For photographers lacking training, experience and even the ability to click a shutter button, they produce remarkable pictures．Under the sea, deep in the woods and high in the sky, furry, feathery and leathery-skinned creatures are opening up vistas（远景）by taking cameras where no human can go．

This is the world of animal-borne imagine celebrated last month at a conference sponsored(supported) by the National Geographic Society for the 20th anniversary of its Crittercam, the device that started it all．

Since its debut（首次公开露面）in 1987 on the back of a turtle, the Crittercam and similar devices developed by others have grown smaller and more powerful．

“It’s more than just a camera now,” said Greg Marshall, the marine biologist and now filmmaker who invented the Crittercam．“We are now including more instruments to gather more data while at the same time reducing everything in size．”

The idea of attaching video cameras to animals came to Mr．Marshall in 1986 on a dive off Belize when a shark apporached him．When the animal quickly turned away, he noticed a shark with a sucker fish on its belly．He came up with the idea that putting a camera in place of the sucker fish would allow people to witness the shark’s behavior without disturbing it．

Crittercams have been attached to sharks, sea lions and other marine animals, and, more recently, to land animals．

Birds are a new addition, Mr．Marshall said．Dr．Christian Rutz of Oxford recently reported on tiny cameras called feathercams that monitor the crows in the South Pacific．It has discovered that crows are smarter than anyone knew they not only use twigs（嫩枝）and grass stems as tools to root out food, but they also save their favorite tools to use again．

Tracey L．Rogers, director of the Australian Marine Mammal Research Center in Sydney, said crittercam was a powerful tool in her work with leopard seals（豹斑海豹）in Antarctica．“In studying animals,” Dr．Rogers said at the meeting, “you want to see how our animal models align（与……一致）with reality．With a camera, you actually see what they do．You don’t have to guess．”

For the second time in three years, Norway's Robert Sorlie delivered a brave performance to win sled-dog racing's toughest contest—the Iditarod. The 47-year-old firefighter crossed the finish line in Nome, Alaska, at 8:39 a.m. local time Wednesday morning.

"It feels good to be here," he declared, after passing the finish line. "I'm ready for breakfast."

Frosty temperatures, rough land, and exhaustion couldn't break the musher （赶狗拉雪撬的人）, who completed the race in 9 days, 18 hours, 39 minutes, and 31 seconds. Runner-up Ed Iten finished 34 minutes later, and defending champ Mitch Seavey finished third.

Sorlie took his first lead at the 365-mile mark, but fell into second place halfway through the race. With 500 miles to go, he regained the lead for good.

Iditarod officials rewarded Sorlie with a generous prize of $72,066 and a new truck. But even more exciting for the winner was the historic nature of his ride. By winning this year's race, Sorlie joins a best group of mushers, becoming only the sixth person to win the Iditarod more than once.

After winning several major long-distance races in Europe, Sorlie made his Iditarod first appearance in 2002, finishing in ninth place. A year later, he returned to take on the Alaskan wilderness once again, and won.

Iditarod: A Quick History

Since 1973, the world's top competitors have gathered in Alaska to undertake the Iditarod's 1,150-mile trail, which stretches from Anchorage to Nome.

The race commemorates（纪念）a group of courageous mushers and dogs. In 1925, they traveled across part of the Idit trail to deliver serum（血清）to save sick children in Nome.

How many times has Robert Sorlie won the Iditarod?

       A．Once.     B．Twice.     C．Three times.          D．Several times.

How long did it take Ed Iten to finish the race?

       A．9 days, 19 hours, 13 minutes, and 31 seconds.

       B．9 days, 18 hours, 5 minutes, and 31 seconds.

       C．9 days, 18 hours, 39 minutes, and 31 seconds.

       D．9 days, 18 hours, 13 minutes, and 31 seconds.

This win was very important for Sorlie because he could _____.

       A．get the generous prize of $72,066 and a new truck

       B．get a chance to race in Europe

       C．join a best group of mushers

       D．save sick children in Nome

How long has the Iditarod been held?

       A．Only 3 years.   B．Over 100 years.       C．About 80 years.       D．Over 20 years.

【小题1】What’s the text mainly about?

For thousands of years, the most important two buildings in any British village have been the church and the pub. Traditionally, the church and the pub are at the heart of any village or town, where the people gather together to socialize and exchange news.
As a result, British pubs are often old and well preserved. Many of them have become historic sites. The most famous example is the pub in the city of Nottingham called “The Old Trip to Jerusalem”, which dates back to the year 1189 AD and is probably the oldest pub in England.
However, British pubs are not just for kings and queens; they welcome people from all classes and parts of society. On a cold night, the pub’s landlord or landlady can always find a warm place for you by the fire. There is always honest and hearty food and plenty of drink available at an affordable price.
That’s how things used to be. Things are beginning to change. It is said that the credit crunch(信贷紧缩) is causing 39 British pubs a week to go out of business. People do not have enough spare money to spend on beer. Recently, the UK government banned smoking in all pubs, and that may also have affected the number of customers going to pubs.
This decline is happening despite the fact that in 2005 the UK government started to allow pubs to stay open after 1l pm. Previously, with 1l pm as closing time, customers would have to drink quite quickly, meaning they sometimes got more drunk than they would if allowed to drink slowly. The British habit of drinking a lot very quickly is known as “binge drinking”, and it causes long-term health problems for people and problems with violent crime for communities.
In order to save their businesses, pubs are trying to change with the market. British pubs now offer something for everyone. A lot of pubs used to be “Working Men's Clubs”, meaning that women could not usually enter. Today, however, women can freely enter 99% of pubs without experiencing any problems. Perhaps things are changing for the better after all.
