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.

    Chinese Kung fu is a{#blank#}1{#/blank#}(tradition) Chinese culture. It is probably one of the earliest sports that use both{#blank#}2{#/blank#}(strong) and brain.

    The theory of kung fu is based{#blank#}3{#/blank#}classical Chinese philosophy. Over its long history it has developed as a unique combination of exercise, practical self-defense, self-discipline, and art. It can date back to ancient times{#blank#}4{#/blank#}people used sticks to fight against wild animals and they gradually{#blank#}5{#/blank#}(gain) experience in self-defense.

    Chinese kung fu is a large system of theory and practice,{#blank#}6{#/blank#}(combine) techniques of self-defense and health-keeping. In sports like track and field and boxing, an athlete{#blank#}7{#/blank#}(usual) has to retire from full participation in his 30s. That is because{#blank#}8{#/blank#}(injury) suffered during years of active sport participation at a young age affect our ability to continue exercising in later life. In Chinese kung fu, however, a difference{#blank#}9{#/blank#}(make) between "external"(外部的) and "internal"(内部的) kung fu. It's said that in external kung fu, you exercise your muscles, bones and skin while in internal kung fu, you train your spirit, qi and mind. So the external body weakens later in life, but on{#blank#}10{#/blank#}contrary, internal kung fu continues.

    Our trip was fantastic. Every driver and every tour guide{#blank#}1{#/blank#}(be) knowledgeable, and tried to meet our interests and wishes. As Erich practiced his Chinese with them, they responded in English. The locations{#blank#}2{#/blank#}(select) by us were most interesting. Although I am not used{#blank#}3{#/blank#}sub-zero weather,{#blank#}4{#/blank#}was Harbin that I would recommend to any travel lover because it was so unique. All of the sights were unique with so much to offer. If we hadn't gone on the trip to Harbin, we would {#blank#}5{#/blank#}  (have) no chance to enjoy all the sights there then.

    The hotel accommodation was comfortable. We had one experience when the power went off in a block that contained our hotel, but{#blank#}6{#/blank#}(fortunate), the power was restored within a few hours. The restaurants were as unique as the areas{#blank#}7{#/blank#}we went and a Chinese cuisine was enjoyed by all four. Our guides made certain that our meal was ready and to our{#blank#}8{#/blank#} (tasty).

    If our son and daughter-in-law stay another year, we will discuss a repeat visit next year around the same time. As Erich and Caitlin are students at an in ternational university in Tianjin, the trip revolves around their academic schedules. We are quite pleased with the nice{#blank#}9{#/blank#} (serve) provided by the relevant people {#blank#}10{#/blank#}(show) our friends and family we have taken lots of photos and videos.

    A 90-year-old has been awarded "Woman Of The Year" for {#blank#}1{#/blank#} (be) Britain's oldest full-time employee-still working 40 hours a week. Now Irene Astbury works from 9am to 5pm daily at the pet shop in Macclesfield, {#blank#}2{#/blank#} she opened with her late husband Les. Her years of hard work have {#blank#}3{#/blank#} (final) been acknowledged after a customer nominated (提名) her to be Cheshire's "Woman Of The Year".

    Picking up her "Lifetime Achievement" award, proud Irene {#blank#}4{#/blank#} (declare) she had no plans {#blank#}5{#/blank#} (retire) from her 36-year-old business. Irene said, "I don't see any reason to give up work. I love coming here and seeing my family and all the friends I {#blank#}6{#/blank#} (make) over the years. I work not because I have to, {#blank#}7{#/blank#} because I want to."

    Granddaughter Gayle Parks, 31-who works alongside her in the family business-said it remained unknown as to who nominated Irene for the award. She said, "We don't have any idea who put grandma forward. When we got a call {#blank#}8{#/blank#} (say) she was short-listed, we thought it was {#blank#}9{#/blank#} joke. But then we got an official letter and we were blown away. We are so proud of her. It's {#blank#}10{#/blank#} (wonder)."

Comets are among the most beautiful and interesting {#blank#}1{#/blank#}(sight) in the universe. For centuries, people {#blank#}2{#/blank#}(show) great interest in studying them. In 1682, Edmund Halley, an astronomer, noticed a comet that was especially bright and large. Based on his calculations, Halley predicted that this bright comet would return in 1758 or 1759—this was about 75 years {#blank#}3{#/blank#} he first saw the comet. The comet really returned on time and it was named "Halley's Comet" in honor of Edmund Halley.
