2 . The ruins of a huge Maya city have been discovered in Guatemala with the help of the remote sensing technique LiDAR, according to the National Geographic on Thursday.

This breakthrough was possible thanks to LiDAR sensors, which can survey landscapes in 3D by reflecting laser pulses off the ground from unmanned air vehicles and others. LiDAR is exceptionally useful for detecting archeological sites (考古遗址), as it gets through jungles and other features that hold up exploration on the ground. The technique has been the activator (催化剂) of many discoveries in recent years. For instance, major finds at Angkor, Cambodia and Caracol, Belize can explain what it did.

This large lost city envelops sites like Tikal, Holmul, and Witzna—known for their temples and pyramids—but shows that these famous heritage areas are the tip of the iceberg of this lost urban network.

Hidden under the jungles of the Maya Biosphere Reserve, more than 60,000 human-made features—homes, canals, highways, some of which can even reach the modernized standard—have been identified by an international cooperation of researchers headed by the PACUNAM Foundation, a Maya cultural and natural heritage organization. Those have experts rethinking the outlines and complexity of the Maya empire.

These ancient peoples obviously established these imaginative cultures based on their known relics, but the new research has shown that the scale of this lost society is far beyond what experts had imagined. The findings will be explored in an hour-long documentary called Lost Treasures of the Maya Snake Kings, premiering (首映) Tuesday, February 6 on the National Geographic Channel.

“There are entire cities we didn’t know about now showing up in the survey data,” said Francisco Belli, one of the lead archeologists on the project. “There are 20,000 square kilometres more to be explored and there are going to be hundreds of cities there that we don’t know about, and we will push the frontiers,” he added.

1. What can we know about LiDAR?

C．It was first used in discovering a Maya city.	D．It’s a remote sensing technique using laser pulses.

2. What does the underlined word “Those” in paragraph 4 refer to?

A．The jungles of the Reserve.	B．The outlines of the Maya empire.
C．The researchers of the organization.	D．The man-made projects of the Reserve.

3. Which of the following words can best describe the Maya empire?

A．Famous and dangerous.	B．Vast and highly developed.
C．Mountainous and aggressive.	D．Enormous and traditional.

4. What do archeologists hope to do next?

A．Restudy the history of Maya.	B．Use the LiDAR sensors as usual.
C．Continue to explore the unknown.	D．Study the documentary more carefully.
