Statistically, air travel is by far the safest way to travel, and you can make flying even safer, just by following these simple rules. As your chances of being involved in an air accident are practically nil（零）, many of these tips concern what you should and shouldn't do to make your journey safer when you are airborne（升空的）.
● Fly on non-stop routes
Most accidents occur during the takeoff, climb, descent and landing phases of a flight, so flying non-stop reduces your exposure to these complex procedures.
● Choose larger aircraft.
Although small aircraft have very good safety records, those with more than 30 passenger seats are designed to comply（遵守）with much stricter regulations and are tested more regularly to make sure they still comply. Also, in the unlikely event of a serious accident, larger aircraft provide a better opportunity for passenger survival.
● Pay attention to the pre-flight safety briefing
The information may seem repetitious（重复的）, but it's worth listening to the flight attendants. And even if you’ve flown before, it doesn’t mean you know everything about the aircraft you're on, such as the location of the closest emergency exit.
● Store things safely
Never put very heavy articles in the overhead storage bins. They may fall out when someone opens the bin and cause injury. Also, the bin may not be able to hold heavier objects during turbulence（气流）.
● Keep our seat belt fastened while you are seated
Cabin crew always tell you this, but it’s important. You would be seriously injured if the plane hits unexpected turbulence. Always fasten your seat belt if you are told to. The general rule of flying is this: If you are told to do something, do it first and ask questions later.
● Let the flight attendant pour your hot drinks
Flight attendants are trained to handle hot drinks like coffee or tea in a crowded aisle on a moving aircraft, so allow them to pour the drink and hand it to you. Never ask to take a coffee pot from one of them.

Prevention is better than defense.4. Experts widely agree that the single best way is to get the vaccine (疫苗) each year, which is appropriate for anyone 6 months and older. 5. Moreover, practicing good hygiene can prevent flu germs from spreading. Highly recommended are washing your hands, coughing or sneezing into a tissue, avoiding touching your nose and mouth, cleaning surfaces and objects like keyboards and telephones and avoiding crowded areas.
A.Approaches to flu vary from expert to expert.
B.You can escape catching influenza with some common-sense health practices.
C.When someone with the flu coughs or sneezes, droplets carrying the virus enter the air.
D.These can include fever, achy muscles, sore throat, cough, headache, chills, fatigue or vomiting.
E.The flu shot protects against the most common three or four flu viruses research indicates that year.
F.If taken within two days, the medicine can lessen symptoms and shorten the length of time you are sick by about a day.
G.To determine if you have the flu or a cold, your doctor will do a physical exam, ask about your symptoms, and possibly do a lab test.
