There is nothing more i{#blank#}1{#/blank#} to life than the sun. W{#blank#}2{#/blank#} the sun, all living things on the earth would die. The sun is a star. In the sky there are t{#blank#}3{#/blank#} of stars like the sun. They are as large as the sun and as hot as the sun. At night you can see many stars, but in the day you can o{#blank#}4{#/blank#} see one star-- the sun.

      The sun is much n{#blank#}5{#/blank#} to us than any other star. That is w{#blank#}6{#/blank#} it looks the biggest and brightest of all the stars. The distance (距离) of the sun from the earth is as m{#blank#}7{#/blank#} as 150,000,000 kilometers. Most stars are thousands of light-years a{#blank#}8{#/blank#}from the earth.

      Do you know what a light-year is? N{#blank#}9{#/blank#} in the world travels faster than light. It travels 300,000 kilometers per second. And one light-year is the distance that light can travel in one y{#blank#}10{#/blank#}.

The Dragon Boat Festival is a traditional Chinese festival. we Chinese have {#blank#}1{#/blank#} for over 2,000 years. It's {#blank#}2{#/blank#} of the three most important lunar festivals in China. The Dragon Boat Festival takes {#blank#}3{#/blank#} on the 22^th of June this year.

Throughout the years, many stories have been told about the {#blank#}4{#/blank#} of this festival. Among them, the most famous one is about Qu Yuan, a well- known scholar in ancient China. He not only wrote good {#blank#}5{#/blank#} but also gave suggestions to the king. {#blank#}6{#/blank#} he devoted(贡献) himself to his {#blank#}7{#/blank#} , the king didn't like him. This great person drowned(溺水) himself in the Miluo River on the 5th day of the 5th Chinese lunar month because his Chu State fell to Qin State. Local people tried to save him or find {#blank#}8{#/blank#} body, but they didn't succeed. Qu Yuan was later considered as a {#blank#}9{#/blank#} hero. To remember him, every fifth day of the fifth lunar month, people beat drums and go boat racing on the river as they once did to keep fish away from his body.

Dragon boat racing is one of the most important customs Chinese people practice to celebrate the Dragon Boat Festival. This activity is held {#blank#}10{#/blank#} in China's southern and southeastern areas where there are lots of rivers and lakes.
