Scientists have been puzzled by the phenomenon that migrating birds fly not just in groups all the time, but in "V" formations and they have tried to figure out what benefit birds get from this particular formation. Now, a research group from University of London may have found the answer ― migrating birds fly in a "V" to save energy, according to a study published in the journal Nature.
When a bird flaps(振翅) its wings, it stirs the air around it and causes it to move indifferent directions. Scientist found in the study that the air creates an upward-moving wave at the tips of the wings, which means that if a bird flies around the wingtips of another bird, it can get a boost(抬高) from the rising air and therefore use less energy to stay in the air.
Apart form the "free ride" strategy, scientists were also surprised to observe that migrating birds timed their wing beats and adjusted their positions in a very precise way to maximize the lifting effect while avoiding areas where the air move downward.
"They're able to sense what's going on from the bird in front, where this 'good air' is coming from and now how to position themselves perfectly in it," lead researcher Steven Portugal told BBC.
In fact, the "V" formation has long thought to help birds fly more efficiently(效率搞地). A previous study showed that birds' heart rates went down when they were flying together in a "V" formation. Jet fighters were also found to be able reduce their energy use by up to 18% by staying near the wingtips of other jet fighters. Both of these findings led scientists to suspect that the "V" formation had an efficiency purpose, but until now they still lack proof.
"For scientists, the new study provides an insight into an interesting natural phenomenon. But it could mean even more for aircraft companies — helping them understand how they can imitate that with their plane formations to save fuel, said Portugal."

Big Ben, the landmark of London, a clock famous for its accuracy and chimes(和諧的鐘聲), stopped working for 90 minutes, an engineer said Saturday.
People do not know why the 147-year-old clock on the banks of the River Thames stopped at 10:07 p.m. Friday. It continued keeping time, but stopped again at 10:20 p.m. and remained silent for about 90 minutes before starting up again, a spokeswoman for the House of Commons said.
There has been speculation(推測) that a recent period of hot weather may have been to blame(責(zé)備). Temperatures in London reached 90 ℉on Saturday, and forecasters called it England’s hottest day in May since 1953.
The clock has experienced occasional problems. In 1962, snow caused the clock to stop before the New Year. In 1976, the clock stopped when a piece of its machinery broke. Big Ben also stopped on April 30, 1997, and once more three weeks later.
1.How many times has Big Ben stopped up to now?
A. Three B. Five C. Six D. Eight
2.The probable reason for Big Ben stopping working this time is ________.
A. high temperature B. low temperature
C. broken machine D. heavy snow
3.The passage mainly talks about ________.
A. Big Ben’s history
B. the solution to Big Ben’s problem.
C. the landmark of London

Does eating a good breakfast improve school study? A study of more than 1,000 pupils in the city of Lawrence suggests it does.
Youngsters who took part in the breakfast program improved their scores in the tests much more than those who didn’t. Among those who attended the program, fewer were found late for school than those who didn’t. And much fewer were found absent from their classes.
“Starting the day with a meal appears to be quite helpful,” says Amy Sampson, a research professor, who carried out the experiment on the students for a year.
Students who miss breakfast may be losing out on important nourishment in fruit, milk, bread and so on. If you are in a hurry in the morning, get you some pieces of bread with some fruit or yogurt. In that case, you won’t have to go to the selling machines for some chips or candy bars.
1.How many students in primary school are interviewed in Lawrence.
A.1000 B. over 1000 C. less than 1000 D.almost 1000

A. are clever than those who didn’t
B. are healthier than those who didn’t
C. were often late for school

A. the Lawrence City government B. teachers in a middle school
C. a professor D.1,000 pupils
