Mr. and Mrs. Su don't often go out in the evening, but today they go out for a walk after supper. They go to the park and have a good time there. On their way home, Mr. Su says to Mr. Su, "Look! A woman is running in the street and a man is running after her." Mr. Su says, "What's the matter? Let's go and help her."

    Now the woman gets near them. Mr. Su asks, "Shall we help you?" "No, thank you," the woman says, "My husband（丈夫） and I are running home, and the slower (较慢的) one does the housework."

    One day when Jack was walking in the park, he saw a woman, who lived a few miles away, sitting on a bench(长凳) with a dog beside her. The dog was looking up at the woman.

    Jack walked up to the woman and said, "Hello, Sue, how are you? May I sit and talk with you for a while?" "Of course, please sit down," Sue said. Jack sat down next to Sue on the bench, and they talked quietly together. The dog continued to look up at Sue, as if waiting to be fed.

    "That's a nice dog, isn't he?" Jack said, pointing(指着) at the animal.

    "Yes, he is. He's handsome. He's a bit of a mixture(杂交品种), but that's not a bad thing. He's strong and healthy."

    "And hungry," Jack said. "He hasn't taken his eyes off you. He thinks you've got some food for him."

    "That's true," Sue said. "But I haven't."

    They both laughed and then Jack said, "Does your dog bite?"

    "No," Sue said, "He's never bitten anyone. He's always gentle and friendly."

    Hearing this, Jack decided to hold out his hand and touched the animal's head. Suddenly it jumped up and bit him.

    "Hey!" Jack shouted. "You said your dog didn't bite."

    Sue answered in surprise, "Yeah, I did. But this is not my dog. Mine's at home."

    One day, Mr. Smith is going to take a train to his hometown. When the train starts, one of his shoes falls to the ground. The train is running faster and faster and he can't pick it up. Then he quickly takes off(脱下) the other one and throws it on the ground near the fallen shoe. A little boy on the train asks him, "Why do you do that?" "I've already lost one shoe." Mr. Smith answers. "If a man picks them up, he may get a pair of shoes."

    I'm Lin Min. My sister Lin Li is a teacher, but she isn't in Beijing with us. She works in a small school in Yushu in Qinghai. She works very hard. Every morning after breakfast, she goes to four of her students' homes and brings them to school. At eight o'clock, the students have the first morning class. After four classes, they have lunch at school. During the lunch time, Lin Li tells some stories to them. The students like listening to her stories. The afternoon classes start at 13: 00 and finish at 16: 00. After school, Lin Li sends the four students back to their homes and gets home at 17: 00. In the evening, she doesn't watch TV or play computer games. She usually checks her students' homework. Then she goes to bed at 22:00

    Lin Li wants to do more things for her students. She is a great teacher, isn't she?

    Alan Smith is blind. He teaches blind children in his country. To show the world that the blind can also do something amazing, he walked across the world's largest salt desert, Salar de Uyuni, only with the help of a GPS.

    Walking across the desert is not easy for an able-bodied person, let alone(更不用说) a blind man. Before setting off, Alan spent three years training for the journey. He studied everything he could find about the place and asked for advice from other travelers. During his journey, he only took water, food and sleeping bags. He walked about 20 kilometers a day. He showed great perseverance(毅力)and finished the 140-kilometer journey in just seven days.

    The brave teacher thought his week-long journey was wonderful. He said, "The journey was quite good. There were snow storms and winds, but luckily I made it."
