Bicycles are a great way to get around. They are 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, 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 can not 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 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 road. 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.
1. What can we learn from the first paragraph?
A. Bicycles are the best way to go about.
B. Bikes should be made more comfortable to ride
C. You can improve your bicycle for science research.
D. Many inventions are connected with the bicycle.

A. ISEF is an exhibition displaying bicycle experiments designed by students.
B. Looking closely at things you are concerned about can lead to scientific research
C. Renato’s improvement of the bicycle has solved the country’s great problem.
D. Renato’s special bicycle will soon be put into use in remote areas.
3. The underlined word “address” in the third paragraph probably has the same meaning as _______.
A. make address written B. give up C. work at D. speak at
4. Renato’s special Multibike has all the following functions except ______.
A. making knives sharp

C. producing electricity
D. operating a machine with its own electricity
5. It can be inferred that Renato’s special bicycle is mainly designed for ______.
A. distant areas in the rainforest without electricity
B. the use of his own family to make life easier
C. the competition of ISEF to win money to support remote rainforests
D. enough exercise by pedaling it.

In a world with limited land, water and other natural resources(资源), the harm from the traditional business model is on the rise. Actually, the past decade has seen more and more forests disappearing and the globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable(可持续的)ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the healthy while using its supply of natural resources.
Today, sustainable development is a popular trend in many countries. According to a recent study, the global market for low-carbon energy will become three times bigger over the next decade. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy resolution. It is now trying hard to made full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil(棕榈油), which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown more than 50%.
Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emissions(排放) and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development. Finally, governments can avoid the huge public expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate the change from the traditional model to a sustainable one.
The major challenge of this century is to find ways to meet the needs of a growing population within the limits of this single planet. That is no small task, but it offers a large of new chances for sustainable product industries.

In 1971, readers around the world were astonished by some photographs which appeared in newspapers. Hidden deep in the rainforests of an island in the Philippines, was an ethnic (种族的) 36 called the Tasaday. Not until that moment did anyone have any 37 of these people. They didn’t have an agricultural economy; they hunted animals and 38 fruit from the plants in the rainforest. They carried tools made of stone, lived in 39 and wore clothes made of leaves. Unknown until 1971, they 40 became world famous. After that, there were TV 41 and books about them; people said their simple lives showed that human beings could be good and kind if they were not 42 by modern life. Then after 1974 the region was closed by the government and the world 43 about them.

In 1986, a Swiss journalist, Oswald Iten, decided to visit the Tasaday. The journey 44 thick rainforests and across rivers was hard and dangerous. Mr. Iten was 45 killed by the soldiers, villagers and businessmen who wanted to take the wood from the rainforest. Finally, Mr. Iten 46 and found the caves of the Tasaday 47 . The people were living in nearby huts and they were all 48 jeans and T-shirts, not leaves. He thought that perhaps they were not an ethnic minority 49 .

When he 50 to Switzerland, Mr. Iten wrote about the Tasaday people in the newspapers. He said he thought that they were just ordinary farmers, poor, but not 51 from anyone else. He believed that in 1971, the government told “the Tasaday” to 52 they were native people from thousands of years ago, so that tourists---and money---would start 53 into the region.

One group of experts said that they really were people who had no 54 with modern life before 1971; another group said they were just 55 the part. So who are these people, really? Perhaps we’ll never really be sure.

1. A. man B. group C. chief D. tradition
