Have you heard of Lake Titicaca? It is the largest lake in South America in terms of water volume and surface area,     1    (locate) on the border between Bolivia and Peru.

The life of the ancient people who once lived around the lake and whose culture was thought to be highly     2    (advance), has long remained a secret. Recently,     3    , scientists taking part in an exploration project at the lake have found     4    they consider to be a 1000-year-old temple beneath the water.     5    (dive) from the study group have discovered a building,     6    scientists think is the remains of a temple built by the people who once lived beside the lake. The project leaders hope to begin raising important materials from the site later this week, weather     7     (permit).

“The scientists have not yet had the opportunity     8    (study) the materials carefully,” said project director, John Aubi. “But some have put forward the idea that the remains date from this period because of their similarities     9    those found elsewhere.”

The research team has so far this year made more than 200 dives into water 30 meters deep. During these dives, they have been recording     10    ancient remains on film. There will be a meeting, starting later this year to review the film.

Chinese archaeologists announced the discovery of over 500 cultural relics, during an ongoing excavation at the Sanxingdui Ruins site in Guanghan, Southwest China's Sichuan province. The relics were    1    (dig) out in six sacrificial pits (坑) that date back over 3,200 years.
