Fructose, found 【C2】______ in honey and fruit, is used widely in foods 【C3】______ from soft drinks to yogurt. But【C4】______ its sweet taste is popular, the sugar could cause wrinkles and health problems, the researchers said. Dr. Moshe Werman and Boaz Levi of the Technion-Israel Institute of Technology 【C5】______ large amounts of fructose to laboratory rats. Writing in the Journal of Nutrition, they said the fructose-fed rats showed changes 【C6】______ the collagen (胶原质) of their skin and bones.
Collagen, a fibrous protein found in connective tissue, bone and cartilage (软骨), basically holds the body together. The 【C7】______ of collagen is what causes sagging (松弛) and deep wrinkles in older people.
The process affected, Werman’s team said, is known as "cross linking". "Too much cross-linking reduces elasticity and makes the skin 【C8】______ and rigid, and these are the conditions that encourage wrinkled skin," Werman said in a statement. He said the same could be true of people, 【C9】______ this has not been shown. "Americans are eating more and more 【C10】______ foods such as carbonated drinks, baked goods, canned fruits jams and dairy products that 【C11】______ fructose," Werman said. Other studies have shown that 【C12】______ fructose intake can affect how the body 【C13】 glucose(葡萄糖) and increases insulin(胰岛素) resistance-which can 【C14】______ be important measures of the 【C15】______ toward diabetes.
The rats Werman worked 【C16】______ were fed much more than the 【C17】______ adult person might eat in a day, which is standard in such 【C18】______ The rats were fed 12.5 grams of fructose per kg (2.2 pounds) of weight every day for a year. To 【C19】______ , a person weighing 154 pounds (70kg) who drinks a quart (liter) of cola 【C20】______ about 60 grams of fructose, or 0.8 grams per kg of body weight.
【C14】______
选项
A、either
B、never
C、both
D、all
答案
C
解析
语义逻辑题。此处指的是破折号前面的“葡萄糖的代谢”和“对胰岛素的抵抗力”两种特征,故选both。既要注意定语从句中关系代词的所指,又要注意是肯定还是否定语气。
