9．I was in the garden with Augie，My four-year-old grandson，watching the bees．"Bees make honey，"I said．After a pause，Augie replied，"How do they make the honey？"There is nothing like a child's question for exposing the limits of a grandmother's wisdom．
"Actually，Augie，I don't know，"I said．
"But，Grandma，you have your phone，"he said．For Augie，a smart phone is as natural as the bees，and holding one is almost equal to knowing．
I Googled"How do bees make honey？"There were dozens of videos explaining it．Augie and I learned that worker bees produce an enzyme（酵素），which changes nectar（花蜜）into dextrose．then beat their wings to thicken the nectar into honey．
"It's kind of hard to see the bees．"I said．
"Why don't we watch it on the big computer？"Augie said．
For the next hour，we sat inside，bee-surfing．There were a lot of beekeeper selfie videos，best of which was a BBC documentary about the"waggle dance，"the remarkable communication system that allows bees to give one another directions to the places where they've found nectar．
Most of my own children was spent reading books，forgetting the world around me．Over time，reading controlled my brain，as large areas once dedicated to dealing with the"real"world adapted to dealing with the printed word．This didn't limit my development，but it didi leave me with some illusions（错觉）-my idea of romantic love surely came from novels．
Many parents worry that"screen time"will harm children's development，but recent research suggests that most of the common fears about children and screens are unfounded．（There is one exception：looking at screens that emit blue light before bed really does disturb sleep，in people of all ages．） The new guidelines emphasize that what matters is content and context，what children watch and with whom．Each child，after all，will have some hundred thousand of conscious experience before turning sixteen．Those hours can be like the wonderful ones that Augie and I spent together bee-watching，or they can be mindless-and that's true whether those hours are occupied by apps or TV or books or just by talk．
New tools have always led to panic．Socrates thought that reading and writing would have disastrous effects on memory； the novel，the telegraph，the telephone，and the television were all declared to the End of Civilization，particularly in the hands of the young．Part of the reason may be that adult brains require a lot of focus and effort to learn something new，while children's brains are designed to master new environments naturally．Advanced technologies always seem disturbing to the adults attempting to master them，and obvious to those children，like Augie．
Like the bees，we live by the reports of others．Unlike the bees．We can invent new worlds．，constructing them out of apps or TV or books．Sometimes those worlds confuse； at other times，they tell us something inspiring．When Augie's father got home，Augie rushed to meet him in excitement．"Daddy，Daddy，look，"he said，reaching for the phone．"Do you know how bees make honey？I'll show you…？
