Every individual is a member of a group called the community, and it is the duty of every citizen {#blank#}1{#/blank#} ask what he can do for his community. A good citizen {#blank#}2{#/blank#}(相信) that he should serve the community and not the community serve h{#blank#}3{#/blank#}. As students, there are many ways in {#blank#}4{#/blank#} you can serve the community. Above all, however, you have to acquire a certain amount of skill and experience b{#blank#}5{#/blank#} you can be of service to others. Your school has lots of{#blank#}6{#/blank#}(活动) which prepare you {#blank#}7{#/blank#} good citizenship. Many school societies train students to become good citizens who later p{#blank#}8{#/blank#} in volunteer work and serve the public in t{#blank#}9{#/blank#} of need. If you serve your community, you will grow {#blank#}10{#/blank#} to be a good citizen with a strong sense of responsibility.

    Many of us wake up {#blank#}1{#/blank#} (feel) tired in the morning. Many of us ignore the problem as the day goes on, forgetting that it might have a dangerous effect. Society even glorifies “burning the candle at both ends” as a sign of our {#blank#}2{#/blank#}(devote) to work and family.

    Believe {#blank#}3{#/blank#} or not, all this bad sleep has far-reaching consequences. We do not give ourselves enough chances to sleep. A survey of over 74,000 people found that 35% reported sleeping less than seven hours daily {#blank#}4{#/blank#} average. Furthermore, the quantity of sleep we allow ourselves {#blank#}5{#/blank#} (change) greatly over the past 15 years.

    This lack of sleep can lead to many serious {#blank#}6{#/blank#} (problem). One study found that {#blank#}7{#/blank#} (simple) limiting yourself to six hours of sleep a night for two weeks made performance on a timed attention task as poor as if you {#blank#}8{#/blank#} (stay) up all the night before.

    If you intend to try extending your sleep period, consider giving yourself a chance {#blank#}9{#/blank#}(sleep) longer for a full week. Your body clock might be programmed in a way {#blank#}10{#/blank#} keeps you from falling asleep quickly, but it might let you sleep longer.

    Daisy is a girl who cares about our environment. She always longs to help {#blank#}1{#/blank#}(endanger) species of wildlife. One day, she {#blank#}2{#/blank#}(wake) up and found a flying carpet which took her to many{#blank#}3{#/blank#}(place) to experience something amazing. In Tibet, Daisy saw an antelope looking sad and it told her the species was being killed. Then the carpet showed her a place {#blank#}4{#/blank#}there was some wildlife protection. There she came across {#blank#}5{#/blank#}elephant, from whom she knew they used to be hunted {#blank#}6{#/blank#}mercy. But now good things are being done to save local wildlife. Knowing that, Daisy burst into {#blank#}7{#/blank#}(laugh) in relief. At the end of the journey, she met a monkey {#blank#}8{#/blank#}(rub) itself to protect himself from mosquitoes. The monkey asked her to pay {#blank#}9{#/blank#}(much) attention to the rainforest. Finally, Daisy {#blank#}10{#/blank#}(full) understood the meaning of no rainforest, no animals, no drugs.
