【简答题】
I often wondered why the people of Pompeii did not run away before the volcano erupted. As it turns out, they didn’t know what a volcano was. In fact, the Romans did not even have a word for “volcano”. 小题1: They had no idea that a volcano would destroy them. Starting from 20 August AD 79, there were some earthquakes near the volcano. 小题2: 然而,没有一个人很注意这些. Then, on 24 August, the mountain explored, pouring out a cloud of ash. It was also moving quite fast. Most of the human remains from Pompeii have been found on the roads away from the city. 小题3: The people were fleeing the city for their lives. However, they could not get away fast enough, 小题4: so they were buried beneath the ash. A famous Roman scholar happened to be on a boat nearby when all of this happened, so he went to the area to see what was going on. Even he didn’t know what a volcano was. 小题5: 不幸的是他也死于这场灾难中.
