On December 25, 2000, many people across North America received a rare Christmas treat when the moon passed in front of the sun resulting in a partial solar eclipse.
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.

【C9】
选项
答案
J
解析
该空格前为情态动词call,空格后为名词damage,因此空格处应选及物动词原形。原句意为“让更多的阳光进入瞳孔,可以______对你视力的伤害”,因此所选动词应意为“加重”,J(加强)最适合。
