参考答案：B, C, D
When my son, Mark, was in the third grade, he saved all his pocket money（零用钱） for over three months to buy holiday presents. The third Saturday in December Mark said he had made his list and had twenty dollars in his pocket.
I drove him to a nearby supermarket. Mark picked up a hand basket and went in while I waited and watched in the car. It took Mark over 45 minutes to choose his presents. Finally he came to the checkout counter (交款处) and reached into his pocket for his money. It was not there! There was a hole in his pocket, but no money. Mark stood there holding his basket, tears falling down his face.
Then a surprising thing happened. A woman came up to Mark and took him in her arms."You would help me a lot if you let me pay for you," said the woman."It would be the most wonderful gift you could give me. I only ask that one day you will pass it on. When you grow up, I would like you to find someone you can help. When you help others, I know you will feel as good about it as I do now." Mark took the money, dried his tears and ran back to the checkout counter as fast as he could. That year we all enjoyed our gifts almost as much as Mark enjoyed giving them to us. I would like to say "thank you" to that very kind woman, and tell her that four years later, Mark went house to housecollecting blankets (毯子) and clothes for the homeless people in the fire. And I want to promise （许诺）her that Mark will never forget to keep passing it on.

| 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 (狼图腾) 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 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! | ||||
