         The spectacular aurora light displays that appear in Earth's atmosphere around the north and south magnetic poles were once mysterius phenomena.Now,scientists have data from satellites and ground-based observations from which we know that the aurora brilliance is an immense electrical discharge similar to that occurring in an neon sign.

        To understand the cause of auroras,first picture the Earth enclosed by its magnetosphere,a huge region created by the Earth's magnetic field.Outside the magnetosphere,blasting toward the earth is the solar winds,a swiftly moving plasma of ionized gases with its own magnetic filed.Charged particles in this solar wind speed earthward along the solar wind's magnetic lines of force with a spiraling motion.The Earth's magnetosphere is a barrier to the solar winds,and forces the charged particles of the solar wind to flow around the magnetosphare itself.But in the polar regions,the magnetic lines of force of the Earth and of the solar wind bunch together.Here many of the solar wind's charged particles break through the magnetosphere and enter Earth's magnetic field.They then spiral back and forth between the Earth's magnetic poles very rapidly.In the polar regions,electrons from the solar wind ionize and excite the atoms and molecules ofthe upper atmosphere,causing them to emit aurora radiations of visible light.

        The colors of an aurora depend on the atoms emitting them.The dominant greenishwhite light comes from low energy excition of oxygen atoms.During huge magnetic storms oxygen atoms also undergo high energy excitation and emit a crimson light.Excited nitrogen atoms contributed bands of color varying from blue to violed.

        Viewed from outer space,auroras can be seen as dimly glowing belts wrapped around each of the Earth's magnetic poles.Each aurora hangs like a curtain of light stretching over the polar regions and into the higher latitudes.When the solar flares that result in magnetic storms and aurora activity are very intense,aurora displays may extend as far as the  southern regions of the United States.Studies of auroras have given physicists new information about the behavior of plasmas,which has helped to explain the nature of outer space and is being applied in attempts to harness energy from the fusion of atoms.

d.the excitation of atoms is low

8.The passage supports which of the following statements about scientists' understanding of aurora?

a.Before advances in technology,including satellites,scientists knew little about auroras.

b.New knowledge about the fusion of atoms allowed scientists to learn more about auroras.

c.Scientists cannot explain the cause of the different colors in auroras.

d.Until scientists learn more about plasma physics,little knoeledge about auroras will be available.

a."magnetosphere"(line7)

b."electrons"(line 16)

c."ionize"(line 16)

d."fusion"(line 30)

             Just two months after the flight of Apollo 10,the Apollo 11 astronouts made their historic landing on the surface of the moon.This momentous trip for humanity also provided scientists with an abundance of material for study;from rock and soil samples brought back from the Moon,scientists have been able to determine much about the composition of the Moon as well as to draw inferences about the development of the Moon from its composition.               The Moon soil that came back on Apollo 11 contains small bits of rock and glass which were probably ground from larger rocks when meteors impacted with the surface of the Moon.The bits of glass are spherical in shape and constitute approximately half of the Moon soil.Scientists found no trace of animal or plant life in this soil.               In addition to the Moon soil,astronauts gathered two basic ...

             During the heyday of the railroads,when Ameria's rail system provided the bulk of the country's passenger and freight transportation,various types of railroad cars were in servive to accomplish the varied tasks handled by the railroads.One type of car that was not available for public use prior to the civil War,however,was a sleeping car,ideas for sleeping cars abounded at the time, but these ideas were unworkable.It unfortunately took the death of a president to make the sleeping car a viable reality.               Cabinet-maker George M.Pullman had recognized the demand for sleeping cars and had worked on developing experimental models of sleeping cars in the decade leading up to the Civil War.However,in spite of the fact that he had made successful test runs on the chicago and Alton Railroads with his models,he was unable to sell his idea because his models were too wide and too high for...

         Today ,the most universally known style of both men and women is jeans;these trousers are worn throuhout the world on a variety of occasions and in diverse situations.Also called levis or denims,jeans have an interesting history,one that is intermixed with the derivation of the words jeans,denims,and levis.               The word jeans is derived from the name of the place where a similar style of plants developed.In the sixteenth century,sailors from Genoa,Italy,wore a rather unique type of cotton trousers.In the French language,the word for the city of Genoa and for the people from that city is Genes;this name became attached to the specific style of pants worn by the sailors from this city and developed into the word jeans that today describes the descendents of the Genovese sailors' cotton pants.               Similar to the word jeans,the word denim is also derived...
