Can you imagine a world without a writing system for your language? It may be hard to picture it now, but a man named Sequoyah lived in such a world. Sequoyah was a member of a native American tribe(部落), the Cherokee. Cherokee people speak their own language, but for hundreds of years they did not have a system of writing. Without a writing system, the Cherokee had no newspapers or books before 1809.

    Sequoyah was probably born around the year 1770 and lived with his mother in a small village in the mountains of Tennessee. When he grew up, he became a blacksmith(铁匠). When he was doing business with those “English-speaking people”, he noticed that they used paper with marks to record their thoughts and ideas. Sequoyah called these pieces of paper with marks “talking leaves”. He began to wonder why people who spoke Cherokee did not have a way to write down their words.

    In 1809, Sequoyah decided to give the Cherokee their own “talking leaves”. At first he tried to make a different symbol for every word in the Cherokee language. But in that case, there would be so many symbols and too hard for people to remember, so he decided to make a picture for each syllable (音节). After much hard work, Sequoyah invented 85 symbols. In order to see whether it would work, he helped his six-year-old daughter Ayoka learn each symbol and found she could learn to read and write very quickly. Sequoyah's invention was a success!

    Before long, Sequoyah's writing system had spread far and wide. Cherokee people living in all different parts of the country learned to read and write. In 1825, Sequoyah's system was made the official written language for Cherokee people. To this day, Cherokee speakers still use Sequoyah's writing system. In some parts of the United States, you can see street signs and billboards written in both English and Cherokee. Sequoyah will always be remembered for his important contribution（贡献）to Cherokee people.

    It is said that the eyes are "the windows of our soul". Beautiful and bright eyes not only show a good health but also make you look very attractive. However, to have healthy eyes, you have to look after them properly. Your eyes need taking good care of.

    Be careful with your diet. First, eat food that is good for your eyes. They are fresh fruits, vegetables, fish, eggs, and milk. Besides, a regular amount of vitamins A and B2 should also be taken.

    A regular and sound sleep is a must. It relaxes your eyes and gives them enough rest. Sleep not only helps repair the tired body. Usually, you must sleep for at least seven to eight hours every day. Loss of sleep can give you dark circles under the eye.

    You must exercise your eyes every day. Blink(眨眼) your eyes at regular periods, which makes the eyeballs full of water and gives them a good wash.

    We use our eyes in many wrong ways. Fox example, if a small thing goes into our eye we start rubbing it, which is wrong. Rubbing can hurt your eyes. Don't read or write in poor or bright sunlight. Always use sunglasses as sunlight can cause eye tiredness. Light should not shine directly in your eyes.

    Too much reading, watching TV or working on the computer can also cause eye tiredness.

    Remember to always take care of God's most beautiful gift to you. Your life will be very colorless without your eyes.
