Common-Cold Sense

You can’t beat it,but you don’t have to join it. Maybe it got the name"common cold"because it’s
more common in winter. The fact is,though,being cold doesn’t have anything to do with getting one.Colds
are caused by the spread of rhinoviruses（鼻病毒）,and,at least so far,medical science is better at telling
you how to avoid getting one than how to get rid of one.
Children are the most common way cold viruses are spread to adults,because they have more colds than
adults一an average of about eight per year. Why do kids seem so much more easily to get colds than their
parents?Simple.They haven’t had the opportunity to become immune to many cold viruses.
There are more than 150 different cold viruses,and you never have the same one twice.Being infected
by one makes you immune to it一but only it.
Colds are usually spread by direct contact,not sneezing or coughing. From another person’s hand to
your hand and then to your nose or eyes is the most common route.The highest concentration of cold viruses
any where is found under the thumbnails of a boy,although the viruses can survive for hours on skin or other
smooth surfaces.
Hygiene is your best defense.Wash your hands frequently,preferably with a disinfectant soap,
especially when children in your household have colds.
But even careful hygiene won’t ward off every cold.So,what works when a coughing,sneezing,runny
nose strikes?
The old prescription of two aspirins,lots of water,and bed rest is a good place to start.But you’ll also
find some of the folk remedies worth trying. Hot mixtures of sugar(or honey),lemon,and water have real
benefits.

When you are having a cold,________. A:it is always the same kind of cold that you had last time B:it may be the same kind of cold that you had last time C:it is certainly not the same kind of cold that you had last time D:it is probably not the same kind of cold that you had last time
