阅读理解

As missing children age, their appearances are quite different from their last known photographs, which makes finding them tough. Now AI could make it quicker to match any found children to those old photos.

Police can use software to age photos of people who have been missing for a while, but these tend to work best in adults, as age-related changes to adult faces are more predictable and so easier to simulate(模拟).

With children, these aged images don't tend to be like the older child, and matching photos of found children to old images in a database of missing children is difficult.

Now Debayan Deb, a professor at Michigan State University, and his colleagues have created an program to do this for them. They trained a face-recognition program on data sets including the Children Longitudinal (纵向的) Face data set, which contains images of nearly 1000 children aged between 2 and 18 years old. Each was photographed at least four times over a period of six years.

The AI learned to match recent photographs of children with images taken 2. 5 years earlier 80 per cent of the time.

With one year between the two photographs, the method was 90 per cent accurate at identifying faces. This dropped to 73 per cent after three years. The approach beats comparing children with photos taken when they were aged 0 to 4 that have been aged by software, which hovers at 50 per cent recognition after six months. The new AI might help to improve accuracy of this kind of software as well.

"This is a very good paper that could potentially be used to identify missing children," says Amarjot Singh at the University of Cambridge.

Deb's next goal is to extend the age gap. His team also hopes to develop an app that could be used to fight child trafficking (拐卖).

(1)、The software which police has used can    .
A、match photos of found kids to former images B、predict the changes of people over time C、produce accurate images of children D、age the photos of missing people
(2)、Why it is difficult to match photos of found children to their old images?
A、Because the data set of child face images is quite large. B、Because the software can't age the photos of those kids. C、Because aged images aren't very alike to the older child. D、Because it's difficult to recognize the older kids with photos.
(3)、It can be learned that Deb's team    .
A、helps police identify missing children B、intends to develop a new app C、improved the software used by police D、will give their app to police
(4)、What do we know about the approach created by Deb and his colleague?
A、It is based on the Children Longitudinal Face data set. B、It can recognize children's images between 2 and 18. C、It is more accurate than the software to match photos. D、It has been used to identify missing children.

“How's it going? ” I ask the barista(服务生). “How's your day been?”

    “Ah, not too busy. What are you up to?”

    “Not much. Just reading. ”

    This,small talk, is one of the key rituals(规矩)of American life. It has taken me only a decade to master.

    I immigrated to the United States in 2001, for college. I brought only my Indian experience in dealing with shopkeepers and tea sellers. In Delhi, where I grew up, when doing business, people don't ask each other how the other's day has been. They might not even smile. The customer doesn't tremble before complaining about how cold his food is. Each side believes the other will cheat him.

“God, Mahajan, you're so rude to waiters!” Tom, an American friend, said, laughing, after he watched me ordering food at a restaurant, in the West Village, years ago. Considering myself a mild and friendly person, I was surprised. Tom always asked servers how they were doing or praised their shirts or made jokes about the menu. At that time, this seemed dishonest to me. Did he really like what they were wearing?

American life is based on a principle that we like one another but won't violate one another's privacies. This makes it a land of small talk. Two people greet each other happily, with friendliness, but might know each other for years before asking basic questions about each other's backgrounds. The opposite is true of Indians. At least three people I've sat next to on planes to and from India have asked me, within minutes, how much I earn as a writer (only to turn away in disappointment when I tell them).

Living in Brooklyn and then in Austin, Texas. I made coffee shops the places of my movements. Meeting the same baristas day after day produced context, and I got practice. I was beginning to fit in. It felt good and didn't seem fake anymore.

    As he applied sunscreen to his young daughter's face, Dara O'Rourke, a professor of environmental and labor policy at the University of California, Berkeley, found himself wondering if the lotion(霜) was safe. He realized there was no readily available answer. The result—two years, a team of chemists, lots of testing and venture capital(风险投资) later—is GoodGuide. com. Launched in 2008, this is a website with a smart phone app that rates 140, 000 consumer products (only in America) according to their safety, environmental sustainability and the ethics of the firms that make them. Now GoodGuide has created a new “purchase analyzer” app designed to inform consumers not just about the values attached to products, but also about whether they are the virtuous(有信誉的) shoppers they say they want to be.

    Using the new app requires selecting a series of characteristics, which range from whether the user favours organic products to buying only from firms with a good human-rights record. Consumers then scan the bar code on a product with the camera in their smart phones. The app identifies it and checks in a database to score it. Much therefore depends on the quality of the data, which GoodGuide gathers from various sources, including government reports, scientific studies, and research by its own staff. If the product scores badly, the app will recommend an alternative item which is rated more highly. The app also tracks a consumer's purchases to see how well he lives up to his selected values, giving a sort of personal virtue rating.

    So far, GoodGuide has mostly been used by shoppers who are keen to know about any issues connected with products they buy. They are mothers concerned about a child's health, older people facing a chronic(慢性的) illness or supporters of a cause, such as animal rights. The hope behind the app is that the idea of finding out about a product's background will become the mainstream.

    Consumers rarely change their buying habits, even when provided with scientific and other data, says Mr O'Rourke. So he has drawn on insights from behavioral economics, which show shoppers can be greatly influenced by peer pressure and by information passed on to them by people they know. The app tries to take advantage of these pressures. The virtue rating will inform consumers how well they are doing according to the values they espouse(拥护). That measurement encourages them to do better. Soon, the rating will be able to be shared with others on social media sites such as Facebook, which could inspire a shopper to consume more thoughtfully.

    In 1977, a dead author of detective stories saved the life of a 19-month-old baby in a most unusual way. The author was Agatha Christie, one of the most successful writers of detective stories in the world.

    In June 1977, a baby girl became seriously ill in Qatar, near Saudi Arabia. Doctors were unable to find out the cause of her illness with confidence, so she was sent to Hammersmith Hospital in London. She was then only semi-conscious and on the "Dangerously Ill" list. A team of doctors hurried to examine the baby only to discover that they, too, were confused by the very unusual symptoms (症状). While they were discussing the baby's case, a nurse asked to speak to them.

    "Excuse me," said Nurse Marsha Maitlan, "but I think the baby is suffering from thallium (铊) poisoning(中毒)."

    "What makes you think that?" Dr. Brown asked. "Thallium poisoning is extremely rare."

    "A few days ago, I was reading a novel called A Pale Horse by Agatha Christie," Nurse Maitlan explained. "In the book, somebody uses thallium poison, and all the symptoms are described. They're exactly the same as the baby's."

    "You're very thoughtful and you may be right," another doctor said. "We'll carry out some tests and find out whether it's thallium or not."

    Tests showed that the baby had indeed been poisoned by thallium, a rare metallic substance(物质) used in making special glass. Once they knew the cause of the illness, the doctors were able to give the baby the correct treatment. She soon recovered and was sent back to Qatar. Later it was reported that the poison might have come from an insecticide (杀虫剂) used in Qatar.
