beings? Have you ever_1_the wolves' world? If you had, you
would    2   the wolves.
     In the book, wolves are heroes on the large grassland. They know more about   3   than humans. They
can attack lambs (羔羊) without disturbing their mothers. They also know how to  4   full use of the shape
of land to  5   sheep. I believe that if wolves were humans, they would be   6   experts good at fighting.
     The wolf is a kind of special creature that can deeply understand    7  . Each wolf serves its group with
its heart and soul. A   8   wolf has little power, but a pack of wolves  9   nothing. All the wolves obey the
rules.    10  they are defeated, they run away together. It is their teamwork  11  makes wolves powerful.
     The wolves also have great self-respect and won't   12   to anyone. The writer, who wrote the book
“The Wolf Totem”, 13   stole a one-month-old baby wolf and raised it very carefully. To his 14  , he found
the little wolf still wanted to go back with   15   wolves. He bit through the iron chain that limited him. The
wolf was 16   and he never gave in, fighting   17   his death. The little wolf died as a glorious fighter.
     I was shocked by this kind of  18   : wolves are one of the most respected creatures on earth. I want
everyone to look at wolves in a   19   way. They are our teachers. They show us how to survive and   20  
in this not simple and dangerous world. Please honor the wolves, please honor all these heroes of nature!
