In 1929, a peasant in Sichuan Province uncovered jade (玉器) and stone artifacts(手工艺品) while repairing a ditch(沟渠) located about 24 miles from Chengdu. But their significance wasn’t understood until 1986, when archaeologists unearthed two pits(大坑) of Bronze Age treasures. The discovery suggests an impressive technicality(手工技艺), said Peter Keller, a geologist and president of the Bowers Museum in California, which is currently hosting an exhibit of some of these treasures.

The treasures came from a lost civilization, now known as the Sanxingdui, a city on the banks of the Minjiang River.

“It’s a big mystery,” said Keller, who is not involved in the current study.

“Archaeologists now believe that the culture disappeared sometime between 3,000 and 2,800 years ago,” Niannian fan, a river science researcher at Tsinghua University in Chengdu, China, said.

“The current explanations for why it disappeared are war and flood, but both are not very convincing,” Fan told Live Science.

But about 14 years ago, archaeologists found the remains of another ancient city called Jinsha near Chengdu. The Jinsha site, though it contained none of the bronzes of Sanxingdui, did have a gold crown covered with fish, arrows and birds similar to golden objects found at Sanxingdui. That has led some scholars to believe that the people from Sanxingdui may have relocated to Jinsha.

Fan wondered whether an earthquake may have caused landslides that dammed the river high up in the mountains and rerouted it to Jinsha. That catastrophe may have reduced Sanxingdui’s water supply, spurring its people to move.

And some historical records support their assumptions. In 1099 B.C., ancient writers recorded an earthquake in the capital of the Zhou Dynasty, in Shanxi Province, Fan said. Though that spot is roughly 250 miles from the historic site of Sanxingdui, the latter culture didn’t have writing at the time. So it’s possible the earthquake epicenter(震中) was actually close to Sanxingdui-but it just wasn’t recorded there.

Around the same time, geological sediment(沉积物) suggest massive flooding occurred, and the later-han Dynasty document The Chronicles of the Kings of Shu records ancient floods pouring from a mountain in a spot that suggests the flow being rerouted, Fan said.

Together, the findings hint that major earthquake triggered a landslide that dammed the river, rerouting its flow and reducing water flow to Sanxingdui, Fan said.

A Canine Reading Buddy

Dogs and people have developed a special bond over time. Recently, however, some dogs have taken a different role in people’s lives—therapy dogs.

1. Some therapy dogs visit patients in hospitals or nursing homes, while others visit children in schools and libraries. They are there to help children become better readers.

Reading programs that use therapy dogs have been in existence for more than ten years. All therapy dogs of this program are registered with an organization that tests the dogs to make sure they have the right personality for the job.

2. Both the dogs and the handlers are volunteers with the reading program.

At the start of a reading therapy session, a child and a dog are introduced. The pair is allowed to settle down in a quiet corner together. 3. An adult handler stays nearby but generally lets the dog perform its job without interfering(干涉). Sometimes, a handler may ask a question that encourages the child to work with the dog to help the child feel more comfortable.

Not every child will be able to be part of a reading therapy program that uses dogs. A few children might be allergic to dogs or afraid of them; some children might have cultural traditions that prevent them from touching a dog. 4.

Reading therapy programs inspire learning and change. 5. They spend time with human friends. For dogs that love human companionshiop and a quiet place to rest, being part of a reading therapy program can be a great way to spend a few hours each day. The readers benefit too, gaining confidence and learning that reading aloud can be a relaxing experience.

A. How do the therapy dogs benefit from it?

B. But therapy animals also serve in many other areas.

C. As the child reads, the dog usually lies quietly and listens.

D. When reading to an animal, some children may become relaxed.

E. In these circumstances, other animals are available, such as cats and parrots.

F. A therapy dog is more of a companion and is trained to help people in different ways.

G. A dog’s handler also takes a class and must pass a test to work in the therapy program.
