1 . What do classrooms, computer desks, cafeterias (自助食堂), and libraries have in common? That’s the places where students spend so much of their time. Although hours of studying burn mental energy, both your body and mind need physical exercise to function efficiently.
The importance of exercise is nothing new. Thomas Jefferson once wrote that to be successful in academic studies, a person should spend two hours on exercise every day, for health must not be sacrificed (牺牲) for learning. A strong body makes the mind strong.
It turns out Jefferson was on to something. A study by researchers at Tufts University found that students who said they exercised at least 3 days a week were more likely to report a better state of physical health and greater happiness than those who didn’t exercise. This and other evidence suggest that the real benefits of exercise may not come right after a workout but from a longer commitment to regular activity.
But experts today do not demand 2 hours of daily exercise. The U.S. Department of Health and Human Services recommends that people get at least 60 minutes of physical activity most days of the week.
Walking, jogging and swimming are easy ways to increase your heart rate and improve health. Exercise can also help lower blood pressure and reduce stress. For women, exercise that makes the body and bones bear weight — like walking or running — may reduce the risk of osteoporosis (骨质疏松) later in life.
You’ll likely discover another benefit of exercise as well: greater self-confidence. This may make it easier for you to participate in class and help you perform well in academic and social situations.

3 . When we’re in trouble, we always turn to our parents for help. But would you like them to hear the conversations you have with your friends on the school playground or lunch queue? Social networking sites have become extensions (延伸) of the school hallways, so would you add your parents as “friends” and allow them to view your online activities and conversations with friends?
In the past the generation gap included a technology gap, where children were up to date with the latest technology and parents were left behind, content to continue their day-to-day lives as they always had because they had no need to know more about technology. However, more and more parents are beginning to realize just how important social networks are in their lives. This realization has given many parents the motivation (动机) to educate themselves about social networking sites.
These days many people are attracted to social networking sites because they can choose who they have around them, there’s also a certain amount of control over privacy (隐私) that we don’t get in real life. Sometimes we feel that privacy is violated (违背) when we must accept a “friend” request from a parent or family member.
It’s a difficult choice whether or not to allow a parent to become a part of our online lives. On the one hand we don’t want to “refuse” their request because that might hurt their feelings or make them feel you have something to hide. On the other hand if you do accept, then you could have a sense of being watched and no longer feel free to comment or communicate the way you did before.
A recent survey suggested that parents shouldn’t take it personally if their children overlook (忽略) their requests. When a teenager overlooks a parent’s friend request, it doesn’t necessarily mean that he is hiding something, but it could mean that this is one part of his life where he wants to be independent.
Perhaps talking with parents and explaining would help soften the blow if you do choose not to add them to your friend list.

5 . Many researchers refer to coral reefs (珊瑚礁) as the rainforests of the sea because they are not only very beautiful but also cuucial to the health of our oceans. Sadly, these delicate ecosystems face they is from pollution and overfishing. In an inspiring cooperatton, Mote Marine Laboratory (MML) and the Combat Wounded Veteran Challenge (CWVC) have joined hands to restore (恢复) the coral reefs off the coast of Kev West, Florida.
On a sunny day in Key West, a group of 31 wounded and injured veteratis, together with six Mote staff members, set out on a misirn to restore the Higgs Head coral reef. Equipped with specialized waterproof prosthulies and a shared determination, the group managed to plant a record-breaking 1,040 corals on the reef.
The planting mission not only belps to replace corals lost to disease, hurricanes and rising water temperatures, but symbolizes the adaptation and strength of both wounded veterans and the coral reefs themselves. Dr. Michael P. Crosby, President of MML stated, “The inspirational CWVC motto ‘I am wounded, not conquered (征服)’ is also applicable to coral reefs in Key West.”
Florida’s populations of coral reefs were once filled with life. The living coral cover, which represents the proportion of the reef covered in living coral, has plummeted from over 30% four decades ago to a mere 1-5% today, however. MML’s research and restoration programs offer hope for the recovery of Florida’s coral reefs and other coral ecosystems worldwide.
As wounded veterans and scientists work side by side to restore coral reefs, the impact of their collective efforts extends far beyond the ocean floor. The restoration missions not only help to heal the wounds of war but also provide a renewed sense of purpose for those who have sacrificed so much. Andrew Lourake, CWVC Vice President confirms, “The challenge, friendship and knowing they are making a difference are the highlight of the year for almost all our participants.”
By combining cutting-edge science, community engagement, and the spirit of resilience (复原), MML and CWVC are paving the way for a brighter future for our coral reefs. They inspire us all to protect and preserve these invaluable ecosystems, ensuring that future generations can wonder at their beauty and biodiversity.

6 . Music is all around us. It’s an accessible and popular art form which accompanies our daily lives. Advertisers have long understood the popularity and emotional power of music and capitalized on it. They spend much time and money securing the right soundtrack (配乐) for an advertisement in order to boost sales. For example, Microsoft spent a reported US$3 million using Start Me Up as part of their advertising campaign for Windows 95.
As one researcher puts it, “Music expands pictures and colors words, and often adds a form of energy available through no other source.” This is supported by other studies, which suggest that music matching the main message of an advertisement has a positive effect on consumer engagement. This is known as “musical congruity” and can result in better attention, a positive emotional response, finally improving the effectiveness of an advertisement.
Take the simple but interesting advertisement for Air France, with the soundtrack of Mozart’s Piano Concerto No.23, for example. It projects greatness and elegance in the hope that viewers will associate those qualities with the airline. The research, which looked at hundreds of viewer comments about the music used in advertising, suggested it was successful.
Music is also effective at arousing (唤醒) emotional memories in advertisements creates associations with consumers’ past experiences. A good choice of music allows businesses to tap into this nostalgia for commercial benefit.
However, the use of popular music in advertising can also arouse arguments between artistic effort and commercialism. Some people believe a work of art shouldn’t be used for the pursuit of profit. The findings of study showed that consumers sometimes passionately oppose the use of music produced by respected musicians in advertisements, as they believe that it destroys the aesthetic integrity (美学完整性). For example, Nike’s use of the Beatles’ song Revolution was seen by some as using John Lennon’s music to sell shoes. It made some Nike wearers so angry that they refused to buy the products.

7 . I recently read Pablo Picasso’s quote, “I’m always doing that which I cannot do, in order that I may learn how to do it.” It reminded me of myself — and how I do, learn, and improve. I recalled one of my earliest memories of doing before learning: baking scones (烤饼) when I was 10 years old. I wanted to bake scones for my mom.
I always sat at the kitchen table when my mom baked, and I had observed her process numerous times. She always used a recipe book and followed the process carefully. As I started to try, I didn’t know I shouldn’t handle the dough (面团) with my hands too much once I had added the baking powder (发酵粉). However, I knew exactly how to roll out the dough and use a cookie cutter to cut the scones, because I had repeated it in my mind hundreds of times.
As my mom arrived home, the smell of freshly baked scones welcomed her into the kitchen. They were baked to golden brown perfection — flat, as a result of over-handling the dough, but they tasted OK. My mom praised me for my attempt, rather than blaming me for the state of the kitchen, which was a surprise! That night she told my dad how proud she was, and what a good job I’d done. Over time, she taught me the finer tricks of baking and cooking.
My habit of doing before learning still stands me in good stead. Whatever computer program or application I have to learn, I do so by simply starting to use it. I learn as I go on, and I’ve often been able to help others because I’ve gone through the process of learning from beginning to end. What I discovered from my experience is the wisdom to know when it’s OK to do and then learn, and when it’s probably better to learn and then do!

8 . If a pancake could dream, it might long for legs so it could jump off your breakfast plate in pursuit of a better, unchewed life. But legs aren’t necessary for something as flat as a pancake to jump around. A group of scientists have designed a pancake-shaped robot that can jump several times per second and higher than seven times its body height. The new robot named Hop, which swiftly jumps without feet, is an important contribution to the soft robotics.
Many ground robots move by rolling or walking. But it’s more efficient for robots to jump over obstacles (障碍物) than to go around them. Although jumping can offer some robots a competitive edge, engineering that ability has been a challenge for robotics researchers. Some soft robots that store energy can perform a single impressive jump very infrequently. Some lightweight soft robots that don’t store energy can jump frequently but can’t jump high or far enough to successfully cross an obstacle.
For inspiration, the researchers looked to gall midge larvae (瘿蚊幼虫) that miraculously throw themselves across distances 30 times as long as their loglike bodies. A gall midge larva bends its body and squeezes the liquid in its body to one end, making it rigid (僵硬的). The accumulation of liquid builds up pressure, and releasing the pressure sends it soaring (飙升). The robot’s body doesn’t resemble (像) that of a gall midge larva, but it jumps like one. Its body is made of two small plastic bags printed with electrodes; the front bag is filled with liquid and the back one is filled with the same volume of air. The robot uses electricity to drive the flow of liquid, which causes the body to bend and generate force with the ground, resulting in a jump. And the air bag imitates the function of an animal’s tail, helping the robot keep a stable position.
While the robot is currently restricted to Earth, it might be right at home exploring another planet. If this is true, the researchers robot might jump over dusty rocks and large holes on the moon or Mars, going where no pancake has gone before.

9 . “I’ll be there in a few minutes. I’m playing a game with a friend, a guy named Snoopy,” my 15-year-old son shouted from his room. “Oh, what is Snoopy’s real name?” I asked. “I have no idea,” he said. “Where is he from?” I continued. He responded, “I think somewhere in Canada. Oh, wait, it doesn’t even matter because Snoopy just left the game and he has been replaced with a robot.” “Your friend is replaced by a robot?” “It doesn’t matter, Dad. It happens all the time! The game continues.” My son doesn’t mind playing with a person or a robot, which is typical of gamers these days. I wonder whether the face-to-face experience of friendship that I grew up with will be lost by our ohildren.
Aristotle, the great Greek thinker and educator. has pointed out that shallow friendship is easily formed but also easily quit because such bonds are weak and uncerturn. Deep friendship, by contrast, is when you care for your friend for his sake, not for any benefit you can get. This is selfless friendship. You can have only a couple of these friends because they require lots of time and effort. You must make sacrifices (牺牲) for each other.
Presence in friendship requires “being with” and “doing for”. Perhaps the most typical feature of deep friendship is “doing for”, as my friend has my back in trouble or brings me soup when I’m sick. Only strong bonds have the power to motivate real sacrifices. But it is unclear why online “friends” would bother to do the hard work of friendship. When I asked my students whether they had people in their lives who would bring them soup when they were sick, they laughed at my Stone Age question and said they’d just order soup online.
Digital life fills and absorbs waking life time so that people do not join in example cases of friendship, like sports, collective arts, free range childhoods, etc. In this way, digital life may produce false friendships.
