The National Health Service in Britain was set up in 1948 (26) shortly after the end of the Second World War. Its (27) aim is to provide free medical treatment for all patients who wish to take advantage of the (28) service. However, it is still possible to (29) obtain private medical treatment and in this case the doctor charges a fee.
  To say that the National Health Service is free is not (30) entirely true. Every employed or self- employed person over 16 years of age must put a stamp on an (31) insurance card every week. This card is (32) issued by a government department called the Department of Health and Social Security. The stamp costs money and the (33) amount is constantly changing. (34) Part of the cost of this stamp, in fact. the greater part, is borne by the employer, and it finances the National Health Service together with many other social security benefits such as retirement pensions, unemployment benefit, sickness benefit and so on.
  In order to participate in the Health Service, a patient must register with a General Practitioner, usually known as a G.P. (35) Whenever he is iii or needs to consult a doctor for any reason he will in every case go to see his G.P. If the doctor feels that the case needs more expert help or the use of greater resources than are at his disposal, (36) he will give his patient a letter to take to a hospital where more advanced treatment is available.
