Sneezing(打喷嚏) is one way the body
protects itself from {#blank#}1{#/blank#} (sick). Your brain {#blank#}2{#/blank#}(signal) you to sneeze. Then your eyes close
and-achoo!-germs (细菌) {#blank#}3{#/blank#}(shoot) out of your nose.
One sneeze can put as many as 40,000 droplets of saliva
(唾液) and mucus (黏液) into the air. And those droplets
travel up to 100 miles per hour, {#blank#}4{#/blank#}(fast) than cars on the freeway.
Here in the US, we say "bless
you" when someone sneezes. The same goes for
a number of other {#blank#}5{#/blank#}(country), including Wales and
France. But {#blank#}6{#/blank#} general
it's more common {#blank#}7{#/blank#} (connect) to health than to
give blessings. In China, you say, "May you live
100 years!" In Germany, it's simply, "Health!"
{#blank#}8{#/blank#} do we wish sneezers well? The custom may date
back to {#blank#}9{#/blank#}ancient belief. It is said that evil
(邪恶的) spirits went out of
our bodies during a sneeze - and that these spirits then try to get back in.
Your nose can produce up to 32 ounces of mucus
every day. That's enough mucus
to fill more than two soda cans.
Mucus is {#blank#}10{#/blank#} (usual) clear. If it's green, yellow, or brown, then you might want
to see a doctor.
