Museums have changed. They are no longer places that one “should”go but to e{#blank#}1{#/blank#} . At a s{#blank#}2{#/blank#} museum in Canada, you can feel your hair stand on end as harmless electricity passes through your body. At the Children's Museum in New York,you can play an African drum. There are no “Do Not Touch” s{#blank#}3{#/blank#} in some other museums in the USA.

    More and more museum directors have realized that people learn beat when they can become part of what they are seeing. In many science museums, the visitors are encouraged to t{#blank#}4{#/blank#} , listen, operate and experiment so as to discover scientific rules for themselves.

    The p{#blank#}5{#/blank#} is not only to provide fun, but also help people feel at home in the world of science. If people don't understand science, they will be afraid of it; and if they are afraid of science, they will not make the best use of it. One cause of all these c{#blank#}6{#/blank#} is the increase in wealth and spare time. A{#blank#}7{#/blank#} cause is the growing number of young people. Many of them are college students or college graduates. They see things in a new and different  w{#blank#}8{#/blank#} . The old museums have been changing and the government is e{#blank#}9{#/blank#} the building of new, modern museums. In the States and Canada, there are more than 6 000 museums, almost twice as m{#blank#}10{#/blank#} as there were 25 years ago

    There was once a little boy with a bad temper(脾气). He got a{#blank#}1{#/blank#} easily and often shouted at those who loved him. One day, his father gave him a bag of nails(钉子) and told him, "Every t{#blank#}2{#/blank#}you lose your temper, drive a nail into the fence."

    The first day the boy drove 37 nails into the fence. Then the n{#blank#}3{#/blank#}got smaller. The boy found that it was e{#blank#}4{#/blank#}to hold his temper than to drive those nails into the fence.

    F{#blank#}5{#/blank#} the day came when the boy didn't lose his temper at all. He told his father about it and the father said, "Now, my son, pull o{#blank#}6{#/blank#} one nail each day when you are able to hold your temper."

     Days passed and the young boy was finally a{#blank#}7{#/blank#}to tell his father that all the nails were gone. The father took his s{#blank#}8{#/blank#} by the hand, led him to the fence and said, "You have done very well, my son, but look at the holes in the fence. The fence will never be the same as b{#blank#}9{#/blank#}. When you are in anger, what you do leaves a scar(伤疤) just like this. You can put a knife into a man and draw it out. No matter how many times you say sorry, the wound(伤口) is s{#blank#}10{#/blank#}there. A verbal(口头的) wound is as bad as a physical(身体上的) one".
