In the past, operations were difficult. Until the middle of the eighteen
fifties, surgery was very dangerous. Many patients died after even the smallest
operations. This was because bacteria entered the cuts in the patients
bodied’and started infection. In some countries, up to 90 percent of patients
died from inf ection after operations. In 1865, however, Joseph Lister, a
British surgeon, found an answer to the problem. He used an “antiseptic during”
and after operations. This killed the dangerous bacteria and most of his
patients lived. Since then, surgeons have used antiseptics in all
operations.Surgery has developed in many important ways since the day of Joseph
Lister. Today, when patients go to hospital for an operation, they can expect

Passage 4

Culture shock is caused by the anxiety that results from losing all familiar
signs and symbols of social intercourse. Those signs are as following: when to
shake hands and what to say when meet people, when and how to give tips, how to
make purchases, when to accept and refuse invitations, when to take statements
seriously and when not. These signs, which may be words, gestures, facial
expressions, or customs, are acquired by all of us in the course of growing up
and as much a part of our culture as the language we speak or the beliefs we
accept. All of us depend on hundreds of these signs for our peace of mind and
day-to-day efficiency, but we do not carry most at the level of conscious
awareness.
Now when an individual enters a strange culture, all or most of these
familiar signs are removed. No matter how broadminded or full of good will you
may be a series of supports have been knocked from under you, followed by a
feeling of frustration. When suffering from culture shock people first reject

The food we eat seems to have profound effects on our health. Although
science has made enormous steps in making food more fit to eat, it has , atthe
same time, made many foods unfit to eat. Some research has shown that perhaps
eighty percent of cancer is related to the diet as well, especially cancer the
colon . Different cultures are more prone to contract certain illnesses because
of the food that is characteristic in these cultures. That food related to
llness is not a new discovery. In 1945 , government researchers realized that
itrates and nitrites, commonly used to preserve color in meats, and other food
dditives, caused cancer. Yet, these carcinogenic additives remain in our food,
nd it becomes more difficult all the time to know which things on the pack ging
labels of processed food are helpful or harmful.The additives which we eat are
not all so direct. Farmers often give penicillin to beef and poultry, and
because of this, penicillin has been found in the milk of treated cows.
Sometimes similar drugs are administered to animals not for medicinal purposes,
but for financial reasons. The farmers are simply trying to fatten the animals
in order to obtain a higher price on the market. Although the Food and Drug
Administration (FDA) has tried repeatedly to controlthese procedures, the
practices continue.
