     Readingcan be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website BookCrossing.com turns the page on the traditional idea of a book group.

      Members go on the site and register the books they own and would like to share. BookCrossing provides an identification number to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.

    Bruce Pederson, the managing director of BookCrossing, says, “The two things that change your life are the people you meet and books you read. BookCrossing combines both.”

    Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.

    People who find a book can also leave a journal entry describing what they thought of it. E-mails are then sent to the BookCrossing to keep them updated about where their books have been found. Bruce peterson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.

    BookCrossing is part of a trend among people who want to get back to the “real” and not the virtual(虚拟). The site now has more than one million members in more than one hundred thirty-five countries.

    Mexico sites on an island plateau (高原) surrounded by volcanic peaks, which makes air quality a constant concern for people who live there.

    In April, the country took a decisive step toward improving air quality by enacting a temporary ban on private and Federal vehicles in the city. The rule forbids people from driving in the city one day each week and one Saturday each month. Electric vehicles, government service vehicles, public transport options and school buses are not included in the ban.

    Mexico City isn't the first urban center to be involved in car-free living. But the ban is more than an awareness-raiser. It was enacted with the direct aim of solving air pollution. In March, the city sank into a deep brown haze of smog when the pollution levels passed the 200 mark. The city ordered some 1.1m of the area's 4.7m cars off the streets and also offered free bus and subway rides.

    Mexico City's temporary vehicle ban raises questions about the best ways to improve urban air quality. India, whose citizens breathe some of the world's dirtiest air, has tried a variety of solutions. Earlier this year, the Indian government started a 4% sales tax on new-car purchases.

    Beijing also has experience with cleaning the air. The city introduced alternate-day rules in advance of the 2008 Olympic Games, which produced good results. And then there is the London congestion (拥挤) charge, introduced in 2003. The charge has had a measurable effect on air quality.

For now, Mexico City — named by the United Nations as the most polluted city on the planet in 1992 — can look forward to the start of the region's rainy season, when daily showers will help lo clean the air.

    A new study, which was published in the American Journal of Preventive Medicine, found that heavy use of platforms such as Facebook and Snapchat was associated with feelings of being separated from society among young adults—basically the opposite of what we are led to believe.

    Study co-author Brian Primack and his team surveyed 1,787 U. S. adults aged 19 to 32 and asked them about their usage of 11 social media platforms. They also asked participants questions related to social isolation, such as how often they felt left out. The participants who reported spending the most time on social media—over two hours a day—had twice the odds of perceived（感知到的）social isolation than those who said they spent a half-hour per day or less on the same sites.

    According to Tom Kersting, psychotherapist and author of Disconnected, the key to understanding these results lies in our understanding of “connections.” “Humans are social —emotional beings, meaning that it is in our DNA to be connected, face-to-face, with other humans,” he told Reader's Digest. “Although people think being on social media all the time makes them 'connected' to others, they are actually 'disconnected,' because the more time one spends behind a screen, the less time one spend face-to-face.”

    “Part of the issue of loneliness is that the majority of people who use social media aren't just posting, they are also viewing,” Kersting continued. “They are spending a lot of time looking at everyone else's posts, where they are and what they are doing. The constant exposure to everyone else's 'perfect' life experiences causes feelings of being left out.”

    So what's the answer? It's simple, says Kersting. “The solution to this is resisting the temptation to look at everyone else's life. Just focus on your own life, where you're going, what you are grateful for, and what you want to accomplish in this world.”

    There was great excitement on the planet of Venus this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs. The satellite was directed into an area known as Manhattan. Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information about the feasibility of a manned flying saucer landing on Earth. A press conference was held at the Venus Institute of Technology. "We have come to the conclusion, based on last weeks satellite landing, "Prof. Zog said, that there is no life on Earth.”

    “How do you know this? "the science reporter of the Venus Evening News asked "For one thing, Earth s surface in the area of Manhattan is composed of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide and other deadly gases and nobody could possibly breathe this air and survive. “Are there any other sources of danger that you have discovered in your studies?

    “Take a look at this photo. You see this dark black cloud staying over the surface of Earth? We don' t know what it is made of, but it could give us a lot of trouble and we shall have to make further tests before we send a Venus Being there.”

    “Over here you will notice what seems to be a river, but the satellite findings indicate it is polluted and the water is unfit to drink.”

    “Sir, what are all those tiny black spots on the photographs?

We're not certain. They seem to be metal particles that move along certain paths. They give gases, make noise and keep crashing into each other.

    “Prof. Zog, why are we spending billions and billions of Zilches to land a flying saucer on Earth when there is no life there?"

    “Because if we Venusians can learn to breathe in the Earth atmosphere, then we can live anywhere.”
