ответ: I don’t know what to tell him. They saw Maria near the cinema three days ago. Lucy loved him very much. They didn’t want to listen to her. Last Monday this man helped us with luggage when we arrived at the hotel.Where did you see them? This book is exciting. I really enjoyed it. When I entered the room I saw her near the window. She looked at me and smiled. Open the window, please. – Wait a minute. I’ll write two lines more and then open it.You should see her diploma of educaion.
At the present I go to school, so I'm very busy on weekdays. Because of this, unfortunately, I can't help in the house as often as my parents wish. However, I do my best to find the time to clean house.Every morning I get up and without any loss of time, I do my bed and go to the bathroom. Yawning, I wash my face, then I brush my teeth and go to have breakfast. After breakfast, I always wash the dishes myself after me and my family, because my mom and dad leave for work before me. They have no time to wash the dishes.At 8 o'clock sharp, I make my way to the school and at 4 on the dot I come back home. On my return, I cook something easy so that I might eat, and then I get down to the lessons. Lessons take me from half an hour to two hours a day. It all depends on how much homework our teacher gives to us. Then I put all the books and notebooks into place and start cleaning my room. Every day I dust. Every other day I vacuum. Sometimes in the evening we go shopping together with dad.From time to time, I help my mom wash, iron and do spring cleaning. But this happens not quite often. On the weekend I rest, meet friends, play in the yard and in the park across the street. She often gets angry with me for this, so I try to study well and make her happy making good progress in studies.
