While there are a few ways to make use of your old smartphone, one of the better ways is to convert into a dash cam (行车记录仪) that you can use on your bicycle. With the camera, you can record your rides, which is especially helpful if you are involved in a crash with another vehicle.

    To use your smartphone as a dash cam on your bike, you will need to make sure it is properly secured to your bike. To do this correctly, you must take two strips of heavy-duty Velcro (a kind of cloth used as fastening) along with two pipe Clamps (管夹) and a flat corner brace (角撑) to properly attach it. You will start by attaching the comer brace to your smartphone.

    Next, attach a Velcro strip to your phoned back. You will put the second strip on the end of the brace comer and cut any extra Velcro off and away from the brace. By using heavy-duty Velcro, you shouldn't have to worry about the camera brace must be attached to the bicycle directly.

    Take two pipe clamps so you can attach the part of the corner brace so the phone can be held up and used. The pipe    clamps must be positioned near the center of the handlebar, which will enable you to get a better picture when videotaping.

    To run a dash cam app on your old phone, you will just need to download a dash cam app onto the old phone. You will then just start the app at any time you head out on the road. There is always the chance of flaws, but you will be giving yourself a way to protect yourself in a friendly, eco-friendly manner that is much less expensive than purchasing a dash cam.

    We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices (装置) well after they go out of style. That's bad news for the environment – and our wallets – as these outdated devices consume much more energy than the newer ones that do the same things.

    To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life – from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use evolved since the early 1990s. Devices were grouped by generation. Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.

    As we accumulated more devices, however, we didn't throw out our old ones."The Living-room television is replaced and gets planted in the kid's room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices-we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TV's with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions(排放) more than doubling during the 1992 to 2007 window.

    So what's the solution(解决方案)?The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tables instead of TVs and desktop computers could cut energy consumption by 44%.

    Not too long ago, a young man asked me a question: how do you make study more fun? You can improve your study habits and make your process more enjoyable. It's a matter of many things.

    Manage your time

    {#blank#}1{#/blank#} All it takes is sitting down with a calendar, and just mapping out everything you need to do and the time you need to do it: projects, tests, part-time work, homework, parties, doctor appointments.

    Set the mood

    First, choose a good study area. {#blank#}2{#/blank#} Your spot may be in your dorm/bedroom or the library. If you prefer to lie on your bed or sit in a corner of the library, develop a study routine that will allow you to focus. Clean spaces are said to improve productivity. To help you focus, turn off your phone! And while you're at it, limit your access to the Internet.

    Make it a game

    Are you the competitive type? Try competing against yourself. {#blank#}3{#/blank#} Or try joining or starting a study group with fiends and take bets on who can get the most right answers when doing homework.

    Take breaks

    In that hour or two you've scheduled for studying, make sure you also give yourself enough breaks. Set a timer-even a short one, like 25 minutes-and work during that time. When the timer goes off, give yourself a few minutes to relax, drink some water, etc. {#blank#}4{#/blank#}

    Reward yourself Sweet treats and other snacks often come to mind as a “reward”, and that might work for you, but it's also probably not a great idea to eat a bag of potato chips after every 25-minute study session. Rewards can be as simple as allowing yourself to watch some interesting videos. {#blank#}5{#/blank#}

A. And we mean a specific, unique spot.

B. it's important to realize and make peace with the fact that studying isn't always going to be “fun”.

C. You can learn how to learn more effectively.

D. Then set another timer and dive back into your studying.

E. Or you can set goals, and then buy yourself something fun when you meet them.

F. Time management may be the secret weapon to succeeding at everything!

G. See if you can improve your reading speed to get yourself under a certain number of pages in five minutes.
