26、Imagine you’re standing in line to buy an after-school snack at a store. You step up to the counter (柜台) and the cashier scans your food. Next, you have to pay. But instead of scanning a QR code (二维码) with your smartphone, 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 security (生物识别技术), which includes fingerprint, face and voice ID, is becoming increasingly popular.
But despite its popularity, experts warn that biometrics might not be as safe as we’d imagined.
When introducing the new iPhone’s Face ID feature at Apple’s Keynote Event, Phil Schiller, Apple’s senior vice president, said, “The chance that a random (随机的) person in the population could look at your iPhone X and unlock it with their face is about one in a million.”
But it’s already been done. In a video posted on 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, told CBS News. “No security systems are perfect.”
Earlier this 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 smartphone for police, according to 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 (多种的) security measures is the best defense (保障).”
【1】What’s a major problem of the iPhone X’s Face ID system?
A．It often fails to recognize its owner’s face.
B．Different faces could be used to unlock the same phone.
C．Face data could be used for other purposes.
D．It takes too long to unlock the phone.
【2】What does Anil Jain think of biometric security?
A．It is perfect enough.
B．It has caused much trouble for police.
C．It’s more secure than traditional measures.
D．It should be used with other security measures.
【3】The author wrote this article mainly to ______.
A．describe the popularity of biometrics
B．show how biometrics has changed our lives
C．point out various problems with biometrics
D．discuss the security problems of biometrics
27、My family moved to St.Paul,Minnesota last year, where the average winter temperature is around 10 degrees Fahrenheit. Once summer ended,everyone went inside to play ice hockey. I’d been on the ice only a couple of times when I was much younger. When I’d fallen and broken my wrist during my second lesson, I’d decided never to put on ice skates again.
Ben,the friend I made in the new city, volunteered to teach me to skate. Even though he was very patient, I was so embarrassed by my clumsiness that I began to make up excuses for not skating.
One day I discovered a faster route home. It took me past a large frozen pond.I noticed a woman teaching a young girl to skate. The girl was attempting to jump and spin in the air. Over and over, she pushed off the ground with the toe of her skate. And over and over, she landed hard on the ice.After I had been watching the girl practice for about a week, one afternoon she suddenly lifted off the ground, spun in the air,and landed on her feet!
The next day I bought myself some brand new skates. Every day on the way home l stopped at the pond and wobbled onto the ice, right next to the girl who had landed her jump.As she perfected her twists and tricks, I taught myself to glide and turmn. It was hard being a beginner,and when I felt I had to fight the urge to simply give up.Instead,every time I went down, I just picked myself up and started over again. Soon I was able to keep my balance and skate more confidently.In just a few weeks,I was actually ready to practice the speed skating, fast stops,and quick turns needed for ice hockey. When I was finally ready to show Ben my newfound skating ability, he told me I should join the local hockey league.I tried out and was chosen for a team. By the end of the season, I was part of a winning team.

29、 “Let’s go to grandpa’s room and see if it still smells funny,” said Tommy.
“Last time it smelled like cheese...” replied Lil.
Sure, these lines from “Rugrats”, a cartoon senies that aired in the 1990s, were meant to be funny. But they also may have a basis in real life, relating to the widely held view that the elderly send out a particular and easily recognizable body odor (气味).
The smell has been described as unpleasant, or simply “old person”. In one study, Japanese researchers traced the odor to a chemical compound (化合物) called 2-nonenal. The compound is a byproduct of other chemical breakdowns and sends out a “greasy” or “grassy” odor as the molecules (分子) exit the skin and are released into the air. Researchers discovered that 2-nonenal was the only odor compound whose presence became stronger with age.
In the study, in which 22 people aged between 26 and 75 were asked to wear odor-collecting shirts to bed, researchers analyzed molecules that stuck to the cloth. The amount of 2-nonenal was three times as much in the oldest subjects as it was in the middle-aged group. The youngest members of the study produced the least amount of 2-nonenal. Researchers assume the increase in 2-nonenal may have a lot to do with the breakdown of omega-7 unsaturated fatty acids (不饱和脂肪酸), because these molecules were also present in the shirts worn by the study’s oldest subjects.
Although the biological purpose behind “old person” smell is still unclear, some researchers believe it’s connected to a built-in age-detecting feature possessed by humans and animals. For instance, some animals can distinguish between older and younger animals by smell alone, and some animals are driven to mate with older animals. It’s possible that the capability to tell the smell of older animals meant that long-term survivors were revealed and these survivors had a genetic (基因的) advantage that boosted their chances of survival. In truth, the scent called “old person” smell could be an advertisement for better genetic quality. It gives a whole new meaning to the term “silver fox”.
【1】Why does the author use the lines from Rugrats?
A.To amuse readers. B.To introduce the issue.
C.To recommend a TV series. D.To analyze a phenomenon.
【2】What did the Japanese researchers find in the study?
A.2-nonenal is on the rise with age.
B.Omega-7 gives out a “greasy” or “grassy” odor.
C.The youngest subjects produce the most amount of 2-nonenal.
D.The rise in 2-nonenal has little to do with the breakdown of omega-7.
【3】What is the new meaning given to the term “silver fox”?
A.Old and smelly. B.Greasy and grassy.
C.Better and advantageous. D.Clever and knowledgeable.
【4】What is the purpose of this text?
A.To advocate respecting the elderly.
B.To explain the causes of old people’s body odor.
C.To prove the advantages of “old person” smell.
D.To clarify the biological purpose behind “old person” smell.
