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?

    I went through some difficult times, dealing with the pressures of growing up. I found it hard to communicate with my mother. Relations between us became difficult.

One day, I ran away from home and stayed away for many hours. When I returned home at night, I saw all the pain, anger and disappointment on my mother's face. ①      . We agreed to have breakfast together the next morning. It was a turning point in both of our lives and our relationship.

We decided to go to a restaurant. On our way to the table I noticed my mother had two notebooks. I asked her what they were for. She explained to me that sometimes it was easier to write down our feelings rather than talk about (A) them. We would write down our feelings in the form of a letter. It could be as long or as short as we wanted.

    Our first topic was “Why I'm so angry?” I wrote a half page, and my mom filled up nearly three pages. (B) I watched tears run down her face as she wrote. I never realized anyone could hide so much anger. After we finished writing, we exchanged our notebooks. As soon as I started reading my mother's words, I began to cry and so did she. When we finished reading, we discussed our feelings. ②      . Our talk helped me realize so many things I had never thought of before, not only about my mother but also about other people.

     My mother and I continue to use our notebooks as a way of communicating our anger and worries, and our happiness as well. We know that no matter how we feel about each other, our notebooks are a safe place to express our feelings. We have come to an agreement that at the end of each letter we write, “I love you.”

    Many people like to travel by plane, but I don't. The airport is usually far from the city. You have to get there early and wait for hours before the plane takes off and it is often late. You can't open the window. You can't choose the food. Planes are fast but it still takes hours to get out of the airport and into the city.

    I like traveling by train. I think trains are safe. Railway stations are usually in downtown. When you are late for a train, you can catch another. You can walk around in the train and open the windows. You can see many interesting things on your way. I know it takes a little more time. I also like cars. You can start your journey when you want to, and you don't need to get to a railway station or a bus stop. Also you can carry many things with you in a car. But sometimes there are too many cars on the roads.

A. Have him or her lie with feet lifted a little.

B. Wash the bite area with soap and water.

C. Pinch (捏) the lower part of the nose for at least 10 minutes.

D. Use an ice pack（袋）.

E. Clean the person's face with a cool cloth.

    What should we do if one of our classmates suddenly falls ill or gets hurt? Here are some steps you should follow. But always remember to look for medical care after first aid(急救)if the wound is serious.

    Broken bones(骨头): Take away clothing from the wound{#blank#}1{#/blank#} Don't move the hurt body part while waiting for the doctor to arrive.

    Animal bites(咬伤):{#blank#}2{#/blank#}Pack （拧紧）the wound with a clean cloth if it is bleeding（出血）. If the bleeding has stopped, cover the area with a bandage and take the person to the hospital. Make sure you remember what kind of animal it is so the doctor can find the right way to treat him or her at once.

    Fainting(昏厥):{#blank#}3{#/blank#} Don't move the body if you think there might be wounds from the fall. Make sure he or she can breathe and let in fresh air.{#blank#}4{#/blank#}

Nosebleeds(流鼻血): Have the person sit up with his or her head tilted(倾斜)forward a little. Do not have the person tilt his or her head back because this may cause heavy breathing or coughing.{#blank#}5{#/blank#}

    Donna Reid had just finished her training as a children's doctor. A famous research hospital in New York had offered her a job with good pay. And her boyfriend, Tony, had a clinic in their hometown and hoped she could work with him. At the same time, a small hospital, Backwoods Hospital, in a very poor area had also offered Donna a position. Now it was time for her to decide where to work.

    Dad: Donna, that research hospital in New York has a good reputation for children's medicine. Some of the best children's doctors in the country work there and you can learn a lot from them.

Mom: Yes, I agree it's a good hospital and the pay is good, too. But, that's not the point.

    Dad: Then what's the point?

Mom: It's in New York, too far away!  Let me tell you what, dear Donna. Tony's clinic is just several blocks away. You don't need to travel far if you work there. Tony is a nice young man and I guess you'll get married soon.

    Dad: Ha! It's hard enough to live with a husband or wife. Working with them, too? That's a choice for trouble. Well, Donna, what do you think?

    Donna: I'm thinking about accepting the offer from Backwoods Hospital.

    Dad: But Donna, look at their offer! You'll be on call six days a week, 24 hours a day. That's really a hard job.

    Mom: Oh, Donna, the pay is another problem.

    Donna: It isn't a dead-end job, Mom and Dad. But anyway, I didn't __.

    Dad: No? Then why did you become a doctor?

    Donna: I want to help people. You know that. And Backwoods serves a very poor and needy population. Backwoods, here I come!
