Tom has a strong and faithful(忠诚的) dog, Bruce. The dog likes playing with Tom. Sometimes he also follows Tom's father to work.

    One morning when Tom's father worked in the field, he took off his coat and put it on the ground under a big tree. He turned to the dog and said, "Watch my coat, Bruce!"

    Bruce sat down on the coat. Later Tom's father remembered he had to buy some food. So he hurried to the shop. After shopping, he went home directly and forgot all about his coat and the dog.

    Late in the evening Tom looked for his dog everywhere in the house, but he couldn't find him. At this time Tom's father suddenly remembered his coat and the dog. He went back to the tree at once. He found that Bruce was still sitting on the coat!

    Jackson was excited！He and his family were on their way to the White House, Jackson could not wait to see the President's official residence. He had been reading all about it so that he might recognize some things he saw. After standing in a long line, Jackson, his sister, and their parents were allowed to enter the 132-room, six-floor mansion. They entered through the East Wing. Jackson knew that he and his family were only four of the 6, 000 people who would visit this incredible house that day.

    The first room they were shown by the guide was the State Dining Room. Jackson learned that 140 dinner guests could cat there at one time. "What a great place for a huge birthday party！"Jackson thought.

    The Red Room was shown next. Red stain(绸缎)adorned its walls. The third room the visitors entered was the Blue Room. This room serves as the main reception room for the President's guests. Jackson wondered when the President would be out to greet him. After all, he was a guest, too.

    The Green Room was the fourth room on the tour. Jackson and his family were not surprised to find green silk covering the walls in this room.

    The last room was the biggest room in the White House. It is called the East Room. Here guests are entertained after formal dinners. Jackson wondered if they could vary the entertainment by rolling in huge movie screens so they could all watch the latest movies. He wondered if kids were invited sometimes; maybe they had huge, bouncy boxes you could jump in. Perhaps they even set up huge ramps(坡道)so all the kids could practice skateboarding and roller blading. How fun！

    Jackson loved his tour of the White House. He was just sorry that he did not get to see the living parts of the President's family. He wondered if the President had to make his bed every day！

    Mr. Jones and Mr. Brown work in the same office (办公室). One day Mr. Jones says to Mr. Brown, "I will have a small party at our house on Monday evening. Would you and your wife like to come?"

    Mr. Brown says, "Thank you very much. I'd love to, but let me ask my wife first." So Mr. Brown goes to the other room and telephones his wife. Then he comes back and looks very worried.

    "What's the matter?" asks Mr. Jones. "Is you wife there at home?"

    "No," answers Mr. Brown." She isn't there." My small son answers the telephone. I say to him, "Is your mother there, David?" and he answers "No, she isn't in the house." "Where is she?" I ask , "She is somewhere outside(在外面). ""What's she doing? ""She is looking for me."

    The Sixth Time I Went to the Principal's Office When I was in the seventh grade, I had problems behaving. My heart was in the right place, but I couldn't always follow the rules. I played many tricks on my schoolmates. Once, I even pulled a girl's hair on the school bus to get her attention. As a result, I was repeatedly sent to the office of the principal(校长).

    Although I hated going there, I did not hate the principal, Mr. Ratcliff. Mr. Ratcliff was a kind, elderly man. When he spanked(打屁股)me for putting some ants into a classmate's pencil box, it didn't hurt at all, but it did hurt my feelings. I thought so much of him and moments like that seemed to prove I was hopelessly bad.

    When I got called to Mr. Ratcliff's office for the sixth time, I had no idea what I had done. I felt disappointed as I walked down there. I went into his office, sat down, and looked at the floor. Then he said the last thing I expected to hear:"

    Kevin, I've heard you've been behaving really well lately. I want you to know how proud I am of you, and I just called you down to my office to give you a peppermint."

    "Really?" I was surprised.

    "Yes. Now you can take that peppermint and go back to class."

    I carried the peppermint with me as if it was a gold coin. When I got into my classroom, I bragged(吹嘘)to my classmates about my turnaround, excitedly. I wasn't so bad after all.

    Mr. Ratcliff was really kind. He made me realize that I was just a kid who had problems with behavior. He bought some peppermints and took the time to notice me when I got something-anything-right. Mr. Ratcliff gave me some hope by giving me some love. I will just remember him for the rest of my life.
