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．
【C3】
选项 A、those
B、such
C、this
D、these
答案B
解析 结构衔接题。空格后面的products是指上文提到的organic food products，文中没有具体例句，也就是说不存在特指关系，因此选项A) those，选项C) this和选项D) these都不可选。选项B) such作代词. 意思是“这样的人(们)或物”，但它同时还可作形容词“这样的，这种，某一种”；such products即指organic food products"有机食品”。所以答案是B) 。
