In AD79, the ancient Roman city of Pompeii, in southern Italy, 1． (destroy) by a volcanic eruption that buried many of its buildings. Archaeologists (考古学家) 2． (observe) it for almost 300 years but now they have a new tool for 3． (understand) how Pompeii might once have looked—virtual reality (VR).

Researchers Danilo Campanaro and Giacomo Landeschi, from Lund University in Sweden, used data that were collected by drones (无人机) to create a 3D computer reconstruction of one of its most amazing buildings. They then fed the reconstruction into a video game system 4． a VR model is made. The idea is not just to recreate the buildings 5． to understand a bit more about how Roman people might have experienced them. Campanaro and Landeschi asked 6． (volunteer) to take a virtual tour of the house in both summer and winter light. The researchers used special eye-tracking technology to record 7． (exact) which areas people looked at and for how long. From this, the team concluded that the building used clever design 8． (draw) attention to the very objects 9． showed off the wealth and status of its owner—perhaps a man called Lucius Valenius Flaccus, 10． ring was found in the ruins.
