Короче, всё просто, когда говорящий задает вопрос о неизвестных ему лицах или объектах, он заменяет эти слова местоимениями who, whom, whose, what и which.
Вопросительные местоимения в английском языке применяются только в вопросах специального типа. Они ставятся в начале предложения перед глаголом.
Эти местоимения принадлежат к классу вопросительных слов, известных также, как wh-words, так как почти все они начинаются с букв wh.

My favourite holidays are the winter holidays. No matter how freezy and frosty it is outside, I am always in a good mood, because New Year is coming and there will be a lot of presents, congratulations and laugh. At home my parents and I always decorate the Christmas tree, it is real pleasute to do it together. On winter holidays you can make a snowman with your friends, go skiing and skating. Winter is very nice season of the year, and I don't understand people hating it.
Soon we will cook a lot of tasty dishes,we will invite guests to the New Year party, and make wishes at 12 o'clock. I am looking forward to selebrating this holiday. I hope all your dreams will come true in such special time of the year.
