What’s the best way to remember our happiest moments, like a birthday or festival? I bet you would answer , “Take lots of photos!” Well, here is a great surprise. People who always take photos may actually be harming(伤害) their memory, because they’re not concentrating on the event itself. That’s according to new research by Fairfield University, Connecticut, in the US. They call this the “photo-taking impairment(损害) affect”.

“People so often take out their cameras almost mindlessly to catch a moment, to the point that they are missing what is happening right in front of them,” Henkel and her team decided to perform an experiment. They wanted to find out whether taking photos in a museum weakened(减弱) a visitor’s memory of what they had seen. So they simply told a group to look around the museum, and either take photos of the items on display, or try to remember what they had seen. In addition(另外), the amount(数量) of detail(细节) they remembered was worse than those who didn’t take photos. “These results show how the mind’s eye and the camera’s eye are not the same,” said Henkel.

But don’t put your camera down just yet. Other studies have found that looking back at old photos helps us remember an event, compared to just taking a photo and forgetting about it. So next time you’re thinking of taking a photo, just think: is it better to look at the beauty around you with your own eyes, or behind the eye of the camera?

在日常生活中如取款、上网等都需要密码.有一种用“因式分解”法产生的密码,方便记忆.原理是:如对于多项式x4﹣y4,因式分解的结果是(x﹣y)(x+y)(x2+y2),若取x=9,y=9时,则各个因式的值是:(x﹣y)=0,(x+y)=18,(x2+y2)=162,于是就可以把“018162”作为一个六位数的密码.对于多项式4x3﹣xy2,取x=10,y=10时,用上述方法产生的密码是:(      )(写出一个即可).
