    One sheep, two sheep，632 sheep…still awake.

    People always believe that counting sheep {#blank#}1{#/blank#}(be) helpful to their sleep. But does it {#blank#}2{#/blank#}(real) work?

    Scientists at Oxford University tested it. Two sleep researchers looked at the people who had {#blank#}3{#/blank#}(difficult) in sleeping. They divided them {#blank#}4{#/blank#}different groups. Then they asked them to try all kinds of ways to help {#blank#}5{#/blank#}(they) fall asleep quickly.

    Surprisingly, it {#blank#}6{#/blank#}(take) those who were asked to count sheep more time to fall asleep than those who weren't. But when they were asked to imagine a relaxing picture-- a beach, for e {#blank#}7{#/blank#}, they fell asleep about twenty minutes{#blank#}8{#/blank#}(soon) than before, according to a report in The New York Times.

    “Sometimes, counting tasks are OK, b {#blank#}9{#/blank#}they are thought as stressful by many people,” Dr. Richards told ABC News.

    “As {#blank#}10{#/blank#}result, it may be a good way to try imagining colored fish slowly swimming in a river to help you sleep at night,” suggested Richards.
