Помогите, пожалуйста перевести правильно: Meg, the eldest of the four, was sixteen, and very pretty, being plump and fair, with large eyes, plenty of soft, brown hair, a sweet mouth and white hands of which she was rather vain. Fifteen-year-old Jo was very tall, thin and brown, and reminded one of a colt; for she never seemed to know what to do with her long limbs, which were very much in her way. She had a decisive mouth, a comical nose and sharp, grey eyes, which appeared to see everything, and could be fierce, funny or thoughtful. Her long, thick hair was her one beauty; but it was usually bundled in a net, to be out of her way. Jo had round shoulders, big hands and feet, a fly-away look to her clothes and the uncomfortable appearance of a girl who was rapidly shooting up into a woman and didn't like it. Elizabeth - or Beth, as everyone called her - was a rosy, smooth-haired, bright-eyed girl of thirteen, with a shy manner, a timid voice and a peaceful expression, which was seldom disturbed. Her father called her 'Little Miss Tranquillity', and the name suited her excellently; for she seemed to live in a happy world of her own, only venturing out to meet the few whom she trusted and loved. Amy, though the youngest, was a most important person - in her own opinion at least. A regular snow-maiden, with blue eyes and yellow hair curling on her shoulders, pale and slender, and always carrying herself like a young lady mindful of her manners. What the characters of the four sisters were, we will leave to be found out.
