题目内容
18.The food we eat seems to have profound effects on our health.Although science has made big 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 80percent of all human illness are connected with diet and 40percent of cancer is connected with the diet as well.That food is connected with illness is not a new discovery.In the 1940s scientists realized that nitrates(硝酸盐),which are often used to keep color of meat,and other additives(添加剂)caused cancer.However these additives remain in our food and it becomes more difficult to know which additives are helpful or harmful.Farmers sometimes give drugs to animals not because the animals are ill but because they want to sell the animals at higher prices.For example farmers try hard to make animals grow big so that they can sell the big animals for more money.Although the Food and Drug Administration has tried again and again to control farmers to do so,farmers go on doing this.44.According to the passage,what has science done to mankind?C
