Полный текст:
Some scientists study space. They look for patterns made by the stars. Sometimes, rocks fall from other planets and fly through space. These rocks are called asteroids. A big one fell on planet Earth 65 million years ago. Some people think this is why the dinosaurs disappeared. Scientists have found dinosaur skeletons, but haven’t found any dinosaur skin.
Упр. 4 — ответы по тексту Class Book:
- Some ate meat and some ate plants.
- About 65 million years ago.
- About 12 metres long.
- There were many different types — more than 700.
- Because scientists have found dinosaur bones and skeletons, but not dinosaur skin, so they don’t know the colour.
В №4 точные цифры из №3–4 лучше сверить с текстом Class Book — на фото его страницы нет.
Как понять принцип
- В алфавитном порядке сравниваем сначала первую букву: asteroid → disappear → Earth → fall. Если первые буквы одинаковые, смотрим вторую: scientist и skin; во втором слове вторая буква \(k\), поэтому scientist идёт раньше.
- Слово fall / fell в банке дано как одна позиция, поэтому в списке это одна строка.
- В упр. 3 важно менять форму слова:
- scientists — множественное число;
- patterns, rocks, asteroids — тоже множественное;
- fell — прошедшее время от fall;
- disappeared — прошедшее время;
- skin — неисчисляемое, без окончания \(-s\).
- Проверка: «A big one fell on planet Earth» — речь об одном астероиде, поэтому fell, а не fall.
