How important has Internet become in our lives? The Pew Research Center conducted a survey to celebrate the Web's 25th birthday. The researchers were greatly heartened by what they found.

"In 2006, only 14 percent of American adults used Internet. Today, it's 87 percent," said Lee Rainie, the director of the Pew Research Center's Internet Project. "It is what has impressed us the most."

The survey also showed that 70 percent of the Internet users have been treated kindly or generously online while 25 percent of respondents said they have been treated unkindly. More than half—56 percent—of users said they've seen an online community come together to help someone solve a problem. 25 percent said they've left an online group because members were too unpleasant.

When Pew asked questions about whether being online has enriched people's relationships—or not—the results were very positive: 67 percent of Internet users said their online communication with family and friends has generally strengthened those relationships. Only 18 percent said it has generally weakened those relationships.

According to the survey, 53 percent of Internet users said Internet has become the hardest tech tool to give up. It is 15 percent higher than the result of a similar survey conducted in 2006. In fact, more people said they would have a harder time stopping using Internet than giving up TV. (These days, so much great television streams across the Internet that it makes sense.)

"In our survey, we have found that the Web makes a few people very unhappy. There's strong evidence pointing to the fact that Internet users tend to compare their daily lives with the ‘highlight moments' of their friends' lives," said Lee Rainie. "It's really silly."

We greet people we know and people we don't know. Doctor Aka stopped and gave greetings to the men sitting along the way. Ayah and I came to a little store to buy bread and candies. It wouldn't do, to arrive at the joy empty-handed.

It's the end of my 7-month stay in an Uzbek village teaching English and I was walking down the dirt roads with my host parents — Doctor Aka and Nurse Ayah. We drew close to a relative's house, Shakhnoza Sister's, whose children we love. "Let's see the baby. We can't just go by without seeing the little Kyrgyz (吉尔吉斯人)," laughed the Doctor. It's his personal joke to call the lovely baby a Kyrgyz.

We then continued our joy. There are endless occasions to throw party in this village. Birthdays, weddings, buying a car, a holiday — all call for throwing a party. The occasion in this evening was the return of a relative and his wife from working in Russa. Ayah and I joined the women in their separate pace. All the aunts were present. We enjoyed Russian chocolate, drank green tea, told stories, tasted Osh — a rice dish of Central Asia.

My departure (离开) in a few weeks was now a main topic: we were planning to have a good-bye party, to cry, to keep in touch by Skype, and for me to invite them to my wedding. The last blessing was given by the oldest person present. We headed out the gate amid "Bye, Cathy! Come again!" "Okay! Come to our house next time!" …

Seven months ago I didn't know these people or their language. I didn't know that I would visit from place to place and find them just that joy.

From learning about protecting wild animals and natural habitats to reading about the effects of recycling, books are perfect for showing people how to get involved. Here are four of such books.

Tall Trees

Describing the wildlife that lives in Northern California's redwood forests, it turns story time into a counting lesson as readers count all the creatures in the forests. Readers will also love remembering Tony Frederick's playful poetry about the animals of the forest.

Save the Bees

Bethany Stahl has a whole series of "Save the..." books, and they all have great lessons for readers. The explanations are fun and perfect for animal lovers who want to learn how to make a difference. On her website, she even has links to free books, which are great resources for parents or teachers.

My Friend Earth

The message of this book, written by Patricia MacLachlan, is beautiful and simple, encouraging kids to learn about Earth and all that it does. It has acute die-cut (模切) design, which is fun for little hands to explore, although those under 4 might need some help. It covers a wide range of topics and will help kids gain an appreciation for everything from rain and wind to bears and birds.

Thank You, Earth

The author of this book, April Pulley Sayre, has written many award-winning books, and this one is truly special. It was written in a letter format (格式), thanking Earth for so many great natural moments. You'll find beautiful pictures in this book.

Twenty-four trains, nine countries, 13,500 miles.

They are the numbers behind a train journey one man took from Southampton in the UK to eastern China. Roger Tyers, 37, spent a month on board trains and over $2,500—almost three times the cost of a return flight—to travel to the Chinese port city Ningbo for academic research in May, 2019. It was the climate crisis that drove this socialist to choose this complex route. Tyers told CNN that he felt it necessary to stop flying when UN climate experts warned last year that the world has less than 11 years to avoid disastrous levels of global warming.

Tyers is not the sole person to avoid air travel in response to climate change. Thousands of people worldwide have publicly promised to stop flying, including teenage activist Greta Thunberg, who has inspired youth climate protests around the world. Activist Maja Rosen started the "Flight Free"campaign in Sweden in 2018 with the aim of encouraging 100,000 people not to fly for one year.

Rosen, who stopped flying 12 years ago, says the "Flight Free"campaign helps fight the sense of hopelessness many people feel when it comes to dealing with climate change. "One of the problems is that people feel there's no point in what you do as an individual. The campaign is about making people aware that if we do this together, we can actually make a huge difference,"she said.

A passenger's footprint from an individual flight depends on a number of factors, including how far he flies, how full the plane is, and what class he travels in: First class passengers are given more space than economy passengers, meaning they're responsible for a bigger part of the plane's emissions. Tyers said that his train journey to China produced almost 90% less emissions than a return flight.

What made Tyers go to China by rail? (no more than 5 words)

As people travelling by air become increasingly aware of their carbon footprint, flying has become not only one of the most polluting industries, but also one with the most potential to turn things around.

After Solar Impulse 2 completed the world's first flight by a solar-powered aircraft in 2016, airlines and aircraft producers looked to become the first to provide a commercial plane. Bertrand Piccard, one of the pilots responsible for Solar Impulse 2's journey said, "Al1 the clean technologies we've already had can be used everywhere. We have to use them, not only for the environment, but also because they are profitable and able to create jobs."

The following year saw many projects in the aviation (航空) field as the airline industry acknowledged the future of low- carbon transportation methods. In 2017, Zunum Aero, a small aviation company which focused on delivering a range of hybrid-electric (混合电动的) planes received financial aid from JetBlue and Boeing, whilst EasyJet teamed up with Wright Electric to develop battery-powered aircraft and NASA also announced its plans to develop its own electric aircraft.

Orkney Islands, lying about 20 miles north of the Scottish mainland, are rich in renewable resources, especially the wind energy. Loganair, a Scottish airline, is cooperating with aviation companies to make Orkney the world's first fully electric airline routes. However, this is never easy. Due to the limited size and weight of a battery that an airplane can carry, airplane producers are faced with a bottleneck—the continued power supply for electric airplanes. They believe the abundant wind energy in Orkney could be the key to solving it.

The benefits of electric air travel transcend its low-carbon emissions. Aviation experts believe these aircraft's power source will also mean they will be less noisy, smaller, require less maintenance costs, and need a shorter runway to take off and land—this could lead to more airports in small cities and more rural areas being connected to the world at large.

Many people think that listening is a passive business. It is just the opposite. Listening well is an active exercise of our attention and hard work. It is because they do not realize this, or because they are not willing to do the work, that most people do not listen well. 

Listening well also requires total concentration upon someone else. An essential part of listening well is the rule known as ‘bracketing'. Bracketing includes the temporary giving up or setting aside of your own prejudices and desires, to experience as far as possible someone else's world from the inside, stepping into his or her shoes. Moreover, since listening well involves bracketing, it also involves a temporary acceptance of the other person. Sensing this acceptance, the speaker will seem quite willing to open up the inner part of his or her mind to the listener. True communication is under way and the energy required for listening well is so great that it can be accomplished only by the will to extend oneself for mutual growth.

Most of the time we lack this energy. Even though we may feel in our business dealings or social relationships that we are listening well, what we are usually doing is listening selectively. Often we have a prepared list in mind and wonder, as we listen, how we can achieve certain desired results to get the conversation over as quickly as possible or redirected in ways more satisfactory to us. Many of us are far more interested in talking than in listening, or we simply refuse to listen to what we don't want to hear.

It wasn't until toward the end of my doctor career that I have found the knowledge that one is being truly listened to is frequently therapeutic(有疗效的) In about a quarter of the patients I saw, surprising improvement was shown during the first few months of psychotherapy(心理疗法), before any of the roots of problems had been uncovered or explained. There are several reasons for this phenomenon, but chief among them, I believe, was the patient's sense that he or she was being truly listened to, often for the first time in years, and for some, perhaps for the first time ever.

Samantha Whiting, from Texas, USA, was on holiday with her family in California earlier this year when every parent's worst nightmare came to life.

While playing on the beach, Samantha spotted her 10-year-old daughter Hayley drifting out into deeper water. She called Hayley back to shore, only for the youngster to realise she was caught in the rip current (离岸流) and couldn't swim back in. The current was dragging her out to sea rapidly and she called for her mum to help her as Samantha desperately tried to reach her little girl. "I will never forget her face when she said, ‘Mum, help me!'" Samantha told KFSN, recalling the terror in her daughter's voice. She managed to reach her daughter but wasn't able to swim her back to shore and the pair were struggling.

Nearby, Kevin Cozzi and his girlfriend heard the screaming. He quickly jumped into action when he realized Hayley was in danger."I've been swimming since I was 3 years old competitively, so I felt like I could get to them,"Cozzi told KFSN. "I ran out there and as soon as I got to the mum, I just told her to give me her daughter because I knew she was struggling."He swam Hayley back to shore and a lifeguard rushed to help the 10-year-old, meanwhile Samantha was thanking the total stranger who had saved her little girl from drowning.

"If it were not for him coming to help me, there's no way that we both would have made it," the grateful mum said.

Months went by, and Samantha only knew Cozzi's first name and that he lived in Merced, California. However, she never stopped looking for the heroic bystander.

Earlier this week, she posted about the rescue in a Facebook group called Merced Neighborhood Watch, and within hours they reconnected. 

Cozzi and his girlfriend had to put off their wedding because of COVID-19, and Samantha decided to set up a GoFundMe account to help Cozzi and his girlfriend have the wedding of their dreams. Both Samantha and Hayley have been invited to the wedding, set for next fall, and look forward to once again thanking Cozzi in person. Cozzi was thankful for their fundraiser, but told journalists,"That girl being saved was enough for me."
