EcoSwitch: A Computer Gadget That Saves Money Every time you leave your computer running whilst you get on with other tasks, it uses up valuable energy. It might only seem like a few minutes each time, which may lead you to believe that the cost of this amount of energy is not important. __33___ We all know that we should not be careless about our environment and that we should take responsibility for saving as much energy as possible, but this, of course, is easier said than done. Many of us simply forget. ___34__ But there is an easy and effective solution: the EcoSwitch. You don’t need a circuit board connector or an external device lead to connect your computer to the EcoSwitch. You simply plug it into a USB port, and, whenever you leave your computer, just push the bright green button and your computer will go into energy-saving mode. __35___ When you return to your computer, you just push the button again, and your computer will instantly revert to normal operation. The EcoSwitch has an inbuilt device which calculates the amount of energy saved each time the green button is pressed, which is then converted into a sum of money saved in the currency you choose. To select the currency of your choice, you simply scroll down the touchscreen next to the green button, highlight the currency you want and double-click on it. __36___ Different models and makes of computers use different rates of energy, but EcoSwitch estimates that the savings of an average computer user on their electricity costs will be about $50 a year. No one can say that the EcoSwitch is extortionately priced, either. __37___ As it is compatible with all computers, no computer user will tell you off if you decide to give them the EcoSwitch as a present. Who wouldn’t appreciate a present that they will benefit from long into the future? A        The device is so clever that it allows your computer to continue with most tasks whilst in the energy-saving mode, whether it is streaming a video or downloading an app. B But if you added it all together over the years, you would be surprised how much money you are wasting. C        Once in this mode, the computer is switched off and will need to be rebooted to make it function fully. D       For others, switching off the computer or even setting it to sleep is too much annoying. E 　Not only do you get gratification from knowing how much money you have saved, you will also know that you have helped the planet by being more ecological. F 　On the contrary, the manufacturers believe that at $10 it is very reasonable, considering how much valuable energy it saves. G       Eliminating wasted standby power with just a few EcoSwitches around your home will save up to 800 kilograms of carbon dioxide emissions per year. 答案：BDAEF
