The Tennessee valley Authority began li
2、fe in 1933 asone of the public works agencies designed to help fight the Great Depression.The TVA was first meant to employ thousands of men to build a chain of damsdown the Tennessee River. These dams were to include electric plants forgenerating electricity to provide cheap power for the rural lan
3、d in thevalley area.Within ten years, most of the homes in the TVA area had electricity. Intwenty years, there were four times as many homes in the area with power.At first , TVA electrcity cost a penny per kilowatt. Many homes in the arearelied on electricity for heating. This results in criticism
4、now that elec-tricity is more than three pennies per kilowatt. Other criticism has beenaimed at the TVAs other methods of generating power in 1975. The Authoritywas sued(?e?) for polluting the air with its coal-generating plants. Anti-nuclear groups point out that the TVA would soon have a total of
5、seventeenatomic reactor plants supplying power for its service area. But the TennesseeValley Authority has adjusted to the new times. It quickly became a modelfor pollution control at its coal plants. Just as quickly the TVA founditself an energy conserver as well as a producer. The TVA conducts fre
6、ehome energy consultations and offers cheap loans to consumers who want toinstall insulation storm windows, solar energy equipment or woodburningstoves. The resulting decrease in demand has allowed the TVA to postponeor delay construction of two nuclear reactors. Instead, the Authority isbuilding a
7、plant to extract coal gas from low-grade coal. Their first stepwill be to use the coal gas to make an ammonia(?) fertilizer for farmersin the TVA service area. Their ultimate goal is to produce a syntheticfuel from the coal gas. The TVA will then be once again producing a cheapersource of energy and
8、 helping solve the nations problems, several at atime.76.

Even at the universities, students studyonly in their concentrated area, and very few students ever venture out-side that subject again; in a real sense, the English boy or gi

The Earths gravity pulls it. But every cloud ismade of water droplets or ice crystals. Why doesnt rain or snow f
21、allconstantly from all clouds? The droplets or ice crystals in clouds areexceedingly small. The effect of gravity on them is minute. Air currentsmove and lift droplets so that the net downward displacement (?￥) iszero, even though the droplets are in constant motion.Droplets and ice crystals behave
22、somewhat like dust in the air madevisible in a shaft of sunlight. To the casual observer, dust seems to actin a totally random fashion, moving about chaotically without fixed direc-tion. But in fact dust particles are much larger than water droplets andthey finally fall. The cloud droplet of average
23、 size is only 1/2500 inchin diameter. It is so small that it would take sixteen hours to fall halfa mile in perfectly still air, and it does not fall out of moving air atall. Only when the droplet grows to a diameter of 1/125 inch or largercan it fall from the cloud. The average raindrop contains a
24、million timesas much water as a tiny cloud droplet. The growth of a cloud droplet toa size large enough to fall out is the cause of rain and other forms ofprecipitation. This important growth process is called“coalescence.“86. What is the main topic of the passage?A) The mechanics of rain.B) The cli

26、ure of rain droplets.B) The effect of gravity at high altitude is random.C) They are kept in the sky by air currents.D) They are moving about without fixed directions.89. What can be inferred about drops of water larger than 1/125 inch in diameter?A) They never occur.B) They are not affected by the
27、force of gravity.C) In still air they would fall to earth.D) In moving air they fall at a speed of thirty-two miles per hour.90. In this passage, what does the term “coalescence“ (in Paragraph 2)refer to?A) The gathering of small clouds to form larger clouds.B) The growth of droplets.采集者退散C) The fal
