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.
"Although this research is still in the early stages there is no doubt that sugar-free yoghurts 【C7】______ a much healthier alternative to sweets and chocolate, and we would encourage snackers to incorporate them into their【C8】______."
However, Dr. Carter stressed that the best way to beat bad breath was by adopting a good oral health routine. This【C9】______brushing twice-a-day with fluoride(氟化物)toothpaste, cutting down on the frequency of sugary snacks and drinks and visiting a dentist【C10】______. [br] 【C2】
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。
