How airplanes fly?

People {#blank#}1{#/blank#} (try) for a long time before they invented a {#blank#}2{#/blank#} (success) "flying machine". Now there {#blank#}3{#/blank#} (be) so many {#blank#}4{#/blank#} (plane) in the sky.

    An airplane {#blank#}5{#/blank#} (fly) because of the upward force(力量) of {#blank#}6{#/blank#} (move) air against its wings(翼). To get that moving air, it needs something {#blank#}7{#/blank#} (push) it forward—like a motor-driven propeller(螺旋桨) or a jet engine(喷气发动机). You can fly a kite if there  {#blank#}8{#/blank#} (be) enough wind to hold it up. An airplane is like a kite with such force!

    More and {#blank#}9{#/blank#} (many) young people are getting to like making model planes now. How about you? Are you interested in it after {#blank#}10{#/blank#} (read) this article?

    This week, our topic is pollution. What are the answers to all of our pollution problems? We asked two experts to give their views.

    ◇Forest Smith is a member of Green First, an environmental group.

    Our future on the Earth looks very bad. We are dumping waste on our land. We can't breathe the fresh air. The sea is polluted too.

    I visited some relatives recently in a small village. They grow their own food and cycle everywhere. They are not wealthy, but they are happy and healthy.

    We must close the factories producing useless products. That will reduce rubbish and air pollution. We must recycle more, give up all cars, and improve public transport.

    A big problem is overpopulation in big cities. We must give up big cities and factories, and go back to a simple way of life.

    ◇John Green is a scientist at a university.

    Things are not as bad as Forest says. We'll have a bright future. We don't need to give up cars but we need to invent better, cleaner engines.

    This won't stop the problem of traffic jams. So we need better public transport. We should also recycle more.

    But some things are getting better. My sister returned last month after living abroad for five years. She said, “Our old neighbourhood doesn't look the same as before－it is cleaner and greener now.”

    In a word, science has brought many improvements to our life.

    In most parts of the world, many students help their schools make less pollution(污染). They join “environment(环境) clubs ”. (1)In an environment club, people work together to make our environment clean. Here are some things students often do.

    No garbage(垃圾) lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags and the bags can be used again. If the classes make the least garbage, we will report them to the whole school!

No car day. On a no car day, nobody comes to school in a car—not the students and not the teachers! Cars give pollution to our air, so remember: Walk, jump, bike or run. Use your legs! It's lots of fun!

    Turn off the water! Did you know that some toilets(厕所) can waste(浪费) 20 to 40 m³ of water an hour? In a year, that would fill a small river! In environment clubs, students mend(修理) those broken toilets.

    We love our environment. (2)Everyone should take _______ to make our environment ______. Let's work together.

    Steve visits the nursing home near his house two afternoons each week. On one of those days, he reads to his friend Martin. On the other afternoon, he plays cards and talks with Mrs Johnson. Steve enjoys spending his extra time this way. He is a volunteer. A volunteer is a person who helps another person or has a job for which he or she does not get paid. A volunteer donates his or her time for free.

    Everyone else in Steve's family is also a volunteer. Steve's mother Mary volunteers one afternoon each week at the local hospital. She talks to patients, delivers flowers, and helps the nurses with odd jobs. Steve's sister Gina volunteers two afternoons each week at the museum. She welcomes visitors and answers their questions. Steve's father David is also a volunteer. He is a volunteer fire fighter for the town in which they live.

    Steve's family thinks volunteering is very important. Steve's parents think being a volunteer helps to teach values. Steve and his sister learn how to be kind and respect other people.

Steve's family does volunteer work to give something back to the community. They want to help people who are not as fortunate as they are.

    When you hear the name Hollywood, you probably think of excitement, lights, cameras and movie stars. Famous actors are not the only important people in the entertainment business. Directors and producers are important, too. Today, Hollywood is full of producers and directors. And it is one of the tourist destinations in America.

    In 1911 the small, peaceful village of Hollywood in California voted to become part of Los Angeles. Today, over 100 years later, this village has grown into the home of one of the best-known industries in the world- the American film industry.

    With this growth, came many well-known symbols. There is the famous Hollywood sign which stands above the hills of the town. The first sign was built in 1923. Then there is Hollywood Hall of Fame, where great actresses, actors and directors leave their footprints or handprints. Norma Tallmadge was the first actress to do this in 1927. But most famous of all are the Oscar Academy Awards(奥斯卡颁奖). In March of every year a number of actresses, actors and directors wait nervously to find out if they have won an "Oscar". The 85th Oscar Academy Awards was held on February 25, 2013, in Los Angeles. Ang Lee(李安),a Chinese director won the best director again. It was his second time to win an "Oscar".

    Nowadays it becomes more and more common for films to be made away from Hollywood itself, but it remains the home of films, and thousands of hopeful young actresses, actors, writers and directors still come to "the Dream Factory" every year. But not all Hollywood dreams have been happy ones- as one actress, who later died tragically(悲惨地), said," Hollywood is a place where they will pay you 500 dollars for a kiss, and 50 cents for your soul.
