a rush the leaflets.

Boris woke up when it was 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 found 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.

Dear Helen,

How are the things going on? Did something new happen in your life? Having received your letter, I wanted to answer it immediately. But I was working a lot during the last two weeks. So I was pressed for time and did not manage to carry out my intentions.

In my country spring has already set. It is quite warm and really sunny all days long. Being at work I always imagine myself strolling down some parks. I wish you could join me! It would be funny! Some days ago my friend advised me to read a very interesting book. I did it and I would like you to know this author. Are you ready to read good litterature?

Tell me more about your work and free time. Are you satisfied with all this? What are your plans for this summer? Maybe we will be able to meet one day?
