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. |

[ ] |
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. 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 |

The meridians of longitude are imaginary great circles drawn from pole to pole around the earth. By international agreement, the meridian of longitude passing through Greenwich, England, is numbered zero. The earth is divided into 360 degrees, and the meridians are numbered east and west from Greenwich. There are 180 degrees of longitude east of Greenwich and 180 degrees in the westerly direction. New York has a longitude of 74 degrees west (74oW.) which means that it lies on the 74th meridian west of Greenwich.
Since the sun appears to travel around the earth in 24 hours, it will move 360/24 or 15 degrees in one hour. This reasoning can be used by navigators to determine their longitude. Imagine that we have set sail from Greenwich, England, after having set a very accurate clock, or chronometer, to the local Greenwich time. As we travel westward toward New York, we notice that the sun is going "slower" than our chronometer. At the time that our timepiece reads 12 o'clock, the sun has not quite reached the zenith. As a matter of fact, when our clock reads noon, what it really means is that it's noon in Greenwich, England. Our clock continues to tell us the time, not at our present location, but at Greenwich. Let us wait until the sun is directly overhead (noon at our location) and then read the time on our clock. Suppose it reads i o'clock. This means that there is one hours difference in time between our longitude and that of Greenwich. As we mentioned earlier, this corresponds to exactly 15 degrees of longitude, so our longitude must be 150 W. The world is divided into 24 time zones, and each zone corresponds to 15 degrees of longitude. New York is approximately 5 time zones west of Greenwich, so the time difference must be about 5 hours. By maintaining chronometers on Greenwich time, ships can determine their longitude on any sunny day by merely noting the difference in hours between Greenwich time and local sun time and multiplying this difference by 15 degrees.
Of course, longitude gives only half of the information needed to determine our precise location. We must also know our latitude, which tells us how far we are north or south of the Equator. The Equator is the zero line for the measurement of latitude. Circles are drawn parallel to the Equator to indicate other values of latitude. There are 90 degrees of south latitude.
In the Northern Hemisphere there is a star called Polaris almost directly over the North Pole. This makes it possible to determine the latitude of a given point by setting our sextant (六分仪) to measure the angle between Polaris;the North Star, and the horizon. Mathematicians tell us that this angle is equal to the latitude at the point in question.
To get idea of our location, therefore, we need to know local time, Greenwich time, and the angle between Polaris and the horizon.
In order to establish the "fix" or precise location of a ship, the navigator must know________.
A.his latitude
B.his longitude
C.local time
D.both his latitude and longitude
Directions: In this section you will hear several conversations. Listen to the conversations carefully and then answer the questions that follow.
听力原文:Leslie: Any specific lessons you learned in your own life in looking back?
Martha: Oh yeah, sure? How we make mistakes and keep on making them even though we recognize them.
Leslie: What mistakes have you made and kept on making?
Martha: Being too nice] No, I' m a nice guy. It’s just an interesting life, I guess. I guess it might be interesting to other people. It’s kind of dull to me though ! I didn’t find it dull until I read it. I traveled a lot and stuff like that, but I didn’t win any awards like a Nobel Prize or anything.
Leslie: Saying your life was dull? Is there anything you regret by looking back?
Martha: You don’t have much to regret when you' re dull.
Leslie: Looking back on your life, what are some of your happiest times in life?
Martha: I generally have happy times in my life all of the time. I' ye been very lucky to have an interesting life and hr positive about most of it. I forget about the bad times, to tell you the truth.
Leslie: Do you feel that mentality has helped you get through the trials in life?
Martha: I guess so. I have’t had that many trials in that respect. A lot of people take everything seriously and worry. I' m a transitional person. I' m a nomad. I travel a lot.
What does the man mean when he said that he didn't win a Nobel Prize?
A.He hasn't worked hard enough.
B.He is a traveler, and there isn’t a Noble Prize for traveling.
C.He's leading a normal life.
D.His life is interesting, though it seems dull to himself.
A.Some people do so to voice their position to a special issue.
B.Some people do so to test the impatience of the public.
C.Some people do so to express their hatred of the country.
D.Some people do so to express their political opinion.
