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.

Sunglasses can block out some of the sun’s ultraviolet rays, but the results can be very deceptive. The eye’s natural【C8】______ to this darkened state when wearing sunglasses is to make the pupil larger, which allows in more light and can【C9】______ the damage to your eye.
You can watch an eclipse by projecting the sun’s【C10】______ on a piece of paper either by using a telescope, or easier yet, by creating a pinhole in a piece of paper and viewing the result on another piece of paper, thus called a pinhole projector.
[A] lively [I] during
[B] passes [J] intensify

选项
答案
I
解析
该空格后为表示时间的名词短语the past 5000 years,因此空格处应选可以引导时间状语的介词。原句意为“这种情况______过去五千年在12月25日只出现过30次”,因此所选介词应表示“在……(时间)之间”,I(在……期间)最适合。
