9、ckC.Disaster Online Newsroom D.Red Cross BlogB As data and identity theft becomes more and more common, the market is growing for biometric (生物测量) technologieslike fingerprint scansto keep others out of private e-spaces. At present, these technologies are still expensive, though. Researchers from Ge
10、orgia Tech say that they have come up with a low-cost device(装置) that gets around this problem; a smart keyboard. This smart keyboard precisely measures the cadence (节奏) with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing
11、things like the force of a users typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine peoples identities, and by extension, whether they should be given access to the computer its connected toregardless of whether someone gets the passwo
12、rd right. It also doesnt require a new type of technology that people arent already familiar with. Everybody uses a keyboard and everybody types differently. In a study describing the technology, the researchers had 100 volunteers type the word touch four times using the smart keyboard. Data collect
13、ed from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market
14、in the near future.1.Why do the researchers develop the smart keyboard?A.To reduce pressure on keys.B.To improve accuracy in typing.C.To replace the password system.D.To cut the cost of e-space protection.2.What makes the invention of the smart keyboard possible?A.Computers are much easier to operat
15、e.B.Fingerprint scanning techniques develop fast.C.Typing patterns vary from person to person.D.Data security measures are guaranteed.3.What do the researchers expect of the smart keyboard?A.Itll be environment-friendly.B.Itll reach consumers soon.C.Itll be made of plastics.D.Itll help speed up typi
16、ng.4.Where is this text most likely from?A.A diary.B.A guidebook.C.A novel.D.A magazine.C A few weeks ago, I sat with a California farmer named Dave Ribeiro. I asked him what he wished to know about farmers. He smiled and said, We walk among you. We look like you and talk like you. We have advanced
17、degrees and hobbies, just like you. Take Dave for example: Hes a young man with a degree in music. And if you walk past him in the street, youll never think, There goes a farmer. Is there someone who you picture like Dave when you think of a farmer? Probably not. I think that most people would pictu
18、re a man in his overalls(工装服). I can tell you that it does not represent Dave or any of other farmers I have gotten to know. Not only do we have to throw out our previous impression of farmers, but farming as a whole doesnt look much like what it used to be either. We recently sent a team out to see
19、 what modem fanning looks like, and they found farmers to be completely different from our usual ideas about them and also came across them in some unexpected places. In a parking lot in a neighborhood of Brooklyn, they met a new crop of young farmers who were trying to bring fresh greens closer to
20、eaters in the city by growing them in high-tech indoor vertical (垂直的) farms. In a Florida field under the fight path of an airport, they discovered farmers with university degrees growing plants that might someday fuel our cars. And in a modem farm in California, they observed how farmers were using
21、 technology to take the best possible care of their animals. These farmers all spend their days in very different waysnone of them looks like the previous farmer we have in our mindbut theyre all working in new ways to feed our planet. Not only do we need to change our idea of what farming looks lik
22、e, but we also need to change our view of where solutions can come from. Feeding all of us is going to take all of us working together.1.How does Dave describe todays farmers?A.They often walk in the street.B.They are leading a very busy life.C.They are similar to ordinary people.D.They have little
23、time to make friends.2.How does the author think most people see farmers?A.They usually wear overalls.B.They have interesting hobbies.C.They are skilled at growing crops.D.They know modern farming practices.3.What is the purpose of the team?A.To deepen connections among farmers.B.To study different
24、technologies in farming.C.To find the new developments of modem farming.D.To encourage farmers to use the new farming method.4.What do the farmers mentioned in Paragraph 5 have in common?A.They all work in the city.B.They all use high technology.C.They all do hard physical work.D.They all work with
25、universities.D If youve been joining in chat room conversation, or exchanging e-mail with your e-pals, you have become one of the millions who write in a special short form of English. And youve got a sense of humor about short forms like SOHF (= sense of humor failure) to describe Internet newcomer
26、s who dont understand you. Across the globe, every night teenagers and their elders are talking onlinemany of them all talking at the same time. Its fast: try talking to six people at once. Its brief: three or four words per exchange. It takes wit (风趣), and quick fingers. And it requires tremendous
27、linguistic economy (语言省略). Theres neither time nor space for explanations. Why consume precious key-strokes telling six friends you have to leave for a moment to take care of your little brother when BRB (be right back) will do? Want to enter a conversation? Just type PMFJI (=pardon me for jumping i
28、n). Interested in whom youre talking to? A/S/L, the nearly universal request to know your pals age, sex and location. You may get 15/M/NY as a response from your pal. If something makes you laugh, say youre OTF (=on the floor),or LOL(= laughing out loud), or combine the two into ROTFL (= rolling on
29、the floor laughing). And when its time to get back to work or go to bed, you type GTG(got to go) or TTYL(= talk to you later). People want to write as fast as possible, and they want to get their ideas across as quickly as they can. Capital letters(大写字母) are left in the dust, except when expressing
30、strong feelings, as it takes more time to hold down the Shift key and use capitals. Punctuation(标点)is going, too.1.How do many people talk on the Internet?A.By sending short e-mails.B.By using a peculiar short form of English.C.By using peculiar English words and expressions.D.In a funny way.2.In or
31、der to talk to several people at the same time on the Internet, what should you do?A.You have to speak fast and fluently.B.You should speak with wit and humor.C.You should pay much attention to the use of exact words.D.You have to express your ideas in a brief way.3.If you get 17/F/NY as an answer t
32、o your A/S/L, what does it mean?A.You are talking to a girl who is 17 and lives in New York.B.The person who is talking to you is a l7-foot-tall girl from New York.C.You are talking to 17 girls who are from New York.D.The person on the other end is 17 from New York and he is fine.4.To save time on t
