A.The theory is likely to be developed eventually, but then subsequently supplanted but more attractive models.
B.The theory, given its advanced nature, is likely to be even more significant to scientists than Newton's Principia was in its time.
C.The appearace of the theory will most likely underscore the hubris of scientists in attempting to describe nature.
D.The theory is certain to appear, and will serve undermine the pedagogical errors made by nineteenth-century professors.
E.The appearance of the theory is likely to unravel the existing structure of physics, discrediting the field's most fundamental assumptions.
SECTION C NEWS BROADCAST
Directions: In this section you will hear everything ONCE ONLY. Listen carefully and then answer the questions that follow. At the end of each news item, you will be given 10 seconds to answer the questions.
听力原文: Voice One: This is what scientists say the sun sounds like--- the equivalent of a solar heartbeat. Solar scientists used listening devices to unravel some of the mysteries of Earth' s nearest star. It' s not the actual sound. Sound can' t travel through the vacuum of space. But [this is] a recreation based on the waves recorded by the devices.
Each pitch corresponds with the movement and vibrations of various hot gasses as they flow like rivers beneath the sun' s surface--- similar to how trade winds blow on Earth.
Scientists translate the sounds they make into images. This allows a unique glimpse inside the sun' s complex architecture, to answer questions about its temperature, chemical makeup, and how gasses inside ebb and flow.
Voice Two: What we' re finding is that there are very interesting structures inside. There' s an equatorial belt of faster moving material. And then, farther up near the poles, we believe that there' s a jet stream of material moving about 60 miles an hour up at a very north latitude.
How do the scientists measure the pitch?
A.According to the movement and vibrations of hot gasses
B.The trade winds blow on Earth
C.The rivers
D.The sound travel through the space
