考题 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 docontain some immune (免疫的) 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.44.

考题 The year 2000 will bring big changes in communication.Cell phones will be small enough to carry in your pocket.Videophones will let you see the person you are talking to on the phone.Tiny hand size computers will know your favorite subjects.The Internet and email will be everywhere.Technologists believe 2000 will be the year of video messaging.You will be able to see whom you're talking to.

Some day everything may be connected to the Internet.Your refrigerator will add milk to your Internet grocery list when the date on the carton has passed.Light bulbs will be ordered before they burn out. It's fun to try to guess the future.Usually the predictions are wrong.The one thing we know for sure is that we can't imagine how technology will change.
