      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.

you can see the city very well. It's very interesting.
