Tap water that has been left to sit out slowly begins to acquire an off taste. Many people think that this is because of microorganisms . But that's not what makes old water taste not fresh. For that we can thank carbon dioxide. After about 12 hours, tap water starts to go flat as carbon dioxide in the air starts to mix with the water in the glass, lowering its pH and giving it an off taste. But it's most likely safe to drink. However, back to those microorganisms. If you use a dirty glass day after day, there is more of a chance of bacteria making themselves known; a risk that increases if you share the glass with another mouth as well. But assuming you use a fresh glass every few days, you probably won't have a problem unless the glass has been touched by dirty fingers, and especially if those dirty fingers went unwashed after using the bathroom. As for plastic water bottles that have been left out in the sun or in the car, step away from the bottle, warns Dr. Kellogg Schwab, director of the Johns Hopkins University Water Institute. "A chemical called bisphenol-A, or BPA, along with other things used to make plastic can leach into your water if the bottle heats up or sits in the sun," he explains. BPA, as you probably know, has been linked to everything from heart disease to cancer. Schwab also adds that plastic used for commercial bottled water isn't meant to be washed or refilled, so use only one time and recycle. Or don't buy them at all; use refillable water bottles instead. Question: Tap water begin to acquire an off taste because of _ . Options: A: BPA B: the glass C: the microorganism D: carbon dioxide

Article: Students who work during term time to support themselves at university are far more likely to graduate with a poor degree, according to a government-funded study published yesterday. Undergraduates with part-time jobs are a third less likely to get a first or upper second-class degree than other students, harming their career chances. Students from the poorest backgrounds were most likely to take jobs during term because they could not depend on help from their parents. The report, commissioned by the Department for Education and Skills, also found a clear relation between fear of debt and employment in non-graduate jobs. Students from poorer backgrounds are known to be more unwilling to be in debt than those from middle class families. The study of 8,600 people who graduated in 1999 was made by Peter Elias, of Warwick University, and Kate Purcell, from Bristol Business School. They found that twice as many first-class degrees were awarded to students who did not work during term compared with those who did. Between 35 and 38 percent who worked during term achieved a lower second, compared with about 28 percent of those who did not. Professor Elias said that the increase in school fees next year to PS3,000 would have to be monitored carefully for its effect on poorer students. "Higher education is going to be a harder struggle for those who do not come with all the advantages," he said. He suggested that universities could get in touch with employers to provide work experience on good salaries to choose students during holidays, so that they did not have to work during term. Question: Why did lots of students take term-jobs at university? Options: A: No one would lend them money to continue their study. B: They wanted to improve themselves by taking part-time jobs, C: Their families were poor and couldn't afford the high expense. D: They thought earning money was more important than studying.
