题目内容

A solar pump(太阳能水泵 ) was built in a desert small village. The pump used the deserts most common resource – sunlight, to increase its greatest need, water. Solar collectors were used to collect the sun’s rays. Flat collectors were used instead of concave (凹的) collectors. Flat collectors can be still and do not have moving parts, which can be broken in sandstorms. The system used the 20C temperature difference between the solar collectors and the ground water to work a steam engine which pumped water from under the ground.
Some of the social effects of the new pump were planed for. Children aged 6—15 used to meet the old men to receive the informal education there. In order to replace this, a school was also included in the project. But the project had not considered the traditional power structure of the village. As soon as the foreign experts left, the two richest men in the village took control of the pump and started selling water to everyone else. The result was that the majority of the people were poorer than before.
16. The basic function of the solar collectors is to ______
A. pump water           B. gather the sun’s rays
C. start engine            D. raise the temperature
17. According to the passage which of the following statements could be true?
A. Solar collectors were concave collectors
B. Flat collectors can be broken in sandstorms.
C. Concave collectors may be have moving parts.
D. A solar pump is a solar collectors.
18. The underground water is pumped by means of ______.
A. solar collectors B. the 20C temperature difference C. the system D. a steam engine
19. Another plan was also included that_____.
A. some new pumps were to built ,too
B. children from aged 6—15 were required to meet old men.
C. a new school would take the place of the informal education.
D. the richest men in the village would control the pump.
20. From this passage , it can be inferred that_____.
A. the project was good , but people there disliked it.
B. only few rich men supported the project.
C. the project was successful even though it only brought good social effects to fewer villagers.
D. the project was a complete failure, because the result was against its purpose.

It is midnight on September 22, 2012. The sky above Manhattan，New York is filled with a curtain of colorful light. New Yorkers are fascinated by the beautiful aurora (极光). However, their fascination is short-lived.
Within a few seconds, electric bulbs dim and flicker (闪烁), then become unusually bright for a few seconds. Then all the lights go out. Within 90 seconds, the entire eastern half of the US is without power.
Besides the US, Europe, Japan and China are also hit by the same terrible event. It is a violent solar flare (太阳耀斑) ,150 million kilometers away on the surface of the sun.
Science fiction? No. A report funded by NASA and issued by the US National Academy of Sciences in January this year says it could happen.
A massive solar flare is most likely on a spring or autumn night in 2012, according to the report.
Solar flares are huge explosions on the surface of the sun. In a matter of just a few minutes they heat material to many millions of degrees and release as much energy as a billion megatons (百万吨) of TNT explosives. Solar flares release a stream of charged high-energy particles (粒子). They are called “solar winds”.
If one solar “wind” should hit the Earth’s magnetic shield (磁场), the result could be terrible for humans.
But there’s no need to run for cover from solar winds. They do not harm life on Earth, they only affect the way we live, especially since we depend so much on modern technology. They can pump extra electricity into power lines and pipelines, causing blackouts and fuel leaks. Solar winds are also known to affect mobile phone operations and may disrupt wireless Internet services.
Moreover, solar winds can prevent normal satellite operations, and disrupt radio communications and navigation systems such as the Global Positioning System.
Auroras are powered by solar wind. This wind blows past the Earth at about 400-700 km per second and creates storms in the Earth’s magnetic environment. In the polar regions these explode into southern or northern polar lights.
The most serious solar storm that hit Earth in history happened in 1859. It caused the failure of telegraph systems in Europe and North America.
So, for humans, the sun is a double-edged sword. Without the sun, there would be no life on Earth. Without the sun, Earth would be a frozen dark ball floating in space. However, on the other hand, the sun can disorder our lives from time to time.
56. What is the main idea of the passage?
A. It introduces to readers the advantages and disadvantages of the sun.
B. It describes a science fiction set in Manhattan on 22 September 2012.
C. It shows readers the way in which solar winds form inside the sun.
D. It explains what solar flares are and their effects on human life.
57. The first two paragraphs are written ____.
A. to show a beautiful scene in a true story
B. to describe the beautiful scenery of Manhattan
C. to describe the power problem around the world
D. to introduce the topic of this passage
58. What can we conclude from the passage?
A. Solar flares will do great harm to those who are using the Internet.
B. Solar flares cannot reach as far as the polar regions.
C. Solar flares are huge explosions that happen inside the sun.
D. But for our reliance on technology, solar flares wouldn’t
affect us so much.
59. Solar winds will likely affect us in the following ways EXCEPT that ____.
A. normal satellite operations will be stopped
B. the lights in the areas affected will go out at the same time
C. people on the streets will be struck to death
D. some navigation systems will be out of order
