(D)

 Most of us have seen the full moon rising(升起)over the horizon(地平线). How big the moon seems at this time! Yet hours later, when the full moon is high in the sky above us, it seems to have become much smaller –almost as if a dome(圆盆). In fact, many people do think that the full moon has changed smaller in size(尺寸)in its ride across the night sky.

Scientists have taken photos of the full moon at both its rising time and its late-night time. When the diameter(半径)of the moon is measured(测量)in these photos, it is exactly the same! The big-moon experience that we have an optical (视觉的)illusion(错觉)-a trick played on our eyes.

An ancient Greek scientist, Ptolemy, supposed that the moon on the horizon looks larger to us because we are comparing it with trees, buildings, and other things along the horizon. Yet, on the open sea-where there are no smaller things with which to compare the rising moon-the same optical illusion takes place. Much more recently, scientists are guessing that the moon looks smaller when it is high in the sky because most things look smaller when we see them with raised(抬起的)eyes.

Fill in the blanks according to the passage. Only one word for each blank.
