In many people's opinion, man's first real invention,{#blank#}1{#/blank#}is also one of the most important inventions in history, is the wheel. All transportation and every machine in the world depend{#blank#}2{#/blank#}it. The wheel is the{#blank#}3{#/blank#}(simple) yet perhaps the most remarkable of all{#blank#}4{#/blank#}(invention) because there are no wheels in nature.{#blank#}5{#/blank#}, then, did man come to invent the wheel? Perhaps some early hunters found that the body of {#blank#}6{#/blank#}heavy animal could be rolled through the forest on logs (圆木) more{#blank#}7{#/blank#}(easy) than they could carry it. However, the logs{#blank#}8{#/blank#}them) weigh a lot.

    It must have taken a great prehistoric thinker to imagine two thin slices of log connected, at their centers by a string stick. This would roll along just {#blank#}9{#/blank#}the logs did, yet be much lighter and easier{#blank#}10{#/blank#}(handle). Thus the wheel and axle came into being and with them the first carts.

    A young man in Wuhan, Hubei Province has become the latest Internet sensation after a video showing his heart-warming act on a subway train went viral on social media {#blank#}1{#/blank#} (recent).

    In the video, the man can be seen {#blank#}2{#/blank#} (hold) his mobile phone in his hand after falling asleep on a Metro, with a message in large font on the screen which reads, “Please wake me if you need my seat.”

    The video {#blank#}3{#/blank#} (record) by a fellow passenger who posted it on Weibo, The video, {#blank#}4{#/blank#}length was just 7 seconds, has been viewed more than 19 million times in just two days. Chinese netizens were greatly touched by the young man's act and applauded him for his kind {#blank#}5{#/blank#} (behave). A web user even commented, “I only needed 7 seconds to fall {#blank#}6{#/blank#}love with this young man.

    The humble man {#blank#}7{#/blank#} (refuse) an interview invitation after becoming an Internet star and said that he just did {#blank#}8{#/blank#}he felt he should. In a Weibo post, he thanked netizens for {#blank#}9{#/blank#} (they) love and praise. He said he would always fall asleep when he had nothing to do on the train but worried others may need the seat, so he got {#blank#}10{#/blank#}idea of making a message on his phone screen.

    In my opinion, we should try our best {#blank#}1{#/blank#}(realize) our goals even though {#blank#}2{#/blank#}is little hope. The efforts seem to be the lights in the darkness, leading the way to hope and success. I used to be {#blank#}3{#/blank#}shy girl in my primary school. I was weak in English at that time, especially for {#blank#}4{#/blank#}(speak) English. So I was afraid to answer the teacher's questions during English classes. After I entered my dream middle school. Something {#blank#}5{#/blank#}(change). I started to read many {#blank#}6{#/blank#}(interest) English stories and my English teacher was patient to help me a lot. I studied hard in class and practiced by watching English films and listening to English songs in my free time. Little {#blank#}7{#/blank#}little, I found {#blank#}8{#/blank#} more and more interesting to learn English. I could even talk with my classmates {#blank#}9{#/blank#}(fluent) in English and I was not shy any more. At last, I got high grades in English and I had {#blank#}10{#/blank#}(confident) to do it better in the future.

    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 measures less than 10 square meters altogether, filled with cloth shoes in {#blank#}3{#/blank#} (vary) stages of completion.

    Nowadays, many stores make cloth shoes {#blank#}4{#/blank#}(use) machines, but Qiang sticks to the technique of making shoes entirely {#blank#}5{#/blank#} hand. She says the shoes {#blank#}6{#/blank#} (produce) by the machine are not of the same quality as handmade ones. The handmade cloth shoes are more durable and comfortable, {#blank#}7{#/blank#} (soft), and absorb sweat better.

    Some people buy cloth shoes out of nostalgia(怀旧), while {#blank#}8{#/blank#} trust their quality. Making shoes isn't {#blank#}9{#/blank#} 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.
