    Most people who fly on passenger planes in the United States do not lose their luggage. Even if the luggage is lost, usually it is only delayed. Most “lost” luggage is found in a few days. Airlines search for the owners of unclaimed(未认领的) bags for up to three months. But when the owners cannot be found or the bags are not claimed, they are sold to a store in the small city of Scottsboro, in the southern state of Alabama.

    About one-half of one percent of all luggage passing through US airports is unclaimed. Many of the missing bags, and what is in them, are sold at the Unclaimed Baggage Center. Seven thousand items arrive at the store every day. Tom Barnes, who was shopping at the store said, “I can go into any of the large shopping centers, like the international malls. I can walk through there for an hour and come out with three items. But I come into this store, and then I come out with my car full of stuff.”

    Brenda Cantrell, who works at the store, said, “The Unclaimed Baggage Center is the only store in America that buys and resells unclaimed baggage from the airline industry. You would be surprised at all the jackets, eyeglasses, neck pillows, blankets, laptops, Kindles, iPads, and you know, all kinds of expensive electronics.”

    The store says it once sold a container for flowers for $80 that was found to be worth $18,000. And it says a painting it sold for $25 was later found to be worth $25,000.

    The store buys the luggage from the airlines. It does not examine the things inside them before buying them. Only about half of the items in the bags are suitable for sale at the store.

    Some people say it is not fair to the owners of the lost passage to sell their goods. Customer Daniel Martin is not one of them, saying, “I feel the airport may try to find the people that lose the things. If they've tried and they can't get a hold of them, it's better than throwing them away or just letting them rot in a warehouse somewhere.”

    This story happened when I was in Saint Lucia with my family. My sister, Diana, who also happens to be my best friend and one of the funniest and kindest people I know, went blind in one eye about 9 years ago. Diana sometimes feels concerned about the way her eye looks now. The pupil(瞳孔) is no longer black; it's sort of "glows" in photos. Diana recently purchased a special contact lens (隐形镜片) that makes her eye look like it did before it changed color, but she doesn't wear this lens often because it becomes quite painful after about an hour.

    One night during our holiday, a hotel photographer was taking pictures of the guests as they entered the area set up for dinner. Diana casually said if she had known there was going to be pictures taken to capture this special memory, she would have worn her contact lens so her eye wouldn't be so shiny in the picture.

    The next day, I was sitting with Diana and her husband Ted. While we were talking, the photographer who had been at the dinner the night before, handed her a photo, leaned in and quietly said, "I matched the color of your eyes in the picture."

    As he walked away, my sister happily said to me and Ted, "Look! He fixed my eye!" The photographer stopped. He turned around and walked back to our table. He put his hand on Diana's shoulder, leaned in again and gently said, "Just to be clear: I didn't fix your eye. There isn't anything wrong with your eye. I simply matched the color. "

    Her eyes filled up with tears. It was very healing for her heart to hear these beautiful words. It didn't take much time and made so much difference. It helped her change the way she feels about herself.

    I have always loved the quote: "The world is full of good people. If you can't find one, be one!" Your acts of kindness can impact the world in profound ways!

    There are two types of people in the world. Although they have equal degree of health and wealth and other comforts of life, one becomes happy, the other becomes unhappy. This arises from the different ways in which they consider things, persons, events and the resulting effects upon their minds.

    People who are to be happy fix their attention on the convenience of things. The pleasant parts of conversation, the well prepared dishes, the goodness of the wine, the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the opposite things. Therefore, they are continually dissatisfied. By their remarks, they sour the pleasure of society, offend (hurt) many people, and make themselves disagreeable everywhere. If this turn of mind was founded in nature, such unhappy persons would be the more to be pitied. The intention of criticizing and being disliked is perhaps taken up by imitation. It grows into a habit, unknown to its possessors. The habit may be strong, but it may be cured when those who have it realize its bad effects on their interests and tastes. I hope this little warning may be of service to them, and help them change this habit.

    Although in fact it is chiefly an act of the imagination, it has serious results in life since it brings on deep sorrow and bad luck. Those people offend many others; nobody loves them, and no one treats them with more than the most common politeness and respect. This frequently puts them in bad temper and draws them into arguments. If they aim at getting some advantages in social position or fortune, nobody wishes them success. Nor will anyone start a step or speak a word to favor their hopes. If they bring on themselves public objections, no one will defend or excuse them, and many will join to criticize their wrongdoings. They should change this bad habit and be pleased with what is pleasing, without worrying needlessly about themselves and others. If they do not, it will be good for others to avoid any contact with them. Otherwise, it can be disagreeable and sometimes very inconvenient, especially when one becomes mixed up in their quarrels.

    Companion planting is the idea that some kinds of plants can help each other grow. Plants that are compatible (兼容的，能共处的) together generally have similar needs in terms of nutrients, soil and moisture levels.

    Advice about which plants are compatible is sometimes based more on tradition than proof. But experts say there is evidence to support certain combinations. These can improve harvests, reduce disease and help with pest control by attracting helpful insects.

    For example, some kinds of soil bacteria take nitrogen from the air and make it into a form that plants can use. The plants hold the nitrogen in their roots. Legumes (豆科植物) are especially good at this nitrogen (氮) fixing. Then any crops that share the same space with the legumes can get the nitrogen when the roots are broken down.

    Beans and potatoes can also share territory well because their roots reach different levels in the soil. Deep-rooted vegetables get nutrients and moisture from lower down in the soil, so they do not complete with plants with shallower roots.

    But some plants placed together may harm each other's development. For example, tomatoes do not like wet soil but watercress does, so you would probably want to keep them separated.

    Some kinds of produce should be kept apart even after being harvested. This is because of ethylene gas (乙烯气体). Ethylene is a plant hormone (激素) that can cause some foods to ripen too quickly. Apples release ethylene gas. Apricots, melons and tomatoes also release a lot of ethylene. Some vegetables are easily affected by ethylene, including asparagus, broccoli, cabbage and cucumbers.

    This risk of ripening too soon is why markets often separate high ethylene-producing foods from those that are sensitive to the gas. But if you put an apple in a bag with a green banana, the ethylene from the apple will make the banana ready to eat sooner.

    What about peaches, plums and nectarines? These kinds of fruit do not need any help from an apple—they release enough ethylene to ripen themselves. But that does not mean there is no way to get the job done faster.

    Growers suggest placing the fruit in a fruit bowl or in a paper bag with the top folded over. Keep the fruit at room temperature, out of direct sunlight. Once the fruit is soft enough, either use it or put it in the refrigerator to keep it from getting too ripe.

    The Winter Olympics is also called the White Olympics. At this time, many colorful stamps are published to mark the great Games. The first stamps marking the opening came out on January 25, 1932 in the United States for the 3rd White Olympics. From then on, publishing stamps during the White Olympics became a rule.

    During the 4th Winter Olympic Games a group of stamps were published in Germany in November 1936. The five rings of Olympics were drawn on the front of the sportswear. It was the first time that the rings appeared on the stamps of the White Olympics.

    In the 1950's, the stamps of this kind became more colorful. When the White Olympics came, the host countries (东道国) as well as the non-host countries published stamps to mark those games.

    China also published four stamps in February 1980, when the Chinese sports men began to take part in the White Olympics. Japan is the only Asian country that has ever held the White Olympics. Altogether 14, 500 million stamps were sold to raise money for this sports meet. Different kinds of sports were drawn on these small stamps. People can enjoy the beauty of the wonderful movements of some sportsmen.
