Translate into Vietnamese: Humans were in America 100,000 years earlier than we thought, study claims The remains of a mastodon discovered during a routine excavation in California shows possible human activity in North America 130,000 years ago -- or about 115,000 years earlier than previously thought.

Paleontologists with the San Diego Natural History Museum discovered the remains of the elephant-like animal more than 20 years ago. But it wasn't until now that scientists were able to accurately date the findings, and possibly rewrite the history of the New World as we know it.

"This is a whole new ball game," Steve Holen, co-director of the Center for American Paleolithic Research and the paper's lead author, told CNN. The discovery changes the understanding of when humans reached North America. The study, to be published this week in the science journal Nature, said the numerous limb bones fragments of a young male mastodon found at the site show spiral fractures, indicating they were broken while fresh.

Con người đã ở Mỹ 100.000 năm trước đó hơn chúng ta nghĩ, nghiên cứu yêu cầu bồi thường
Những vẫn còn của một voi răng mấu phát hiện trong một cuộc khai quật thường lệ ở California cho thấy hoạt động của con người có thể ở Bắc Mỹ 130.000 năm trước--hoặc khoảng 115.000 năm sớm hơn so với trước đây nghĩ.
Marsh với San Diego Natural History Museum phát hiện phần còn lại của các động vật giống như con voi nhiều hơn 20 năm trước đây. Nhưng nó không cho đến bây giờ mà các nhà khoa học đã có thể chính xác ngày những phát hiện, và có thể viết lại lịch sử của Tân thế giới như chúng ta biết nó.

Hobbit-like Species of Humans

On the tiny island of Flores, east of Bali and midway between Asia and Australia, the scientists have discovered the remains of a small, hobbit-like species of humans. These people grew no larger than the modern three-year-old child. They lived about 18,000 years ago and are completely different species of human.

This discovery has taught scientists a lot about the human species. This remarkable discovery shows that the human species is more varied and flexible in its ability to adapt than previously thought. These hobbit-like people join a short list of other type of humans that lived with modern humans.

The researchers believe that these hobbits evolved from a normal size, human population that reached Flores around 840,000 years ago. One likely explanation is that, over thousands of years, the species became smaller because the environmental conditions favored a smaller body size. The dwarfing of mammals on islands occurs frequently. Islands limit food supply and predators and species compete for the same environmental space. Survival would depend on minimizing energy requirements.

The word “remains” in the passage is closest in meaning to _____.

A. pictures

B. descendants

C. fossils

D. records

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.

Scientists have discovered the bones of what may be the largest meat-eating dinosaur ever to walk the earth. The discovery was made by a team of researchers from Argentina and North America in Patagonia, a desert on the eastern slopes of the Andes in South America. Besides the interesting fact that the dinosaur was huge and horrifying, it is even more astounding that the bones of a number of the dinosaurs were found together. This discovery challenges the prior theory that the biggest meat-eaters lived as loners and instead indicates that they may have lived and hunted in packs. The Tyrannosaurus Rex lived in North America and was believed to hunt and live alone.

The newly discovered meat-eater appears to be related to the Giganotosaurus family, being as closely related to it as a fox would be to a dog. It is actually not of the same family at all as the Tyrannosaurus Rex, being as different from it as a cat is from a dog.

The fossilized remains indicate that the animals lived about 100 million years ago. With needle-shaped noses and razor sharp teeth, they were larger than the Tyrannosaurus Rex, although their legs were slightly shorter, and their jaws were designed to be better able to dissect their prey quickly and precisely.

The author states that the newly discovered dinosaur remains are evidence that it was the largest _________?

 

A. carnivorous dinosaur                             

B. dinosaur ever


 

C. South American dinosaur                      

D. herbivorous dinosaur
