Помогите грамотно перевести текст!Срочно надо....Заранее спасибо)
Joan Edison came to their half of the fifth grade from Maryland in March. She had a thin face with something of a grown-up’s tired expression and long black eyelashes like a doll’s. Everybody hated her. That month Miss Fritz was reading to them during homeroom about a girl, Emmy, who was badly spoiled and always telling her parents lies about her twin sister, Annie; nobody could believe, it was too amazing, how exactly when they were despising Emmy most, Joan should come into the school with her show-off clothes and her hair left hanging down the back of her fuzzy sweater instead of being cut or braided and her having the crust to actually argue with teachers. “Well I'm sorry,” she told Miss Fritz, not even rising from her seat, “but I don't see what the point is of homework. In Baltimore we never had any, and the little kids there knew what’s in these books.”
Charlie, who in a way enjoyed homework, was ready to join in the angry moan of the others. Little hurt lines had leapt up between Miss Fritz`s eyebrows and he felt sorry for her, remembering how when that September John Eberly had half on-purpose spilled purple Sho-Card paint on the newly sandpapered floor, she had hidden her face in her arms on the desk and cried. She was afraid of the school board. “You're not in Baltimore now, Joan,” Miss Fritz said. “You are in Olinger, Pennsylvania.”
The children, Charlie among them, laughed, and Joan, blushing a soft brown color and raising her voice excitedly against the current of hatred, got in deeper by trying to explain. “Like there, instead of just reading about plants in a book, we’d one day all bring in a flower we'd picked and cut it open and look at in a microscope.” Because of her saying this, shadows, of broad leaves and wild slashed foreign flowers, darkened and complicated the idea they had of her.
Miss Fritz puckered her orange lips into fine wrinkles, then smiled. “In the upper levels you will be allowed to do that in this school. All things come in time, Joan, to patient little girls.” When Joan started to argue this, Miss Fritz lifted one finger and said with the extra weight adults always have, held back in reserve, “No. No more, young lady, or you’ll be in serious trouble with me.” It gave the class courage to see that Miss Fritz didn’t like her either.-

СРОЧНО!!!!! Стеклянный флакон с йодом, закрытый завинчивающейся пластмассовой крышкой, стоит на подоконнике. Окно плотно закрыто. Спустя некоторое время
подоконник оказался испачканным йодом. Что случилось и почему так произошло? Флакон всё это время никто не трогал.
