Tom was one of the brightest boys in the year,with supportive parents.But when he was 15 he suddenly stopped trying.He left school at 16 with only two scores for secondary school subjects.One of the reasons that made it cool for him not to care was the power of his peer（同龄人）group.

    The lack of right male role models in many of their lives—at home and particularly in the school environment—means that their peers are the only people they have to judge themselves against.

    They don't see men succeeding in society so it doesn't occur to them that they could make something of themselves.Without male teachers as a role model,the effect of peer actions and street culture is all-powerful.Boys want to be part of a club.However,schools can provide the environment for change,and provide the right role models for them.Teachers need to be trained to stop that but not in front of a child's peers.You have to do it one to one, because that is when you see the real child.

    It's pointless sending a child home if he or she has done wrong.They see it as a welcome day off to watch television or play computer games.Instead,schools should have a special unit where a child who has done wrong goes for the day and gets advice about his problems—somewhere he can work away from his peers and go home after the other children.

    We have a strange obsession with the concept of perfection. “If I have the perfect parents and perfect grades, then I would be happy.” Under cultural influence, we seek what we can't have without remembering that we don't actually need to be perfect. Imperfection allows us to be human.

    Parents, teachers and other high-achieving peers will have us believe that we must be perfect if we wish to remain competitive. However, what job or school requires you to have a 2400 SAT, 4.0 GPA and develop a cure for some form of cancer by the age of 18? Although these would be great achievements, are they worth the cost of sleep? We feel like we need the perfect grades to get into the perfect college that will provide us with the perfect education necessary to obtain the perfect job. With this misconception, when writing our resumes(简历), we then seek out experiences that we think may help build a good name for ourselves. Feeding on our thirst for perfection, some college and career industries have been set up claiming to help us reach our goals.

    The truth is, you only need to be good enough. Don't worry about anything secondary to your passions. You won't become an expert at anything if you spend your time trying to succeed in everything you do. You only become an expert when you devote your time to the one or two projects that truly bring you joy.

    As members of this society, we have a responsibility to be excellent in what we do, not perfect. Although perfection can be a goal, it should not be the only goal. We only have 24 hours in a day. Thus, we need to prioritize(优先选择)what we want to do and cut out the activities we cannot do. If you enjoy debating, take a law class and see how it suits you. If you enjoy cooking, experiment in the kitchen and see what you can make!

    Try as hard as you can and let your future worry about itself. Worry about your task at hand and you will be successful in achieving your dreams. Above all, remember that you are going to be okay.

    As free as they make us, mobile phones still need to stay close to a power source. Soon that may change with "green" power.

    Three Chilean students got the idea for a plant-powered device(装置) to charge（使……充电） their cellphones, while sitting in their school's outdoor courtyard during a break from exams, with dead mobile phones. Then, one of them had an "aha" moment.

    “It occurred to Camila to say about plants,” said inventor Evelyn Aravena. “'Why don't you have a socket, if there are so many plants? 'After that, we thought, 'why don't they have a charging outlet（插座）? Because there are so many plants and living things that have the potential to produce energy, why not?'”

    Their invention—a small biological circuit called E-Kaia—uses the energy plants to produce during photosynthesis(光合作用). A plant uses only a small part of that energy and the rest goes into the soil, and that's where the E-Kaia collects it. The device plugs into the ground and then into your phone.

    "It's the most amazing project I've ever seen in my life, plain and simple. They brought this original model, and it worked — and that's when it all changed, at least from my personal point of view and I began to support them." said Mauricio Cifuentes.

    The device solved two problems for the engineering students — they needed an idea for a class project, and an outlet to plug in their phones.

    "Looking for a place to charge the notebook, which had no power, and the mobile phones, we weren't able to find anything because all the other students were in the same state of madness trying to find a place to charge their devices," said Aravena.

    But plants are everywhere, and the bio－circuit makes good use of their excess(过多的) power.

    The E-Kaia doesn't carry much charge but it's powerful enough to completely recharge a mobile phone in less than two hours.

    The student inventors have applied for patents（专利） on their technology, and expect the E-Kaia to go on sale in the near future.

    I live in the center of the city and there is a largeparking lot full of parking spots nearby. Rain is a rare occurrence in LA,so cars easilycollect pollutants and dust. Together with my friends,I decided it shouldbe a kind gesture to surprise the owners with a car wash.So we bought carwashing supplies and brought out all the bath towels we could find.With all the suppliesin hand, wewere able to convince another roommate to help out as well and we beganwatering down the cars.

    Every once in a while, someone would come by and asked usseemingly stupid men, "Who told you to wash the cars?" or, even better, "who paid you to wash their cars?" Weexplained we just wanted to do something kind. But our response was often me with aneven more confused look.

    As the afternoon went on, some other friends that came byunderstood our goal of the spontaneous event and started helping out with someof the duties. Firstone friend then two, and by the time we had cleaned the entire lot,we had an entire carwashing crew with independent individually assigned tasks and duties.

    I wasn't cleaning cars to be able to afford a new phone.I was cleaning carssimply because I wanted to offer the car owners kindness.There was noequipment to weigh our value created. We couldn't measure our success indollars earned over the time spent washing cars when we could have been earningtwice as much at work.

    I now realize, first hand, that there is a special energy createdwhen you choose to think bigger than yourself and act in service of others andmaybe, likeme, you'llfind it's actually the greatest gift you' you'll ever get.

Lizzie's diary from Antarctica (南极洲)

Day 3: Tuesday   December 2

    We planned to go to Rothera that morning. We'd be staying there for the next two weeks. Because Antarctica is the windiest place on earth, sometimes you can't fly at all.

    We had a nervous wait over breakfast to find out if we'd be leaving that day. People have to stay in Stanley for weeks while the pilots wait for good weather.

    It turned clear at 9:30 and we took off at 10:30 on a little red plane called a Dash-7. But even when we were in the air, there was still a chance we wouldn't be able to fly the whole day.

Day 4: Wednesday   December 3

    After waking up in the Antarctic for the first time today I can understand why everybody who comes here falls in love with the place. It is really beautiful.

    We're staying at Rothera Survey base with mountains of ice all around. It is about minus 2⁰C today, which for me is very cold, but the regulars(常客) here are often seen walking around in T-shirts !

Day 5: Thursday   December 4

    I woke up to another beautiful sunny day here in the Antarctic. I'm told it's a bit colder today, about minus 5⁰C, but it's not very windy so it feels warmer. Those of us who are new to the base have to do a special training course before we're allowed to go off base to other stations or to go snowboarding over the nearby hill.

Day 7:  Saturday   December 6

    Not a cloud in the sky and it's warm enough to sit outside (in a jacket).

    The most amazing thing about this place is how the scenery (风景) changes every day.

    At first I thought I was going mad. I'd step outside in the morning and think, "I'm sure that big mountain of ice wasn't there yesterday." It's because the sea ice is always moving—slowly thankfully !

Writing out the same word again and again may bring back bad memories for some, but handwriting can boost connectivity across brain regions, some of which are involved in learning and memory, a new study shows. 

In the study, psychologists Audrey and Ruud, both at the Norwegian University of Science and Technology, stuck electrodes（电极）on the participants' heads. They asked the participants to type out or handwrite with a digital pen words that appeared on a computer screen. Sensors in a cap recorded electrical brain activity. Then the psychologists looked for when two brain areas are active with the same frequency of electrical waves at the same time. This result can reveal the connectivity among different regions across the brain. 

With handwriting, the researchers saw increased activity, specifically in low frequency bands, not only in the expected motor areas but also in others associated with learning. These low frequency bands have previously been shown to support memory processes. When the team compared the two tasks, they realized that handwriting—but not typing—increased the connectivity across parietal（顶叶）brain regions, which are involved in sensory and motor processing, and central regions, many of which are involved in memory. "Even when the movements are very similar, the activation seems much, much higher in handwriting," Audrey says. "It shows that there's more involvement of these brain regions when you're handwriting, which might give you some specific advantages."

These findings suggest that there are distinct processes of brain activation happening while a person types or writes. This boost of stimulation of handwriting facilitates learning because these particular waves between these areas are involved in memory formation and encoding（编码）. 

And although handwriting may help with learning processes, typing is often easier, faster and more practical. "Students and teachers alike should therefore consider the task at hand to decide to handwrite or type, "Audrey says. Despite the need for more studies to determine the best learning strategy, experts say that handwriting shouldn't be left behind in the digital age. "Schools need to bring in more writing into curriculum design," Ruud says.
