    Elena jogged with her dad in some empty lots(空地)at the edge of town. These out-of-the-way lots were good places to jog. But the lots were full of rocks and rubbish.

    One day, Elena saw a sign on the lots. It said, "New City Park. " Elena was excited.

Maybe the park would have a jogging trail(小路)！Elena told her parents about the sign.

    "I read about the park in the newspaper, "said Elena's father. " The city wants volunteers to help clean the area. Then the city will build a soccer field and a playground. "

    "Will they build a jogging trail? "Elena asked.

    " No, the paper didn't mention a jogging trail. "

    "Well, perhaps if I help clean up the lots, they'll put in a jogging trail, "said Elena.

    On Saturday Elena went to the lots. Many adults were working there. Some were picking rubbish. Some were moving rocks. "I want to volunteer, "Elena told a man, "What can I do? "

    "This is not a job for children, "said the man. " You'd better go home. "

    Elena looked around. She could carry rubbish. She could move rocks. A lady was pulling a bag of rubbish. Elena saw a box of rubbish bags. She took an empty bag. " I'll take this bag to the Dumpster, "said Elena, "Here's a new bag. "

    "Thanks, "said the lady. " Keep those new bags coming. "

    Elena dragged rubbish bags. She told everyone she was glad to help build the park. She explained that she hoped the park would have a jogging trail.

    Elena went to the area every week. Soon everyone knew her and she told everyone how wonderful a jogging trail would be.

    Soon the volunteers cleared the lots. The city could start building. The mayor gave a speech. He showed a drawing of the new park. He told them about the soccer field and the baseball diamond. There would be picnic tables. There would be a playground. The park would even have basketball courts. There was no sign of a jogging trail.

    The mayor thanked the volunteers. Then he asked if they had any suggestions. The volunteers said they wanted to build a jogging trail around the park. They told the mayor how helpful Elena had been and how she wanted a jogging trail. The mayor said, "A jogging trail won't be hard to build. Let's do it！"Everyone clapped and cheered. Elena cheered loudest of all.

    This is Monica's day. And she thinks it is interesting and helpful. Let's read it together.

      Bob was only seven years old. One night Bob was at home {#blank#}1{#/blank#} while his parents were out for a party. He had often stayed alone before, so he wasn't afraid. As he waited for his parents to {#blank#}2{#/blank#} home, he watched a film on TV. His eyes became heavier and heavier as time {#blank#}3{#/blank#} by.

      Suddenly Bob's eyes opened wide-what was the {#blank#}4{#/blank#} in the next room? Bob heard the window being opened slowly. For a minute, Bob was so {#blank#}5{#/blank#} that he could not move, and his body felt like ice. He knew that he couldn't lose his head (惊慌失措) and began to think of the things he could do. Again he heard the sound of someone trying to climb into his home {#blank#}6{#/blank#} the window.

      Bob's drums were standing in the corner near the TV. "Wait, {#blank#}7{#/blank#} there is something I can do," thought Bob. He {#blank#}8{#/blank#} on his drums as hard as he could. The sound was so terrible that Bob {#blank#}9{#/blank#} even himself. He also surprised the man in the window, who {#blank#}10{#/blank#} away as fast as possible. How clever he was!

    In the time it takes you to read this sentence, the population of the Earth will have grown by 10 people. That may not sound much, but it is about 14,000 people an hour. That is the same as adding most of the population of Germany to the world every year!

    Most of these new people are born in developing countries. These countries are found in much of Africa, South America, and parts of Asia. In the developed countries of Europe and North America, the population is growing very slowly. This is because women in these countries have, on average, only one or two children. In the developing countries, many women have five or more children. In 1950, around one quarter of the world's population lived in the developed countries. By 2050, these countries will be the home to only around one tenth of the world's people.

    In the developing countries, more than one billion people already live below the poverty line (贫困线).These people don't have enough food to eat and they live in poor housing; children get little or no time at school and suffer from many kinds of diseases.

    The United Nations (UN) tries to guess population growth. At the beginning of the 21st century, the world's population was around six billion people. The UN has said that the world's population will level off at 12. 5 billion people by the year 2100. Other people think the world's population will continue to grow, reaching 14 billion people before it becomes stable or even falls.
