3 . 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.     1     One day, he got to the top of one tree and something caught his eyes. He looked out across the trees and saw the tops of some old buildings.

    2     He ran to tell the local governor excitedly, and together they walked into the jungle. There they found Tikal, the city that the Mayans had built, many hundreds of years before. The two men saw pyramids (金字塔), squares and houses.

For a long time before that day, local people had known that somewhere in the jungle there was an old Mayan city.     3     Between 200 and 900 AD, the city of Tikal had been the centre of Mayan civilisation (文明) in the area, but then the Mayans left it—nobody knows why! After 1000 AD, the jungle began to cover it.     4    

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.     5     Now the lost city had been found again, and people went there immediately to see it.

4 . Around the end of the first century AD, a Roman writer called Pliny wrote about a terrible volcanic eruption that he     1    (witness) as a young man. The eruption had occurred on August 24th, 79 AD. The tragedy left     2     deep impression on Pliny     3     had lost an uncle in the eruption. However, more than 1,600 years later, some     4    (science) found that the lost towns had been buried under the ash of Mount Vesuvius. Pompeii is like a “time capsule”     5    (preserve) a frozen moment in history.     6     the eruption occurred,     7     had been a booming Roman city with temples, markets, restaurants and theaters. Today you can visit these buildings by walking along the     8    (origin) streets of the city. And     9    (many) than 250 years since excavations started, thousands of tourists and hundreds of scientists visit Pompeii every year     10    (learn) more about the ancient world.

5 . Scientists have discovered a bit of hand-made string (线绳) that’s around 50,000 years old in Neanderthal remains. The first Neanderthal remains were found in the Neander Valley in Germany, which is where the name comes from. Neanderthals may have lived mainly in caves and made stone tools, but recent discoveries have given hints that Neanderthals developed some advanced skills that people used to think impossible. For example, Neanderthals knew how to make glue from the bark (树皮) of a tree.

Now, scientists report they’ve found a piece of string on a stone tool made by Neanderthals. Before this, the oldest known piece of string was one made by humans about 19,000 years ago. The string is about a quarter of an inch long. Almost all things made from plants during that time have broken down and disappeared, so it’s very special to find this bit of string.

The scientists don’t know whether the string was attached to the tool. But that doesn’t interest them as much as the fact that Neanderthals knew how to make string. Bruce Hardy, the lead scientist on the project, says that knowing how to make string was meaningful for humans. “We wouldn’t really be here today without that technology,” he says.

Making string is a very arduous process. This string was made from the inside bark of an evergreen tree. To make string that is strong enough, the string must be made of several smaller fibers twisted (缠绕) together in a special way. For the Neanderthal string, several fibers needed to be twisted together into something like yarn. Then three pieces of yam needed to be twisted together in the opposite direction to make the final string.

The scientists Aren’t sure what the string was used for, but they say that string like. the bit that was found could be used to make bags, baskets, traps, or other things. The researchers also suggest that because Neanderthals needed to make pairs and count fibers to make the string, the bit of string may also tell us something about the kinds of math that Neanderthals could do.

On the north bank of Fuxian Lake in Chengjiang County, Yunnan Province sits a straw-hat-shaped mountain     1     (call) Maotian Mountain,     2     a 512-hectare site is praised as a “world-class treasure trove of fossils” by the international scientific community. On July 1,1984, young paleontologists in China discovered a fossil of the arthropod (节肢动物化石) with a long tail in Maotian Mountain. “    3     we had studied in China were just shell of fossils. The arthropods, lifelike fossils with legs, which belonged to fossils of soft-bodied animals, are     4     game changer in the research of China’s paleontology (古生物学)”, Hou Xianguang, a paleontologist said.

Scientists have obtained a large number of research results on Chengjiang Fossil Site. The reason why Chengjiang fauna (动物群) is     5     great significance is that it is closely related to the emergence of the animal tree of life.

Up to now, more than 20 phyla and more than 280 species     6     (record)in the Chengjiang Fossil Site, of which, 80% are new species. On July 1, 2012, the Chengjiang Fossil Site     7     (be) inscribed on the World Heritage List by UNESCO,     8     (become) China’ s first World Heritage Site for paleontological fossils.

The UNESCO evaluation says the Chengjiang Fossil Site is one of the     9     (early) records of a complex marine ecosystem of the early Cambrian communities. The property displays excellent quality of fossil     10     (preserve). It presents an exceptional record of the rapid diversification of life on Earth during the early Cambrian period.

8 . A waterworks maintenance team discovered a possible one-of-a-kind Roman road in a field in Worcestershire that may date back 2,000 years.

If asked to name a place where you might make a once-in-a-lifetime archaeological (考古的) discovery, your mind may go to the pyramids of Egypt or the peaks of the Andes...not a field in Worcestershire. But a field in Worcestershire is exactly where workmen recently discovered what is thought to be a Roman road up to 2,000 years old！

The road was discovered during routine (常规的) waterworks maintenance by Severn Trent. Archaeological experts from Wychavon District Council were called to the scene and immediately recognised the find’s significance.

Wychavon District Council’s archaeology officer Aidan Smyth said, “When I first saw it, it took my breath away. If proven to be from the first century AD, it would be beyond rare.”

Experts say it is constructed in a traditional Roman technique, with similar roads only being found in Rome and Pompeii. Ruts (车辙) in the stones show that it was used by carts for a long time. A team from Historic England is expected to investigate further to determine the exact origin of the structure.

This is actually not the first significant historical discovery in Worcestershire. A number of possible forts have been suggested in Worcestershire since the 1950s, and Worcestershire is thought to possibly have been the site for the Roman town of Vertis.

It is too early to say without 100 per cent certainty that the road is Roman, but even if it is a road in the Middle Ages, it will still be a nationally significant discovery. If it is indeed a first-century Roman road, then it is the only one of its kind in Britain.

Discoveries made during the latest excavation of Pit No.1 at the Mausoleum of Qin Shi Huang, China’s first emperor, have allowed Chinese archaeologists to gain more insight into     1     the world-famous Terracotta Warriors and their weapons were made.

According to a recent report archaeologists     2     (restore) more than 140 Terracotta Warriors. They discovered that the arms of these figures were created separately and then attached to the bodies and covered in a layer of fine clay. The carving of fine details was completed     3     the arms were attached.     4     (additional), the pit has yielded a variety of weapons, including long-range attack weapons, shields for defense, as well as drums and drumsticks used for commanding soldiers.

“The Terracotta Warriors used a very special mechanism to connect pieces together. Such     5     (wise) was unique to China,” Lv Qiuxia,     6     expert on ancient Chinese art, told the Global Times on Wednesday. Lv added that the way the warriors were made differed based on their social status and class. “When     7     (analyze) how they were made, we noticed that the warriors were divided into different classes. This contributes to research     8     the burial culture of the Terracotta Warriors.” the expert noted.

Through excavations, Chinese researchers have established the types and arrangement of weapons     9     (use) by the Terracotta Warriors as well as the formations and patterns of the     10     (mystery) underground army.

10 . In 1879, an 8-year-old girl made a discovery that would rock our understanding of human history. On the walls of Altamira cave in northern Spain, she spotted amazing drawings of wild cows, painted in vivid red and black. More striking even than the images was their age: they were made thousands of years ago by modern humans’ supposedly primitive ancestors. Today, nearly 400 caves across Europe have been found decorated with hand stencils (模板), strange symbols and beautiful images of animals created by these skillful artists.

The discoveries led to the view that artistic talent arose after modern humans arrived in the region some 40,000 years ago, as part of a “cultural explosion” reflecting a flowering of the human mind. But more recent evidence has blown this idea out of the water. For a start, modern humans might not have been the first artists in Europe. What’s more, a collection of cave paintings emerging in Indonesia has dismissed the idea that Europe was the centre of creativity.

Local people have long known that the caves of the island of Sulawesi, Indonesia, contain many painted images. Modern humans are thought to have reached the region some 65,000 years ago, but nobody imagined the art could be very old because ancient paintings seem unlikely to survive in the environment of high temperatures. A team of researchers led by Maxime Aubert, now at Griffith University in Australia, upended this idea using a technique that is shifting our understanding of cave art. Using this technique in seven caves, they found a hand stencil was at least 39,900 years old, making it the oldest known hand stencil at that time.

This opened a floodgate to new discoveries in Indonesia. These included a hunting scene created at least 43,900 years ago, and by far the oldest descriptive artwork. “When we found that image, we were absolutely delighted, but when it turned out to be that old, we were almost jumping with joy,” says Adam Brumm, also at Griffith University.
