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."
1.What would be the best title of the passage?
A. How Pigeons Find Their Ways Home? B. Why Pigeons Can Fly long Distance?
C. Birds Follow Roads as We Do. D. Why Crows Fly the Shortest D stance?
2.What does the words "the feathered navigators" refer to?
A. The crows. B. The pigeons. C. Day birds. D. Animals that can fly.
3.Scientists used to think that homing pigeons often find their directions ____.
A. by global positioning satellite B. by the sun
C. by the road system D. by following other birds
4.Why do homing pigeons tend to follow the road system daring the r journey?
A. Because they don't have their inbuilt directional instincts now.
B. Because their own navigational system doesn't work.
C. Because it is too hard to use their own navigational system.
D. Because it is easier to make journey simple by following road system.

Passenger pigeons（旅鸽）once flew over much of the United States in unbelievable numbers. Written accounts from the 18th and 19th centuries described flocks（群）so large that they darkened the sky for hours.
It was calculated that when its population reach its highest point, there were more than 3 billion passenger pigeons – a number equal to 24 to 40 percent of the total bird population in the United States, making it perhaps the most abundant birds in the world. Even as late as 1870 when their numbers had already become smaller, a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati.
Sadly, the abundance of passenger pigeons may have been their undoing. Where the birds were abundant, people believed there was an ever-lasting supply and killed them by the thousands. Commercial hunters attracted them to small clearings with grain, waited until pigeons had settled to feed, then threw large nets over them, taking hundreds at a time. The birds were shipped to large cities and sold in restaurants.
By the closing decades of the 19th century, the hardwood forests where passenger pigeons nested had been damaged by Americans’ need for wood, which scattered（驱散）the flocks and forced the birds to go farther north, where cold temperatures and spring storms contributed to their decline. Soon the great flocks were gone, never to be seen again.
In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons, but by then, no sizable flocks had been seen in the state for 10 years. The last confirmed wild pigeon in the United States was shot by a boy in Pike County, Ohio, in 1900. For a time, a few birds survived under human care. The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden in September 1, 1914.
1.In the 18th and early 19th centuries, passenger pigeons _______.
A. were the biggest bird in the world
B. lived mainly in the south of America
C. did great harm to the natural environment
D. Were the largest population in the US
2.The underlined word “undoing” probably refers to the pigeons’ _______.
A. escape B. ruin C. liberation D. evolution
3.What was the main reason for people to kill passenger pigeons?
A. To seek pleasure. B. To save other birds.
C. To make money. D. To protect crops.
4.What can we infer about the law passed in Michigan?
A. It was ignored by the public. B. It was declared too late.
C. It was unfair. D. It was strict.

Liverpool city council want to clear the city of fat pigeons. They say that people are feeding the birds, which makes them fat. The pigeons get bigger because their normal diet would consist of seeds and insects, not high-fat junk food they are eating in the city centre.
The council want people to know that everyone who feeds the pigeons is responsible for the streets being so crowded with these birds. They hope to encourage the birds to move away from the city centre and into parks and open spaces.
Ten robotic birds have been brought into the city centre to scare the pigeons away and visitors are asked not to give the pigeons any food. The mechanical birds－known as "robops"－will sit on the roofs of buildings. They can be moved around to different locations. They look like a peregrine falcon, which is a bird that kills pigeons. They even make noises and flap their wings to scare the pigeons. They hope that the pigeons will go away before the city becomes the European Capital of Culture in two years.
