Many of us were raised with the saying "Waste not, want not.” None of us,{#blank#}1{#/blank#}, can completely avoid waste in our lives.

    Any kind of waste is thoughtless. Whether we waste our potential talents, our own time, our limited natural{#blank#}2{#/blank#}（资源）,our money, or other people's time, each of us can become more aware and careful. The smallest good habits can make a big {#blank#}3{#/blank#}.  It's a good feeling to know in our hearts we are doing our{#blank#}4{#/blank#}in a world that is in serious trouble.  By focusing on {#blank#}5{#/blank#}（节省）oil, water, paper, food, and clothing, we are playing a part{#blank#}6{#/blank#} cutting down on waste.

    We must keep reminding {#blank#}7{#/blank#}（自己）that it is easier to get into something {#blank#}8{#/blank#}it is to get out of it. Actually, severe damaged {#blank#}9{#/blank#}to our land is fairly recent in the history of our evolution.  It's time for us to{#blank#}10{#/blank#}no to waste so that our grandchildren's children will be able to develop well.  We can't solve all the problems of waste, but we can encourage mindfulness.

    Waste not！

    When I was a child in 1970s, my family was very poor, just{#blank#}1{#/blank#} other average families in the countryside. The second-hand clothes and rain leaking roof of old house became part of my memory. However, the worst{#blank#}2{#/blank#} (impress) is that I was feeling hungry all the time. Sometimes hunger bit me so severely {#blank#}3{#/blank#} I regarded dried sweet potato slices as delicious snack. At that time, my dream was getting enough to fill my empty stomach.

    In the early years of 1980s, with the reform and opening-up policy {#blank#}4{#/blank#} (carry) out, the children's dream came true. And then{#blank#}5{#/blank#}dream became clear and clear in my mind, I must try my best to escape out of my poor and backward hometown. I worked{#blank#}6{#/blank#} (hard) at my study than most of my classmates, and, after lucky{#blank#}7{#/blank#} (succeed) in the national college entrance examination, I realized my dream again: after graduation, I became a citizen working in a city. As the first college graduate out of a remote village, I set an example for my folks.{#blank#}8{#/blank#} came to realize that schooling is a good way to change one's fate. In the{#blank#}9{#/blank#} (follow) years, there were fewer dropouts and more college graduates in my village, of{#blank#}10{#/blank#} I am proud even today.

    Christmas is the most important festival in the western world. It{#blank#}1{#/blank#}(fall) on December 25^th . When my mother and I stayed in America, we{#blank#}2{#/blank#}(invite) by one of my mother's friends to observe Christmas with an American family. We bought some{#blank#}3{#/blank#}(present) for our American friends on our way{#blank#}4{#/blank#} their house.

   They had prepared different kinds of gifts for their family and guests when we got to their house, such as Christmas candles, cakes, cards, little toys, biscuits and so on. A Christmas tree was placed in{#blank#}5{#/blank#} corner of the brilliant hall.{#blank#}6{#/blank#} beautiful it was! We were impressed by these. We had a big meal. After dinner, they told us some interesting stories about Christmas.

    We learned that Christmas had something to do with Jesus. We went to bed at midnight{#blank#}7{#/blank#} we knew the Santa Claus was not true, we were still waiting for the Santa Claus{#blank#}8{#/blank#}(bring) us presents. And we received many beautiful presents the next morning.

    This Christmas was really {#blank#}9{#/blank#}(forgettable). Not only {#blank#}10{#/blank#} I have a good time, but also I knew something about foreign culture.

    I love natural science, which came from my curiosity in nature. From {#blank#}1{#/blank#} early ago, I caught frogs and insects in the nearby woods. I explored the cool streams {#blank#}2{#/blank#} (run) through the woods and searched for fish living in the water.

    As I grew up, my interests expands around subjects in school, particularly {#blank#}3{#/blank#} biology, chemistry and physics in high school. These interests were increased with more time {#blank#}4{#/blank#} (spend) in the deserts of Arizona. The desert was not totally new to me, since I {#blank#}5{#/blank#} (visit) relatives in Phoenix several times before moving there. However, exploring the desert on my own was new. I checked under every rock and bush looking for {#blank#}6{#/blank#} (sign) of life. I found many incredible animals. Once I happened to discover {#blank#}7{#/blank#} (poison) snakes under a rock. I was very sacred. However, I {#blank#}8{#/blank#} (eventual) grew to be cautious of them and now snakes are my favorite study subject.

    I am now an ecologist. I have done research in deserts, forests, streams and lakes. Finding new species still {#blank#}9{#/blank#} (excite) me. I am glad to have a strong inquisitiveness (求知欲) in the natural world. My hobby and curiosity make me {#blank#}10{#/blank#} I am now.
