2017年成考专升本英语考试真题：How many non-apple eaters answered survey questions in the research?
题目：【Reading Comprehension】
Eating an apple a day doesn’t keep the doctor away , but it does reduce the amount of trips you make to the drug store per year. That ' s according to a new study that investigates whether there ' s any truth in the old saying.
A team of researchers led by Dr Matthew Davis, of the University of Michigan School of Nursing , asked 8,399 participants to answer survey questions about diet and health. A total of 753 were apple eaters, consuming at least 149g of raw apple per day. The remaining 7 ,646 were classed as non-apple eaters. When both groups answered questions on trips to the doctor and trips to the drug store per year,the apple eaters were found to be 27% less likely to visit the druggist for drugs.
Trips to the doctor were not significantly affected by apple consumption , though. " Evidence does not support that an apple a day keeps the doctor away. However, the small number of US adults who eat an apple a day does appear to use fewer prescription medications, " the study concludes.
Apple eaters were also found to be less likely to smoke and be more likely to have a higher educational attainment than non-apple eaters. While apples do not compete with oranges, they dc: contain some immune (兔疫的) system-increasing vitamin C , which may be why apple-eaters visit the druggist less. With over 8mg of vitamin C per medium-sized fruit, an apple can provide roughly 14% your daily recommended intake.
Previous studies have also linked apple consumption to a lower risk of Type 2 diabetes (二型糖尿病) ,improved lung function and a lower risk of colon (结肠) cancer.
