    Littering is a big problem in cities around the world. People know it does harm to the environment, but few do something for years to make a difference. However, "Butt Lady" sets an example to all.

    The true name of "Butt Lady" is Sally Dawly. She lives in Auburn, a city in California, US.{#blank#}1{#/blank#} because she had spent most of her free time picking up cigarette butts (香烟头) from the streets of her city. After picking up one million cigarette butts in three and a half years, she has set a new goal for herself-two million cigarette butts.

    Dawly got tired of going on her walks and seeing cigarette butts everywhere, so in 2014 she started to take action. Armed（装备）with a broom(扫帚), dustpan and a pair of tongs, the anti-littering activist walked down the streets in search of cigarette butts, picked them up and threw them in the trash can. To see how many butts she picks up, the Butt Lady has been using a counting device (装置).{#blank#}2{#/blank#} after picking up as many as 3,000 butts a day. She said she wanted to shout "Come on people. Don't throw your butts.{#blank#}3{#/blank#}."

    Dawly knows it's not easy to completely solve her city's cigarette butt littering problem in no time, but she hopes her efforts will help smokers think twice before throwing away butts on the street.{#blank#}4{#/blank#} as she has got more and more supporters in the city.

    Peter wanted to travel, especially to English-speaking countries such as America and Australia. But he knew that he had to improve his English, so he went to Green Language School to take English lessons. Peter worked very hard at his English. At last, he became ill. Every evening he went to bed, closed his eyes but he stayed awake(醒着的).

    Peter was worried so he went to see the doctor." I can't sleep at night. What should I do, Doctor?"

    "I have a piece of advice, "said the doctor. "Try to count(数)numbers. When you count up to 1,000, you'll be asleep."

    The next day Peter returned to the doctor's office." Did you try my advice？And are you better today?" asked the doctor.

    Peter wasn't happy. "Er, I tried counting from one, two...up to four hundred and twenty-one, and I felt sleepy. Then I got up and drank some coffee. Then I went on counting up to 1,000. But I still couldn't be asleep."

    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.
