Although there were 3.4 billion third-party payment accounts(账户)in total in China in 2016, China is not the first country to seek a cashless society. Developed countries like Sweden, Denmark an

9、d Singapore are also seeing that increase. However, the rapid development of cashless payments does not mean there are no challenges and criticisms.

10、gal. Alipay and WeChat Pay, the nations two major third-party mobile payment tools, also launched campaigns this month to encourage more people to use cashless payment methods, which caused concern over whether cash will soon disappear. “Some offline sellers refuse to accept cash, which influences t

16、Artificial intelligence is set to benefit mankind in many ways. It will make everyday tasks easier and bring efficiency to various industries. It might just prove to be one of mans greatest inventions. And yet, like any other technology, AI will also bring risks and dangers. When people mention that

17、 AI could be dangerous, most people think of scenarios from movies or books where an AI program decides to eliminate(消灭)or conquer all humans. In February 2018, a group of AI experts got together to discuss the potential misuse of AI. Their main concern was that criminals could use AI for evil purpo

18、ses. Someone can use AI to create websites that could be used to steal peoples personal information. Another potential risk is faster hacking(非法入侵) AI programs could be taught to find loopholes in software and break into secure computer systems. Some of the risks were as dramatic as the ones we see

19、in books and movies. For example, the experts mentioned automated terrorism (自动化的恐怖主义) by using drones(无人驾驶飞机)or unmanned vehicles as weapons.

They “had” him voice his opinions on the 2017 movie Black Panther and current US President Donald Trump. While in China, the tech giant Baidu, has also

21、 developed a program called Deep Voice that can “copy” anyones voice by analyzing a 3.7-second audio sample.

We simply need to be aware of the dangers, identify them, employ the best possible practice and management, and prep

23、are for its consequences well in advance.” Actually, AI technology is making great progress in terms of the three-stage development of artificial intelligence. It is unlikely that fully developing AI would make it hard for mankind to survive. After all, without human intelligence, AI cannot even dev

24、elop itself, let alone replace human civilization. 5.According to the text, which of the following is NOT the risk brought by AI? A.AI can be used to create websites to steal peoples personal information. B.AI can help criminals to break into secure computer systems without permission. C.AI can be u
