Deserts are found where there is little rainfall or where rain for a whole year falls in only a few weeks' time. Ten inches of rain may be enough for many plants to survive (存活) if the rain is spread throughout the year, If it falls within one or two months and the rest of the year is dry, those plants may die and a desert may form.

    Sand begins as tiny pieces of rock that get smaller and smaller as wind and weather wear them down. Sand dunes (沙丘) are formed as winds move the sand across the desert. Bit by bit, the dunes grow over the years, always moving with the winds and changing the shape. Most of them are only a few feet tall, but they can grow to be several hundred feet high.

    There is, however, much more to a desert than sand. In the deserts of the southwestern United States, cliffs (悬崖) and deep valleys were formed from thick mud that once lay beneath (在……之下) a sea more than millions of years ago. Over the centuries, the water dried up. Wind, sand, rain, heat and cold all wore away at the remaining rocks. The faces of the desert mountains are always changing--very, very slowly--as these forces of nature continue to work on the rock.

    Most deserts have a surprising variety of life. There are plants, animals and insects that have adapted (适应) to life in the desert. During the heat of the day a visitor may see very few signs of living things, but as the air begins to cool in the evening, the desert comes to life. As the sun begins to rise again in the sky, the desert once again becomes quiet and lonely.

Kunqu Opera (昆曲),also known as Kun Opera, is a kind of Chinese musical drama (戏剧).But it is more than just drama. It is actually a kind of art{#blank#}1{#/blank#}history, music, dancing and others.

It is {#blank#}2{#/blank#}believed that Kunqu Opera is the beginning of all the other forms of Chinese opera. With a long history of over 600 years, Kunqu Opera started in the city of Kunshan at the end of the Yuan Rynasty. It became quite {#blank#}3{#/blank#}in the Ming and Qing dynasties. In 2001,Kunqu Opera was {#blank#}4{#/blank#}as one of the Masterpieces of the Oral and Intangible Heritage of Humanity (人类口述和非物质遗产代表作).

    We are lucky to live in a rich country where we have many things. However, most of us usually {#blank#}1{#/blank#} (waste) some things.

    Electricity is one thing that we waste most. Lights, TVs, {#blank#}2{#/blank#} (radio) and other things are often kept on even when no one is using them. We should turn them off {#blank#}3{#/blank#} we do not need them. It takes  {#blank#}4{#/blank#} (little) than a second to do it. Anyhow, not wasting electricity saves money, because we do not have to pay for the electricity we do not use. The {#blank#}5{#/blank#} (two) thing that we often waste is water. Fresh water is precious, so it shouldn't be wasted. It is only a simple matter of turning {#blank#}6{#/blank#}a tap. I am sure everybody can do this {#blank#}7{#/blank#} (easy) if he wants to. Another big waste is food. My mother used to cook so much food that much of it was thrown away. I told her we had wasted so much {#blank#}8{#/blank#} (food). She thought I was right and now cooks mainly what we can eat.

    It is not right to be wasteful. I find there is a simple way of not wasting things. That is {#blank#}9{#/blank#} (use) only what we need. Do not touch what we do not need. {#blank#}10{#/blank#}this way, we can stop being wasteful.

The Art of Paper

    Chen Zijiang is a paper cutting expert whom I interviewed for my article on Chinese Art. Paper-cutting is something that he learned to do from an early age.

    "It is a Chinese folk art with a long history," Mr. Chen told me, "Paper cuts of animals have been found in tombs. {#blank#}1{#/blank#}" He added that by the Southern Song Dynasty, paper-cutting had become an important part of everyday life.

    {#blank#}2{#/blank#}They are paper cuts for decoration, for religious purposes (宗教目的) and for design patterns.

    Paper cuts for decoration are often seen, on windows and gates. {#blank#}3{#/blank#}They are also used on presents. A present for parents whose child has recently been born might show a paper cut of children, for example. Paper cuts which show the Chinese character for double happiness are often used to celebrate weddings.

    Paper cuts for religious purposes are often found in temples{#blank#}4{#/blank#}

    The third kind of paper cuts are these used to make patterns on clothing. They are also sometimes used to decorate jewelry (珠宝) boxes. {#blank#}5{#/blank#}.

    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 like not enough food, genes (基因) and aging (老化). 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, the best way is to clean your eyes by using 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 serve as a great way to protect your eyesight from ultraviolet rays.

    Eating healthy foods will do good to your eyesight. Remember that vitamins A, C and E are good for eyes. Try to eat food groups that have these vitamins. And you should do eye exercises because exercises protect your eyesight too. If a person exercises regularly (定期地) 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. Being happy all the time can be helpful to a person's eyesight too. In a word, eye care is very important, no matter how old a person is.
