    Ronny looked like every other kid in the classroom where I volunteered as the Reading Mom. However, he had a speech problem so he couldn't 1 like other kids in his grade.

     I worked with all the students in Ronny's class one by one to improve their reading skills. On the days when it was Ronny's 2, I'd give him a silent smile, that's why he sat very close to me and opened the book as if he was opening a treasure that 3 had ever seen.

    I watched his fingers move 4 under each letter as he struggled* to read out. Every time he 5 to read a word with a strange pronunciation, the biggest smile would spread across his face and his 6 would shine with pride, which broke my heart each and every time.

    A few weeks 7 the school year ended, I held an awards ceremony*. I presented Ronny with a book written by 8. A few days later, I returned to the school to visit. I 9 Ronny on a chair near the playground, the book open in his lap. His head teacher said, “ He hasn't 10 that book since you gave it to him. Do you know that's his first book he's ever actually owned?”

    Deeply moved, I walked 11 Ronny, placed my hand on his shoulder and asked, “Will you read me your book, Ronny?” For the next few minutes, he read to me more 12 than I'd ever thought possible from him. The pages were already dog-eared, like the book had been read 13 times already. When he finished reading, Ronny closed his book and said with great satisfaction, “ 14 good book!"

    At that moment,as a writer, I knew I would get 15 about my own writing and do what that writer had done, and probably still does — care enough to write a story that changes a child's life, care enough to make a difference.

    Miss Mitra didn't want to be a Sunday school teacher any longer. The students there were all rude and never listened to her. "I give up." She shouted at the students. "Cool." Rick said. He was the most impolite kid in this school. Two months later, Miss Betty Ray came to the school. She looked young. The students thought that she wouldn't stay very long.

    "Have any of you ever been out of state?" She asked in a friendly tone. A few hands went up.

    "Anyone has traveled to California?" One hand went up as the disrespectful(无礼的) laugh reduced.

    "Anyone visited outside the country?" No hands went up now. The silent kids were puzzled.

    Betty took a map of the world from her bag.

    "What else do you have there? Lunch?" Someone cracked.

    Betty smiled lightly and answered, "Cookies for later." "Cool," Rick quipped(困惑的).

    Then she pointed at a place on the map, "I was born here, and I lived here until I was about your age."

    "Is that Texas?" Someone asked.

    "No. Quite a long way from here. It is Mumbai in India."

    Betty fumbled again in her bag, this time pulling out some old wrinkled pictures along with a box of chocolate chip cookies. They passed the pictures around, viewing each with great interest.

    The kids studied them as they bit into the sweets.

    The hour quickly slid by as she told them her stories about faraway places and what the people were like there and how they lived.

    "Wow, this is as exciting as TV!" One young girl told her.

    Sunday after Sunday, Betty came to class, tying her lessons to their everyday lives. She told the kids how they could make a difference right now. The students grew to love her.

    Betty taught that Sunday school class for thirty years. At last, her hair grew into a natural gray.

    Every now and then, she received a letter from a former student. There was a doctor, a research scientist, a homemaker, a businessman, and many teachers among them. One day she pulled out a blue envelope from her mailbox. And there was a photo in it. Squinting her eyes, she smiled at the man in the photo, still seeing the boy in him. Standing in the rubble(瓦砾), in the city of Delhi, India, he came to help the homeless people in the earthquake. Some words were written in the upper part of the photo, "Because of you, I am here now."

    My friend John has got a restaurant in a big city. It is near a supermarket. He gets ten robots for the restaurant. Each robot costs (价钱为) 20, 000 yuan. The restaurant is not big, but very popular. Now more and more people come here for dinner.

    The robots have different jobs in the restaurant. Two robots cook different kinds of food; one washes the dishes; one cleans the floor and the others give food to the guests (客人).

    Although robots do most of the jobs in the restaurant, John is still very busy. He must do many things to keep the robots working well. Luckily, John is good at studying robots and he knows robots very well. I think in the future, there will be a lot of robot­themed restaurants (机器人主题餐厅) around the world.

    Many years ago, there lived an old man with his three sons, Dharma, Harrison and Keith, in a village. The man worked hard when he was young, so he had the largest farmyard and the most beautiful house in the village. However, his sons were all born to be lazy, which made him disappointed. He was worried that his sons would use up his money and starve to death.

    One day, the old man came up with a plan. He called his sons and said to them, "Look, my dear sons. There is lots of hidden gold in the land at the farmyard. If you work together, you may find it."

    In a wish to find out the gold, his sons worked hard from the morning to the evening digging and digging all through the land. Three days had passed, but they didn't find what they were looking for. They got frustrated and angry. They decided to give up and returned to ask their father.

    "There is no gold in the land. We are cheated."

    "Since the land has been dug soft, why don't you plant some crops there?" was the reply of the father to the sons.

    Off went the sons. Soon the whole once useless land was rich crops.

    "This is the real gold, my sons," said the proud father.

    But there is one thing that Toby doesn't 2about skiing. There are so many things to 3. The most important things are the skis and ski boots (滑雪板和滑雪靴), of course. He also has to wear big socks to keep his feet 4and long underwear (内衣) for his legs. And he can't 5his hat and mittens (连指手套).

    However, this year Toby was glad to have the8. One time Toby's hat flew off while he was going down the mountain. One of the teachers went and got it9him. The teachers also showed him10to stop faster and turn better. Lessons were not so bad after all!
