    Many of us don't pay much attention to the importance of eye care. It is said that if you take care of your body, then you can surely be healthy. That is why our eyes should be given a lot of care. Natural eye care should be put in a number one place.

    There are several causes leading to poor eyesight(视力)like not enough food, genes(基因)and aging(变老).Televisions, computers and reading are also the causes of having poor eyesight. If you work in front of the computer, it is best to take a break every once in a while. Something dirty can cause redness and they will make you feel uncomfortable. It is bad for your eyes, too. If this happens, you'd better clean your eyes with cold water. You must also try your best to protect your eyes from harmful things. For example, sunglasses are not just for fashion but they can also be used as a great way to protect your eyesight from UV rays(射线).

    Eating healthy foods will do good to your eyesight. Remember that vitamins(维生素)A, C and E are good for eyes. Try to eat food groups that have these vitamins. And you should do eye exercises because exercise protects your eyesight, too. If a person often exercises and eats the right kind of food, his eyes will stay in good condition for a long time.

    All above are natural ways of eye care that help us keep healthy eyes. In a word, eye care is very important, no matter how old a person is.

    ①More and more people like bicycling and it is no surprise. It is fun, healthy and good for the environment. Maybe that's why there are 1.4 billion bicycles and only 400 million cars on roads worldwide today. Bikes can take you almost anywhere, and there is no oil cost!

    Get on a bicycle and ride around your neighbourhood. You may discover something new all around you. Stopping and getting off a bike is easier than stopping and getting out of your car. You can bike to work and benefit(受益) from the enjoyable exercise without polluting the environment. You don't even have to ride all the way.

    ②Folding(折叠) bikes work well for people when they ride the train. Just fold the bike and take it with you. You can do the same on an airplane. A folding bike can be packed in a suitcase. You can also take a common bike with you when you fly. But be sure to look for information by getting on airline websites. ③Not all airlines（航空公司） are bicycle-friendly to travelers.

    Health benefits of bicycling:

    It helps to prevent heart disease.

    We often see top students around us and everyone knows about them. Let us take Jenny as an example. She is the monitor of our class. She spends a lot of time working for our class. But she always gets good grades in all subjects. How do students like Jenny do that? When I asked her, she said, "Hard work is not the whole story. It's not how long you sit at the desk with your books open. It's what you do as you are sitting." In fact, we can see many top students spend fewer hours on their studies than their classmates. Jenny gave me some valuable suggestions.

    If your math teacher gives you five problems, you should do six. If your Chinese teacher gives eight pages of reading, you should read nine. The more you practice, the more you learn.

    Studying is a matter of your personal interest, so choose the way you are most comfortable with. Some people like working at night when the house is quiet, while others like doing their work early in the morning. However, others like studying as soon asthey arrive home from school while the work is fresh in their minds. No matter which way suits you, try to do your best.

    Studying is your business and the business comes before entertainment(娱乐). When you are studying, phone calls should go unanswered, TV shows unwatched, snacks given up. Studying is the only thing in your mind. Nothing can pull your attention away from what you are studying.

    Studying is like eating. You should eat a little at a time. You can plan what to do today, but don't do too much. When you can't finish the work you planned to do, you will feel stressed and may lose confidence. On the other hand, you will not study well without a good plan. It all de pends on how you manage your time.

    The students who hand in a clearly written paper are already half way to get an A.. Tidy papers are likely to get higher marks than messy ones. When you write clearly and do your work carefully, the thoughts in your mind are clear. You can avoid making more mistakes.

    Confidence(自信)is very important in daily life. It can help you to develop a healthy attitude(态度). A study shows that the people who are more confident are much happier. They can have more chances to make themselves successful. But how to be more confident? Here are some suggestions:

●Speak loud

    When you are not confident，you can't do well what you want to do. You speak in a voice so low that other people can hardly hear you. Try to speak loudly enough so that people can hear you clearly. The. high voice can help you become more confident.

●Play sports

    Physical exercise makes you tired but completely relaxed. A strong body helps you be full of confidence.

●Encourage yourself

    Write down a list of things you did during the day to see how many things you have done well. Did you finish your homework? Did you tell a joke that made everybody laugh? Give yourself praise for the good things you've done.

●Get rid of(消除)fear

    Fear comes along with failure(失败). But it's easy to overcome(克服)if you know that failure is part of your life. Don't hide your head just because you said something stupid last time. Try to start again and believe you can do better.

●Pick up a hobby

    If you like singing, sing as much as you can. In some ways, a hobby can make you outstanding. And it will make you happy and confident.

    When I was a little child, I dreamed to be a rich man who could fly around the world and take the first class (头等舱) on the plane. After I grew up, when I first took the first class, I felt like part of the rich group. I was filled with a sense of pride when sitting with those important people.

    Once I was on the plane, I noticed that the stewardess (空姐) was working all the time to make sure that first class passengers felt comfortable. I thought she must love her job very much, because she gave everyone a big smile. When the stewardess walked past my seat, I looked up at her and said, "Thank you and I hope you have a great night." She stopped with a look of surprise on her face, and said, "Excuse me?" I said my words again. It seemed that I asked a question that she did not know how to answer.

    A little later, when I was getting off the plane, the stewardess said to me, "Thank you very much, sir." Then she said, "You are the only passenger who has thanked me or said anything nice to me all night." The pride of being part of rich group disappeared as soon as I heard these words. Then I came to understand that taking the first class didn't mean you were a real "first class" person.
