9、 that bill,”Mangano says.But she had a special ability for seeing the obvious thing.She knew how hard it was to mop the floor.“I was tired,of bending down,putting my hands in dirty water,wringing(拧)out a mop,”Mangano says.“So,Theres gotta be a better way.”How about a“self-wringing”mop?She designed a

10、 special tool you could twist in two directions at once,and still keep your hands clean and dry.She set out to sell it,first a few at flea markets.Then Mangano met with the media.But would couch potatoes(电视迷)buy a mop?The experts on shopping TV were less than certain.They gave it a try,and it failed

11、 Mangano was sure it would sell if theyd let her do the on-camera display.She said,“Get me on that stage,and I will sell this mop because its a great item.”So QVC,a multinational corporation specializing in televised home shopping,took a chance on her.“I got onstage and the phones went crazy.We sold

15、a week to support her family.C While the start of a new school year is always exciting,this year was even more so for some elementary school students inAuckland,New Zealand.They became the worlds first kids to be“taught”by a digital teacher.Before you start imagining a human-like robot walking aroun

16、d the classroom,Will is just an avatar that appears on the students desktop,or smartphone screen,when ordered to come.The autonomous animation platform has been modeled after the human brain and nervous system,allowing it to show human-like behavior.The digital teacher is assigned to teach Vectors“B

17、e sustainable with energy”a free program forAucklandelementary schools.Just like the humans it replaced,Will is able to instantly react to the students responses to the topic.Thanks to a webcam and microphone,the avatar not only responds to questions the kids may have,but also picks up non-verbal cu

18、es.For instance,if a student smiles at Will,he responds by smiling back.This two-way interaction not only helps attract the students attention,but also allows the programs developers to monitor their engagement,and make changes if needed.Nikhil Ravishankar believes that Will-like avatars could be a

23、s First Digital Teacher,a Help to Students D.New ZealandWill Replace Teachers in Classrooms D This year researchers expect the world to snap 1.35 trillion photographs,or about 3.7 billion per day.All those pixels(像素)take up a lot of room if they are stored on personal computers or s phones,which is

24、one reason why many people store their images in the cloud.But unlike a hard on drive which can be encrypted to protect its data,cloud storage users have to trust that a tech platform will keep their private pictures safe.Now a team of Columbia University computer scientists has developed a tool to

25、encrypt(加密)images stored on many popular cloud services while allowing authorized users to browse and display their photographs as usual.Malicious(恶意的)attempts to access or leak cloud-based photographs can expose personal information.In November 2019,for example,a bug in the popular photograph stora

29、g these three files(allowing a block from the red file,for instance,to hide out in the green or blue ones).But the program does nothing within the pixel blocks,where all the image processing happens.As a result,the files remain unchanged images but end up looking like grainy black-and-white ones to

31、by experts?A.They sell users passwords.B.They have invented new tools.C.They often let out personal information.D.They may steal a glance at users images.14.Whats the advantage of ESP?A.It can provide clear images.B.It can decrease the upload time.C.It can classify images automatically.D.It can encr
