问题     Consumer products such as shampoos and sunscreens, even ones boosted as safer, may contain potentially harmful chemicals not listed on their labels, according to a study out today that tested dozens of them. Chemicals that【C1】________hormones or affect health were found in all 42 of conventional products sampled, as well as in most—32 of 43—of the alternative products【C2】________as safer, including some by Seventh Generation, the study says. The scientific group studies the【C3】________between the environment and women’s health. "It was【C4】________," says Julia Brody, co-author of the findings. She says consumers using a typical array of products are【C5】________many harmful chemicals.
    Seventh Generation, which makes six of the alternative products tested, welcomed the study’s goal of e-ducating consumers【C6】________questioned its method. Martin Wolf, its director of product sustainability, says the company【C7】________none of the chemicals the study found in three of its products. "The fact that trace amounts were found raises questions" about possible cross-contamination in either【C8】________or testing, he says. "There are so many【C9】________chemicals in this world that they’re finding their way【C10】________everything. "
    John Spengler, a professor of environmental health at Harvard School of Public Health, who was not【C11】________ the study, says the work is "very important" for improving health concerns and【C12】________companies to possible cross-contamination in products, whether from the supply【C13】________or the packaging. "You don’t want to worry people【C14】________a reasonable extent," he says, adding that trace amounts of some chemicals may not pose a problem.【C15】________, he says, there’s an "interactive" accumulating effect from broad use of chemicals,【C16】________it’s important to look at them as a group. The study, which tested for 66 chemicals and found 55 of them in the products, says sunscreens and fragrant products had the most【C17】________chemicals and some of the highest concentrations. Brody, who says there needs to be a more【C18】________listing and testing of a product’s ingredients,【C19】________consumers to use fewer products, seek plant-based ingredients and rely on【C20】________ water, baking soda and vinegar for cleaning.
【C14】
选项 A、beyond
B、to
C、within
D、from
答案A
解析 John Spengler教授说到某些微量的化学物质不一定会引发不良后果，说明人们不用过度担心。beyond a reasonable extent表示“超出合理范围”，此处可表示“过度”，不想让人们过度担心，符合语义逻辑，故选A项。B项to、C项within与a reasonable extent搭配后分别表示“达到一个合理的程度”、“在合理的程度内”，与句中的否定don’t want to worry people一起使用后表示对人们合理担心进行否定，逻辑不对。D项form无法与a extent构成搭配，不选。
