A few days ago I was very ill.I had a terrible headache, I had a very  high temperature and I cneezed every minutes. It was so awful to have a runny nose! The doctor said that I should stay in bed but I didn't want. It was so boring to stay in bed when the weatther was so good and warm. I hate TV but I watched everything. My mother took me a lot of medicines. Then I felt better!  
 Несколько дней назад я очень болел. У меня были ужасные головные боли, очень высокая температура, и я чихал каждую минуту. Это так ужасно иметь насморк. Доктор сказал, что я должен лежать в постели, но я не хотел. Это так скучно оставаться в постели, когда на улице такая хорошая и теплая погода. Я ненавижу телевизор, но смотрел все подряд. Мама давала мне много лекарств. И мне стало лучше!
