Boris woke up when it is already quite light. He looked at his watch. It was a quarter to seven. Quick! Boris jumped out of bed and ran to the bathroom. He had just time to take a cold shower and drank a glass of tea with bread and butter. He was in a hurry to catch the eight o'clock train. At the railway station he met three other boys from his group. They all had small backpacks and fishing rods. In less than an hour they got off the train at a small station near a wood. They walked very quickly and soon finded themselves on the shore of a large lake. The boys spent the whole day there fishing, boating and swimming. They returned home late at night, tired but happy.
