A student's life is never easy. {#blank#}1{#/blank#} A lot of preparations are needed so you can be sure to go back home with a diploma and a bright future waiting for you. The following are some basic things you need to do before even seizing that passport and boarding on the plane.

Knowing the country.

    You shouldn't bother researching the country's hottest tourist spots or historical places. You won't go there as a tourist, but as a student. It'll be helpful to read the most important points in their history and to read up on their culture. {#blank#}2{#/blank#} You surely don't want to face legal problems, especially if you're away from home.

Studying their language.

    Don't expect that you can graduate abroad without knowing even the basics of the language. Before leaving your home country, take online lessons to at least master some of their words and sentences. {#blank#}3{#/blank#} Doing this will also prepare you in communicating with those who can't speak English.

    Check the conversion（兑换）of your money to their local currency, set up your bank account so you can use it there, get an insurance, and find an apartment. The Internet or your intended school will be very helpful in finding an apartment and helping you understand local currency.

    Remember, you're not only carrying your own reputation but your country's reputation as well. If you act foolishly, people there might think that all of your country men are foolish as well. {#blank#}5{#/blank#}

A. Packing your clothes.

B. Preparing for other needs.

C. Most importantly, read about their laws.

D. This will be useful in living and studying there.

E. That would surely be a very bad start for your study abroad program.

F. Going with their trends will keep it from being too obvious that you're a foreigner.

G. And it is even more difficult if you will have to complete your study in a foreign land.

    Most kids go to school during the day and come home to their families or caregivers at night．Sometimes kids can't go home every night so they board or live at school during term-time．

    Whatever the reason for going to boarding school, living with a group of people is very different from living with your family．You have to learn to get on with others, be responsible for looking after your own stuff and follow the rules that are there to make everyone's life pleasant and safe.

The following are some tips from boarders.

    "Remember that the other new students are probably as shy as you are．If you don't talk first and try to make friends, it may not happen．"

    "Don't hold things back inside you．The more you talk, the easier it gets．You can talk to older boarders as well as adults．They understand what you are feeling—they've been through it too．"

    "Be respectful of others' space and give them privacy．Having people around all the time means you don't get much time to yourself."

    "Join in sports and other afterschool activities．You'll meet lots of new people who are interested in the same things as you．And keeping busy will help you get over feeling homesick．"

    "If you are a weekly boarder or go home most weekends it can be harder to make friends, so see if you can organize to stay in for a weekend."

    "Make friends with non-boarders too．It's good to visit someone's home sometimes."

    "Boarding has its ups and downs, you get homesick and sometimes the food is not that great but most of the time it is like being in one big family．You make friends that you know you'll keep for the rest of your life．"

    Sometimes just when we need the power of miracles to change our beliefs, they materialize in the places we'd least expect. They can come to us as a great change in our physical reality or as a simple coincidence in our lives. Sometimes they're big and can't be missed. Other times they're so subtle that if we aren't aware, we may miss them altogether. They can come from the lips of a stranger we suddenly and mysteriously meet at just the right instant. If we listen carefully, we'll always hear the right words, at the right time, to dazzle (目眩) us into a realization of something that we may have failed to notice only moments before.

    On a cold January afternoon in 1989, I was hiking up the trail that leads to the top of Egypt's Mt. Horeb. I'd spent the day at St. Catherine's Monastery and wanted to get to the peak by sunset to see the valley below. As I was winding up the narrow path, I'd occasionally see other hikers who were coming down from a day on the mountain. While they would generally pass with simply a nod or a greeting in another language, there was one man that day who did neither.

    I saw him coming from the last switchback on the trail that led to the backside of the mountain. As he got closer, I could see that he was dressed differently from the other hikers I'd seen. Rather than the high-tech fabrics and styles that had been the norm, this man was wearing traditional Egyptian clothing. He wore a tattered, rust-colored galabia and obviously old and thick-soled sandals that were covered in dust. What made his appearance so odd, though, was that the man didn't even appear to be Egyptian! He was a small-framed Asian man, had very little hair, and was wearing round, wire-rimmed glasses.

    As we neared one another, I was the first to speak, "Hello," I said, stopping on the trail for a moment to catch my breath. Not a sound came from the man as he walked closer. I thought that maybe he hadn't heard me or the wind had carried my voice away from him in another direction. Suddenly he stopped directly in front of me on the high side of the trail, looked up from the ground, and spoke a single sentence to me in English, "Sometimes you don't know what you have lost until you've lost it." As I took in what I had just heard, he simply stepped around me and continued his going down the trail.

    That moment in my life was a small miracle. The reason is less about what the man said and more about the timing and the context. The year was 1989, and the Cold War was drawing to a close. what the man on the trail couldn't have known is that it was during my Egyptian pilgrimage (朝圣), and specifically during my hike to the top of Moses's mountain, that I'd set the time aside to make decisions that would affect my career in the defense industry, my friends, my family, and, ultimately, my life.

    I had to ask myself what the chances were of an Asian man dressed in an Egyptian galabia coming down from the top of this historic mountain just when I was walking up, stopping before me, and offering his wisdom, seemingly from out of nowhere. My answer to my own question was easy: the odds were slim to none! In a meet that lasted less than two minutes on a mountain halfway around the world from my home, a total stranger had brought clarity and the hint of a warning, regarding the huge changes that I would make within a matter of days. In my way of thinking, that's a miracle.

    I suspect that we all experience small miracles in our lives every day. Sometimes we have the wisdom and the courage to recognize them for what they are In the moments when we don't, that's okay as well. It seems that our miracles have a way of coming back to us again and again. And each time they do, they become a little less subtle, until we can't possibly miss the message that they bring to our lives!

The key is that they're everywhere and occur every day for different reasons, in response to the different needs that we may have in the moment. Our job may be less about questioning the extraordinary things that happen in our daily lives and more about accepting the gifts they bring.

    You may have heard that humans only use ten percent of their brain, and that if you could unlock the rest of your brainpower, you could do so much more. You could become a super genius, or acquire psychic powers like mind reading.

    This "ten-percent myth" has inspired many references in the cultural imagination. In the 2014 movie Lucy, for example, a woman develops godlike powers thanks to drugs that release the previously inaccessible 90 percent of her brain.

    Contrary to the ten-percent myth, however, scientists have shown that humans use their entire brain throughout each day.

    Over the years, brain scientists have shown that different parts of the brain are responsible for specific functions, whether it's recognizing colors or problem solving. Contrary to the ten-percent myth, scientists have proven that every part of the brain is integral for our daily functioning.

    Research has yet to find a brain area that is completely inactive. Even studies that measure activity at the level of single neurons(神经元) have not revealed any inactive areas of the brain.

    Many brain imaging studies that measure brain activity when a person is doing a specific task show how different parts of the brain work together. For example, while you are reading this text on your smartphone, some parts of your brain, including those responsible for vision and reading comprehension, will be more active.

    A more direct counter to the ten-percent myth lies in individuals who have suffered brain damage – like through a stroke(中风)– and what they can no longer do, or do as well, as a result of that damage. If the ten percent myth is true, then damage too many parts of our brain shouldn't affect your daily functioning. Studies have shown that damaging a very small part of the brain may have devastating consequences.

    If someone experiences damage to Broca's area(布罗卡氏区), for example, they can understand language but can't speak fluently.

    In one highly publicized case, a woman in Florida permanently lost her" capacity for thoughts, perceptions, memories, and emotions that are the very essence of being human" when a lack of oxygen destroyed half of her brain.

    Scientists Diego Kersting and Cristina Linares have found that some coral species are able to recover from harmful warming events through a unique survival strategy (策略)—known as "rejuvenescence" (新生)—among corals in the Mediterranean Sea. The findings represent some rare good news for corals around the world, which are facing numerous severe threats—most notably, climate change.

    "The main threats are climate change, overfishing, pollution and coastal urbanization," Kersting said. "But currently, climate change is probably the one causing the most coral cover declines. Warming stresses corals up to a point that may cause death. Some corals bleach (白化) before dying. Other corals do not bleach but die directly." He went on, "Our findings are significant because this survival strategy was only known from fossil corals that existed hundreds of millions of years ago. It is the first time that it has been found in a living coral. Thanks to our findings, we know now that some corals are able to recover, but unfortunately this is not enough in the current climate change context."

    For their research, Kersting and Linares monitored 243 colonies of the endangered reef-building coral Cladocoracaespitosa in Spain's Columbretes Islands Marine Reserve over 16 years, starting in 2002. The monitoring revealed that Cladocoracaespitosa in the Mediterranean uses rejuvenescence to cope with warming events. This process involves the polyps — or the individual coral animals in a colony—shrinking inward and abandoning their skeletons (骨骼) during warm periods, before rejuvenating at a later point. "What happens is that some polyps in a coral colony—sometimes just one— reduces completely its dimensions and partially retreats from its skeleton," Kersting said. "Once the stressful event is over, the shrunken or rejuvenated polyp recovers its size and builds up a new skeleton. Eventually, it begins to reproduce itself through budding and begins to cover the dead colony surfaces."

    He continued, "The results were very surprising because I started to observe colonies that were dead years ago, that were showing living parts many years after their death."
