House dust amounts of just three micrograms were shown to affect the cells—far lower than the mass of dust children are exposed to daily. Small amounts of house dust containing compounds of environmental【C1】______could be playing a role in the growth of fat cells.
Researchers from the American Chemical Society have found that compounds called endocrine-disrupting chemicals(EDCs)found in house dust can【C2】______fat cells to accumulate more fat. In the study, fat cells accumulated an【C3】______type of fat called triglycerides as a result of house dust being added to the lab petri dishes.
EDCs are synthetic or【C4】______occurring compounds that can replicate the body’s hormones. Evidence from animal studies has also suggested that early life【C5】______to some EDCs can cause weight gain in later life. EDCs are commonly found in consumer goods and eventually end up in indoor dust. House dust is then【C6】______, ingested and absorbed through the skin. An【C7】______50 milligrams accumulated house dust is consumed every day by children, according to the US Environmental Protection Agency. The researchers collected samples of indoor dust from 11 homes in North Carolina. Extracts from seven of the 11 dust samples triggered the fat cells to【C8】______into mature fat cells and accumulate triglycerides. Only one of the dust samples had no effect.
In nine of the samples, the house dust spurred the cells to【C9】______and by doing so, create a larger pool of precursor fat cells. The fat cells used in the study were mouse cell models which are frequently used to test compounds for【C10】______effects on the accumulation of the triglyceride fats. In one of the 44 house dust contaminants tested, a substance commonly found in plastics was found to have the strongest fat-producing effects.
A)additional I)inhaled
B)artificially J)naturally
C)connection K)pollutants
D)develop L)positive
E)divide M)potential
F)estimated N)spur
G)exhaled O)stir
H)exposure [br] 【C2】
选项
答案
N
解析
空格前是情态动词can,之后是名词词组fat cells,因此此处应填入动词原形。spur sb./sth.to do sth.是固定搭配,意为“促进、刺激、加速某人做某事/某事的形成”,此处指室内灰尘会刺激脂肪细胞积聚更多的脂肪,故N)spur为答案。
