问题     Are organically grown foods the best food choices?The advantages claimed for such foods over【C1】______grown and marketed food products are now being debated.【C2】______of organic foods-a term whose meaning varies greatly-frequently proclaim that【C3】______products are safer and more nutritious than others．
    The growing interest of【C4】______in the safety and nutritional quality of the typical North American diet is a welcome development.【C5】______，much of this interest has been sparked by sweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs.Although most of these【C6】______are not supported by scientific evidence，the preponderance(优势)of written material【C7】______such claims makes it difficult for the general public to separate fact from【C8】______．As a result，claims that eating a diet【C9】______entirely of organically grown foods prevents or【C10】______disease or provides other benefits to health have become widely【C11】______and form the basis for folklore．Almost daily the public is【C12】______by claims for“no-aging”diets，new vitamins and other【C13】______foods．There are numerous unsubstantiated reports that【C14】______vitamins are superior to synthetic ones，that fertilized eggs are nutritionally【C15】______than unfertilized eggs and the【C16】______．
    One thing that most organically grown food products seem to have in common is that they【C17】______more than conventionally grown foods．But in many cases consumers are【C18】______if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods．So there is real cause for concern if consumers particularly those with【C19】______incomes，distrust the【C20】______food supply and buy only expensive organic foods instead．
【C18】
选项 A、misled
B、mislaid
C、overcharged
D、mispriced
答案A
解析 语义衔接题。所填词的逻辑宾语是consumers“消费者”，四个选项中能以人作宾语只有选项A) misled，即mislead“误导”。选项B) mislaid，即mislay“放错”；选项C) overcharged“索价过高”；选项D) mispriced“给……定错价格”。本句大意是: 如果消费者认为有机食品能预防疾病且营养价值高于以常规方式生产的食品，那么他们就被误导了。所以答案是A) 。
