In each country there is  a system of health care and russia is 

not an exception. I want to tell about medical care in my country.  In Russia health 

care is free. The basic medical unit in our country is a polyclinic. We 

have polyclinics for adult population and for children population . A patient who

is ill can call and invite a doctor  for a  home visit in a case of 

emergency. The emergency ambulance service operates all day and all night and is 

free of charge. There are many hospitals in Russia for different 

diseases. The ambulances  are equipped with a  modern equipment. I think that  the system of health care in Russia is very good.( лучше сказать quite good, a very good как-то не очень звучит)
