                                 B 

        The daily hard work in the office can be extremely exhausting. Staring at a computer screen for eight hours a day seems like modem business practice. It's also a common belief that you 5 re more likely to complete your "tasks if you keep your bottom planted in your chair all day. But that opinion is erroneous. In fact,taking breaks regularly throughout your workday can increase your productivity and creativity as it helps to keep the mental iuices flowing. ,

         A new study in the journal Cognition overturns an old theory about the nature of attention and shows that brief breaks from a task can greatly improve one's  ability to focus on that task for a longer period of time. The study gets to the most important part of what so many of us experience when doing the same task for a long period of time; after a while you begin to lose your focus and your ability to perform the task well. "Basically,if you don 51 take small breaks during the day,you re likely to suffer from exhaustion and won 51 complete your task to the highest level of your ability,” says Alejandro Lleras,the leader of the study.

         In addition,new research shows that your brain can be trained and developed iike a muscle. Mental concentration is part of that training. Just as your muscles  become tired after a workout,so does your brain. It needs a rest to recover and move on.

         So,what can you do if you feel guilty about taking a break during the workday? Remember that taking breaks is a good,necessary thing. We* re trying to prove ourselves and our worth to the company,which makes us think that taking breaks prevents us from achieving our goals,but in fact it's  not. It's  necessary to do your best work.

                                A

                                ★★★★☆

      Nearly every driver has experienced that feeling of great tiredness,where it becomes almost impossible to stay awake at the wheel. 14-year-old Katherine Wu is too young to have experienced this situation firsthand. However slie noticed how difficult it was for her dad to remain awake while driving back from ?ieir femiiy vacations in Florida to their home in Maryland. Her mom had to talk to her dad all the way.

So I created a tool that can be used instead of my mom talking to my dad to make sure he stays awake and is safe,” she says.

       Her inversion ,“Driver's Companion”，can notice driver sleepiness and warn the driver if he or she is too t?ed to be on the road.

     The user wears a headset(耳機) ，which sends information about the driver' s brain waves (月兇電波) to a tiny computer. The computer can be placed in front of the driver. The 吵對撕(系統(tǒng)) then gives warnings,if needed. As the driver becomes sleepier,red color will be shown to warn him or her. The driver will also hear messages warning him to get off the road. The machine can say, “You’ re tired. Please take a break."

      After sending her invention to the 2014 Discovery Education 3M Young Scientist Challenge,Wu was chosen as a finalist and was able to work with Dr. Jesse Miller,who is a product development specialist.

    “He helped me understand how important it IS to make sure that my invention wprked for the people who were using it and that it was user-friendly,” Wu says.

As a young scientist,Wu has some advice for other students of her age: ul would like to tell them that they should choose something they* re interested in. So they 11 be willing to spend more time on it and enjoy working on it more. Also when there 's difficulty,they should just continue working hard because they’ 11 get over it."
