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. 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.

If you dream in color, you’re not alone: the majority of people today claim to have colorful dreams. But it wasn’t always thus. Research conducted in the early part of the last century consistently found that people reported dreaming most often in black and white.
According to Eva Murzyn at the University of Dundee, there are at least two possible explanations for this strange situation.
The first is the methods used in the researches. The early studies tended to use questionnaires(问卷), while more modern studies use dream diaries (filled in upon rising in the morning) or so-called “REM-awakening”, which involves interrupting people’s dream-filled periods of sleep to find out what they were dreaming about. People’s memories of their dreams are likely to be less accurate by using the questionnaire approach and they are more likely to reflect their beliefs about the form dreams generally take in an unclear way.
The second explanation has to do with black and white television and film. It's possible that the sudden increase in black and white film and television during the first half of the last century either affected the form of people’s dreams at that time, or affected their beliefs about the form dreams generally take.
According to Murzyn’s findings, it’s the explanation based on media exposure that carries more weight. She used both questionnaire and diary methods to study the dreams of 30 older (average age 64) and 30 younger people (average age 21).
The methodological technique made no difference to the type of dreams people reported. However, the extremely important thing was that, across both questionnaires and diaries, the older participants (who had had significant early life exposure to black and white media) reported experiencing significantly more black and white dreams over the last ten days than the younger participants (22 per cent vs. 4 per cent).
Another finding was that older participants reported black and white dreams and colorful dreams to be of equal clearness. By contrast, the younger participants reported that the quality of black and white dreams was poorer. This raises the possibility that the younger participants didn’t really have any black and white dreams at all, but were simply regarding poorly remembered dreams as black and white.
1.We learn from the text that ______.
A. people in the first half of the last century never had colorful dreams
B. older people are more likely to have black and white dreams
C. the dreams of younger people are always colorful
D. people today don’t have white and black dreams any more
2.What did Murxyn do to find out the explanations for the colors in people’s dreams?
A. She applied both questionnaire and diary methods to study people’s dreams.
B. She used diary methods to record people’s dreams.
C. She chose 60 people to answer her questions about their dreams.
D. She woke people up to record the colors of their dreams.
3.What does the underlined expression “carry more weight” in paragraph 5 mean?
A. be heavier B. be more powerful C. be more important D. be more useful
4.From Murxyn’s findings we can infer that ______.
A. both older people and younger people could report colorful dreams clearly
B. young people don’t have any black and white dreams in fact
C. the color of a person’s dream is decided by one’s age
D. it is probably the color of media that affects the color of one’s dream
