It was the summer of 1936．The Olympic Games were being held in Berlin．I had trained, sweated and disciplined myself for 6 years on the running broad jump．A year before, as a college student at the Ohio State, I'd set the world's record of 26 feet 8 1/4 inches．Nearly everyone expected me to win．
I was in for a surprise．When the time came for the broad-jump trials(选拔赛), I was shocked to see a tall boy hitting the pit （坑） at almost 26 feet on his practice leaps．He turned out to be a German named Luz Long．He had easily qualified for the finals on his first attempt．
A nervous athlete is an athlete who will make mistakes．I fouled （犯规）twice on my qualifying jumps．Walking a few yards from the pit, I kicked at the dirt disgustedly．Suddenly I felt a hand on my shoulder．I turned to look into the friendly blue eyes of Luz Long．"Hi, I'm Luz Long．I don't think we've met．" "Glad to meet you," I said．Then, trying to hide my nervousness, I added, "How are you?" "I'm fine．Something must be eating you．You should be able to qualify with your eyes closed．" He said．
He seemed to understand my nervousness, and took pains to reassure me．Finally, seeing that I had calmed down somewhat, he said, "What does it matter if you're not the first in the trials? Tomorrow is what counts．" All the tension left my body as the truth of what he said hit me．Confidently I qualified with almost a foot to spare．
Luz broke his own record and pushed me on to a peak performance．The instant I landed from my final jump—the one which set the Olympic record of 26 feet 5 1/16 inches—he was at my side, congratulating me．

TANG Dynasty writer Du Mu once wrote in a poem titled Qingming: "The ceaseless drizzle drips all the dismal day; So broken-hearted fares the traveler on the way.Where can a wine house be found to drown his sadness ?A cowherd points to Almond Flower (Xing Hua) Village in the distance."
Qingming, the traditional tomb-sweeping day on the Chinese lunar calendar, falls on April 4 this year. Qingming Jie was proclaimed（正式宣布） a Chinese national holiday in 2008. It is a time for remembering loved ones who have departed (去世). People visit their ancestors’ graves to sweep away the dirt and get rid of any weeds. They also leave offerings (祭品) of food and flowers, and burn incense (香) and paper money. Chinese tombs are usually built in the woods or on mountains, far from the city. It is believed that an area that faces south, with many pine trees, is a proper place for a tomb. People believe such a place will make the ancestors happy, and in return, they will look after the living family.
Nowadays, more and more residents are choosing environmental-friendly ways to spend the holiday such as flower sacrifices and memorial ceremonies on the Internet or at home. As one of the traditional ways to celebrate Tomb-sweeping Day – burning paper or incense – isn't exactly good for air quality
In contrast to the sadness of the tomb sweepers, people also enjoy hope of Spring on this day. The Qingming Festival is a time when the sun shines brightly, the trees and grass become green and nature is again lively. Since ancient times, people have followed the custom of Spring outings. At this time tourists are everywhere
Many people fly kites on Tomb Sweeping Day. They are usually made from a bamboo crossbow with coloured paper. The kite vibrates and buzzes as it rises into the sky, counterbalanced by its tail. Large kites can be as broad as three metres across, with a tail of six to ten metres. Most kites have a rectangular shape, and many have patterns of crabs, centipedes, butterflies, dragonflies, or Chinese characters such as "good fortune" or "long life".
1.What’s the main idea of the second paragraph?
A．The cultural difference between the east and the west.
B．The traditional customs on tomb-sweeping day.
C．Various ways to care for the dead in the world.
D．Qingming Festival
2.All of the following practices are mentioned on tomb-sweeping day EXCEPT_____ .
A．Weeping over the passed-away.
B．Flying kites made from bamboo and paper
C．Sending flowers to their ancestors’ graves.
D．Burning incense and paper money for the dead.
3.Which of the following is correct according to passage?
A．Du Mu ,the well-known poet in Song Dynasty wrote a poem about Qing Ming.
B．Qingming Festival used to be a Chinese national holiday.
C．People have the custom of flying kites on Qing Ming.
D．Those whose ancestors were buried in proper places will have a bright future.
4.The writer write the passage in order to____________ .
A．enable us to observe traditional tomb-sweeping day.
B．show traditional and present ways to spend Qingming Festival .
