Big cats have existed on the earth for millions of years, though scientists aren’t sure exactly how long. But a new study indicates that a skull (颅骨) of a snow leopard (豹) relative that was recently unearthed is 4.4 million years old. That makes it the oldest big cat fossil (化石) ever found.
A team of US and Chinese scientists unearthed the skull in Tibet. This creature is not a direct ancestor to big cats, but it is closely related to the snow leopard, study leader Jack Tseng told the Associated Press. The fossil lends evidence to the belief that big cats existed in Asia and spread out from there.
Big cats are at the top of the food chain and have few predators of their own. Big cats include snow leopards, clouded leopards, tigers and lions. Based on genetic judgements, most scientists believe they first existed in Central Asia. But previously, the oldest known big cat fossil was 3.6 million years old and found in Africa.
The new fossil findings were published in the November 13 issue of the science journal Proceedings of the Royal Society B: Biological Sciences. Tseng and his team were fossil hunting in the Himalayas in 2010 when they discovered some bones, including the buried cat skull. The researchers were able to determine its age by studying the surrounding rocks and soil. The skull indicates that the animal was about the size of a clouded leopard, which can grow up to 50 pounds. In 2012, the team returned to unearth more cat bones.
David Polly from Indiana University told the Associated Press that the fossil is “convincingly older than the current record holder”. He added that there could be even older big cat fossils in the Tibetan plateau to uncover.
1.What does the newly unearthed skull prove?
A. Big cats might have their origins in Asia.
B. The oldest fossil is 4.4 million years old.
C. The snow leopard is the oldest big cat.
D. The skull is of big cats’ direct ancestor.
2.What does the underlined word in Paragraph 3 mean?
A. relatives. B. enemies.
C. partners. D. protectors
3.How do the researchers know the skull’s age?
A. By measuring its size and forehead.
B. By examining other bones around it.
C. By studying its chemical composition.
D. By exploring the rocks and soil around it.
4.Where was “the current record holder” in the last paragraph found?
A. Asia. B. Africa.
C. America. D. Australia.

According to the “Big Bang” theory, after settling into a solid globe, the earth exploded so 1.(violence) that it was not clear 2.the shape would last. Meanwhile, the explosion produced many gases, which were in time 3.(make) the earth's atmosphere. The continued presence of water appeared as the earth cooled down, making possible the 4.(develop) of life on the earth. Many millions of years later, with tiny plants 5.(multiply) on the surface of the water, green plants began to grow on land, 6.(follow) by insects, amphibians, reptiles and dinosaurs. After the age of the dinosaurs ended, all mankind, in 7.(it) turn, became the most important animals 8.the planet. Unfortunately, however, human beings put too much carbon dioxide into the atmosphere. As 9.result, the increasing heat from the sun was prevented from escaping into space. So whether life will continue on the earth 10.(remain) unknown.

For centuries, people wondered how big the Earth was. Unfortunately, although the Earth was flat, no one was able to figure out its size. Gradually, however, people began to realize that the Earth was really round.
Then, in the third century BC(2,300 years ago), a Greek man named Eratosthenes had an idea. Eratosthenes was sure that the Earth was a sphere. He used the sun and geometry(几何学) to figure out the size of the Earth. He calculated that the circumference(圆周) of the Earth was 28,600 miles(46,000 kilometers). The true size of the Earth is 25,000 miles(40,000 kilometers).
Eratosthenes’ measurement was wrong, but it was very close to the truth.
For many centuries after Eratoshenes lived, people made maps of the Earth. However, they did not know very much about the world outside of Europe, Asia, and North Africa. Mapmakers could not draw accurate maps of the Earth until people began traveling around the world in the fifteenth century, mapping small areas each time. In the eighteenth and nineteenth centuries, people began making correct maps of countries, but the first accurate maps of the world were not made until the 1890s.
Maps today are reliable(可依靠的), inexpensive, and easy to understand. People depend on maps every day. What would our lives be like without them?
1.A sphere is a ______.
A. large shape B. planet
C. ball shape D. member of the sun family
2.What’s a synonym(同义词) for “figure out”?
A. geometry B. calculate
C. make out D. understand
3.The first correct maps of the world were made_____________.
A. in the 15gth century B. in the 18th century
C. in the 19th century D. in the 20th century
4.When did map makers begin to draw correct maps of the Earth?
A. When people began to travel around the world
B. When people knew the size of the Earth
C. When people knew the shape of the Earth
D. Before people traveled around the world
