Эми: Расскажи о своем вчерашнем дне, Джек.
Джек: Ну, в 9 часов начались занятия, и я учился весь день.
Эми: Нет, я хочу узнать о чем-нибудь интересном!
Джек: Я начал читать интересную книгу о Дракуле. И я закончил другую книгу о Диком Западе. Еще я смотрел интересую программу о НЛО по телевизору.
Эми: Звучит здорово!
Джек: Да, но в школе ничего интересного не произошло. Мы слушали учителей, шел дождь. Я шел домой по дождю, поэтому домой я пришёл очень мокрый. Затем я сидел дома и решил почитать комиксы.
