People like to read stories about dog very much. They thought dogs were very clever.

    One of my good friend , Bob ,had a very big dog . Its name was Bill. Every Sunday afternoon, Bob and Bill had a walk in the park , Bill liked walking with Bob very much.

    I visited Bob last Sunday. I stayed in his house for a long time. Bob and I talked with each other happily. Soon it was time for them to go for a walk in the park . We forgot that. Bill began to worry about it. He walked around the room and sat down in front of me and looked at me. But I didn't know this. I went on talking with my friend. At last, Bill couldn't wait. He went out of the room and came back soon. He carried my hat in his mouth. Oh, I knew what Bill meant.

    Tim, Bob and Frank lost their schoolbags. They are in the Lost and Found case. The schoolbags are the same, but the things in them are different. Can you help them find the right schoolbag?

Tim: I have a math book and a pencil box in my schoolbag. There are three pencils, a pen and an eraser in the pencil case.

Bob: I have a Chinese dictionary, a math book and two notebooks in my schoolbag.

Frank: There are two CDs and three picture books in my schoolbag. My English books are also in it.

    It seems very natural that if you have two dollars and add two dollars to them, you have four dollars. But do you know it too men millions of years to be able to think so? In fact, one of the most difficult things to teach children is the idea of numbers.

    In ancient times, when a man wanted to tell how many animals he owned. he had no system(系统) of numbers to use. He put a stone into a bag for each animal. The more animals, the more stones he had. It may explain why the word "calculate" comes from the Latin word "calculus", "calculus" means "stone."

    Then, man used lines to count. People would just draw a line for each thing they wanted to count, but they had no word to tell the number.

    Later on, people used fingers. Again we have word that goes back to this. The word "digit" comes from the Latin word "digitus". It means "finger"! And the fact that we have 10 fingers led to the use of 10 in the system of numbers.

    The number system we use today was invented by the Hindus in India thousands of years ago and was brought to Europe during 8^th to 11^th by Arab traders(商人). In this system, people count things with ten numbers. 1. 2.3.4.5.6.7.8.9.and 0. It is decimal system(十进制), that is, it is built on the base of 10.

There are different opinions about who invented the umbrella. Some people say that the people of ancient Egypt invented it, some say the Romans invented it and some say Luban's wife invented it in ancient China. There's even an interesting story about its invention in China.

Luban was the most famous craftsman(工匠) in ancient China. One day, Luban and his wife were taking a walk and enjoying the beautiful view. Suddenly it began to rain. Both of them were wet when they went back home. Luban's wife said, "If there is something that can protect people from the rain when they are walking outdoors, it will be wonderful." Then Luban said,"That's easy. I will build many pavilions(亭子)." His wife replied, "That's a good idea, but it is not convenient.Is it possible to make a movable pavilion, which could always follow the people?"She thought about it all day and night.

One day, she saw some kids playing in the rain, and each kid held a big lotus leaf over the head to protect themselves from getting wet. That gave her great inspiration. Then, she made the first umbrella in ancient China.

Since the umbrella was invented, it has been part of people's lives in every corner of the world. Right now, there are many kinds of umbrellas, such as beach umbrellas, kid umbrellas and market umbrellas.

How many umbrellas are made every year in the world? Maybe millions or even more. One interesting thing is that most umbrellas in the world are made in China. Shangyu in ZhejiangProvince alone has more than 1,000 umbrella factories and it is called"China's Umbrella City".
