Electricity is a type of energy that was discovered over 100 years ago. One of the most common w{#blank#}1{#/blank#}  to make electricity is by changing other energy sources (来源), such as coal, and oil or solar, wind and falling water. You may not even realize that electricity is a huge part of your e{#blank#}2{#/blank#}  life. Basically, it keeps your home and school w{#blank#}3{#/blank#}  in winter and cool in summer. W{#blank#}4{#/blank#}  it, you would never be able to watch your favourite TV show or listen to your MP3 player. Have you ever i{#blank#}5{#/blank#} a world in which you can't turn on a light, a computer, or even use the phone? So electricity is important to us and we n{#blank#}6{#/blank#}  electricity. That's why it's time to rethink our relationship with this v{#blank#}7{#/blank#}  resource (资源) and think about h{#blank#}8{#/blank#}  we can do our part to use it wisely.

    Dream House in California is not a house for only one or two children. It's a house for many {#blank#}1{#/blank#}(kid). It's a family. It's the future.

    Many years ago, a little girl named Collin Rose{#blank#}5{#/blank#}(decide) that when she grew up, she would offer a warm home{#blank#}6{#/blank#}(介词) those sick and homeless children. When she grew up, she became{#blank#}7{#/blank#}(冠词)  nurse and made her dream come true. In November 2003, Collin Rose set up Dream House.

    Collin Rose's efforts have{#blank#}8{#/blank#}(encourage) many people to help sick and homeless children.

    "Every child should have a happy childhood. We may help make these children's lives{#blank#}9{#/blank#}  (good) than before. Your small help may{#blank#}10{#/blank#}(great) change their lives. No help is too small." Collin Rose said.

    Do you have any hobbies? If students don't have any interest e{#blank#}1{#/blank#} school work, they may become boring people. And that can influence their studies.

    Studying without relaxing isn't good for health. We can't get good g{#blank#}2{#/blank#} if we have bad health. We should do something we like. Some people like singing, taking photos and drawing p{#blank#}3{#/blank#}. Other people prefer collecting stamps, reading or shopping. I have a few hobbies, but my f{#blank#}4{#/blank#} is collecting stamps. I like it best because I can learn a lot from stamps.

    Some people collect stamps because they can m{#blank#}5{#/blank#} money from the stamps. But I am just i{#blank#}6{#/blank#} in collecting them and enjoy looking at them when I am free.

    Stamp collecting is becoming more and more p{#blank#}7{#/blank#} all over the world. I know an Australian boy and a French girl through the Internet. They both like collecting stamps. We show stamps to each other o{#blank#}8{#/blank#}. That is cool.

    In a primary school, a teacher asked her students what they wished to become when they grow up. There were several {#blank#}1{#/blank#} — a doctor, a teacher, a film-star and so on.

    One of the students gave a {#blank#}2{#/blank#} answer. This child said, "I want to be a television!" The teacher asked the child {#blank#}3{#/blank#} he had such a wish. He said, with his eyes full {#blank#}4{#/blank#} tears, "There is no one at home to watch me or care for me. Everyone sits around the television. If there is {#blank#}5{#/blank#} wrong with the TV, they give great attention to it and fix it at once."

    The loving teacher met the child's mother and {#blank#}6{#/blank#} about this with her. The mother said, "My husband is a very busy businessman. He {#blank#}7{#/blank#} has time to look after the child." "But what about you?" the teacher asked the mother. "What do you know about me? I'm the president of the women's club. I have {#blank#}8{#/blank#}many meetings and activities." The teacher now understood why the child {#blank#}9{#/blank#} lonely at home.

    "I think children want their parents to spend {#blank#}10{#/blank#} time with them." said the teacher.
