    Some of the greatest problems we face today are the destruction (破坏) of our environment． Brown clouds, polluted water, endangered wild animals．．, these problems seem so huge．

    So my family does what we can． We take cloth bags to stores instead of using plastic bags． We walk where we don't have to drive．．．

    But does it do any good? When I am the only one in line at the market with cloth bags, am I doing any good? Does my walking to stores make any real difference to the world?

    I recently learned something about flamingos (火烈鸟) which like to get together in groups of a thousand or more． Every year, when the time comes for migration (迁徙), a few of them first takeoff from the lake． But none of the others seem to notice, so the small group returns．

    However, the next day they try again． This time few more fly along with them, but most of them still pay no attention, so they return again． They try for several times． Every time a few more birds join in but, since the thousands of others still take no notice, the great migration plan is once more stopped．

    Then one day something changes． The same small group of birds once again starts flying and a small number more join in just as before, then more． Finally, they all take flight and the migration really begins．

    What a spectacular sight it must be—thousands of flamingos taking off into the sky at once!

    A few can make a difference． Even if you're the one to take the first step, and continue trying, others will someday take notice and together we will solve even our greatest problems．

B

    Once upon a time, a girl called Goldilocks went into the forest and picked some flowers. She saw a little house and she knocked on the door. There was no one there, so she entered the room. On a table there were three bowls with some food in them. First, she finished the food in the smallest bowl. Next, when she sat down, she destroyed the smallest chair. Finally, she walked into the bedroom and was soon asleep in the smallest bed.

    Goldilocks didn't know the little house was three bears' home. When the three bears returned home, they didn't notice Goldilocks at first. But finally they saw her. When Goldilocks opened her eyes and saw them, she was very frightened and hurried away without her basket. She didn't return again.

    Hello, My name is Dale. I'm 13 years old. This is a photo of my family. Look! This is my father. His name is Tim Brown. He is 45 years old. This is my mother Alice. She is 43 years old. I have a sister and her name is Gina. She is 11 years old. I look like (长得像)my mother and Gina looks like my father. All my family are in the same school. My parents are teachers. They are friendly (友好的) to the students, so the students love them very much. My sister and I are students and we love our school.

    I' m ready to do my first jump 10 months after a skydiving (特技跳伞) accident. I can't wait! That accident almost killed me and it made me stay in hospital for half a year. During the boring long days, I didn't feel glad to be alive. I was wondering how I could live without my favorite sport.

    It all started one evening after a nine-to-five day. I was sitting on the sofa when an ad (广告) came on the television. "Try skydiving," it said. The next day, I went to the skydiving school in my town. At the end of the day's lessons, I knew I found the fight sport for me.

    I will never forget my first jump. Five of us walled to the runway and got into a plane. I was scared, but the others were tailing and joking, and I started to feel a little relaxed. It was a beautiful, cloudless day and the sun was just going down. Soon it was time to jump. As I jumped from the plane, I shouted. But then everything became quiet. It was the most wonderful four minutes of my life.

    From the first jump, I was hooked. I started spending all my free time skydiving . It became my reason for living. Things were going really well. Then an accident happened on my 104th jump. I broke my both legs, right arm and nose. I stayed in hospital for six months, but I still couldn't forget skydiving.

    My mother couldn't understand why the only reason I wanted to get better was to go skydiving again. But for me, skydiving is life, and life is skydiving.

    Ray's wedding had gone off smoothly. Everyone seemed to have had a good time. A few people had too good a time; they went home with designated (指派的) drivers. All evening, the gift table remained unguarded. Who would steal anything, Ray thought. He had never heard of such a thing happening at a wedding. But his best friend Aaron said there was a first time for everything. He strolled out regularly from the inside festivities (庆祝) to check on the gift table, making sure no one suspicious was hanging around it.

    Ray and Julia went on a 3-week honeymoon to Italy right after the wedding. When they got back, they opened all the gifts and sent out thank-you notes. But there was one problem. A married couple that used to be good friends had apparently given nothing. This surprised Julia, because Walt and Mary said they were thrilled to be invited. And, they actually seemed to have had a great time at the wedding. Frankly, Ray didn't even care if they hadn't given a gift. He just needed to know whether to send a thank-you note. Ray called Aaron. Aaron said maybe Walt had left an envelope on the gift table like Aaron had. "Yes, but we got your envelope with the cash inside," Ray said. "Maybe my envelope looked too thin, and some thief thought Walt's envelope looked nice and fat."

    Aaron asked Ray if he had looked everywhere for Walt's gift. Had he called up the wedding site to see if anything had been left behind? Ray said that he had looked everywhere and made a lot of calls that were fruitless.

    Ray didn't know what to do. If he sent Walt and Mary a thank-you note for a gift they hadn't given, they would be insulted. If he didn't send them a thank-you note for a gift they had given, they would get angry.

    "What would you do?" Ray asked. Aaron said he would call Walt up and tell him the problem.

    "You can't go wrong with simply being honest," Aaron said.

    "Oh, yes, you can," Ray contradicted (反驳) him. "Sometimes it's best to let sleeping dogs lie." But he thought about it, and finally decided that Aaron was right. He called Walt and told him the problem. Walt said that yes, he had given an envelope. In fact, the envelope contained $500 cash.

    "$500?!" Ray asked. "That's a lot of cash, Walt!" Walt admitted that it was, but he had gotten a fat raise (加薪) early that year and Ray's was the only wedding he'd been to in quite a while. Ray thanked him very much, and apologized sincerely for someone stealing Walt's generous gift. Walt told him that it was "only money".

    When Ray told Aaron about Walt's gift, Aaron laughed. "The only thief at the wedding was Walt! I quit playing cards with him last year because I caught him cheating. And it was only a $10 pot! I'm sure I told you about that."

    "Yes, you did tell me," Ray said. But, of course, he had to send Walt a thank-you note anyway.
