University of Maryland student Ben Simon and his friends couldn't stand to see good food thrown out on their campus."We basically noticed that some of the extra food from the dining hall was going to waste at the end of the day.And we met with the dining services and asked them whether it would be okay if instead of throwing out the food we would donate it.And they were on board," he said. So 18 months ago,the students began what they call the Food Recovery Network.Each night,volunteers would show up at a campus dining hall to pick up leftovers and deliver them to area shelters and food banks.So far,they have donated more than 23 000 kilos of food that would otherwise have been thrown out. Nationwide,$165 billion worth of food is wasted each year,according to the National Resources Defense Council.Spokesman Bob Keefe says that is about 40% of the country's entire food production."If we can reduce our waste in this country by 15%,we can feed 25 million hungry Americans.That is a huge benefit.That is what programs like this Food Recovery Network are doing," he said. Christian Life Center is one of the beneficiaries   of the students' efforts.Ben Slye,the senior pastor  ,said,"It has been just amazing to see these students take their own time,their own vehicles and own gas money and be able to make an effort like this.Each week we are able with this food probably to feed over hundred people." The University of Maryland's Food Recovery Network now has 200 volunteers and the program has expanded to 18 schools across the country."I want to grow 18 chapters to a thousand chapters within five years.And once we get to the Food Recovery Nation being at every college campus in America,we want to expand to restaurants and farms." said Simon. The volunteers are committed to making that happen. Volunteers from the Food Recovery Network  _  . A) started the Food Recovery Network two years ago B) delivered leftovers as well as money to shelters C) helped to solve the hunger issues in America D) donated leftovers to avoid food waste

What would it take to persuade you to exercise? A desire to lose weight or improve your figure? To keep you away from diseases? To live to a healthy old age? You'd think any of those reasons would be enough to get Americans exercising. Yet a vast majority of Americans have thus far failed to swallow the "exercise pill". Now a research by psychologists strongly suggests it's time to think of current well-being and happiness as motivators for exercise instead of future health, weight loss and body image. Dr. Segar, one of the researchers, believes that immediate rewards are more motivating than distant ones. "People who say they exercise for the quality of life exercise more over the course of a year than those who say they value exercise for its health benefits." He said. ' Other studies have shown that what keeps people moving depends on age, sex and life circumstances. For those of college age, physical attractiveness typically heads the list of reasons to begin exercising, although what keeps them going seems to be the stress relief that a regular exercise program provides. The elderly, on the other hand, may get started because of health concerns. But often what keeps them exercising are the friendships and sense of community that may otherwise be missing from their lives. Improving daily well-being is the most influential factor for the women. Men indicate they are motivated by more distant health benefits, but this may be because men feel less comfortable discussing their mental health needs. "Exercise should be encouraged but the emphasis on weight loss, disease prevention and healthy aging should be reduced." Dr. Segar concluded. "Exercise can make people feel more energetic, less stressed and, yes, happier." What is the author mainly arguing in the passage? A) Immediate rewards of exercise should be emphasized. B) Distant benefits should be the motivators for exercise. C) Feeling relaxed is more important than future health. D) Men and women take exercise for different purposes.

Children whose minds wander might have sharper brains, a research suggests. A study has found that people who appear to be often distracted   have more "working memory", giving them the ability to hold a lot of information in their heads and control it cleverly. Children at school need this type of memory on a daily basis for a variety of tasks, such as following teachers' instructions or remembering dictated   sentences. During the study, volunteers were asked to perform one simple task during which researchers kept asking if their minds were wandering. At the end, volunteers measured their working memory capacity   by their ability to remember a series of letters mixed with simple maths questions. Daniel Levinson, a professor at the University of Wisconsin-Madison in the United States, said that those with higher working memory capacity reported "more mind wandering during these simple tasks", but their performance did not _ . The results, published online in the journal Psychological Science, appear to confirm former research that found working memory allows humans to deal with multiple thoughts at the same time. Dr Jonathan Smallwood, of the Max Planck Institute for Human Cognitive and Brain Science in Leipzig, Germany, said, "What this study seems to suggest is that, when surroundings for the task aren't very difficult, people with additional working memory capacity use them effectively to think about other things besides what they're doing." Working memory capacity is also associated with general measures of intelligence, such as reading comprehension and IQ scores. Dr Smallwood added: "Our results suggest the sorts of planning that people do quite often in daily life - when they are on the bus, when they are cycling to work, when they are in the shower - are probably supported by working memory." According to the study, working memory   _  . A) prevents people from remembering dictated sentences B) causes people's minds to wander more easily C) allows people to consider more things at the same time D) leads to people's worse performance during work
