Рекомендации по переводу
Перевод английского предложения не следует начинать с первого слова. Любое предложение надо дочитать до конца и лишь после этого осмыслить его и оформить средствами русского языка.
Если понимание (перевод) предложения вызывает затруднение, рекомендуется прежде всего определить в нем сказуемое. Сказуемое составляет смысловой центр предложения, занимает относительно постоянное место и обычно имеет формальные признаки.
