Before you    1    a street, you must look to the right first and then to the left.
      In the morning and in the    2    when people go to or come back from work, the streets are very     3   .
Traffic is the most dangerous then.
     When you go by bus in England, you have to be careful, too. Always remember the traffic    4    on the
left. So you must be careful. Have a look first, or you may go the wrong way.
      In many English cities, there are big buses with two floors. You can sit on the    5    floor. From there
you can see the city very well. It's very interesting.
