    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.

    I am a teacher in a middle school. I have a good friend called Mr White. He is the head of an office. He's often busy and has no time to do the housework. His wife knows him well and does all at home.

    Unluckily, their daughter Rose got hurt in a traffic accident two weeks ago, and had to be in hospital. Mrs White had to look after her there and she couldn't look after Mr White well. Mr White often ate in restaurants. As he never did any cleaning, the rooms were all in a mess(混乱) .

    Yesterday morning, before Mr White got up, the telephone rang. He sat up to answer it. His friend Tony told him to write down an important telephone number. But he could not find a pen or a piece of paper. He found there was much dust(灰尘) on the table and wrote the number on it with his finger. But soon he forgot about it and went to work.

    This morning, Mrs White and their daughter came back home.

    At noon, Mr White came in while Mrs White was cleaning the rooms. He sadly found the table was clean and the number was gone(不见了) .

    Most teens need more than 9 hours of sleep each night. But about 1 in 4 teens has trouble in sleeping. Lack of sleep can affect everything from our feelings to how well we focus on tasks like studying. It can also influence sports performance, increase our chances of getting sick, and may lead to weight gain in some people.

    How can we get the sleep we need? Here are some ideas:

    Be active during the day. Get at least 60 minutes of exercise a day. Physical activity can decrease stress and help people feel more relaxed. Just don't work too close to bedtime because exercise can wake you up before it slows you down.

    Say goodnight to electronics. Experts suggest using the bedroom for sleep only. At least shut everything down an hour or more before lights out.

    Keep a sleep routine. Going to bed at the same time every night helps the body expect sleep. Creating a bedtime routine can improve this relaxation effect. Reading, listening to music, spending time with a pet, writing a diary or doing anything else can relax you.

    Expect a good night's sleep. Instead of worrying that you won't sleep, remind yourself that you can. Say "Tonight, I will sleep well." several times during the day. It can also help to practise breathing exercises or gentle exercises before bed.

    Everyone has a sleepless night once in a while. But if you regularly have trouble in sleeping and you think it's affecting your mood or performance, talk to your doctor.
