3 . Like many couples, Sheila and David Hoffman enjoy travelling. Since 2000, they’ve often visited relatives in Australia and enjoyed holidays in many European countries including France, Germany, Italy, and Greece. And they’ve toured around America, but they haven’t once stayed in a hotel. The Hoffmans are part of a growing number of people who use their home as a way to have inexpensive holidays. So far, they’ve swapped their three-bedroom London home with people who want to stay there for anything from a week to two months.

In a home swap, you offer your house as a place to stay and anyone who’s interested gets in touch. If your dates and requirements fit, then you make a deal to exchange houses for an agreed time. The exchange can involve more than just a place to stay — some homeowners also exchange cars and others will arrange for a friend or neighbour to be on call in case of emergencies. Some exchangers will even organise restaurant bookings and trips.

Home swaps have existed in Britain on an organised basis for decades but they really took off with the arrival of the Internet. Previously, the process was long and drawn-out, involving letter exchange and expensive international calls to complete arrangements. Now, it can all be done with a few clicks. Most home-exchangers register (注册) with a specialist home-exchange company that deals with the organisation.

More people are using their homes as a way to enjoy holidays at home as well as abroad. Most of them choose to follow the trend because they are interested in how natives lead their lives. When you live in a typical home rather than a hotel, it’s almost like an exchange of lifestyles. It’s also a cheap way to travel making sure you won’t run short of money on your journey.

4 . When you're feeling low or even a little depressed, what do you want to do? The answer for most of us is not very much. Our natural response to a bad mood is to rest with our comfort of choice and hibernate (蛰伏) a bit.

But according to new science, the best way to fight off the depression is to force yourself to get out there and do something new. You might have to drag yourself off the sofa, but this research shows you'll be happier for the effort.

For the study, the research followed the daily movements of 122 study subjects, using the location-tracking features of their phones for three to four months. They also sent subjects regular text messages asking them to report on their mood.

The scientists discovered the more people visited new and different locations, the happier they felt both that day and the next. Variety and novelty seem to lift our mood. “We also find that if we feel better today, we're likely to move around and have more novel experiences and have more experiential diversity the following day," study coauthor and NYU psychology professor Catherine Hartley said.

"These results suggest a reciprocal link between the novel and diverse experiences we have during our daily exploration of our physical environments and our subjective sense of well-being." Hartley commented.

This isn't the first time science has linked new experiences with positive brain benefits. Previous studies have shown that new and challenging experiences light up learning centers in the brain. Just as experience has probably taught you, you learn a lot faster when you get outside your comfort zone. If you've been stuck at home a lot lately, it's no shock that you feel lazy. Your brain is missing out on the novelty and exploration it desires. The good news is, if you can force yourself to do something new, you'll feel you can grow smarter.

5 . Future football stars

Football academies were set up by leading football clubs so their coaches could run trials to discover and train talented boys from as young as eight as potential players for their first team.

This means that in Britain there are at least 9,000 boys at any one time attending academies after school who think they are going to be a famous footballer.     1     One eight-year-old was selected for Chelsea Academy and he went from being top of his class at school to being the boy who was messing around at the back. His mother asked him why he wasn’t trying hard at school any more. His reply was that he was going to be a footballer and be rich, so he didn’t need to. In the end, he only lasted a year in the academy.     2     And he wasn’t so discouraged that he never played football again.

    3     Any sport where only a few can get to the top has many talented failures. These people are very good and do their best but finally it will not pay off because they are just not outstanding enough. In football, this effect is big because the number of players chosen by academies is so huge.     4    

This doesn’t put off all the boys who are spotted by the big football clubs and are desperate to join the academies.     5     They get to play as much football as possible. The skills become part of them, as they are with professional players, so they are automatic and the boys don’t have to think about them when they’re on the football field.

8 . The national outpouring of grief(悲痛) at the death of two legendary academicians(院士)over the weekend, as if people had lost beloved members of their own families, offers much food for thought.

At 1:02 pm on May 22nd, 2021, liver surgeon Wu Mengchao, 99, died in Shanghai. He is known as the founder of hepatobiliary surgery(肝胆外科) in the country and was the teacher of roughly 80 percent of the nation's experts and doctors specializing in liver surgery today. Wu operated on thousands of patients, and saved at least 16,000 lives. Five minutes later in Changsha, Hunan province, agricultural scientist Yuan Longping died at the age of 91. He was known as the father of hybrid rice who helped lift the nation out of hunger.

With their dedication to science and commitment to the people, the two devoted their lives to saving lives and improving people's livelihoods. Together with generations of their students, they not only made a big difference to the lives of the Chinese people, but also many living in other developing and least-developed countries.

Wu insisted that medical science is humanity while Yuan's lifelong dream was always to enable the Chinese people to fill their own bowls with rice. What makes Wu and Yuan great is not only their achievements, but also their shared attachment to the people. The public's spontaneous(自发的) outpouring of grief at their deaths, which has been rare in the country for decades, shows how much their down-to-earth dedication to improving people's lives touched hearts throughout the country.

Yuan and Wu are just two representatives of the large numbers of scientific workers that have devoted their lives to their research, giving the country's people-centered development principle with more practical meaning. The country needs more scientists to inherit and carry forward their spirit. Even those in other walks of life can draw inspiration from the two academicians' commitment to their dreams, care for the people, and unconcern about material enjoyment, so as to make the best of what life grants for themselves and others.

9 . Rome can be pricey for travelers, which is why many choose to stay in a hostel (旅社). The hostels in Rome offer a bed in a dorm room for around $25 a night, and for that, you’ll often get to stay in a central location (位置) with security and comfort.

If I had to make just one recommendation for where to stay in Rome, it would be Yellow Hostel. It’s one of the best-rated hostels in the city, and for good reason. It’s affordable, and it’s got a fun atmosphere without being too noisy. As an added bonus, it’s close to the main train station.

If you love social hostels, this is the best hostel for you in Rome. Hostel Alessandro Palace is fun. Staff members hold plenty of bar events for guests like free shots, bar crawls and karaoke. There’s also an area on the rooftop for hanging out with other travelers during the summer.

If you’re looking for cleanliness and a modern hostel, look no further than Youth Station. It offers beautiful furnishings and beds. There are plenty of other benefits, too; it doesn’t charge city tax; it has both air conditioning and a heater for the rooms; it also has free Wi-Fi in every room.

Hotel and Hostel Des Artistes is located just a 10-minute walk from the central city station and it’s close to all of the city’s main attractions. The staff is friendly and helpful, providing you with a map of the city when you arrive, and offering advice if you require some. However, you need to pay 2 euros a day for Wi-Fi.

10 . For riders of the Lopifit, getting from A to B is as easy as putting one foot in front of the other, with its unusual design helping users to ride around by walking.

Designed by Dutchman Bruin Bergmeester, the electric walking bike called Lopifit is a mixture between a scooter (踏板车), an electric bike and a treadmill (跑步机).

According to Lopifit’s website, bike lover Bergmeester came up with the idea while training in the gym, wondering: “How can I use the treadmill outdoors? What about a treadmill on wheels?”

Four years ago the first Lopifit was created in the Netherlands, now the Lopifit firm is selling the bikes to several countries, including the United States, Mexico and the Caribbean.

The bikes use a motor to support the treadmill, so using the bikes takes “no more effort…than a walk in the park”. As the rider walks, sensors (传感器) record the turning treadmill and kick the motor into gear (齿轮) to support the movement and set the wheels in action.

Lopifit’s bikes come with a heavy pricetag (价格标签), at $2,495 (£1,980) per bike. But bikers can choose their walking bike with a series of colours.

At present, the company is struggling to keep up with the orders from all over the world. Bruin Bergmeester, CEo of the company, says smiling : “Our goal is to make the electric walking bike available for as many people as possible. We want to change the way people move. We wish that everyone can benefit from a greener and cleaner way of transportation that naturally improves your health.”
