    A Kickstarter launched Friday will allow interested parties to set up a camera and pet toys in their home for anyone to play with their pets remotely. It's called the ipet Companion, an Internet-connected camera and device that streams video online and allows basic commands from people watching. They can move the camera, look at their pet and press a button to swing a toy around.

    Obviously, demand is strong. The Kickstarter proved so popular that Scott Harris, iPet Companion's founder, said that thousands of people started asking for it.

    The reason why people keep talking about this is the emotional(情感的) connection they have from a thousand miles away. If you want, you can enter a queue to move the camera and play with the pets. Each room has toys that are hooked(钩住) into Internet-connected devices, and you can move them by pressing a button.

    But there's sort of a problem: Pets get bored easily. Young pets will stay more interested than adult pets, but finally even a baby pet will get bored, too. To stop that from happening, you'd better limit the pets' access(接近) to the boys and change the place where they're located in the room.

Harris understands this and said you can plug anything into that adapter(适配器) —toys that you can get on your own. And that's where the iPet Companion really gets interesting. Harris explained that the device is actually sort of a Trojan horse to bring the “Internet of things” to more homes. You don't really have to use it for pets. The adapter could be used for any device with an electrical plug—a sprinkler, say, that you'd be able to activate to water your grass.

    “Our whole goal, our whole purpose is to let anyone control any physical object that they want to while they travel anywhere in the woorld,” Harris said.

    Tyler Kellogg drove more than 3,000 miles last year. His goal is to help as many people as he can.

    Tyler Kellogg calls himself a long-time do-gooder, and last summer he really did a lot of good. After collecting together $2,000 and using his car as a sleeping space, the 21-year-old college student hit the road. His goal was to do random acts of kindness for 100 strangers.

    He drove 1,600 miles, from his parents' house in Adams Center, New York, to the Florida Keys, then back again. “The first person I helped was a person fixing a boat lift on a lake in Oneida, New York,” Kellogg remembers. “I was shaking when I asked if he needed a hand.” What if he thought Kellogg was crazy? “When he said, ‘can you help me get this lift into the water?' I knew everything was going to be fine.”

    He helped a policeman fix a downed barricade(路障) in Washington, D.C., and spread many yards of mulch(护盖物) in Maryland and North Carolina. And somewhere outside Atlanta, he met a man who was crying because his wife had recently died and he had no one to talk to. “For three hours we sat in his garden,” Kellogg says. “When I left, he said, ‘Thank you. I realize now that my life will go on.' ”

    In 55 days, Kellogg helped 115 strangers and made an exciting discovery. “You don't have to have much money,” he says. “You just have to ask people, ‘How can I help?' ”

    Recently, people in US education have gotten extremely worried because a new report has shown that American students have a math problem.

    The 2015 Program for International Student Assessment(评估)(PISA) shows math scores in the US getting lower and no improvement in science or reading. PISA tests 15-year-olds from different countries and regions in their math, science and reading skills. About 540, 000 students from 72 countries and regions took part in the assessment in 2015.

    US scores in reading and science were about the same as three years ago, leaving Americans near the middle of the bigger group. But the situation in math is much more worrying. The US average score was 470, below the OECD(经合组织)test average of 490, meaning the US was No. 40 among the 72 countries and areas. It was 12 points lower than in 2012 and 18 points lower than in 2009. So, what is going on with American students' math skills?

    One reason may be that the US does not teach math in enough depth. "Students are often good at answering the first part of a problem in the United States, "said Andreas Schleicher, director of education and skills at OECD. "But as soon as students have to go deeper and answer the more complicated part of a problem, they have difficulties. "In comparison, many high-performing countries and regions in math teach a lot less but focus in much greater depth,  especially when you look at East Asia, Japan and Singapore, according to Schleicher.

    Another reason may be the fact that many people in the US are unwilling to travel to foreign countries to learn better teaching practices. "One of our biggest challenges in the US is that the teachers are not going out and seeing what high-performing countries do differently, "said Wendy Kopp, who started Teach for America, in a news program.

    Being physically active three times a week reduces the odds of being depressed by about 16%, according to new UCL research carried out as part of the Public Health Research Centre.

    The study, published in JAMA Psychiatry, found a two-way relationship between depression and physical activity. People who increased their weekly activity were reported to have fewer depressive symptoms but those with more depressive symptoms were less active, particularly at younger ages.

    Researchers followed 11,135 people born in 1958 up until the age of 50, recording depressive symptoms and levels of physical activity at regular intervals in adulthood. They found that each additional activity period per week reduced odds of depression by 6%. In England 19% of men and 26% of women are currently classed as "inactive", and this study suggests that activity could significantly improve their mental as well as physical health.

    "Assuming the association is causal, physical activity has a protective effect against depression. If an adult between his twenties and forties who isn't physically active became active 3 times per week, he would reduce his risks of depression by about 16%," said Dr Snehal of the UCL Institute of Child Health, lead author of the study.

    Professor Mark，Director of the Public Health Research Centre, said: "Many people are already aware of the benefits of physical activity on their general health, but now we are seeing more evidence that suggests it also has a positive effect on a person's mental well-being. The latest research highlights just how important it is to ensure that people are working and living in environments that allow them to be both physically active and mentally healthy."

    The morning after an evening flight with my then three-year-old daughter, I couldn't wait to get her to school. I was tired from the anger, and her inability to communicate because of her slowed language development.

    As I accompanied her into the car, I felt desperate. Nothing was right with our world. She had been born around the same time the nation was witnessing the birth of another Great Recession(经济萧条). My job and my house had been victims. Then this happened. My child's language delay was identified, but doctors struggled to properly diagnosis her. I felt like we both needed to be rescued.

    I returned that afternoon as disenchanted with the little girl I loved as when I left.

Walking slowly toward the school's playground gate, I found her preschool teacher racing to greet me.

    “You should have seen her today!” His breathy words were supported by excitement.  I didn't interrupt. “See that climber.” He pointed to a piece of wooden playground equipment that looked like a rock wall. I nodded. “Well, every day since she started school. She's tired and failed to make it to the top.” He took a breath. “And today she made it.

    He expressed his joy just like he'd witnessed her conquering (征服) Mount Everest “She cheered and celebrated! I wish I'd recorded it.” His words comforted me. My daughter had conquered her mountain. As she ran toward me, I recognized something I hadn't before. I saw her perseverance. I saw her strength. I saw a hero.

    "What kind of rubbish are you?" This question might normally cause anger, but in Shanghai it has become a special "greeting" among people over the past week. On July 1st, the city introduced strict trash-sorting regulations (条例)that are required to follow and expected to be used as a model for our country. Residents must divide their waste into four separate categories and toss (投放)it into specific public dustbins. They must do so at specified times, when monitors are present to ensure correct trash-tossing and to ask the nature of one's rubbish. Individuals who fail to follow the regulations face the possibility of fines and worse. They could be punished with fines of up to 200 yuan ( $ 29). For those who repeat to go against them, the government can add black marks to their credit records, making it harder for them to get bank loans or even buy train tickets.

    Shanghai government is responding to an obvious environmental problem. It generates 9 million tons of garbage a year, more than London's annual output, which is rising quickly. But like other cities in China, it lacks a recycling system. Instead, it has relied on trash pickers to sift (筛选)through the waste, picking out whatever can be reused. This has limits. As people get wealthier, fewer of them want to do such dirty work. The waste, meanwhile, just keeps piling up.

    Many residents appear to support the idea of recycling in general but are annoyed by the details. Rubbish must be divided according to whether it is food, recyclable, dry or harmful, the distinctions among which can be confusing, though there are apps to help work it out. Some have complained about the rules concerning food waste. They must put it straight in the required public bins, forcing them to tear open plastic bags and toss it by hand. What they complain most is the short periods for dropping trash, typically a couple of hours, morning and evening. Along with the monitors at the bins, this means that people go at around the same time and can keep an eye on what is being thrown out no one wants to look bad.
