3 . A solar tree is a structure like a tree that generates solar energy using photovoltaic panels (太阳能光伏板). It helps solve an urgent global challenge: Replacing greenhouse gas-emitting energy sources like oil and gas with renewable energy. But the power generation potential of solar trees is relatively limited, and their primary purpose is to raise public awareness about renewable energy by getting people to notice and interact with solar energy in new ways.

Solar trees generally have a firm metal, plastic, or stone base that extends up and out into “branches” on which solar panels are mounted. Beyond this basic structure, there is great diversity in the design of solar tree units. The solar tree’s photovoltaic “leaves” absorb sunlight, converting it into electricity that is conducted down through the trunk-like central pillar of the structure to an inside battery. Many designs feature rotating (旋转的) panels that can move throughout the day in order to obtain the greatest amount of sunlight.

Solar trees help power homes, businesses, and public services. They can create shade to help reduce the urban heat island effect and provide shelter in severe weather such as rainstorms and heatwaves, creating greater urban adapting ability in the face of climate change. They also enhance public spaces, providing charging stations, and powering streetlights.

In comparison to other kinds of ground-mounted solar panel devices, solar trees don’t require much land. They make solar energy generation possible in areas with little land that can’t support vast solar arrays, as well as places that lack sufficient rooftop space for panels. However, solar panels are much cheaper than solar trees at present and have far greater energy generation capacity. Therefore, present solar tree designs often serve as a extra source rather than as a primary energy source.

At present, solar trees aren’t designed as large-scale solar projects, which limits their ability to contribute to the low-carbon energy transition. Still, their varied designs are appealing. This makes solar trees effective at displaying and thereby educating people about solar energy, and promoting a business or organization’s commitment to renewable energy.

6 . Pat Patterson, a pilot for 25 years, had never met anyone like the handsome young man in the wheelchair who faced him at the Medford, Oregon, airport on July 28, 1976. Mike Henderson, a quadriplegic (四肢瘫痪者), wanted flying lessons.

As a 22­-year-­old Coast Guardsman eight years before, Henderson had fallen off a dock and landed on a floating log, breaking two of his bones. Doctors said that he would probably never walk again, let alone fly. “Here was this doctor telling me how it was going to be,” he says, “but no one was going to limit my freedom to try.”

Henderson parked his wheelchair next to the airplane and began to climb up onto the wing. He injured his elbow on the way, and after a great struggle, finally managed to pull himself into the airplane’s pilot’s seat. In the flight office, Pat Patterson watched in disbelief. “He crawled his way up that wing!” he says. “It took him 45 minutes. When I went out, he was sitting in the pilot’s seat, bleeding from his injured elbow all over the place. When I saw him go through that much pain, I knew nothing could stop him.”

Now everything was up to the instructor and the student, and together they set about solving each problem as it arose. A small piece of carpet gave Henderson traction (摩擦力) to climb the slippery wing. A headset freed his hands from the radio microphone, and the two men developed a moving bar that enabled Henderson to operate the airplane more easily.

Three weeks and eight flying hours after the first lesson, Henderson and Patterson happily phoned Dr. Stoddard — Henderson’s physician. At the airport, as the physician looked on, Henderson quickly wheeled himself around the airplane, doing a thorough, professional ground check. With Patterson and Dr. Stoddard on board, he went through his preflight instrument check. Minutes later, engine starting, the plane rolled down the runway and took off into the gray sky.

10 . For lots of kids, toddlerhood (幼儿期) is an important time for friendship. Studies show that the earlier kids learn to form positive relationships, the better they are at relating to others as teenagers and adults. Playing together also helps these kids practice social behaviors, such as kindness, sharing, and cooperation.

Even so, how quickly your child develops into a social creature may also depend on his temperament(性格). Some toddler s are very social, but others are shy. In addition, the way that toddlers demonstrate that they like other children is markedly different from what adults think of as expressions of friendship. Research at Ohio State University in Columbus found that a toddler’s way of saying “I like you” during play is likely to come in the form of copying a friend’s behavior.

This seemingly unusual way of demonstrating fondness can result in unpleasant behavior. Regardless of how much they like a playmate, they may still grab his toys, refuse to share, and get bossy. But experts say that this is a normal and necessary part of friendship for kids this age. Through play experiences, toddlers learn social rules. That’s why it’s so important to take an active role in your toddler’s social encounters by setting limits and offering frequent reminders of what they are. When you establish these guidelines, explain the reasons behind them.

Begin by helping your child learn sympathy (“Ben is crying. What’s making him so sad?”), then suggest how he could resolve the problem (“Maybe he would feel better if you let him play the ball.”). When your child shares or shows empathy(同理心) toward a friend, praise him (“Ben stopped crying! You made him feel better.”).

Another way to encourage healthy social interaction is by encouraging kids to use words- not fists-to express how they feel. It’s also important to be mindful of how your child’s personality affects playtime. Kids are easy to get angry when they’re sleepy or hungry, so schedule playtime when they’re refreshed.
