Artificial intelligence can predict when patients with a heart disorder will die, according to scientists.
The software learned to analyze blood tests and scans of beating hearts to spot signs that the organ was about to fail. The team, from the UK’s Medical Research Council, said the technology could save lives by finding patients that need more aggressive treatment. The results were published in the Journal of Radiology.
According to the researchers, high blood pressure in the lungs damages part of the heart, and about a third of patients die within five years after being diagnosed. There are treatments: drugs, injections straight into the blood vessels, a lung transplant. But doctors need to have an idea of how long patients might have left, in order to pick the right treatment.
The software was given scans of 256 patients’ hearts, and blood test results. When this data was combined with eight years of patient health records, the artificial intelligence predicted when patients would die.
The software could look about five years into the future. It correctly predicted those who would still be alive after one year about 80% of the time. The figure for doctors is 60%.
The team now want to test the software works in other patients in different hospitals before assessing whether it should be made widely available to doctors. The researchers also want to use the technology in other forms of heart failure, such as cardiomyopathy, to see who might need a pacemaker or other forms of treatment.
Dr Mike Knapton, from the British Heart Foundation, said, “This exciting use of computer software in medical practice will help doctors in the future to make sure that patients are receiving the correct treatment before the condition deteriorates and leaves them needing a lung transplant. The next step is to test this technology in more hospitals with heart disease.”

Artificial intelligence can ide ntify skin cancer in photographs with the same accuracy as trained doctors, say scientists. The Stanford University team said the findings were "incredibly exciting" and would now be tested in clinics. Eventually, they believe using AI could revolutionize healthcare by turning anyone’s smart-phone into a cancer scanner.
The AI was repurposed from software developed by Google that had learned to spot the difference between images of cats and dogs. It was shown 129,450 photographs and told what type of skin condition it was looking at in each one.
It then learned to spot the hallmarks of the most common type of skin cancer: carcinoma, and the most deadly: melanoma(黑色素瘤). Only one in 20 skin cancers are melanoma, yet the tumor(肿瘤) accounts for three-quarters of skin cancer deaths.
The experiment, detailed in the journal Nature, then tested the AI against 21 trained skin cancer doctors. One of the researchers, Dr Andre Esteva, told the BBC News website: "We find excitedly, in general, that we are on par with excellent skin cancer doctors."
However, the computer software cannot make a full diagnosis, as this is normally confirmed with a tissue biopsy(活检). Dr Esteva said the system now needed to be tested alongside doctors in the clinic. "The application of AI to healthcare is, we believe, an incredibly exciting area of research that can be leveraged to achieve a great deal of societal good," he said. "One particular route that we find exciting is the use of this algorithm on a mobile device, but to achieve this we would have to build an app and test its accuracy directly from a mobile device." Incredible advances in machine-learning have already led to AI beating one of humanity's best Go players.
And a team of doctors in London have trained AI to predict when the heart will fail.
1.From the passage we can infer that ________.
A. Artificial Intelligence must replace human one day
B. we can use Artificial Intelligence to cure skin cancers
C. we can use smart-phone to scan our skin at present
D. the research will be of great help to us and our health care
2.Which one will he agree with according to Dr Esteva?
A. Artificial Intelligence has beaten all of humanity’s best Go players.
B. Artificial Intelligence could support assessments by GPs.
C. We still need professional doctors with the help of the system.
D. There are too many disadvantages for Artificial Intelligence.
3.The underlined words “on par with” in Para 4 likely mean ________.
A. inferior to B. equaled by C. superior to D. opposite to
4.What’s probably the best title of this passage?
A. Cancer Doctors Are Out
B. An APP Scanning Skin Cancers
C. Artificial Intelligence—change our future
D. Artificial Intelligence—as good as cancer doctors

An artificial intelligence can accurately translate thoughts into sentences, at least for a limited vocabulary of 250 words. The system may bring us a step closer to _______ speech to people who have lost the ability.
Joseph Makin at the University of California, San Francisco, and his colleagues used deep learning algorithms(算法) to study the brain _______ of four women as they spoke. The women, who all suffer from a certain kind of brain disorder, already had electrodes attached to their brains to monitor disease attacks.
Each woman was asked to read aloud from a set of sentences as the team _______ brain activity. The largest group of sentences _______ 250 unique words. The team fed this brain activity to a network algorithm related to nerves, training it to _______ regularly occurring patterns that could be linked to repeated aspects of speech. These patterns were then fed to a second network, which tried to turn them into words to _________ a sentence.
Each woman repeated the sentences at least twice, and the final repetition didn’t form part of the training data, _______ the researchers to test the system.Each time a person speaks the same sentence, the brain activity associated will be similar but not exactly the same. “Memorizing the brain activity of these sentences wouldn’t help, _______ the network instead has to learn what’s similar about them so that it can generalize to this final example,” says Makin. Across the four women, the AI’s best performance was an average translation error rate of 3 per cent.
Makin says that using a small number of sentences made it _______ for the AI to learn which words tend to follow others. For example, the AI was able to __________ that the word “Bear” was always likely to follow the word “Teddy” in a certain set of sentences, from brain activity alone.
The team tried transforming the brain signal data into __________ words at a time, rather than whole sentences, but this __________ the error rate to 38 per cent even for the best performance. “So the network clearly is learning facts about which words go together, and not just which brain activity __________ with which words,”says Makin.
This will make it hard to scale up the system to a/an __________ vocabulary because each new word increases the number of possible sentences, reducing __________. Sophie Scott at University College London says we are a long way from being able to translate brain signal data comprehensively.

A new study has shown how computers and robots powered by artificial intelligence can read human eye movements to "read" human personalities.
The eyes, they say, are the windows to the soul. And if that is true, computers and robots powered by sophisticated(复杂的)artificial intelligence algorithms(算法)may soon have the ability to peer into your soul. That is the result of a new study on the connection between eye movements and personality, conducted by neuroscience researchers based at the University of South Australia and Published in the scientific Journal Frontiers in Neuroscience.
"Eye movements during an everyday task predict aspects of our personality," wrote the researchers, led by University of South Australia neuroscientist Tobias Loetscher, whose team follows 42 study subjects around the university campus recording their eye movements, then determines their personality traits(特点)with "well-established questionnaires" for determining personality type, according to a summary of the study published by the site Science Daily.
The researchers fed the data into their Al algorithms and found that computers running the algorithms were able to record human eye movements and immediately determine a person's major personality traits, such as "neuroticism, extraversion(外向),agreeableness, conscientiousness, as well as perceptual(感知的)curiosity", the scientists wrote.
"The new findings could improve the way human beings interact with their computers and other high-tech devices, even robots, allowing for more natural and realistic social interactions with machines," Loetscher said.
"People are always looking for improved, personalized services. Today's robots and computers are not socially aware so they cannot adapt to non-verbal information," Loetscher said in a statement quoted by Indian Express. This research provides opportunities to develop robots and computers so that they can become more natural, and better at interpreting human social signals."
The study revealed previously undiscovered relations between specific personality characteristics and specific eye movement tendencies, according to a summary in Britain's Daily Mail newspaper.
1.What do the underlined words "peer into" in Paragraph 2 probably mean?
A. understand B. stare at
C. search for D. concern about
2.How did the researchers conduct the research?
A. It was carried out in a lab.
B. 42 subjects' eye movements were recorded.
C. The students' daily movements were tracked.
D. Its subjects' personalities were determined by computer.
3.According to Tobias Loetscher, what can we know?
A. Robots and computers are socially conscious.
B. People care less about improved, personalized services.
C. Today's robots and computers can accustom to non-verbal information.
D. The discovery will improve the interaction between human beings and machines.
4.What can be a suitable title for the text?
A. Human Personality Traits
B. What Human Eye Movements Are
C. Tell Personalities by Eye Movements.

Siri is an artificial intelligence (AI) that you can carry around in the pocket, where it waits patiently to be told what to do. In the week we spent together, my AI assistant has performed admirably in finding me restaurants, or the location of the nearest coffee shop.
A typical command might be: “Reserve a table for two at a good French restaurant in San Francisco.” Siri responds by presenting a list of top-rated restaurants that can be booked on OpenTable.com. If you say which time you want, it can book you a table without your lifting a finger. In some ways Siri is just a fancy front-end (前端程序) to the 35 sites it can connect to, from taxi booking sites to movie review databases. But what’s new is the way it can analyze the intentions of its master or mistress and use those sites to put them into action.
Siri attaches probabilities to the explanation of each word and cross-references (对照检索) with your location and other data, some of which you must provide yourself. To send email reminders, Siri obviously needs to know your email address. To “find me the flower shop closest to work”, it needs to know where you work. To pay bills or buy airline tickets, it would need access to your credit card.
That raises the question of how far we are willing to trust a piece of software that can go and do things for us based on what it “thinks” we mean, a topic that occupies some engineers working on artificial intelligence. The more data, and power, you give your virtual assistant, the more damage it could do. Siri may be simple, and always shows its explanation of a command before carrying it out. But it gives users a preview of a new balance between privacy, trust and convenience that the expansion of AI into everyday life is likely to develop.
1.What is Siri?
A. A digital e-book reader.
B. A music-sharing software.
C. A voice-controlled website.
D. An artificial intelligence software.
2.When asked “do I need my umbrella today?”, what will Siri probably respond with?
A. The list of umbrella makers.
B. The list of umbrella shops.
C. The local weather forecast.
D. The local climate conditions.
3.Siri is new in that it has the ability ______.
A. to understand what you speak
B. to connect a lot of websites
C. to give a variety of commands
D. to create computerized database
4.What question does Paragraph 4 answer?
A. Does Siri think itself? B. Can I trust you, Siri?
C. Is Siri simple for use? D. Will Siri be popular?

The world’s first beer brewed (酿造) with the help of artificial intelligence (AI) is now on sale. Four beers have been created, with each recipe changed based on customer feedback (反馈) received by a program.
The system is hidden behind a Facebook Messenger robot, which takes feedback from customers and sends it onto human brewers who change recipes accordingly. Intelligent X, the company behind the beers, said the use of AI would help brewers receive and test customer feedback “more quickly than ever before”.
Codes printed on the bottles direct people towards the robot, which then asks a series of questions. This information is then interpreted by the program, which learns from customer feedback to ask better questions in the future.
The robot asks questions based on customer preference and flavour and answers are normally marks out of ten, yes or no and multiple choice. The AI uses a system known as reinforcement learning to learn from how it has acted and get better outcomes in the future. In this sense the AI is “rewarded” based on hard-coded biases that instruct it to please customers— those who like hoppier beers or stouts, for example.
This feedback is then accumulated to notice trends and inform the brewing process, with beers slowly changing over time.
“The AI is about putting all the customers in the same room as the brewer,” said Intelligent X co-founder Hew Leith. It would be extremely difficult and time-consuming for a human to collect this much data, Leith continued, but the AI can gather and interpret it with ease. The team behind the AI hope it could one day help them win a major beer brewing competition.
Intelligent X’s four beers have evolved eleven times so far based on initial feedback collected during trials over the last 12 months. The beers are currently being toured around in East London and are also being stocked by co-working space We Work. The four Al-brewed beers-golden, amber, pale and black—are available now from Ubrew for £ 4.50 each.
1.What can we know about the beer?
A. It is made by the customers themselves.
B. It is the first kind of beer in the world.
C. It can be changed with the feedback.
D. It can be bought from the website Facebook.
2.Who can change the beer’s recipes?
A. The human brewers. B. The customers. C. The system. D. The Facebook.
3.What do we learn from the feedback?
A. It changes the recipes of the beer directly.
B. Customers can make it via the Internet.
C. Everyone can get any kind of beer according to it.
D. It is only based on customer preference.
4.What do Hew Leith’s words tell us?
A. The AI is ready to call on all the customers to get together.
B. It was once hard for us to get the feedback from the customers.
C. The AI can consume more time to collect the necessary data.
D. The team has already won many competitions about beer.

Supercomputers which can analyse blood samples and predict which patients are likely to become seriously ill could save tens of thousands of lives a year, it was revealed last night, according to The Daily Express.
The artificial intelligence (AI) system, developed at University College London and set to be piloted in NHS hospitals later this year, will screen “at risk” patients so doctors can take early action to prevent death or serious illness. Prof Young, a consultant surgeon at Southend University Hospital, said: “I am so excited about this form of technology.”Instead of people getting sick or dying because they are not picked up in time, this will allow us to step in earlier which will save lives and an enormous amount of money. “I think the potential of AI in healthcare like this is as big as the Industrial Revolution was — and signals a completely new example in the way we manage healthcare.”
The technology is the brainchild of Dr Vishal Nangalia, a consultant at the Royal Free Hospital in London. He used AI to analyse a billion stored blood samples from 20 different UK hospital trusts dating back up to 12 years. Computers assess blood test results by picking up subtle changes in red and white blood cells, suggesting a patient is going downhill.
He found the technique forecast outcomes of patients with kidney problems with up to 95 per cent accuracy. Traditional methods highlighting serious patient concerns picked up as few as 16 percent of patients who went on to die. “This gives us the opportunity not only to save lives but to prevent serious illness, making the health service not only safer but more efficient.” Prof Young said, “Instead of waiting for people to get worse, we will be able to treat them earlier.”
1.What does the underlined phrase “screen” in Paragraph2 mean?
A.comfort. B.treat.
C.spot. D.nurse.
2.How do supercomputers help save lives?
A.By storing blood samples.
B.By analyzing patients’ cases.
C.By observing changes in blood cells.
D.By assisting doctors with their operations.
3.Why did Professor Young mention the Industrial Revolution?
A.To show the influence of AI.
B.To stress the importance of health care.
C.To introduce the topic of supercomputers.
D.To present the achievement he has accomplished.
4.What do we know about the new technology?
A.It helps patients recover earlier.
B.It has helped save thousands of lives.
C.It will promote the health service greatly.
D.It is intended for patients with kidney diseases.
