The cost of medical care in the US is very high．The time and money that  1  spend on their medical education is probably one reason  2  this problem．

A visit to a doctor’s office    3    from fifteen to fifty dollars．It is almost   4   for people to pay for the medical care they need．Many people in the US think that doctors  5  overpaid． Most doctors ,however,．    6   ．They say that they are required to study    7  for a long lime．Tuition(學費)for many    8  of medical education costs   9   money .Doctors say that it is necessary for most medical students to borrow money from  10   to pay their tuition．Because this money must be repaid to the bank．  11   doctors need to receive a lot of money for their work .  12   ，they charge(收費)people   13   prices for medical care．

Therefore．it is possible that the high cost of medical care in   14   is necessary，because high tuition is one cause of high costs．One way to  15  costs would be to have medical schools that are free or have low tuition．
