1 . We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices(装置) well after they go out of style. That’s bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things.
To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life — from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation — Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.
As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices — we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions(排放)more than doubling during the 1992 to 2007 window.
So what's the solution(解决方案)? The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.

3 . Adults are often embarrassed about asking for help. Its an act that can make people feel sensitive. The moment you ask for directions, after all, you reveal (泄露) that you may be lost. Seeking someone’s assistance can make you feel like you are broadcasting your incompetence. New research suggests young children don’t seek help in school, even when they need it, for the same reason.
To learn more about how children think about seeking help, we asked 576 children, ages four to nine, to predict the behavior of two kids in a story. One of the characters genuinely wanted to be smart, and the other merely wanted to seem smart to others.
Children thought that the kid who wanted to seem smart would be less likely to ask for assistance. They could still conceive of (想象) situations in which the kid who wanted to seem smart would seek help: when assistance could be sought privately (on a computer rather than in person), children thought both characters were equally likely to ask for it.
We also found that they recognize several more behaviors that might make a child appear less smart in front of fellow kids, such as admitting to failure or modestly downplaying successes. Children are therefore acutely aware of several ways in which a person’s actions might make them appear less clever in the eyes of others.
However, a number of solutions can be found to help children. Our Gist instinct may be to motivate seeking help by emphasizing its educational benefits. But reputational barriers likely require reputation-based solutions. For example, instructors could create activities in which each student becomes an “expert” on a different topic, and then children must ask one another for help to master all of die material. If seeking help is understood as a commonplace classroom activity, kids may be less likely to think of it as indicative (表明) of one’s ability.
Seeking help could even be framed as socially desirable. After all, asking for help often benefits not just die help seeker but also others listening in who have similar questions or struggles.
