Unit 4 Astronomy:the science of the stars Ⅰ.阅读理解 A (2018山西重点中学协作体) One of my first memories as a child in the 1950s was a discussion I had with my brother in our tiny bedroom in the family house in Bethlehem,Pennsylvania. We had heard in school about a planet called Pluto.It was the farthest,coldest,and darkest thing a child could imagine.We guessed how long it would take to die if we stood on the surface of such a frozen place wearing only the clothes we had on.We tried to figure out how much colder Pluto was than Antarctica,or than the coldest day we had ever experienced in Pennsylvania. Pluto,which famously was downgraded from a “major planet” to a“dwarf planet”(矮行星)in 2006,captured our imagination because it was a mystery that could complete our picture of what it was like at the most remote corners of our solar system. Pluto’s underdog discovery story is part of what makes it so attractive.Clyde Tombaugh was a Kansas farm boy who built telescopes out of spare auto parts,old farm equipment and self-ground lenses.As an assistant at Lowell Observatory in Flagstaff,Arizona,Tombaugh’s task was to search millions of stars for a moving point of light,a planet that the observatory’s founder thought existed beyond the orbit of Neptune.On February 18,1930,Tombaugh found it.Pluto was the first planet discovered by an American,and represented a moment of light in the midst of the Great Depression’s dark encroachment (入侵). Pluto is much more than something that is not a planet.It’s a reminder that there are many worlds out there beyond our own and that the sky isn’t the limit at all.We don’t know what kinds of fantastic variations on a theme nature is capable of making until we get there to look. 1.Why did Pluto become famous in 2006 according to the passage?
