Ahhh...Ahhh.,..Achoo!When you do this,do you wonder how far your sneeze can travel?
　　When you catch a cold and sneeze,the virus(病毒)in it may travel at up to35meters per second.It's no surprise that the virus can go quite far,　sometimes as far as8meters.And scientists have learned that the virus can easily travel farther with wind.
　　That is to say,if you catch a cold and sneeze in the classroom,the virus in your sneeze will spread around.It may reach some students who sit beside you.However,it takes a few days for them to feel sick.At first,they don't realize their illnesses and also go to school in the next few days.As a result,they pass the virus to more students.In a classroom of50desks,this could mean10or more sick students by the end of several days..
　　So when you feel sneeze coming on,cover your mouth to prevent the spread of the virus.You can use tissues(纸巾)and then put your used into a bag.If you don't have tissues,you should sneeze into your elbow.In this way,most of the virus can be controlled in a smaller area.Next time you're not feeling good and sneeze into hands,please think about your classmates and take a sick day off.It's necessary for you to see a doctor and follow the doctor's advice.Besides,don't forget the best way to keep healthy is doing exercise..
