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.
But people must be exceptionally【C4】______ when attempting to view a solar eclipse. Without taking precautionary【C5】______ ,one can permanently damage the retina of the eye; however, there are several safe methods of【C6】______ this heavenly marvel.

【C7】
选项
答案
N
解析
该空格前为形容词性物主代词sun’s,空格后为名词rays,因此空格处应选名词、形容词、动词过去分词等作定语。原句意为“你可以利用日食安全眼镜来观看日食,该眼镜可以过滤掉太阳的______光线”;再结合上下文中提到的观看日食可能损伤眼睛可知,N(有害的)最适合。
