Let’s lk at tw ld but ppular inventins we use in ur daily life.Band-Aids(创可贴)
The first Band-Aid was made by American Earle Dicksn in 1921. The idea came t him by chance. Dicksn’s wife Jsephine ften cut her fingers in the kitchen. At that time gauze(纱布) and adhesive tape(胶带)didn’t cme tgether. Peple had t cut them t the right size. Dicksn fund they were always t big and sn fell ff. S he put a piece f gauze n the center f a piece f tape. This is hw he made the first Band-Aid.
Later Dicksn’s new inventins became very ppular all arund the wrld.Bubblegum(泡泡糖)
Bubblegum was invented by accident. In 1928, American gum cmpany wrker Walter E. Diemer played arund with new chewing gum recipes. Chewing gum had already been invented mre than half a century befre then. But Diemer fund that the gum he made was easy t blw. He blew a bubble and then saw the pssibilities.

New Glasses Can Transcribe (转录) Speech in Real Time
When Paul Shuttlewrth bught himself a very expensive pair f eyeglasses fr Christmas last year, it was a strange gift. The glasses didn’t imprve his eyesight, weren’t particularly stylish and uncmfrtably pressed dwn n his nse.
But the glasses are an imprtant tl fr him which have helped him talk and jin in cnversatins in ways that he had never been able t befre. These fantastic glasses autmatically (自动地) transcribe the wrds smene is saying and shw the text n his glasses.
Real-time captining (为……配字幕) is nt a ttally new technlgy. Peple wh are deaf r hard f hearing usually use apps such as Otter t transcribe a cnversatin as they’re having it. But having t ping-png between the persn they’re talking with and their phne can be uncmfrtable and tiring. Hwever, having captins in frnt f yur eyes can change the situatin.
Imprvements in speech recgnitin sftware (语音识别软件) have really enabled these technlgical develpments, says Dan Scarfe, CEO f XRAI Glass, a cmpany that makes a speech-prcessing app that can be used with live-captining glasses. “I believe in abut six mnths we’ll have a new killer piece f hardware that yu can surely use fr this. Then it’s just a questin f finding peple wh want t use it,” Dan says.
While live-captining glasses culd be an unbelievably pwerful tl fr millins f peple, they are nt a cmplete slutin. Fr many peple with hearing lss, understanding a friend in a crwded restaurant is a bad dream. Similarly, live-captining sftware struggles t transcribe crrect cnversatin in these spaces. Backgrund nise remains a big prblem that these glasses d nt yet fully slve.
Many peple wh are deaf r hard f hearing are excited by this technlgy, but sme see it as a danger t requests fr sign language interpreters (手语翻译). Captins d nt shw a speaker’s identity, feelings r vice changes; interpreters can give all backgrund infrmatin.

In the past ten years, great prgress has been made in technlgy. It seems like everything has been greatly imprved. But there is ne thing unlike them. It was invented ver 100 years ag but remained unchanged until nw. I’m talking abut a blind walking stick.
The white stick has been used by many blind peple fr a lng time. Hwever, it hasn’t really been imprved, until a blind engineer named Kursat decided t d smething t change that. He hped his inventin wuld help the blind.
He invented a smart stick called the WeWalk. The smart stick uses built-in speakers and different sensrs (传感器) t warn abut pssible dangers. It helps blind peple in navigating (导航) arund their envirnment. It makes their travel much easier. The stick is priced at arund $500. It is less than half the price f mst smart phnes. Mst peple can affrd it. This inventin is ging t change life a lt fr the blind.
Kursat well understands the difficulties that the blind face. That’s because he is blind himself. He decided t put his knwledge f technlgy int inventing smething. It wuld nt nly change his life, but als the life f many thers.
“In these days, we are talking abut flying cars. But the blind have been using just a simple stick. As a blind persn, when I am at the bus stp, I dn’t knw which bus is cming r which stres are arund me. Nw that kind f infrmatin can be prvided by the WeWalk,” he said, “I believe life f the blind will be much easier and safer.”

D yu knw hw the micrwave ven was invented? In the 1940s, Percy Spencer wrked at a cmpany called Raythen. They were making machines fr Wrld War II. One day, when testing a new machine part called a magnetrn (磁控管), Percy nticed smething strange. A chclate bar in his pcket had melted (融化)! Percy wanted t knw why it had melted.
Percy decided t d sme research. He put a glass f water near the magnetrn, and it biled really fast! Then, he tried heating an egg, which explded (爆炸). Percy realized that the micrwaves frm the magnetrn culd ck fd quickly.
Percy and his team started wrking n a new kind f ven that used micrwaves t ck fd. In 1945, they made the first micrwave ven, called the “Radarange.” This first micrwave was bulky, abut five feet tall and weighing ver 700 punds. It was mainly used in restaurants and n ships because it was t expensive fr hme use.
Over the next few years, engineers wrked t make micrwave vens smaller, cheaper, and safer t use at hme. By the 1970s, many families had micrwave vens in their kitchens. They lved hw fast and easy it was t ck fd with them. Micrwave vens culd make fd in minutes, which was much quicker than traditinal vens.

That future is almst here. “I think it’s ging t happen. Definitely (确切地) in ten years…and hpefully much, much faster.” said Sebastian Thrun in 2021. At that time, his yung cmpany Kitty Hawk Crpratin was wrking n develping a Hying car knwn as eVTOL, r Electrnic Vertical Take-Off and Landing vehicle (车辆).
Flying t wrk r schl sunds unbelievable. Nt nly is it fun t fly, but “there wuld never be traffic again, because the sky is very, very large,” says Thrun. He als thinks eVTOL culd be greener than cmmn cars. “We g much faster, we g in a straight line, we fly n less energy,” he says.
S far, thugh, flying cars haven’t taken ff as a prduct. Will their day cme? There are still many prblems t slve. Their high price means mst peple wn’t be able t affrd ne. S sme cmpanies are develping them as air taxis that peple culd pay t ride. The main prblem with flying cars is safety. Accidents in the air are dangerus t bth the passengers and anyne n the grund beneath. T make eVTOLs safer, many develpers are aiming t make themself-flying —n human pilt required.
Anther prblem is space. Mst aircraft need lng runways t take ff and land. Lifting straight up and dwn like a helicpter slves this prblem. But eVTOLs still need special spaces called vertiprts, fr take-ff and landing. Finding places t put these culd be tricky, especially in crwded cities. But maybe sme culd g n tp f buildings.
What d yu think? Wuld yu enjy riding t schl r t visit a friend in a self-flying taxi?
