Do you have a sore throat，a running nose and a headache？Do you keep coughing and sneezing？If you do，the chances are that you have a cold or perhaps flu---but which one？Although both colds and flu are caused by viruses，they are very different illnesses.
Colds，which usually last about a week，affect the nose most.They commonly cause a running nose and sneezing.Sometimes，they cause a headache，a cough and slightly aching muscles.
Flu is a much more serious illness and is caused by different groups of viruses.People with flu usually get all the symptoms（癥狀） described above.However，they also get a high fever，a dry cough and much worse aching.Fever is one of the characteristic symptoms of the flu for all ages.The symptoms also last much longer.Sometimes they don't disappear for at least two weeks.
Flu can be a deadly disease.The elderly，who are weaker and less healthy than most younger people，can die from flu.This is one reason why old people are advised to have a flu injection（預(yù)防針） before the start of winter when flu is most common.This injection is inexpensive and definitely（明顯地）worth it.
If you have a cold or flu，you must always deal with used tissues（手巾紙） carefully.Don't leave dirty tissues on your desk or on the floor.Someone else has to pick these up and viruses could be passed on.And finally，remember to cover your nose and mouth when you sneeze!You don't want to see the small drops of liquids blown（噴） out of your nose and mouth when you sneeze，do you？Disgusting（令人作嘔），eh？Now you can understand why it's a good idea to cover your nose and mouth when you sneeze!

3．What is cross country running？Cross country is an outdoor endurance（耐久性）sport that can be mentally challenging and fun.（1）
You're not only putting one foot in front of the other；you're also thinking ahead to barriers and changes in the trail or course.
（2）However，before you begin training and racing，you should be aware of potential injuries and how to avoid them.How can you prevent cross country running injuries？The best ways for outdoor runners to stay healthy include the following running tips：
Stretch daily.For all runners and athletes，a regular stretching routine is an important part of conditioning.（3）
Warm up and cool down.Muscles and tendons（跟腱）are less likely to overstretch or tear if they've been properly prepared for running and racing.High-intensity workouts require more prep and post-workout cool down than low-impact activities.
Wear the right shoes.Make sure your shoes fit properly and that they are neither too tight-fitting nor too loose.（4）
Eat and drink enough.Competitive distance runners like to keep their weight low.However，consuming too few calories can harm your body，especially if you're a girl or woman subject to eating disorders.（5）It's effective to prevent injury and heat illness.Remember that especially in full sun or in humid regions of the state，you particularly tend to have heat stroke.Drink plenty of water before and after running.
A.Cross country running is a sport requiring money.
B.Tie double-knots to prevent tripping over undone laces.
C.It's mostly very safe in comparison to other team sports.
D.Have a well-balanced diet and be sure to stay well-hydrated.
E.You may encounter unexpected，non-natural barriers.
F.It is needed to keep your bones，joints，and muscles healthy.
