Rose was born on February 29th, 2004. By 2010, her parents had 6 birthday parties for her. But most(大多数) of them were on February 28th. One day, she knew that only February 29th was her real (真实的) birthday. It comes every four years, so she didn;t want to have birthday parties on February 28th any more. After that, she had only one party. That was in the year 2012. On that day her grandparents, all her uncles, aunts and cousins came to her home to celebrate her birthday. She got so many presents. She thinks it's much more interesting to have a birthday party every four years.

    Do you know oil platforms (石油钻井平台)? They pump out (大量生产) oil from under the ocean (海洋). There can be over 100 people living and working on an oil platform. {#blank#}1{#/blank#}

    The people on oil platforms do a number of different jobs. There are engineers, cooks, doctors, cleaners, etc. But the roughnecks (石油钻井工人) have the hardest job. {#blank#}2{#/blank#}It's hard, dangerous work.

    There are no weekends on oil platforms. Usually, people work every day for two weeks. Then they go back to land to have two or three weeks off from work.

    The people on oil platforms can play games and watch TV when they don't work or sleep. {#blank#}3{#/blank#}There's not much space, and you can't just go for a walk.

    Oil platforms are dangerous places. Everyone needs to work carefully.{#blank#}4{#/blank#}An accident (事故)on the platform Deepwater Horizon in 2010 killed eleven people and a lot of oil went into the ocean.

    After that accident, some people said that oil platforms were just too dangerous.{#blank#}5{#/blank#}So we still need people to work in these difficult, dangerous places.

    People burn coal, gas and oil to get energy But there are problems with these fuels (燃料). (A)________, these fuels cause pollution. Pollution makes the air and water unsafe for humans. Secondly, these fuels will not last forever. One day, we will run out of these fuels.

    Scientists are looking for new kinds of energy. One is heat from the Earth. We know that (B)地球中央非常热. We cannot reach the center of the Earth, but in some places the heat from the Earth's center comes to the surface of the Earth. Perhaps you know about some of these places One place is volcanoes (火山). It is very dangerous to go near an active volcano, (C) _______ we cannot use the energy from this.

    Another kind of heat from the Earth is hot springs (温泉). In these places, hot water comes to the surface of the Earth. If this water is near a town, the hot water can be sent in pipes (管道) directly to people's houses to heat them .In Iceland, this is a common way to heat houses.

    (D)In Australia, scientists are looking for ways to make energy using hot rocks under the surface of the Earth. They want to pump (抽水)water onto the hot rocks .When the water hits the rocks, it makes stream(蒸汽). The steam is piped to power stations where (E) it is used to make electricity. The electricity can then be sent all over the country.

    Two Chinese farmers sang "in the spring" in their small room after drinking in a late August evening in Beijing. A friend put their song on the Internet. And soon they became stars around China.

    Wang Xu, 44, is from Henan, and Liu Gang, 29, is from Heilongjiang. They are among the millions of farmers who have gone to the cities to work.

    "Although nobody pays attention to the music, I am singing happily, on streets, under bridges or in wild country, with no credit card, no girlfriend or a home with hot water, but only a guitar." They sing, "It is just like the life we live now." Wang said, "We are poor farmers, and you know people won't care about us."

    Their song is loved by millions of Chinese, including the people who are also from the countryside. Many people said they cried after listening to the song.

    Wang came to Beijing in 2000 and has tried many jobs. Each month after he paid 600 yuan for the house and bought food, there was little money left." I love music, and also want to make more money." Wang said." I never dreamed of standing on such a big stage."

    Liu came to Beijing in 2002. "I wanted to try my luck in the big city." He said. And now their dreams of music have come true. They are really the luckiest of all the farmers in China.

    One would think that campers would know not to break the branches off trees for firewood, drive fast around the campground, litter, or leave a fire not looked after, but I've seen people do all of these things. No matter where you put up your tent, here are five things not to do at a campground.

{#blank#}1{#/blank#}

    What's it like to be near someone who decides to arrive late at night? Last summer, on a rainy night at a state park in Vermont, we heard noises from excited kids and barking dogs very close to our tent after midnight. There is no beautiful way to set up camp in the middle of the night, so please, just don't do it.

{#blank#}2{#/blank#}

    No one thinks that his dog is annoying, but we all know that some pets are better off left home. The only thing worse than a camper who stands by lazily as his dog barks at passers-by for no reason at all, is that he leaves his dog at his campsite while he goes off for the night.

{#blank#}3{#/blank#}

    This is the most important and often unnoticed camping manner in the book. Nearly every campground has rules that do not allow noise late at night and early in the morning, but most places also don't have the staff to carry them out.

    You might accept leaving your bar of soap thinking that someone might have forgotten to bring theirs, but I can assure you that non one wants to use your leftover soap especially if it's hairy, so please take it with you.

    No matter how good your taste in music is, I'd say most people prefer quiet hours with the nature. The truth is that no one want to hear your music except for yourself. Headphones are a great invention, but since too many campers fail to pack them, don't forget your earlugs.
