【正文】 to eat if you pick it up in five seconds or less. But is that true?Professor Anthony Hilton from Ashton University, UK, tested the rule with his students. They found that food dropped for five seconds is less likely to contain bacteria(細(xì)菌) than if it sits there for longer.For the study, Hilton and his students tested a lot of food—bread, pasta, cookies and candy—to see how much bacteria they had when they made contact with the floor. They allowed the food to lie on various types of flooringcarpet, laminate(復(fù)合地板), and tile (瓷磚) for three seconds to 30 seconds.Not surprisingly, the longer the food was on the floor, the more bacteria it had. And the type of floor where the dropped food landed had an effect. Bacteria are least likely to transfer from carpet, while they’re most likely to transfer from laminate or tiled surfaces after more than five seconds.The study also found that the wetter the food, the more likely it was to pick up bacteria. Although most people are happy to follow the 5second rule, eating food dropped on the floor still carried an infection(感染) risk. ＂It very much depends on which bacteria are on the floor at the time,＂ Hilton told Forbes.9．What is the ＂5second rule＂ about?A．People often shout at someone when they drop food on the floor.B．Food is safe when you pick up off the floor in less than five seconds.C．It’s better to eat dropped food when it’s been on the floor for over five seconds.D．Food will go bad when dropped on the floor in five second or less.10．Hilton’s test wanted to find out ________.A．if the ＂5second rule＂ is trueB．the students’ favourite foodC．which food is easily droppedD．if different types of floor have different bacteria11．According to the test, we learn the following EXCEPT ________.[來(lái)源:]A．the dropped food had more bacteria if it sat on the floor for longerB．the dropped food on carpet had the least bacteriaC．bacteria was impossible to transfer from laminate or tied surfacesD．the wetter food was more likely to pick up bacteria12．According to the article, the infection risk of the dropped food does NOT depend on _______.A．how long the food sits on the floor B．what the dropped food wasC．what the bacteria are D．what the weather is like that dayD You know the feeling that you have left your phone at home and feel anxious, as if you have lost your connection to the world. “Nomophobia” (無(wú)手機(jī)恐懼癥) affects teenagers and adults alike. You can even do an online test to see if you have it. Last week, researchers from Hong Kong warned that nomophobia is infecting everyone. Their study found that people who use their phones to store, share and access personal memories suffer most. When users were asked to describe how they felt about their phones, words such as “hurt” (neck pain was often reported) and “alone” predicted higher levels of nomophobia.“The findings of our study suggest that users regard smartphones as their extended selves and get attached to the devices,” said Dr. Kim Ki Joon. “People experience feelings of anxiety and unpleasantness when separated from their phones.” Meanwhile, an American study shows that smartphone separation can lead to an increase in heart rate and blood pressure.So can being without your phone really give you separation anxiety? Professor Mark Griffiths, psychologist and director of the International Gaming Research Unit at Nottingham Trent University, says it is what is on the phone that countsthe social networking that creates Fomo (fear of missing out).“We are talking about an internetconnected device that allows people to deal with lots of aspects of their lives,” says Griffiths. “You would have to surgically remove a phone from a teenager because their whole life is rooted in this device.”Griffiths thinks attachment theory, where we develop emotional dependency on the phone because it holds
