Passage 2

Questions 6 to 10 are based on the following passage:

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 tat 40 percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures ate more prone to get certain illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates and nitrites, 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 that 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 control these procedures, the practices continue.

What makes a child speak a language has long been a puzzle to linguists. 61 speaking, there are two schools of linguists, both of whom try to explain 62 a child picks up a language so easily. The fact that a child picks a language 63 is 64 : At one year old, a child is able to say “bye-bye”; at two, he is able to use fifty; by there he begins to 65 tenses. The famous American linguist Noam Chomsky 66 that human being have a sort of built-in system for language use, and that the 67 is 68 . Children are not taught language 69 they are taught arithmetic. Other linguists, 70 , hold the view that a child learns 71 of his language from the hints in the environment. 72 , theorists of both schools 73 that there is a biological basis for language use. The 74 is which is more important, the inner ability or the environment. This is certainly a field 75 to be explored. Researchers from both schools are busy finding evidence to 76 their own theory, but 77 side is persuading the other.

It seems that in order to 78 why a child learns a language so easily, we have to 79 the joint efforts of both schools. Some linguist, like De Villiers, has recognized the value of cooperation, and 80 linguists of both sides to work together.
