When I was a university student, I {#blank#}1{#/blank#}(attract) by the Chinese. So I got a job as a teacher in Wuhan three years ago.{#blank#}2{#/blank#} (think) back, I realize it was the students I met in the first year and Chinese university life in general {#blank#}3{#/blank#}gave me the deepest impression.

    During my school days, I would rarely give up my spare time to any activity {#blank#}4{#/blank#}(connect) with study. Unless exams were approaching, my weekends were devoted to having fun or perhaps a part-time job. My Chinese students,{#blank#}5{#/blank#} the other hand, seemed to spend their entire waking hours studying. I understand that competition in Chinese universities is extremely fierce. Nonetheless, their energy and motivation put {#blank#}6{#/blank#}(I) to shame.

    My first year in China was also my first year as a teacher. It was both challenging {#blank#}7{#/blank#}rewarding. One thing I know for certain is that my year in Wuhan changed me for the {#blank#}8{#/blank#}(good). Thanks to the politeness and {#blank#}9{#/blank#}(warm) of Chinese students, I overcame my fear of speaking in public and became more self-confident. Most {#blank#}10{#/blank#}(important), I met dozens of nice people and made many excellent friends.

    Marry of us wake up feeling{#blank#}1{#/blank#}(tire) in the morning. Many of us ignore the problem as the day goes on,{#blank#}2{#/blank#} (forget) that it might have a{#blank#}3{#/blank#}(danger) effect. Society even glorifies “burning the candle at both ends” as{#blank#}4{#/blank#}sign of our devotion to work and family.

    Believe it{#blank#}5{#/blank#}not, all this bad sleep has far-reaching consequences. We just do not give ourselves enough chances to sleep. A survey of over 74,000 people found 35 percent reported sleeping less than seven hours daily{#blank#}6{#/blank#}average. Furthermore, the amount of sleep{#blank#}7{#/blank#}(change) greatly over the past 15 years.

    This lack of sleep can lead of many serious{#blank#}8{#/blank#}(problem). One study found that{#blank#}9{#/blank#}(simple) limiting yourself to six hours of sleep a night for two weeks had similar effects to staying up all night the night before,{#blank#}10{#/blank#}could make you perform poorly on a timed attention task.

    As Victor Hugo once said, “Laughter is the sun that drives winter from the human face”, and up to now nobody {#blank#}1{#/blank#}(be) able to do this better than Charlie Chaplin. He brightened the lives of Americans and British through two world wars. He made people laugh at a time {#blank#}2{#/blank#} they felt depressed, so they could feel more content {#blank#}3{#/blank#}their lives.

    Charlie was born in a poor family in 1889. His parents were both poor music hall performers. You may find it astonishing that Charlie {#blank#}4{#/blank#}(teach) to sing as soon as he could speak and dance. Such training was common in acting families at this time,{#blank#}5{#/blank#}(especial) when the family income was often uncertain. Unfortunately his father died, {#blank#}6{#/blank#}(leave) the family even worse off, so Charlie spent his childhood {#blank#}7{#/blank#}(look) after his sick mother and his brother. By his teens, Charlie had, through his humour, become one of the most popular child{#blank#}8{#/blank#}(actor) in England. He could mime and act the fool doing ordinary everyday tasks. No one was ever bored watching him－his subtle acting made everything entertaining.

    With time{#blank#}9{#/blank#}(go) by, he began making films. He grew more and more popular as his charming character, the little tramp, became known throughout {#blank#}10{#/blank#}world.

    When foreigners negotiate, or register in certain areas of China, they may be {#blank#}1{#/blank#}(surprise) at Chinese's special fondness and preference for seals. To Chinese, seals are an art of deep cultural roots, {#blank#}2{#/blank#} combines the essence of both calligraphy(书法) and sculpture and inspires generations to study, to appreciate and to collect.

    It is believed that seals came out as early {#blank#}3{#/blank#} 8,000 years ago after our ancestors could make pottery wares(陶瓷)and had private property. They were assumed to make marks on {#blank#}4{#/blank#}(they) own possessions to prevent them from being stolen. When the first dynasty {#blank#}5{#/blank#}(found),the king began to use seals to empower(授权)and to show lordly credits. Only the king's special seal was then called "Xi", {#blank#}6{#/blank#}(represent) the highest authority. The first emperor of China, Qin Shi Huang, had his "Xi"{#blank#}7{#/blank#}(make) out of the invaluable and beautiful jade "Heshi Bi".

    Then the local governments also needed seals for {#blank#}8{#/blank#} same function. Meanwhile, private seals were carved in a variety of lucky {#blank#}9{#/blank#}(character)and vivid animal patterns.{#blank#}10{#/blank#}(gradual). the sphragistics (印章学) came into being.
