Have you ever {#blank#}1{#/blank#} (stay) up late? If so, you know that not getting enough sleep can make you tired. Not sleeping enough can also make {#blank#}2{#/blank#} hard to think clearly the next day.

    Sleep scientists have long known that getting a good night's sleep is of great {#blank#}3{#/blank#} (important). It helps kids to be able {#blank#}4{#/blank#} (do)their best during the day.

    A recent study shows that sleep {#blank#}5{#/blank#} (help) improve problem-solving skills and {#blank#}6{#/blank#}(create) thinking. For the study, two groups of students answered {#blank#}7{#/blank#} math problems. The group that slept for eight hou rs solved the problem {#blank#}8{#/blank#} (correct) more often than the group that did not get enough sleeping.

    While you sleep {#blank#}9{#/blank#} night, your brain is busy doing its “homework”. It sorts out (整理) the information {#blank#}10{#/blank#} you get in the day. Getting enough sleep each night can improve your thinking ability. That will surely help you do your best at school. Experts say that, in return, can lead to better grades.

    It is often said that eyes can speak. In a bus you may look at a stranger,{#blank#}1{#/blank#} not too long. If he notices that he is being stared at, he may feel {#blank#}2{#/blank#} (comfort). It is the same in daily life. When you are {#blank#}3{#/blank#} (look) at for several more times, you will look at yourself up and down to see if there is anything wrong {#blank#}4{#/blank#} you. If nothing goes wrong, you {#blank#}5{#/blank#} (feel) angry with the person who is looking at you. Eyes can speak, right?

    {#blank#}6{#/blank#} (look) too long at someone may seem to be impolite. But sometimes things are different when it {#blank#}7{#/blank#} (come) to staring at the opposite sex, if a man glances at a woman for more than ten seconds, his intentions are obvious, that is, he wishes to attract {#blank#}8{#/blank#} (she ) attention, to make her understand that he is admiring her.

    In fact, continuous eye contact is limited to {#blank#}9{#/blank#} (love) only, who will enjoy looking at each other {#blank#}10{#/blank#} (gentle ) for a long time，to show affection that words cannot express. Evidently, eye communication should be done according to the relationship between the two people.

    New York, 10 November 5:27 pm, yesterday. Biggest power failure in the city's history.

    Thousands of people got{#blank#}1{#/blank#}(stick) in lifts. Martin Saltzman spent three hours between the 21st and 22nd floors of {#blank#}2{#/blank#}Empire State Building. "There were twelve of us. But no one{#blank#}3{#/blank#}(panic). We passed the time telling stories and{#blank#}4{#/blank#}(play) word games. One man wanted to smoke but we didn't let him. Firemen finally got us out."

    "It was the best night we've ever had," said Angela Carraro,{#blank#}5{#/blank#}runs an Italian restaurant on 42nd Street. "We had lots of candles on the tables and the waiters were carrying candles on{#blank#}6{#/blank#}(they) trays. The place was full and all night, in fact, for after we had closed, we let the people stay on and spend the night here. Business was{#blank#}7{#/blank#}(good) than usual."

    The zoos had their problems like everyone else. Keepers worked through the night. They used blankets{#blank#}8{#/blank#}(keep) flying squirrels and small monkeys warm. While zoos had problems keeping warm, supermarkets had problems keeping cool. "All of our ice cream and{#blank#}9{#/blank#}(freeze) foods melted," said the manger of a store in downtown Manhattan. "They were worth $50,000."

    The big electric clock in the lobby of the Waldorf-Astoria Hotel in downtown Manhattan started ticking (滴答) again at 5:25 this morning. It was almost {#blank#}10{#/blank#}time.

    Eating soil can produce more effective results{#blank#}1{#/blank#}(compare) to eating slimming pills, claimed researchers from an Australian university. China Press{#blank#}2{#/blank#}(report)that researchers from the University of South Australia were looking for a way to improve the body's absorption towards medication to prevent mental illness.

    They{#blank#}3{#/blank#}(accident)found out that soil does not only attract fat, it could also stop fat from being absorbed into the body and round{#blank#}4{#/blank#}digestive system. Meanwhile, other researchers carried out an experiment by{#blank#}5{#/blank#}(separate)mice into two groups--one group{#blank#}6{#/blank#}(give) slimming pills and the other group with soil.

    After two weeks, the weight of the mice{#blank#}7{#/blank#}ate soil decreased obviously. This was the basis for claims that eating soil might make it{#blank#}8{#/blank#}(easy) for the body to excrete(排泄) fat than taking slimming pills.

    However, they {#blank#}9{#/blank#}(test)to see if eating soil is safe for the body{#blank#}10{#/blank#}if it could cause any side effects in the past few months.
