The modern age is an age of electricity. People are so used to electric lights, radio, televisions, and telephones that it is hard to imagine what life would be like without them. When there is a power failure, people grope about in flickering candlelight, cars hesitate in the streets because there are no traffic lights to guide them, and food spoils in silent refrigerators. Yet, people began to understand how electricity works only a little more than two centuries ago. Nature has apparently been experimenting in this field for million of years. Scientists are discovering more and more that the living world may hold many interesting secrets of electricity that could benefit humanity. All living cells send out tiny pulses of electricity. As the heart beats, it sends out pulses of record; they form an electrocardiogram, which a doctor can study to determine how well the heart is working. The brain, too, sends our brain waves of electricity, which can be recorded in an electroencephalogram. The electric currents generated by most living cells are extremely small,often so small that sensitive instruments are needed to record them. But in some animals, certain muscle cells have become so specialized as electrical generators that they do not work as muscle cells at all. When large numbers of these cells are linked together, the effects can be astonishing. The electric eel is an amazing storage battery. It can send a jolt of as much as eight hundred volts of electricity through the water in which it lives. (An electric house current is only one hundred and twenty volts, but two hundred and twenty volts in China.) As many as four-fifths of all the cells in the electric eel's body are specialized for generating electricity, and the strength of the shock it can deliver corresponds roughly to length of its body. |
1. Electricity was invented ______. |
[ ] |
A. when man had no candles B. about 200 years ago C. to be operating computers D. by Thomse Edison |
2. The following things can send out pulses of electricity except ______. |
[ ] |
A. electric eels and human hearts B. Electrical generators and animal muscle C. Stones and dry wood D. human brain and living cells |
3. The electric current send out by an eel can be ______. |
[ ] |
A. as much as 800 volts B. about one hundred and twenty volts C. as high as the house current in China D. stored in the water where it lives |
4. From this shot passage we can infer ______. |
[ ] |
A. the shorter an eel is, the stronger electricity it produces B. we can always feel the electricity produced by living cells C. human beings get their knowledge about electricity from nature D. people learn about electricity from eels |

Sometime early in the next century,human beings will move to Mars.They will live there for about a year,and then will be replaced with another group of pioneers.Building the base on Mars will advance our knowledge of the solar system and aid in our understanding of the earth. We already know that Mars resembles the earth in many aspects:general size,presence of water,length of day,range of temperatures.These resemblances have caused many ?people? to consider a centuries?long project:to terraform Mars.Terraforming meansalteringa planet's surface so that Earth's life forms can survive there.This concept,previously found only in science fiction is now being seriously considered by scientists. Terraforming Mars is theoretically simple:add nitrogen and oxygen to the atmosphere;pump water to the surface;and add the earth's plants and animals in the order in which they developed on Earth.But it will take at least 300 years. Some people think that such a project is too huge for ?humans? to undertake,but there are very good reasons to make the attempt.The earth now contains some 6 billion ?people?,and no one has any idea of how many humans the earth can support.Our very existence and numbers are threatening many other species.We also have had some experience with terraforming our own planet:altering the landscape,the atmosphere and the climate.Currently terraforming earth has become a wiser activity as we try to control global warming,air and water pollution,and preserve some natural living places. While the possibility of such a project is small,it is not impossible.Even if earth bound societies come and go in the next 300 years,the project can continue through the work of the Mars settlers without the need for constant backing from the earth. The future existence of all the people in our world may very well depend upon our ability to terraform Mars. |
1.What would be the bes ttitle for this passage?_____ |
A.Terraforming Mars B.Saving the Earth C.Travelling to Mars D.A NewlyFound Place |
2.What does the underlined word " altering" mean in the second paragraph?_____ |
A.Warming. B.Changing. C.Planting. D.Building. |
3.According to the passage, the main purpose ofter raforming Mars is to_____. |
A.do some scientific research work B.find out its similarity to earth C.avoid the dying away of many other species D.find on Mars livingplace for the increasing humanbeings |
4.The main reason for causing many people to consider terraforming Mars is that_____. |
A.there are some resemblances between Earth and Mars B.terraforming Mars is theoretically simple C.we have had some experience with terraforming our own planet:Earth D.the development of science and technology is very rapid |
5.What's the author's attitude towards the project? _____ |
A.Optimistic. B.Negative. C.Skeptical(怀疑的). D.Objective. |
