Passage 3(2024 衡阳一模)
You might have seen beautiful rainbows in the sky before. They form when sunlight falls on water drops in the air. But in fact, moonlight can also create rainbows in the same way. They are called “moonbows”. They are similar to rainbows, but they are created by moonlight.
Moonbows are more unusual than rainbows. Different weather and astronomical (天文学的) conditions have to be just right for moonbows to be created. The moon has to be very low in the sky—less than 42 degrees from the horizon(地平线). The moon has to be a full moon or nearly full. The sky must be very dark for a moonbow to be watched clearly—any bright light can obscure it. Water drops must appear in the air in the opposite direction of the moon. Moonbows appear on the opposite side of the moon and usually look white to the human eye. This is because their colors are not bright enough to be noticed by the human eye.
Moonbows appear more often in some locations around the world. Most of these locations have waterfalls, which create thin fog in the air. Some of these locations are Yosemite National Park in California, Cumberland Falls State Resort Park in Kentucky and Waimea in Hawaii, US.
Moonbows do really happen. So at a certain time and a certain place, when a moonbow happens to appear, you can’t miss it if you’re right there.
8.According to the first two paragraphs, moonbows are ______.
A.seen during the day
B.more difficult to form
C.created by sunlight
9.The underlined word “obscure” probably means “______”.
A.produce B.drop C.cover
10.From the passage, we can know that ______.
A.moonbows happen more often than rainbows
B.moonbows are similar to rainbows
C.moonbows always appear colorful when we see them in the dark
11.Which of the following can be one of the conditions for a moonbow to form?
A.A half moon hangs high in the bright sky.
B.A full moon is 50 degrees from the horizon.
C.Water drops are in the opposite direction of the moon.

答案： 语篇解读 本文为说明文，主要介绍了月虹形成的原因和条件等。
8.B 细节理解题。根据“Moonbows are more unusual than rainbows. Different weather and astronomical conditions have to be just right for moonbows to be created.”可知，月虹比彩虹少见，因为它更难形成，故选B。
9.C 词义猜测题。本句提到天空必须非常暗，才能清晰地看见月虹，所以任何光都可能遮住月虹。单词“obscure”表示“遮住”，与cover同义，故选C。
10.B 细节理解题。根据第一段的“They are similar to rainbows, but they are created by moonlight.”可知，月虹和彩虹很相似。故选B。
11.C 细节理解题。根据第二段的“Water drops must appear in the air in the opposite direction of the moon.”可知，水滴与月亮的方向相反是形成月虹的条件之一。故选C。
