D. the dangers of invisible radiation.
正确答案是

Now go through TEXT G and answer question 53.
　
When we accept the evidence of our unaided eyes and describe the Sun as a yellow star, we have summed up the most important single fact about it -- at this moment in time. It appears probable, however, that sunlight will be the color we know for only a negligibly small part of the Sun's history.
　
Stars, like individuals, age and change. As we look out into space, we see around us stars at all stages of evolution. There are faint blooded dwarfs so cool that their surface temperature is a mere 4,000 degrees Fahrenheit, there are searing ghosts blazing at 100,000 degrees Fahrenheit and almost too hot to be seen for the great part of their radiation is in the invisible ultraviolet range. Obviously, the "daylight" produced by any star depends on its temperature, today (and for ages to come) our Sun is at about 10,000 degrees Fahrenheit and this means that most of the Sun's light is concentrated in the yellow band of the spectrum falling slowly in intensity toward both the longer and shorter light waves.
　
That yellow "hump" will shift as the Sun evolves and the light of day will change accordingly. It is natural to assume that as the Sun grows older and uses up its hydrogen fuel -- which it is now doing at the sparkling rate of half a billion tons    a second -- it will become steadily colder and colder.

正确答案是

Now go through TEXT H quickly and answer question 54.
　
Many artists late in the last century were in search means to express their individuality. Modern dance was one of the ways some of these people sought to free their creative spirit. At the beginning there was no exacting technique, no foundation from which to build. In later years trial, innovators even drew from what they considered the dread ballet, but first they had to discard all that was academic to that the new could be discovered. The beginning of modern dance were happening before Isadora Duncan, but she was the first person to bring the new dance to general audiences and see it accepted and    acclaimed.
　
Her search for natural movement form sent her to nature. She believed movement should be as natural as the swaying of the trees and the rolling of the sea, and should be in harmony with the movements of the Earth. Her great contributions are in three areas.
　
First, she began the expansion of the kinds of movements that could be used in dance. Before Duncan danced, ballet was the only type of dance performed in concert. In the ballet the feet and legs were emphasized, with virtuosity shown by complicated, codified positions and movements. Duncan performed dance by using all her body in the freest possibly way. Her dance stemmed from her soul and spirit. She was one of the pioneers who broke tradition so others might be able to develop the art.
　
Her second contribution lies in dance costume. She discarded corset, ballet shoes, and stiff costumes. There were replaced with flowing Grecian tunics, bare feet, and unbound hair. She believed in the natural body being allowed to move freely, and her dress displayed this ideal.
　
Her third contribution was in the use of music. In her performances she used the symphonies of great masters, including Beethoven and Wagner, which was not the usual custom.
　
She was as exciting and eccentric in her personal life as in her dance.
