金钥匙试卷系列答案The bar-tailed godwit(斑尾鹬) has just broken its own record for the world’s longest non-stop flight, including humans in planes, according to a report made by Lund University Press. The bird can fly non-stop for eight days, while the most impressive man-made airplane can only remain in the sky for 82 hours without a stop.
The bar-tailed godwit’s journey, from Alaska to New Zealand, covers over 6,835 miles. It completes this trip twice a year, in autumn going to New Zealand, and in spring back to Alaska. The tireless bird ends the trip without stopping once for food or rest. All other birds can only finish trips that are twice as short as what the bar-tailed godwit travels.
One reason for the bar-tailed godwit’s success is that it has made the best use of its fuel, which is only 0.41 percent of its body weight over each hour of any given long flight. Hedenstrom, a professor from Lund University, says, “This figure is extremely low compared with other birds.” The bird also has a special body shape that helps it fly easily. It stores body fat and protein to manage its trips. It also travels fast, compared to other birds and animals.
Many questions remain about this bird record holder that never gets lost in the air. Researchers wonder whether it has an inside compass(指南针) that helps it to know the direction. Please watch how beautiful bar-tailed godwits look as they come in for a landing, along with other birds.

Star hurdler Liu Xiang returned home last night after spending about three months in the United States for foot operation and recovery.
Liu and coach Sun Haiping were followed away by officials after arriving at Shanghai Pudong airport at around 6 : 30 p. m. , and said nothing to the waiting media.
Liu went straight to the Xinzhuang training base in Shanghai, where he will start on the comeback (恢复) through rehabilitation (复职) and training.
Feng Shuyong, vice-director of China's Athletics Administrative Center, said a group of experts is on standby at the training base to help with Liu's recovery.
"The experts will give Liu a full check-up tomorrow or the day after and advise regularly on rehabilitation in the coming months," Feng was quoted by qq. com as saying.
The foot injury forced defending champion Liu to quit from the 2008 Beijing Olympics last August after "he limped out of the Bird's Nest in the first round of the men's 110m hurdles, bitterly disappoint

The 25-year-old Athens Olympic and world champion had successful foot surgery in December at the Memorial Hermann-Texas Medical Center in Houston, and had four calcium deposits (钙物质) removed from his right Achilles tendon (跟腱).
He spent the next three months in Houston for rehabilitation and basic training under the guidance of doctors there.
"His recovery is better than we expected. Doctors believe that after three months' rehabilitation and training, he has actually achieved the level of recovery that generally needs four months," Feng said.
Liu will, however, be absent from the ongoing annual Chinese People's Political Consultative Conference (CPPCC) meeting due to the recovery process. Feng said Liu is paying close attention to the meeting through the Internet, and closely following issues such as athletes' education and life after retirement.
It is the second time Liu has asked for leave from the annual session after being elected to the CPPCC: He did not attend last y
