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, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additives,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging 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 living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical 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 control these procedures, the practices continue.
What are nitrates used for?a.They preserve flavor in packaged foods.
b.They preserve the color of meats.

Passage 2
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, at the same time, made many foods unfit to
eat. some research has shown that perhaps eighty percent of all human illness are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more prone to contract certain illness because of the food that is characteristic in these cultures.

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 control these procedures, the practices continue.
All of the following statements are true EXCEPT___.A. Forty percent of cancer is caused by problems related to food.
B. Researchers have known about the potential danger of food additives for many years.
C. We eat some of the food additives directly and some indirectly.

In ancient Egypt,as everywhere,pitching stones was a favorite children's game．But a badly thrown rock could hurt a child．Looking for something less dangerous to throw,the Egyptians made what were probably the first balls.

B.throwing stones was not fun
C.games with stones did not have rules
