1 . Algorithms (计算程序) are able to do a huge number of tasks, and the number of tasks that they are able to do is expanding practically every day. According to a new study, despite increasing concern over the effect of algorithms in daily life, more and more people nowadays are willing to trust a computer program, especially if a task becomes too challenging. From choosing the next song on your playlist to choosing the right size of pants, people are relying more on the advice of algorithms to help make everyday decisions.
During the study, researchers asked volunteers to count the number of people of a crowd in a photograph and supplied suggestions that were offered by a group of other people and suggestions offered by an algorithm. As the number of people in the photograph expanded, counting became more difficult and people were more likely to follow the suggestions offered by an algorithm rather than count themselves or follow the “wisdom of the crowd”.
One of the common problems with AI is when it is used for awarding credit. While that is a subjective decision, there are lots of numbers there, like income and credit scores. Therefore, people feel like this is a good job for an algorithm. But we know that dependence leads to unfair and incomplete practices in many cases because of social factors that aren’t considered.
Facial recognition and hiring algorithms have come under inspection in recent years because their use has shown cultural prejudice in the way they were built, which can cause inaccuracies when matching faces to identities or screening for qualified job candidates. The prejudice may not be present in a simple task like counting, but their presence in other trusted algorithms is a reason why it is important to understand how people rely on algorithms when making decisions.
“The eventual goal is to look at groups of humans and computers making decisions and find how we can get them to trust each other and how that changes their behaviors,” one of the researchers said. “Because there is very little research in that setting, we’re starting with the fundamentals.”

2 . Alida Monaco doesn’t spend her summers doing the usual teenage work, like working at the mall. Instead,she ‘ s studying.
It used to be that a summer job was considered a teenage thing. Today, Monaco ,who has never had a summer job, is part of growing trend (趋势)teenagers focusing on their studies, even during the summer. That’s down from 72% of Americans aged 16 to 19 who worked in July of 1978, according to the U. S. Bureau of Labor Statistics.
Fierce (激烈的)competition, older workers returning to the workforce and weak economic growth are all adding to the decrease of teenagers in the workforce. But as schoolwork grows increasingly heavy and homework eats up more time, data suggest the biggest reason why some teens won’t be working this summer is that they simply don’t1 have time.
For college - bound teens, some teachers even advise students not to waste time on a summer job. “ Some of my students only have about six weeks off in the summer,” said Shannon Reed, a lecturer at the University of Pittsburgh and a former high school English teacher.” I could never advise that they get jobs during that short break. ”
Young people who don’t work may miss out on valuable skills that they’11 need control and help people learn to deal with adult situations. But Monaco, who plans to attend Harvard, isn’t fazed by her lack(缺乏)of work experience. “Maybe I have missed out on a couple of life skills, “she said. “ But I don’t think it will harm me in way .”

Technological change is everywhere and affects every aspect of life, mostly for the better. However, social changes are brought about by new technology are often mistaken for a change in attitudes.
An example at hand is the involvement of parents in the lives of their children who are attending college. Surveys (调查) on this topic suggests that parents today continue to be “very” or “somewhat” overly-protective even after their children move into college dormitories. The same surveys also indicate that the rate of parental involvement is greater today than it was a generation ago. This is usually interpreted as a sign that today’s parents are trying to manage their children’s lives past the point where this behavior is appropriate.
However, greater parental involvement does not necessarily indicate that parents are failing to let go of their “adult” children.
In the context (背景) of this discussion, it seems valuable to first find out the cause of change in the case of parents’ involvement with their grown children. If parents of earlier generations had wanted to be in touch with their college-age children frequently, would this have been possible? Probably not. On the other hand, does the possibility of frequent communication today mean that the urge to do so wasn’t present a generation ago? Many studies show that older parents — today’s grandparents — would have called their children more often if the means and cost of doing so had not been a barrier.
Furthermore, studies show that finances are the most frequent subject of communication between parents and their college children. The fact that college students are financially dependent on their parents is nothing new; nor are requests for more money to be sent from home. This phenomenon is neither good nor bad; it is a fact of college life, today and in the past.
Thanks to the advanced technology, we live in an age of bettered communication. This has many implications well beyondthe role that parents seem to play in the lives of their children who have left for college. But it is useful to bear in mind that all such changes come from the technology and not some imagined desire by parents to keep their children under their wings.

Then a visitor showed up. “Do you want to write a song?” asked Anita Kruse, 49, rolling a cart equipped with an electronic keyboard, a microphone and speakers. Simran stared. “Have you ever written a poem?” Anita Kruse continued. “Well, yes,” Simran said.
Within minutes, Simran was reading her poem into the microphone. “Some bird soaring through the sky,” she said softly. “Imagination in its head…” Anita Kruse added piano music, a few warbling (鸣, 唱) birds, and finally the girl’s voice. Thirty minutes later, she presented Simran with a CD of her first recorded song.
That was the beginning of Anita Kruse’s project, Purple Songs Can Fly, one that has helped more than 125 young patients write and record songs. As a composer and pianist who had performed at the hospital, Kruse said that the idea of how she could help “came in one flash”.
The effect on the kids has been great. One teenage girl, curling (蜷缩) in pain in her wheelchair, stood unaided to dance to a hip-hop song she had written. A 12-year-old boy with Hodgkin’s disease who rarely spoke surprised his doctors with a song he called I Can Make It.
“My time with the kids is heartbreaking because of the severity of their illnesses,” says Anita Kruse. “But they also make you happy, when the children are smiling, excited to share their CD with their families.”
Simran is now an active sixth grader and cancer-free. From time to time, she and her mother listen to her song, Always Remembering, and they always remember the “really sweet and nice and loving” lady who gave them a shining moment in the dark hour.
