Solar eclipses occur when the moon【C1】______ between the earth and the sun, and the moon’s shadow covers part of the earth; and a total solar eclipse takes place when the moon’s shadow blocks out the sun【C2】______ . What made this particular solar eclipse unique was that this event has occurred on December twenty-fifth only 30 times【C3】______ the past 5000 years, the last time in 1954.

G

该空格前为形容词性物主代词sun’s,因此空格处应选名词。原句意为“你可以利用望远镜……将太阳的______投射到一张纸上,进而观测日食”,因此所选名词应包含“影子”、“影像”等含义,G(图像)最适合。
