Tea bags
The modern version of tea bags first appeared in the Western World as early as 1903. Commercially, however, tea bags made their appearance around 1908,
However, people found that it was more convenient to brew tea
It’s generally advised to not squeeze a tea bag soaked in hot water. When you squeeze a tea bag, more tannins (鞣质) are released into the liquid. The result of this is that the drink becomes too bitter, or

4 . A Michigan farmer Bristle was digging with a backhoe (反铲挖土机) in one of his wheat fields when — bang — it struck a large bone.
Bristle contacted Fisher, a paleontology (古生物学家) professor at the University of Michigan. Fisher rushed to the farm and identified the bone as a fossil of an Ice Age mammoth (猛犸象). Since it was harvest season, Bristle gave Fisher and his students only one day to remove the rest of the fossils from the ground. The team found 20 percent of the animal’s bones, including its skull, tusks, pelvis, and shoulder blades as well as some teeth, ribs, and other bones.
The age of a mammoth can be determined by counting the rings in one of its tusks. Like the rings in a tree trunk, each ring stands for one year of a mammoth’s life. Fisher thinks that the bones are supposed to belong to male mammoth around forty years old. It was probably a rare hybrid of a woolly mammoth and a Colombian mammoth that lived between 11,700 and 15,000 years ago during the Pleistocene lee Age, when ice sheets covered much of Earth’s land.
The bones appeared to have been cut up and some of them were missing, leading Fisher to conclude that early humans must have killed the animal and stored its meat so they could return to it at a later time. Some other indications of human activity include a stone flake (薄片) that might have been from a cutting tool and the arrangement of the neck bones in order. If the mammoth had died naturally, its bones would have scattered randomly.
In the US, fossils found on private property belong to the owner of the land. However, Bristle donated the fossils to the University of Michigan for further study. Fisher hopes to display the bones at the University of Michigan Museum of Natural History, possibly combined with fiberglass models of bones from other Michigan mammoths to form a complete Mammoth skeleton (骨架).

5 . Researchers have found a group of lost cities in the Amazon rainforest. The cities were home to at least 10,000 farmers around 2,000 years ago.
Stéphen Rostain, one of the researchers, first noticed the earthen mounds (土墩) and buried roads in Ecuador more than twenty years ago. But at the time, he wasn’t sure how it all fitted together. Recent mapping using laser (激光) technology revealed those locations to be part of a group of settlements in the forested areas near the Andes mountains and connecting roads.
This LIDAR image provided by researchers in January 2024 shows complexes of rectangular (矩形) platforms arranged around low squares along wide dug streets at the Kunguints site, Upano Valley in Ecuador. “It was a lost valley of cities, and it’s incredible” said Rostain.
The Upano people lived in the settlements between around 500 B. C. and 300 to 600 A. D. That was around the same time period as the Roman Empire in Europe. Ancient people built on over 6,000 earthen mounds in an area surrounded by agricultural fields with drainage (排水) canals. The largest roads were 10 meters wide and went for 10 to 20 kilometers. While it is difficult to estimate populations, the area was home to at least 10,000 people, and possibly about 15,000 or 30,000 at its highest point. That is comparable to the estimated population of Roman-era London, then Britain’s largest city. The Amazon is often thought of as a wild area with only small groups of people. But recent discoveries have shown us how much more complex the past really is.
Scientists have recently also found evidence of complex rainforest societies that came before European contact elsewhere in the Amazon, including in Bolivia and Brazil. “There’s always been an incredible diversity of people and settlements in the Amazon, not only one way to live,” said Rostain. “We’re just learning more about them.”

9 . Globalization is a term used to describe how trade and technology have made the world into a more connected and interdependent place. Globalization also captures in its scope the economic and social changes tat have come about as a result
When did globalization begin?
Unquestionably, these types of exchanges were accelerated in the Age of Exploration, when European explorers seeking new sea routes to the spices and silks of Asia bumped into the Americas instead.
The web of globalization continued to spin out through the Age of Revolution, when ideas about liberty and equality spread like fire from America to France to Latin America and beyond.
With the Information Age globalization went into overdrive. Advances in computer and communications technology launched a new global era and redefined what it meant to be “connected.” Modern communications satellites meant the 1964 Summer Olympics in Tokyo could be watched in the United States for the first time.
A.Along with Chinese silk, Roman glass, and Arabian spices, many ideas and the secrets of paper- making also spread via these pathways of trade. |
B.This digital revolution massively impacted economies across the world as well: they became more information-based and more interdependent. |
C.It rode the waves of industrialization, colonization, and war through the eighteenth, nineteenth, and twentieth centuries, powered by the invention of factories, railways, steamboats, cars, and planes. |
D.The Silk Road, an ancient network of trade routes across China, Central Asia, and the Mediterranean used between 50 B. C. and 250 C. E. , is perhaps the most well-known early example of exchanging ideas, products, and customs. |
E.Trade and idea exchange now extended to a previously unconnected part of the world. |
F.Again, technology played an important role in the maritime trade routes that flourished between old and newly discovered continents. |
