You might have seen this in US TV dramas. A group of girls knock on people's doors, trying to sell cookies. What are they doing? They are Amercican Scouts（女童子军）,and {#blank#}1{#/blank#} (sell) cookies is a tradition of {#blank#}2{#/blank#} (they).

    Selling cookies is just one activity among all the fun things that Girl Scouts do. The Girl Scouts of the USA is a group {#blank#}3{#/blank#} (found) in 1912.It offers all kinds of activities to girls and lets them learn skills.

    Boys can be scouts too. {#blank#}4{#/blank#} they join a different group called the Boy Scouts of America (RSA), {#blank#}5{#/blank#} was founded in 1910.

    Now there are 1.9 million Girl Scouts in the US, according to the group, Usually, they go {#blank#}6{#/blank#} (camp) and learn how to build fires and use a compass. Sometimes they also stay {#blank#}7{#/blank#} (indoor) doing crafts or learning arts. Every time they do an activity or pass a test, they get a badge.

    The Boy Scouts love to win the badges too. They have a ranking system. And winning enough badges is {#blank#}8{#/blank#} must to get into a {#blank#}9{#/blank#} (high) rank. The highest rank is "Eagle", which {#blank#}10{#/blank#} (require) at least 21 badges. Neil Armstrong the first man on the moon, and Bill Gates, the father of Microft, were both Eagle Scouts when they were young.

    I wonder if it is because I haven't been able to be outdoors for so long {#blank#}1{#/blank#}I have grown so crazy about everything to do with nature. I can well remember that there was a time{#blank#}2{#/blank#}a deep blue sky, the song of the birds, moonlight and flowers could never have {#blank#}3{#/blank#}(keep) me spellbound. That has changed since I came here. For example, one evening when it was so warm, I stayed {#blank#}4{#/blank#} (wake) on purpose until half past eleven in order to have a good look at the moon by myself. But as the moon gave far too much light, I didn't dare open{#blank#}5{#/blank#}window. Another time five {#blank#}6{#/blank#}(month) ago, I happened {#blank#}7{#/blank#}be upstairs until the window had to {#blank#}8{#/blank#} (shut). The dark, rainy evening, the wind, the thundering clouds held me {#blank#}9{#/blank#}(entire) in its power; it was the first time in a year and a half that I{#blank#}10{#/blank#}(see) the night face to face...

    Exercise could not only benefit your body, but also improve your memory, researchers found{#blank#}1{#/blank#}(recent).

    In their paper, researchers in the United States and Japan{#blank#}2{#/blank#}(introduce) their experiment and conclusion.

    Scientists invited 36 volunteers{#blank#}3{#/blank#}were in their early 20s to do 10 minutes of light exercise before taking a memory test in which they{#blank#}4{#/blank#}(show) pictures like broccoli(西兰花) or picnic baskets and asked to recall them later. The same experiment was repeated with the same group of volunteers without exercising. “The memory task really was quite{#blank#}5{#/blank#}(challenge),” said Michael Yassa, co-author of the study. “ We used very similar items to see if they would remember {#blank#}6{#/blank#}it was this exact picnic basket versus that picnic basket.”

    Researchers also scanned brains of some of the participants during the experiment.

    They found increased communication between parts{#blank#}7{#/blank#}(involve) in the storage and recollection of memories in brains of those who had exercised.

This suggested that just 10 minutes of light exercise might have a positive effect {#blank#}8{#/blank#}memory power.

    As all{#blank#}9{#/blank#}volunteers in the experiment were relatively young, researchers are still working{#blank#}10{#/blank#}(look) at the influence of light exercise on older people. “Our main goal is to try to develop an exercise way that can be used by older adults who might have disabilities,” said Yassa.

    Marty Fielding began to suffer from a muscle disease when he was 10, {#blank#}1{#/blank#} sometimes made him clumsy and drop things or bump into furniture. The doctors don't know {#blank#}2{#/blank#}(exact) what is wrong with him, so they don't know how to make him better. But he has to learn to adapt    {#blank#}3{#/blank#} his disability. When some people cannot accept him for who he is, he doesn't get{#blank#}4{#/blank#}(annoy). He just ignores them.

    All in all, he has a good life. His ambition is to work in a computer software firm when he {#blank#}5{#/blank#} (grow) up. He has a very busy life and doesn't have time to sit around {#blank#}6{#/blank#}(feel) sorry for himself. In many ways his disability has helped him grow stronger psychologically and become {#blank#}7{#/blank#}(independent). He has to work hard to live{#blank#}8{#/blank#}normal life. From him, we know we shouldn't feel sorry for the disabled or make fun of{#blank#}9{#/blank#}and that we shouldn't ignore them either. Just accept them for who they are and give them {#blank#}10{#/blank#}(encourage) to live as rich and full a life as you do.

Body language is one of {#blank#}1{#/blank#} most powerful means of communication, often even more powerful than {#blank#}2{#/blank#}(speak) language. People around the world show all kinds of feelings, wishes and attitudes that they might never speak aloud. {#blank#}3{#/blank#} is possible to "read" others around us, even {#blank#}4{#/blank#}they do not want us {#blank#}5{#/blank#}(catch) their unspoken communication. Of course, body language can be misread, but many{#blank#}6{#/blank#}(gesture) and actions are universal. The most universal {#blank#}7{#/blank#}(face) expression is, of course, the smile—its function is to show happiness and put people {#blank#}8{#/blank#} ease. It does not always mean that we are {#blank#}9{#/blank#}(true) happy, however. Smiles around the world can be false, hiding other feelings like anger, fear or worry. There {#blank#}10{#/blank#}(be) unhappy smiles, such as when someone "loses face" and smiles to hide it. However, the general purpose of smiling is to show good feelings.
