3 . In ancient Maya civilization, cacao — which chocolate is made from — wasn’t just for the elites (精英). Traces of the sacred plant show up in antiques from all types of neighborhoods and in and around a former Maya city, researchers report in the Proceedings of the National Academy of Sciences. The finding suggests that, contrary to previous thinking, cacao was consumed at every social level of Maya society.
“Now we know that the ceremonies with cacao were likely played out by everyone,” says AnabelFord, an archaeologist at the University of California, Santa Barbara. Cacao was sacred to the ancient Maya, consumed in ceremonies and used as a currency. The cacao tree itself was linked to Hun Hunahpu, a Mayan god. Previous research found cacao in burials (墓地), suggesting that its use was restricted to those at the top.
To explore the extent to which cacao was used in broader Maya society, Ford and colleagues examined 54 antiques dating from A. D. 600 to 900. The antiques come from jars, mixing bowls, serving plates and vases thought to be drinking vessels. All the pieces were found in residential and ceremonial civic areas of varying size and status from city centers, foothills, upland areas and the valley around the former Maya city of El Pilar, on the present-day border of Guatemala and Belize.
To identify cacao, the researchers searched for theophylline, a compound found in trace amounts in the plant. The team found the compound on more than half of the samples, on all types of antiques and distributed throughout social contexts.
Future research will move beyond who consumed cacao and explore the role of farmers in managing the critical resource. “A better question is to understand who grew it,” Ford says, because those people probably had greater access to the valuable commodity.

4 . When Howard Carter opened King Tut’s tomb (墓穴), it was full of gold and other valuables. When he and his team then attempted to remove King Tut’s mummy (木乃伊), they did a great deal of damage to the mummy while removing it.
Decades later, in 1968, experts conducted an examination of King Tut’s mummy using simple X-ray technology. Three important discoveries led to various theories about his death. First, the X-rays showed that bones in Tut’s chest were missing. Some guessed the damage was caused by a war injury or an accident. Plus, there was a small hole in the back of the skull (头骨), and pieces of bone inside it, causing many to believe that Tut was killed by a blow to the back of the head. Was he murdered by people wanting to take control of Egypt? Finally, a serious broken bone was discovered on Tut’s left leg. Tut was hurt a few hours before his death. This could have been the result of an accident. Could an infection from the injury have killed Tut?
In 2005, scientists under the direction of Zahi Hawass used new X-ray technology to study the mummy. They discovered that the damage to Tut’s chest was caused by Howard Carter, and the hole in Tut’s skull was made when the body was gotten ready for burial. While this ruled out the theory of murder, it still doesn’t tell us exactly how he died.
Then, in 2008, when Hawass and his team analyzed the DNA of the mummies and other tombs nearby, they made some shocking discoveries. They found Tut’s father and mother, who had similar DNA, were actually brother and sister. The DNA they passed on to Tut may have made it easy for him to catch a disease. Did an infection that started in his broken leg cause his death? No one knows for sure. But Hawass and his team hope they will someday have an answer to this age-old mystery.
1. Why was the examination of King Tut’s mummy conducted in 1968?A.To determine the cause of Tut’s death. | B.To assess the condition of Tut’s coffin. |

A.Tut’s broken leg had little to do with his DNA. |
B.Tut’s DNA features might have been common. |
C.Tut’s death was closely connected to their DNA. |
D.Tut’s health was probably affected by their shared DNA. |
