Vehicles ften cme int cnflict with ther vehicles and pedestrians when their intended curses f travel intersect (交叉), and end up being in each ther's way. The general principle that establishes wh has the right t g first is called “right f way”， r “pririty”. It determines wh has the right t use the cnflicting part f the rad and wh has t wait. Signs, signals, markings and ther features are ften used t make pririty clear.
A driver must yield (让行) the right f way t ther drivers：
●When appraching a YIELD sign. Slw dwn r stp t avid a crash.
●Even after the light turns green when there are vehicles in the intersectin.
●When appraching emergency vehicles using sunding r flashing sirens.
●After cming t a cmplete stp at an intersectin where there is a stp sign r a flashing red signal. If there is n stp line, stp befre the crsswalk.
●When making a left turn n a red light after a stp frm a neway street t anther neway street with traffic mving t the left. (See Figure A．)
●When tw vehicles n different radways arrive at a furway stp intersectin at the same time, the vehicle shuld yield t the vehicle n its right. (See Figure B．)
●When cming ut f an alley, building, private rad r driveway after cming t a cmplete stp. (See Figure C．)
●When crssing traffic at the end f a “T” rad with n traffic cntrl signs r signals. (See Figure D．)
eq \x(语篇解读：当车辆和其他车辆、行人的行驶路线发生交叉时，往往会与其发生冲突。为了避免这样的冲突，本文给驾驶员们简单介绍了几种情况下优先通行权的归属方。)

What d yu d when nbdy is arund t take yur picture? Yu take a selfie (自拍照). But what abut selfies in space? On Twitter last year, NASA astrnaut Edwin “Buzz” Aldrin, wh famusly became the secnd man t walk n the mn in July 1969, laid claim t a spaceflight first: taking the first selfie in space during the Gemini Ⅻ missin in 1966.
“Fr me, it needs t be digital t be a selfie，” argues Jennifer Levasseur, wh is in charge f the Smithsnian Natinal Air and Space Museum. Accrding t Levasseur, the cncept f a selfie is directly linked t Internet culture and the human desire t interact (互动) n scial platfrms. “The thing that makes a selfie is sharing it，” she says.
Still, astrnauts have been carrying cameras abard space vehicles since the 1960s, and they've taken plenty f pictures f themselves alng the way. Astrnauts had t pull the film magazines ut and leave their cameras behind when they returned t Earth, because early space missins were restricted by a cnservative weight limit n the return trip.
A big change in space camera technlgy came after the sad lss f the space shuttle Clumbia, which brke apart n its return t Earth in 2003. “Fearing that they wuld never be able t bring the film back frm space and lse all that hard wrk accelerated the push fr digital，” Levasseur says.
Tday, astrnauts can have access t the Internet and scial platfrms in space and pst true space selfies taken by digital cameras. Taking selfies and sharing them n scial media is a way that astrnauts in space can participate in the same activities peple n Earth d every day. The first astrnaut selfie that went viral (疯狂传播) n the Internet was ne by Japanese astrnaut Akihik Hshide in 2012.
eq \x(语篇解读：本文是一篇说明文。文章介绍了在太空中自拍的历史。)
4．What des Levasseur think f Aldrin's claim?
A．It hardly makes any sense.
B．It revlutinizes astrnautics.
C．It cntradicts public pinins.
D．It needs t be further prved.
解析：选A 推理判断题。根据第一段中的“Edwin ‘Buzz’ Aldrin ... laid claim t a spaceflight first: taking the first selfie in space”以及第二段内容可知，Aldrin声称自己是太空自拍第一人，但是Levasseur认为数码自拍照才算自拍照，自拍照最重要的就是能分享到网上。由此可推知，Levasseur认为Aldrin的话说不通。
5．Why were cameras left in space n early space missins?
A．T lighten the lad f the spaceship.
B．T test cameras under extreme cnditins.
C．T prepare fr the next stage f space explratin.
D．T take mre pictures in space by remte cntrl.
解析：选A 细节理解题。根据第三段最后一句可知，宇航员返回地球时要把相机丢下，因为早期的太空任务在返回时有重量限制。
6．What advanced space camera technlgy?
A．The inventin f new films.
B．The fear f falling behind in the space race.
C．The cncern abut the lss f valuable data.
D．The ppularity f space selfies n scial media.
解析：选C 细节理解题。根据第四段内容可知，“哥伦比亚”号航天飞机失事使人们开始担忧无法把胶卷带回地球，这样所有的努力就都白费了，由此加快了在太空探索时使用数码相机的步伐。
7．What is the best title fr the text?
A．The Explratin f Space
B．The Histry f Selfies in Space
C．The Change in Space Camera Technlgy
D．The Develpment in Space Technlgy

(2021·长沙模拟)Tw deer jumped ut in frnt f 16yearld Amanda Flyd's car. She put n the brake, stpping the car just in time. But later, she started texting. Distracted, Amanda turned left and right, then crashed int anther car. Luckily, she wasn't in a real car — she was in a driving simulatr (模拟器) at Rsevelt High Schl, Ohi, US. “I never really realized that cars make a turn that much，” Amanda, a junir, said. She added that she wuldn't text while driving anymre.
The Ohi Department f Transprtatin (ODOT) and Ohi State Highway Patrl brught the simulatr t the schl. They said they wanted t help students learn abut the danger f driving while drunk, texting, r talking n the phne.
Accrding t the Natinal Highway Traffic Safety Administratin, distracted driving claimed 3,450 lives in 2016 alne. Experts believe the actual figure is prbably higher.
The simulatr is basically a cmputer prgram. Like many cmputer games, it was a hit with the students. They lined up and crwded arund t watch each ther take turns. The simulatr has a steering wheel (方向盘), brake and gas pedal (油门). It is made up f three large cmputer screens n a table.
Students chse a distractin, such as driving while drunk r texting. They always crash, f curse. Then, they are pulled ver by the plice t be taught the bad results f their driving: hw much damage they've caused, what their fine is, if anyne died in the accident, and if they're ging t g t prisn.
“It teaches hw t drive withut being n the rad，” said Shante Thmpsn, 16. She had just crashed int a deer.
ODOT spkesman Justin Chesnic said hundreds f kids have gne behind the wheel s far. He said even mre have benefited frm watching their classmates.
“Driving is such a majr respnsibility, s take it seriusly，” he said. “Put away yur cellphne. A lt f the accidents ut there are because f distracted driving. It can nt nly change yur life, but change smene else's life frever. The results are serius.”

In a wrld where nearly 6 millin fingerprint recrds f gvernment emplyees are stlen in ne cmputer hack (非法侵入), and here millins f peple are victims f identity theft every year, the next step in cyber security may well be mapping yur brain.
Researchers at Binghamtn University, State University f New Yrk are wrking n a bimetric (生物特征识别的) system that recrds hw yur brain reacts t certain images. With a little mre plishing, the scientists' brainchild culd becme the way yu get int a safe depsit bx, yur ffice r past scanners at the airprt. It culd replace the passwrd fr yur nline banking, yur email r yur scial media accunts.
They started their prject by measuring the brain waves f 30 subjects. The subjects were fitted with a cap that had 30 electrdes (电极) attached t it, and then shwn varius images and symbls — celebrity faces, wrds, pictures f fd — n a cmputer screen in 200millisecnd bursts. The brain's reactin was recrded.
The idea is that every time a persn needs t use a “passwrd”， he r she ges thrugh the same prcedure, and the results are matched with their firsttime reactin. If the “brainprint” is cmprmised — like what happened with the fingerprint recrds — then the system is merely reset by running anther set f images and cllecting a different set f brain waves. “Even if that was stlen, yu culd just cancel it and recrd ne t smething else”， says prfessr Laszl.
Laszl and her team have shwn that their system can be 100 percent accurate. S ne f the mre difficult parts f making the system practical already has been vercme. Nw, they're spending much time recrding accurate brainprints with as few as three electrdes, which culd make recrding in the future as easy as wearing a pair f special glasses. They're als wrking with cheaper materials and different methds t see if they can bring the cst dwn.
