A lot of people went to a hill for their holidays. The hill was called West Hill. It was a famous place of a
town. This time the town invited some good singers to sing in the park, so the people could have something to
do in the evenings. They planned to sing every evening for a week.
But on the first evening it rained. The singers were under cover (在遮蔽处), but the people had to sit in the
open (露天). The singers sang very well, but there was only one person (人) listening. The man was sitting in
a chair, under an umbrella.
After some time, one of the singers came over to the man and said, "I'm sure you like music, don't you ?
It's so kind of you to sit here and listen to us."
" No," said the man. "I don't like music at all. Please finish it quickly, and then I am going to close the gate.
And you see, it's time to go home."

Now the roads are crowded with cars, trucks and buses. They are not safe (安全的) for people.
Every day people are killed while they are crossing the road. Most of these people are old people and
children. Old people are often killed because they usually cannot see or hear very well. Children are killed
because they are not very careful. They don't look and listen before they cross the road.
A car, truck or bus cannot stop very quickly. If they are going very fast,they will travel many metres (光)
before they stop. People do not always understand this. They think a car can stop within (在……之内) a few
metres. It is very hard for people to know how fast a car is travelling. He may think it is going slowly when it is
going very quickly.

is safe to cross. The right way to cross the road is to walk quickly. It is not safe to run. If people run across the
