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.

    Alice and John are in the music club at their school. Alice plays the violin and John plays the drums. There are two groups in the school music club: the training (训练) group and the concert(音乐会) group. Everyone starts in the training group!

     "When I first started to play the violin it sounded terrible!" Alice said. "My family asked me to practice outside."

    After a year's practice, Alice and John play much better now. They are both in the concert group and they are learning more difficult music. "We're learning the music from the film Pirates of the Caribbean. It sounds fantastic!" John said. "Playing in the club with other kids is a lot of fun."

    Playing an instrument (乐器) is not only fun. It also helps children learn to concentrate (集中注意力). "I have to concentrate when I'm practicing," Alice said. "And now it's easier for me to concentrate on my schoolwork."

    Playing an instrument can also help children become more confident (自信的). As John said, "I was scared when I played in front of a lot of people for the first time. But now I really enjoy it."

    When I was young, my family lived a hard life in the country. The roads in the country are not good. {#blank#}1{#/blank#} One evening we were visiting some relatives and the weather was very bad.{#blank#}2{#/blank#} Dad carried me on his back. Mum gave her coat to my brother. We walked together in the rain for more than one hour.

    I was fat at that time and Dad held me for a long time.{#blank#}3{#/blank#} He almost fell down many times. I tried to get down and walk myself, but I couldn't do anything because I was just a little kid.

    {#blank#}4{#/blank#} The rain had come through the leak(有裂缝的) roof and water was everywhere. Mum put bowls all around the house to try to catch the rain. {#blank#}5{#/blank#} She carefully placed us on the remaining dry place. I fell asleep soon. When I opened my eyes, I found Dad and Mum were sleeping in chairs, both having caught a bad cold.

A. As you can imagine they are difficult to walk on.

B. I thought he must be tired.

C  It began to rain on our way back home.

D. Then she put me and my elder brother to bed.

E. We didn't say any word on the way.

F. When we arrived home, the inside of our house was full of rain water.

    Can you imagine a sea of sand three times bigger than India? This is the Sahara Desert, the largest desert in the world. It covers 11 countries in North Africa and is over 9 million square kilometers.

    In the Sahara, temperatures are very different during the day and at night. It is much hotter during the day than at night. During the day, the hottest time is between 2 p. m. and 4 p. m.-when temperatures rise to 33℃. But it is very cold at night, the coldest time is at 4 am, when temperatures fall to -1℃.

    Because of the extreme temperatures in the desert, it is a very difficult place to survive (幸存). Marco Rivera, our survival expert, has some tips.

    Take warm clothes and a blanket. You will need a hat, long trousers and a thick sweater to keep you warm at night. During the day, cover your body, head and face. Clothes protect you from the sun and keep water in your body. You will also need a warm blanket at night. It can get cold rapidly. When the temperature drops, it can be a shock and make you feel even colder.

    Try to drink some water at least once every hour. You need your water to last as long as possible. Drink only what you need. If you eat, you will get thirsty and your water will run out soon. You can eat a little, but only to stop you from feeling very hungry. Eat a small amount of food slowly.

    It's important to stay out of the sun during the day. Make a hole under your car and lie there. This will keep you cool and help you sleep. Find a warm place to sleep at night. A small place near a tree or a rock will be the warmest. But be careful before you decide where to sleep. Dangerous animals like snakes also like to sleep in these places. Look carefully for animals before you lie down.

    The Silk Road is known all over the world.{#blank#}1{#/blank#}It went along the north of China, India, and Persia and ended up in Eastern Europe near today's Turkey and the Mediterranean Sea.

    It was called the Silk Road because one of the major products traded was silk cloth from China. Chinese silk was soft and of high quality. So people throughout Asia and Europe loved it very much.{#blank#}2{#/blank#}Even the Romans called China the "land of silk".

    Besides silk, the Chinese also sold tea, salt, sugar, porcelain(瓷器)and spices(香料). Most of the goods were expensive. This was because it was a long trip and trades didn't have a lot of room for goods. They bought goods like cotton, ivory, wool, gold and silver.

    Traders traveled in large caravans (商队). They would have many guards with them.{#blank#}3{#/blank#}Most of the road was through dry land, so camels were popular animals for transport.

    Although there was some trade between China and the rest of the world for some time, the silk trade developed quickly during the Han Dynasty which ruled from 206 B. C. to 220 A.D.{#blank#}4{#/blank#}During this time, Chinese traders traveled safely. Also, traders had a higher social position.

    {#blank#}5{#/blank#}It not only helped develop trade between different countries, but also helped make ideas, cultures and inventions spread across the world.
