    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】______．

选项 A、proposing
B、prompting
C、suggesting
D、advancing
答案 D
解析 语义衔接题。本题我们先从分析选项入手: 选项A) proposing“建议”；选项B) promoting“提示、鼓动、促进”；选项C) suggesting“建议”；这三个选项放人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: 尽管那些说法多数未被科学验证，但大量的书面材料支持这一观点，使得普通群众难辨真伪。所以答案是D) 。
