In China, the history of people planting and using bamboo can date back to as far as 7,000 years. As early as the Shang Dynasty, bamboo was being used in ancient people's daily lives. It was used for food, clothing, housing, transportation, {#blank#}1{#/blank#}(music) instruments and even weapons.

    The {#blank#}2{#/blank#}(apply) of bamboo in science and technology is thrilling. In 251 BC, Li Bing, in Sichuan, {#blank#}3{#/blank#}(lead) the local people in building the Dujiang Weirs(都江堰), the first irrigation network in the world, in which bamboo played {#blank#}4{#/blank#} important role. The world's oldest water pipe was also {#blank#}5{#/blank#}(make) of bamboo. During the Han Dynasty, the people in Sichuan {#blank#}6{#/blank#}(success) sank a 1600-metre-deep well with thick bamboo ropes. This technology did not spread to Europe {#blank#}7{#/blank#} the 19^th century, and it was by using the technology {#blank#}8{#/blank#} the Americans drilled the first oil well in Pennsylvania in 1859.

    In Chinese culture, bamboo is well-known as {#blank#}9{#/blank#} of the “four gentlemen” in plants. To many famous men, bamboo is a symbol of goodness and honesty. It is always closely related to people of positive spirits. Bamboo culture contributes to encouraging people to hold on when {#blank#}10{#/blank#}(face) tough situations.

    Zhang Jianxing has been walking through the ancient forests of the Shennongjia National Nature Reserve for over two decades to find the wild man. He will not give up until he {#blank#}1{#/blank#} (come) face-to-face with the creature. He began living in the mountain in 1994, after becoming {#blank#}2{#/blank#}(fascinate) by the wild man. Armed with a camera, he {#blank#}3{#/blank#} (constant) looks for clues of the creature's whereabouts, living off the land and {#blank#}4{#/blank#} (sleep) in abandoned homes and empty caves. To him, the wild man is a branch of science,{#blank#}5{#/blank#} that he has been studying for a very long time. So far, he has collected enough evidence of the wild man's {#blank#}6{#/blank#}(exist) —more than 100 hair samples and 3,000 photos of large footprints (脚印). He even came close to seeing it for himself no less than nineteen{#blank#}7{#/blank#} (time). However, most scientists regard it as nothing more than a legend {#blank#}8{#/blank#} there is a lack of concrete evidence. But Zhang Jianxing {#blank#}9{#/blank#}(convince) that he will one day find the wild man himself and prove the scientists wrong. To him it's just {#blank#}10{#/blank#} matter of time.

CCTV journalist succeeded in arousing a heated discussion among netizens by asking people whether they were happy. The responses {#blank#}1{#/blank#} the question were various, even some quite funny ones included. Although people {#blank#}2{#/blank#} (play) jokes on the answers, it did not take long {#blank#}3{#/blank#} they began to figure out the true meaning of happiness.

It is certain that people's views on happiness {#blank#}4{#/blank#}(affect) greatly by their own life experience. Unfortunately, too many people refer to being rich as happiness and there is no sign of a decrease in the number of those who are voluntarily at the mercy of wealth. Some people whose {#blank#}5{#/blank#} (intend) is to make big money appreciate being given any chance to increase their income, believing that is {#blank#}6{#/blank#} their happiness lies. Some are eager to inherit their parents' property, especially those {#blank#}7{#/blank#} are known as silver-spoon kids. Even worse, some would rather break the law {#blank#}8{#/blank#} (satisfy) their financial desire or seek their fortune {#blank#}9{#/blank#} (legal).

In my opinion, happiness is not about {#blank#}10{#/blank#} (pursue) wealth but about admiring the beautiful things in life. Therefore, live your life to the fullest and be happy.
