1 . When Sarah Wishnia received an iPad from her daughter, “It was like Greek to me.” Max Rosenblum showed her how to socialize on Facebook and shop on Amazon with her new device.With Max's help, Elena learned to give orders to Siri, Mike familiarized himself with Waze and Honey began searching for information about movies, restaurants and books on her smartphone.Max is 16, a rising junior in Davie. His students are residents of Coral Gables, fascinated by technology and eager to learn about this brave new frontier. Max began offering his tech coaching for seniors a year ago, after he helped his grandmother with her iPhone and iPad. He taught her how to text and use Faccbook. He also downloaded a Scrabble app for her to play. “She loved it,”he said, not without a trace of pride.

That experience inspired him and his parents, Adam and Heather. They reached out to a connection at Coral Gables and launched a website, techmaxed. com. He also recruited(招募)other teens to teach the one-on-one lessons in Coral Gables. These youths go to the retirement communities at least once a month. Though teaching a class might appear to be more expedient,soon Max found out that group sessions simply didn't work.“People are at different levels,and it was hard to teach that way," he said. “It's much better to give them individual help.” “Most people come more than once,” he added. “I have my regulars.”

“First he showed me how to get my email on the phone,” Rosen, 88, said, “and then he wrote up a short step-by-step guide for me so I could remember.” Max admits that teaching older adults takes time, but he figures he's also paying it forward.

“Maybe when I'm 87 and there's new technology,”   he said, “somebody will teach me, too.”

2 . The baby is just one day old and has not yet left hospital. She is quiet but alert (警觉的). Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视) starts to lose its focus—until a third, with three black spots, is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?

Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly(随意地)on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise(同样地) when the researchers started with drumbeats and moved to spots.

1. The experiment described in Paragraph 1 is related to the baby's ________.

A．sense of hearing	B．sense of sight
C．sense of touch	D．sense of smell

2. Babies are sensitive to the change in ________.

A．the size of cards	B．the colour of pictures

B．To see how babies recognize sounds.

C．To carry their experiment further.

D．To keep the babies' interest.
