2、onment?Have you ever thought about trying to help the earth but never really did it?Well,here are some pretty easyand skillful ideas for that green-earth desire inside you.Turn off your computer.By leaving it on all day you are creating more CO2than a regular passenger would,driving to and from work
3、 in one day.Ride your bike or carpool(合用汽车).Obviously,youare creating less CO2which will help the ozone(臭氧).Make a garden.Even simply grow some plants in your kitchen,which will help produce more oxygen whileeating up some of that evil CO2.Buy local groceries.It creates less impact on the environmen
4、t.Besides,youre supporting your localfarmers.Recycle.You had to see this coming.But you have no idea how much you are helping the environment bysimply reusing a water bottle instead of buying a huge pack at the store.Dont run the water while brushing.It saves you money and helps the water resources.
5、Open the curtains.Natural light is much prettier and it will keep the energy usage down.Rechargeable batteries.You have no idea how much it takes to get rid of batteries.Do yourself a favor.Savesome money and some energy.1.If you dont want to create more CO2,you may_.A.turn off your computer or open

8、n than a keyboard does.You can potentially remember more by handwriting,according to a new study.The potential benefits of handwriting for memory have been debated for some time.The new study set outto answer one question:How does handwriting compare to using a keyboard when it comes to remembering
9、newinformation?In all,24 participants took part.Researchers asked each of them to write with a pen and then each was alsoasked to type on a keyboard.While performing these tasks,each volunteer wore a cap that held electrodes next totheir head.It looked somewhat like a hair net fitted with 256 sensor
10、s.Those sensors recorded the participantsbrainwaves.The electrodes noted which parts of the brain turned on during each task.And they showed thatwriting turned on memory areas in the brain while typing didnt.Audrey van der Meer,the new studys leader,says this suggests that when we write by hand,we r
11、ememberbetter.“This is because writing involves complex movements that activate more areas of the brain.The increasedbrain activity gives the brain more hooks to hang your memories on,”she explains.Van der Meer also points outthat writing by hand is related to visual notetaking.“Rather than typing b
12、lindly,the visual notetaker has to thinkabout what is important to write down.Then,key words can be interlinked by boxes,arrows and small drawings,”she adds.This study does not recommend banning digital devices.In fact,its authors point out,computers and otherdevices with keyboards have become neces
13、sary in modern society.Keyboarding can especially benefit those withcertain special needs(such as if they have trouble using their hands)and typing beats writing when it comes tospeed,they add.4.Why were participants asked to wear caps in the study?A.To record their brainwavesB.To inform them of the

17、entify their users monitortheir heart rates and perform other services.Their invention,called HeadFi,is based on a small plug-in headphone adapter that turns a regular headphone intoa sensing device(装置).Unlike smart headphones,regular headphones lack sensors.HeadFi would allow users toavoid having t
18、o buy a new pairof smart headphones with sensors to enjoy sensing features.“HeadFi could turn hundreds of millions of existing,regular headphones worldwide into intelligent ones with asimple upgrade(升级),”said Xiaoran Fan,a HeadFi primary inventor.A Rutgers-led paper on the invention,which results in
19、 earable intelligence,will be formally published in Octoberat MobiCom 2021,the top international conference on mobile computing and mobile and wireless networking.Headphones are among the most popular wearable devices worldwide and they continue to become;moreintelligent as new functions appear,such
20、 as touch-based gesture control,the paper notes.Such functions usuallyrely on aiding sensors,such as accelerometers,gyroscopes and microphones that are availableon many smartheadphones.HeadFi turns the two drivers already inside all headphones into a versatile(多功能的)sensor,and it works byconnecting h
21、eadphones to a pairing device,such as a smartphone.It doesnt require adding aiding sensors andavoids changes to headphone hardware or the need to customize headphones,both of which may increase theirweight and size.By plugging into HeadFi,a converted headphone can perform sensing tasks and play musi
22、c at thesame time.The engineers conducted experiments with 53 volunteers using 54 pairs of headphones with prices ranging from$2.99 to$15,000.HeadFi can achieve 97.2 percent to 99.5 percent accuracy on user identification,96.8 percentto 99.2 percent on heart rate monitoring and 97.7 percent to 99.3
