It's said that eyes are the windows of our soul. Beautiful and bright eyes not only show a good health but also make you look 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 well as fish, eggs and milk. Besides, a regular amount (数量) 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. 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 eyes.

    You must exercise your eyes every day. Blink (眨眼) your 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. For example, if a small thing goes into our eye, we start rubbing (揉) it, which is wrong. Rubbing can cause damage 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 TV or working on the computer can also cause eye tiredness.

    About the year 1900, Charlie Chaplin (卓别林) was often seen waiting outside the back entrances of London theaters. He looked neither tall nor short. He was hoping to get work in show business. Luckily, he soon got a chance to act and it was also his first performance on the stage.

    But twenty years later, this same Chaplin became the greatest, best-known comedian (喜剧演员) in the world. Any regular visitor to the cinema must have seen some of Charlie Chaplin's films. People everywhere have laughed at them until tears have run down their faces. Even people who don't understand English can enjoy Chaplin's films because they mostly have no sound. It isn't what he says that makes us laugh. It is based on little actions which mean the same thing to people all over the world.

    Chaplin lived most of his life in America and died in Switzerland on Christmas Day in 1977, at the age of eighty-eight. There was sadness all over the world at the news of his death.

    Great white sharks (鲨鱼) in the Pacific Ocean. Wildebeest (角马) in Africa. Arctic terns (北极燕鸥) in the Atlantic. At first, these animals seem quite different. One swims, one walks, and the other flies. But they all have one thing in common. They all migrate (迁徙).

    Some migrating animals move to a place with better temperatures. Some go to find food or water. The groups travel as one, but during the trip, they face many different challenges.

    One challenge is distance (距离). Some migrating animals take very long trips. For example, one great white shark swam from Australia to South Africa and back. In nine months, it swam about 20, 000 kilometers!

    Another challenge is finding enough food or water during the journey. For example, each Mali elephant needs over 200 liters (升) of water each day. To get this, they need to go from one waterhole to another.

    Besides, migrating animals have to keep away from other animals because they want to eat them. The zebra (斑马) has to avoid lions. Traveling as a group helps keep them safe. When one zebra is in trouble, the other members make a circle around it.

    By working as a group, migrating animals travel to live better lives.

    When I just moved to Los Angeles（洛杉矶）, I didn't have a car.{#blank#}1{#/blank#}, but I wanted to prove（证明）them wrong.

    I asked my neighbor, Mrs. White, to take me to the bus station in the center of the city, so I could try taking the bus home.{#blank#}2{#/blank#}. When I got there, I went inside and got a bus timetable（时刻表）. I looked at the map and worked out that I needed to take three buses to get home.

    I bought the tickets and went outside to wait at the bus stop for the Number 8 bus. {#blank#}3{#/blank#}. I gave my ticket to the bus driver and took a seat. At the right stop I got off. {#blank#}4{#/blank#}. I waited and waited. A man was also waiting for the same bus. He said that it wasn't unusual for the bus to be late. Half an hour later, it finally came. To make the matter worse, the third bus broke down halfway and the driver had to fix it. {#blank#}5{#/blank#}. So when I finally got home, I was very tired. Maybe getting a car in Los Angeles wasn't such a bad idea!
