Five years ago, when I taught art at a school in Seattle, I used Tinkertoys as a test at the beginning of a term to find out something about my students. I put a small set of Tinkertoys in front of each student, and said:"Make something out of the Tinkertoys. You have 45 minutes today - and 45minutes each day for the rest of the week."

   A few students hesitated to start. They waited to see the rest of the class would do. Several others checked the instructions and made something according to one of the model plans provided. Another group built something out of their own imaginations.

   Once I had a boy who worked experimentally with Tinkertoys in his free time. His constructions filled a shelf in the art classroom and a good part of his bedroom at home. I was delighted at the presence of such a student. Here was an exceptionally creative mind at work. His presence meant that I had an unexpected teaching assistant in class whose creativity would infect(感染) other students.

Encouraging this kind of thinking has a downside. I ran the risk of losing those students who had a different style of thinking. Without fail one would declare, "But I'm just not creative."

"Do you dream at night when you're asleep?"

"Oh, sure."

"So tell me one of your most interesting dreams." The student would tell something wildly imaginative. Flying in the sky or in a time machine or growing three heads. "That's pretty creative. Who does that for you?"

"Nobody. I do it."

"Really-at night, when you're asleep?"

"Sure."

"Try doing it in the daytime, in class, okay?"

    Gadgets that make study fun

    Now in a world piled high with smart phones, tablets and e-readers, technology has entered the classroom in ways unimaginable. Taking classes can be fun too. All you have to do is swipe your fingers on your phone screen and download some apps, which can make your study more fun and efficient. Balancing study and play in a college setting has never been easy-and with the following few apps, it'll be tough to tell the two apart.

    Evernote

    Use: note-taking

    Can be used on: Phone/iPad/iPod touch, Android, BlackBerry, Palm OS and     Windows, Phone 7

    Price: free

It's hard to imagine that with all the magical gadgets, the eager, studious types would still take out a notepad, a pencil, and a highlighter—and take notes in class. While it's not an actual planner or a calendar App, if you take notes to stay organized, then Evernote is for you．The main thing about Evernote is that all of your notes are automatically sent into the cloud—and then you can access them from any web-connected computer via the Evernote app or a web browser. Evernote also supports audio and photo notes-rather handy if you want to record your lecture or take photos of any projected notes. But, of course, ask for permission first.

    Wikipanion

    Use: research database

    Can be used on: iPhone/iPad/iPod touch

Price :free ( Wikipanion Plus for $4.99,or 31.87 yuan )

    Now, you don't necessarily have to go to a library or anywhere with computer services to do research work for your paper anymore. You can get access to the research databases just on your smart phone or tablet. Wikipanion gives you a simplified version of Wikipedia without leaving out any of the site's extra features. The normal links that you'd see to each section of an article are no longer on the main screen. Instead, there's small icon located at the bottom of the App, which can be used to access all the sections of an article. You can also open the links in Safari(苹果浏览器). According to the developers' site, loading Wikipedia pages with Wikipanion is a lot faster than accessing the Wikipedia site from the iPhone's browsers. To be honest, we agree.

    The guzheng is a traditional Chinese musical instrument. It belongs to the zither（齐特琴）family of string instruments. It is the parent of many musical instruments of some other countries.

    The guzheng should not be confused with the guqin, another ancient Chinese zither but without bridges. Now the guzheng is zither with movable bridges and usually 21 strings, although it can have from 15-25 strings. The guzheng's strings were formerly made of silk, though most players used metal strings by the 20^th century. Since the mid-20^th century most performers use steel strings. The guzheng has a large resonant cavity（共振腔）.

    The guzheng has existed since the Warring States Period and became especially popular during the Qin dynasty. The number of strings on the guzheng has always fluctuated. There were as few as 6 to as many as 23 strings during the Tang dynasty. The earliest record of the guzheng belonged to the historian Sima Qian. Until 1961, the common guzheng had 16 strings, although by the mid-20^th century 18-string guzheng were also in use. In 1961, Xu Zhenggao, together with Wang Xunzhi, introduced the first 21-string guzheng after two years of research and development. In 1960, they also invented the “S-shaped” left string rest, which was quickly adopted by all guzheng makers and is still used today. This curve allows for greater ease in tuning the strings and, combined with strings of different thickness, allows for greater resonance in both the deeper and the higher pitch（音调）ranges. The 21-string guzheng is the most commonly used one, but some traditional musicians still use the 16-string one.

    A recent experiment proves that bees can save time and energy when they fly around to different flowers.

    Dr Nigel Raine, from the Royal Holloway University of London, has always been interested in finding out why animal behave like they do. He is also interested in bees. It was not a surprise when he and some other scientists from Queen Mary University of London discovered that bees can quickly solve a problem that takes computers many days.

    Flowers make pollen (花粉), and when bees visit them, they carry the pollen to other flowers. The plants need the pollen to make seeds that will grow. Dr Raine notes that we get a lot of our food from plants, so it is important to know how the bees move around and take the pollen between flowers. The scientists wanted to examine the journey that the bees take and how they save energy when they do this. They completed the experiment on the roof of Queen Mary University, using artificial flowers and a large amount of nectar, a sweet liquid produced by flowers. They taught one bee to visit all the flowers in one place at the same time. When the bee got to know the location of the flowers well, they saw how it flew around and returned home with the nectar. After this, they changed the locations of the flowers. The scientists thought the bee would follow the route it knew already. This would mean that it followed a longer route than it needed to, and so it would use more energy. They watched the bee carefully as it travelled between the flowers in their new location, and they made notes. But in the experiment, the bee changed its route and flew a shorter distance.

    The problem that the bee solved is similar to a maths puzzle called the 'travelling salesman problem'. A salesman who goes to different places to sell things wants to travel the shortest distance. But he has to calculate the length of many possible routes to know which one is the shortest. A computer can calculate this but the experiment shows bees can do the same calculation quickly with a tiny brain. Scientists are very interested in how they do this. It would help us to understand how pollen is moved around. In addition, if they find this out, it could help us to improve communication networks. This might help humans to reduce traffic jams when there is an accident, for example.

    The world is a truly strange place waiting to be explored. In addition to offering a lot of extraordinary locations and people, it also offers interesting festivals celebrated by people in various parts of the world. Here is a list of the oddest festivals that can be found around the world.

    Cheese Rolling Festival: A festival that is surely going to leave you with a sore neck if not a broken one! Celebrated in England, the Cheese Rolling Festival is something that you would rather watch than take part in.

    Okay! Here's how it goes. Officials set a big cheese wheel to roll down a steep hill and participants run after it. The first one to catch it wins the competition and the cheese. Simple? Well, try it out and you will know!

    The Monkey Buffet: Now here's a country that actually feeds monkeys to their hearts' content instead of chasing them away. Celebrated in Thailand, the Monkey Buffet is an annual event that brings together a lot of locals who offer fruit and vegetables to over 600 monkeys. It's a great feast as the monkeys dig into almost 3, 000 kilograms of fruit and vegetables. The people of Thailand believe this is a way to honor the Monkey King called Hanuman.

    La Tomatina: Here's your golden chance to get even with your friends who sprayed(喷洒)paint on you on your birthday. Celebrated in Spain, the month of August has nearly 250 pounds of tomatoes go down the drain(被浪费掉)in what is perhaps the largest tomato fight in the world. The event is conducted in the town of Bunyol and attracts nearly 30, 000 tourists around the world in addition to locals. Truckloads of tomatoes arrive and you are ready to go. The entire area is covered with slush and tomatoes within minutes. It's a good time to have fun with friends and family.

    Over the past 40 years, China has helped more than 700 million rural residents out of being poor, and the poverty rate(贫困率) — the proportion of people living below the Chinese poverty line — had fallen among the rural population from 97.5 percent in 1978 to 3.1 percent at the end of 2017, official figures shows. China's achievements in poverty alleviation(扶贫) made the world look at China with admiration.

    "For me, it is unbelievable that over 40 years, that is, over the course of one working lifetime, China has gone from one of the poorest countries in the world to one that is about to eliminate(消除) absolute poverty," said Craig Allen, president of the US-China Business Council.

    Varaprasad Sekhar Dolla, a professor of Chinese studies at India's Jawaharlal Nehru University, also spoke highly of China's achievements in poverty reduction. "If global poverty came down greatly in the last three or four decades, it's partly because of the Chinese contribution to reducing poverty within its own national boundaries," said the Indian scholar.

    In the eyes of Khairy Tourk, a professor of economics with the Stuart School of Business at the Illinois Institute of Technology in Chicago, "many countries look up to China to learn from its experience." "The Chinese experience is based on building a modern infrastructure(基础设施) and then on setting up special economic zones that would help underdeveloped countries to become more industrial," he added.

    In the government work report delivered at the opening of the annual NPC session (全国人大会议) on March 5, China promises to reduce its population of rural poor by over 10 million this year.
