Reading: Central park (5 points)
I would like to tell about Central park. This big and beautiful park is located in the center of the
city. There are always a lot of people in this popular place. There are lovely sunlit lawns and quiet
spots hidden in the shade of trees. Right in the middle of the park there is a big lake with crystal
clear water. Swans, ducks and other water birds live there.
There are benches along the park’s paths. There are also a few cafes and other eateries where
visitors can relax enjoying a cup of coffee. Little guests will love to spend time at a small
playground. Bicycle lanes run around the park.
In summer this park becomes a very lively place. Some people come to picnic here. Others just
sit on soft grass while reading an interesting book or resting. During hot days people come here to
lie in the sun. For those who prefer active sports, there is a sports ground to play volleyball and
other sport games.
In winter this park becomes especially fascinating. It is always nice to walk along quiet paths and
listen to birds’ singing. Dog owners also come here to walk their pets.
