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】______ .

H
解析
该空格前为介词of,空格后为名词短语this heavenly marvel,因此空格处应选及物动词的现在分词。原句意为“有九个安全 这一天文奇观的方法,”,因此所选动词应带有“观看”的含义,H (当场见到)最适合。
