Thus we are sometimes affected by fears or anxiety impacting our life. For as long as I could remember I had struggled with anxiety.

AWhen people first walked across the Bering Land Bridge thousands of years ago, dogs were by their sides, according to a study published in the journal Science.Robert Wayne of the University of California, Los Angeles, and Jennifer Leonard of the Smithsonian Institute, used DNA material—some of it unearthed by miners in Alaska—to conclude that today’s domestic dog originated in Asia and accompanied the first humans to the New World about 10,000 to 15,000 years ago. Wayne suggests that man’s best friend may have enabled the tough journey from Asia into North America. “Dogs may ha ve been the reason people made it across the land bridge,” said Wayne. “They can pull things, carry things, defend you from fierce animals, and they’re useful to eat.”Researchers have agreed that today’s dog is the result of the domestication of wolves thousands of years ago. Before this recent study, a common thought about the precise origin of North America’s domestic dog was that Natives domesticated local wolves, the descendents of which now live with people in Alaska, Canada, and the Lower 48.Dog remains from a Fairbanks-area gold mine helped the scientists reach their conclusion. Leonard, an evolutionary biologist, collected DNA from 11 bones of ancient dogs that were locked in permafrost until Fairbanks minersuncovered them in the 1920s. The miners donated the preserved bones to the American Museum of Natural History in New York City, where they remained untouched for more than 70 years. After borrowing the bones from the museum, Leonard and her colleagues used radiocarbon techniques to find the age of the Alaska dogs. They found the dogs all lived between the years of 1450 and 1675 A.D., before Vitus Bering and Aleksey Chirikov who were the first known Europeans to view Alaska in 1741. The bones of dogs that wandered the Fairbanks area centuries ago should therefore be the remains of “pure native American dogs,” Leonard said. The DNA of the Fairbanks dogs would also expose whether they were the descendents of wolves from North America.Along with the Fairbanks samples, the researchers collected DNA from bones of 37 dog specimens from Mexico, Peru, and Bolivia that existed before the arrival of Columbus. In the case of both the Alaska dogs and the dogs from Latin America, the researchers found that they shared the most genetic material with gray wolves of Europe and Asia. This supports the idea of domestic dogs entering the New World with the first human explorers who wandered east over the land bridge.Leonard and Wayne’s study suggests that dogs joined the first humans that made the adventure across the Bering Land Bridge to slowly populate the Americas. Wayne thinks the dogs that made the trip must have provided some excellent service to their human companions or they would not have been brought along. “Dogs must have been useful because they were expensive tokeep,” Wayne said. “They didn’t feed on mice; they fed on meat, which was a very guarded resource.”（1）The underlined word “remains” is closed in meaning to ______.A . leftover foodB . animal wasteC . dead bodiesD . living environment（2）According to the study described in Paragraph 4, we can learn that ______.A . ancient dogs entered North America between 1450 and 1675 ADB . the11 bones of ancient dogs are not from native American dogsC . the bones discovered by the gold miners were from North American wolvesD . the bones studied were not from dogs brought into North America by Europeans （3）What can we know from the passage?A . Native Americans domesticated local wolves into dogs.B . Scientists discovered some ancient dog remains in 1920s.C . Latin America’s dogs are different from North America’s in genes.D . Ancient dogs entered North America across the Bering Land Bridge.（4）The first humans into the New World brought dogs along with them because ______.A . dogs fed on miceB . dogs were easy to keepC . dogs helped protect their resourcesD . dogs could provide excellent service（5）What does the passage mainly talk about ______.A . the origin of the North American dogsB . the DNA study of ancient dogs in AmericaC . the reasons why early people entered AmericaD . the difference between Asian and American dogs3. 阅读短文，完成下列问题。
