    I have a little dog. Her name is Lady. Sometimes she is g, but sometimes she is naughty. She spends most of her times s . Lady sleeps ten hours a day in a basket. It is her h . Lady plays with a ball for four hours after she w up. She eats three times a day for ten minutes each time. Her favourite food is bones and meat balls. She even chews(啃) on a chair leg for half an hour if nobody s her.

    Lady is a good watchdog. Lady uses fifteen minutes a day to bark at the peo-ple who want to come up to our garden and another fifteen minutes to bark at the neighbour's cat. The rest of the time Lady sits and w things around her.

    Little Gauss(高斯) was very good at Maths.

    One day his teacher told the class to add all the numbers from one to one hundred together. All the boys began to write the numbers down, but little Gauss didn't. He tried to find the answer quickly. He thought to himself, "If I add 100 to 1, I get 101. 99 and 2 is 101, and 98 and 3 is 101, too. When I reach 51 and 50, I have 101 fifty times. That is 5,050. "

    Little Gauss wrote the number in his exercise book and gave it to his teacher. The answer was right. The teacher and the other boys were all surprised.
