     Unlike Britain, the US does not have a national health care service. Most people buy medical

insurance to help pay for medical care. The government  only helps pay for some medical care for

the old and the people who are on low incomes. The problems of those who cannot afford insurance

have become an important political subject.

     In Britain, when people are ill, they usually go to a family doctor first. However, people in

America sometimes go straight to an expert. Children are usually taken to a doctor who is an expert

in the treatment of children. In Britain, if a patient needs to see a specialist doctor, their family doctor

will usually recommend a specialist,  which will save more time and money both for the patients  and

the public fund (基金).

     In Britain, doctors  do not go to people's homes when they are ill. People always make

appointments to see the doctor in the doctor's office. In a serious situation, people call for an

ambulance. In America, hospitals must treat all seriously ill patients, even if they do not have medical

insurance. The government will then help pay for some of the cost of the medical care.
