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-filth only 30 times【C3】______ the past 5000 years, the last time in 1954.

答案
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“有几个安全______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。
