The bicycle is one of the simplest and most
useful inventions in the world. What is most surprising is that it was not {#blank#}1{#/blank#} (发明) earlier,
although the great inventor Leonardo da Vinci had drawn pictures of bicycles
and also of flying machines and some other things. Those things were not
produced until long after he {#blank#}2{#/blank#} (死).
A person riding a bicycle uses a little
energy to make the bicycle {#blank#}3{#/blank#} (移动), and
there is no {#blank#}4{#/blank#} (污染) at all when you
are riding. Even so, in {#blank#}5{#/blank#} (发达的) countries, most
people don' t travel to work by bicycle. It is not because the bicycles are
expensive or people feel {#blank#}6{#/blank#} (疲劳的) if they ride to
work. It's because the number of cars on the roads becomes {#blank#}7{#/blank#} (更大的). It certainly becomes
more {#blank#}8{#/blank#} (危险的) to ride a
bicycle.
As a result, more people put their bikes
away and go to work in 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#}9{#/blank#} (创造) paths
only for bicycles, and to make it so difficult and expensive for {#blank#}10{#/blank#}(驾驶员) to take
their cars into the city that they will go back to using their bicycles.
