3 . The Nazca Lines are a collection of giant geoglyphs (地画), located in the Peruvian coastal plain about 250 miles south of Lima, Peru. Created by the ancient Nazca culture in South America, the 2, 000 year old Nazca Lines can only be fully viewed from the air given their massive size.
There are three basic types of the Nazca Lines: straight lines, geometric designs and pictorial (图画的) representations. More than 800 straight lines are found on the coastal plain, some of which are 30 miles long. Additionally, there are over 300 geometric designs, which include basic shapes such as triangles, rectangles, as well as arrows, zigzags and wavy lines. The Nazca Lines are perhaps best known for the representations of about 70 animals and plants, some of which measure up to 1, 200 feet long. Examples include a spider, hummingbird, monkey, whale, dog, duck, flower, and tree.
More recent research suggested that the Nazca Lines’ purpose was related to water, a valuable thing in the desert. The geoglyphs weren’t used as an irrigation system or a guide to find water, but rather as part of a ritual (仪式) to pray to the gods — an effort to bring much needed rain.
The Nazca Lines are located in the desert plains of the Rio Grande de Nasca river basin. The desert floor is covered in a layer of deep red color rocks. The ancient people created their designs by removing the top 12 to 15 inches of rock, revealing the lighter-colored sand below. They likely began with small scale models and carefully increased the models’ proportions (规模) to create the large designs.
Given the small amount of rain, wind and erosion in the desert, the geoglyphs have remained largely unharmed throughout the centuries. But the geoglyphs aren’t completely safe. In 2009, the Nazca Lines suffered the first recorded rain damage. Five years later, the environmental group Greenpeace damaged an area near the hummingbird geoglyph during a media stunt.

4 . Frozen in time, a 125-million-year-old mammal attacking a dinosaur. A 39-million-year-old whale, the heaviest animal that ever lived. The oldest known jellyfish, from 505 million years ago. Paleontology (古生物学) produces newsworthy discoveries.
Fossils (化石), moreover, provide direct evidence for the long history of life, allowing paleontologists to test hypotheses (假设) about evolution with data only they provide. They allow investigation of present and past life on Earth. Flows of biological diversity, appearances of new life forms and the extinctions of long existing ones, would go undiscovered without these efforts. But the headlines over exciting new fossils greatly underestimate the true importance of paleontology. Its real significance lies in how such discoveries brighten the grand history of life on Earth. From its beginnings, more than three billion years ago, to the present day, fossils record how life adapted or disappeared in the face of major environmental challenges.
Paleontologists provide us with a unique vantage on modern climate change. They play an essential role in interpreting ancient environments, in reconstructing ancient oceans, continents and climates. Fossils provide key limitation on the climate models that are essential for predicting future climate change. And the fossil record gives important insights into how life will respond to predicted future climate conditions, because these have occurred before in Earth’s history.
In addition, paleontology has provided a fundamental contribution to human thought: the reality of species extinction and thus of a world that has dramatically changed over time. In documenting the history of life, paleontologists recognized that many extinction episodes could occur suddenly, such as the event 66 million years ago that ended the dinosaurs. The search for the causes of past mass extinctions started pioneering studies from across the scientific spectrum (科学界), focusing on potential future threats to humanity.
Not only do paleontologists know what happens to life when things go bad, they also know how long it takes for ecosystems and biodiversity to recover from these disasters, which can take far longer than modern humans have existed.
Paleontologists thus provide a unique perspective on the nature and future long-term ecological impact of the current human-produced biodiversity crisis, the so-called Sixth Extinction, and therefore the importance of protecting modern biodiversity. The very concept of a Sixth Extinction would not exist without paleontologists documenting the first five.
Paleontologists know that understanding life’s past is critical to anticipating and adapting to life’s and humanity’s future. Paleontology is important because it brings its unique and critical perspective to current challenges in climate change, biodiversity loss and the environment. Paleontologists can predict the future because they know the past.

6 . Every year thousands of tourists visit Pompeii, Italy. They see the sights that Pompeii is famous for, like its stadium and theatres, its shops, and restaurants. The tourists do not, however, see Pompeii’s people. They do not see them because Pompeii has no people. No one has lived in Pompeii for almost 2,000 years.
Once, Pompeii was a busy city of 22,000 people. It lay at the foot of Mount Vesuvius, a grass-covered volcano. Mount Vesuvius had not erupted for centuries, so the people of Pompeii felt safe. But they were not.
In August of AD 79, Mount Vesuvius erupted. The entire top of the mountain exploded, and a huge black cloud rose into the air. Soon hot rocks and ash began to fall on Pompeii. When the eruption ended two days later, Pompeii was buried under 20 feet of stones and ashes. Almost all of its people were dead.
For centuries, Pompeii lay buried under stones and ashes. Then, in the year 1861, an Italian scientist named Ginseppe began to uncover Pompeii. Slowly, carefully, Ginseppe and his men dug. The city looked almost the same as it had looked in AD 79. There were streets and fountains, houses, and shops. There was a stadium with 20,000 seats. Perhaps the most important of all, there were everyday objects, which tell us a great deal about the people who lived in Pompeii. Many glasses and jars had some dark blue colour in the bottom, so we know that the people of Pompeii liked wine. They liked bread, too; metal bread pans were in every bakery. In one bakery there were 81 round, flat loaves of bread — a type of bread that is still sold in Italy today.
Ginseppe has died, but his work continues. One-fourth has not been uncovered yet. Scientists are still digging, still making discoveries that draw the tourists to Pompeii.

8 . Human footprints in White Sands National Park in New Mexico aroused an argument two years ago when scientists found the prints to be surprisingly old.
In 2021, researchers described more than 60 footprints preserved in New Mexico. Radiocarbon dating(放射性碳定年法)of an aquatic(水生的)plant’s seeds in and around the footprints suggested that the first humans in North America came from Siberia via a land bridge between 23,000 and 21,000 years ago, almost 7000 years earlier than the long-held theory.
But some scientists noted that the aquatic plants used to date the footprints could have absorbed ancient carbon in groundwater. “There’s a possibility then for the plant to give overstated viewpoints on its age,” says Davis, who wrote a criticism of the 2021 paper.
Now, two other ways probably solving the argument, researchers report in the Oct. 6 Science. Pigati and colleagues radiocarbon-dated pollen(花粉)stuck in the same layers as some of the footprints. The pollen came from land plants, mainly pine, avoiding the groundwater carbon issue. The researchers also collected stones above the lowest footprints and used a dating method that estimates how long the stones had been buried.
The pollen gave an age range of 23,400 to 22,600 years old, and the stone an age minimum of about 21,500 years old. Both results proved the previous age estimate. Despite possible errors in the individual dating methods, “the data overall from the new study strongly indicate human presence in the Americas” around 22,000 years ago, says Bente Philippsen, a physicist at the Norwegian University.
One thing is certain: There’s still plenty to uncover about the footprints.Coauthor Kathleen Springer says, “We are learning more every time we go out there,” she says. “This paper is literally the latest chapter in the White Sands story.”

9 . A city in the jungle
In the summer of 1848, in Guatemala, a man called Ambrosio Tut went out into the jungle (丛林), as he did almost every day. Tut was a gum (树胶) collector, looking for gum in the jungle.
For a long time before that day, local people had known that somewhere in the jungle there was an old Mayan city.
Seven years before Tut found Tikal, two British explorers had gone to Guatemala and had written a report about Mayan treasures in the jungle—but they hadn’t mentioned Tikal. Even earlier than this, local Indians had told people about a great city hidden in the trees, but no one had listened to them.
| A．But no one had seen it for centuries. |
| B．To do this, he had to climb the trees. |
| C．And then people forgot that it was there. |
| D．So they lost the chance to find the treasure. |
| E．Tut found many other treasures after that. |
| F．More and more scientists began to study the Mayan city. |
| G．Tut didn’t really know what he had seen but he knew it was something special. |
