As we all face the novel coronavirus （新冠病毒） ，protecting yourself is the same as protecting others.Here are some suggestions.
    Stay away from the crowded places and wear masks （口罩）.
    如果你不得不去擁擠的地方，記得戴口罩。Keep at least one metre between yourself and other people，especially those who are coughing or sneezing.
    Why？The droplets （粘液飛沫） can be transmitted （傳播） farther by sneezing or coughing than by speaking.If you are too close，you can breathe in the virus （病毒）.Wearing a mask can stop droplets from reaching your face or mouth.
    Keep proper indoor ventilation （通風(fēng)）.
    Keep proper indoor ventilation while at home.Open windows to let in fresh air during the day.It's best to do this three times a day.
    Why？The virus can only infect （感染） you when it builds up to a certain amount.Proper ventilation can stop the virus from gathering into a large amount.
    Keep up good habits.
    Keep healthy habits such as eating healthily，exercising regularly，and getting enough sleep.
    Why？Doing these things can strengthen your immune system （免疫系統(tǒng)）.It is not easy for you to become infected.
    Wash hands properly.
    Remember to wash your hands before eating，after going to the bathroom，coming home，coming into contact with rubbish and touching animals.Avoid touching your eyes，nose and mouth before washing your hands.
    Why？Your hands might touch surfaces with the virus. Washing your hands in time can stop the virus from entering your body
