    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．

    The daughter, Susan, is good at growing flowers and keeping goldfish（养金鱼）．Every morning she gets up early．The first thing for her is to look at her flowers and goldfish．She likes them very much. When she is eighteen years old she goes to college（上大学）．She has to（不得不） tell her mother to look after（照顾）her flowers and goldfish．

    Her mother is too careless(粗心)．She is not good at growing flowers and keeping goldfish．

    By and by(慢慢的) the goldfish is dead（死了）,then the flowers. The mother has to write to （写信）her daughter to tell her all about her flowers and her goldfish．Susan is very sorry to hear that．She writes back (回信)to her mother a letter:“ Then what about my father?”

    When I was a kid, I did something really terrible. My father bought me two goldfish and named them "Iasc" and" Iasc Elie". He told me that meant "Fish" and "Other Fish" in Irish. To an eight-year-old child, the names seemed really boring.

    These boring names made me feel the goldfish were boring, too.  They did nothing more than swim around in their bowl. Sometimes, for fun, they would swim to the bottom of their bowl and dance around along the bottom, looking for interesting pieces of gravel.

    I tried many ways to make the goldfish more exciting. The most interesting thing was to see how long they could live out of the water. I took a fish out of the water with my hands and watched it gasping for air. Then I put it back in the bowl.  And then I would take them out of the water again, for longer and longer each time.

    Iasc and Iasc Elie started swimming towards the top of the water, not moving very much. Then they started floating on the top of the water. In other words, they were dead.

    I thought that bigger pets are more exciting, such as a cat and a dog. It would live longer than a goldfish, and then I kept a dog as my pet.

    One day, I walked into a stranger as he walked by me. "Oh, excuse me." I said. He replied with a smile and said, "Please excuse me, too. I wasn't watching out for you." We apologized(道歉) and went our own ways.

    Later that day, when I was cooking, my daughter was standing too close to me. When I turned to reach for some milk, I nearly knocked her over. "Move out of the way." I shouted. She walked away sadly. But I didn't feel like I had to apologize to her.

    While I was in bed that evening, my husband said to me, "Dealing with a stranger, you were polite, but with a daughter you love, you were unkind. Your daughter brought you some flowers that she picked herself this afternoon. You'll find them in the kitchen by the door. Have you seen the tears in her eyes?"

    I quietly went and knelt down by my daughter's bed. "Honey, I am so sorry." I said, "Are these the flowers you picked for me?" She said, "I found them by the tree. I picked them because they're pretty like you. I knew you'd like them especially the blue ones." I tearfully replied, "Sweetie, I'm really sorry for the way I acted today. I shouldn't have shouted at you." "It's okay. I love you anyway." she said as she kissed me on my cheek.

    If we can be polite to strangers, why can't we be kind to the ones we love?

    Doctor Carl was a very busy man. He always worked hard. He often forgot his families' birthdays. Yesterday afternoon he remembered(记得) it was his wife's(妻子的)birthday. He loved his wife. He wanted to give her a present. On his way home from hospital, he bought some beautiful flowers in a shop. When doctor Carl got home, he gave his wife the flowers and said, "Happy birthday to you, dear!" "It's April 20th today. I remembered your birthday this year. " Mrs. Carl laughed and said, "My birthday was the day before yesterday, but thank you all the same. Better late than never!"
