In recent years computer scientists have come up with several different ways of creating false videos of people using Artificial Intelligence (AI). These videos are usually called “deepfakes”. Some deepfakes work by putting the face of one person onto a different person in a video. Others work by taking an existing video of a person and changing it so that the person says or does something they didn’t say or do.

At first, creating deepfakes was complex. It required special knowledge, hundreds of pictures of the person who was being faked, and lots of time. Now it’s much simpler. There are websites and apps that allow almost anyone to create deepfakes. An app recently came out which allowed users to put their faces into famous movie scenes. The process takes about eight seconds, requires one picture, and can be done on a mobile phone. One group of computer scientists created a program that allowed them to edit the words coming out of someone’s mouth in a video just like you might edit a document on the computer.

However, the popularity of deepfakes may cause anxieties. It’s one thing to change the faces of famous actors.But what happens if someone puts out a fake video of a politician, for example, making it look like he broke the law? There’s also the problem of the time it takes to figure out that something is fake. Even if a video is proven to be fake, it could be too late.Millions of people might have already seen and believed it.On the other hand, what happens if a video is actually real, but people don’t trust it because they’re told it’s a deepfake?

Many deepfakes are so good that only another AI system can tell that they’re fake. Experts are working hard to create new AI tools that can identify faked videos. Many people are confident that people can defeat deepfakes soon. However, personally, it is very challenging because this technology has always fallen behind the deepfakes.

文章大意:本文是一篇说明文。社交媒体的发展速度惊人,短视频、直播流媒体给人们的生活带来了便利,能够让人们展现自我,带来认同感。但是,社交媒体的兴起也可能产生副作用,我们应该客观地看待它。

【推荐1】In the past decade,the use of social media has grown in a way that no one could have guessed. It has turned some teenagers into celebrities(名人)and turned the famous into the infamous, overnight.

A key feature of social media, however, is its volatility. Trends come and go, disappearing almost as quickly as they appeared. So, what were the key social media trends of 2019?

Short video apps such as TikTok and its Chinese equivalent Douyin, took the world by storm The Telegraph reported that TikTok was ranked 8th on Apple's App Store in April. And Douyin had more than 300 million domestic monthly active users in June, CNBC said.

Why are these short videos-which are rarely longer than a few minutes--so popular? Jiang Yige, a Singapore-based analyst at FengHe Fund Management, has a theory. “Short videos are just right to fill in the little gaps in our busy schedules’," he told CNBC

These videos-apart from being very convenient-are important to teenagers because they allow them to express themselves, according to Teen Vogue

The sense of community that users of short video apps get is another appealing feature. Liza Koshy, a user of the US app Musically who has over 2 million followers, said that she was thrilled when anyone said that her video had “inspired” him. "It's really cool...because I think as short video creators that's what we all expect," she added.

Live streaming is another feature of our social media life that now seems as natural as sunrise It's a pretty neat idea: You can watch anyone, anywhere, live

However, China has taken live streaming to a whole new level. In China, more than 100 million viewers monthly watch a live streaming video. Forbes thought that a number of factors had led to the popularity of live streaming. Among them is viewers' ability to interact while remaining anonymous.

However, the boom in social media may be having side effects too. Fake news is one serious problem it arguably causes. Material shared on these platforms is often not checked for accuracy. The most basic content can be false and can sway users one way or another. We use social media all the time; that doesn't mean that we understand the influence it is having on us. We should be mindful of both the time we spend on it and its impact on our minds

【推荐2】Today companies have branches around the world. More than 11% of the US managers and workers work online either full-time or part-time, and that number is continuing growing. It is believed that it is a waste of time and money to fly around the world for face-to-face meeting. An effective solution to this problem is to use Web meetings.

A large group of presentations, training classes and meetings are done online without losing the   face-to-face   experience.   Web   meetings   are   online   meetings   where   an   organizer   invites attendees(参会人员) to listen to or watch an online presentation by presenters. Besides, Web meetings can be recorded for later use or downloaded for playback.

Presenters can take surveys to study how to hold a successful meeting. Some Web meeting software programs can watch the users’ desktop behavior to see if they become not focused on the presentation and begin working on other documents. If so, the program can tell presenters when the listeners lose their attention, which will help the presenters know which parts of the meeting need improving.

Web meetings can work well because they’re connected by a server(服务器). Companies have two choices when it comes to these servers. They can either buy a special Web meeting server to hold their meetings at high speed, or they can pay for a Web meeting service center every time to let it help connect every attendee, whose speed is always worrying. The choice depends on how frequently the company holds Web meetings and the average number of people attending the meetings.

Web meetings are an excellent example of how technology is changing the way we do business. With all the technologies today, the traditional office might soon be a thing of the past.

1. What is the advantage of Web meetings?
A.They leave more people unemployed.

D.They make people spend more time on computer.

文章大意:这是一篇新闻报道。文章主要讲述因为用户投诉未能保护好他们的隐私权,Facebook将在未来几周内结束自动识别图片和视频用户的面部识别系统。

【推荐3】Facebook says it is ending its facial recognition system that automatically identifies users in pictures and videos in the coming weeks. The company’s vice president of Artificial Intelligence, Jerome Pesenti, announced the change this week in a statement on the company’s website.

The move comes as the social media service faces accusations that it failed to take action to protect users even though its own research suggested its products can be harmful. In the past, Facebook also faced widespread criticism for not doing enough to protect the privacy (隐私) of its users.

“This change will represent one of the largest shifts in facial recognition usage in the technology’s history,” Pesenti said in his statement. As a result, “more than a billion people’s individual facial recognition templates (模板)” will be removed, the statement added. Facebook has said that more than a third of Facebook’s daily active users have given their permission to have their faces recognized by the social network’s system. That represents about 640 million people worldwide.

Facebook first started offering facial recognition about 10 years ago. But over time, it has made it easier for users to opt out of the system as it faced more pressure from courts and government officials.

Pesenti said the company still sees facial recognition technology as a powerful tool. But he noted that the situations where it can be helpful “need to be weighed against growing concerns about this technology as a whole.” He said examples of acceptable uses of the technology would be to confirm a person’s identity or prevent fraudulent (欺骗的) activities. He added that Facebook will continue working on facial recognition for such uses and will seek out the opinions of outside experts before deciding on how it will use the technology in the future.

Kristen Martin is a professor of technology ethics (伦理学) at the University of Notre Dame in Indiana. She said that Facebook’s decision to shut down the system “is a good example of trying to make product decisions that are good for the users and the company”. She added that the move also proves the power of public and regulatory pressure, since the facial recognition system has long been the subject of strong criticism.

1. Why does Facebook face a lot of accusations?
A.It may restrict users’ access to ii.B.It can reveal users’ false identities.
C.It fails to protect its users’ privacy.D.It refuses to provide help for users.
2. What does the underlined part “opt out of” in Paragraph 4 probably mean?
A.Withdraw from.B.Suffer fromC.Compete in.D.Engage in.
3. What does Jerome Pesenti think of facial recognition technology?
A.It gets away from public pressure.B.It should be closed on social media
C.It wins the strong support of the public.D.It is useful but needs to be improved.
4. What is Kristen Martin’s attitude towards Facebook’s decision?
A.Doubtful.B.Positive.C.Negative.D.Indifferent.
