听力原文： When you take a walk in any of the cities in the West, you often see a lot of people walking dogs. It is still true that a dog is the most useful and faithful animal in the world, but the reasons why people keep a dog have changed. In the old days people used to train dogs to protect themselves against attacks by other beasts. And later they came to realize that a dog was not only useful for protection but willing to obey his master. For example, when people used dogs for hunting, the dogs would not eat what was caught without permission. But now people in the city need not protect themselves against attacks of animals. Why do they keep dogs, then? Some people keep dogs to protect themselves from robbery. But the most important reason is for companionship. For a child, a dog is his best friend when he has no friends to play with. For young couples, a dog is their child when they have no children. For old couples, a dog is also their child when their real children have grown up. So the main reason why people keep dogs has changed from protection to friendship.

A．For protection against other animals.

B．For protection against other dogs.

C．Just for fun.

D．For the purpose of guarding the house.

Man of Few Words

Everyone chases success, but not all of us want to be famous.

South African writer John Maxwell Coetzee is_______（51） for keeping himself to himself. When the 63-year-old was named the 2003 Nobel Prize winner for literature earlier this month, reporters were warned that they would find him "particularly difficult to_______（52）".

Coetzee lives in Australia but spends part of the year teaching at the University of Chicago. He seemed_______（53） by the news that he won the US$1.3 million prize. "It came as a complete surprise. I wasn't even aware they were due to make the announcement," he said.

His_______（54） of privacy led to doubts as to whether Coetzee will attend the prize-giving in Stockholm, Sweden, on December 10.

But despite being described as_______（55） to track down, the critics agree that his writing is easy to get to know.

Born in Cape Town, South Africa, to an English-speaking family, Coetzee_______（56） his breakthrough in 1980 with the novel "Waiting for the Barbarians （野蛮）". He_______（57） his place among the world's leading writers with two Booker prize victories, Britain's highest honour for novels. He first_______（58） in 1983 for the "Life and Times of Michael K", and his second title came in 1999 for "Disgrace".

A major theme in his work is South Africa's former apartheid （种族隔离） system, which divided whites from blacks._______（59） with the problems of violence, crime and racial division that still exist in the country, his books have enabled ordinary people to understand apartheid_______（60） within.

"I have always been more interested in the past than the future," he said in a rare interview. "The past_______（61） its shadow over the present. I hope I have made one or two people think_______（62） about whether they want to forget the past completely."

In fact this purity in his writing seems to be_______（63） in his personal life. Coetzee is a vegetarian, a cyclist rather than a motorist and doesn't drink alcohol.

But what he has_______（64） to literature, culture and the people of South Africa is far greater than the things he has given up. "In looking at weakness and failure in life,"the Nobel prize judging panel said, "Coetzee's work_______（65） the divine （神圣的）spark in man."
