（2021·广西南宁市·高三一模） In recent years computer scientists have come up with veral different ways of creating fal videos of people using Artificial Intelligence (AI). The 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 urs to put their faces into famous movie scenes. The process lakes about eight conds, 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 conning out of someone's mouth in a video just like you might edit a document on the computer.
It's one thing to swap the faces of famous actors. But what happens if someone puts out a fake video of a politician, for example, making it look like they 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 en and believed it. On the other hand, what happens if a video is actually real, but people don't trust it becau 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 becau this technology has always fallen behind the deepfakes.
1．What can be learnt about deepfakes?
A．They are all made by apps. B．They are improving rapidly.
C．They are mainly ud to joke. D．They'll lo popularity soon.
2．What does paragraph 3 focus on about deepfakes?
豆芽炒鸡蛋A．The anxieties raid by them. B．The results caud by them.
C．The ways of making them. D．The doubts about them.区域发展不平衡
3．What is the author's attitude to developing AI tools to recognize deepfakes?
杠杆的作用A．Optimistic. B．Supportive. C．Disapproving. D．Uncertain.
4．What is the purpo of the text?
A．To recommend new AI tools. B．To explain the importance of AL
C．To describe a technology trend. D．To stress technology revolutions.
【答案】
1．B 2．A 3．D 4．C
【分析】
这是一篇说明文。文章介绍了近年来，科学家想出了几种不同的方法来制作人工智能虚假视频，这些视频通常被称为“换脸”，许多人非常担心这种技术可能会被滥用。
1．推理判断题。由第二段中的“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 urs to put their faces into fa
mous movie scenes. The process lakes about eight conds, requires one picture, and can be done on a mobile phone.”（起初，换脸很复杂。它需要特殊的知识，数百张被伪造者的照片，以及大量的时间。现在简单多了。有网站和应用程序，几乎任何人都可以换脸。最近有一款应用程序问世，用户可以将自己的脸放到著名的电影场景中。这个过程大约需要8秒钟，需要一张图片，而且可以在手机上完成）可知，刚开始的时候，换脸很复杂，要花大量的时间，但最近推出了一款应用程序，只需要8秒，用一张照片，就可以在手机上完成换脸，由这些可知，换脸发展非常迅速。故选B项。

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 en and believed it. On the other hand, what happens if a video is actually real, but people don't trust it becau they're told it's a deepfake?”（交换著名演员的面孔是一回事。但是，如果有人拿出一个政客的假视频，比如说，让它看起来像他们触犯了法律，会发生什么呢？还有一个问题，就是要花多少时间才能弄清楚什么东
西是假的。即使一段视频被证明是假的，也可能为时已晚。数百万人可能已经看到并相信了它。另一方面，如果一个视频是真的，但是人们不相信它，因为他们被告知它是假的，会发生什么？）可知，第三段主要谈了换脸会带来的问题、引发的焦虑。故选A项。
3．推理判断题。由最后一段中的“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 becau this technology has always fallen behind the deepfakes.”（专家们正在努力创造新的人工智能工具来识别伪造的视频。许多人相信人们很快就能打败换脸。然而，就个人而言，这是非常具有挑战性的，因为这项技术一直落后于换脸）可知，作者认为识别伪造的人工智能工具这项技术一直落后于换脸，所以打败换脸非常具有挑战性，由此可知，作者对开发一种新的人工智能系统来识别换脸持不确定的态度。故选D项。
4．推理判断题。第一段引出“换脸”话题，第二段讲“换脸发展非常迅速”，第三段讲“换脸会带来的问题、引发的焦虑”，最后一段讲“作者对开发一种新的人工智能系统来识别换脸持不确定的态度”，全文介绍的是人们利用人工智能进行换脸，几乎达到以假乱真的地步，由此推知，本文的目的是介绍一种技术时尚——换脸技术，故选C项。

（2021·贵州遵义市·） Scientific experts have warned that deadly pandemics(大流行病) are likely to keep happening if action is not taken to protect natural environments. The warning came in a report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, an international expert group that advis governments. The group has more than 130 member states.

The Centers for Dia Control and Prevention has estimated that three out of every four new or emerging infectious dias in people come from animals. Scientists have said COVID-19 probably started in bats and began spreading among humans.
