    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.

    There is a big supermarket near Mrs. Green's home. She usually goes there to buy food. The shop assistants are polite and helpful. The things are cheap, too. One day, Mrs. Green goes to the supermarket. She buys some noodles.

    Biscuits are also their children's favorite food. And she buys some milk.

    Her children always have milk for breakfast. Mimi likes fish and Tim likes hot dogs. She buys some fish and sausages(香肠)for them, too. Mrs. Green doesn't have any rice at home. So she buys a bag of rice, but she can't take it. It is very heavy. Her husband, Mr. Green is coming to the supermarket and carry (搬运)the rice.

    It is very cold outside. There comes a black car and it stops in front of a supermarket. A young woman is in the car. She is very hungry and wants to buy a hamburger to eat, but she doesn't want to go out on a so cold morning. At that time she finds a little boy playing in the street

    "Come on, boy!" she says to the boy. "Do you know how much a hamburger is in the supermarket?"

    "Two dollars each," the boy answers.

    She gives the boy four dollars and asks him to buy two hamburgers. "One is for you and the other is for me," she says.

    Some minutes later, the boy comes back. He is eating a hamburger. He gives the young woman two dollars and says, "Sorry, there is only one hamburger left."

    Most people always like to collect things. For example, they like collecting stamps, books, pictures.… But my friend Mr King likes collecting clocks. He has five hundred clocks now.

    There are clocks everywhere in his house. You can see shelves standing in every room. All the shelves are full of clocks. Though Mr King is glad to do this, his wife doesn't enjoy it at all. She has a lot of work to do every day. It's not easy for her to clean hundreds of clocks. She is also angry at the noise. Each clock keeps its own time, so she can hear clock strike(敲) almost any time during the day and the night. "There is something even worse. I am never able to know what time it is with so many clocks around."
