5 . “No matter where you are or what time it is there’s something going on at a Hard Rock Cafe. All over the world our cafes not only serve great food, but they serve up great music.” Hard Rock Cafes around the world symbolize the timeless energy, originality and unifying (团结的) spirit that have helped to shape rock music over the last century.
Founded by two Americans, the first Hard Rock Cafe (HRC) opened its doors to the public on June 14, 1971, in London. Today, HRC has become a global phenomenon with more than 180 cafes in different countries.
HRC has also become the world’s leading collector and exhibitor of rock ‘n’ roll memorabilia. It all started when Eric Clapton, a regular at the first HRC, asked the staff if they could hang his guitar on the wall to mark his favourite stool (凳子) as “his spot”. They did and one week later, a package from Pete Townshend arrived with a guitar and a note with the message, “Mine’s as good as his! Love, Pete.”
Ever since then, Hard Rock Cafes have been collecting pieces of rock memorabilia and covering their walls with them. Their collection is rotated from restaurant to restaurant and provides the world’s most comprehensive “visual history” of rock ‘n’ roll. These treasures include an awe-inspiring collection of classic guitars and other instruments, posters, music, etc.
Throughout its history, HRC has been governed by a special service philosophy: “Love All — Serve All.” Since it was established, HRC has taken part in a wide variety of humane activities around the world. Following its idea of being more than just a restaurant, HRC tries to connect its business and its passion to make the earth a safer, healthier and better place to live.
All in all, Hard Rock Cafe International is an entertainment company that continues to successfully expand the Hard Rock brand through countless music-related activities.

6 . Traditionally, robots have been hard, made of metal and other rigid material. But a team of scientists at Harvard University in the US has managed to build an entirely soft robot-one that draws inspiration from an octopus (章鱼).
Described in science journal Nature, the “Octobot” could pave the way for more effective autonomous robots that could be used in search,rescue and exploration. “The Octobot is minimal system which may serve as a foundation for a new generation of completely soft, autonomous robots” the study’s authors wrote.
Robots built for precise, repetitive movements in a controlled environment don’t do so well on rough terrains (地形) or in unpredictable conditions. And they aren’t especially safe around humans, because they’re made out of hard and heavy parts that could be potentially dangerous to their users.
So researchers have been working on building soft robots for decades. They’re taken inspiration from nature, looking to animals from jellyfish to cockroaches, which are often made up of more flexible matter.
But creating a completely soft robot remains a challenge. Even if engineers build a silicone (硅酮) body, it’s still a grand challenge to construct flexible versions of essential parts, such as a source of power.
“Although soft robotics is still in its early stage, it holds great promise for several applications, such as search-rescue operations and exploration,” Barbara Mazzolai and Virgilio Mattoli of the Italian Institute of Technology’ Center for Micro-BioRobotics, wrote in a comment. “Soft robots might also open up new approaches to improving wellness and quality of life.”

7 . At the age of seven, while his friends were spending their allowances on things like candy and toys, Jose Adolfo Quisocola was busy saving money for basic purchases. To try to get his peers(同 龄 人 ) to do the same, the boy from Peru came up with the idea of an eco-bank, the Bartselana
Student Bank, which allows kids of all ages to become financially independent while also helping the environment.
Set up in 2012, the bank is the world’s first bank for kids. To become a member, a kid has to bring in at least 5 kilograms of solid waste and set a savings goal. Once accepted, all bank “partners” are required to deposit at least one additional kilogram of recyclables on a monthly basis and observe other requirements, such as attending financial education and environmental management workshops.
The waste accumulated is sold to local recycling companies, who, thanks to Jose’s efforts, pay a higher-than-market rate for everything brought in by the bank members. The money received is placed in the personal account where they collect until the savings goal is reached. The account holder can then withdraw the money, or choose to leave it and continue to grow for a bigger target. “At the beginning, my teachers thought I was crazy or that a child could not undertake this type of project,” Jose recalls, “They did not understand that we are not the future of the country but its present. Luckily, I had the support of the school headmaster and an assistant in my class.”
The boy’s efforts paid off, and by 2013, the bank had over 200 members, who brought in one ton of recyclable waste. Today, the eco-bank, which now has the support of several local institutions, boasts ten educational centers. They are designed to teach the over 3,000 students, aged 10 to 18 , to become financially independent, use their money wisely, and help the environment.
Not surprisingly, Jose’s efforts have earned him several national and international awards. On November 20, 2018, Jose won Children’s Climate Prize, which comes with a medal and $5,500 in prize money and is given to a child or youth who has accomplished an extraordinary achievement for the climate or environment.

8 . Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.
Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.
There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.

9 . We’ve all experienced peer pressure (同伴压力) . It happens to everybody. However, people have different reactions. Confident people refuse to do things they don’t want to do, but shy and anxious people often give in. It may be because they want to be liked. It may be because they worry that their friends will make fun of them, or perhaps they’re just curious about trying something new.
