Sugarless yoghurt could help beat bad breath, tooth decay and gum disease, say scientists.
Japanese researchers found eating the yoghurt【C1】______ levels of hydrogen sulphide(硫化物)— a major cause of bad breath—in 80% of volunteers. The keys are active bacteria in yoghurt.
Details were presented at a meeting of the International Association for Dental Research. A total of 24 volunteers who【C2】______ in the study were given strict instructions on oral hygiene, diet and medication intake. They spent two weeks【C3】______ yoghurts and similar foods, like cheese. Researchers then【C4】______bacteria levels and odour-causing compounds, including hydrogen sulphide.
The volunteers then ate 90 grams of yoghurt a day for six weeks. At the end of the study, researchers took【C5】______again. They found hydrogen sulphide levels decreased in 80% of participants.
Dr. Nigel Carter, chief executive of the British Dental Health Foundation, said: "The foundation has long been drawing people’s attention to sugar-free yoghurts as a【C6】______ snack, so it is pleasing to hear that it may have oral health benefits we were previously unaware of.

选项
答案
H
解析
空格位于修饰主语volunteers的定语从句中,该从句缺谓语,且空格后有介词in,故此空应填不及物动词;再根据主句的时态(were given...),可知空格处应填入动词的过去式。词库中符合这一要求的只有participated“参与”,代入后表示“这24名志愿者就是参与了该项研究的被试对象”,符合句意。
