I was at the Indian grocery store with my cart totally full to check out. There was an African American man in his{#blank#}1{#/blank#}(sixty) behind me. I told him he could go before me{#blank#}2{#/blank#}he had just two items in his hand, and he was all smiles and added, as if{#blank#}3{#/blank#}(make) fun of me. “Thanks! Why don't you pay for my stuff too,” and laughed. I felt a little{#blank#}4{#/blank#}(embarrass)  and thought that the man had a wonderful sense of humor.

    I told the lady at the check out not{#blank#}5{#/blank#}(change) him. I said I would pay for him. He said, “No, no, no, I was just kidding.” And I{#blank#}6{#/blank#}(reply) with a smile, “Yes, yes your wish is heard. Please let me do it!”

    As we talked outside, he told me that the Indian herbs(草药){#blank#}7{#/blank#}he had bought{#blank#}8{#/blank#}(be) for his friend so I should take the money. I said to him, “It is good that it is not for you. Now you can pay it forward to somebody else.” He thanked me and promised he would.{#blank#}9{#/blank#} (eventual), I went home{#blank#}10{#/blank#}my car full of groceries and my heart full of warmth and kindness.

    Youth is a kind of wealth. It will gradually disappear{#blank#}1{#/blank#}time going by. What can we do to fulfill our youth?

    For one thing, it is to realize our value, and our dreams {#blank#}2{#/blank#}matters a lot.{#blank#}3{#/blank#} our dreams are, we must try hard to achieve them. When we are young, we are full of energy, and we have many{#blank#}4{#/blank#}(opportunity). We have good conditions in our lives, good memories, good understanding and so on. We should make the most of them to learn more.

    For{#blank#}5{#/blank#}, we should do as many things as possible. Of course, they must {#blank#}6{#/blank#} (rich) our lives, which can make it possible for us to gain many different experiences that are worth{#blank#}7{#/blank#}(remember) when we are old.

    Then when we are really old, and when we cannot move any{#blank#}8{#/blank#}(much), we can be proud of something{#blank#}9{#/blank#}(achieve), for we have lived our life to {#blank#}10{#/blank#} fullest.

    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.

    I wonder {#blank#}1{#/blank#}it is because I haven't been able to be outdoors for so long{#blank#}2{#/blank#}I have grown so crazy about everything to do with nature. I can well remember that there was a time    {#blank#}3{#/blank#}a deep blue sky, the song of the birds, moonlight and flowers could never have kept me spellbound. That {#blank#}4{#/blank#}(change) since I was there. For example, one evening when it was so warm, I stayed awake{#blank#}5{#/blank#}purpose until half past eleven in order to have{#blank#}6{#/blank#}good look at the moon by myself. But {#blank#}7{#/blank#}the moon gave far too much light, I didn't dare open a window. Another time five months ago, I happened to be upstairs until the window had to{#blank#}8{#/blank#}(shut). The dark, rainy evening, the wind, the thundering clouds held me entirely in{#blank#}9{#/blank#}power; it was the first time in a year and a half that I {#blank#}10{#/blank#}(see) the night face to face...

    Qiang Shuping was so busy making cloth shoes{#blank#}1{#/blank#} she didn't even rest during the Dragon Boat Festival holiday. The woman from Baipu County, Jiangsu Province, {#blank#}2{#/blank#} (make) shoes since she was 19 years old, and this year marks her 31^st year making cloth shoes.

    She spends the entire day in her tiny studio, which {#blank#}3{#/blank#}(measure) less than 10 square meters altogether, filled with cloth shoes in{#blank#}4{#/blank#}(variety) stages of completion.

    Nowadays, many stores make cloth shoes{#blank#}5{#/blank#} (use) machines, but Qiang sticks to the technique of making shoes entirely {#blank#}6{#/blank#} hand. She says the shoes {#blank#}7{#/blank#} (produce) by the machine are not of the same quality as handmade ones. The handmade cloth shoes are more durable and comfortable, {#blank#}8{#/blank#}(soft), and absorb sweat better.

    Some people buy cloth shoes out of nostalgia(怀旧), while others trust {#blank#}9{#/blank#}(they) quality. Making shoes isn't a profitable job, but Qiang still insists as she wants to preserve the craft and pass it down to the younger generation.

    Handmade cloth shoes are also called qiancengdi (shoes with a thousand layers), {#blank#}10{#/blank#} can date back to the ancient Zhou Dynasty. In 2009, the making technique of qiancengdi was listed as the national intangible cultural heritage.
