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. [br] 【C7】
选项 A、proposing
B、prompting
C、suggesting
D、advancing
答案 D
解析 语又衔接题。本题我们先从分析选项人手: 选项A)proposing“建议”；选项B)promoting"提示、鼓动、促进"；选项C)suggesting“建议”；这三个选项放入文中意思上都说不通；而选项D)advancing除了大家熟悉的“使进步，增进，发展”的意思外，还有“提倡(理论、看法)”的意思．所以应选advancing，取其最后一种意思．原句大意为；尽管这些说法没有科学依据。但大量书面材料支持这一观点，使得公众难辨真伪．所以答案是D)．
