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.
2. Which of the following is true according to the passage?
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
B. mixing any kind of drinks
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.

科目:高中英語 來源:2011-2012學年廣東佛山市高明區紀念中學高二第一學段考試英語試卷(帶解析) 題型:閱讀理解

In a world with limited land, water and other natural resources(資源), 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(可持續的)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(棕櫚油), 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.
【小題1】The traditional business model is harmful because of all the following EXCEPT that____.

A.it makes the world warmer
B.it consumes natural resources
C.it brings severe damage to future
D.it makes growth hard to continue
【小題2】What can we infer from Paragraph2?
A.China lacks wind and solar energy
B.China is the leader of the low-carbon market
C.High-speed trains are a low-carbon development
D.Palm oil is made at the cost of valuable forests
【小題3】To fully develop the low-carbon markets, governments can______.
A.cut public expensesB.forbid carbon emission
C.develop public resourcesD.encourage energy conservation
【小題4】We can learn from the last paragraph that business have many chances to _______.
A.develop sustainable productsB.explore new natural resources
C.make full use of natural resourcesD.deal with the major challenge
【小題5】What is the main purpose of the passage?
A.To introduce a new business modelB.To compare two business models
C.To predict a change of the global marketsD.To advocate sustainable development

科目:高中英語 來源:2012屆福建省高二下期末聯考英語題 題型:完型填空

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 (種族的)  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

2. A. knowledge         B. impression           C. doubt                D. fear

3. A. grew              B. enjoyed          C. collected            D. stored

4.A. huts               B. houses               C. apartments           D. caves

5. A. certainly         B. suddenly         C. absolutely           D. privately

6. A. advertisements        B. services         C. stations         D. programs

7. A. refused               B. separated            C. spoilt               D. conquered

8. A. forgot                B. knew             C. talked               D. thought

9. A. around                B. through          C. over             D. along

10.A. once              B. almost               C. often                D. even

11.A. arrived               B. left             C. hid              D. began

12.A. dirty             B. valueless            C. accessible           D. empty

13. A. making               B. selling              C. wearing          D. designing

14. A. in all               B. at all               C. after all            D. above all

15. A. returned             B. went             C. traveled         D. drove

16. A. absent               B. secure               C. different            D. free

17. A. agree                B. pretend          C. admit                D. consider

18. A. looking              B. falling              C. turning          D. pouring

19. A. contact              B. competition          C. agreement            D. patience
