阅读理解 Red pandas are native to the high forests of Asia. They are only a little bigger than a house cat and considered to be endangered. Scientists reported last month that not all red pandas belong to the same species. There are two different species of this animal, not just one, a study found. The scientists reported finding major differences in three genetic markers between Chinese red pandas and Himalayan red pandas. Scientists identified the markers after studying DNA from 65 of the creatures. DNA carries genetic information for the development, growth and reproduction of living things. Recording the existence of two separate species could help guide efforts for protecting red pandas, scientists added. "Chinese red pandas live in northern Myanmar, as well as southeastern Tibet, Sichuan, and Yunnan provinces in China. Himalayan red pandas are native to Nepal, India, Bhutan and southern Tibet in China," the researchers said. Researchers Yibo Hu and Fuwen Wei led the study. Their findings appeared in the magazine Science Advances. Scientists had earlier suggested there were two species of red panda. But the new study was the first to provide the genetic information necessary to allow such a judgment. International experts guess a total population of around 10,000 red pandas in the wild. The two species differ in color and skull shape. The Himalayan red panda is the less of the two. Major threat stored pandas include deforestation and habitat loss. While they have similar names, red pandas and giant pandas are not closely related. Giant pandas are one of the world's eight bear species. Red pandas are sometimes called living fossils because they have no close living relatives. They are the only remaining member of their mammalian family. （1） What played a key role in telling the two kinds of red pandas apart? A . Life habits. B . Body sizes. C . Living places. D . High technology. （2） What do we know about the research result? A . It proved a nearly guess. B . It figured out the number of red pandas. C . It found two similar species of red panda. D . It proved one species of red pandas was endangered. （3） What can be inferred from the last paragraph? A . The red panda's habitat needs changing. B . Red pandas and pandas have little in common. C . Red pandas are one of the world's bear species. D . Red pandas are less than pandas in number. （4） What can be the best title for the text? A . Red Pandas Are Mistaken for Giant Pandas B . Red Pandas Are Becoming Endangered C . Red Pandas Have Actually Two Different Species D . Red Pandas Are More Precious than Giant Pandas 答案： D A B C
