Keep Shower Doors Spotless Longer

Waterrepelling sprays (such as RainX) aren't just great for your car. Applying a coat to your shower doors will prevent the buildup of mildew(霉菌) and other residue.

Pick Up Glass Fragments Easily

Collecting the larger pieces of a broken glass or dish is usually easy enough, but picking up those tiny slivers and shards can be tricky. One way to do it is to press a slice of soft bread over the area. Just be careful not to cut yourself when you toss the bread in the garbage.

Sweeten Your Yogurt Without Sugar

Flavored yogurts often contain dozens of grams of sugar, but plain yogurt can be pretty blah. Add flavor without many calories with a few drops of vanilla, mint, or almond extract. You can also microwave your favourite into a compote(蜜餞) and, once it's cool, swirl it into the yogurt.

【題目】 Pinocchio may be just a children's fairy tale, but Spanish scientists at the University of Granada recently investigated the so-called 'Pinocchio effect' and found that our noses don't grow when we tell a lie, but actually shrink a bit.

Dr. Emilio Gómez Milán and his team developed a lie detector test that used thermography to tell if people were lying, and found that whenever participants in their research were being untruthful, the temperature of the tips of their noses dropped up to 1.2℃, while the temperature of their forehead increased up to 1.5℃. Scientists also found that drop in temperature at nose level actually caused it to slightly shrink, although the difference is undetected by the human eye.

'One has to think in order to lie, which rises the temperature of the forehead, ' Dr. Gomez Milan explained the findings. 'At the same time we feel anxious, which lowers the temperature of the nose. '

For this study, researchers asked a number of 60 students to perform various tasks while being scanned by thermal imaging technology. One of these tasks involved calling a 3 to 4 minutes call to their parents, partner or a friend and telling a significant lie. Participants had to devise the lie by themselves during the call, and the thermal cameras picked up this 'reverse Pinocchio effect' caused by the fluctuation (起伏) in temperature in the nose and forehead.

Interestingly, the thermal lie doctor picked up the temperature difference in 80 percent of test subjects, which is a better rate of success than that of any modern lie doctor.

'With this method we have achieved to increase accuracy and reduce the occurrence of 'false positives', something that is frequently with other methods such as the polygraph (測謊儀) , ' said Dr. Emilio Gómez Milán, who added that law enforcement interviewers could one day combine other lie detection technology with thermal imaging to achieve better results.

The thermal lie doctor has been the most reliable in the world, 10% more than the popular polygraph.

【1】Why does the author mention 'Pinocchio' at the beginning?

A.To tell a fairy storyB.To warn us not to lie.

C.To introduce a research.D.To inspire us to doubt old beliefs.

【2】According to the research, what might happen if you tell a lie?

A.Your nose gets longer.

B.Your nose becomes smaller.

C.Your temperature gets higher.

D.Your temperature remains stable.

【3】What can we learn about the research?

A.Researchers conduct the study by interviewing.

B.Researchers design difference lies for participants.

C.The thermal lie detector will prove a popular one.

D.The thermal lie doctor may assist law enforcement.

【4】Which might be the best title for the passage?

A.Will lie detectors tell the truth?

B.Will lying make your nose longer?

C.Will lying make your temperature rise?

D.Will thermal imaging technology be reliable?

Speeding Into the Future With Biometrics

Imagine checking in for a flight by simply walking onto the plane. Or buying groceries with a nod of your head, or withdrawing funds from a ATM with a single glance. Thanks to biometric technology - which uses voice, face, fingerprint, or other physical or behavioral characteristic recognition to 【1】 verify an individual's identity -- those scenarios are not far from becoming reality.

Rapid user identification and more intuitive（簡便的）shopping 【2】 are just a couple of the emerging capabilities of biometrics, which is ready to blossom into a $ 59.31 billion global industry by 2025, according to Grand View Research. Whether it's providing better ways to fight fraud or delivering smarter customer service, the biometrics industry is expanding the 【3】 applications of the technology and transforming human interactions across business and government.

Tools that enable voice recognition, iris recognition, and other methods of identification offer faster and more 【4】 ways to access electronic devices or physical locations by creating unique identifiers such as "voice-prints" and "eye-prints" that can't be faked. They also allow users to maintain consistent digital identities wherever they go.

Millions of smart-phone and tablet users already rely on finger-print scanners and facial recognition systems to unlock or manipulate their devices, but more sophisticated solutions are being 【5】 or are in development across a variety of industries.

"The future of business lies in highly intelligent and automated transactions and smart, faultless customer interactions," says Brett Beranek, general manager of security and biometrics at Nuance Communications. "Among today's fastest-growing trends, the 【6】 toward more nautral and personalized exchanges is quickly making biometrics a go-to technology for firms all around the world, including Fortune 500 leaders."

Nuance has been developing its 【7】 biometrics technologies over the past two decades. Its tools go beyond identifying simple characteristics, such as the sound of an individual's voice, to learning speaking, typing, and behavioral patterns and memorizing 【8】 vocabulary. Such capabilities allow the technologies to recognize when someone is trying to impersonate a customer on the phone or during digital transactions, stopping fraud in its tracks.

Nuance's technology is not only capable of identifying who is 【9】 with it, but also what the user is likely looking for, enabling personalized interactions from the moments they begin. This friction-less experience can be a competitive advantage - driving 【10】 and improving customer satisfaction.
