Exactly when the first people arrived in what we now know as California，no one really knows. However，{#blank#}1{#/blank#}is likely that Native Americans were living in California at least fifteen thousand years ago.

    Scientists believe that these first settlers {#blank#}2{#/blank#} (cross) the Bering Strait in the Arctic to America {#blank#}3{#/blank#}means of a land bridge which existed in prehistoric times. In the 16th century，after the {#blank#}4{#/blank#} (arrive) of Europeans，the native people suffered greatly.

    Thousands were killed or forced into slavery. {#blank#}5{#/blank#} addition，many died from the diseases brought by Europeans. However，some survived these terrible times，and today there are more Native Americans {#blank#}6{#/blank#}(live) in California than in any other state.

    In the 18th century，California was ruled by Spain. Spanish soldiers first arrived in South America in the early 16th century，{#blank#}7{#/blank#} they fought against the native people and {#blank#}8{#/blank#}(take) their land.

    Two centuries later，the Spanish had settled in most parts of South America and along the northwest coast of what we now call the United States of {#blank#}9{#/blank#} first Spanish to go to California，the majority were religious men，{#blank#}10{#/blank#} ministry was to teach the Catholic religion to the natives.

    A best friend is someone {#blank#}1{#/blank#} you can tell everything to, even your most personal {#blank#}2{#/blank#} (feel) and thoughts. Anne Frank treated her diary {#blank#}3{#/blank#} her best friend. The German Nazis were in search of Anne and her family. The family had to hide away from the chase. They didn't dare to go out even in the evenings. They had to stay {#blank#}4{#/blank#}(indoor) day and night. Not {#blank#}5{#/blank#}(be) able to go out for such a long time, Anne missed the beauty of nature so much that she {#blank#}6{#/blank#}(grow) crazy about everything to do with {#blank#}7{#/blank#}. She stayed up until eleven thirty one evening on purpose just to see {#blank#}8{#/blank#} moonlight. She said, "This is the first time that I have seen the moonlight {#blank#}9{#/blank#} I came here."

    {#blank#}10{#/blank#}(fortune), the family were discovered at last and taken away from the hiding place.

    Should naps(小睡) actually{#blank#}1{#/blank#} (take) during the day? Well, we certainly know from{#blank#}2{#/blank#}(evident) in the sleep center and that of many other scientists that naps can give you benefits for both your brain{#blank#}3{#/blank#} your body. But naps can actually be{#blank#}4{#/blank#} double-edged sword because while we're awake during the day, we're building up sleepiness or sleep pressure. So when you try to fall asleep at night, you'll fall asleep quickly and then you'll stay asleep. And when we sleep, we actually release that sleepiness so that we wake up the next morning feeling{#blank#}5{#/blank#}(refresh).

    So if you take a nap during the day, especially if you take it too late in the afternoon, you will actually release some of that sleepiness and it will make it much{#blank#}6{#/blank#}(hard) to fall asleep and stay asleep soundly throughout the night. So the advice would be if you don't struggle with your sleep and you can nap{#blank#}7{#/blank#}(regular), then naps are just fine.

    But if you do find it difficult{#blank#}8{#/blank#} (fall)asleep or stay asleep at night, then you should avoid naps and try to build up that healthy sleepiness in the evening.

    The ideal nap depends on{#blank#}9{#/blank#} you want from that nap. Different stages of sleep actually give you different types of brain and body{#blank#}10{#/blank#} (benefit).

The day is known as the Moon Festival, as at that time of the year the moon is at its roundest and {#blank#}3{#/blank#}(bright). It is an evening celebration in {#blank#}4{#/blank#} families gather together and eat moon cakes.
