One day I saw an interested program on TV. It 21
was about the problem of traffic in our cities. It seem 22
that a great deal of damages is done by traffic. All 23
our cities are suffered from this. Some buildings are actually 24
falling to pieces. It"s often fast to walk than to go by car or 25
bus. The problem has been getting worse for long time. This is 26
only one problem among thousands of others in our cities. All sorts 27
of terrible things were happening to our cities. The biggest 28
problem is, "What can we do about it" Our roads were ever 29
designed for such a big traffic. It takes more and more time 30
to get from one place to another.
