    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 everyday attention.
    Pay more attention to your diet. First, eat food that is good for your eyes. They are fresh fruits and vegetables as 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 the eye muscles(肌肉)and gives them the rest required. Sleep not only helps the body to repair its tired tissues (组织). 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) yours eyes at regular periods, which makes the eyeballs watery, and gives them a good wash.
    We use our eyes in many unnoticeable and wrong ways. Fox example, if a small thing goes into our eye we start rubbing it, which is wrong. Rubbing can cause damage(伤害) to 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, writing, watching television 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.

    Happiness is important for everyone. Most people want to be happy but few know how to find happiness. Money and success don't bring lasting happiness. Happiness depends on ourselves. In other words, we make our own happiness.
    Some people believe that if they are wealthy, they will be able to do anything they want, which means happiness. On the other hand, some people believe that holding a high position in the government is happiness. In this way, you have not only money, but also many other things which can't be bought by money. However, other people believe that having lots of money is not happiness, nor is holding a high position in the government. These people value(重视) their beliefs, or their intelligence, or their health. They think these can make them happy.
    Here are a few ways to help you be happier.
    The first secret of happiness is to enjoy the simple things in life. Too often, we spend so much time thinking about the future, for example, getting into college or getting a good job, that we don't enjoy the present. You should enjoy life's simple pleasures, such as reading a good book, listening to your favorite music, or spending time with close friends. People who have close friends usually enjoy happier and healthier lives.
    The second secret of happiness is to be active. Many people go dancing or play sports. People can forget about their problems and only think about the activities.
    Finally, many people find happiness in helping others. According to studies, people feel good when they volunteer their time to do many meaningful things for other people. If you want to feel happier, do something nice for someone. You can help a friend with his or her studies, go shopping to get food for an old neighbor, or simply help around the house.
    Now maybe you know how to find happiness!

   The London Olympic Games are coming soon. This summer, Chinese sports fans will be able to watch the exciting games in 3-D on CCTV.
    When you watch 3-D movies or TV, you have to wear a special pair of glasses. The 3-D glasses make the people and the things on the screen look like they are in the room with you.
   3-D, means having three dimensions: width, height and depth. 3-D technology is based on the way the human brain and eye work. Because the pupils of a person's eyes are about 6.5 cm apart, when we look at something, each eye sees it from different angle. Our eyes send the two pictures to our brain, and the brain puts them together. The small difference between the picture from the right eye and the picture from the left eye make us see depth.
   While watching 2-D films, we don't have to wear the special glasses. We see the pictures in two dimensions, each eye get the same information. This is because there is only one way of watching it.
   So the aim of 3-D technology is to get a different picture into each eye of the person. It uses two film projectors. One projects a left eye picture and the other projects a right eye picture. When we are in the cinema, we can see different pictures in each eye at the same time with the help of the 3-D glasses.
   While watching 3-D films, we feel that we are actually in the same environment as the things we are watching. However, some people are against watching 3-D films. One of the reasons is the 3-D glasses makes the screen of the film or TV look darker. It is bad for eyes. What's more, people with eye problems may get headaches if they spend too much time watching 3-D movies, because their brains need to work harder to “read” the pictures.
