Здравствуйте, помогите перевести
Alexander's Working Day
My working day usually starts like this. At exactly 6:00 my radio alarm buzzes. Though I am not a lazybones, in winter it is always difficult for me to wake up early. I do my morning exercises every morning. I know that good health is better than wealth. After having a shower I get dressed and brush my hair. It takes me about 40 minutes. I am in the habit of having only a light breakfast. After breakfast I grab my school bag and rush for college. Unfortunately I live far from the college. It takes me about one hour to get there.
Sometimes my mood depends on what classes I have. On some days lessons flash by very quickly, especially if they are on the humanities or Maths, which I like most, but they drag more slowly if they are on Chemistry or Biology and especially when we have to write tests on them. Our classes start at 8:20. Usually we have seven lessons a day. Each lesson lasts 45 minutes, but the breaks are too short: only 5 or 10 minutes. Fortunately we have a large break in the middle of the day which lasts 45 minutes. During this break we go to the canteen. At 3 o'clock, when the classes are over, I sometimes stay at college to play football with my groupmates.
In the evenings I am busy doing my homework. If I have some free time left, I go for a walk with my friends, read or watch TV. At about 8 o'clock all our family have supper. At 11:30 I take a shower and go to bed.
