Imagine you're standing in line to buy an afterschool 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 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. __________67__________ As technology companies move away from traditional password, biometric（生物识别） security, which includes fingerprint, face and voice ID, is becoming increasingly popular.

In 2013, Apple introduced the iPhone 5s, one of the first smartphones with a fingerprint scanner. Since then, using one’s fingerprint to unlock a phone and make mobile payments has become commonplace, bringing convenience to our lives. And since last year, Samsung has featured eye-scanning technology in its top smartphones, while Apple’s new iPhone X can even scan a user’s face.

Nov 3, two brothers showed how they were each able to unlock the same iPhone X using their own face, Quartz reported. 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 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.

“It’s good to see biometrics being used more,” Jain told CBS News, “because it

adds another factor for security. __________70__________”

Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.

It’s a common sight to see food delivery workers riding electric bikes through

big cities in China. Most of them seem to be in a hurry, as they run red lights to deliver their meals in time. However, such reckless（鲁莽的）behavior often causes serious problems.

10

In the first half of this year, food delivery drivers had 76 traffic accidents in Shanghai alone, according to the Shanghai Public Security Bureau. This means that on average, there is a food delivery worker that gets hurt or even dies on the road in Shanghai every 2.5 days.

Other cities also share similar problems. In Nanjing, three people died and 2,473 were injured in road accidents related to food delivery workers in the same period, according to the Ministry of Public Security.

The rise of reckless behavior among food delivery workers is closely related to the growing demand for their service, reported People’s Daily. About 150 million people in China use food delivery services, according to China Radio International (CRI). Such a big market has led to a large demand for food delivery workers, with some companies offering high salaries to attract new workers.

However, food delivery workers are often under high pressure from their employers. They face company fines of 20 yuan for delivering food late and upwards of 200 yuan for receiving complaints, reported CRI. Moreover, the more orders they take, the more commission（佣金）they can earn, leading to some workers checking their mobile phones for new orders while they're riding their bikes.

While most companies have measures requiring delivery workers to follow traffic rules, “there remains a problem of whether these requirements and rules for delivery workers are truly entering their ears, brains and hearts,” Wang Liang, deputy head of the Traffic Police Security Bureau, told news website The Paper.

To solve the problem, some cities have taken action. Shanghai has asked companies to train their workers on traffic rules and safety. Now in Shenzhen, if a delivery worker gets caught breaking traffic rules more than twice, he or she will be banned from driving food delivery vehicles for a whole year.
