The bicycle is one of the simplest but most useful inventions in the world. What is the most surprising is that it was not {#blank#}1{#/blank#} earlier, although the great inventor Leonardo da Vinci had {#blank#}2{#/blank#} pictures for bicycles and flying machines and some other things. Those things were not produced {#blank#}3{#/blank#} long after he died.

A person riding a bicycle uses very little {#blank#}4{#/blank#} to make the bicycle move, and there is no pollution at all when you are riding. Even so, in most developed {#blank#}5{#/blank#} , most people don't go to work by bicycle. It is not {#blank#}6{#/blank#} the bicycles are expensive or people feel {#blank#}7{#/blank#} if they ride to work. It's because the number of cars on the roads becomes larger. It certainly becomes more {#blank#}8{#/blank#} to ride a bicycle. As a result, more people put their bicycles away and go to work {#blank#}9{#/blank#} their cars. And in this way, the situation is made more serious. Perhaps the best way to make riding safer and more popular is to {#blank#}10{#/blank#} paths only for bicycles.

    Look! You can see a ball under the desk. That's Kate's desk. The ball is{#blank#}7{#/blank#}, too. This is my desk. You can see a {#blank#}8{#/blank#}on it.

    When young people in the United States get together for fun, probably they will dance. The ways that boys and girls dance will often change every year. They{#blank#}1{#/blank#}learning the newest dances.

    Years ago, the dances of young people were not very different from those of their parents, but high school and college students of today have{#blank#}2{#/blank#}their own music and dances. They like the new music that people can dance to in different ways.

    In the USA, there are many dances that are loved by young people, but the history of the dances isn't{#blank#}3{#/blank#}, the Twist(摇摆舞), for example. In the late 1950s, Chubby Checker started a dance that he called the "Twist" to make himself slim.

The word "chubby" means "very fat". That was why the singer and dancer called him Chubby.
