    Sleep is something we all do. But some people need to sleep more than others. Babies sleep most of the time. Children in school sleep about ten to twelve hours a night. Most adults sleep only seven or eight hours. {#blank#}1{#/blank#}

    All parts of our bodies have to rest after they work.. Our arms need a rest after we lift heavy thing, When we run fast, our legs work hard. They get tired. We have to rest them. Our brains work hard, too. {#blank#}2{#/blank#}. We can sit quite still and rest our arms and legs. But our brains aren't resting. They go right on thinking as long as we are awake.

    Our brains slow down a bit when we sleep and dream. {#blank#}3{#/blank#} Instead of thinking wide-awake thoughts, our brains make up dreams. Some dreams are very pleasing. Some are not. Most of the time we forget them when we wake up.

    Scientists have tried to find out what would happen if people were not allowed to sleep. They asked some people not to go to bed. The people stayed up all night and all the next day. They stayed up the next night too, and the day after. They played games, but they made mistakes. They forgot things. {#blank#}4{#/blank#}

    The people grew rude and mean. They became angry with their friends. Finally they were too tired to stand up. When they sat down, they fell asleep.

    Scientists have found that if people are not allowed to sleep and to dream, they act in an unusual way. {#blank#}5{#/blank#} But we do know that we need it to stay well. So tonight have a good sleep. Lie down under the covers. Shut your eyes. Let your thoughts wander. Soon you'll stop thinking. You'll be asleep.

A. It was hard for their tired brains to work.

B. When we are awake, they help us pay attention to the world around us.

C. But babies, children, and adults — all of us need to have our sleep.

D. Good sleep helps to improve one's memory.

E. No one knows why sleep is so good for us.

F. But even as we sleep our brains are doing some work.

G. Of course you will have a good sleep.

    Happiness is for everyone. You don't need to care about those people who have beautiful houses with large gardens and swimming pools or{#blank#}1{#/blank#} and so on. Why? Because those who have big houses may often feel lonely and those who have cars may want to walk on the country roads at their free time.

    In fact, happiness is always around you if you put your heart into it. {#blank#}2{#/blank#} When you study hard at your lessons, your parents are always taking good care of your life and your health. When you get success, your friends will say congratulations to you. When you do something wrong, people around you will help you to correct it. {#blank#}3{#/blank#} All these are your happiness. If you notice a bit of them, you can see that happiness is always around you.

    Happiness is not the same as money. It is a feeling of your heart. When you are poor, you can also say you are very happy, because you have something else that can't be bought with money. {#blank#}4{#/blank#}, because you have more chances to challenge yourself. So you cannot always say you are poor and you have bad luck. As the saying goes, life is like a revolving(旋转的)door. When it closes, it also opens. {#blank#}5{#/blank#}

B. If you take every chance you get, you can be a happy and lucky person

    Find a quiet location. Keep a routine. Focus on one subject at a time. It all seems like sound advice for students who need to hit the books, {#blank#}1{#/blank#} . Here's a list of tips from Carey, a scientist, for getting the most out of your study time.

    {#blank#}2{#/blank#}.

    Doing practice quizzes can help you retrieve（检索）information on test day. “Tests have a very bad reputation as a measurement tool,” Carey says. But psychologists have found self-tests slow down the forgetting of material you've studied. “If you study something once, and then you test yourself on it,” Carey says, “you do better than if you study it twice over.”

    Move around

    {#blank#}3{#/blank#} . “If you move around and study the same material in several places,” he says, “you may be forming multiple associations for the same material. So it's better anchored in your brain, and you can pull it out easier.”

    Mix it up

    Think about a football who does strength training, speed training and drills. Carey says alternating between different facets facts of a subject in a single sitting can “leave a deeper impression on the brain”. For example, when studying French, do some verbs, some speaking and some reading. {#blank#}4{#/blank#} .

    Space it out

    Information learned in a hurry is lost just as fast. So if you really want to learn, space out shorter, hour-long study sessions. “There's no doubt that you can cram for（突击备考）an exam.” Carey says, “{#blank#}5{#/blank#} . And once it's gone, “it's gone. You're not getting it back.”

A. Test yourself

B. Study it and practice more

C. and it turns out that some of them are in great help

D. but recent studies indicate the conventional wisdom is wrong

E. The problem is that it's so easy to forget what you just crammed

F. Changing up where you study can help you keep more information

G. Spending your time in deep concentration on just verbs isn't effective

    ● {#blank#}4{#/blank#}. Go over your notes as soon as you can after class. Review important points mentioned in class as well as points that confuse you.
