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】______.
【C9】
选项
答案
O
解析
本句缺谓语,空格处应填入动词。This回指上一句提到的a good oral health routine“良好的口腔卫生习惯”,而空格后的三个动名词短语描述的都是良好的口腔卫生习惯,由此判断主语和宾语之间属于包含与被包含的关系。词库中的involves可表示某种行为“包含”某种具体做法,符合句意;而干扰项contains“包含;容纳”主要是指某物中“含有”某种成份或者容器中装有某物,与此处语境不符。
