Thanks to expensive data fees, you might be tempted to log onto that free public Wi-Fi service while you're out and about.{#blank#}1{#/blank#}

    “Think about the cost of being connected all the time. Nothing is free,” David Lee, a product manager for Norton, told CNBC. “{#blank#}2{#/blank#}” The Harvard Business Review agrees: “You're taking a risk every time you log on to a free network in a coffee shop, hotel lobby, or airport lounge.”

    {#blank#}3{#/blank#} According to a survey by the company Symantic, 87 percent of U.S. consumers have used a public internet connection. And it was found that over 70 percent of them checked their personal email through public Wi-Fi, while 11 percent logged onto their online banking account.

    No matter how safe the Wi-Fi connection seems to be, using it leaves your computer or smart phone easy to be attacked by hackers and data thieves. You don't really know who owns and monitors that router, nor who has access to the data that posses through it. Not to mention, hackers have dozens of ways to compromise public Wi-Fi accounts, from creating a network that appears legal to creating pop-ups that trick the user into downloading malware (恶意软件) onto their computers.{#blank#}4{#/blank#}

    To protect yourself against hackers, experts say your best defense is a virtual private network (VPN), which encrypts (加密) your online activity. You can download your very own VPN through an app for Apple or Android devices, or by using the free encryption service CyberGhost{#blank#}5{#/blank#} But before you even start browsing, use this website to make a password that keeps you safe from hackers.

A. These are all of the tricks hackers use to hack your Internet security.

B. That can save you a lot of trouble.

C. The biggest threat is that your data and identity could be completely exposed.

D. Don't let convenience outweigh the consequences, though.

E. Setting up firewalls and antivirus software will also defend your computer against hackers.

F. Unfortunately, most people are unaware of the dangers.

G Hackers usually steal data in this way.

    Our series The Genius Behind will take you inside the minds of people who are making the impossible possible. Whether it is designing the fastest ever land vehicle, helping the blind to see or creating space history, success relies levels of knowledge to new heights . What can we learn about genius from minds? Based on the people and the projects outlined in the series, we've come up with five lessons.

    Lesson one: New challenges require new ways of thinking

    Bloodhound SSC aims to be the first vehicle to break the 1,000 mph barrier. One of the key challenge has been to design the wheels. Thinking twice, Mark Chapman, chief engineer decided to change the way they were trying to solve problems and came up with a wheel design, part car, part jet fighter and part spaceship, which would hold together and was strong enough.

    Lesson two: Let evidence share your opinion

    Geophysicists widely believed that water on Earth originated from comets. But by studying rocks, Steven Jacobsen discovered water hidden inside, suggesting that the oceans gradually made its way out of the planet's interior many centuries ago. “Unfortunately, I had a pretty hard time convincing others,” he admits. Only time can tell whether the new theories are true.

Lesson three: It really is 99% efforts

    Sheila Nirenberg at Cornell University is trying to develop a new prosthetic device(假肢器官)for treating blindness. “Sometimes I'm exhausted and I get burnt out,” she adds. “But then I get an email from somebody saying that they can't see their own children's faces, and it is like, 'How can I possibly complain? Once I thought of this, I couldn't eat, I couldn't sleep—all I wanted to do was work'. It gives me the energy to just go back and keep doing it.”

    Lesson four: The answer isn't always what you expect

    Sylvia Earle has spent decades trying to see the ocean with new eyes. Her “dream machine” is a submarine that could take scientists all the way to the bottom of the deepest ocean floor what sort of material could best withstand the types of pressure y would encounter thousands of miles below the ocean surface?” It could be steel, it could be titanium, it could be some sort of ceramic, or some kind of aluminium system,” says Earle. “But glass is the best choice.”

    Lesson five: A little luck goes a long way

    It was considered as one of the biggest success stories in the history of space exploration—20 years of planning ended earlier this year with the Philae lander landing safely Comet 67P over 300 million miles(480 million kilometers)away from Earth, though Philae's anchoring harpoons(锚定鱼叉)didn't fire as planned.

    As a matter of fact, genius is difficult to define. “Genius is a funny word,” says Nirenberg. “I just sort of ignore it and just go on with life. You just do what you do regardless of whatever label's attached to you. I don't know really how else to explain it.

    Most of us lead unhealthy lives; we spend far too much sitting down. If in addition we are careless about our diets, our bodies soon become loose and fatty and our systems slow moving.

    {#blank#}1{#/blank#}I am thinking of such features of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other. While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them.

    For those who do not particularly enjoy competitive sports—{#blank#}2{#/blank#}—there are such separate activities as cycling, walking, jogging and swimming. What often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are doing yourself much good, except for the fact that you have at least managed to get up out of your armchair.

    Even after you have found a way for keeping in shape, through sport or gymnastics, {#blank#}3{#/blank#}, because, according to the experts, you must also master the art of complete mental and physical relaxation. {#blank#}4{#/blank#}Yoga, as practiced in the West, is the most widely known and popular of the systems for achieving the necessary state of relaxation. It seems ironical (讽刺性的), though, that as our lives have improved in a material sense we have found it increasingly necessary to go back to forms of activity—{#blank#}5{#/blank#}—which were the natural way of life of our forefathers.

A. be active and practise Yoga

B. There are some aspects of our unhealthy lives that we cannot avoid.

C. and it is especially difficult to do so if you are not good at them

D. physical effort on the one hand and relaxation on the other

E. they spent most of the time out of doors

F. you are still only half way to good health

G. It has to do with deep breathing, emptying your mind of all thoughts, meditation, and so on.

    Self-Care Strategies for College Students

    Most college students don't put self-care at the top of their to do lists. When you're caught up in the whirlwind (旋风) of classes, extra-curricular, work, friendship, and final exams, it's easy to ignore a task that doesn't come with a deadline (even if that task is simply “taking care of yourself”). Embrace the excitement and intensity of college life, but remember that maintaining your physical, mental, and emotional health is essential to your success and well-being. {#blank#}1{#/blank#} Instead, take time out to take care of yourself with some of these self-care strategies.

    Get Away for Some Alone Time. If you live with roommates, privacy can be hard to come by, so make it your mission to find a peaceful place on campus to call your own. {#blank#}2{#/blank#}

    Take a Mindful Walk Around Campus. When you're strolling to class, try this mindfulness exercise to center yourself and destress. {#blank#}3{#/blank#} Feel free to people-watch, but pay attention to sensory details too, like the smell of a nearby barbecue or the sensation of pavement under your shoes. Take note of at least five beautiful or intriguing things you notice along your route. You might find yourself feeling a little calmer by the time you reach your destination.

    Stage a Sleep Intervention. How much sleep do you really get each night? {#blank#}4{#/blank#} By doing that, you'll begin the process of repaying your sleep debt and establishing healthy new sleep habits. Don't buy into the myth that the less you're sleeping, the harder you're working. Your mind and body need consistent sleep to operate at optimum levels – you simply can't do your best work without it.

    Download a New Podcast. Take a break from the books, grab your headphones, and listen to some immersive mysteries, compelling interviews, or laugh-out-loud comedy. There are thousands of podcasts covering almost every subject imaginable, so you're sure to find something that interests you.

A. As you walk, pay close attention to your surroundings.

B. Make a plan to get off campus and explore your surroundings.

C. If you're averaging seven hours or less, commit to sleeping at least eight hours tonight.

D. If you're feeling stressed or overwhelmed, don't punish yourself by pushing your mind and body to their limits.

E. A comfortable corner in the library and even an empty classroom are perfect places to relax and recharge.

F. Actually, it is possible to shorten sleep time by up to 1 hour without the risk of sleep deprivation (剥夺) if you know how to have high quality sleep.
