(2017·开封高三模拟)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 crash are practically nil (零), many of these rules concern what you should and shouldn't do to make your journey safer when you are in the air.

　　●Fly on non­stop routes

　　Most air crashes occur during the take­off, climb, descent and landing period of a flight, so a non­stop flight reduces your exposure to these complicated procedures.

　　●Choose larger aircrafts

　　Although small aircrafts have very good safety records, those with more than 30 passenger seats are designed to comply with much stricter regulations and are tested more regularly to make sure they still comply. Also, in the unlikely event of a serious crash, larger aircrafts provide a better opportunity of passenger survival.

　　●Pay attention to the pre­flight safety briefing (简报)

　　The information may seem to be repeated, but it's worth listening to the flight attendants. And even if you have 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 bin. They may fall out when someone opens the bin and cause injury. Also, the bin may not be able to hold heavy objects during the violent movements of air caused by the wind.
