Many years ago, most of our earth wascovered with blocks (块) of ice. These iceblocks were as tall as high buildings in modern cities. Most of the ice was inthe northern part of the world. Then the ice blocks started to move south. Coldand rain came with the ice. Animals had to move. At last, the ice began to melt(融化). After half a million years, most of it melted.More than half of the earth became covered with water. Theclimatebecame much warmer. Things began to grow. The earth began to look the way inwhich it looks today.

    When people think of tigers, words like" strong" and " dangerous" come into their mind. But now, the big animal is calling for our help. There were once eight kinds of tigers in the world, but three died out during last century. In the past 70 years, the number of Siberian tigers has gone from as many as 300 to somewhere between 18 and 22.

   World Wildlife Fund started a programme. It is about to put an end to tiger poaching(非法狩猎) and save wild tigers. China, together with 12 other countries, has joined in. The aim is to double the number of wild tigers in the next ten years.

According to the research by Chinese officers and WWF, the Siberian tiger is already one of the planet's most endangered animals. "If the government doesn't do anything, it's quite possible that there will be no more Siberian tigers in China in 10 to 20 years." said Zhu Chunquan, director at WWF Beijing office.

    Wild animals such as deer and wild bears are tigers' main food. The poaching of these animals is the greatest danger to tigers. Another one is the trap(陷阱). "Volunteers from WWF remove traps every year, but we cannot clear all the traps ourselves," Zhu said. The most important thing people can do is to save the animals tigers eat." To protect the tigers, we need to call on more people to stop hunting wild animals."

When we talk about music, we can think of different {#blank#}1{#/blank#} of music.

Some people like pop music very much, but it often comes and goes so {#blank#}2{#/blank#}. Pop music shows people's feelings of love, friendship, joy and worry in {#blank#}3{#/blank#}, so it's quite popular with young people.

Classical music isn't so popular with young people {#blank#}4{#/blank#} it's the symbol of high music level. We know that classical music sounds {#blank#}5{#/blank#}, and some people can't get its real meaning. That's {#blank#}6{#/blank#} it's not popular with young people.

Folk (民间的) music is different from other music. It is more {#blank#}7{#/blank#}. In American history, folk music began to show up when people needed it most. The {#blank#}8{#/blank#} folk songs are those like Down by the Riverside and We Shall Overcome. The songs are about hard life, {#blank#}9{#/blank#} they are also full of hope. In folk music, people can {#blank#}10{#/blank#} their wishes and dreams about the future. That is why almost everyone can understand it.

Spring is a season full of wonders, while rain has been a popular topic in poems all over the world. Let's see how poets Du Fu (712-770) from China and Sara Teasdale from the US wrote about spring rain.

 Oct 16 is World Food Day. So what can you do {#blank#}1{#/blank#} ( help) hungry people? Now you can play a game and make the world a {#blank#}2{#/blank#} ( good) place at the same time. It's called Freerice.

 My geography teacher in high school told us {#blank#}3{#/blank#} this game. It's an educational trivia game(益智问答游戏) and it's so special. If you answer a question {#blank#}4{#/blank#} ( correct), you will raise 10 grains(粒) of rice for the United Nations World Food Programme (WFP) to support its work saving and changing lives worldwide.

{#blank#}5{#/blank#} I first started playing, it only had English trivia questions. But now it can test you on arts and culture, math, science, languages, and more.

I now like to use it to practice my Chinese and also geography — two favorite subjects of {#blank#}6{#/blank#} (I). It's also good because it fits all ages and has different difficulty {#blank#}7{#/blank#} ( level). Besides, you can play by yourself or even make a group with your family, friends or classmates.

 According to the Freerice website, since 2010, Freerice has raised more than 214 billion grains of rice for people in need. That is about US $1.41 million. One top donator(捐赠者) is a {#blank#}8{#/blank#} ( use) named Handsome JFr. He has donated 63,925,020 grains of rice!
