21、】 Section B 36 How to Duck Cabin Fevers and Other Aches on a Plane? A On the first leg of this seasons holiday travel tour, I had the delightful experience of watching my 20-month-old touch nearly every surface on our airplane, from numerous armrests and people we passed in the aisle to our fingerpr

22、int-stained window. As a somewhat uncontrollable germaphobe (洁癖 ), it took everything I had not to dip my son in hand sanitizer (消毒剂 ) and then physically restrain him. But I was flying alone with two children and he was happy eating those snacks off the floor, and so, for the sake of my fellow pass

23、engers, I let him handle pretty much anything he wanted. Hence, I wasnt surprised when his nose started running shortly after we arrived at our destination, followed by the inevitable cough, which his older brother also picked up. Our “vacation“ ended at a CVS Minute Clinic, with ear infections for

24、both kids. B Coming down with a cold, cough or other illness after air travel is a common refrain, even from adults who dont try to lick the seatback tray table. But is the plane really to blame? Not particularly, says aviation medicine specialist Mark Gendreau, vice chair of emergency medicine at t

25、he Lahey Clinic in Burlington, Mass. “You do have a higher risk of contracting a viral infection while traveling, but you have to remember that its really the door-to-door experience thats exposing you to germs: the crowds on the subway to the airport, the escalator, the security line, getting on an

26、d off the aircraft,“ he explains. “Its almost impossible to say where, exactly, you get sick.“ C In fact, experts point out that the environment of a plane is probably less risky, health-wise, than many other crowded, confined spaces. Given airliners improved ventilation systems, germs arent being c

27、onstantly circulated through the plane, stresses Gendreau. Instead, he says, you are most likely to pick up a bug from close contact with a sick person or by touching a surface thats been coughed or sneezed on or otherwise contaminated, such as an armrest or an overhead bin lock. D Studies have show

28、n that the highest risk of germ transmission on a plane, by far, comes from those around you, particularly those seated within two rows, says Michael Zimririg, director of the Center for Healthy Travel at the Mercy Medical Center in Baltimore. “The closer the proximity and the longer the time youre

29、confined with someone in a closed compartment and usually its at least a couple of hours the better the chance of catching a cold,“ he says. E Research published last May in the journal BMJ studied a packed, long-haul 747 flight from Los Angeles to New Zealand that had at least nine passengers who w

30、ere later confirmed to have swine flu. Researchers found that the three additional travelers who appeared to have contracted the virus on the flight were all sitting within two rows of an infected person; that put the chance of transmission at 3.5 percent within two rows and roughly 1.9 percent for

31、anyone in the same section of the plane. F “Theres no doubt that planes are pretty germy,“ says Charles Gerba, a professor of microbiology at the University of Arizona who studies how diseases are transmitted in indoor environments. “There is no requirement or regulation for the cleaning and disinfe

32、ction of airplanes its up to individual airlines and it just doesnt get done regularly,“ he said. The dirtiest spot on board? By far, the restrooms, according to Gerba, who says that in the course of his research, he has identified E. coli bacteria on almost every toilet surface, with the worst offe

33、nders being sink handles and faucets, soap dispensers and door handles. G Of course, just because such germs are there doesnt mean theyre a problem. “There is definitely an unpleasant factor, but its one thing to say theres a virus or bacteria on a surface, and another thing for that to make you sic

34、k,“ says Katherine Andms, assistant general counsel for the Air Transport Association, a trade group representing major U.S. airlines. “Most of us, if were relatively healthy and have good immune systems, dont have to worry that much about all of the surfaces in the world that may be contaminated.“

35、She adds that frequent, proper hand washing goes a long way toward preventing illness in any crowded environment. H There are several other steps you can take. Zimring, author of “Healthy Travel: Dont Travel Without It,“ says its important get enough sleep, eat healthfully, exercise and get a flu sh

36、ot to build up immunity before traveling. Gendreau suggests the following to stay healthy while flying: I Drink up. Proper hydration (水合作用 ) is critical to optimal immune function. Given that the relative humidity in a passenger cabin can be as low as 10 percent on long flights, its essential to dri

37、nk as much water while in the air as possible; avoiding alcohol will help, too. Staying well hydrated can also help prevent mild altitude sickness, with symptoms such as headache, lightheadedness and nausea (恶心 ) which people often mistake for a post-flight cold or flu. J Pack a hand sanitizer. Soap

38、 and water do a great job, but the restrooms sink handle, soap dispenser and doorknobs may be contaminated with germs. So use alcohol-based sanitizer after leaving the restroom and throughout the rest of your flight. And think twice before you rub, scratch or otherwise pat your face during a flight;

39、 those simple acts can provide ample opportunity for the transmission of bacteria and viruses. K Be wary about that tray. Air carriers with flight turnover times of less than an hour do not routinely disinfect the trays or other surfaces such as the armrests and windows. So wipe them down with an al

40、cohol-based sanitizer when you first take your seat. L Keep the air turned on at your seat. When people cough, sneeze or speak, they eject up to 30,000 droplets, which can travel several feet. To minimize the chance of infected droplets landing on you, turn your air vent to medium flow and position

41、it so that the air current is directed just slightly in front of your face. That will help direct germs away from your eyes, nose and mouth. M As for me, I think I will run with my germaphobic tendencies from now on, forbidding floor snacks, using a great amount of sanitizer on both my children and

42、wiping down our immediate surroundings as soon as we board. The travel might not be happier for me or for my fellow passengers but if its even slightly more healthful, I think its worth it. 37 It is pointed out that the infection possibility is closely related to the distance and the time spent with

43、 others in a closed compartment. 38 An aviation medicine specialist believes its impossible to identify where a passenger get infected. 39 Because of my fellow passengers, I let my little son deal with anything he desired, even though I usually do not. 40 During flying, drinking enough water is of m

44、uch significance for immune function to be in its best state. 41 As it is not obligatory for airlines to clean the planes, planes undoubtedly abound with germs. 42 A study stated that the chance of transmission within two rows was 1.6 percent higher than in the same section of the plane. 43 It would

45、 be better not to tap your face during a flight because it might help bacteria to transmit. 44 The existence of germs doesnt necessarily mean that they will make you sick. 45 According to a university professor, restrooms are the dirtiest place on planes. 46 Its suggested that you use sanitizer to c

46、lean the armrests and windows the first time you take the seat. Section C 46 The poor old consumer! Wed have to pay a great deal more if advertising didnt create mass markets for products. It is precisely because of the heavy advertising that consumer goods are so cheap. But we get the wrong idea if

47、 we think the only purpose of advertising is to sell goods. Another equally important function is to inform. A great deal of the knowledge we have about household goods derives largely from the advertisements we read. Advertisements introduce us to new products or remind us of the existence of ones

48、we already know about. Supposing you wanted to buy a washing machine, it is more than likely you would obtain details regarding performance, price, etc., from an advertisement. Lots of people pretend that they never read advertisements, but this claim may be seriously doubted. It is hardly possible

49、not to read advertisements these days. And what fun they often are, too! Just think what a railway station or a newspaper would be like without advertisements. Would you enjoy gazing at a blank wall or reading railway bylaws while waiting for a train? Would you like to read only closely-printed columns of news in your daily paper? A cheerful, witty advertisement makes such a difference to a dull wall or a newspaper full of the daily ration of calamities. We must not forg
