Murcia

    I have spent about 8 months living in Murcia and I feel that I should put it as number one on my list. On my return from exploring other cities, I always feel like I'm returning home when I set foot in Murcia. The city centre is full of life and energy and has an incredible atmosphere all year round. Although the accent takes you a little time to get used to at first, you will adjust to it. Murcia is also home to some gorgeous(壮丽的) beaches and amazing coastal views. So it really does have the best of both worlds!

Gibraltar

    I visited Gibraltar during the Easter holidays and I was totally surprised by the beauty of Gibraltar! From a short cable car riding up to the top of the rock you are met with splendid views over the coast and the adorable monkeys which curiously come to greet you on your arrival. Make sure to hide all your food because they think it's a gift for them!

Valencia

    Valencia is beautiful. It's as simple as that! The river-area is so exciting and full of life, all the way up to the science museum and beaches. However, I was a little confused by the fact that the river had long been filled in and turned into a park, yet people still referred to it as The River.

Alicante

    I have spent many a weekend in Alicante, making the most of the beautiful beach in low season, before all the tourists arrive. May is the high season here, so I'd definitely recommend a visit in April, September, or October, just before or after the holiday season.

    If you have a long holiday to spend, where can you go?

    Nikoi Island, Indonesia

    Less than 85 km-but somehow a whole world away-from Singapore's shining skyline lies Nikoi Island. Surrounded by white sandy shorelines and vivid coral reefs, Nikoi's centre is hidden in rainforest, resulting in amazing biodiversity seen in its native plants, animals and bird life. Marrying traditional Indonesian craftsmanship with contemporary design, Nikoi boasts just 15 stilted（建于支柱上的）beach houses, all with breathtaking sea views, guaranteeing privacy and total escape from the daily routine.

    Amanpulo, Philippines

    The only property on Pamalican Island, the luxurious Amanpulo resort offers extremely impressive accommodation, with only access to over five kilometres of clean coral sand beach. Designed to resemble local Bahay Kubo homes, Amanpulo's beachside, treetop and hillside villas all feature comfortable decks（木质平台）with hammocks（吊床）from which to enjoy the spectacular views of the greenish-blue sea below. Fill your schedule with Amanpulo's signature adventures (including diving, windsurfing and sailing), recharge in the award-winning spa or feast on locally caught seafood-the choice is yours.

    Song Saa, Cambodia

    Song Saa's incredible ocean views, and breathtaking sunsets are a very typical example of pure paradise. Its 24 villas—each with their own sea-view private plunge pool-are designed to reflect the natural beauty of Cambodia's coastline; built from recycled wood with straw roofs and driftwood furnishings, these presences are stylish proof of Song Saa's admirable commitment to sustainability and conservation. You can choose to do as much or as little as you want here. With rainforest tours, island safaris and reef snorkeling（徒手潜水）, it just offers some of the activities that show this spectacular destination.

    While the start of a new school year is always exciting, this year was even more so for some elementary school students in Auckland, New Zealand. They became the world's first kids to be" taught" by a digital teacher, Will. Will is just an avatar(用户头像)that appears on the student's desktop, tablet, or smartphone screen, not a human-like robot walking around the classroom.

    Auckland energy company Vector and AI company Soul Machines worked together to develop Will, which has been modeled after the human brain and nervous system, allowing it to perform human-like behavior. The digital teacher is currently assigned to teach Vector's" Be sustainable with energy, "a free program for Auckland elementary schools.

    Just like the humans it replaced, Will is able to instantly react to the students' responses to the topic. Thanks to a webcam(网络摄像头)and microphone, the avatar not only responds to questions the kids may have, but also picks up non-verbal cues(非口头提示).For instance, if a student smiles at Will, he responds by smiling back. This two-way interaction not only helps capture the students' attention, but also allows the program's developers to monitor their engagement, and make changes if needed.

    Vector's Chief Digital Officer, Nikhil Ravishankar says," What was fascinating to me was the reaction of the children to Will. The way they look at the world is so creative and different, and Will really captured their attention."

    Will, in place since August 2018,has been a great success thus far. However, regardless of how popular it becomes, Will is unlikely to replace human educators any time soon .For one, the avatar's knowledge base is severely restricted. But more importantly, even the smartest digital avatars could never predict and react to all the unexpected situations that educators have to deal with on a daily basis. However, it could come in handy as a" personal tutor", providing kids with one-on-one help on specific subjects or even topics.

    When Gitanjali Rao shared how she likes "finding solutions to real problems”, it was hard to imagine this dynamic 11-year-old girl could settle a problem that has escaped scientists for years.

    In just three months, Rao came up with a device（装置）that can replace the costly and lengthy tests currently used to reliably determine lead levels in our fresh water. Inspired by the current litigation （诉讼）in Flint, Michigan, a case of water pollution from 2014 to 2015, Rao designed a new testing system that resulted in her being named America's Top Young Scientist for 2017.

    Rao had been following the water problem for about two years. She was amazed by the number of people affected by lead pollution in water and wanted to do something to change this. Gitanjali spent months trying to convince local high schools and colleges to give her lab time to continue her experiment. At home, Gitanjali worked on her project in the "science room” she asked her parents to create for her. Rao has created a device that uses three parts: a cartridge, a Bluetooth reader and an app. To put it simply, the cartridge contains carbon nanotubes（纳米管） that react to lead. This reaction is then registered by the Bluetooth reader, which sends a signal to a mobile app that can tell you immediately if your water is safe to drink.

    Rao appropriately named the device Tethys after the Greek goddess of fresh water, and is hoping to make a little improvement to get the device on the market. While we may not be aware of any lead pollution present in our aging pipelines, lead poisoning can cause delays in physical and mental development. With Rao believing that the "purpose of science is to make a difference”, her incredible invention could make a difference to millions of people in the United States.

    A new study has found that social media could be affecting the sleep of young adults.

    The study is a project of researchers at the University of Pittsburgh's School of Medicine. They found that young people who often use social media are more likely to suffer from sleep disorders than those who use social media less. The researchers say doctors should ask young adults about their use of social media when treating sleep issues.

    "This is one of the first pieces of evidence that social media use really can influence your sleep." said Jessica C Levenson. She was the lead author of a report on the study.

    The researchers set out to examine the connection between social media use and sleep among young adults. Levenson noted that these young adults are possibly the first "generation to grow up with social media."

    The researchers wanted to find out how often young people used social media sites like Facebook, Twitter, Credit and Tumbler. For the study, they gave questionnaires to nearly 1,800 adults, aged 19 to 32. On average, members of the study group used social media sites one hour a day. They also "visited various social media 30 times per week."

    Thirty percent of the study's participants reported having serious problems with sleeping. Those people who used social media a lot were three times more likely to have a sleep disorder. And those who spent the most time on social media were two times as likely to suffer from sleep disturbances.

    Levenson said the number of times a person visits social media is a better predictor of sleep problems than overall time spent on social media. If this is true, she adds, then practices that stop such behaviors may be the most effective.

    One day after school, Bill walked past the shop on the street corner as usual. He stopped to look at the front row of shoes, and he felt sorry for himself.

    He really wanted to have a new pair for his birthday. He sadly walked away and

    thought of how to tell his mother. He knew she would give him anything if she could. But he also knew she had little money. He decided not to go home at once, because he looked worried and he didn't want his mother to worry about him. So he went to the park and sat on the grass. Then he saw a girl in a wheelchair. He found that the girl moved the wheels with her hands. Bill looked at her carefully and was surprised to see that the girl had no feet.

    He looked down at his own feet. "It was much better to be without shoes than without feet," he thought. It was not right for him to feel so sorry and sad. He went away and smiled, thinking he was luckier in life.
