The murals are about 1,350 years old. That's more than five times older than the United States. Scientists say the paintings belonged to the Mayas. That was a group of Native American people.

Scientists are excited about the discover because they don't know much about the Mayas daily life, explains Michael Coe, an expert on the Mayas. The paintings show how the Mayas worked, shopped and had meals.

"Mostly we get the murals that show gods and kings, never anything about the daily life, " Coe said. So far, scientists have found more than 30 murals in the pyramid. They are not sure why the Mayas created them. The experts hope to learn more as they continue their search. "We never had anything like this before," said Coe. "These are really special murals."

Scientists learned a lot about the Mayas from the murals. The Mayas were known for more than paintings. Now the murals tell us some fun facts about the Mayan way of life.

The "G" stands for the "generation" of your mobile network. 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data (數(shù)據(jù)) and the Internet, and 4G made all of these things faster. About 100 times faster than 4G networks, 5G will let people enjoy a faster Internet speed than ever before. This means that you will be able to download (下載) an HD movie in seconds with a short delay (延遲). But 5G won't just bring faster mobile Internet. People can use it for many other things as well.

With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to communicate in real time and avoid unexpected dangers. At the same time, 5G -enabled wearable devices (設(shè)備) will keep doctors know what is happening to their patients and let them know in time if there is something wrong. Besides, VR games will become more popular with 5G. The short delay of 5G will make the games feel even more real.

According to BBC, though 5G will make our lives more convenient, it will not be perfect. For one thing, 5G will not travel "far". On 4G networks, you can be 10 kilometers away from the nearest transmission base (傳輸基站) and seldom lose signal (信號). But 5G will only cover about 300 meters, meaning that we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new products exactly made for 5G that are expensive now.
