Leaving Hanoi on a fiercely hot summer day,after an hour by air,Luang Prabang gradually appears below our airplane wings.From a few hundred meters above,my first impression of this UNESCO-listed heritage(遺產(chǎn))is an area of green land and mountains,surrounded by snaking rivers.
Encircled by mountains,the former royal capital of Luang Prabang is more than just the country's picture-perfect showpiece.
Travelers will be attracted to Luang Prabang by the city's timeless peacefulness with its shiny Buddhist temples, French colonial architecture and friendly people.
Tourists visiting Luang Prabang shouldn't miss the chance to see one of the most sacred(神圣的)Lao traditions, tak bat,or the Buddhist almsgiving ritual(儀式),which dates back to the 14th century.
As the sun rises in Luang Prabang,hundreds of Buddhist monks depart from their temples to gather their daily offerings,which most commonly are rice,fresh fruit and traditional sweet snacks.The daily alms gathering begins on the main street before spreading to all the side streets.
Our group of six got out of our comfy beds at 5 am to join other local residents and tourists to offer alms to the monks.We kneeled by the roadside in front of the 3 Nagas Hotel on the main street with big baskets of steamed sticky rice,waiting quietly until monks of all ages passed by to accept our gifts.
The daily ritual gives you a wonderful opportunity to experience an ancient Lao tradition.However,there are some strict rules if you wish to join the event.
Firstly,shoulders,chests and legs must be covered in modest clothing as a mark of respect.You should also remain a suitable distance from the monks.Photographs may be taken,but from a distance and never use a camera flash.The ritual has to be performed in silence.Talking to or touching the monks at any time,even when making an offering,is not allowed.
Another must-do morning activity is to visit the local market,where you can see the generosity that Mother Nature offers this dreamy land.While walking through the morning market,located within a long and narrow hamlet,I was excited to see all kinds of products from the nearby river and jungle: some ill-fated squirrels lying next to fresh bamboo shoots,different kinds of wild mushrooms and vegetables displayed on banana leaves and giant river catfish in baskets.
Although Luang Prabang is small,there are many things to see here.Active travelers can get up close and personal with Laos' gentle giants at the elephant conservation camp or take in some scenes of riverside life with a cruise or kayak excursion on the rivers.Two waterfalls that are perfect for picnicking in the foothills nearby,and classes are available in traditional crafts.

Spring soccer season is under way, and many youth leagues are playing under new safety rules. In November, the US Soccer Federation said that players on its teams who are 10 or younger are no longer allowed to head the ball Players ages 11 to 13 have limits on how often they can practice heading. The new rules are made to prevent kids from getting concussions (腦震蕩)—injuries caused by a blow to the head that shakes the brain. Common problems include headaches and dizziness. Severe concussions can lead to long brain damage.
Heading the ball can be one of the riskiest parts of soccer. Sometimes the force of hitting the ball with their heads gives players concussions. But more often, players receive concussions when they accidentally knock heads with other players and hit their heads on the grass. “More concussions happen during the act of heading than any other action in soccer,” explains Dr. Robert Cantu, an expert on brain injuries.
So far, the new rules are made only to teams that are part of the US Soccer Federation. But the group says it hopes other leagues will soon follow its example.
Former US soccer star Brandi Chastain is one of the leaders of the activity to ban heading in youth soccer. She applauds the rule change. Last month, Chastain showed her determination of learning more about the effects of heading when she promised to donate her brain to science after she dies.
“If there’s any information to be gathered on the study of someone like me,who has played soccer for 40 years, it feels like my responsibility,” Chastain told The New York Times.
1.What can we learn from the first two paragraphs?
A. Players needn’t take the risk of heading the ball in soccer.
B. All of the players, headaches result from hitting heads on the grass.
C. Players must receive concussions when knocking heads with other players.
D. The act 0f heading can cause more concussions than other actions in soccer.
2.What is Brandi Chastain’s attitude towards the new safety rules in playing soccer?
A. Unconcerned. B. Positive.
C. Negative. D. Doubtful.
3.From the text, we can learn .
A. Brandi Chastain suffers from very severe concussions
B. concussions caused by heading the ball can not be healed
C. Brandi Chastain is willing to devote herself to the security of soccer players
D. the new rules in soccer have been carried out among all of the American leagues
