The best plan to cure yourself of a cold is to drink plenty of water or juice and not coffee, tea, and cola drinks to keep enough water in your body. think of what your body is telling you when you have a cold: sleep if you want to, have a warm bath to make aches and pains in the bones easier. and because you know how bad you can feel when you have a cold, protect the people around you by staying at home and coughing and sneezing into a handkerchief and washing your hands often with warm water and soap.   перевод   лучший способ вылечить себя от простуды - выпить много воды или сока, а не выпить кофе, чай и колу, чтобы поддерживать достаточное количество воды в организме. подумайте о том, что ваше тело говорит вам, когда вы простужаетесь: спать, если хотите, иметь теплую ванну, чтобы облегчить боль и боли в костях. и потому что вы знаете, как плохо вы себя чувствуете, когда простужаетесь, защищайте окружающих вас людей, оставаясь дома, кашляете и чихаете в носовой платок и часто моете руки теплой водой с мылом.

        Last summer I was writing a letter to my grandparents living a nearby village. Being aware of their desire to hear from us as often as possible it was a right decision of mine to write them a letter today, because I knew it would be delivered by  tomorrow morning by the time they will be drinking tea. 
        "Have you finished the letter yet ?", -my younger brother rushed into the room, his eyes worried and I could read a kind of envy on his face he experienced on my writing a letter. "O, you still have been writing it", - he settled down and went to me closer. "I do hope you mentioned me in your letter, especially you had to describe my success at math this month".
           "I had written about you before you ran into the room as if you had been chased by a couple of tigers",- I answered and returned to my letter. "I hope they will have got it by tomorrow",- he went to the window and looked out. "And don`t forget to mention that it has been raining cats and dogs all the day long".
          "I will write about the weather, though you know they have the similar weather conditions in the village, because they live close to our hometown", - I added a sentence and got up. Then I asked him, - if he wanted to join me on my  way to the post office, he agreed, and we left. The letter must be sent right now, he knew it so it took us only half an hour to get there and pay postage.
