13.A food additive is any substance that is added to food.Many people are put off by the idea of"chemicals in food".The truth is that all food is made up of chemicals.Natural substances like milk,as well as man-made ones like drinks on sale in the market,can be described by chemical formulas.Some chemical substances are indeed harmful,but a person who refused to consume any chemicals would find nothing to eat.The things we eat can be divided into natural and man-made substances.Some people feel that only natural foods are healthy and that all man-made ingredients are to be avoided.But many natural chemicals,found in plants and animals,are harmful when eaten,and some laboratory-made substances increase the nutritional value of food.Other chemicals have natural and man-made forms that are exactly alike:Vitamin C is Vitamin C,whether it comes from a test tube or from an orange.Like"chemical","man-made"doesn't necessarily mean"not fit to eat".?
Food additives are used for many reasons.We add sugar and salt and other things to foods we prepare at home to make them taste better.Food producers have developed a range of additives that stabilize,thicken,harden,keep dry,keep wet,keep firm,or improve the appearance of their products.Additives can make food more convenient or nutritious,give it a longer shelf life,and make it more attractive to the consumer,thus increasing the sales and profits of the producers.?
Food additives are presently the centre of a storm of serious argument.Food producers have been known to use additives that have not been proved safe; some substances in common use have been proved unsafe and have been taken off the market.Many people feel there's a risk of eating food to which anything has been added.But food additives are now regulated by the FDA of the federal government,and new additives are subjected to strict testing before they can be placed on the market.For most people,the chances of developing serious side effects from the long-term use of presently approved food additives are very slim.?

分析 本文介绍了食物添加剂的种类作用,人们对食物添加剂的担忧以及联邦政府为保证食物添加剂的安全所做的努力.
解答 32.A.细节理解题.根据第一段第三句The truth is that all food is made up of chemicals.和最后一句Some chemical substances are indeed harmful,but a person who refused to consume any chemicals would find nothing to eat.可知现在所有事物都含有添加剂,如果一个人拒绝食用任何形式的添加剂,他会发现自己没有东西吃.也就是说所有食物都有化学添加剂的成分.故A正确.
33.D.细节理解题.根据第三段Additives can make food more convenient or nutritious,give it a longer shelf life,and make it more attractive to the consumer,thus increasing the sales and profits of the producers.可知添加剂让食物的味道更好,可以提高产品的外形,更吸引消费者,更方便更有营养.说明添加剂可以在很多方面提高食物的品质.故D正确.
34.D.推理判断题.根据文章最后两句For most people,the chances of developing serious side effects (副作用) from the long-term use ofpresently approved (批准) food additives are very small.说明食物添加剂受到联邦政府的严格控制并经过严格的测试,对人的副作用会很小.故D项正确.
35.B.推理判断题.根据文章最后一段前两句可知人们对食品添加剂有很多担心,但是根据最后两句But food additives are now regulated by the FDA…food additives are very small.可知食物添加剂受到联邦政府的严格控制并经过严格的测试,对人的副作用会很小.也就是说作者认为食物添加剂还是可以接受的.故B正确.
