Bicycles are a great way to get around. They’re fun to ride, especially down hills. And, as you speed along the road, you might also think of ways in which you could improve your bike— make it safer, more efficient, or more comfortable. In fact, the two-wheeled machines make for some cool science projects.
This year's Intel International Science and Engineering Fair (ISEF), held last May in Cleveland, featured(had)three bicycle projects from three countries. Like many of the other experiments presented at ISEF, the bike projects showed that some of the most interesting scientific research often begins by taking a closer look at things you care about.
Renato Angulo Chu had even grander ambitions. The 12th-grader from Lima, Peru, wanted to address some of his country's economic troubles.
"I see a problem in my country," Renato said. "If you go to the forests in Peru, in some places you cannot find electricity. If you go with my bicycle, you can turn on the lights."
Renato, 16, spent 3 years designing his special Multibike. The device looks like a fixed exercise bike. It has wires fixed along the frame and a blender strapped (fastened) to the back. Turning the pedals operates the blender. The same principle can be used to sharpen knives or sweep city streets.
The Multibike can work either as a fixed bike or as a bicycle able to travel city streets and country roads. It's made from inexpensive materials, and the user gets exercise while pedaling to operate a machine.
"You pedal the bike, and you can mix any drink you want," Renato said. More importantly, he added, the same concept could be used to bring light to houses in remote regions of the rainforest.

Things you need to know about studying there
Study style
Since the 1950s, the Netherlands has had courses in English especially for foreign students. Students are expected to be critical of what they read and hear, and to be able of working independently. Foreign students will soon notice that at Dutch institutions for higher learning people are expected to do a lot of talking. The most common form of teaching is the seminar or working group, where a small group of students work under a teacher’s supervision to analyze(分析)a certain problem. On exams, they have to show that they know the material, and that they have formed well-founded opinions on the subject.
Accommodations(住宿)
If you are in an exchange programme or an international course, it is quite possible that a room will be arranged for you. Accept it immediately, or you will regret it later. That’s because finding a place to live in a country as crowded as the Netherlands is not easy.
Before you leave China, ask your host institution whether or not housing will indeed be arranged in advance. If you are in the Netherlands and still looking for a place, ask the international relations office or the student dean for advice.
Expences
Tuition: (學(xué)費(fèi))
Bachelor’s degree:about 2,500 euros a year
Master’s degree: 5,000-12,000 euros a year

Student about 450-700 euros a month.

Litre of milk: 0.5—0.8 euro
Kilo of apples: 1.5 euros
Shampoo, 400ml: 4 euros
Tube of toothpaste: 1 euro
Bed sheet: 20 euros
Other expenses:
Haircut: 15 euros
Air ticket to China: 600-800 euros
Mobile phone call(one minute): 0.1-0.3 euro
Phone call to China (with IP card): 7 euros(one minute)
Postage stamp in the Netherlands: 0.39 euro
Stamp for China: 0.78 euro
(1 euro-about 10 yuan)
Transportation
Trains, buses and trams run throughout the country.
If you really want to sample Dutch life, and get around quickly and easily, buy yourself a bicycle. Most students buy second-hand bicycles. A reasonable one will cost you 70-120 euros.

Bicycles are very popular in China. In our country you can see bicycles almost everywhere. When you walk on the road, you will find a lot of people riding bicycles to schools, shops and anywhere else. Therefore, China is known as “the kingdom of bicycles”. In China, many families have one or two bicycles.
Compared with cars, bicycles have many advantages. First, they are much cheaper than cars. Most Chinese can’t afford cars, but they can afford bicycles.

However, bicycles also bring some problems. Some riders don’t obey the traffic rules and some riders don’t think about others safety. So they ride too fast. During the rush hour, too many bicycles may cause traffic accidents. We still have a long way to solve the problem.
