     There was a time when a trip to the supermarket in the United States often ended with

a seemingly simple question from the (收银员) ：Paper or plastic? Well,which type of bag would you choose?

      While all types of bags have some influence on th^ environment,it has long been supposed that paper b?gs are kinder. TTiey are made from a renewable source,break down easily,bum without giving off thick smoke and can be (回收利用) .However,the proild: process behind paper bags uses more energy than that of plastic ones. How can this be true?

      Studies show that paper bag production requires four times as much energy as plastic bag production. And the (量) of water used to make them is twenty times higher. Besides the influence on forests is very serious. It takes about fourteen million trees to produce ten billion paper bags,which happens to be the number of bags used in the United States yearly. In terms of recycling,the idea that paper bags are more environment-friendly than plastic ones can be quickly discarded. Research shows it requires about 98% less energy to recycle plastic than it does paper.

     Even though paper bags might be more harmful than plastic ones,plastic still seems to be considered by governments as the more harmful of the two. In Ireland,for example,a tax (??) has been introduced to discourage the use of plastic bags. People have to pay 22 cents for every plastic bag,and as a result,their use has dropped quickly.

     There,s no doubt it makes more sense to reuse these bags. However,we don't seem to be doing that at present. That may be because they fall apart quickly. If so,cloth bags are a better choice,but still,their production also has a bad influence on the environment. So what to do? How should we answer the question of “Paper or plastic?” It seems that we first need to ask ourselves one more general question: “What can I ?o to help the environment?”

      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(耳机) ，which sends information about the driver' s brain waves (月凶电波) to a tiny computer. The computer can be placed in front of the driver. The 吵对撕(系统) 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."

    When my grandfather left school,he got his first job as a office worker. In those days,he was extreme thin. He paid very little,so he could not afford to eating a lot. I have one or two photos of her from that time,and he looks just like me,but a lot thin!When he grew older,he worked at all sorts of thing,such as reporting for a local newspaper and worked as a part-time salesman. He worked hardly all his life,but he always found out time for the things he enjoyed,like going fishing on weekends or reading books at home.
