It's 10:00 on a beautiful Sunday morning in California. To my left is some of the most beautiful coastline. I'm walking along a road ordinarily packed with cars on days like this, but today, thanks in part to my $135 entry fee, it is closed to traffic.

    There's only one problem: I should be running, not walking. Over the past year, I've spent hundreds of dollars on running gear(设备) and race entry fees. I've jogged than 1,600 miles training for this event.

    Dozens of runners pass me on either side, each of them experiencing varying degrees of sadness similar to my own. Most of them, like me, have traveled hundreds of thousands of miles to get here, spending $500, $1,000 or more to participate in this event.

    Actually I'm by no means a competitive athlete. My best finish ever was fourth place, in a 5-kftometer race with only 74 participants, many of whom were walking the entire course.

    Last year, over 500,000 runners completed a marathon in the U.S. alone. Nearly all of these runners had absolutely no chance of victory. The PR-personal record-is everyone's definition of a “good race,” whether he finishes in first or 301st.

    I should buy a new watch that not only tracks my location by GPS, but also by counting steps. This can more accurate and much more expensive. Finally, I have reached the finish line. I know that the official race photographers will be taking photos as I cross the line, so I raise my arms in “victory” I finish, in a time of 3:37:55, good for 354th place.

    A few days after the race, the race organizers email me a link to a site where I can preview my official photos 一 and download them, for a fee, of course.

    I wish I could say the feeling was unique; it's probably not Indeed probably a feeling most runners get in most marathons. Running a lot of marathons 9 in fact, may not even be good for your health.

    In America, marathoning is a rich person's sport.

    For most of us Veterans Day just means a chance to enjoy an extra day off from school or work．However this November 11th，be sure to spend a few minutes on its true purpose，by acknowledging（感谢）the men and women who have served in our armed forces．

    And you don't have to stop at just this one day．Join the over 10，000youth members of the Young Marines group that honor these brave men and women all year long with special events and completely spoil them for an entire week，from November 4th to 11th，by visiting hospitalized veterans，performing chores for disabled veterans and even organizing community－wide social event．The program open to kids ranging from the age of eight all the way to high school，is a great way to not only show your appreciation，but also get a chance to do some fun activities with like－minded kids and make a real difference in a veteran's life．

    People often believe that Memorial Day and Veterans Day are celebrated for the same reason．There is however a subtle but important difference between the two．While both honor our military personnel，the former is a day to remember and pay respect to all the men and women that died serving our country in a war，while Veterans Day is to celebrate the soldiers who are still alive and served in the forces at any time，during peace or war． Though several other countries celebrate this day in honor of their own veterans，the meaning is slightly different for each one．Some like the United Kingdom，celebrate it in honor of all soldiers－living or dead，while others like Canada celebrate it to honor all living veterans．They also call it different names．France and New Zealand sill call it Armistice Day．In the United Kingdom，Australia and Canada it is referred to as Remembrance Day，while Malta and South Africa celebrate it as Poppy Day．

    No matter what it is called，the reason for observing the day is the same－to show our appreciation to the brave men and women who sacrifice（牺牲）everything to make this world a safer place for the rest of us．

    At no time in history has there been such a mass movement of people from the countryside to the city as is happening now. By the year 2030, it's estimated that more than two thirds of the world's population will be living in cities, twice as many as today. This means that the problems faced by cities today-overcrowding, poor housing, unemployment, poverty and lack of food and water—will be twice as bad, unless we find solutions soon.

    Another serious issue is how to provide good transportation for their citizens. Many of the world's major cities are already struggling with out-of-date transport infrastructures (基本设施). How can they deal with the additional demands?

    London is a good example. Its enlargement was made possible by the invention of the steam engine, which powered the world's first underground railway. But its transport system are now hopelessly out-of-date and need urgent modernization. London's future success depends very much on developing better public transport

    Over a million people travel into central London every day from outside the city. They, together with the people who live in London, want a public transport system that is efficient, safe and environmentally friendly. What they often get, however, falls far short of that ideal. Passengers complain about cost and pollution, while businesses worry about the problems their staff have in getting to work on time. Yes, the proportion of London households that own a car grew from just over ten percent in the early 1950s to over sixty percent today.

    As the city has become increasingly crowded and polluted, there has been a growing realization that action must be taken soon.

    Everyone should be so lucky as to have a friend like Francia Raisa. On Thursday, singer and actress Selena Gomez, 25, used Instagram to explain why she was “laying low” this summer. She posted a photo of herself in a hospital bed with her friend Francia Raisa holding hands. She said she recently received a kidney transplant from her best friend because of complications（并发症）from lupus（狼疮）, an autoimmune disease, which means it is the result of the immune system attacking normal tissue, including the kidneys, brain, heart and lungs.

    People with lupus may first experience tiredness, joint pain or a little bit of rash（皮疹）on their bodies and can go for a long time before their doctors realize it is more serious. Many people see two or four doctors before the real problem is picked up. According to Dr. Kyriakos Kirou, roughly a third to one-half of people with lupus develop kidney disease, and up to one in five of them will eventually need a transplant, sometimes because they weren't treated with effective drugs to prevent the immune system from attacking the kidneys. Though Gomez said that she was “very well now,” she warned about the dangers of not taking medical diagnoses seriously, like she initially did.

    Her Instagram post also called attention to two major health topics: the need for living organ donators and the fact that Gomez represents three groups more likely to be diagnosed with lupus and lupus-related kidney disease. Nine out of 10 people diagnosed with lupus are women, and most develop the disease between the ages of 15 to 44. And lupus is two to three times more common among women of color, including Hispanic women, according to the Lupus Foundation.

    Raisa is Latina, and Gomez's father is of Mexican origin. While it's not essential that the organ donator and receiver be of the sane ethnicity, people who share a similar background sometimes are better matched, according to data from the United Network for Organ Sharing.
