[主观题]

Deep inside a mountain near Sweatwater in East Tennessee is a body of water known as the L

ost Sea. It is listed by the "Guinness Book of World Records" as the world's largest underground lake. The lost Sea is part of an extensive and historical cave system called Craighead Caverns.

The caverns have been known and used since the days of the Cherokee Indian Nation. The cave expands into a series of huge rooms from a small opening on the side of the mountain. Approximately one mile from the entrance, in a room called "the Council Room", many Indian artifacts have been found. Some of the items discovered include pottery, arrowheads, weapons and jewelry.

For many years there were persistent rumors of a large underground lake somewhere in a cave, but it was not discovered until 1905. In that year, a thirteen-year-old boy named Ben Sands crawled through a small opening three hundred feet underground. He found himself in a large cave half filled with water.

Today tourists visit the Lost Sea and ride far out onto it in glass-bottomed boats powered by electric motors. More than thirteen acres of water have been mapped out so far and still no end to the lake has been found. Even though teams of divers have tried to explore the Lost Sea, the full extent of it is still unknown.

According to the passage, the lost Sea is unique because it is ______.

A．part of a historical cave system

B．the biggest underground lake in the world

C．listed in the "Guinness Book of World Records"

D．the largest body of water in Tennessee

Our generation has made such immense discoveries and achieved undreamed enrichments of the

outside of life, that it has lost touch with the inside of life. It has forgotten the true riches and beauties of its spiritual inheritance: riches and beauties that go far beyond our modern chatter about values and ideals. The mind's search for more breadth has obscured the heart's craving for more depth. Once again man has become the dupe of his own cleverness. And because it is difficult to attend to more than a few things at a time, we leave out a great range of experiences which comes in by another route and tells us of another kind of life. Our interest rushes out to the farthest limits of the universe, but we seldom take a sounding of the ocean beneath our restless keels. We get, therefore, a queer feeling that we are leaving something out. Knowledge has grown; but wisdom, savoring the deep wonder and mystery of life, lingers far behind. Thus the life of the human spirit, which ought to maintain a balance between the world visible and the world invisible, is thrown out of gear.

The title that best expresses the ideas of this passage is ______ .

A．Man's Need for Wisdom

B．The Inside of life

C．Heart vs. Mind

D．Universal Ideals

Passage 4 When most people think of a shipwreck, they imagine the remains of a huge wooden or metal boat crashed along the bottom of the ocean. Fish swim in and out of the mangled boat’s hull, and coral and seaweed cling to its sides. Meanwhile, divers with scuba gear and cameras paddle their way into the depths to explore inside the long-forgotten vessel. They might find anything from old pottery to rusty cannons to pirate gold, but one thing is certain: the deep cold water has swallowed up the ship and kept it secret for a very long time. Surprisingly, though, water is not always a necessary element in shipwreck explorations. Few people realize that many important shipwrecks can be found on land. Trading skiffs, warships, and pirate galleons alike have been found buried deep in riverbeds, hilltops, and cornfields throughout the world. The author most likely composed these two paragraphs in order to:

A、inform the reader about surprising places shipwrecks have been found.

B、describe what a person would find if he or she visited a shipwreck.

C、compare the similarities between a water-found shipwreck and a land-found shipwreck.

D、intensify the discovery of a shipwreck by surprising the reader with a new location for finding them.

第10题

there are different ways in which people try to deal with the problem of energy.one way is the greater production of common energy sources, such as coal, oil and gas.the trouble with these sources, however, is that they are not renewable.another way is energy conservation（节能）, which means using energy more efficiently.in some very cold countries people build special houses to save energy.they place materials between the inside and the outside of the walls of the house to keep the cold out and the warmth in.the house is heated by the lights, the body heat of the people and the other equipment in it.finally, renewable energy sources are used even though they are often expensive to develop.one form of these is geothermal energy.in certain parts of the world the temperature of the earth increases thirty degrees centigrade with each kilometer down.at six kilometers, therefore, it rises to nearly two hundred degrees.to get the heat, water is pumped（压:抽）down into the rocks and back up to the surface.heat from the earth is already used in certain countries.

54.How many ways of dealing with the energy problem are discussed in the text?（）

A.Two

B.Three

C.Four

D.Five

55.From the text we learn that coal（）.

A.is quite easy to produce

B.is not used most fficienty

C.is the most common source of energy

D.could be renewed only by new technology

56.The writer tells about the "special houses" because they（）.

A.show the excellent skils of the builders

OB.serve as an example of energy conservation

C.are heated by dferent soures of energy

D.are warmer than other types of houses

57.The underlined words geothermal energy in the third paragraph mean（）.

A.renewable source

B.underground source

C.heat inside the earth

D.temperature of the earth

58.at a place where the surface temperature is 15°C, how deep do you have to dig so as to get a temperature of 75°C?（）

A.One km.

B.Two km.

C.Three km.

D.Four km

Volcanoes

Geologists have been studying volcanoes for a long time. Though they have learned a great deal, they still have not discovered the causes of volcanic action. They know that the inside of the earth is very hot, but they are not sure exactly what causes the great heat. Some geologists have thought that the heat is caused by the great pressure of the earth's outer layers. Or the heat may be left from the time when the earth was formed. During the last sixty years scientists have learned about radium, uranium, thorium, and other radioactive elements. These give out heat all the time as the heat inside the earth is produced by radioactive elements.

Whatever the cause of the heat may be, we do know that the earth gets hotter the farther down we dig. In deep mines and oil wells the temperature rises about 1'F. for each 50 feet. At this rate the temperature 40 miles below the earth's surface would be over 4,000'F. This is much hotter than necessary to melt rock. However, the pressure of the rock above keeps most materials from melting at their usual melting points. Geologists believe that the rock deep in the earth may be plastic, or puttylike. In other words, the rock yields slowly to pressure but is not liquid. But if some change in the earth's crust releases the pressure, the rock melts. Then the hot, liquid rock can move up toward the surface.

When the melted rock works its way close to the earth's crust, a volcano may be formed. The melted rock often contains steam and other gases under great pressure. If the rock above gives way, the pressure is released. Then the sudden expansion of the gases causes explosions. These blow the melted rock into pieces of different sizes and shoot them high in the air. Here they cool and harden into volcanic ash and cinders. Some of the material falls around the hole made in the earth's surface. The melted rock may keep on rising and pour out as lava. In this way, volcanic ash, cinders, and lava build up the cone-shaped mountains that we call volcanoes.

The subject of this passage is the ______.

A．interior of the earth

B．results of volcanic action

C．work of geologists

D．formation of volcanoes
