The human beings seem to be facing a crisis （危机）． After Our best Go players were defeated one by one by the artificial intelligence (AI) AlphaGo, we lost our pride of being at the top of the intelligence chain. And in October，when Saudi Arabia gave citizenship to a robot named Sophia, another privilege of being human was take away．It looks like everything that separates humans and AI is at risk fight now．

But we keep hoping that instead of “everything ”, there’s still something left in us that makes us irreplaceable.

To Hao Jingfang, winner of the 2016 Hugo Award for Best Novelette, that “something” is our consciousness. “AlphaGo is intelligent in a certain way, but not intelligent enough to ask the important questions – Do I like playing Co? Do I want to play Go today? Why do I have to play Go when you tell me to?” she once said．In other words, computer programs don’t have a choice to say “no”． They probably don’t even know what a “choice” is – all they ever do is calculate．

And to He Huaihong，a philosophy (哲学) professor at Peking University，imagination and creativity are also what make us special. A machine couldn’t have come up with the theory of gravity just because it was hit by a falling apple，he said．It’s human imagination that connects what seem to be completely random and irrelevant concepts，something that a machine—which works by fixed rules only—can't do，at least for now．

This is why BBC reporter Viktor Mayer-Schonberger suggested that instead of focusing on how computers have overshadowed us on calculating abilities than humans，we should probably “consider our quality at a different end of the spectrum (光谱)：creativity，originality (原创性)，even plain illogical craziness，instead of hard-nosed (顽固的) logic”，he wrote．

So maybe in the future，as artificial intelligence becomes even more intelligent，humans and A1 will learn to use each other’s talents for good．If AI can handle the boring tasks like calculating and driving for us，we’ll have more time to create，think，and be busy with “being human”．

1.What can we learn about AlphaGo，according to Hao Jingfang?

A. It will be taught to say no in the future．

B. It will be more intelligent than humans one day．

C. It has difficulty answering personal questions．

D. It is unable to think independently as humans do．

2.What does He Huaihong believe is unique to humans?

A. Intelligence．　　 B. Originality．

C. The ability to make rules．　　 D. The ability to make choices．

3.What does the underlined word “overshadowed” in paragraph 5 probably mean?

A. Competed with　　 B. Taken control of

C. Been more successful than　　 D. Influenced

4.What could be the future of AI according to the author?

A. It will be used to help humans，rather than compete with us．

B. It may develop creativity besides better logical thinking．

C. It might be very dangerous to humans in different fields．

D. It will be applied to provide driving service for humans．

阅读下面材料，在空白处填入适当的内容（1个单词）或括号内单词的正确形式。

We touch our faces all the time, and it had never seemed to be a big problem – until COVID-19 arrived. 1. (touch) our faces – the “T-zone” of our eyes, nose and mouth in particular – can mean giving ourselves the 2. (dead) virus. This is why 3. (organization) like the Centers for Disease Control and Prevention (CDC) have suggested that we avoid touching our faces. “Just stop this simple behavior,” William Sawyer, founder of Henry the Hand, a nonprofit organization that promotes hand hygiene(卫生), 4.(tell) The Washington Post. “It’s the one behavior 5. would be better than any vaccine ever created.”

Yet, stopping this “simple” behavior might be harder than you think because it’s already hardwired(固有的) into our system. Some face touching is automatic – like when there is 6. itch on your nose, you’ll scratch it without thinking. Moreover, face-touching is subconscious, 7. means it’s very hard to change because you don’t even know you’re doing it. 8.you’re not alone. In a 2015 study, where a group of medical students 9. (film) in class, it was found that they touched their faces an average of 23 times an hour – with 44 percent of the touches being in the “T-zones”. That was particularly surprising since medical students were supposed 10.(know) better. Since it’s so hard to shake the habit, maybe the easiest way is to wash our hands more often. This way, we can be sure that our hands are free from the novel coronavirus.

Exercise seems to be good for the human brain，with many recent studies suggesting that regular exercise improves memory and thinking skills．But an interesting new study asks whether the apparent cognitive benefits from exercise are real or just a placebo effect — that is，if we think we will be “smarter” after exercise，do our brains respond accordingly？The answer has significant implications for any of us hoping to use exercise to keep our minds sharp throughout our lives．

While many studies suggest that exercise may have cognitive benefits，recently some scientists have begun to question whether the apparently beneficial effects of exercise on thinking might be a placebo effect．So researchers at Florida State University in Tallahassee and the University of Illinois at Urbana　　　　 Champaign decided to focus on expectations，on what people anticipate that exercise will do for thinking．If people’s expectations jibe (吻合) closely with the actual benefits，then at least some of those improvements are probably a result of the placebo effect and not of exercise．

For the new study，which was published last month in PLOS One，the researchers recruited 171 people through an online survey system，they asked half of these volunteers to estimate by how much a stretching and toning regimens (拉伸运动) performed three times a week might improve various measures of thinking．The other volunteers were asked the same questions，but about a regular walking program．

In actual experiments，stretching and toning program generally have little if any impact on people’s cognitive skills．Walking，on the other hand，seems to substantially improve thinking ability．

But the survey respondents believed the opposite，estimating that the stretching and toning program would be more beneficial for the mind than walking．The estimates of benefits from walking were lower．

These data，while they do not involve any actual exercise，are good news for people who do exercise．“The results from our study suggest that the benefits of aerobic exercise are not a placebo effect,” said Cary Stothart，a graduate student in cognitive psychology at Florida State University，who led the study．

If expectations had been driving the improvements in cognition seen in studies after exercise，Mr．Stothart said，then people should have expected walking to be more beneficial for thinking than stretching．They didn’t，implying that the changes in the brain and thinking after exercise are physiologically genuine．

The findings are strong enough to suggest that exercise really does change the brain and may，in the process，improve thinking，Mr．Stothart said．That conclusion should encourage scientists to look even more closely into how，at a molecular level，exercise remodels the human brain，he said．It also should encourage the rest of us to move，since the benefits are，it seems，not imaginary，even if they are in our head．

1.Which of the following about the placebo effect is TRUE according to the passage？

A．It occurs during exercise．

B．It has cognitive benefits．

C．It is just a mental reaction．

D．It is a physiological response．

2.Why did the researchers at the two universities conduct the research？

A．To discover the placebo effect in the exercise．

B．To prove the previous studies have a big drawback．

C．To test whether exercise can really improve cognition．

D．To encourage more scientists to get involved in the research．

3.What can we know about the research Cary Stothart and his team carried out？

A．They employed 171 people to take part in the actual exercise．

B．The result of the research removed the recent doubt of some scientists．

C．The participants thought walking had a greater impact on thinking ability．

D．Their conclusion drives scientists to do research on the placebo effect．

4.What might be the best title for the passage？

A．Is it necessary for us to take exercise？
