The common cold is the world's most widespread illness, which is plagues (瘟疫) that flesh receives. The most widespread fallacy (谬误) of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one.
If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.
　　During the First World War soldiers who spent long periods in the trenches (战壕) cold and wet, showed no increased tendency to catch colds. In the Second World War prisoners at the notorious Auschwitz concentration camp (奥斯维辛集中营), naked and starving, were astonished to find that they seldom had colds.
　　At the Common Cold Research Unit in England, volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be dipped with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
　　If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.
　　No one has yet found a cure for the cold. There are drugs and pain-killer pills such as aspirin, but all they do is relieve the symptoms.

　　If you are ever lucky to be invited to a formal dinner party in Paris, remember that the French have their own way of doing things, and that even your finest manners may not be “correct” by French custom. For example, if you think showing up promptly at the time given on the invitation, armed with gifts of wine and roses, complimenting your hostess on her cooking, laughing heartily at the host's jokes and then leaping up to help the hostess will make you the perfect guest, think again.

　　Here Madame Nora Chabal, the marketing director of the Ritz Hotel in paris, explained how it works.

　　The first duty of the guest is to respond to the invitation within 48 hours. And, the guest may not ask to bring a guest because the hostess has chosen her own.

　　Flowers sent in advance are the preferred gift. They may also be sent afterwards with a thank-you note. It is considered a very bad form to arrive with s gift of flowers in hand there by forcing the hostess to deal with finding a vase when she is too busy to do that. See, that's the logic! The type of flowers sent has a code of its own, too. One must never send chrysanthemums because they are considered too humble a flower for occasion. Carnations are considered bad luck, and calla lilies are too reminiscent（令人联想）of funerals（葬礼）. A bouquet of red roses is a declaration of romantic intent. Don't send those unless you mean it, and never to a married hostess. And though the French love wine, you must never bring a bottle to a dinner party. Why, it's as if you feared your hosts would not have enough wine on land, and that's an insult. You may, however, offer a box of chocolates which the hostess will pass after dinner with coffee.

　　If an invitation is for eight o'clock, the considerate guest arrives at 8:15. Guests who arrive exactly on time or early are mere thoughtless ones who are not giving the hostess those last few minutes she needs to deal with details and

crises, The “correct” guest arrives between 15 to 20 minutes after the hour because dinner will be served exactly 30 minutes past the time on the invitation.
