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!

    If you have a brother or a sister, you already know you are different from each other. You live together in the same house and have the same parents. {#blank#}1{#/blank#}． Why is this? One possible reason is the way your parents treat you.

    First—born children receive all the attention from their parents. Most families have much more photos of a first—born than any other child. Parents give them more responsibility（责任）.{#blank#}2{#/blank#}． As a result, first—borns are often responsible, hard—working and serious. They often want to do well at school and work.{#blank#}3{#/blank#}． For example, Gorge Bush, George Washington, and Lyndon Baines Johnson are all first—born.

    When a second child arrives, parents are more relaxed. The second child is allowed to be more independent. But he also has to compete with the first—born for the parents' attention and love. These children often choose different sports and hobbies to show independence.{#blank#}4{#/blank#}． They are often adventurous（爱冒险的）, fun—loving, and outgoing, but can be jealous（好嫉妒的）and get angry easily.

    The youngest child is the happiest. He has fewer responsibilities and more freedom. These children do not feel pressure to do well at school and work, but have to be creative to get their family's attention.{#blank#}5{#/blank#}．So, many famous talk—show hosts and comedians were born last.

    A few days ago, I was walking down the street when I met a group of students in uniforms. I was shocked to see that the girls' skirts were very short and they were wearing a lot of make-up. The boys looked very untidy. Their shirts were dirty and some of them even had their shirt fronts open. I noticed that some of the students had their ears and noses pierced, which should not be allowed at school.

    And the other day, I was on the subway when I saw some boys wearing uniforms of the same local school. Instead of sitting quietly, these boys kept making noises and saying dirty words. All the other passengers were looking at them and wondering how it was possible for students like these boys. They were really showing a bad image(形象) of their school, which was shameful.

    I am a mother of two teenagers of the same school. After seeing those boys and girls, I am worried if my children also behave like this. I don't know about it. Do students in this school know what is allowed when they are wearing the school uniforms? I think the school should be stricter with the students, and I think all the students should be taught how to be polite.

    Car Free Day encourages drivers to give up their cars for a day to protect the environment. People from around the world get together in the streets to remind the world that we don't have to; accept the society full of cars. It started from France in 1998. Because of the air and noise pollution, some French young people wanted a day without cars. On September 22nd, people in 35 cities in France didn't use their cars. They went to work or school by bike, bus or on foot. After that, September 22nd became Car Free Day. The first Car Free Day in China was in Chengdu in 2001. The slogan(口号) for the day is "If we, drive for one less day, we can have one more nice day."

    Organized activities are held in many cities on Car Free Day. In Brussels, Car Free Day shall be valid(有效的) for everybody except persons with a special permit(许可证),but they have to slow down to the speed of 30 kilometres per hour. The public transportations are encouraged. The streets are open only to walkers, bicycles and buses from 7:00 a.m. to 7:00 p.m. In Beijing, it asks drivers to leave their cars at home for one day each month and walk or ride a bike to work. More and more people are taking part in the activity. In the first quarter of this year, Beijing only had 52 blue sky days, and you may see haze almost every day! We must do more for Car Free Day as a Beijing driver said, "We may not change the weather, but we can choose not to drive."

    But we do not want just one day and then a return to "normal" life. We should go on with Car Free Day.
