The disappearance of dinosaurs
Among the many unsolved mysteries about dinosaurs, what really interests me is their disappearance. One possible explanation is that there was a huge meteorite hitting Earth. But what I believed most was ash and gas from erupting volcanoes. Where so much magma went, all the living things including dinosaurs lost their lives. Besides, it is a fact that clouds of fire and smoke blocked the whole sky so that they had no sunshine to enjoy and no oxygen to take in.
Part 2 Focus on vocabulary (一）
