The secret of carrier pigeons' unbelievable ability to find their way home has been discovered by scientists: the feathered navigators follow the roads just like we do.
Scientists now believe the phrase "as the crow (乌鸦) flies" no longer means the shortest most direct route between two points. They say it is likely that crows and other day birds also choose AA-suggested routes, even though it makes their journeys longer.
Scientists at Oxford University spent 10 years studying homing pigeons using global positioning satellite (GPS) and got a surprising result. The birds often don't use the sun to decide their directions.
Instead they fly along motorways, turn at crossing and even go around roundabouts (绕道) , adding miles to their journeys.
"It really has knocked our research team sideways to find that after a decade-long international study, pigeons appear to ignore their inbuilt directional instincts (本能) and follow the road system," said Prof Tim Guilford, reader in animal behavior at Oxford University's Department of Zoology.
Guilford said pigeons use their own navigational system (导航系统) when doing long distance trips or when a bird does a journey for the first time.
"But once homing pigeons have flown a journey more than once, they can fly home on a habitual route, much as we do when we are driving or walking home from work," said Guilford.
"In short, it looks like it is mentally easier for a bird to fly down a road. They are just making their journey as simple as possible."

Across the United States, there are several places where two independent towns grew together to become one city — but kept both their names.

Winston?Salem is one of them. It’s a mid?sized city in what’s called the plateau(high land), between the Atlantic Coast and the inland mountains in the state of North Carolina. The Winston part is a relatively new place, founded early this century. It’s home to the nation’s biggest open?air tobacco market.?
The giant R.J. Reynolds Tobacco Company’s headquarters is in Winston?Salem, and Winston is the name of one of Reynolds’best?known cigarette brands. Fast?growing Winston soon surrounded the much older town of Salem, so in 1913, people in the area voted to combine them into a single place.?
From a historical and tourist point of view, Salem, or Old Salem, as it’s called today, is the interesting and unusual part of town.?
Salem was founded in the 1700s by the Moravians. They spoke German, and their community was religiously based, with single men and single women living apart in separate dormitories. The Moravians greatly valued women’s work and brainpower. In fact, one of the nation’s oldest boarding schools for young women— the Moravians’Salem Academy founded in 1772 — is still in operation. ?
Over the years, Salem lost its Moravian character. That all changed, though, when a nonprofit group began to rehabilitate the historic area. These days Old Salem is what’s called a living history museum, with exhibits, music, and tours of 18th-century houses, taverns and Moravian dormitory buildings just seven blocks from the tallest skyscraper in Winston-Salem.?
The historic community is booming again. Just as R. J. Reynolds is taking in millions of dollars making cigarettes across town, Old Salem is generating about S| 15 million a year in tourism revenue and donations.?
61. From the passage we can know that____________.?
A. Winston-Salem is the name of a city?
B. Salem is home to the tobacco market?
C. the city Winston-alem has two names?
D. Old Salem is the name of a tobacco brand
62. It can be inferred from Paragraph 3 that__________.?
A. the two cities benefited each other?
B. Salem developed faster than Winston?
C. R.J. Reynolds Company has moved into Salem?
D. the combination meets the wishes of the people
63. The city Salem is special for its__________.?
A. boarding school                          B. lifestyle and tradition?
C. respect for brainpower                     D. religious belief
64. The underlined word “rehabilitate” in Paragraph 6 is closest in meaning to “_________”.?A. reconstruct            B. evaluate         C. enlarge         D. decorate?
65. What will probably be talked about in the following part? ?
A. Some other attractions in Winston-Salem. ?
B. How Winston makes profits from tourism. ?
C. Other examples of cities combined by two parts.?
D. Something about the boarding school for women.
