城市与交通2

Be careful and don't lose your important ticket

The traffic in the city center is always very busy

You must be very careful when you want to cross the wide road

Always stop, look, and listen before you walk

Many people in the city drive a private car to go to work

My uncle is a taxi driver, and he works very hard.

He knows every place and every street in this city

He can take you east, west, south, or north.

A police officer often stands at the crossing to help people.
