距离2017年6月大学英语四级考试还有不到一个半月的时间，已经报名的同学备考一定要抓紧，不要临时抱佛脚。新东方网英语四级频道为大家整理了英语四级阅读理解单项训练习题，每天一道题考试不担心。
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
additivies,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.
