Using modern technology, archaeologists (考古学家) have recently discovered about 200 Mayan artifacts (玛雅古器) in Mexico, which surprisingly, appear to have been untouched for up to 1,000 years. The artifacts were found inside a cave in ruins of the ancient Mayan city of Chichen Itza on Mexico’s Yucatan Peninsula.
The lead researcher on the project is Mexican archaeologist Guillermo de Anda. He called the cave a “scientific treasure”.
The findings included bone pieces and burnt offering materials. In addition, incense burners, vases, plates and other objects were discovered. Some items included the portrait of Tlaloc, the rain god of central Mexico.
The cave where the objects were found is so unique. It is part of a cave system known as Balamku. The cave is long, narrow and dark. It is about three kilometers east of the main pyramid of Kukulkan. It sits at the center of Chichen Itza which is the stone city described by the United Nations as “one of the greatest Mayan centers of the Yucatan Peninsula.”
The cave sits about 24 meters underground, with areas connected by passages. Some of the passages were so narrow that researchers had to climb in or pull themselves through. The team has so far explored about 460 meters of the cave, and is unsure how far it stretches. The team plans to continue exploring the cave. The found artifacts will not be removed, but studied inside.
The team accidentally found the artifacts while exploring Chichen Itza in an effort to learn more about its underground water system. The new discovery will help scientists better understand the history, culture, lives and beliefs of people who lived in Chichen Itza, especially in the boom years.
Archaeologists believe there may be another cave hidden under the pyramid of Kukulkan that could be connected to the latest find. “Let’s hope God will lead us there,” Guillermo de Anda said. “That is part of the reason why we are entering these sites to find a connection to the natural well under the Kukulkan.”
1.What’s amazing about the Mayan artifacts discovered in Mexico?
A.The long history and perfect state.
B.The digging time and location.
C.The current high price.
D.The variety of usage.
2.What is paragraph 4 mainly about?
A.The features of the cave. B.The findings in the cave.
C.The ancient cave system. D.The origin of Mayan centers.
3.What is the significance of the new discovery?
A.It can help scientists register cultural relics.
B.It can encourage archaeologists to form work beliefs.
C.It can help scientists further learn about Mayan civilization.
D.It can arouse the interest of Mexicans in archaeology.
4.What will archaeologists do next according to the last paragraph?
A.Dig wells under the Kukulkan.
B.Move the findings to another cave.
C.Find the cause of groundwater disappearance.
D.Try to find another cave under the pyramid of Kukulkan.

ARCHAEOLOGISTS(考古学家) GUIDED BY laser images of a remote region of northern Guatemala have discovered 20-foot-high walls, watchtowers, and other evidence that ancient Maya societies had been annoyed by warfare threat over many years. The finds have upended long-established impressions of a civilization that it tamed the jungle and built thriving cities,then declined and disappeared quietly beneath the dense tropical forest.
Among the most surprising discoveries was a large stone complex now called La Cuemavilla. Built on a steep ridge, the heavily fortified site included high walls. Moats which serves as the largest defensive system ever discovered in the region.
This was surprising says an archaeologist, "because we had a tendency to romanticize Maya warfare as something that was largely ritualized. But the fortifications were seeing suggest an elevated level of antagonism over centuries. Rulers were so deeply alarmed that they felt the need to invest in all these hilltop fortifications. There is an almost visible sense of fear in this landscape.
All these findings owe credit to PACUNAM LIDAR Initiative, a laser survey of some 800 square miles of the Maya Biosphere Reserve in northern Guatemala. Using revolutionary Laser technology, the survey revealed the long-hidden ruins of a sprawling pre-Columbian civilization that was far more complex and interconnected than most Maya specialists had supposed.
Guided by the new Laser treasure maps, the LIDAR team deployed through the jungle over the past year to conduct hands-on investigations of more than a dozen of the most promising sites-most of which would have been imperceptible without LIDAR.
"You could walk over the top of a major ruin and miss it, "says an archaeologist who's part of the PACUNA project. But LIDAR picks up the patterns and makes the features pop out with surprising clarity.
Three-dimensional maps generated by the survey yielded surprises even at Tikal, the largest and most extensively explored archaeological site in Guatemala. The ancient city was at least four times bigger than previously thought, and surrounded by a massive ditch and fortified base stretching for miles.
Archaeologists stress that LIDAR, for all its utility, will never see below the ground or yield direct dates of occupation. “we still need to dig and hack our way through the jungle, but now we have a very accurate map to guide us.
1.How did people think of Maya before the discovery of the defense ruins?
A. It was the most advanced civilization in the history of mankind.
B. It was long under the threat of large-scale wars
C. Its rise and decline were under way peacefully
D. It was finally destroyed by a large-scale war

B. The new laser technology was mainly used to enlarge the original site size.
C. The LIDAR helps to avoid the traditional digging task in site exploration.
D. The Tikal site was found to be protected by certain defense works

Police recently caught the suspected Golden State Killer using a tool they could only have dreamed of decades ago, when a shocking series of murders shook California: a database filled with people’s genetic data (基因数据).
Police used an open-source database called GEDmatch to find relatives who matched genetic material taken from an old crime scene, then worked backward to identify and catch 72- year-old former police officer Joseph James DeAngelo.
GEDmatch’s 950, 000 users voluntarily upload and share their genetic information, making it accessible to others who share their own data — including law enforcement (执法). More than a dozen other similar platforms also exist. “If your relatives have contributed and you are part of even a family tree that appears online in one of these shared resources, you can be indirectly tracked through the combination of their DNA and the publicly available family history,” says Dr. Robert Green, a medical geneticist at Harvard Medical School.
Data sent to commercial companies like 23andMe, which has over 5 million customers, is much tougher for outsiders to access, but the case has still highlighted the issue of genetic privacy.
Although many genetic-testing companies have been asked to cooperate with legal investigations (调查), and clearly warn customers of this possibility, not all requests are honored. “23andMe has never given customer information to law-enforcement officials, ” a company representative told TIME.
The risks of keeping such sensitive data private are high. The potential for abuse exists; for example, insurance companies could theoretically use genetic data to refuse coverage (保险项目), Green says. But the systems in place to prevent misuse appear to be working. One is the Genetic Information Nondiscrimination Act, a 2008 law that protects consumers from employment and insurance discrimination related to genetics. As long as that’s the case, Green says, the good of genetic tests outweighs the bad.
Sharon Zehe, a lawyer for the department of laboratory medicine and pathology at the Mayo Clinic, takes a more cautious approach. “Family tree services can be fun, but make sure you are using a reputable organization that has strong privacy policies in place, ” she says. “Genetic data is biologically as important as a fingerprint.”
1.Who is the Golden State Killer?
A. Robert Green. B. Joseph James De Angelo.
C. The author. D. Sharon Zehe.
2.What drives the users to upload their genetic data?
A. The Police’s force. B. Their relatives’ advice.
C. The boss’s order. D. Their own willingness.
3.Who might misuse customers’ genetic data?
A. The police. B. GEDmatch.
C. Insurance companies. D. 23andMe.
4.What is the main idea of the text?
A. Genetic data is equal to a fingerprint.
B. A 72-year-old killer was put into prison.
C. Murders causes concern for genetic privacy.
D. Genetic information is shared on the Internet.

Recently scientists have worked out a way to judge roughly where a person has lived using strands(缕) of hair, a technique that could help track the movements of criminal suspects or unidentified bodies .
The method depends on measuring how chemical variations in drinking water show up in people’s hair.
While U.S diet is relatively identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as clouds move.
Most hydrogen and oxygen atoms in water are stable , but traces of both elements are also present as heavier isotopes (同位素) . The heaviest raid(列阵)falls first. As a result, storms that form over the Pacific deliver heavier water to California than to Utah.
Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can establish a geographic timeline. Each inch of hair corresponds to about two months.
Cerling’s team collected tap water samples from 600 cities and constructed a frame of the regional differences. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops. They were able to accurately place the hair samples in broad regions roughly corresponding to the movement of raid systems.
“It’s not good for pinpointing (精确定位),” he said. “It’s good for ruling out many possibilities.”
1.What can we learn from the passage about the latest discovery?
A. One’s hair growth has to do with the amount of water they drink.
B. A person’s hair may reveal where they have lived.
C. Hair analysis identifies criminal suspects accurately.
D. The chemical composition of hair varies from person to person.
2.What does the underlined word “identical” in paragraph 3 probably mean?
A. similar B. fantastic C. beneficial D. healthy
3.What is the practical value of Cerling’s research?
A. It helps analyze the quality of water in different regions.
B. It helps the police determine where a crime is committed.
C. It helps the police narrow down possibilities in detective work.
D. It helps identify the drinking habits of the person under investigation.
