A new study shows students who write notes by hand during lectures perform better on exams than those who use laptops(笔记本电脑)．

    Students are increasingly using laptops for note­taking because of speed and legibility(清晰度)．But the research has found laptop users are less able to remember and apply the concepts they have been taught.

    Researchers performed experiments that aimed to find out whether using a laptop increased the tendency to make notes “mindlessly” by taking down word for word what the professors said.

    In the first experiment，students were given either a laptop or pen and paper. They listened to the same lectures and were told to use their usual note­taking skills. Thirty minutes after the talk，they were examined on their ability to remember facts and on how well they understood concepts.

    The researchers found that laptop users took twice as many notes as those who wrote by hand. However，the typists performed worse at remembering and applying the concepts. Both groups scored similarly when it came to memorizing facts.

    The researchers' report said，“While more notes are beneficial，if the notes are taken mindlessly，as is more likely the case on a laptop，the benefit disappears.”

    In another experiment aimed at testing long­term memory，students took notes as before but were tested a week after the lecture. This time，the students who wrote notes by hand performed significantly better on the exam.

    These two experiments suggest that handwritten notes are not only better for immediate learning and understanding，but that they also lead to superior revision in the future.

    Many people don't realize the importance of music education in the schools today. A new study showed, however, music education is extremely important.

    In college, music education is one of the largest programs. Teachers have to learn general education materials and techniques. They must learn to play every instrument; they must learn music history and music theory; they must learn instrument repair and teaching methods; they must learn conducting and so much more. At the same time, much of our culture and tradition is absorbed in music.

    Music plays a very important role in our education.

    Music helps with math and science. Students learn to count, and how to multiply and divide. Students also use science to help them discover what sounds good together and what doesn't. Students also need science to understand something called the “overtone series", which is about how music is produced by vibration（颤动）and why.

    Students learn a lot about languages through music．Many songs are written in other languages, including ancient ones. Students must learn to translate these works to understand what they are singing about. A song is likely to be a famous short work set to music; so students are exposed to that very often while singing.

    Students learn a huge amount of cooperation （协作）of body parts through music, so parts of the body can work better together. Students must use motor（肌肉运动的）skills in order to play an instrument. Singers and wind（管乐器）players must learn breath control and be in good shape to play.

    Students learn about art. Some famous pieces were written about important pieces of art, and students learn about the artists and styles as they're playing the music.

    Music education also brings higher thinking to our children. It allows them to think about complex patterns. Students have to be aware of what every other musician does at every time. In that way, it develops cooperation, as well. They tend to develop more ability for learning.

    As one can see, music is very important to education.

    Winter is for working hard, summer is for playing hard. From the Bahamas to Amsterdam, we have several most appealing summer vacation spots for you to choose from.

    The Bahamas

    While there is a risk of getting rained on during hurricane season, June generally sees mild weather, fewer crowds and significantly lower prices. While some resorts (度假胜地) in the Out Islands may close, New Providence and Paradise Island remain open year-round. It's a good choice for families looking for a taste of relaxing island living.

    Mackinac Island, MI

    Mackinac Island, 20 minutes by boat from either the Upper or Lower Peninsula of Michigan, comes alive on summer weekends. Most of its roughly 4 square miles is parkland, suitable for hiking and cycling. Be sure to take in the beautiful architecture―Victorian cottages that date back to just after the Civil War. You can have a taste of times gone by; cars were banned more than a hundred years ago, and horse-drawn carriages are still used to get around today.

    Ocean City, MD

    This East Coast beach town is best known for its boardwalk, which is known for old-school amusement rides. Cycling in the town is also a great pleasure. Grab your wallets and feast on hard-shelled crabs at Hooper's crab house or drink in the sunset with a local beer in hand from Fager's Island Restaurant & Bar's large bayfront decks. Parking is free with your consuming receipt. You can't miss a classic walk along the boardwalk and the taste of Thrasher's vinegar and Old Bay French fries.

    Amsterdam

    Summer is the ideal time to visit this city. The gray skies have lifted, festivals abound and events to enjoy include the Open Garden Days, when visitors can peek (窥视) into the private gardens behind the beautiful Houses that line the famous canals. You can experience urban adventure, crossing Amsterdam's thousands of bridges and waterways by bike and by boat in search of the perfect brown cafe.

    Pakistan should be everyone's tourist destination for 2018, but what if you already live there? Then perhaps you should consider visiting these five must-visit places for this year.

    Lake Saiful Muluk

    At an altitude of 3, 224m, surrounded by snowy mountains, the lake rewards those that make the three-hour uphill walk from Naran. You will find the pathway just above the free market, but the best choice is to get a jeep and share the costs with some other tourists; expect to pay about 700 rupees, worth it to view this natural beauty.

    Deosai National Park

    As another high point in Pakistan, it has an average altitude of 4,114m－the Deosai Plains are one of the highest plateaus (高原) in the world. If you make it to the park, you expect to find rich plants and wild animals. The breathtaking scenery on show at the plains is enough to make 2018 a memorable year.

    Naltar Valley

    Accessible via a 2.5-hour drive from Gilgit, well worth visiting. Covered with pine trees and other plants, it has a dreamlike feel about it. Various colors all year around make you fall in love.

    Shangrila Resort

    Right in the north of Pakistan in the central valley of Gilgit Baltistan. Locals call this a paradise (乐园), and that's what it feels like. No visit is complete without checking out the restaurant which is built in the structure of an aircraft.

    Rama Meadow (牧场)

    Doesn't feel like Pakistan at all, more like somewhere in Minnesota. Watch the sheep and cows feeding while clear water flows in streams from high in the mountains. Against Chongra's ice-covered peak, this little meadow is a piece of art.

    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."
