Big data (数据) is a lot of sets of information that are put together so they can be used by a computer program. It can have different kinds of information from many sources (来源), such as information that comes from schools, social media sites, companies, and governments.     2     Another set can have what they like, where they go to school, and how much time they spend on the computer.

    3     The government uses it to understand how many people travel on buses or trains. The information is then used to make bus or train systems better. Companies use big data,too. It helps them understand who buys their products. For example, one company uses weather data to see when people eat the most ice cream.

Big data can be used for good reasons. Some hospitals use big data to predict if a baby who is born too early will get sick. The hospital can then take extra steps to take care of that baby so he or she does not get sick.     4     It can be used to predict which kinds of people are likely to break the law or hurt others, even if they have not done anything wrong.

    5     It is because the computer programs used to look at big data and understand it are written by people. People think a certain way. Because they think a certain way, they build a model of those ideas. These ideas are then used to look at the data. Sometimes, these ideas are helpful for people or businesses. Other times, bad ideas can cause problems for certain groups of people.

【推荐2】Around the world, artificial intelligence(AI，人工智能) has slowly become a part of our everyday lives. One of the biggest usages is facial recognition(FR) technology.

After enabling people to make payments and open bank accounts, FR has now been put to use in the subway of Zhengzhou, Henan province. Introduced in September, FR is useful for passengers who link their online payment systems to the subway’s smartphone app. China Daily reports that other cities in China, including Beijing, are testing a similar system.

However, the use of facial recognition has caused discussions over privacy and financial(金融的) security risks.

According to China Daily, many people feel uncomfortable using facial recognition. They doubt the necessity of using facial details and worry the information could be let out.

Their concerns aren’t unreasonable. In August, a face-changing app called ZAO allowed user to imitate famous people from films and TV series through the use of facial recognition. Fun as it was, users worried that the app was collecting more personal information.

Sometimes people can refuse the app if they don’t want their facial information let out, but sometimes people don’t have a choice.

Zhao Zhanling, a legal researcher at the China University of Political Science and Law, said the growing public concern over facial recognition is understandable. Once this information is let out, it’s hard to take effective measures.

There is no law in China to regulate the use and collection of facial information, Zhao said, suggesting that app operators, public service providers and government should be more careful in preventing free use of the technology.

Gao Zicheng, a lawyer, said the law is a “must” but will require amount of time, because it is difficult to define(定义) what personal data is private information can be disclosed.

【推荐1】请阅读下面短文，从每小题所给的A、B、C三个选项中，选出一个最佳选项。

The COVD-19 has made a big difference to our lives. In many countries, it has also changed the way people greet each other. To help stop the spread of coronavirus (冠状病毒), people are changing their social habits in order to protect themselves. They give up their usual greeting styles and invent safe ways. Let’s take a look.

France is famous for its romantic greeting. They touch each other’s faces and make a kissing sound. But now, this habit may have to stop. A French manner expert gives everyone in France a suggestion that simply looking into a person’s eyes can be enough as a greeting.

Like the French, Italians are also romantic people. When they meet, they always hug or kiss each other. Recently, an Italian grandma made a video to help everyone fight the disease. According to her, if you want to say hello to others, do not hug or kiss. Instead, you can close one of your eyes and give them a wink (眨眼). Isn’t it cute?

It’s a very Australian thing to put your hand out to shake hands. But if you do this, the virus can jump from one person to another. Now the Australian government is asking Australians to take a pat (轻拍) on the back instead of a handshake. But it also has some problems. For example, it’s a bit impolite if you do this to your teacher. What do you think?

Traditionally, people in Iran shake hands to greet with one another. But today, the COVID-19 has made “footshake” a new way of greeting. A video has been popular in Iran, showing three friends meeting-hands in their pockets-tapping their feet against each other as a greeting.

【推荐2】During COVID-19, we wear masks to keep us safe. However, many of us may face a problem we can’t eat when we wear a mask. Now an Israeli company has created a new invention—a mask that we can wear while eating and it keeps us from the virus(病毒).

The mask has a remote-control(遥控的) mouth. You just need to press a button(按钮) to open a hole in the front of the mask so that food can pass through. When you take out your knife or fork, it will close. The company said the mask could protect people from the virus when they eat. It plans to start selling the mask at a price of 6 to 20 yuan higher than that of a common medical mask.

People have different opinions about the mask. Ofir Hameiri, 32, says that it is a must-have because it allows him to eat while staying safe. However, Ron Silberstein, 29, thinks it won’t work when he eats the ice cream. He wouldn’t want to wear it because the mask might get dirty.

What else have people come up with? Some other cool inventions were created during COVID-19. A Chinese company invented a special helmet(头盔). It can check out people with fevers from up to five meters away. At the same time, it can show the person’s name and medical history, and send this information to nearby hospitals.
