You’re standing in the dairy section at the grocery store, searching for your favorite brand. Suddenly, you catch a smell of chocolate cookies. You forget about dairy and head for the bakery (烘烤食品) section. Guess what? You just walked into an odor (气味) trap (陷阱)! The odor was cooked up by scientists in a lab.
For years, scientists have been studying the special powers of smell. They found that more than our other senses, smell changes our mood and helps us remember things.
So companies have begun spending thousands of dollars to scent (使充满香味) entire stores. Artificial (人造的) scents are being used to lead customers by the nose. These smells help to get people inside and put them in the mood to buy. They even make customers remember the store later, so they’ll come back for more. Also, many companies have smartly made use of product smells. A company added lemon fragrance to its dish cleaner. They wanted people to think the soap contained “natural” cleaners. It worked!
New uses for smells are being created every day. One bank, for example, gives customers coupons (优惠券) advertising car loans (贷款). To get people to take out a loan, bank officials hope to coat these coupons with the fresh leather smell of a new car. In Australia, telephone offices are putting sweat odor on unpaid bills. Since some people sweat when they’re scared, this smell might remind them of when they were frightened. And they’ll pay the bills right away!
What lies ahead for our noses? Smell scientists are working on some pretty far-out ideas. Would you believe TV sets that produce smells? Or how about scent diets? Certain food smells will fool your stomach into thinking it’s full. Alarm clocks will scent your bedroom with a strong pleasant smell designed to wake you up. Scientists are even working on ways to keep garbage from smelling. Researchers expect scents to help students make more sense of what they’re learning.
And just think. Someday soon, even your homework may smell nice!

3.What does the author mean by saying “Someday soon, even your homework may smell nice!”?
A.Students would benefit more from smell research. |
B.Students would be more willing to do homework. |
C.Smell research would develop beyond our imagination. |

If you happen to find “On the Road” at a gas station or “Who Moved My Cheese?” in your grocery store, it might not be and accident. You could be the unwitting beneficiary of a “bookcrosser”---- a person who on purpose leaves books in public places hoping they’ll be found by strangers.
The idea o leaving a book for someone else to find and enjoy is not new ---- some people have been leaving just-finished books in airports and on buses since the dawn of the hurry-up-and-wait. Creating a system for book-leavers to find out what happened to those books adds a new way to the practice. Bokcrossing.com, the website that encourages books to be “released into the wild”, has more than 18,000 members since its start last year, and averages 112 new participants daily.
Its members have scattered(分发) more than 42,000 novels, self-help books, memoirs, technical manuals and biographies in 45 countries, leaving them in public restrooms, movie theatres, coffee studios or anywhere that they can imagine. The result: a worldwide living library.
Peri Doslu, a California yoga instructor, has dropped three--- one on top of a telephone booth, one on a rock wall at remote Mono Lake in the eastern Sierra Nevada, and another in one of the studios where she teaches.
“I’m always looking for paces to pass on books,” said Doslu. “To think my book’s going to go off and have this future, and I might even get to know a little bit about it down the road.”

Imagine you’re standing in line to buy a snack at a store. You step up to the counter and the cashier scans your food. Next, you have to pay. But instead of scanning a QR Code(二维码) with your smart phone, you just hold out your hand so the cashier can scan your fingerprint. Or, a camera scans your face, your eyes or even your ear.
Now, this type of technology might not be far away. As technology companies move away from the traditional password, biometric (生物特征识别的) security, which includes fingerprint, face and voice ID, is becoming increasingly popular.
In 2013, Apple introduced the iPhone 5s, one of the first smart phones with a fingerprint scanner. Since then, using one's fingerprint to unlock a phone and make mobile payments has become a commonplace, bringing convenience to our lives. And since 2016, Samsung has featured eye-scanning technology in its top smart phones, while Apple's new iphone X can even scan a user's face. But despite its popularity, experts warn that biometrics might not be as secure as we imagine. " Biometrics is ideally good in practice, not so much," said John Michener, a biometrics expert.
When introducing the new iPhone's face ID feature, Phil Schiller, Apple's senior vice-president, said. "The chance that a random person in the population could look at your iPhones X and unlock it with their face is about one in a million." But it's already been done. In a video posted on a community website Reddit, two brothers showed how they were each able to unlock the same iPhone X using their own face. And they aren't even twins.
"We may expect too much from biometrics," Anil Jain, a computer science professor at Michigan State University, told CBS News. "No security systems are perfect."
Earlier last year, Jain found a way to trick biometric security. Using a printed copy of a thumbprint, she was able to unlock a dead person's smart phone for the police, according to a tech website Splinter. "It's good to see biometrics being used more," Jain told CBS News, "because it adds another factor for security. But using multiple security measures is the best defense."
1.Which is the latest identification technology in a smart phone according to the passage?
A. Face scanning. B. Eye scanning.
C. QR Code scanning. D. Fingerprint scanning.
2.What is a major problem of the iPhone X's face ID system?
A. It takes too long to unlock the phone.
B. It often fails to recognize its owner's face.
C. Face data can be used for other purposes.
D. Different faces can be used to unlock the same phone.
3.What is Anil Jain's opinion about biometric security?
A. It is as secure as traditional measures.
B. It is perfect without much improvement.
C. It has caused much trouble for the police.
D. It should be used with other security measures.
4.What does the author intend to tell us in this passage?
A. The popularity of biometrics.
B. Security problems of biometrics.
C. Various problems with biometrics.
D. Great changes caused by biometrics.

When you’re shopping at the grocery store, you probably expect that the olive oil you see came from,well, olives. And that the organic vegetables were never exposed to poisonous chemicals. Increasingly, however, there’s a chance you might be ______. In recent years, there has been a rise in reports of so-called food fraud, or attempts by various entities — including storage workers, suppliers and distributors — to alter products and mislead customers and food companies alike for ______ gain. Among the more recent examples: “natural” honey containing antibiotics and Italian companies selling “Italian olive oil” from a blend of oils that did not ______ from Italy.
By and large, the fraudsters are trying to make easy money — ______ for a whole food or pricey ingredient, then cutting it with ______ stuff secretly. But the health consequences can be ______.
How can this happen? In the U.S., the Pure Food and Drug Act has prevented the “manufacture, sale or transportation of misbranded or poisonous foods” since 1906, and similar laws exist in other countries.
But most global food regulators, including the U.S. Food and Drug Administration, aren’t ______ to enforce them effectively. For the most part, they focus on safety standards — ______ that foods don’t contain bacteria or viruses — and rely on companies to police their own ingredients, lest they face ______ backlash(强烈抵制). But now that food manufacturing has become globalized, supply chains are longer, creating more opportunities for bad actors to ______. Anyone who can ______ substituting cheap ingredients for more expensive ones is going to try.
Governments are starting to fight back. In 2014, the U.K. created a food-crime unit that collects reports of food fraud. But in order to prevent fraud in the first place, the food industry needs to ______ the safeguarding of its own production network. So the Global Food Safety Initiative (GFSI) — a trade group including officials from more than 300 food manufactures — will this year start ______ its members’ supply chains, from field to table, to identify vulnerabilities.
______, dozens of other food-industry experts recently teamed up with academics from Michigan State University to launch the Food Fraud Initiative (FFI), a group that studies fraudsters — specifically, how they avoid safeguards — and then advises food companies on how to get rid of them. “There are plenty of criminals out there who are going to wake up and perceive some opportunity for fraud,” says John Spink, director of the FFI. “We just need to make ourselves a(n) ______ target.”
1.A.definite B.peaceful C.optimistic D.wrong
2.A.financial B.social C.technological D.potential

高三英语短对话中等难度题查看答案及解析
Would you give your Social Security Number to the clerk at the grocery store? Of course not, right? Yet, if you’re like most people, you wouldn’t hesitate to give out a different, but equally important number to the same person.
Experts now say that your cellphone number may be more pivotal than any other personal information in the eyes of spammers (垃圾邮件发送者) and identity thieves. In other words, instead of handing it out, you should guard that cellphone number with your life.
Today, your cellphone number will likely be with you for a very long time. That means if spammers get your cellphone number, it will be much harder to get rid of them. It also means that over the years, your cellphone number will be linked to a lot of personal information—from contact lists(通讯录) to bank card numbers, all information that hackers(黑客)would love to get their hands on.
A few years ago, German security researcher Karsten Nohl showed what he could obtain using only a person’s cellphone number. California Congressman Ted Lieu was given a new cellphone for a day and Nohl was given that cellphone number. Using just that number, Nohl was able to find Lieu’s location and movements throughout Los Angeles, read his emails and text messages, and record phone calls between Lieu and his staff. And Nohl did all of this from his office in Berlin using just a cellphone number.
Still think it’s a good idea to post your number on a noticeboard?
It’s safe to assume that Nohl is an expert when it comes to hacking, but even the ordinary thief can use your cellphone number to cause harm to you. When you sign up for an account online, you usually provide your email address and a password (密码). But if you forget that password, many of these companies will send you a password retrieval code (检码)via your cellphone. Let’s say you post something for sale online and you include your name, email, and cellphone number. You’ve now given a potential thief everything he needs to hack into any of your online accounts. Therefore, it just makes sense to protect yourself by guarding that number as closely as you would guard any other personal information.
1.What does the underlined word “pivotal” in Paragraph 2 most probably mean?
A.Accessible. B.Familiar.
C.Important. D.Manageable.
2.What does the third paragraph mainly talk about?
A.Why people should protect their cellphone numbers.
B.Why people seldom change their cellphone numbers.
C.How to protect our personal information.
D.How to get rid of spammers.
3.What did Karsten Nohl’s show intend to prove?
A.Nohl is a real expert in hacking.
B.It’s necessary to fight against hackers.
C.Lieu’s new cellphone has powerful functions.
D.It’s easy to hack information via cellphone numbers.
4.What can we infer from the last paragraph?
A.It’s a good idea to sell something online.
B.It’s necessary to register several accounts online.
C.It’s common for people to forget their passwords.
D.It’s risky to post your cellphone number online.
