2 . For Canaan Elementary’s second grade in Patchogue, N.Y.，today is speech day ,and right now it’s Chris Palaez’s turn. The 8-year-old is the joker of the class. With shining dark eyes, he seems like the of kid who would enjoy public speaking.

But he’s, nervous.“I’m here to tell you today why you should … should…”Chris trips on the“-ld,”a. pronunciation difficulty for many non-native English speakers. His teacher ,Thomas Whaley ,is next to him, whispering support.“…Vote for …me …”Except for some stumbles, Chris is doing amazingly well. When he brings his speech to a nice conclusion ,Whaley invites the rest of the class to praise him.

A son of immigrants, Chris stared learning English a little over three years ago. Whaley recalls(回想起)how at the beginning of the year，when called upon to read，Chris would excuse himself to go to the bathroom.

Learning English as a second language can be a painful experience. What you need is a great teacher who lets you make mistakes. “It takes a lot for any student，” Whaley explains，“especially for a student who is learning English as their new language，to feel confident enough to say，‘I don’t know，but I want to know.’”

Whaley got the idea of this second-grade presidential campaign project when he asked the children one day to raise their hands if they thought they could never be a president. The answer broke his heart. Whaley says the project is about more than just learning to read and speak in public. He wants these kids to learn to boast(夸耀)about themselves.

“Boasting about yourself，and your best qualities,” Whaley says，“is very difficult for a child who came into the classroom not feeling confident.”

4 . By day, Robert Titterton is a lawyer. In his spare on stage beside pianist Maria Raspopova — not as a musician but as her page turner. “I’m not a trained musician, but I’ve learnt to read music so I can help Maria in her performance.”

Mr Titterton is chairman of the Omega Ensemble but has been the group’s official page turner for the past four years. His job is to sit beside   the pianist and turn the pages of the score so the musician doesn’t have to break the flow of sound by doing it themselves. He said he became just as nervous as those playing instruments on stage.

“A lot of skills are needed for the job. You have to make sure you don’t turn two pages at once and make sure you find the repeats in the music   when you have to go back to the right spot.” Mr Titterton explained.

Being a page turner requires plenty of practice. Some pieces of music can go for 40 minutes and require up to 50 page turns, including back turns for repeat passages. Silent onstage communication is key, and each pianist has their own style of “nodding” to indicate a page turn which they need to practise with their page turner.

But like all performances, there are moments when things go wrong. “I was turning the page to get ready for the next page, but the draft wind from the turn caused the spare pages to fall off the stand,” Mr Titterton said, “Luckily I was able to catch them and put them back.”

Most page turners are piano students or up-and-coming concert pianists, although Ms Raspopova has once asked her husband to   help her out on stage.

“My husband is the worst page turner,” she laughed. “He’s interested in the music, feeling every note, and I have to say: ‘Turn, turn!’ “Robert is the best page turner I’ve had in my entire life.”

5 . Monkeys seem to have a way with numbers.

A team of researchers trained three Rhesus monkeys to associate 26 clearly different symbols consisting of numbers and selective letters with 0-25 drops of water or juice as a reward. The researchers then tested how the monkeys combined—or added—the symbols to get the reward.

Here’s how Harvard Medical School scientist Margaret Livingstone, who led the team, described the experiment: In their cages the monkeys were provided with touch screens. On one part of the screen, a symbol would appear, and on the other side two symbols inside a circle were shown. For example, the number 7 would flash on one side of the screen and the other end would have 9 and 8. If the monkeys touched the left side of the screen they would be rewarded with seven drops of water or juice; if they went for the circle, they would be rewarded with the sum of the numbers—17 in this example.

After running hundreds of tests, the researchers noted that the monkeys would go for the higher values more than half the time, indicating that they were performing a calculation, not just memorizing the value of each combination.

When the team examined the results of the experiment more closely, they noticed that the monkeys tended to underestimate(低估) a sum compared with a single symbol when the two were close in value—sometimes choosing, for example, a 13 over the sum of 8 and 6. The underestimation was systematic: When adding two numbers, the monkeys always paid attention to the larger of the two, and then added only a fraction(小部分) of the smaller number to it.

“This indicates that there is a certain way quantity is represented in their brains, ”Dr. Livingstone says. “But in this experiment what they’re doing is paying more attention to the big number than the little one.”

6 . As data and identity theft becomes more and more common, the market is growing for biometric(生物测量) technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.

Researchers from Georgia Tech say that they have come up with a low-cost device(装置) that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence(节奏) with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to—regardless of whether someone gets the password right.

It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.

In a study describing the technology, the researchers had 100 volunteers type the word “touch” four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.

7 . With the young unable to afford to leave home and the old at risk of isolation(孤独), more families are choosing to live together.

The doorway to peace and quiet, for Nick Bright at least, leads straight to his mother-in-law, she lives on the ground floor, while he lives upstairs with his wife and their two daughters.

Four years ago they all moved into a three-storey Victorian house in Bristol — one of a growing number of multigenerational families in the UK living together under the same roof. They share a front door and a washing machine, but Rita Whitehead has her own kitchen, bathroom, bedroom and living room on the ground floor.

“We floated the idea to my mum of sharing at a house,” says Kathryn Whitehead. Rita cuts in: “We spoke more with Nick because I think it’s a big thing for Nick to live with his mother-in-law.”

And what does Nick think? “From my standpoint, it all seems to work very well. Would I recommend it? Yes, I think I would.”

It’s hard to tell exactly how many people agree with him, but research indicates that the numbers have been rising for some time. Official reports suggest that the number of households with three generations living together had risen from 325,000 in 2002 to 419,000 in 2013.

Other varieties of multigenerational family are more common. Some people live with their elderly parents; many more adult children are returning to the family home, if they ever left. It is said that about 20% of 25-34-year-olds live with their parents, compared with 16% in 1991.The total number of all multigenerational households in Britain is thought to be about 1.8 million.

Stories like that are more common in parts of the world where multigenerational living is more firmly rooted. In India, particularly outside cities, young women are expected to move in with their husband’s family when they get married.

What is Nick’s attitude towards sharing the house with his mother-in -law?

8 . “You can use me as a last resort(选择), and if nobody else volunteers，then I will do it.” This was an actual reply from a parent after I put out a request for volunteers for my kids lacrosse(长曲棍球)club.

I guess that there's probably some demanding work schedule, or social anxiety around stepping up to help for an unknown sport. She may just need a little persuading. So I try again and tug at the heartstrings. I mention the single parent with four kids running the show and I talk about the dad coaching a team that his kids aren’t even on … At this point the unwilling parent speaks up,“Alright. Yes, I’ll do it.”

I’m secretly relieved because I know there’s real power in sharing volunteer responsibilities among many. The unwilling parent organizes the meal schedule, sends out emails, and collects money for end-of-season gifts. Somewhere along the way, the same parent ends up becoming an invaluable member of the team. The coach is able to focus on the kids while the other parents are relieved to be off the hook for another season. Handing out sliced oranges to bloodthirsty kids can be as exciting as watching your own kid score a goal.

Still, most of us volunteers breathe a sigh of relief when the season comes to a close. That relief is coupled with a deep understanding of why the same people keep coming back for more: Connecting to the community(社区)as you freely give your time, money, skills, or services provides a real joy. Volunteering just feels so good.

In that sense, I’m pretty sure volunteering is more of a selfish act than I’d freely like to admit. However, if others benefit in the process, and I get some reward too, does it really matter where my motivation lies?
