Recent research suggests that the warming trend (倾向) of the past hundred years or so may be coming to an end. During the past ten years, scientists tell us that the temperature of the world has dropped a little. This would have effects on wind and rain in the weather picture.
Scientists believe clouds may be an important factor (因素) in changing the amount of heat on the earth. Another possibility is that man's agriculture and industry ways may affect the natural weather.
The weather of the world seems to be getting ______.
A．hotter
B．colder
C．warmer
D．freezing
Every geologist is familiar with the erosion cycle. No sooner has an area of land been raised alive sea-level than it becomes subject to the erosive forces of nature. The rain beats down on the ground and washed【51】the finer particles, sweeping them into rivulets and then into rivers and out to sea. The frost freezes the rain water in cracks of the rocks and breaks【52】even the hardest of the constituents of the earth's crust. Blocks of rock dislodged at high levels are brought down by the force of gravity. Alternate heating and【53】of bare rock surfaces causes their disintegration. In the dry regions of the world the wind is a powerful force in removing material from one area to another. All this is natural. But nature has also provided certain defensive forces. Bare rock surfaces are in【54】course protected by soil itself dependent initially on the weathering of the rocks. Slowly【55】surely, different types of soil with differing "profiles" evolve the main types depending primarily on the climate. The protective soil covering, once it is formed, is held together by the growth of vegetation. Grass and herbaceous plants,【56】long, branching tenuous roots, hold firmly together the surface particles. The【57】is true with the forest cover. The heaviest tropical down- pours beating on the leave of the giant trees reach the ground only【58】spray, gently watering the surface layers and penetrating along the long passages provided by the roots to the lower levels of the soil. The soil, thus protected by grass, herb, or trees, furnishes a quiet habitat for a myriad varied organisms-earth-worms that importantly modify the soil, bacteria, active in their work of converting【59】leaves and decaying vegetation into humus and food for the growing plants. Chemical action is constantly taking【60】. Soil acids attack mineral particles and salts in solution move from one layer in the soil to another.

The great storms that hit the coast start【6】innocent circling disturbances hundreds, even thousands of miles out to sea. As they travel aimlessly over water【7】by the summer sun, they are carried westward by the【8】winds. When conditions are just【9】, warm, moist air flows in【10】the bottom of such a disturbance, moves upward through it and comes out at the top. In the【11】, the moisture in this warm air produces rain, and with it the heat is converted to energy in the form. of strong winds. As the heat increases, the【12】hurricane begins to swirl in a counter-clockwise motion.
The average life of a hurricane is only about nine days, but it contains almost【13】power than we can imagine. The energy in the heat released by a hurricane's rainfall in a(n)【14】day would【15】the entire electrical needs of the United States for more than six months. Water, not wind, is the main【16】of death and destruction in a hurricane. A(n)【17】hurricane brings 6- to 12-inch downpours【18】in sudden floods.【19】is the powerful movement of the sea—the mountains of water moving toward the low-pressure hurricane center. The water level【20】as much as 15 feet above normal as it moves toward shore.
