Walmart will soon use 360 robot cleaners across a few hundred of its stores. Using maps input by human employees, the AI-powered cleaners will travel in the store with no difficulty, sweeping the floor--just as human employees used to do.

Perhaps the most striking thing about these robot workers is how not-striking they are. Sci-fi movies suggest a future full of human-like robots who appear with their horrible qualities. Now the future is coming into view, and it looks like a giant lie. It's easy to imagine walking past an Auto-C on a shopping trip without even noticing its presence.

AI has already started to become a part of our everyday life. In New Jersey this week, dozens of workers were hospitalized after a robot at an Amazon fulfillment centre accidentally broke a can and enveloped workers in eye-and-lung-damaging gas. Days earlier in California, an auto-piloted Tesla drove a drunk, sleeping driver down a highway, which no doubt did some potential risk to the other drivers on the road. Highway patrol officers figured out on the spot how to stop the AI car.

Of course, industrial accidents and drunk drivers existed well before AI. Tools with the power to release the burden of physical labor—horses, steam machines, self-driving cars—also come with the power to injure. And the presence of AI-powered machines just steps away from us is, for now, still a rare thing for most people.

But the nature of robots’ coming into our daily life lives will make it harder to recognize—or object to—the bigger changes they bring later. Walmart insists that the robot cleaners give employees more time for customer service and other tasks. Critics point out that they could just as easily become an excuse to reduce staff and wages.

1. What is the difference between sci-fi movies and the reality?
A.Now the human-like robots is hard to recognize.
B.Now people don’t go to see the sci-fi movies.
C.Now the human-like robots can tell lies.
D.Now it is easy to ignore the robots.
2. Why were some workers in hospital in New Jersey?
A.They damaged the robot first.
B.The robot caused an accident on purpose.
C.The robot made a mistake by chance.
D.The robot driving them on the highway had an accident.
3. What is the attitude of the author to AI?
A.SupportiveB.ObjectiveC.DoubtfulD.Indifferent
4. What is the main idea of the passage?
A.Artificial intelligence is bringing great effect to our daily life.
B.Walmart will soon use 360 robot cleaners across its stores.
C.We should say no to artificial intelligence.
D.Artificial intelligence is dangerous to our life.

文章大意:本篇是议论文,作者对克隆灭绝物种进行了分析。

【推荐1】We may weep for the dodo, but could and should we bring this lovely bird back from the dead? De-extinction is the science of restoring lost species and it has been in the news for decades.

The story in modern times began in 1990 when Michael Crichton published his science fiction novel Jurassic Park, in which he imagined a world where scientists were able to bring dinosaurs back to life. Crichton imagined that polymerase chain reaction (PCR) technology could be a way to amplify (放大) tiny quantities of dinosaur DNA and thus build a living embryo.

Sadly, biologists soon realized that DNA in fact breaks down super-fast; even after 100 years, DNA from museum skins of dodos was decayed (腐烂) beyond repair. They could be sequenced (测定序列) using massive computational power, but then only with considerable uncertainty. And even if you capture a DNA sequence, there’s still the problem of how you get living cells to read that sequence and express proteins that make the dinosaur or the dodo.

But why would anyone want to see mammoths, or something like them, roaming (漫游) present-day Siberia? Well, they were undoubtedly amazing beasts. As well as hunting them, our distant ancestors painted their likenesses in caves across Europe. Fascinating as they may be, there's some ecological justification for the project too.

It was this diversity of land surface, broken up by heavy limbs and randomly fertilised by faeces (排泄物), that supported so much flora (植物群). Without the mammoths, that diversity disappeared. Return them and landscapes would once again be with a variety of species, including flowers and bushes.

True, it’s not de-extinction in the sense of bringing a long-dead species back to life. Instead it’s more like making a “dodo” by engineering a modern pigeon, its closest relative, to become huge and flightless. The result would be a big, fatty pigeon that, whether it looked like a dodo or not, would probably fulfil some of its ecological roles.

As a palaeontologist, I would of course love to see living dinosaurs, mammoths and dodos. In some ways, though, I am relieved that the optimistic claims for cloning and genetic technologies have not been borne out. The slowdown gives us time to consider the outcomes—and hopefully avoid some of Michael Crichton’s more fevered imaginings.

1. What is paragraph 2 of the text mainly about?
A.A science fiction review.B.The development of DNA.
C.An inspired guess of de-extinction.D.The application of PCR technology.
2. What’s the barrier to cloning a living embryo?
A.DNA is hard to keep for long.B.Computational power is limited.
C.Biologists are opposed to it.D.Living cells can􀆳t be sequenced.
3. Why are people interested in cloning extinct species?
A.They expect to seek hunt fun.B.They lack sources of modern art.
C.They need them for research.D.They want to see biodiversity.
4. What’s the author’s attitude toward cloning extinct species?
A.Cautious.B.Unclear.C.Dismissive.D.Approving.

【推荐2】Just how bad of a mother am I, I silently wondered, as I watched my 13-year-old son deep in conversation with Siri. Gus has autism (自闭症), and Siri, Apple's “intelligent personal assistant” on the iPhone, is currently his BFF(Best Friend Forever). Obsessed with weather formations, Gus had spent the past hour exploring the difference between isolated and scaltered thunderstorms—an hour during which, thank God, I didn't have to discuss with him myself. After a while I heard this:

Gus:“You're a really nice computer.”

Siri:“It's nice to be appreciated.”

Gus:“You're always asking if you can help me.Is there anything you want?” Siri: “Thank you, but I have very few wants.”

Gus: “OK. Well, good night!”

Siri: “See you later!”

That is Siri. She does not let my communicatively impaired son get away with anything. When Gus discovered there was someone who would not only find information for him related to his various obsessions but would also be willing to tirelessly discuss these subjects, he was hooked.

She is also wonderful for someone who does not pick up on social cues: Siri's responses are not entirely predictable, but they are predictably kind—even when Gus is rude. I heard him talking to Siri about music, and Siri offered some suggestions. “I don't like that kind of music.” Gus snapped(厉声说). Siri replied, “You're certainly entitled to your opinion.” Siri's politeness reminded Gus what he owed Siri. “Thank you for that music, though.” Gus said.

My son's practice conversations with Siri are starting to translate into increased facility with actual humans. Yesterday I had the longest ever conversation with him. Admittedly, it was about different species of turtles which might not have been my choice of topic, but it was back and forth, and followed a logic. For most of my son's 13 years of existence, this has not been the case.

Indeed, many of us wanted an imaginary friend when we were young, and now we can all have one not entirely imaginary anytime we wish to. In a world where the commonly held wisdom is that technology isolates us, it's worth considering another side of the story.

The developers of intelligent assistants recognize their potential usefulness for those with speech and communication problems, and some are currently pondering new ways in which the assistants can help. “For example, the assistant would be able to track eye movements and help the autistic learn to look you in the eye while talking." said William Mark, vice president of the company from whom Apple purchased the technology behind Siri. “See, that's the wonderful thing about technology. Getting results requires a lot of repetition. Machines are very, very patient."

1. What did the author feel when she watched her son having a deep conversation with Siri about thunderstorms?
A.Concerned but helpless.B.Excited and overjoyed.
C.Guilty but relievedD.Hopeless and surprised.
2. Which of the following statements about Gus is true?
A.He had always dreamed of having an imaginary friend.
B.He shows no interest in anything that is not related to weather.
C.He has trouble communicating with others because of his illness.
D.He has been friends with Siri since he was diagnosed with autism.
3. Siri has helped Gus in the following aspects except
A.setting a fixed bedtime routine
B.exploring his special interests
C.shaping his logic while talking
D.improving his interaction with people
4. What does the author learn from her son's story?
A.Siri makes people feel much lonely in modern society.
B.Siri sometimes provides better assistance than people.
C.Siri has a better academic performance than the author.
D.Siri is likely to be an effective cure for her son's autism.
5. What can we learn from the last paragraph?
A.Intelligent assistants will be more widely employed in the future.
B.The use of intelligent assistants will likely be limited to autistic people.
C.Machines are more skilled and patient at communication than humans.
D.William Mark was critical of the future development of intelligent assistants.

【推荐3】A trial project by the Montreal Children's Hospital suggested that the use of medical hypnosis(催眠) can reduce pain and anxiety in patients. The project also resulted in a reduction in the amount of medicines used to perform medical-imaging (医学影像) procedures.

“During the examination children don't move. It works perfectly. It's amazing,“ said Johanne   L'Ecuyer, a medical-imaging technologist at the hospital.

The project was inspired by a French team from Rouen University Hospital Centre where examinations are done under hypnosis instead of general anesthesia(麻醉).

A French medical-imaging technologist— also a hypnotist — was invited to train a few members in the medical-imaging department of the children's hospital. In all, 80 examinations were conducted for the project between January and September, 2019, focusing on the imaging procedures that would cause anxiety.

Hypnosis is not a state of sleep: It is rather a modified(改变的) state of consciousness. The technologist will guide the patient to this modified state—an imaginary world that will disassociate itself more and more from the procedure that follows.

“The technologist must build up a story with the patient," Ms. L'Ecuyer said. "The patient is left with the power to choose what he wants to talk about. Do you play sports? Do you like going to the beach? We establish a subject that we will discuss throughout the procedure."

Everything that happens next during the procedure must be related to this story — an injection(注射) becomes the bite of an insect; the heat on the skin becomes the sensation of the sun and a machine that rings becomes a police car passing nearby.

“The important thing is that the technologist associates what is happening outside the patient's body with what the patient sees in his head," Ms. L'Ecuyer said. "It requires creativity on the part of the technologist, imagination, a lot of patience and kindness."

The procedure appealed to the staff a lot when it was introduced in January. It spread like wildfire that someone from France was here to train the technologists,"   Ms. L'Ecuyer said. She added that she had a line of staff at her door wanting to take the training.

1. One of the results produced by the trial project is ________ .
A.a better understanding of children
B.less use of certain medicines
C.new medical-imaging technology
D.an improved reputation of the hospital
2. According to Paragraph 5, hypnosis works by ________.
A.creating a perfect world for patients
B.forcing patients into a state of deep sleep
C.putting patients into an unconscious state
D.leading patients' consciousness away from reality
3. The procedure was received among the staff with ________.
A.uncertaintyB.worry
C.enthusiasmD.criticism
4. What is the passage mainly about?
A.The use of hypnosis in medical-imaging procedures.
B.The standard method of conducting hypnosis.
C.An introduction of medical-imaging technology.
D.An easy way to communicate with patients.
